Revision anterior cruciate ligament reconstruction is an increasingly common procedure, with 2-stage surgery often required to address large bone defects and malpositioned tunnels. The arthroscopic bone grafting technique described herein uses morselized allograft bone to provide reproducible fill of asymmetrical bone defects without autograft harvest or additional loss of native bone. The second stage of the anterior cruciate ligament reconstruction can typically proceed 6 months following bone grafting.

To evaluate the risk of post-operative infection after intra-articular steroid injection at the time of knee arthroscopy at a single institution high-volume sports medicine practice. The electronic medical record at a single institution was queried for all patients who underwent knee arthroscopy from 2011 to 2019. Patients were included if they underwent more simple arthroscopic procedures: diagnostic arthroscopy, meniscectomy, loose body removal, synovectomy, or microfracture. Patients were excluded if they underwent more complex procedures, such as ligament reconstruction, meniscus repair, or any open procedures. These patients’ medical records were then queried for current procedural terminology and international classification of disease codes indicating post-operative infection. Individual chart review was performed on this group of patients to determine if a true postoperative infection occurred within 6 months of the index arthroscopy. Patients were then categorized into “intra-operative steroid injection” versus “no steroid” based on each surgeon’s preferred intra-operative analgesic injection cocktail. A total of 6889 patients were identified, including 2416 (35.1%) who were given intra-articular steroid at the time of knee arthroscopy. Post-operative infection occurred in 10 patients (0.15%) at a median of 18 days (range 9–42 days), 7 who received intra-operative steroid injection (0.29%) and 3 who did not (0.067%), p = 0.040. The relative risk of infection for those who received intra-operative steroid injection was 4.32 times higher than those who did not, with a number needed to harm of 448. There were no significant differences in age, body mass index, smoking status, or the prevalence of diabetes between those who got infected and those who did not. Knee infection following arthroscopic surgery is rare. Intra-operative steroid injection during arthroscopic knee surgery is associated with a 4.3-fold increased risk of subsequent knee infection. While the overall risk remains low, the use of intra-operative steroids is expected to result in one additional knee infection for every 448 arthroscopic procedures performed. IV.

The intercondylar notch of the knee is a relatively small area. However, numerous rare pathologies can arise in this region. A majority of the existing literature has focused on the cruciate ligament injuries, yet there are several other entities that can cause knee pain from within the intercondylar notch. This review focuses on identifying the various diagnostic and treatment options for rare benign and malignant lesions including ganglion cyst formation, mucoid degeneration, benign proliferative conditions, and intra-articular tumors. These entities are most often diagnosed with advanced imaging studies and treated arthroscopically. While rare, these pathologies are important to identify in patients with ongoing vague knee pain.

Background: Elevated posterior tibial slope (PTS) has been identified as an important risk factor in anterior cruciate ligament (ACL) injuries and ACL graft failures. The cutoff value to recommend treatment with slope-reducing osteotomy remains unclear and is based on expert opinion and small case series. Purpose: (1) To determine whether there is a difference in PTS shown on lateral knee radiographs and magnetic resonance imaging (MRI) scans in a group of patients who experienced revision ACL graft failure versus a control group of patients who underwent successful revision ACL reconstruction, (2) to identify cutoff values of PTS measurements that predict risk of revision ACL graft failure, and (3) to examine whether there is a correlation between radiographic and MRI measurements of PTS. Study Design: Case-control study; Level of evidence, 3. Methods: A total of 38 patients who experienced revision ACL graft failure were identified from a revision ACL database. These patients were matched 1:1 by age, sex, and graft type to a group of 38 control patients who underwent revision ACL reconstruction with no evidence of graft failure at a minimum 2 years of follow-up. Medial and lateral PTS were measured by lateral knee radiographs and MRI scans of the affected limb. Demographics, surgical characteristics, and PTS were compared between the groups. The optimal cutoff values of medial and lateral PTS per radiographs and MRI scans for predicting increased risk of revision ACL graft failure were determined by receiver operating characteristic curves. Conditional multivariable logistic regression was used to assess the relative contribution of PTS cutoff values as a predictor of revision graft failure. Results: The mean PTS values in the failure group were significantly higher than those in the control group on radiographs (medial, 13.2°± 2.9° vs 10.3°± 2.9°; P < .001; lateral, 12.9°± 3.0° vs 9.8°± 2.8°; P < .001) and MRI scans (medial, 7.2°± 3.1° vs 4.8°± 2.9°; P < .001; lateral, 8.4 ± 3.1° vs 5.9 ± 3.0°; P < .001). A radiographic medial PTS ≥14° had the highest increased risk of revision ACL graft failure with sensitivity equal to 50% and specificity to 92.1% (odds ratio, 18.71; 95% CI, 2.0-174.9; P = .01). Conclusion: Elevated PTS was a significant risk factor for revision ACL graft failure. Patients with radiographic medial PTS ≥14° had 18.7-times increased risk of revision ACL failure.

The purpose of this study was to investigate the impact of articular cartilage damage on outcomes following medial patellofemoral ligament (MPFL) reconstruction.Record review identified 160 patients who underwent isolated MPFL reconstruction at a single institution between 2008 and 2016. Patient demographics, patellofemoral articular cartilage status at surgery, and patient anatomical measures from imaging were obtained via chart review. Patients were contacted and outcomes assessed through collection of Norwich Patellar Instability (NPI) score, Knee injury and Osteoarthritis Outcome Score (KOOS), and Marx activity score as well as an assessment for recurrent patellar dislocation. Outcomes of patients with grade 0-II patellofemoral cartilage damage were compared to those of patients with grade III-IV cartilage damage.One hundred twenty-two patients (76%) with a minimum of one year follow-up were contacted at a mean of 4.8 years post-operatively. A total of 63 patients (52%) had grade III or IV patellofemoral chondral damage at the time of surgery. The majority of the defects was on the medial patella (46 patients-72%) and the mean patellar defect size was 2.8 cmPatients with grade III or IV articular cartilage damage of the patellofemoral joint at the time of MPFL reconstruction demonstrated poorer KOOS knee-related quality of life than patients without grade III or IV articular cartilage damage at a mean of 4.8 years following isolated MPFL reconstruction.Level II.

We sought to determine the impact of bacterial inoculation and length of exposure on the mechanical integrity of soft tissue tendon grafts. Cultures of Staphylococcus epidermidis were inoculated on human tibialis posterior cadaveric tendon to grow biofilms. A low inoculum in 10% growth medium was incubated for 30 min to replicate conditions of clinical infection. Growth conditions assessed included inoculum concentrations of 100, 1000, 10,000 colony-forming units (CFUs). Tests using the MTS Bionix system were performed to assess the influence of bacterial biofilms on tendon strength. Load-to-failure testing was performed on the tendons, and the ultimate tensile strength was obtained from the maximal force and the cross-sectional area. Displacements of tendon origin to maximal displacement were normalized to tendon length to obtain strain values. Tendon force-displacement and stress-strain relationships were calculated, and Young's modulus was determined. Elastic modulus and ultimate tensile strength decreased with increasing bioburden. Young's modulus was greater in uninoculated controls compared to tendons inoculated at 10,000 CFU (p = 0.0011) but unaffected by bacterial concentrations of 100 and 1000 CFU (p = 0.054, p = 0.078). Increasing bioburden was associated with decreased peak load to failure (p = 0.043) but was most significant compared to the control under the 10,000 and 1000 CFU growth conditions (p = 0.0005, p = 0.049). The presence of S. epidermidis increased elasticity and decreased ultimate tensile stress of human cadaveric tendons, with increasing effect noted with increasing bioburden.

Valgus malalignment can be corrected with a biplanar lateral opening wedge distal femoral osteotomy (bLOWDFO) in patients with symptomatic lateral compartment disease. Advantages of a lateral opening wedge technique over the medial closing wedge technique include avoidance of vascular structures and theoretically better control of the amount of correction. The advantages of a bLOWDFO over a uniplanar osteotomy are that it creates a larger surface area for healing, and provides inherent stability to control the osteotomy intraoperatively. The purpose of this article is to present a reproducible technique for bLOWDFO and review the indications, preoperative planning, rationale, and clinical outcomes.

Hamstring injuries commonly occur at the musculotendinous junction; however, they can occur as proximal avulsion injuries. A lack of recognition can lead to proximal hamstring injuries being frequently misdiagnosed, resulting in delayed treatment. Chronic proximal hamstring tears are often retracted and scarred to the surrounding soft tissues. Owing to the poor quality of tissue at the torn ends of the tendon, an augmented reconstruction using an allograft may be required. In cases with poor visualization of the ischial tuberosity and proximal hamstring footprint, an Achilles tendon allograft can be secured directly to the tuberosity with suture anchors. However, visualization of the footprint can be optimized using an arthroscope. This report describes a technique for endoscopic-assisted anatomic reconstruction using an Achilles allograft with both knotless and knotted suture anchors for chronic complete avulsions of the proximal hamstring.

We hypothesize that larger prior tunnel size is associated with an increased risk of failure of single-stage revision anterior cruciate ligament reconstruction (ACLR) as defined by the performance of a re-revision (third) ACLR on the index knee. Retrospective review identified 244 patients who underwent single-stage revision ACLR at a single center with available preoperative radiographs. Patient and surgical factors were extracted by chart review. The maximum diameter of the tibial tunnel was measured on lateral radiographs and the maximum diameter of the femoral tunnel was measured on anteroposterior radiographs. Record review and follow-up phone calls were used to identify failure of the revision surgery as defined by re-revision ACLR on the index knee. One hundred and seventy-one patients (70%) were reviewed with a mean of 3.9 years follow-up. Overall, 23 patients (13.4%) underwent re-revision surgery. Mean tibial tunnel size was 12.6 ± 2.8 mm (range: 5.7–26.9 mm) and mean femoral tunnel size was 11.7 ± 2.8 mm (range: 6.0–23.0 mm). Re-revision risk increased with tibial tunnel size. Tibial tunnels 11 mm and under had a re-revision risk of 4.2%, while tunnels > 11 mm had a risk of 17.1% (relative risk: 4.1, p = 0.025). No significant association between femoral tunnel size and re-revision risk was noted. Patients with prior tibial tunnels > 11mm in diameter at revision surgery had significantly increased risk of re-revision ACLR. Further studies are needed to explore the relationship between prior tunnel size and outcomes of revision ACLR.

In orthopedic sports medicine, amniotic-derived products have demonstrated promising preclinical and early clinical results for the treatment of tendon/ligament injuries, cartilage defects, and osteoarthritis. The amniotic membrane is a metabolically active tissue that has demonstrated anti-inflammatory, antimicrobial, antifibrotic, and epithelialization-promoting features that make it uniquely suited for several clinical applications. Although the existing clinical literature is limited, there are several ongoing clinical trials aiming to elucidate the specific applications and benefits of these products. This article reviews the current amniotic-derived treatment options and the existing literature on outcomes, complications, and safety profile of these products for use in sports medicine.

Valgus malalignment can be corrected with a medial closing-wedge proximal tibia osteotomy in patients with symptomatic lateral compartment disease. Advantages of this technique include the inherent stability of the closing wedge with direct bone contact and reliable healing that enables early weight bearing and shorter recovery time. In addition, a tibial-based osteotomy alters joint contact forces in both flexion and extension versus femoral-based osteotomies. The purpose of this article is to present a reproducible technique for medial closing-wedge proximal tibia osteotomy and review the indications, preoperative planning, rationale, and clinical outcomes.

Objectives: Anterior cruciate ligament reconstruction (ACLR) graft failure continues to be a problem with failure rates reported up to 11%. Following revision ACLR, 3.3 – 4.3% of these patients suffer re-tear of the revision ACL graft. The purpose of this study was to evaluate the influence of posterior tibial slope (PTS) on ACL graft re-tear after revision ACLR. It was hypothesized that increased posterior tibial slope (PTS) is associated with an increased risk of ACL graft re-tear following revision ACLR. Methods: Retrospective chart review identified patients who underwent revision ACLR between 2005 and 2016 at a single institution. Patients who suffered an ACL re-tear following revision surgery were matched by age, sex, and graft type to controls who had intact revision ACLR grafts at a minimum of 2 years follow-up. Medial posterior tibial slope (MPTS) and lateral posterior tibial slope (LPTS) were measured on lateral radiographs and sagittal magnetic resonance imaging (MRI). Tibial slope was then compared between groups using independent sample t-tests. Results: Twenty-nine patients with a graft failure after revision ACLR were included and compared to 29 matched controls with a mean follow-up of 5.8 years (range: 2 to 11.3 years). Each group included 16 males and 13 females. Average age was 26 +/- 8.3 years at time of revision ACLR. Both x-ray and MRI demonstrated increased LPTS in the failure group versus controls (12.7 ± 3.2 degrees vs. 10.6 ± 3.6 degrees, p = 0.02 and 8.1 ± 3.4 degrees vs. 5.0 ± 3.5 degrees, p = 0.001, respectively). There was no significant difference in MPTS between the failure and control groups on x-ray (11.9 ± 2.9 degrees vs. 11.1 ± 3.6 degrees, p = 0.3772) nor MRI (4.3 ± 3.5 degrees vs. 3.3 ± 3.0 degrees, p = 0.2486). Conclusions: Matching for age, sex, and graft type, increased LPTS measured on both x-ray and MRI is associated with increased risk of a subsequent ACL injury following revision ACLR. Identification of at-risk patients may guide pre-operative discussions regarding revision ACL graft failure risk.

Purpose To analyze the clinical outcomes and survivorship of meniscal horizontal cleavage tear (HCT) repairs with hopes of guiding future treatment decisions. Methods Standard systematic review methodology was used. A comprehensive search of PubMed was conducted on June 1, 2019. The inclusion criteria were articles that were published in English, involved human subjects, and reported on at least 1 outcome after repair of HCTs. The exclusion criteria included technique guides and reviews, studies without full text available, and studies with HCT outcomes not separated from other repair groups. Effect heterogeneity was determined using the I2 measure. Forest plots were created in addition to a random-effects model to show the results. Results The systematic review yielded 19 studies evaluating 289 knees in a total of 273 patients. At most recent follow-up, there was a high probability of return to sport (93.1% [67 of 72]). Overall, 74% of patients (67 of 90) were symptom free at last follow-up, and 80% expressed satisfaction with their overall result (80 of 100). The most frequently reported subjective outcome was the Lysholm score, which improved from a preoperative study range of 48 to 79 (I2 = 20.7%, P = .283) to a postoperative study range of 56 to 99 (I2 = 49%, P = .081). The next most commonly reported was the International Knee Documentation Committee subjective score, which improved from a preoperative study range of 16 to 49 (I2 = 47.7%, P = .125) to a postoperative study range of 72 to 95 (I2 = 0%, P = .660). An overall 11.7% reported risk of reoperation was found, with most cases involving revision meniscectomy. Rates of complications beyond fixation failure were overall very low, with infrequent reports of septic arthritis and transitory dysesthesia. Conclusions The short- to intermediate-term results of repair of HCTs are comparable to prior studies. Survivorship is comparable to repairs of other types of meniscal tears with high rates of return to sport and low complication rates. Level of Evidence Level IV, systematic review of Level I-IV studies.

Several studies have identified graft diameter as a risk factor for failure following anterior cruciate ligament reconstruction (ACLR). The purpose of this study was to evaluate the effect of graft diameter on patient reported outcome measures (PROMS) following ACLR. We performed a retrospective review of prospectively collected data using a global surgical registry. 153 of 287 patients (53.3%) had complete data for each timepoint. Effect of graft diameter, graft type, femoral tunnel drilling technique, patient age, sex, and body mass index were evaluated. At 1-year post-operatively, a 1-mm increase in graft diameter was found to correlate with a 5.7-point increase in the Knee Injury and Osteoarthritis Outcome Score (KOOS) activity of daily living score (p = 0.01), a 10.3-point increase in the sport score (p=0.003), and a 9.8-point increase in the quality of life score (p=0.013). At 2-years post-operatively, a 1-mm increase in graft size was found to be marginally correlated with KOOS symptoms and sport scores. Patients undergoing hamstring autograft ACLR, increasing graft diameter can result in improved PROMS, specifically improved KOOS subscale scores at 1 and 2-years post-operative.

Posterior glenohumeral capsular rupture is a rare cause of posterior glenohumeral instability. With advances in imaging and arthroscopic techniques, diagnosis and treatment of posterior glenohumeral instability are becoming more common in practice. We present a technique for arthroscopic repair of a posterior glenohumeral capsular rupture with concomitant anterior and posterior labrum detachment. Arthroscopic fixation was facilitated by use of a 70° arthroscope through an anterior viewing portal to allow accurate placement of the posterior portal in preparation for knot tying. This arthroscopic technique resulted in a successful outcome.

Background: Recurrent patellar instability is frequently treated surgically with reconstruction of the medial patellofemoral ligament (MPFL). Patients with significant patella alta, trochlear dysplasia, and/or an elevated tibial tubercle–trochlear groove (TT-TG) distance may benefit from a concurrent bony procedure such as tibial tubercle osteotomy or trochleoplasty. The indications to perform such procedures are traditionally based on imaging criteria but remain controversial. Patellar apprehension is common in patients with patellar instability but typically resolves in higher degrees of knee flexion. Hypothesis: The persistence of patellar apprehension at greater than 60° of knee flexion is associated with patella alta, an increased TT-TG distance, and trochlear dysplasia. Study Design: Cross-sectional study; Level of evidence, 3. Methods: A total of 76 patients with recurrent patellar instability were prospectively identified in a sports medicine clinic. Patellar apprehension was evaluated in each patient. Apprehension was defined as the patient reporting that the patella felt unstable to lateral patellar translation. Apprehension was first assessed at full knee extension and repeatedly assessed as the knee was flexed in 10° intervals, as measured using a goniometer. The degree of flexion at which patellar apprehension disappeared was recorded. Plain radiographs and magnetic resonance imaging (MRI) scans were obtained for all patients. Patellar height was assessed with the Caton-Deschamps (CD) index, and trochlear morphology was assessed through measurements of the sulcus angle and depth on MRI and classified using the Dejour classification system. Imaging measurements of patients in whom apprehension resolved by 60° of knee flexion were compared with measurements for those with apprehension that persisted deeper into flexion. Results: Apprehension resolved by 60° of flexion in 56 patients and persisted into deeper flexion in 20 patients. The patients with a delayed resolution of apprehension demonstrated a higher CD index; elevated TT-TG distance; increased sulcus angle; decreased sulcus depth; and higher incidence of Dejour type B, C, or D dysplasia (all P < .05). Of the 20 patients with a delayed resolution of apprehension, 18 had either Dejour type B, C, or D dysplasia or a CD index of at least 1.30. A delayed resolution of apprehension was present in 11 of the 16 patients with Dejour type B, C, or D dysplasia. Conclusion: Overall, 90% of patients with significant patella alta and the majority of patients with high-grade trochlear dysplasia demonstrated patellar apprehension that persisted beyond 60° of knee flexion. Additionally, 90% of patients with persistent apprehension had significant patella alta and/or trochlear dysplasia. Further work is needed to evaluate the utility of these findings to inform surgical decision-making in this population.

Background: Patient-reported outcome (PRO) measures are progressively utilized as evaluation tools in preoperative and postoperative assessments in orthopaedic practice. Identifying the potential utility of psychosocial factors to predict patient-reported pain and functional outcomes is of increasing interest to determine which patients will derive the greatest benefit from surgical treatment. Purpose/Hypothesis: The purpose of this study was to determine potential predictive associations between the preoperative 12-Item Short Form Health Survey Mental Component Summary (SF-12 MCS) score, patient characteristics or osteochondral allograft (OCA) morphology, and PROs in patients who underwent OCA transplantation. We hypothesized that poor preoperative mental health is associated with diminished PROs at final follow-up. Study Design: Case-control study; Level of evidence, 3. Methods: A total of 67 patients with a mean follow-up of 2.7 ± 1.0 years (range, 2-6 years) with complete preoperative and at least 24-month postoperative SF-12 MCS, Knee injury and Osteoarthritis Outcome Score (KOOS), Tegner, Lysholm, and International Knee Documentation Committee (IKDC) scores were included in this study. Pearson correlation coefficients and linear regression models were used to distinguish associations between age, sex, smoking status, body mass index, workers’ compensation, previous surgery, concomitant surgery, number of grafts, defect location, total graft size, SF-12 MCS score, and postoperative PRO scores as well as their improvement from baseline (delta). Results: The SF-12 MCS showed significant correlation with the KOOS Activities of Daily Living subscale ( P = .015), KOOS Sport/Recreation subscale ( P = .024), and IKDC ( P = .039). In the multivariable linear regression models, the SF-12 MCS had no predictive association with any PRO measure. Patient sex contributed significantly to the final regression models of the KOOS Sport/Recreation ( P = .042), Tegner score ( P = .024), and Lysholm score ( P = .031). The SF-12 MCS showed no bivariate correlation with changes in any PRO score (delta) ( P > .05). Conclusion: Preoperative mental health status did not predict perceived functional outcomes as assessed by PRO measures at final follow-up. Female sex was negatively correlated with KOOS Sport/Recreation, Tegner, and Lysholm scores.

Background: Pathology of the long head of the biceps tendon is a well-known cause of shoulder pain that is commonly managed with arthroscopic suprapectoral biceps tenodesis when conservative treatment fails. Purpose: To present an arthroscopic knotless suprapectoral biceps tenodesis technique known as “Loop ’n’ Tack” tenodesis and to report the clinical outcomes of patients with a minimum 2 years of follow-up. Study Design: Case series; Level of evidence, 4. Methods: A retrospective review of all patients who had undergone Loop ’n’ Tack tenodesis between January 2009 and May 2014 was completed. Charts were reviewed, and patients were contacted for demographic data, time from surgery, concomitant procedures, and workers’ compensation status, as well as visual analog scale for pain, American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation, and University of California, Los Angeles (UCLA) scores. Results: Complete follow-up evaluations were performed for 59 of 68 patients (87%). Mean follow-up was 43 months. A majority (88%) of patients had at least 1 additional procedure performed at the time of biceps tenodesis. The mean ASES shoulder score improved from 42.6 preoperatively to 91.0 postoperatively ( P < .001), and 54 of 59 patients (91.5%) had a good/excellent outcome, with a UCLA shoulder score >27 and ASES shoulder score >70. Three patients (5%) reported biceps cramping pain with overuse, and 2 (3.3%) reported intermittent anterior shoulder pain. No patients had developed a “Popeye” deformity at final clinical examination, and 97% reported that they were overall satisfied with the procedure. Conclusion: The Loop ’n’ Tack tenodesis technique results in a high rate of patient satisfaction, significant improvement in shoulder outcome scores, and a low incidence of postoperative pain, with no reoperations for biceps-related pathology.

Objectives: Pathology of the long of head of the biceps tendon (LHB) is a well-known cause of shoulder pain that is commonly managed with arthroscopic suprapectoral biceps tenodesis when conservative treatment fails. The purpose of this study is to present an arthroscopic, knotless, suprapectoral biceps tenodesis technique known as the Loop ‘N’ Tack and report the clinical outcomes in patients with a minimum of 2 years follow-up. Methods: The technique grasps the LHB proximally at the superior labrum and fixes it to the most distally visualized portion of the intra-articular bicipital groove. A retrospective review of all patients who had undergone the Loop ‘N’ Tack biceps tenodesis by the senior author between January 2009 and May 2014 was completed. Patients were excluded if any portion of the surgery was performed open, or if they had less than 2 years of follow-up. Charts were reviewed and patients were contacted for demographic data, time from surgery, concomitant procedures, worker’s compensation (WC) status, visual analog scale (VAS), American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation (SANE), and University of California, Los Angeles (UCLA) scores. Statistical analysis was performed using Mann-Whitney U test for comparing non-parametric data sets. Results: follow-up evaluations were performed in 59 of 68 patients (87%). Average follow-up was 43 months. 88% of patients had at least 1 additional procedure performed at the time of biceps tenodesis. The mean ASES scores improved from 42.5 preoperatively to 90.1 postoperatively (p < 0.001). Fifty-four of fifty-nine patients (91.5%) had a good/excellent outcome with UCLA score > 27 and ASES > 70. Three patients (5%) reported biceps cramping pain with overuse. Two patients (3.3%) reported intermittent anterior shoulder pain similar to preoperative symptoms. No patients had developed a “Popeye” deformity at final clinical examination. 97% of patients reported that they were satisfied overall with the procedure. Comparing patients who had a rotator cuff repair or labrum repair at the time of biceps tenodesis with patients who did not have either, there were no significant differences in preoperative VAS or ASES, or postoperative outcomes scores. There were 10 WC patients who had worse postoperative VAS (p = 0.02), ASES (p = 0.03), SANE (p = 0.03), and UCLA scores (p = 0.02) compared to non-WC patients. Conclusion: The Loop ‘N’ Tack biceps tenodesis technique provides a high rate of patient satisfaction and high outcomes scores with a low rate of postoperative pain and no reported incidence of ‘Popeye’ deformity. We believe these good clinical results are due to the secure fixation of the LHB while relieving tension and minimizing motion of the tendon within the bicipital groove. [Figure: see text]
