Purpose To evaluate the clinical outcomes of patients with a minimum 2-year follow-up following contemporary patellofemoral inlay arthroplasty (PFIA) and to identify potential risk factors for failure in a multi-center study. Methods All patients who underwent implantation of PFIA between 09/2009 and 11/2016 at 11 specialized orthopedic referral centers were enrolled in the study and were evaluated retrospectively at a minimum 2-year follow-up. Clinical outcomes included the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, the Knee Injury and Osteoarthritis Outcome Score (KOOS), the Tegner Scale, the visual analogue scale (VAS) for pain, and subjective patient satisfaction. Pre- and perioperative risk factors were compared among failures and non-failures to determine potential risk factors. Results A total of 263 patients (85% follow-up rate) could be enrolled. The mean age at the time of index surgery was 49 ± 12 years with a mean postoperative follow-up of 45 ± 18 months. The overall failure rate was 11% (28 patients), of which 18% (5 patients) were patients with patella resurfacing at index surgery and 82% (23 patients) were patients without initial patella resurfacing. At final follow-up, 93% of the patients who did not fail were satisfied with the procedure with a mean transformed WOMAC Score of 84.5 ± 14.5 points, a mean KOOS Score of 73.3 ± 17.1 points, a mean Tegner Score of 3.4 ± 1.4 points and a mean VAS pain of 2.4 ± 2.0 points. An increased BMI was significantly correlated with a worse postoperative outcome. Concomitant procedures addressing patellofemoral instability or malalignment, the lack of patellofemoral resurfacing at the index surgery and a high BMI were significantly correlated with failure in our patient cohort. Conclusion Patellofemoral inlay arthroplasty shows high patient satisfaction with good functional outcomes at short-term follow-up and thus can be considered a viable treatment option in young patients suffering from isolated patellofemoral arthritis. Patellar resurfacing at index surgery is recommended to decrease the risk of failure. Level of evidence Retrospective case series, Level IV.

Die isolierte Arthrose des Patellofemoralgelenkes stellt eine seltene und komplexe Erkrankung dar. Nach Ausschopfen der konservativen Therapie stehen dem Orthopaden diverse weichteilige und knocherne rekonstruktive Verfahren sowie knorpelregenerative Verfahren zur Verfugung. Bei fehlgeschlagener oder unbefriedigender Therapie wird die Patellofemoralprothese als Therapiealternative weiterhin kontrovers diskutiert. Bei genauerer Betrachtung der Studien zeigen sich vielversprechende Ergebnisse bei korrekter Indikationsstellung und Patientenselektion. Die unterschiedlichen Prothesendesigns liefern gute postoperative Ergebnisse bei Beachtung von generellen und spezifischen Risiken. Die aktuelle Generation der patellofemoralen Inlay-Prothesen zeigt eine hohe Patientenzufriedenheit mit signifikanten Verbesserungen der Kniefunktion und Schmerzlinderung in mittelfristen Ergebnissen, bei allerdings nicht unerheblicher Revisionsrate.

BackgroundAlthough of high relevance for clinical decision making, there exists no consensus throughout the literature of the terms “acute” and “traumatic” used in the classification of rotator cuff tears. With differing definitions, the comparability of outcome studies may be limited. The aim was to provide a detailed systematic review of the definitions used in the literature and present a suggestion for a standardization in nomenclature based on the findings.MethodsFour different internet databases were searched in February 2020 using the terms (“acute” OR “traumatic” OR “trauma” OR “athlete” OR “young”) AND (“rotator cuff tears” OR “rotator cuff tear” OR “rotator cuff” OR “rotator cuff rupture” OR “supraspinatus” OR “infraspinatus” OR “subscapularis” OR “teres minor”). Prospective, retrospective, cohort and case–control studies as well as case series were included. Systematic reviews, cadaveric or laboratory studies and studies on non-traumatic or non-acute rotator cuff tears were excluded.ResultsThe literature search conducted 10,349 articles of which 10,151 were excluded based on the title, 119 based on the abstract and 33 based on the manuscript. A total of 46 studies were finally included for review and subsequently analyzed. Overall, there exists no consensus neither on the term “acute” nor on “traumatic” in the context of rotator cuff tears in the literature. The time span for acute injuries ranged between 2 weeks and 6 months. For traumatic injuries, only 20% of the selected studies described a specific and adequate injury mechanism in combination with adequate imaging.ConclusionThe term “acute” should be reserved for RCT showing muscle edema, wavelike appearance of the central part of the torn tendon and joint effusion, which typically requires adequate imaging within 2 weeks from trauma. Repair of acute tears should occur within 8 weeks from trauma to benefit from possibly superior biological healing capacities. The term “traumatic” should be used for a sudden onset of symptoms in a previously asymptomatic patient, triggered by an adequate trauma, e.g., a fall on the retroverted arm with an axial cranioventral force or a traumatic shoulder dislocation.

Purpose The aim of this study was, to investigate the rate of return to sports (RTS) and physical activity after implantation of PFIA and to identify factors predictive of improved postoperative sporting ability. Methods Sixty-two patients with a mean age of 46 ± 11 years, who underwent implantation of PFIA at the senior authors’ institution, were enrolled. They were prospectively evaluated preoperatively and at a minimum of 2 years postoperatively with a mean follow-up of 60 ± 25 months. Clinical outcomes, return to sports and activity, type of sport or activity, subjective satisfaction, and frequency were evaluated by questionnaire. Results The transformed overall Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score improved from 67 ± 16 to 77 ± 19 (p = 0.003), Tegner activity scale results improved from 3 ± 2 points to 4 ± 1 points (p p p = 0.001). Ninety-four percent of the patients who did not fail could return to the same or higher level of sports, with 74% of the patients reporting an improved ability to perform sports. No preoperative factors could be detected to significantly influence RTS after surgery. Conclusions PFIA is a valid treatment option for the active patient with end-stage isolated patellofemoral OA. Reliable improvements in knee function, pain, and participation in low-impact sports were found. Level of evidence IV.

Purpose The purpose of this study was to identify modifiable factors associated with research activity among residents working in orthopedic surgery and traumatology. Methods Residents at 796 university-affiliated hospitals in Austria, Germany, and Switzerland were invited to participate. The online survey consisted of questions that ascertained 13 modifiable and 17 non-modifiable factors associated with the residents’ current research activities. Responses of 129 residents were analyzed. Univariate linear regression was used to determine the association of individual factors with the current research activity (hours per week). The impact of significant non-modifiable factors (with unadjusted p values Results The univariate analysis demonstrated six non-modifiable factors that were significantly associated with the current research activity: a University hospital setting (p p = 0.024), Swiss residents (p = 0.0012), the completion of a dedicated research year (p = 0.007), female gender (p = 0.016), and the department’s size (p = 0.048). Multivariate regression demonstrated that the number of protected research days per year (p p p Conclusions As hypothesized, more frequent and predictable protected research days were associated with higher research activity among residents in orthopedic surgery and traumatology.

To report the clinical and structural outcomes for non-pseudoparalytic irreparable posterosuperior rotator cuff tears treated with superior capsule reconstruction (SCR) using dermal allograft (DA).Patients who underwent SCR using DA with a mean thickness of 3 mm for irreparable posterosuperior rotator cuff tears and underwent surgery at least 2 years earlier were included. Outcomes were assessed prospectively by the American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation, and Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores; patient satisfaction; and visual analog scale for pain. Structurally, acromiohumeral distances (AHDs) were assessed both preoperatively and postoperatively (standard radiographs). Graft integrity was assessed by magnetic resonance imaging. Clinical failures were reported.We included 22 patients with a mean age of 56 years (range, 41-65 years) and a mean follow-up period of 2.1 years (range, 2-3 years). The ASES score improved from 54.0 to 83.9 (P.001); the Single Assessment Numeric Evaluation score improved from 44.9 to 71.4 (P.001); and Quick Disabilities of the Arm, Shoulder and Hand score (QuickDASH) improved from 37.6 to 16.2 (P = .001). Of the patients, 85% achieved an improvement in the ASES score that exceeded the minimal clinically important difference (11.1 points). The median patient satisfaction rating was 8.5 (range, 1-10). The median preoperative visual analog scale score decreased from 4 to 0 (range, 0-3) postoperatively (P.001). Complete radiographs of 19 of 22 patients (86%) were obtained at a mean of 5.2 months (range, 1.4-10 months) postoperatively and showed a significant increase in the mean AHD from 7.0 mm preoperatively to 8.3 mm postoperatively (P = .029). Postoperative magnetic resonance imaging scans were obtained in 95% of the patients (21 of 22) at a mean of 2.5 months (range, 0.3-10.2 months) postoperatively and showed graft integrity rates of 100% (21 of 21) on the tuberosity side, 76% (16 of 21) at the midsubstance, and 81% (17 of 21) on the glenoid side. No significant differences in clinical outcome scores (P0.930) were found in patients with intact grafts versus those with torn grafts. The number of previous shoulder surgical procedures was a negative predictor of clinical outcome. There was 1 clinical failure.SCR using DA for irreparable tears improves outcomes with high satisfaction and high graft integrity at short-term follow-up. Graft integrity, although correlated with an increased AHD, had no correlation with clinical outcomes at final follow-up.Level IV, case series.

Epidemiologic data of proximal hamstring avulsions have mainly been reported in relatively small patient cohorts. Detailed information on patient demographics, injury mechanism, and injury patterns is lacking in the literature. Since these injuries are rare and frequently misdiagnosed, a better understanding may help to increase awareness and to improve diagnosis of proximal hamstring avulsions. A chart review was performed to identify all patients who had undergone surgical repair for complete proximal hamstring avulsions between 01/2006 and 02/2019 at the authors’ institution. The following demographic and injury-specific data were obtained: Sex, age, body mass index (BMI), cause of injury (sports, activities of daily living, and others), presence of neurologic symptoms referable to the sciatic nerve, time to surgery, injury pattern (affected tendons), tendon retraction, and type of injury according to Wood et al.`s classification (Type 1: osseous avulsions, Type 2: tear at the musculotendinous junction, Type 3: incomplete avulsion from bone, Type 4: complete avulsion with only minimal retraction, and Type 5: complete avulsion with retraction > 2 cm). Data were analyzed for the entire study population and group comparison was performed with regard to sex, cause of injury, and the type of injury. A total of 263 patients were included (53% male). The mean age was 49 ± 13 years with most patients (56%) aged between 45–59 years. Most injuries occurred while participating in sports (52%) and injury type 5 was most commonly diagnosed (66%). Five percent of patients had sensory deficits referable to the sciatic nerve. Gender comparison showed that female patients were significantly older, predominantly represented in the age group 45–59 years, and most commonly injured during activities of daily living, whereas male patients were significantly more often represented in younger age groups, and the most common cause of injury was sports. Compared to Type 4 and 5 injuries, patients with a Type 1 injury were significantly younger and had a significantly longer time to surgery. Proximal hamstring avulsion occurs predominately in the middle-aged patient and only rarely in patients under the age of 30 years. No gender dominance exists. Female patients are typically older and get injured during activities of daily living, whereas male patients are younger and get injured more often during sports. These epidemiologic data may help physicians to make an accurate and early diagnosis. IV.

Shoulder stiffness is characterized by restriction of the active and passive movement of the glenohumeral joint. The stiffness is ultimately caused by fibrosis and the resulting contracture of the glenohumeral joint capsule and its ligaments; however, the term stiff shoulder is only a descriptive umbrella term that must be further defined as the course of the disease and the recommended treatment are decisively influenced by the cause of the shoulder stiffness. Primary shoulder stiffness, also known as idiopathic shoulder stiffness or "frozen shoulder", must be distinguished from various forms of secondary shoulder stiffness and often occurs in three stages, which can all last for several months to years: the initial "freezing phase", followed by a "frozen phase" and finally a "thawing phase". Although primary shoulder stiffness is a frequent pathological alteration with an prevalence of 2-5% in the general population, the exact etiology remains largely unknown; however, there is consensus throughout the literature that certain systemic pathologies, such as diabetes mellitus are associated with a higher incidence of primary shoulder stiffness.

PURPOSE To evaluate the clinical outcomes and structural integrity of primary subpectoral biceps tenodesis using an all-suture anchor onlay technique for long head of the biceps (LHB) tendon pathology. METHODS We conducted a retrospective case series with prospectively collected data of patients who underwent primary, isolated subpectoral biceps tenodesis with a single all-suture anchor onlay fixation between March 2017 and March 2019. Outcomes were recorded at a minimum follow-up of 12 months based on assessments of the American Shoulder and Elbow Surgeons (ASES) score, LHB score, and elbow flexion strength and supination strength measurements. The integrity of the tenodesis construct was evaluated using ultrasound. RESULTS Thirty-four patients were available for clinical and ultrasound examination at a mean follow-up of 18 ± 5 months. The mean ASES score significantly improved from 51.0 ± 14.2 points preoperatively to 89.8 ± 10.5 points postoperatively (P < .001). The minimal clinically important difference for the ASES score was 8.7 points, which was exceeded by 31 patients (91.2%). The mean postoperative LHB score was 92.2 ± 8.3 points. Regarding subcategories, an average of 47.2 ± 6.3 points was reached for "pain/cramps"; 26.4 ± 6.1 points, "cosmesis"; and 18.6 ± 2.6 points, "elbow flexion strength." Both elbow flexion strength and supination strength were similar compared with the nonoperated side (P = .169 and P = .210, respectively). In 32 patients, ultrasound examination showed an intact tenodesis construct, whereas 2 patients (5.9%) sustained failure of the all-suture anchor fixation requiring revision. CONCLUSIONS Primary subpectoral biceps tenodesis using an all-suture anchor onlay technique for pathology of the LHB tendon provides reliable clinical results and a relatively low failure rate (5.9%).

Purpose To determine the sensorimotor and clinical function of patients with confirmed successful outcome after either undergoing acromioclavicular joint (ACJ) stabilization, Bankart repair (BR), or rotator cuff repair (RC), and to compare these measures to the contralateral, healthy side without history of previous injuries or surgeries of the upper extremity. It was hypothesized that patients of each interventional group would have inferior sensorimotor function of the shoulder joint compared to the contralateral, healthy side, while presenting with successful clinical and functional outcomes. Methods Three intervention groups including ten patients who had confirmed successful clinical and functional outcomes after either undergoing ACJ stabilization, BR, or RC were evaluated postoperatively at an average follow-up of 31.7 ± 11.6 months. Additionally, a healthy control group (CG) of ten patients was included. Clinical outcomes were assessed using the Constant–Murley (CM) and American Shoulder and Elbow Surgeons (ASES) Score. Pain was evaluated using the visual analogue scale (VAS). Sensorimotor function was assessed by determining the center of pressure (COP) of the shoulder joint in a one-handed support task in supine position on a validated pressure plate. Results Each interventional group demonstrated excellent clinical outcome scores including the CM Score (ACJ 83.3 ± 11.8; BR 89.0 ± 10.3; RC 81.4 ± 8.8), ASES Score (ACJ 95.5 ± 7.0; BR 92.5 ± 9.6; RC 96.5 ± 5.2), and VAS (ACJ 0.5 ± 0.9; BR 0.5 ± 0.8; RC 0.5 ± 0.8). Overall, the CG showed no significant side-to-side difference in COP, whereas the ACJ-group and the BR-group demonstrated significantly increased COP compared to the healthy side (ACJ 103 cm vs. 98 cm, p = 0.049; BR: 116 cm vs. 102 cm, p = 0.006). The RC-group revealed no significant side-to-side difference (120 cm vs. 108 cm, n.s.). Conclusion Centre of pressure measurement detected sensorimotor functional deficits following surgical treatment of the shoulder joint in patients with confirmed successful clinical and functional outcomes. This may indicate that specific postoperative training and rehabilitation protocols should be established for patients who underwent surgery of the upper extremity. These results underline that sensorimotor training should be an important component of postoperative rehabilitation and physiotherapeutic activities to improve postoperative function and joint control.

As concomitant hyperlaxity has been identified as an independent risk factor for failure following anterior shoulder stabilization, the treatment of this special pathology remains challenging. There is a broad consensus that a clear differentiation to multidirectional instability and isolated anteroinferior instability should be ensured to avoid unsatisfactory outcomes. Typical features of this patient collective include positive clinical tests for anteroinferior instability and multidirectional shoulder hyperlaxity, findings of an anterior labral lesion and general capsular redundancy in the radiologic assessment, while tests for posterior instability are negative. Surgical treatment should consist of an anteroinferior capsulolabroplasty with concomitant posteroinferior plication to reduce pathological capsular volume. Although there is a lack of clinical evidence, biomechanical investigations suggest that a four-anchor construct with three anterior anchors and one posteroinferior anchor may be sufficient to restore glenohumeral stability. This surgical approach is presented and discussed in the current article.

PurposeTo analyze whether preoperative patellofemoral anatomy is associated with clinical improvement and failure rate after isolated patellofemoral arthroplasty (PFA) using a modern inlay-type trochlear implant.MethodsProspectively collected 24 months data of patients treated with isolated inlay PFA (HemiCAP®Wave, Arthrosurface, Franklin, MA, USA) between 2009 and 2016, and available digitalized preoperative imaging (plain radiographs in three planes and MRI) were retrospectively analyzed. All patients were evaluated using the WOMAC score, Lysholm score, and VAS pain. Patients revised to TKA or not achieving the minimal clinically important difference (MCID) for the total WOMAC score or VAS pain were considered failures. Preoperative imaging was analyzed regarding the following aspects: Tibiofemoral OA, patellofemoral OA, trochlear dysplasia (Dejour classification), patellar height (Insall–Salvati index [ISI]; Patellotrochlear index [PTI]), and position of the tibial tuberosity (TT–TG and TT–PCL distance).ResultsA total of 41 patients (61% female) with a mean age of 48 ± 13 years could be included. Fifteen patients (37%) were considered failures, with 5 patients (12%) revised to TKA and 10 patients (24%) not achieving MCID for WOMAC total or VAS pain. Failures had a significantly higher ISI, and a significantly lower PTI. Furthermore, the proportion of patients with a pathologic ISI (> 1.2), a pathologic PTI (ConclusionPreoperative patellofemoral anatomy is significantly associated with clinical improvement and failure rate after isolated inlay PFA. Less improvement and a higher failure rate must be expected in patients with patella alta (ISI > 1.2 and PTI 21 mm). Concomitant procedures such as tibial tuberosity transfer may, therefore, be considered in such patients.Level of evidenceLevel III, retrospective analysis of prospectively collected data.

Background: Instability of the sternoclavicular (SC) joint is a rare but potentially devastating pathologic condition, particularly when it occurs in young or active patients, where it can lead to persistent pain and impairment of shoulder function. SC joint reconstruction using a hamstring tendon autograft is a commonly used treatment option, but midterm results are still lacking. Purpose/Hypothesis: The purpose of this study was to assess the clinical outcomes, survivorship, and return-to-sports rate after SC joint reconstruction using a hamstring tendon autograft in patients suffering from SC joint instability. We hypothesized that SC joint reconstruction would result in good clinical outcomes, high rate of survivorship, and a high rate of return to sports. Study Design: Case series; Level of evidence, 4. Methods: All patients who underwent SC joint reconstruction with a hamstring tendon autograft for SC joint instability, with a minimum 5-year follow-up, were included. Patient-reported outcomes were assessed prospectively by the use of the American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numerical Evaluation (SANE) score, short version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) score, 12-Item Short Form Health Survey (SF-12) physical component summary (PCS), and patient satisfaction. Survivorship of reconstruction was defined as no further revision surgery or clinical failure such as recurrent instability or subluxation events. Return to sports and pain were assessed using a customized questionnaire. Results: A total of 22 shoulders that underwent SC joint reconstruction, with a mean patient age of 31.3 years (range, 15.8-57.0 years) at the time of surgery, were included. At the final evaluation, 18 shoulders, with a mean follow-up of 6.0 years (range, 5.0-7.3 years), completed a minimum 5-year follow-up. All clinical outcome scores improved significantly from preoperatively to postoperatively: ASES (50.0 to 91.0; P = .005), SANE (45.9 to 86.0; P = .007), QuickDASH (44.2 to 12.1; P = .003), and SF-12 PCS (39.4 to 50.9; P = .001). Median postoperative satisfaction was 9 (range, 7-10). The construct survivorship was 90% at 5-year follow-up. There were 2 patients with failed treatment at 82 and 336 days postoperatively because of instability or pain who underwent revision SC joint reconstruction and capsulorrhaphy. Another patient had a superficial wound infection, which was debrided once and resulted in a good clinical outcome. Of the patients who answered optional sports activity questions, 15 (17 shoulders, 77%) participated in recreational or professional sports before the injury. At final follow-up, 14 patients (16 of 17 shoulders, 94%) returned to their preinjury level of sports. The visual analog scale score for pain today ( P = .004) and pain at its worst ( P = .004) improved significantly from preoperatively to postoperatively. Conclusion: SC joint reconstruction with a hamstring tendon autograft for SC joint instability resulted in significantly improved clinical outcomes with high patient satisfaction and 90% survivorship at midterm follow-up. Furthermore, 94% of this young and high-demand patient population returned to their previous level of sports. Concerns in terms of advanced postinstability arthritis were not confirmed because a significant decrease in pain was found after a minimum 5-year follow-up.

Background: The arthroscopic “bony Bankart bridge” (BBB) repair technique was recently shown to successfully restore shoulder stability at short-term follow-up, but longer-term outcomes have not yet been described. Purpose: To report the outcomes at minimum 5-year follow-up after BBB repair for anterior shoulder instability with a bony Bankart lesion. Study Design: Case series; Level of evidence, 4. Methods: Patients were included if they sustained a bony Bankart lesion, were treated with a BBB technique, and were at least 5 years postoperative. Patients were excluded if they underwent concomitant rotator cuff repair or an open bone fragment reduction. All patients were assessed with the following measures preoperatively and at final evaluation: QuickDASH (Quick Disabilities of the Arm, Shoulder and Hand), American Shoulder and Elbow Surgeons, Single Assessment Numeric Evaluation, and 12-Item Short Form Health Survey (SF-12) Physical Component Summary. Results: From 2008 to 2012, 13 patients who underwent BBB met the inclusion criteria with a mean age of 39.6 years (range, 19.1-68.8 years) and a mean follow-up of 6.7 years (range, 5.1-9.0 years). Mean time from most recent injury to surgery was 6.3 months (range, 1 day–36 months). The mean glenoid bone loss was 22.5% (range, 9.1%-38.6%). Mean SF-12 scores demonstrated significant improvement from 45.8 (SD, 9.7) preoperatively to 55.1 (SD, 5.9) at a mean follow-up of 6.7 years. At final follow-up, the mean American Shoulder and Elbow Surgeons score was 93.1 (range, 68.3-100); the mean QuickDASH score, 6.2 (range, 0-25); and the mean Single Assessment Numeric Evaluation score, 92.8 (range, 69-99). None of the patients progressed to further shoulder surgery. Three of 13 patients (23%) reported subjective recurrent instability. At final follow-up, 9 of 12 (75%) patients indicated that their sports participation levels were equal to their preinjury levels. Median patient satisfaction at final follow-up was 10 of 10 points (range, 3-10). Conclusion: The arthroscopic BBB technique for patients with anterior bony Bankart lesions can restore shoulder stability, yield durable improvements in clinical outcomes, and provide a high return-to-sport rate at a minimum 5-year follow-up. Three of 13 patients experienced postoperative symptoms of instability but did not undergo further stabilization surgery.

The relationship between posterior shoulder instability and increased glenoid retroversion has been documented. Posterior open wedge glenoid osteotomy is a possible treatment option for patients with increased glenoid retroversion, but outcomes in the literature are limited. Therefore, the purpose of this study was to report the clinical and radiological outcomes following posterior glenoid osteotomy. Patients that underwent posterior glenoid osteotomy for posterior shoulder instability with a GR angle of more than or equal to 10°, and were at least 12 months out from surgery, were included in the study. General data, medical history, and radiographic data such as the pre- and postoperative glenoid retroversion angle were extracted from the patients’ hospital documentation notes. To evaluate the postoperative outcome, the Rowe standard rating scale for shoulder instability and the Oxford shoulder instability score were collected retrospectively. A total of 12 shoulders (11 patients) could be included. The mean pre-operative glenoid retroversion was 23.3° (range 12°–35°) and this reduced significantly (p = 0.003) to a mean of 13° (range 1°–28°) postoperatively. At a mean follow-up of 19.8 months (range 14–36), the median Rowe score was 90 points (range 45–100 points) and the median Oxford instability score was 44 points (range 21–48 points). There were no postoperative re-dislocations or revision surgeries; however, one patient reported signs of recurrent shoulder instability and four asymptomatic glenoid neck fractures occurred. Open wedge posterior glenoid osteotomy provides reliable clinical results with a low rate of clinical failure in a stringently selected patient cohort at short-term follow-up. However, due to the risk of potentially severe complications, we advocate this procedure for experienced shoulder surgeons only, who are familiar with its anatomical and technical considerations.

The purpose of this study was to investigate clinical outcomes following Achilles tendon allograft-augmented latissimus dorsi tendon transfer (LDTT) for the treatment of irreparable posterosuperior rotator cuff tears with a minimum of 2 years post-operative follow-up. We hypothesized that patients would show significant improvement in outcomes scores with a low failure rate. Patients who were treated with Achilles tendon allograft-augmented LDTT for irreparable posterosuperior rotator cuff tears with a minimum follow-up of 2 years were included. Patient-reported outcomes scores, including ASES, QuickDASH, SANE, SF-12 PCS, and satisfaction, were collected pre- and post-operatively. Pre- and post-operative scores were compared with a Wilcoxon test. Revision to reverse total shoulder arthroplasty (RTSA) was considered as failure. Between March 2006 and November 2014, a total of 16 patients with a mean age of 49 years (range 34–57 years) were included. Minimum 2-year outcomes data were available for 14 of the 16 patients (87.5%) with a mean follow-up of 5.5 years (range 2.1–10.5 years). Two patients (12.5%) advanced to RTSA at a mean of 1.1 years following LDTT. Postoperative median subjective outcomes scores improved, but did not reach statistical significance (SF-12 PCS: 35.4–46.4, P = 0.182; ASES: 47.5–69.9, P = 0.209; QuickDASH: 57.9–31.8, P = 0.176; SANE: 40.0–39.5, P = 0.273). Median post-operative patient satisfaction was 5 on a 10-point scale (range 1–10). Patients with irreparable rotator cuff tears treated with Achilles tendon allograft-augmented latissimus dorsi tendon transfer did not experience significant post-operative improvement in patient-reported outcomes. Thus, the use of an additional allograft-augmentation remains questionable. Retrospective case series, level IV.

Economic pressure highlights the critical need for appropriate diagnosis and treatment of various shoulder pathologies since under-diagnosis and under-treatment can result in increased costs to society in the form of disability and lost production. On the other hand, aggressive over-treatment can further inflate already burgeoning health-care costs and potentially harm the patient. Therefore, it is crucial to distinguish the indications between operative and nonoperative management, especially in common shoulder pathologies such as rotator cuff tears, anterior shoulder instability, biceps tendinitis, lesions to the acromioclavicular joint, and proximal humeral fractures. As a result, a detailed analysis of individual risk factors for potential failures should be performed and treatment should be based on individualized care with consideration given to each patient's particular injury pattern, functional demands, and long-term goals.Der zunehmende Kostendruck in der Medizin verstärkt die Notwendigkeit einer rasch zielführenden Diagnose und Therapie verschiedener pathologischer Veränderungen im Bereich der Schulter. Unterversorgte Patienten erhöhen die Kosten für die Gemeinschaft durch längere Ausfallzeiten und damit erniedrigte Produktion, während überzogene Therapien die bereits ausufernden Kosten in der medizinischen Versorgung weiter erhöhen und den Patienten sogar potenziell schädigen können. Deshalb ist es unabdingbar, die Indikationen für operative und konservative Therapien zu kennen und anzuwenden, besonders im Hinblick auf häufige pathologische Veränderungen wie Rotatorenmanschettenläsionen, vordere Schulterinstabilität, Bizepssehnentendinitis, Akromioklavikular Gelenkluxationen und proximale Humerusfrakturen. Grundsätzlich ist es dabei wichtig, individuelle Risikofaktoren für ein Therapieversagen zu erkennen, den Erwartungshorizont des Patienten bezüglich funktionaler Ansprüche und Langzeitziele abzuklären und auch das Verletzungsmuster zu analysieren, um so letztendlich die Therapie individuell an den jeweiligen Patienten anpassen zu können.

Purpose To investigate if patients younger than 50 years old had improved functional outcomes after subpectoral biceps tenodesis (BT) for the treatment of biceps reflection pulley (BRP) lesions at minimum 2-year postoperative follow-up. Methods Patients who had arthroscopically confirmed BRP tears that were treated with subpectoral BT and were at least 2 years out from surgery were included; patients were excluded if they had concomitant reconstructive or reparative procedures at index surgery. Patient-centered outcomes including return to activity, American Shoulder and Elbow Surgeons (ASES), Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH), and Short Form-12 Physical Component Summary (SF-12 PCS) scores, and patient satisfaction were collected. The pre- and postoperative scores were compared with a Wilcoxon test. Failure was defined as revision BT. Results Between January 2006 and July 2014, of 1,184 patients who underwent open subpectoral BT, 14 patients (6 male, 8 female) with mean age 37 (range, 16-49 years) met the inclusion criteria. Minimum 2-year outcomes data were available for all 14 patients (100% follow-up). The mean follow-up was 3.6 ± 1.3 years. There were significant improvements postoperatively for all outcome scores ( P = .017 ASES, P = .002 QuickDASH, P = .003 SF-12 PCS). There was no correlation between age and outcome scores ( P > .05). Median patient satisfaction was 9 of 10. Five patients (36%) reported return to recreational activity with no modifications; 9 (64%) indicated a return to activity with modifications. The 5 patients who returned to recreational activity with no modification had significantly less time from initial injury/onset of symptoms until surgery in comparison with the 9 patients who modified their activity ( P = .028). No complications or reoperations were reported. Conclusions Patients younger than 50 years old with a symptomatic isolated BRP lesion experienced excellent results, high return to recreational activity, little postoperative pain, and high degrees of satisfaction when treated with subpectoral BT. Level of Evidence Level IV, therapeutic case series.

Os acromiale occur frequently in the population and can be a cause of significant shoulder dysfunction and rotator cuff impingement. When symptomatic os acromiale fail conservative management, surgical intervention may become necessary. The purpose of this article is to describe our preferred surgical technique for osteosynthesis of os acromiale using cannulated screws and tension-band wiring.

Chronic anterior shoulder instability due to structural failure of the subscapularis muscle and the anterior capsule is a rare and challenging diagnosis for surgeons to manage because poor-quality capsular, labral, and rotator cuff tissue often limits effective treatment options. If primary repair is not possible because of retraction and poor tissue quality, reconstruction with an allograft or autograft may be the only joint-preserving option. The purpose of this article is to describe a surgical technique for anterior capsular reconstruction using a human acellular dermal allograft for the treatment of irreparable subscapularis tears.

Isolated fractures of the greater tuberosity of the humerus are an uncommon and frequently missed diagnosis. Mistreated and unrecognized, these fractures can cause chronic pain and diminished shoulder range of motion and function. Operative treatment options include open reduction and internal fixation, as well as arthroscopic-assisted reduction and internal fixation. The purpose of this Technical Note is to describe a bridging arthroscopic technique for the treatment of bony avulsions of the supraspinatus tendon.

Background: Osteoarthritis of the sternoclavicular (SC) joint is a rare condition that leads to decreased function and persistent pain, ultimately altering the function of the shoulder and keeping individuals from their desired activities. SC resection in the setting of primary and posttraumatic osteoarthritis is the most common surgical treatment for these patients, but midterm results are lacking. Purpose/Hypothesis: The purpose was to assess the clinical outcomes, pain levels, return to sports rate, and survivorship after open SC joint resection in the setting of painful primary SC joint osteoarthritis. We hypothesized that an SC joint resection of maximum 10 mm would result in a significant improvement in clinical outcomes, decreased pain levels, a high rate of return to sports, and a high survivorship. Study Design: Case series; Level of evidence, 4. Methods: Patients who underwent SC joint resection (maximum 10 mm) by a single surgeon between the years 2006 and 2013 with minimum 5-year follow-up were reviewed. The following clinical outcomes were collected prospectively during this time period: 12-Item Short Form Health Survey Physical Component Score (SF-12 PCS), American Shoulder and Elbow Surgeons (ASES) score, Single Assessment Numerical Evaluation (SANE) score, Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score, and patient satisfaction. Return to sports and pain were assessed through use of a customized questionnaire. Survivorship of SC joint resection was defined as not requiring further surgery on the affected joint. Results: A total of 21 SC joints were treated with resection of the medial clavicle and intra-articular disk and capsulorrhaphy for SC joint osteoarthritis in 19 patients with a mean age of 39.4 years (range, 12.5-66.7 years). At minimum 5-year follow-up, 19 SC joint resections were assessed in 16 of 19 patients (84%) with a mean follow-up of 6.7 years (range, 5.0-10.4 years). All outcome scores improved significantly from pre- to postoperative assessments: ASES (from 54 to 90.5; P = .003), SANE (from 61.8 to 90.4; P = .004), QuickDASH (from 43.1 to 13.8; P = .004), and SF-12 PCS (from 39.8 to 51.3; P = .004). Median satisfaction with surgical outcomes was 9 (range, 2-10), and pain levels improved from a score of 8 out of 10 to 3 out of 10 (scale of 0 to 10 with 0 being pain free and 10 worst possible pain). Of the 13 patients who answered the optional sports participation question, 13 (100%) patients had participated in sports before their injury. A total of 14 patients answered the question on sports participation after injury, with 12 (86%) indicating successful return to sports. Pain at its worst ( P = .003) and pain with competition ( P = .017) significantly decreased pre- to postoperatively. Resection survivorship at final follow-up was 84.2% at 5 years. We found that 3 patients (15%) had recurrent SC joint pain and were treated with revision surgery. Conclusion: Open SC resection arthroplasty with capsulorrhaphy in the setting of pain for SC osteoarthritis results in significant improvement in clinical outcomes, patient satisfaction, return to sports, and pain reduction at minimum 5-year follow-up.

INTRODUCTION Despite the widespread use of arthroscopic double-row transosseous-equivalent (TOE) rotator cuff repair (RCR) techniques, midterm outcome data are limited. The purpose of this article was to assess midterm clinical outcomes of patients following arthroscopic TOE RCR using either a knotless tape bridge (TB) repair or knotted suture bridge (SB) repair technique. We hypothesized that there would be significant improvements in patient-reported outcomes with TOE RCR that would be durable over time. We also hypothesized that the knotless TB technique would yield equivalent clinical results to the knotted SB technique, but that there would be differences in retear types between the two TOE techniques. METHODS Patients included were a minimum of 5 years from an index arthroscopic double-row TOE repair using either a knotless TB or knotted SB technique for one, two, or three tendon full-thickness rotator cuff tears involving the supraspinatus tendon. Preoperative and postoperative American Shoulder and Elbow Surgeons, Short-Form 12 Physical Component Summary, Quick Disabilities of the Arm, Shoulder, and Hand, Single Assessment Numeric Evaluation, and satisfaction scores were collected. Scores were also stratified and compared based on primary and revision repair, tear location, and tear chronicity. Outcomes between techniques were contrasted, and survivorship analysis was conducted, with failure defined as progression to revision surgery. RESULTS One-hundred ninety-two shoulders were included with a mean follow-up of 6.6 years (range, 5.0 to 11.0 years). Fifteen shoulders (7.8%) underwent revision cuff repair. All scores improved significantly for TB repair (P < 0.001). For SB repair, all scores improved, but only American Shoulder and Elbow Surgeons and Short-Form 12 Physical Component Summary scores (P < 0.05) demonstrated statistical significance. No statistically significant differences were found between the repair techniques when stratified by primary and revision repairs, tear location, or chronicity. Postoperative clinical survivorship was 96.6% and 93.6% for knotted SB repairs and 96.7% and 93.9% for knotless TB repairs at 2 and 5 years, respectively. CONCLUSION TOE RCR results in significant clinical improvement and excellent survivorship at a minimum of 5 years of follow-up, using either knotted SB or knotless TB repair techniques in primary and revision cases and in small and large tears. Equivalent results were obtained with both TOE techniques. Patients undergoing repair with a TOE showed significant improvements in patient-reported outcomes that were durable at a minimum of 5 years postoperatively.

Clavicle fractures are among the most common fractures occurring in the general population, and the vast majority are localized in the midshaft portion of the bone. Management of midshaft clavicle fractures remains controversial. Although many can be managed nonoperatively, certain patient populations and fracture patterns, such as completely displaced and shortened fractures, are at risk of less optimal outcomes with nonoperative management; surgical intervention should be considered in such cases. The purpose of this article is to demonstrate our technique of midshaft clavicle fixation using minimally invasive intramedullary fixation.

The large excursion of the latissimus dorsi muscle makes it an ideal candidate for tendon transfer as a salvage procedure in cases of massive and irreparable postero-superior rotator cuff tears in young and active patients. The tendon of the latissimus dorsi is transferred from its insertion on the bicipital groove to the postero-superior greater tuberosity, allowing the transferred tendon to close the postero-superior rotator cuff defect and act as a humeral head depressor. To avoid excessive tension at the tendon-bone-interface, an allograft patch can be used to extend the harvested tendon. However, as a biofeedback program needs to be initiated postoperatively to achieve good outcomes, patients with limited physical coordination abilities should not be treated with latissimus dorsi tendon transfer. Overall, long-term results have been satisfactory.

In patients with irreparable tears of the subscapularis tendon, the transfer of the pectoralis major tendon is a viable treatment option. The transfer of the upper 2/3 of the pectoralis major tendon to the humeral head is used for irreparable tears of the upper part of the subscapularis tendon and recreates the balance of the shoulder force couple, thus mimicking the natural function of the subscapularis and promoting pain relief. In case of a complete and irreparable rupture of the subscapularis tendon, the pectoralis major transfer can be combined with an additional transfer of the teres major tendon.

While extra-articular ligaments such as the medial collateral ligament (MCL) benefit from the absence of adverse effects from synovial fluid and therefore rarely encounter issues of healing absent of intervention, intra-articular ligament injuries, for instance an anterior cruciate ligament (ACL) tear, requires biological intervention to assist with native healing due to a lack of intrinsic healing potential. To enhance healing capacities, different types of biologics such as growth factors and stem cells can be applied. The intended goals for the use of biologics in ligament injuries are primarily geared toward accelerating healing while minimizing the risk of a reinjury. While the results of preclinical and basic science studies are promising, to date there is insufficient evidence to suggest that the use of biologics provides any significant clinical benefit.

In patients with irreparable tears of the subscapularis tendon, reconstruction with an allo- or autograft may be a viable therapeutic option. However, the postoperative results of published techniques show varying rates of success. Using a human acellular dermal allograft for an anterior capsule reconstruction (ACR) may offer additional benefits such as superior mechanical strength compared to smaller and thinner tendon allografts used in the past. The implantation of an allograft replaces the torn subscapularis tendon’s role as the anterior joint stabilizer, thus preventing the humeral head from migrating anteriorly by acting as a static restraint. This surgery alters shoulder biomechanics as the graft acts as a static restraint, thereby centering the humeral head during active movement, preventing anterior escape, and thus leading to improved function and pain relief.

Tightness or contracture of the pectoralis minor muscle can cause significant scapular dysfunction and is typically seen in patients with scapular dyskinesis and abnormal scapular protraction. When nonoperative treatment in these patients has failed, pectoralis tenotomy aims to resect the pectoralis minor tendon from the medial aspect of the coracoid process in order to decrease the force on the scapula, thereby improving scapular dynamics.

The postero-superior rotator cuff is the most common location for full-thickness rotator cuff tears and leads to a significant amount of shoulder pain and disability annually. Advancements in arthroscopy and imaging have permitted improved identification of these tear patterns. Tears may be categorized as crescent, U-shaped, L-shaped, reverse-L-shaped or massive, contracted, immobile tears. The specific tear pattern is important as each pattern has a recommended treatment method based on biomechanical considerations.

In cases of massive irreparable supraspinatus tendon or combined supraspinatus / infraspinatus tendon tears, reverse total shoulder replacement can offer good results. However, in young and active patients with these types of irreparable posterosuperior rotator cuff tears limited prosthetic implant longevity and activity restrictions for high-impact activities make reverse total shoulder arthroplasty a less desirable option. Arthroscopic superior capsule reconstruction (ASCR) is an alternative technique for this pathology with advantages of minimal invasiveness, better approximation of the native anatomy, and the potential for easier future surgical revisions. The implantation of a graft replaces the torn superior rotator cuff tendon’s role as the superior capsule, thus preventing the humeral head from migrating superiorly by acting as a static restraint. This surgery alters shoulder sbiomechanics as the graft acts as a “checkrein,” re-centering the humeral head during abduction and forward flexion, preventing superior escape, and leading to imporved function and pain relief.

To compare sagittal and coronal tibial slopes between anterior cruciate ligament (ACL) injured subjects with and without posterolateral meniscus root tear (PLRT). A chart review was conducted to identify patients with isolated ACL tears and patients with an associated PLRT. Patients with other concomitant injuries and patients who underwent surgery > 6 months after the injury were excluded. Magnetic resonance image data were used to compare the medial and lateral sagittal tibial slope (MTS and LTS), lateral-to-medial slope asymmetry (LTS–MTS), and coronal slope of the tibial plateau between both groups. Mean LTS and standard deviation (SD) of the control group were calculated, and a value of > mean + 1 SD was considered an abnormal LTS. Interobserver reproducibility was assessed by calculating interclass correlation coefficients (ICCs) of measurements independently obtained by two reviewers. Fifty-nine patients met the in- and exclusion criteria. Thirty nine (66%) had an isolated ACL tear and 20 (34%) had an associated PLRT. Interrater ICCs for LTS, MTS, and coronal slope were 0.930, 0.884 and 0.825, respectively, representing good to excellent interobserver reproducibility. Patients with a PLRT had significantly steeper LTS (8.0 ± 3.2 vs. 4.0 ± 2.0; p

Background: Patients are staying active longer and expect to return to sports or continue participating in recreational activities after total shoulder arthroplasty (TSA) for primary glenohumeral osteoarthritis. Purpose/Hypothesis: The purpose of this study was to assess the ability of patients to return to recreational sports following TSA. We hypothesized that TSA would allow a high rate of return to recreational sports. Study Design: Case series; Level of evidence, 4. Methods: All patients who underwent primary TSA by a single surgeon and were at least 2 years out from surgery were included and were studied for their ability to return to recreational activity following surgery between December 2005 and January 2015. Patient-reported outcomes were obtained, including the 12-Item Short Form Health Survey–Physical Component Summary (SF-12 PCS); Single Assessment Numeric Evaluation (SANE); Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire; American Shoulder and Elbow Surgeons (ASES) score; and satisfaction scores (10-point scale), preoperatively and at a minimum of 2 years postoperatively. Return-to-sport rates were assessed using a standardized patient-reported outcome questionnaire. Results: A total of 165 patients (186 shoulders) that received TSA met the inclusion criteria for the study. Preoperatively, 139 patients (157 shoulders) were involved in recreational sports; 16 (8.6%) shoulders required additional surgical intervention after the index TSA procedure. A significant postoperative increase was noted in the mean ASES (from 48.3 to 87.0; P < .001), QuickDASH (from 41.0 to 15.8; P < .001), SANE (from 49.1 to 81.2; P < .001), and SF-12 PCS scores (from 38.6 to 48.9; P = .004). Of the 157 shoulders in the recreational sports cohort, responses to the survey examining recreational sporting activities after surgery were available for 112 shoulders. The overall rate of return to sport or recreational activity following TSA was 93.7% (105/112 shoulders). The rate of return to recreational sporting activity equal to or better than the preinjury level was 69.7% (78/112 shoulders), while 6.3% (7/112 shoulders) of our cohort reported that they were unable to compete in recreational sports following TSA. Of the patients who participated in predominantly upper extremity sporting activities after TSA, 49% had to modify their postoperative recreational sporting activity because of lifestyle change, pain, weakness, or decreased range of motion. Conclusion: Patients undergoing TSA showed excellent postoperative improvement in their outcome scores, satisfaction, and return to athletic activities. Despite the expected decrease in activity levels with the slow progression of osteoarthritis over time until TSA was performed, almost 94% of patients successfully returned to various recreational sporting activities postoperatively. This study showed that return to recreational sports can be achieved at participation levels that are comparable with preoperative levels, but athletes in some sports such as tennis or swimming, which require more intense levels of exercise, are less likely to return to the same participation levels.

Background: Septic arthritis (SA) of the knee after anterior cruciate ligament reconstruction (ACLR) is a rare but potentially devastating condition. In certain cases, graft removal becomes necessary. Purpose: To evaluate clinical, subjective, and radiologic outcomes of patients with SA after ACLR and assess whether graft retention has superior clinical results as compared with graft removal. Study Design: Cohort study; Level of evidence, 3. Methods: All patients who were at least 12 months out from arthroscopic treatment of SA after isolated ACLR at our institution were eligible for inclusion. Patients were categorized into 2 groups: group 1, patients with initial graft retention; group 2, patients with initial graft removal. Group 2 was subdivided into 2 groups: group 2a, patients with graft reimplantation; group 2b, patients without graft reimplantation. Objective and subjective assessments were obtained at follow-up, including the International Knee Documentation Committee (IKDC) knee examination form, KT-1000 arthrometer measurements, WOMAC (Western Ontario and McMaster Universities Osteoarthritis Index) score, Lysholm score, and IKDC subjective evaluation. Radiologic assessment was performed with pre- and postoperative magnetic resonance imaging. Results: Of the 41 patients included, 33 (81%) were available for follow-up at a mean ± SD 54.7 ± 24.4 months at an age of 28.4 ± 9.3 years. When compared with patients from group 2 (n = 12), patients from group 1 (n = 21) obtained significantly better results on the objective IKDC score (normal or nearly normal: group 1, 66.6%; group 2, 36.4%; P = .047) and KT-1000 measurements (group 1, 1.3 ± 1.0 mm; group 2, 2.9 ± 1.5 mm; P = .005). Group 1 also scored better than group 2 on the Lysholm ( P = .007), IKDC subjective ( P = .011), and WOMAC ( P = .069) measures. Between groups 2a (n = 4) and 2b (n = 8), no significant differences in outcomes could be detected ( P values, .307-.705), although patients with anterior cruciate ligament graft reimplantation showed a clear tendency toward better results in objective and not subjective parameters. Magnetic resonance imaging evaluation showed higher rates of cartilage damage and meniscal tears among patients with graft resection versus graft retention. Conclusion: Patients with graft retention showed superior postoperative results when compared with patients who underwent initial graft resection, although subanalysis showed comparable outcomes between graft retention and reimplantation. Thus, while graft-retaining protocols should have the highest priority in the treatment of SA after ACLR, graft reimplantation should be performed in cases where graft resection becomes necessary, to avoid future cartilage and meniscal lesions. Finally, further studies with larger numbers of patients are needed to gain a better understanding of the outcomes of patients with SA after ACLR.

Objectives: Rotator cuff tears lead to significant morbidity due to pain and decreased function. Despite the prevalence of cuff repairs, mid-term outcomes have been scarcely reported. The purpose of this study is to report minimum 5-year outcomes and clinical survivorship after double-row rotator cuff repair for full-thickness supraspinatus tendon tears. Methods: Patients at least five years out from arthroscopic double-row repair for a full-thickness cuff tear involving the supraspinatus tendon were included. Pre- and postoperative ASES, SF-12 PCS, QuickDASH, SANE, and satisfaction scores were collected. The relationship between outcomes and (1) tear chronicity, (2) number of tendons involved, (3) type of repair, and (4) primary versus revision procedure, was also evaluated. Kaplan-Meier survivorship analysis was conducted defining failures as progression to revision rotator cuff surgery. Results: From November 2005 to February 2012, a total of 189 shoulders were eligible for inclusion. Fifteen shoulders (7.9%) underwent revision rotator cuff repair and were considered failures. Outcomes data were reported at a mean follow-up of 6.6 (range, 5.0-11.0) years. All outcome scores significantly improved from pre- to postoperative time point, including mean ASES (57.9 to 92.9, P < 0.001), SF-12 PCS (43.4 to 52.0, P < 0.001), QuickDASH (35.2 to 10.5, P < 0.001), and SANE scores (61.5 to 86.5, P < 0.001). Acute tears demonstrated significantly better ASES and SANE scores than chronic tears (ASES 95.1 ± 8.9 versus 91.7 ± 11.2, P = 0.025; SANE 89.6 ± 19.9 versus 85.7 ± 21.3, P = 0.042). No other analyzed variable had a significant association with outcomes scores ( P > 0.05). Survivorship analysis demonstrated a postoperative clinical survivorship of the repair of 96.5% at two years and 93.8% at five years (Figure 1). Conclusion: Patients can expect excellent clinical outcomes and a low failure rate following arthroscopic double-row repair of full-thickness supraspinatus tears at mid-term follow-up. The repair of acute tears and primary repairs were associated with better postoperative outcomes.

To prospectively evaluate the clinical and radiographic outcomes and survivorship at 2 and 5 years after isolated contemporary patellofemoral inlay arthroplasty. Thirty-four patients were prospectively enrolled in the study and were evaluated preoperatively and at 2 and 5 years postoperatively. Clinical outcomes included the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score and the visual analogue scale (VAS) for pain. Kellgren-Lawrence grading was used to assess the progression of tibiofemoral osteoarthritis and the Caton-Deschamps Index to determine patellar height. A Kaplan–Meier survival analysis was used to investigate the implant survivorship. Preoperative patient characteristics were compared among failures and success to determine potential risk factors and patient satisfaction was rated postoperatively. Five of the 34 patients were lost to follow-up resulting in a final follow-up rate of 86%. The total WOMAC subscores of pain and function and the VAS Pain improved significantly at 2- and 5-years, with no significant difference between the two time points. The WOMAC stiffness subscale reached significant improvement at 2-year follow-up alone. No significant progressions of tibiofemoral arthritis or changes in patellar height were observed. A total of six patients (17.1%) failed leaving a survival rate of 91% after 2 years and 83% after 5 years. The main cause for postoperative failure was persistent knee pain; however, no significant preoperative risk factor in patient characteristics could be identified. Patellofemoral inlay arthroplasty shows high patient satisfaction with significant improvement in knee function and pain relief after mid-term follow-up with no radiographic progression of tibiofemoral OA. Prospective case series, Level III.

The authors of this chapter review the anatomy, classification, indications, imaging, surgical techniques, complications and post-operative rehabilitation of distal clavicle fractures. Advanced arthroscopic techniques and open reduction internal fixation (ORIF) are discussed for high-risk young athletes.

Background:Superior capsular reconstruction (SCR) was recently introduced as a treatment for irreparable superior rotator cuff tears in younger patients.Purpose/Hypothesis:The purpose was to assess the biomechanical strength of 3 methods for fixation of the graft to the glenoid for SCR. It was hypothesized that a 4-anchor technique would provide greater load to failure than 3-anchor techniques.Study Design:Controlled laboratory study.Methods:Thirty-six cadaveric specimens were randomized into 3 groups of previously established glenoid-side graft fixation techniques: (1) three 3.5-mm knotless screw-in anchors, (2) three 3.0-mm knotless push-in anchors, and (3) a 4-anchor hybrid construct with two 3.0-mm knotted push-in anchors and two 2.9-mm knotless push-in anchors. The repairs were cyclically loaded at 0.5 Hz from 10 to 200 N, then pulled to failure. Elongation, stiffness, maximum load at failure, and mode of failure were recorded and calculated.Results:There were no significant differences in graft elongation or stiffness among the 3 techniques ( P > .37 and P > .26, respectively). Maximum load to failure was significantly greater in technique 1 (mean ± SD, 427.85 ± 119.70 N) than technique 3 (319.5 ± 57.60 N) ( P = 0.024). There were no significant differences in load to failure between techniques 1 and 2 or between techniques 2 and 3.Conclusion:Glenoid-side graft fixation with 3 threaded 3.5-mm suture anchors showed a significant superior pull-out strength when compared with a 4-anchor hybrid technique and thus might be recommended in SCR for patients with irreparable superior rotator cuff tears to achieve maximum stability.Clinical Relevance:SCR presents a novel alternative for treatment of irreparable superior rotator cuff tears in younger patients. Glenoid fixation is essential to provide adequate fixation of the graft to prevent the humeral head from rising and to restore normal biomechanics.

Recurrent instability is a frequent complication following arthroscopic Bankart repair. The purpose of this study was to investigate risk factors for poor patient-reported clinical outcome scores and failure rates.Patients who underwent arthroscopic Bankart repair at least 2 years earlier were included. Preoperative and postoperative Single Assessment Numeric Evaluation; Quick Disabilities of the Arm, Shoulder and Hand; American Shoulder and Elbow Surgeons; and satisfaction scores were collected. The relationship of the following factors with outcomes and failure rates was assessed: (1) previous arthroscopic stabilization, (2) 3 or more dislocations prior to surgery, (3) glenoid labral articular disruption (GLAD) lesion, (4) concurrent superior labral anterior-to-posterior tear repair, and (5) concurrent biceps tenodesis.The study included 72 patients with a median age of 23 years (range, 14-49 years). Subsequent revision was required in 9 (12.5%); 1 additional patient (1.4%) had recurrent dislocation. Outcome data were available at a median follow-up of 3 years (range, 2-9 years). All scores significantly improved from preoperatively to postoperatively (P .05); the mean patient satisfaction score was 9, with a median of 10 (range, 1-10). None of the analyzed factors were associated with worse postoperative outcome scores. GLAD lesions were significantly associated with a higher rate of failure (P = .007). No other analyzed factors had a significant association with failure rates (P .05).Patients with arthroscopic Bankart repair for traumatic anteroinferior shoulder instability had excellent outcomes, even in the context of previous arthroscopic stabilization surgery, 3 or more dislocations prior to surgery, concurrent superior labral anterior-to-posterior tear repair, or concurrent biceps tenodesis. However, GLAD lesions were associated with higher rates of failure, and the presence of a GLAD lesion may herald the presence of changes in the articular version or other as-yet-undetermined factors that could predispose patients to failure.

Humeral avulsion of the glenohumeral ligament (HAGL) is a lesion associated with anterior shoulder instability. Although uncommon, HAGL lesions are a significant contributor to shoulder pain and dysfunction and, if missed, can even be a cause of failed Bankart repair. HAGL lesions should generally be repaired surgically; however, given their low prevalence, there is no consensus on the optimal surgical approach. The purpose of this Technical Note is to describe our preferred surgical technique for the fixation of an HAGL lesion using an all-arthroscopic approach and a knotless suture anchor construct.

Purpose To perform a quantitative anatomic evaluation of the (1) coracoid process, specifically the attachment sites of the conjoint tendon, the pectoralis minor, the coracoacromial ligament (CAL), and the coracoclavicular (CC) ligaments in relation to pertinent osseous and soft tissue landmarks; (2) CC ligaments' attachments on the clavicle; and (3) CAL attachment on the acromion in relation to surgically relevant anatomic landmarks to assist in planning of the Latarjet procedure, acromioclavicular (AC) joint reconstructions, and CAL resection distances avoiding iatrogenic injury to surrounding structures. Methods Ten nonpaired fresh-frozen human cadaveric shoulders (mean age 52 years, range 33-64 years) were included in this study. A 3-dimensional coordinate measuring device was used to quantify the location of pertinent bony landmarks and soft tissue attachment areas. The ligament and tendon attachment perimeters and center points on the coracoid, clavicle, and acromion were identified and subsequently dissected off the bone. Coordinates of points along the perimeters of attachment sites were used to calculate areas, whereas coordinates of center points were used to determine distances between surgically relevant attachment sites and pertinent bony landmarks. Results The CAL had a single consistent acromial attachment (mean area 77 mm [51.9, 102.2]) and then bifurcated into 2 bundles, anterior and posterior, that separately inserted on the lateral aspect of the coracoid. The footprint areas were 54.4 mm 2 [31.7, 77.2] and 30.6 mm 2 [23.4, 37.7] for the anterior and posterior CAL bundles, respectively. These anterior and posterior bundles attached 10.6 mm [8.4, 12.9] and 24.8 mm [12.3, 27.4] medial and proximal to the apex of the coracoid process, respectively. The minimum distance between the coracoid apex and the trapezoid ligament was 25.1 mm [22.1, 28.1] and was noted to be different in males (28.1 mm [25.1; 31.2]) and females (22.0 mm [18.2, 25.9]). The most lateral insertion of the CC ligaments on the clavicle the AC joint was 15.7 mm [13.1, 18.3]. The distance between the most medial to the most lateral point of the CC ligaments on the clavicle was 25.6 mm [22.3, 28.9], which accounted for 18.2% [15.8, 20.6] of the clavicle length. Conclusions In contrast to previous findings, 2 different coracoid attachments (anterior and posterior bundles) of the CAL were consistently identified in all specimens. Moreover, a coracoid osteotomy for a bone graft for the Latarjet procedure should be performed at less than 28.1/22 mm from the apex of the coracoid in male/female patients, respectively. The CC ligaments' attachments on the clavicle were located 15.7 mm from the AC joint, which should be considered for reconstruction. Clinical Relevance During the Latarjet technique, to maintain the integrity of the CC ligaments, precise knowledge of differences between male and female anatomy is necessary during a coracoid osteotomy. Furthermore, when reconstructing the AC joint, the distance from the lateral aspect of the clavicle and the size of the attachments areas should be considered to better replicate the native anatomy.

Objectives: Biceps Reflection Pulley (BRP) lesion is a common generator of anterior shoulder pain and cause of biceps tendon instability. The purposes of this study were (1) to investigate if patients younger than 50 years had improved functional outcomes following open subpectoral biceps tenodesis (BT) for treatment of an isolated BRP lesion with a minimum follow-up of 2-years, and (2) to determine whether a correlation exists between patient age and outcomes scores. It was hypothesized that subpectoral BT would result in reduced pain, improved functional outcomes, and a high return-to-activity rate and that there would be no association between patient age and outcomes scores. Methods: This was an IRB-approved study with retrospective review of prospectively-collected data. All patients who had arthroscopically confirmed isolated BRP lesion treated with open subpectoral biceps tenodesis were at least 2 years out from surgery were included in the study. Patients with additional surgery on the index shoulder were excluded from the study. ASES (pain and function), QuickDASH, and SF-12 scores were collected pre- and postoperatively. Postoperative satisfaction (10-point scale) was also collected. The pre- and postoperative scores of each patient were compared with a Wilcoxon-test, and association between patient age and outcomes scores were investigated with a Spearman correlation test. Further, patient return-to-activity was evaluated by questionnaire. Failure was defined as revision surgery of the biceps tenodesis. Results: 14 shoulders in 14 patients (6 male, 8 female) with a mean age of 37 ± 8.9 years met the inclusion criteria. Minimum 2-year outcomes data were available for 13 (93%) shoulders. The mean follow-up time was 3.6 ± 1.3 years. There were significant improvements postoperatively for all outcome scores (p0.05). Overall, median patient satisfaction was 9 out of 10 (range 3-10). Of 14 patients who answered the “return-to-activity” questions, 5 patients () reported return to activity with no modification; 9 patients reported return to activity with modifications. The 5 patients who returned to activity with no modification had significantly less time from initial injury/onset of symptoms until surgery in comparison to the 9 patients who modified their activity (p

Purpose The purpose of this study was to evaluate outcomes following open subpectoral biceps tenodesis for the treatment of isolated type II SLAP lesions in patients 45 years of age or younger and evaluate the rate of return to sport. Methods All patients included in the study were at least 2 years out from open subpectoral biceps tenodesis for treatment of an isolated type II SLAP lesion and were treated between December 2007 and March 2015. All patients older than 45, those who had prior surgery on the index shoulder, and those who had any concomitant reconstructive shoulder procedures were excluded. American Shoulder and Elbow Surgeons (ASES), Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH), Single Assessment Numeric Evaluation (SANE), and Short-Form 12 Physical Component Summary (SF-12 PCS) scores were collected pre- and postoperatively along with postoperative patient satisfaction. Patient return to sport was evaluated by questionnaire. Results Twenty patients with a mean age of 38 years (range 21-45) were included, of which 16 were available for follow-up. There was significant improvement in median pre- to postoperative outcome scores (ASES, 66-94 points, P = .001; QuickDASH, 31-8, P = .003; SANE, 60-92, P = .001, SF-12 PCS, 41-52 points, P = .002), with a median patient satisfaction of 8.5 points (range 1-10) at a mean follow-up of 3.4 years (range, 2.0-6.3 years). At final follow-up, all patients had returned to sport, with 73% of patients indicating a return to their previous or comparable level of sports. Subgroup analysis showed 80% of overhead athletes returned to the same or a comparable level postoperatively. Conclusions This study suggests that young patients around their 30s participating in sport at a recreational level may benefit from open subpectoral biceps tenodesis for a primary isolated SLAP II tear and would experience excellent outcomes, high satisfaction, and a high rate of return to sport.

Purpose To determine the exact value of side-to-side difference (SSD) in heel height that was associated with combined anterior cruciate ligament (ACL) and fibular collateral ligament (FCL) tears (compared with an isolated ACL tear) and determine the clinical utility of heel height SSD in the assessment of this injury pattern. Methods Two patient groups were identified: (1) patients with isolated ACL tears and (2) patients with combined ACL-FCL tears but without additional collateral or cruciate ligament injuries. Determination of the amount of the heel height SSD was determined during the outpatient clinic visit. Receiver operator characteristic curves were used to evaluate the accuracy of diagnostic tests by plotting the true-positive (sensitivity) rate against the false-positive (1-specificity) rate at various thresholds. In addition, magnetic resonance imaging (MRI) reports were reviewed to calculate the sensitivity of MRI for the detection of FCL injury. MRI sensitivity was then compared with the sensitivity of the heel height examination. Results One hundred and fifty-eight patients (71 men, 87 women) in the isolated ACL tear patient group and 117 patients (60 men, 57 women) in the combined ACL-FCL tear patient group were reviewed. A 3-cm or greater SSD was found in 13 of the 158 (8.2%) isolated ACL tear patients and 84 of the 117 (72%) ACL-FCL tear patients. The sensitivity, specificity, positive predictive value, and negative predictive value of the heel height test were 72%, 92%, 86%, and 86%, respectively. The area under the receiver operator characteristic curve was found to be 0.876. After review of all preoperative MRI musculoskeletal radiology reports for patients in the ACL-FCL patient group, a sensitivity of 48% was found. Conclusions The clinical heel height test resulted in high sensitivity and excellent specificity for the diagnosis of combined ACL-FCL tears compared with the sensitivity and specificity of the MRI detection of FCL injury. The information presented in the current study will improve diagnostic ability through a simple physical examination and avoid missed injuries that are known to compromise surgical outcomes.

Although uncommon, rotator cuff tears that occur medially at the musculotendinous junction can result from acute trauma, anatomic force imbalance, or medial row cuff failure following a previous rotator cuff repair. The quality of the torn muscle and tendon along with the length of the remnant tendon stump should be considered before deciding on the most appropriate repair technique. When muscle and tendon quality are sufficient, the tear can often be repaired directly to the remnant tendon stump and compressed onto the greater tuberosity. If the remnant tendon stump is degenerative, of insufficient length, or lacks tendon in which to place sutures, an allograft patch can be used to augment the repair. When the quality of the remaining muscle and tendon are poor or when the muscle is retracted too far medially and is nonmobile, a bridging technique such as superior capsule reconstruction is preferable. The purpose of this report is to (1) highlight that medial cuff failure can occur both primarily and after previous repair; (2) define and classify the 3 major tear patterns that are encountered, and (3) describe the authors' preferred techniques for medial cuff repair that specifically address each of the major tear patterns.
