While there has been increased attention to the use of reverse total shoulder arthroplasty (RTSA) to treat rotator cuff intact glenohumeral osteoarthritis (RCIOA) for older age groups, there has not been as precise an assessment of the differences in utilization for female vs. male patients or in specific age groups. Our purpose was to determine if differences existed in the utilization of shoulder arthroplasty to treat RCIOA based on gender and age in North America. Anatomic total shoulder arthroplasty (ATSA) and RTSA cases were queried from the American Academy of Orthopaedic Surgeons Shoulder and Elbow Registry between January 2015 and December 2021. Cases were included if they had a diagnosis of RCIOA, defined by the International Classification of Diseases-10 codes M19.011, M19.012, and M19.019. Cases were stratified by procedure, age, gender, and year of surgery. Chi-square and Fisher's exact tests were calculated to assess the associations between procedure type and patient demographics. There were 2748 (48.06%) ATSA and 2970 (51.94%) RTSA procedures reported to the American Academy of Orthopaedic Surgeons Shoulder and Elbow Registry. There was a significant relationship between procedure type and age group (P <.001) in that ATSA was utilized more frequently than RTSA for patients ages <70 years old, and this relationship reversed for ages ≥ 70 years old. Female patients were more likely to receive RTSA (P <.001). When looking at the relationship between procedure type and gender by age group, both genders were more likely to receive ATSA compared to RTSA for age groups 50-59 and 60-69 (P =.0097 and P =.0005, respectively) but not for other age groups. For patients ≥ 70 years old, both females and males were more likely to receive RTSA, but this relationship did not reach statistical significance (P =.1094). For both genders and ages ≥ 70 years old, there was a significant relationship between year and procedure type (P <.0001) in that RTSA was more commonly utilized in 2017 and onward. When assessing patients with RCIOA, the use of ATSA and RTSA was similar, but for patients 50 to 69 years old, for both genders, the use of ATSA was greater. Although RTSA was more commonly used for both genders in the ≥ 70 years old population, this difference was not significant. Interestingly, for both genders, ages ≥ 70 years old, RTSA was significantly more utilized from 2017 onward. This analysis highlights the influence of age and gender in use of ATSA and RTSA.

Background: Return-to-play (RTP) assessment after anterior cruciate ligament reconstruction (ACLR) rarely includes hip strength. Hypothesis: It was hypothesized that (1) patients after ACLR will have weaker hip abduction (AB) and adduction (AD) strength compared with the contralateral limb, with larger deficits in women, (2) there will be a correlation between hip and thigh strength ratios and patient-reported outcomes (PROs), and (3) hip AB and AD strength will improve over time. Study Design: Descriptive laboratory study. Methods: Included were 140 patients (74 male, 66 female; mean age, 24.16 ± 10.82 years) who underwent RTP assessment at 6.1 ± 1.6 months after ACLR; 86 patients underwent a second assessment at 8.2 ± 2.2 months. Hip AB/AD and knee extension/flexion isometric strength were measured and normalized to body mass, and PRO scores were collected. Strength ratios (hip vs thigh), limb differences (injured vs uninjured), sex-based differences, and relationships between strength ratios and PROs were determined. Results: Hip AB strength was weaker on the ACLR limb (ACLR vs contralateral: 1.85 ± 0.49 vs 1.89 ± 0.48 N·m/kg; P <.001) and hip AD torque was stronger (ACLR vs contralateral: 1.80 ± 0.51 vs 1.76 ± 0.52 N·m/kg; P =.004), with no sex-by-limb interaction found. Lower hip-to-thigh strength ratios of the ACLR limb were correlated with higher PRO scores (r = −0.17 to −0.25). Over time, hip AB strength increased in the ACLR limb more than in the contralateral limb (P =.01); however, the ACLR limb remained weaker in hip AB at visit 2 (ACLR vs contralateral: 1.88 ± 0.46 vs 1.91 ± 0.45 N·m/kg; P =.04). In both limbs, hip AD strength was greater at visit 2 than visit 1 (ACLR: 1.82 ± 0.48 vs 1.70 ± 0.48 N·m/kg; contralateral: 1.76 ± 0.47 vs 1.67 ± 0.47 N·m/kg; P <.01 for both). Conclusion: The ACLR limb had weaker hip AB and stronger AD compared with the contralateral limb at initial assessment. Hip muscle strength recovery was not influenced by sex. Hip strength and symmetry improved over the course of rehabilitation. Although strength differences across limbs were minor, the clinical importance of these differences is still unknown. Clinical Relevance: The evidence provided highlights the need to integrate hip strength into RTP assessments to identify hip strength deficits that may increase reinjury or lead to poor long-term outcomes.

After the popularity of reverse total shoulder arthroplasty (rTSA) in Europe, the United States Food and Drug Administration (FDA) cleared the Delta rTSA system (DePuy Inc., Warsaw, IN, USA) for use in late 2003. The original FDA approved indications for rTSA in the United States were limited to a "Grossly rotator cuff deficient joint with severe arthropathy or a previous failed joint replacement with a grossly rotator cuff deficient joint." Surgeons began to use rTSA for many off-label indications: osteoarthritis (OA) without rotator cuff tear (RCT), massive RCT without OA, proximal humerus fractures (PHFx), inflammatory arthritis (IA), and chronic glenohumeral joint dislocation (GHJD). Since 2006, The FDA has approved PHFx as an indication for some but not all reverse implants. The purpose of this study is to evaluate the trends in off-label rTSA use in the American Academy of Orthopaedic Surgeons Shoulder and Elbow Registry (AAOS-SER). All rTSA procedures reported to the AAOS-SER from January 2015 to March 2021 were analyzed. Diagnoses associated with the use of rTSA including RCT arthropathy, OA without RCT, RCT without OA, PHFx, IA, and GHJD were evaluated, and trends were assessed over the data collection period. At the time of data analysis the AAOS-SER contained 3850 cases of rTSA. Only 24.4% of rTSA surgeries were performed for original on-label use (RCT arthropathy). Off-label use of rTSA was seen in 75.6% of cases. When reviewing those rTSA done off-label, the majority (41.4%) were done for OA without RCT. Other off-label rTSA use included 15.1% for RCT without OA, 13% potentially off-label for PHFx, 4.6% for IA, and 1.6% for GHJD. Proportionally, off-label use is increasing over time while on-label use is decreasing. In the AAOS-SER, the majority of rTSA were performed for indications originally considered off-label by the FDA-a trend increasing over time. Some implant manufacturers have expanded indications for rTSA without providing clinical data to support changing FDA approved indications for use. The incremental expansion of indications for use without supportive data, a practice known as predicate creep, is occurring with rTSA. Performing rTSA for off-label indications may create liability risk for surgeons and implant manufacturers. Device manufacturers should formally expand indications of use for rTSA with the FDA to be consistent with published literature and trends. [ABSTRACT FROM AUTHOR]

Purpose: There is a common belief among some shoulder surgeons that the increased utilization of reverse shoulder arthroplasty (RSA) is driven by the operation being performed in younger patients. The primary purpose of this study was to evaluate the change in patient age at the time of primary RSA in the USA. Methods: All patients undergoing primary RSA (January 2011–June 2018) were identified in the Mariner database. The mean age at the time of primary RSA was evaluated for each patient and assessed in 6-month intervals. A longitudinal comparison over time was performed for all patients. Results: A total of 56,141 primary RSA were evaluated, with the mean age increasing from 69 in the 2011 to 71 in 2018 (p < 0.001). The largest increase in RSA utilization occurred in patients > 70 (1092 in 2011 to 3499 in 2018), with patients < 50 years demonstrating the slowest growth (13 in 2011 to 65 in 2018). However, when evaluated by percentage increase from 2011 to 2018, RSA volumes for patients < 60 have increased 390% compared to 220% for those > 70 years (p < 0.001). Conclusion: RSA continues to be performed at a similar mean age despite expanded indications and surgeon comfort. However, patients < 60 years have had a greater increase in utilization compared to patients > 70 years. The volumetric growth of RSA has largely been driven by the older population, but younger patients have shown a higher percentage of growth, which may explain the generalized observation that RSA is performed in younger patients. Level of Evidence: Level III; Retrospective comparative study; Treatment study. [ABSTRACT FROM AUTHOR]

Return-to-activity (RTA) assessments are commonly administered after anterior cruciate ligament reconstruction (ACLR) to manage the patient's postoperative progressions back to activity. To date, few data are available on the clinical utility of these assessments to predict patient outcomes such as secondary anterior cruciate ligament (ACL) injury once the athlete has returned to activity. To identify the measures of patient function at 6 months post-ACLR that best predict RTA and second ACL injury at a minimum of 2 years after ACLR. Prospective cohort study. Laboratory. A total of 234 patients with primary, unilateral ACLR completed functional assessments at approximately 6 months post-ACLR. Of these, 192 (82.1%) completed follow-up at ≥2 years post-ACLR. The 6-month functional assessments consisted of patient-reported outcomes, isokinetic knee-flexor and -extensor strength, and single-legged hopping. We collected RTA and secondary ACL injury data at ≥2 years after ACLR. Of the patients who were able to RTA (n = 155), 44 (28.4%) had a subsequent ACL injury, 24 (15.5%) to the ipsilateral graft ACL and 20 (12.9%) to the contralateral ACL. A greater proportion of females had a secondary injury to the contralateral ACL (15/24, 62.5%), whereas a greater proportion of males reinjured the ipsilateral ACL graft (15/20, 75.0%; P =.017). Greater knee-extension symmetry at 6 months increased the probability of reinjury (B = 0.016, P =.048). Among patients with RTA at < 8 months, every 1% increase in quadriceps strength symmetry at 6 months increased the risk of reinjury by 2.1% (B = 0.021, P =.05). Among patients with RTA at >8 months, every month that RTA was delayed reduced the risk of reinjury by 28.4% (B = –0.284, P =.042). Descriptive statistics of patient function stratified between the early and delayed RTA groups can be found in the Supplemental Table (available online at http://dx.doi.org/10.4085/1062-6050-0407.20.S1). Patients with more symmetric quadriceps strength at 6 months post-ACLR were more likely to experience another ACL rupture, especially those who returned to sport at < 8 months after the index surgery. Clinicians should be cognizant that returning high-functioning patients to activity at < 8 months post-ACLR may place them at an increased risk for reinjury. [ABSTRACT FROM AUTHOR]

Background: Meniscal injuries are commonly associated with anterior cruciate ligament (ACL) tears. Treatment of meniscal injuries can impart delayed weightbearing and range of motion restrictions, which can affect the rehabilitation protocol. The effect of meniscal treatment and subsequent restrictions on strength recovery after ACL reconstruction is unclear. Purpose/Hypothesis: The purpose of this study was to compare strength, jumping performance, and patient-reported outcomes between patients who underwent isolated ACL reconstruction (ACLR) and those who underwent surgical intervention for meniscal pathology at the time of ACLR. Our hypothesis was that patients who underwent concurrent meniscal repair (MR) would have lower strength recovery owing to postoperative restrictions. Study Design: Cohort study; Level of evidence, 3. Methods: Patients with ACLR were stratified into isolated ACLR, ACLR and meniscectomy (ACLR-MS), or ACLR-MR groups and were compared with healthy controls. The ACLR-MR group was restricted to partial weightbearing and to 90° of knee flexion for the first 6 weeks postoperatively. All participants completed patient-reported outcomes (International Knee Documentation Committee [IKDC] and Knee injury and Osteoarthritis Outcome Score [KOOS]) and underwent bilateral isokinetic and isometric strength tests of the knee extensor and flexor groups as part of a return-to-sports test battery at 5 to 7 months postoperatively. Results: A total of 165 patients with ACLR (50 with isolated ACLR, 44 with ACLR-MS, and 71 with ACLR-MR) and 140 healthy controls were included in the study. Follow-up occurred at a mean of 5.96 ± 0.47 months postoperatively. The control group demonstrated higher subjective knee function, unilateral peak extensor torque, and limb symmetry than did the ACLR-MS and ACLR-MR groups combined (P <.001 for all). There were no differences in IKDC, KOOS subscales, or unilateral or limb symmetry measures of peak knee extensor or flexor torque among the isolated ACLR, ACLR-MS, and ACLR-MR groups. Conclusion: Persistent weakness, asymmetry, and reduced subjective outcome scores at 6-month follow-up after ACLR were not influenced by meniscal treatment. These findings suggested that the weightbearing and range of motion restrictions associated with meniscal repair recovery do not result in loss of early strength or worse patient-reported outcomes.

Context: Understanding how muscles activate in a population with a previous glenohumeral-joint (GH) injury may help clinicians understand how to build a conservative treatment plan to strengthen or activate the specific muscles in an attempt to reduce recurrent shoulder injury and development of GH laxity. Objective: To investigate muscle-activation differences between the previously injured limb of individuals with a history of GH-joint injury and healthy matched controls during functional isometric contractions. Design: Case control. Setting: University research laboratory. Participants: 17 individuals (8 women, 9 men: age 22.3 ± 2.6 y, height 172.4 ± 8.8 cm, mass 75.4 ± 16.5 kg) with previous unilateral shoulder pain and 17 (8 women, 9 men; age 22.9 ± 3.9 y, height 170.9 ± 11.3 cm. mass 73.6 ± 22.9 kg) with no history of shoulder pain or injury. Intervention(s): Diagnostic ultrasound measurements of the supraspinatus were completed in both resting and contracted states to assess changes in muscle thickness. Manual muscle tests (anterior deltoid, upper trapezius, infraspinatus, lower trapezius, serratus anterior) and functional isometric contractions (forward flexion, scaption, abduction) were measured using electromyography. Main Outcome Measures: Peak, normalized activation of each muscle and supraspinatus thickness activation ratio were compared between groups and bilaterally within groups using separate ANOVAs. Results: The anterior deltoid was significantly less activated during all functional isometric tasks in previously injured subjects than in healthy subjects (P = .024). In previously injured subjects, the involved limb-lower trapezius was significantly less activated during scaption and abduction tasks than the contralateral side (P = .022 and P = .031, respectively). Conclusions: There were decreases in muscle activation in the anterior deltoid between previously injured and healthy people, as well as in the lower trapezius, in previously injured subjects. Understanding the source of muscleactivation deficits can help clinicians focus rehabilitation exercises on specific muscles. [ABSTRACT FROM AUTHOR]

Compare postoperative opioid usage following hemiarthroplasty (HA) and reverse total shoulder arthroplasty (RTSA) for proximal humerus fracture (PHFx). Humana insurance data was reviewed for patients undergoing RTSA or HA for PHFx from 2007 through the first quarter of 2017. The incidence of postoperative opioid usage within 1 year following surgery was collected in 1-month intervals and compared between HA and RTSA patients. Baseline opioid use was also characterized. Logistic regression analysis was utilized to assess risk factors for prolonged postoperative narcotic usage. Nine hundred fourty-seven HA and 2147 RTSA were performed for PHFx. There was no difference in preoperative opioid use between both groups (RTSA: 12.4%, HA: 11.5%; P =.5). At each monthly postoperative interval, a higher proportion of patients undergoing HA utilized opioids in comparison to RTSA (P <.003 for all comparisons). The rate of postoperative opioid usage declined in both groups with 8.7% and 13.3% of RTSA and HA patients continuing to fill opioid prescriptions at 1-year postoperatively (P <.001). There was a lower proportion of patients using opioids following RTSA compared to baseline (8.7% vs. 12.4%; P <.001); however, there was no difference in narcotic usage at final follow-up in patients treated with HA (13.3% vs. 11.5%; P =.2). HA was a risk factor for prolonged opioid usage following treatment of PHFx (odds ratio = 1.65 [1.39-1.96]; P <.001). Patients undergoing HA for PHFx have a higher incidence of opioid usage up to 1-year postoperatively compared to patients undergoing RTSA for the same diagnosis. Level III [ABSTRACT FROM AUTHOR]

Background: Patients often have quadriceps or hamstring weakness after anterior cruciate ligament reconstruction (ACLR), despite postoperative physical therapy regimens; however, little evidence exists connecting nerve blocks and ACLR outcomes. Purpose: To compare muscle strength at return to play in patients who received a nerve block with ACLR and determine whether a specific block type affected subjective knee function. Study Design: Cohort study; Level of evidence, 3. Methods: Patients were recruited 5 to 7 months after primary, isolated ACLR and completed bilateral isokinetic strength tests of the knee extensor/flexor groups as a single-session return-to-sport test. Subjective outcomes were assessed with the International Knee Documentation Committee (IKDC) score. Strength was expressed as torque normalized to mass (N·m/kg) and limb symmetry index as involved/uninvolved torque. Chart review was used to determine the type of nerve block and graft used. Nerve block types were classified as knee extensor motor (femoral nerve), knee flexor motor (sciatic nerve), or isolated sensory (adductor canal block/saphenous nerve). A 1-way analysis of covariance controlling for graft type was used. Results: A total of 169 patients were included. Graft type distribution consisted of 102 (60.4%) ipsilateral bone–patellar tendon–bone (BTB) and 67 (39.6%) ipsilateral hamstring tendon. Nerve block type distribution consisted of 38 (22.5%) femoral, 25 (14.8%) saphenous, 45 (26.6%) femoral and sciatic, and 61 (36.1%) saphenous and sciatic. No significant difference was found in knee extensor strength (P =.113) or symmetry (P =.860) between patients with knee extensor motor blocks (1.57 ± 0.45 N·m/kg; 70.1% ± 15.3%) and those without (1.47 ± 0.47 N·m/kg; 69.6% ± 18.8%). A significant difference was found between patients with knee flexor motor blocks (0.83 ± 0.26 N·m/kg) and those without (0.92 ± 0.27 N·m/kg) for normalized knee flexor strength (P =.21) but not knee flexor symmetry (P =.592). Controlling for graft type, there were no differences in subjective knee function (IKDC score) between all nerve block groups (P =.57). Conclusion: Our data showed that use of a sciatic nerve block with ACLR in patients with hamstring and BTB grafts influences persistent knee flexor strength deficits at time of return to sports. Although the cause of postoperative muscular weakness is multifactorial, this study adds to the growing body of evidence suggesting that perioperative nerve blocks affect muscle strength and functional rehabilitation after ACLR.

Background: Pass rates for return-to-play evaluations are alarmingly low for patients after anterior cruciate ligament reconstruction (ACLR). Since timing of return to play is a complicated decision, it is important that patients be given optimal time to realize meaningful improvements in strength that warrant additional testing. Purpose: To (1) compare outcomes among patients assessed at different time points after ACLR, (2) determine strength gains indicative of improvements in subjective function, and (3) determine the amount of time necessary to achieve meaningful strength gains. Study Design: Cross-sectional/case-control study; Level of evidence, 3. Methods: A total of 293 patients participated in the study after ACLR (mean ± SD, 23.2 ± 10.1 years old; n = 142 female participants; 6.4 ± 0.9 months after ACLR). Participants were stratified on the month of their evaluation after ACLR: 5 to 6 months (n = 122), 6 to 7 months (n = 102), 7 to 8 months (n = 43), and 8 to 9 months (n = 26). The International Knee Documentation Committee (IKDC) subjective form and knee extensor and flexor torque and symmetry, as assessed through an isokinetic dynamometer, were compared among groups. Forty patients (20 female participants, 20.4 ± 7.1 years old) were referred for subsequent testing (2.14 ± 0.78 months after initial visit). Subjective improvement between visits was defined as a ≥9-point change of the IKDC score. Thresholds of knee extensor torque and symmetry indicative of subjective improvement and the time between assessments needed to achieve these strength improvements were determined. Results: Patients between 5 and 6 months (IKDC, 79.7; interquartile range [IQR], 70.1-88.5) had lower subjective function compared to patients between 6 and 7 months (IKDC, 83.9; IQR, 74.5-92.0; P =.019) and 8 and 9 months after ACLR (IKDC, 89.1; IQR 75.8-92.3; P =.026). Patients between 5 and 6 months (1.41 N·m/kg; IQR, 1.16-1.73 N·m/kg]) had lower knee extensor torque compared to patients 6 and 7 months (1.59 N·m/kg; IQR, 1.23-1.95 N·m/kg; P =.013) and 7 and 8 months after ACLR (1.62 N·m/kg; IQR, 1.30-1.86 N·m/kg; P =.046). Patients between 5 and 6 months (66.4%; IQR, 54.2-78.6) had lower symmetry compared to patients between 6 and 7 months (71.8%; IQR,61.1-82.9; P =.019) and 8 and 9 months afterACLR (75.2%; IQR, 66.6-87.7; P =.014). Of the 40 patients that completed follow-up assessments, an increase in knee extensor torque of 0.22 N·m/kg and symmetry of 5.75% discriminated patients that achieved subjective improvement. A period of 1.97 months between assessments discriminated those that achieved the established symmetry threshold. Conclusion: Patients demonstrate increasing subjective and quadriceps function when tested at later time points from surgery; however, the observed values are low, suggesting that at 9 months patients are demonstrating deficits that may be improving. Approximately 2 months is needed to observe clinically meaningful improvements. [ABSTRACT FROM AUTHOR]

Background: Shoulder arthroscopy is well established as a highly effective and safe procedure for the treatment for several shoulder disorders and is associated with an exceedingly low risk of infectious complications. Few data exist regarding risk factors for infection after shoulder arthroscopy, as previous studies were not adequately powered to evaluate for infection. Purpose: To determine patient-related risk factors for infection after shoulder arthroscopy by using a large insurance database. Study Design: Case-control study; Level of evidence, 3. Methods: The PearlDiver patient records database was used to query the 100% Medicare Standard Analytic Files from 2005 to 2014 for patients undergoing shoulder arthroscopy. Patients undergoing shoulder arthroscopy for a diagnosis of infection or with a history of prior infection were excluded. Postoperative infection within 90 days postoperatively was then assessed with International Classification of Diseases, Ninth Revision codes for a diagnosis of postoperative infection or septic shoulder arthritis or a procedure for these indications. A multivariate binomial logistic regression analysis was then utilized to evaluate the use of an intraoperative steroid injection, as well as numerous patient-related risk factors for postoperative infection. Adjusted odds ratios (ORs) and 95% CIs were calculated for each risk factor, with P < .05 considered statistically significant. Results: A total of 530,754 patients met all inclusion and exclusion criteria. There were 1409 infections within 90 days postoperatively (0.26%). Revision shoulder arthroscopy was the most significant risk factor for infection (OR, 3.25; 95% CI, 2.7-4.0; P < .0001). Intraoperative steroid injection was also an independent risk factor for postoperative infection (OR, 1.46; 95% CI, 1.2-1.9; P = .002). There were also numerous independent patient-related risk factors for infection, the most significant of which were chronic anemia (OR, 1.58; 95% CI, 1.4-1.8; P < .0001), malnutrition (OR, 1.42; 95% CI, 1.2-1.7; P = .001), male sex (OR, 2.71; 95% CI, 2.4-3.1; P < .0001), morbid obesity (OR, 1.41; 95% CI, 1.2-1.6; P < .0001), and depression (OR, 1.36; 95% CI, 1.2-1.5; P < .0001). Conclusion: Intraoperative steroid injection was a significant independent risk factor for postoperative infection after shoulder arthroscopy. There were also numerous significant patient-related risk factors for postoperative infection, including revision surgery, obesity, male sex, chronic anemia, malnutrition, depression, and alcohol use, among others.

Background: Tenodesis of the long head of the biceps tendon has become a popular surgical treatment option for patients with pain or instability attributed to a diseased or unstable biceps tendon. No previous studies have characterized the practice patterns of surgeons performing biceps tenodesis in the United States. Purpose: To investigate current trends in both arthroscopic and open biceps tenodesis across time, sex, age, and region of the United States as well as associated charges. Study Design: Descriptive epidemiology study. Methods: Patients who underwent biceps tenodesis (Current Procedural Terminology [CPT] codes 23430 and 29828) for the years 2008 through 2011 were identified using the PearlDiver Patient Record Database, including both private-payer and Medicare data. These cohorts were then assessed for associated diagnoses using International Classification of Diseases, 9th Revision, codes and concomitant procedures using CPT codes. These searches yielded procedural volumes, sex and age distribution, regional volumes, and average per-patient charges. A χ2 linear-by-linear association analysis, Student t test, and linear regression were used for comparisons, with P\.05 considered significant. Results: A total of 44,932 biceps tenodesis procedures were identified from 2008-2011. The incidence of biceps tenodesis procedures per 100,000 database patients increased 1.7-fold over the study period, from 8178 in 2008 to 14,014 in 2011 (P < .0001). An increase in the overall percentage volume was noted in patients aged 60-69 years (P = .039) and 20-29 years (P = .016). The overall charges for arthroscopic tenodesis increased at a rate significantly greater than that of open tenodesis (P<.0001). Rotator cuff tear or sprain, bicipital tenosynovitis, biceps tendon rupture, superior labral lesion, and osteoarthritis were the most common diagnoses associated with biceps tenodesis procedures. A significant increase in isolated biceps tenodesis was also observed over the study period, from 1967 patients in 2008 to 3565 patients in 2011, representing a 1.8-fold increase. Conclusion: The incidence of biceps tenodesis has increased yearly from 2008-2011. Arthroscopic tenodesis has emerged as a more popular technique. Charges associated with the procedure have increased significantly. Significant regional variations in procedural incidences exist. [ABSTRACT FROM AUTHOR]

The article discusses a study focusing on the placement of femoral tunnel in posterior cruciate ligament (PCL) reconstruction, which compares the ability of outside-in (OI) and inside-out (IO) femoral tunnel drilling. It briefly describes comparison of PCL femoral footprint in OI and IO drilling by using preoperative and postoperative computed tomography (CT) scans. Findings of study revealed no difference between OI and IO techniques for use in femoral tunnel placement.

Background: During anatomic anterior cruciate ligament (ACL) reconstruction, we have found that the femoral footprint can best be visualized from the anteromedial portal. Independent femoral tunnel drilling can then be performed through an accessory medial portal, medial and inferior to the standard anteromedial portal.Purpose: To compare the accuracy of independent femoral tunnel placement relative to the ACL footprint using an accessory medial portal versus tunnel placement with a traditional transtibial technique.Study Design: Controlled laboratory study.Methods: Ten matched pairs of cadaveric knees were randomized such that within each pair, one knee underwent arthroscopic transtibial (TT) drilling, and the other underwent drilling through an accessory medial portal (AM). All knees underwent computed tomography (CT) both preoperatively and postoperatively with a technique optimized for ligament evaluation (80 keV with maximum mAs). Computed tomography was performed with a dual-energy scanner. Commercially available third-party software was used to fuse the preoperative and postoperative CT scans, allowing anatomic comparison of the ACL footprint to the drilled tunnel. The ACL footprint was marked in consensus by an orthopaedic surgeon and a musculoskeletal radiologist and then compared with the tunnel aperture after drilling. The percentage of tunnel aperture contained within the native footprint as well as the distance from the center of the tunnel aperture to the center of the footprint was measured.Results: The AM technique placed 97.7% ± 5% of the tunnel within the native femoral footprint, significantly more than 61.2% ± 24% for the TT technique (P = .001). The AM technique placed the center of the femoral tunnel 3.6 ± 1.2 mm from the center of the native footprint, significantly closer than 6.0 ± 1.9 mm for the TT technique (P = .003).Conclusion: This study demonstrates that use of an accessory medial portal will facilitate more accurate placement of the femoral tunnel in the native ACL femoral footprint.Clinical Relevance: More accurate placement of the femoral tunnel in the native ACL femoral footprint should improve the ability to achieve more anatomic positioning of the ACL graft.

Background: To our knowledge, there has been no prospective study on the results of arthroscopic repair of superior labrum-biceps anchor complex (SLAP) tears with use of modern techniques. The purpose of the present study was to prospectively evaluate the minimum two-year results for patients with type-II SLAP tears that were treated with arthroscopic suture anchor fixation. Methods: Forty-seven patients with symptomatic type-II SLAP tears were evaluated preoperatively and at least two years postoperatively with use of the American Shoulder and Elbow Surgeons (ASES) and L'lnsalata outcomes in- struments and physical examination. The study group included thirty-nine male and eight female patients with a mean age of thirty-six years; thirty-four of the forty-seven patients were athletes. Patients with rotator cuff tears requiring repair or concomitant shoulder instability were excluded. Results: At an average of 2.7 years, the median ASES and L'lnsalata scores were 97 and 93, respectively, compared with baseline scores of 62 and 65 (p < 0.05). The median patient-reported satisfaction rating was 9 (of 10); forty-one patients (87%) rated the outcome as good or excellent. The median patient-reported satisfaction rating was significantly higher for patients with a discrete traumatic etiology than for those with an atraumatic etiology (9 compared with 7); however, there was no significant difference between these groups in terms of the ASES or L'Insalata outcome scores. Overall, twenty-five (74%) of the thirty-four athletes were able to return to their preinjury level of competition, whereas eleven (92%) of the twelve athletes who reported a discrete traumatic event were able to return to their previous level of competition. There were five complications, including four cases of refractory postoperative stiffness. Conclusions: Our findings indicate that favorable outcomes can be anticipated in the majority of patients after arthroscopic SLAP lesion repair. While only three of four patients overall may be capable of returning fully to their previous level of competition, patients with a distinct traumatic etiology have a greater likelihood of a successful return to sports.
