Subpectoral Biceps Tenodesis for Tenosynovitis of the Long Head of the Biceps in Active Patients Younger Than 45 Years Old

Arthroscopic suprapectoral biceps tenodesis provided earlier shoulder function restoration compared with open subpectoral biceps tenodesis during the recovery phase

BACKGROUND

This study compared the clinical outcomes of open subpectoral biceps tenodesis and arthroscopic suprapectoral biceps tenodesis for symptomatic biceps tenosynovitis. Although both techniques have pros and cons, no studies have compared clinical and functional outcomes during the recovery phase. Previous studies show that suprapectoral tenodesis has a higher probability of Popeye deformity and postoperative bicipital pain and stiffness, whereas subpectoral tenodesis has a higher risk of nerve complications and wound infections. This study aimed for clinical comparison between arthroscopic suprapectoral biceps tenodesis and open subpectoral biceps tenodesis.

METHODS

This study is a retrospective review of institutional records of patients with biceps tendinitis who underwent open or arthroscopic biceps tenodesis. Surgical indications included biceps tenosynovitis, biceps partial tear, and biceps pulley lesion. Patients with prior shoulder surgery, preoperative shoulder stiffness, or full-thickness tear of rotator cuff were excluded. Tenodesis was considered when the pain recurs within 3 months despite conservative treatment including at least 2 triamcinolone injections on the biceps tendon sheath. Visual analog scale (VAS) score for pain, presence of the night pain, American Shoulder and Elbow Surgeons (ASES) score, Constant score, and range of motion were assessed preoperatively at 3, 6, 12, and 24 months postoperatively and the last follow-up.

RESULTS

A total of 72 patients (33 with arthroscopic suprapectoral biceps tenodeses and 39 with open subpectoral biceps tenodeses) were included in analysis. At postoperative 6 months, lower VAS score (0.4 ± 0.8 vs. 1.7 ± 1.9, P < .001), and the presence of the night pain (2 [6%] vs. 14 [36%], P = .002), ASES score (89.6 ± 9.2 vs. 81.4 ± 14.6, P = .006), and Constant score (89.4 ± 5.6 vs. 82.0 ± 12.5, P = .003) compared with the subpectoral group. The mean number of postoperative steroid injections for pain control in the subpectoral group (0.51 ± 0.80) was significantly higher than that in the suprapectoral group (0.18 ± 0.40) (P = .031). However, postoperative clinical outcomes were restored similar between the 2 groups at 12 months and the last follow-up.

DISCUSSION

Arthroscopic suprapectoral biceps tenodesis performed statistically better than the subpectoral biceps tenodesis for the VAS, ASES, night pain, and Constant score at postoperative 6 months. However, only night pain and the Constant score showed differences that exceeded minimum clinically important difference during the recovery phase. At postoperative 12 and 24 months, biceps tenodesis provided satisfactory clinical outcomes and pain relief regardless of the fixation technique and suture anchor location.

Minimum 5-Year Clinical Outcomes of Arthroscopically Repaired Massive Rotator Cuff Tears: Effect of Age on Clinical Outcomes

BACKGROUND

Massive rotator cuff tears (MRCTs) can be challenging to treat, and the efficacy of repair of MRCTs in older patients has been debated.

PURPOSE

To report minimum 5-year outcomes after primary arthroscopic rotator cuff repair of MRCT and determine whether age affects outcomes.

STUDY DESIGN

Case series; Level of evidence 4.

METHODS

The study included consecutive patients with MRCTs who were treated with arthroscopic rotator cuff repair by a single surgeon between February 2006 and October 2016. MRCTs were defined as ≥2 affected tendons with tendon retraction to the glenoid rim and/or a minimum exposed greater tuberosity of ≥67. Patient-reported outcome (PRO) data collected preoperatively and at a minimum of 5 years included the American Shoulder and Elbow Surgeons (ASES) score; Single Assessment Numeric Evaluation (SANE) score; the shortened version of the Disabilities of the Arm, Shoulder and Hand score (QuickDASH); the 12-Item Short Form Health Survey (SF-12) Physical Component Summary (PCS); and patient satisfaction. Surgical failure was defined as subsequent revision rotator cuff surgery or conversion to reverse total shoulder arthroplasty. Regression analysis was performed to determine whether age had an effect on clinical outcomes.

RESULTS

A total of 53 shoulders in 51 patients (mean age, 59.7 years; range, 39.6-73.8 years; 34 male, 19 female) met inclusion criteria with a mean follow-up of 8.1 years (range, 5.0-12.1 years). Three shoulders (5.7%) failed at 2.4, 6.0, and 7.1 years. Minimum 5-year follow-up was obtained in 45 of the remaining 50 shoulders (90%). Mean PROs improved as follows: ASES from 58.8 to 96.9 (P < .001), SANE from 60.5 to 88.5 (P < .001), QuickDASH from 34.2 to 6.8 (P < .001), and SF-12 PCS from 41.1 to 52.2 (P < .001). Patient satisfaction was a median of 10 (on a scale of 1-10). Age was not associated with any PRO measures postoperatively (P > .05).

CONCLUSION

This study demonstrated significantly improved clinical scores, decreased pain, and increased return to activity for patients with MRCT at midterm follow-up (mean, 8.1 years; range, 5.0-12.1 years). In this patient cohort, no association was found between age and clinical outcomes.

Does the timing of tenotomy during biceps tenodesis affect the incidence of Popeye deformity and clinical outcome? An analysis of short-term follow-up of 2 techniques

BACKGROUND

There are multiple techniques that attempt to maintain anatomic length-tension relationship during biceps tenodesis. However, no direct comparison has been performed with respect to the timing of biceps tenotomy during biceps tenodesis. This study aims to assess the incidence of Popeye deformity and clinical outcomes of 2 all-arthroscopic techniques for biceps tenodesis based on timing of the biceps tenotomy.

METHODS

A consecutive series of patients undergoing arthroscopic biceps tenodesis with concomitant rotator cuff tears were enrolled from 2019 to 2021. Biceps tenodesis performed after tenotomy formed the first cohort (group 1). The other cohort had biceps tenodesis performed prior to biceps tenotomy (group 2). Postoperative anterior arm pain, biceps muscle spasms, and patient perceptions of the appearance of the bicep muscle were assessed. In addition, patient-reported outcomes (PROs) were collected at 3 months and minimum 6 months postoperatively.

RESULTS

A total of 71 patients were eligible for participation and 62 patients (53% female, age 58.7 ± 9.0 years) were enrolled (n = 33 in group 1, and n = 29 in group 2). There were no differences between groups with respect to gender, age, and laterality of biceps tenodesis, as well as type and size of rotator cuff repair. At 3-month follow-up, Veterans RAND 12-Item Health Survey (VR-12) physical health summary scores were significantly improved in group 2 (44.8 ± 9.7) compared with group 1 (34.1 ± 3.4) (P = .03). In addition, patients in group 2 experienced significantly less pain in their anterior arm than patients in group 1 (19% vs. 33%, P = .02). There were no differences in biceps muscle spasm (3.4% vs. 5.2%, P = .21) and no other differences in PROs between groups. Final follow-up averaged 11.6 ± 3.3 months in group 1 and 11.8 ± 5.5 months in group 2. There were no significant differences in patient-perceived biceps Popeye deformity between group 1 (12.1%) and group 2 (0%) (P = .652). Furthermore, there were no differences in American Shoulder and Elbow Surgeons Standardized Shoulder Assessment Form, EuroQol-5 Dimension, Patient-Reported Outcomes Measurement Information System Global Health (PROMIS 10) physical health, PROMIS 10 depression, VR-12 physical health summary, and Single Assessment Numeric Evaluation scores between the 2 technique groups.

CONCLUSION

Patients with tenotomy performed after tenodesis had better VR-12 physical health summary scores and less arm pain than patients with tenotomy performed before tenodesis at 3-month follow-up. However, there were no differences in any outcome at final follow-up of nearly 1-year. In addition, there were no differences in perceived Popeye deformity between groups at any time period.

Physical Therapy Interventions for the Management of Biceps Tendinopathy: An International Delphi Study

Background

Shoulder pain related to the long head of the biceps tendon (LHBT) tendinopathy can be debilitating and difficult to treat especially in athletes who often elect for surgical intervention. Conservative management is recommended but there are limited established guidelines on the physical therapy (PT) management of the condition.

Hypothesis/Purpose

The purpose of this study was to establish consensus on conservative, non-surgical physical therapy interventions for individuals with LHBT tendinopathy using the Delphi method approach.

Study Design

Delphi Study.

Methods

Through an iterative process, experts in the PT field rated their agreement with a list of proposed treatment interventions and suggested additional interventions during each round. Agreement was measured using a four-point Likert scale. Descriptive statistics including median and percentage agreement were used to measure agreement. Data analysis at the end of Round III produced, by consensus, a list of PT interventions recommended for the management of individuals with LHBT tendinopathy. Consensus was defined as an a priori cutoff of ≥75% agreement.

Results

The respondent group included 29 international experts in the PT management of individuals with shoulder pain. At the conclusion of the study 61 interventions were designated as recommended based on consensus amongst experts and 9 interventions were not recommended based on the same criteria, 15 interventions did not achieve consensus.

Conclusion

There is a lack of well-defined, PT interventions used to treat LHBT tendinopathy. Expert respondents reached consensus on multimodal interventions including exercise, manual therapy and patient education to manage LHBT tendinopathy.

Two-Year Clinical Outcomes and Survivorship After Isolated Biceps Tenodesis

PURPOSE

The purpose of this study was to evaluate clinical outcomes and survivorship of isolated biceps tenodesis (BT) at a minimum of 2 years and to identify patient-specific factors associated with these outcomes in patients undergoing BT without concomitant rotator cuff repair (RCR). We hypothesized that patient-reported outcomes would be significantly improved on American Shoulder and Elbow Surgeons Survey (ASES) and Single Assessment Numeric Evaluation (SANE), with a high rate of survivorship (>90%) at 2-year follow-up.

METHODS

A retrospective review of an institutional registry was performed to identify patients who underwent BT from July 2016 to December 2017. Patients >18 years old who underwent an open or arthroscopic BT procedure using an interference screw, button, or anchor for underlying bicipital pathology, without a concomitant RCR or shoulder arthroplasty, and were a minimum of 2 years postoperative were included. Patients were administered ASES and SANE questionnaires preoperatively and at final follow-up. Survivorship was evaluated using Kaplan-Meier analysis. Failure was defined as any patient who underwent reoperation related to the index surgery.

RESULTS

A total of 110 patients (mean ± standard deviation age, 48.60 ± 12.14 years) who underwent isolated BT with a follow-up of 24.90 ± 3.95 months were included in analysis. There was a significant improvement in ASES and SANE at final follow-up (P < .001), with 81% to 84% of patients achieving minimal clinically important difference (MCID), 72% to 82% achieving substantial clinical benefit (SCB), and 72% to 80% achieving patient-acceptable symptom state (PASS). Worker's Compensation (WC) patients had a decreased likelihood of achieving PASS on ASES (P = .015) and SANE (P = .012). Four cases were deemed failures (3 revision BTs and 1 capsular debridement) at 15.09 ± 9.57 months. WC did not have a significant effect on likelihood of BT failure.

CONCLUSION

Biceps tenodesis provided significant clinical improvement and high rates of survivorship 2 years postoperatively. WC was associated with a decreased likelihood of achieving PASS. These results support the continued use of isolated BT for treating biceps pathology.

SLAP Repair Versus Subpectoral Biceps Tenodesis for Isolated SLAP Type 2 Lesions in Overhead Athletes Younger Than 35 Years: Comparison of Minimum 2-Year Outcomes

Background:

It remains unclear if young overhead athletes with isolated superior labrum anterior-posterior (SLAP) type 2 lesions benefit more from SLAP repair or subpectoral biceps tenodesis.

Purpose:

To evaluate clinical outcomes and return to sport in overhead athletes with symptomatic SLAP type 2 lesions who underwent either biceps tenodesis or SLAP repair.

Study Design:

Cohort study; Level of evidence, 3.

Methods:

A retrospective analysis of prospectively collected data was performed in patients who underwent subpectoral biceps tenodesis (n = 14) or SLAP repair (n = 24) for the treatment of isolated type 2 SLAP lesions. All patients were aged <35 years at time of surgery, participated in overhead sports, and were at least 2 years out from surgery. Clinical outcomes were assessed with the American Shoulder and Elbow Surgeons (ASES) score; Single Assessment Numerical Evaluation (SANE) score; Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) score; and the 12-Item Short Form (SF-12) physical component score. Return to sport and patient satisfaction were documented. Clinical failures requiring revision surgery and complications were reported.

Results:

Preoperative baseline scores in both the tenodesis and SLAP repair groups were similar. There were no significant differences between the groups on any postoperative outcome measure: For biceps tenodesis versus SLAP repair, the ASES score was 92.7 ± 10.4 versus 89.1 ± 16.7, the SANE score was 86.2 ± 13.7 versus 83.0 ± 24.1, the QuickDASH score was 10.0 ± 12.7 versus 9.0 ± 14.3, and SF-12 was 51.2 ± 7.5 versus 52.8 ± 7.7. No group difference in return-to-sports rate (85% vs 79%; P = .640) was noted. More patients in the tenodesis group (80%) reported modifying their sporting/recreational activity postoperatively because of weakness compared with patients in the SLAP repair group (15%; P = .022). One patient in each group progressed to surgery for persistent postoperative stiffness, and 1 patient in the tenodesis group had a postoperative complication related to the index surgery.

Conclusion:

Both subpectoral biceps tenodesis and SLAP repair provided excellent clinical results for the treatment of isolated SLAP type 2 lesions, with a high rate of return to overhead sports and a low failure rate, in a young and high-demanding patient cohort. More patients reported modifying their sporting/recreational activity because of weakness after subpectoral tenodesis.

No Difference in Clinical Outcomes for Arthroscopic Suprapectoral Versus Open Subpectoral Biceps Tenodesis at Midterm Follow-up: A Randomized Prospective Analysis

BACKGROUND

We have previously reported the 1-year outcomes of arthroscopic suprapectoral biceps tenodesis (ASPBT) versus open subpectoral biceps tenodesis (OSPBT) for the management of long head of the biceps tendon (LHBT) pathology. While patients had similar 1-year biceps muscle strength and pain, longer-term functional outcomes are unknown.

PURPOSE

To directly compare clinical outcomes of ASPBT versus OSPBT with interference screw fixation, distal to the bony bicipital groove, at a minimum of 2 years' follow-up.

STUDY DESIGN

Randomized controlled trial; Level of evidence, 1.

METHODS

A total of 85 patients undergoing biceps tenodesis (BT) for LHBT disease were randomized into the ASPBT or OSPBT group. Both techniques utilized polyether ether ketone inference screws for tenodesis fixation. Patients completed American Shoulder and Elbow Surgeons (ASES), Constant subjective, and Single Assessment Numeric Evaluation (SANE) questionnaires preoperatively and again at 6 months, 12 months, and at the final follow-up at a minimum of 24 months.

RESULTS

A total of 73 patients (37/42 randomized to ASPBT [88%]; 36/42 randomized to OSPBT [86%]) with a mean age of 50.4 ± 10.3 years and a mean body mass index of 29 ± 7.9 were included in clinical outcome analyses. The mean final follow-up was 2.9 years (ASPBT, 3 years; OSPBT, 2.8 years [range 2-5.2 years]). Comparison of demographic characteristics and intraoperative findings showed no significant differences in age, sex, concomitant procedures, and rotator cuff disease. No statistically significant differences in the ASES (P = .25), Constant subjective (P = .52), and SANE scores (P = .61) were found at the final follow-up. Clinical outcomes scores showed no significant improvement from a mean of 12.6 months to the final follow-up at 34.5 months (ASPBT: ASES, P = .43; Constant, P = .25; SANE, P = .45 vs OSPBT: ASES, P = .65; Constant, P = .78; SANE, P = .70). No patients required revision of BT in either group.

CONCLUSION

This study reported a minimum of 2-year follow-up of patients undergoing ASPBT or OSPBT, utilizing the same interference screw technique, for the management of LHBT pathology in the setting of concomitant shoulder procedures. There were no significant differences in patient-reported outcomes and complication rates found at any time point.

How Long Does It Take to Achieve Clinically Significant Outcomes After Isolated Biceps Tenodesis?

Background:

Clinically significant outcomes (CSOs) connect patient-reported outcome measures data to patient-perceived benefit. Although investigators have established threshold values for various CSOs, the timeline to achieve these outcomes after isolated biceps tenodesis (BT) has yet to be defined.

Purpose:

To define the time-dependent nature of minimal clinically important difference (MCID), substantial clinical benefit (SCB), and Patient Acceptable Symptom State (PASS) achievement after isolated BT.

Study Design:

Case series; Level of evidence, 4.

Methods:

The American Shoulder and Elbow Surgeons score (ASES), the Single Assessment Numeric Evaluation, and the Constant-Murley score (CMS) were administered preoperatively and at 6 and 12 months postoperatively to patients undergoing isolated BT between 2014 and 2018 at our institution. Cumulative probabilities for achieving MCID, SCB, and PASS were calculated using Kaplan-Meier survival analysis. Weibull parametric regression evaluated the hazard ratios (HRs) of achieving earlier MCID, SCB, and PASS.

Results:

Overall cohort (N = 190) achievement rates ranged between 77.8% and 83.2% for MCID, between 42.2% and 80.2% for SCB, and between 59.7% and 62.9% for PASS. Median achievement time was 5.3 to 6.1 months for MCID, 5.9 to 6.4 months for SCB, and 6.07 to 6.1 months for PASS. Multivariate Weibull parametric regression identified older age, male sex, higher body mass index, preoperative thyroid disease, smoking history, and higher preoperative CMS as predictors of delayed CSO achievement (HR, 1.01-6.41), whereas normal tendon on arthroscopy, defined as absence of tenosynovitis or tendon tear on arthroscopy, predicted earlier CSO achievement (HR, 0.19-0.46). Location of tenodesis and worker compensation status did not significantly predict the time to achieve CSOs on multivariate analysis.

Conclusion:

After isolated BT, patients can expect to attain CSO by 13 months postoperatively, with most patients achieving this between 5 and 8 months. Patients tend to take longer to achieve PASS than MCID and SCB.

Management of proximal biceps tendon pathology

The long head of the biceps tendon is widely recognized as an important pain generator, especially in anterior shoulder pain and dysfunction with athletes and working individuals. The purpose of this review is to provide a current understanding of the long head of the biceps tendon anatomy and its surrounding structures, function, and relevant clinical information such as evaluation, treatment options, and complications in hopes of helping orthopaedic surgeons counsel their patients. An understanding of the long head of the biceps tendon anatomy and its surrounding structures is helpful to determine normal function as well as pathologic injuries that stem proximally. The biceps-labral complex has been identified and broken down into different regions that can further enhance a physician’s knowledge of common anterior shoulder pain etiologies. Although various physical examination maneuvers exist meant to localize the anterior shoulder pain, the lack of specificity requires orthopaedic surgeons to rely on patient history, advanced imaging, and diagnostic injections in order to determine the patient’s next steps. Nonsurgical treatment options such as anti-inflammatory medications, physical therapy, and ultrasound-guided corticosteroid injections should be utilized before entertaining surgical treatment options. If surgery is needed, the three options include biceps tenotomy, biceps tenodesis, or superior labrum anterior to posterior repair. Specifically for biceps tenodesis, recent studies have analyzed open vs arthroscopic techniques, the ideal location of tenodesis with intra-articular, suprapectoral, subpectoral, extra-articular top of groove, and extra-articular bottom of groove approaches, and the best method of fixation using interference screws, suture anchors, or cortical buttons. Orthopaedic surgeons should be aware of the complications of each procedure and respond accordingly for each patient. Once treated, patients often have good to excellent clinical outcomes and low rates of complications.

Isolated Biceps Tenodesis and Tenotomy: A Systematic Review of Indications and Patient Satisfaction

Biceps tenodesis and tenotomy are increasingly being used as treatment options for shoulder pathology, but patient satisfaction remains largely unstudied. A systematic review of the MEDLINE database was conducted to identify clinical outcome studies on isolated biceps tenodesis or tenotomy that reported patient satisfaction. Within the 15 investigations that were included, the indication for tenotomy was rotator cuff pathology, whereas the indication for tenodesis was biceps pathology or type 2 superior labral tear from anterior to posterior. Patients undergoing tenotomy were 13.6 years older than those undergoing tenodesis (P<.001). Patient satisfaction was high following both procedures, at 85.6% following tenotomy and 92.3% following tenodesis. [Orthopedics. 2021;44(6):333-340.].

Predicting Patient Satisfaction With Maximal Outcome Improvement After Biceps Tenodesis

The goal of this study was to determine the threshold for achieving maximal outcome improvement (MOI) on the American Shoulder and Elbow Surgeons (ASES), Single Assessment Numeric Evaluation (SANE), and Constant-Murley (CM) questionnaires that predict satisfaction after isolated biceps tenodesis without concomitant rotator cuff repair. A retrospective analysis of prospectively collected data was performed for patients undergoing isolated biceps tenodesis from 2014 to 2017 at a single institution with minimum 6-month follow-up. Receiver operating characteristic curve analysis was used to determine thresholds for MOI for the ASES, SANE, and CM questionnaires. Stepwise multivariate logistical regression analysis was performed to identify predictors for achieving the threshold for MOI. A total of 123 patients were included in the final analysis. Receiver operating characteristic analysis determined that achieving 43.1%, 62.1%, and 61.4% MOI was the threshold for satisfaction for the ASES, SANE, and CM questionnaires, respectively. Regression analysis showed that concomitant superior labrum anterior-posterior (SLAP) repair was predictive of achieving MOI on the ASES and SANE questionnaires, whereas partial rotator cuff tear was predictive of achieving MOI on the CM questionnaire (P<.05 for both). Further, workers' compensation status, diabetes, history of ipsilateral shoulder surgery, and hypertension were negative predictors of achieving MOI on the SANE and CM questionnaires (P<.05 for all). Achieving MOI of 43.1%, 62.1%, and 61.4% is the threshold for satisfaction after biceps tenodesis for the ASES, SANE, and CM questionnaires, respectively. Concomitant SLAP repair was positively predictive of achieving MOI, whereas workers' compensation status, diabetes, history of ipsilateral shoulder surgery, and hypertension were negative predictors. [Orthopedics. 2021;44(3):e359-e366.].

Could superior capsule findings be used as a predictor for partial bursal-sided rotator cuff tears?

PURPOSE

The purpose of this study was to investigate the relationship between the superior capsule tear patterns and synovitis with subacromial pathologies, such as bursal-sided rotator cuff tear and subacromial impingement syndrome.

METHODS

Fifty patients who underwent arthroscopic treatment for isolated bursal-sided tear were included in the study. Fifty more patients who underwent arthroscopic treatment for isolated Superior Labrum Anterior Posterior (SLAP) 2 lesion without pathology in the rotator cuff were included in the control group. Firstly, superior capsule tear and common synovitis on the rotator cable were assessed during glenohumeral joint examination. Coracoacromial Ligament (CAL) degeneration grading was performed according to the Royal Berkshire Hospital classification. Bursal-sided partial tear grading was done using Ellman classification. Whether or not there was a relationship between synovitis, classic capsule tear, plus reverse flap capsule tear, and partial bursal-sided tear existence.

RESULTS

There were 21 patients with reverse flap capsule tear in the study group and 3 patients in the control group. In addition, there were 13 patients with synovitis in the study group and 4 in the control group. Compared to the control group, there was also a significant positive correlation in the presence of both synovitis and reverse flap capsule tear with the presence of bursal-sided tear in the study group (p = 0.000). There was, however, no significant difference between the presence of classical capsule tear and the presence of bursal-sided tear (p = 0.485).

CONCLUSION

This study shows that the presence of reverse flap capsule tear and synovitis was associated with partial bursal-sided tears. Therefore, if the reverse flap capsule tear or synovitis is detected in the superior capsule, the rotator cuff should be evaluated in more detail during subacromial bursoscopy in order not to miss a bursal-sided partial cuff tear.

Conversion of Failed Proximal Long Head of the Biceps Tenodesis to Distal Subpectoral Tenodesis: Outcomes in an Active Population

PURPOSE

To assess failure rates and patient reported outcomes following revision of failed proximal long head of the biceps (LHB) tenodesis.

METHODS

Patients from an active-military population who underwent revision proximal (suprapectoral) to distal (subpectoral) LHB tenodesis were prospectively enrolled. Patients were included if they were between the ages of 16 and 60 years presenting after a previous biceps tenodesis with mechanical failure and clinical failure, defined as Single Assessment Numeric Evaluation (SANE) or American Shoulder and Elbow Surgeons (ASES) <70. Exclusion criteria were concomitant rotator cuff repair or debridement, full-thickness rotator cuff tear, extensive labral tears, or any evidence of glenohumeral arthritis. Pre- and postoperative SANE and ASES were documented and analyzed.

RESULTS

From 2004 to 2010, a total of 12 patients (all male) with a mean age of 39.9 years (range, 30-54 years) were assessed at a mean follow-up time of 29 months (range, 24-38 months). Nine patients presented with a failed tenodesis construct located at the top of the bicipital groove and 9 patients had LHB tendons originally affixed with an interference screw. Diagnostic arthroscopy revealed that the majority of patients (10/12) had excessive scarring at the site of previous fixation. Mean preoperative assessments of SANE (70.4) and ASES (59.9) improved postoperatively to SANE (90.3; P < .01) and ASES (89.8; P < .01). No patients were lost due to follow-up, and there were no reported complications or failures. All patients returned to full active duty and were able to perform all required physical tests before returning to their vocation.

CONCLUSIONS

Patients presenting with symptoms following a proximal LHB tenodesis can be successfully converted to a distal (subpectoral) LHB tenodesis with favorable outcomes. Although in a small sample, there was excessive scarring and synovitis in a majority, which improved significantly when treated with a revision subpectoral tenodesis with minimal complication risk and no reported failures.

Effectiveness and safety of tenosynovitis of the long head of the biceps brachii with acupuncture: a protocol for a systematic review and meta-analysis

Background

Tenosynovitis of the long head of the biceps (LHB) brachii is a common disease in patients over 40 years old. It can always result in chronic anterior shoulder pain and limited function. Acupuncture is one of most popular conservative treatment methods, and increasing studies indicate that it has remarkable therapeutic effects on the tenosynovitis of LHB brachii. However, the effectiveness and safety of acupuncture for treating tenosynovitis of LHB brachii remain largely uncertain. In our study, we will perform the first systematic review and meta-analysis to explore the effectiveness and safety of acupuncture on the tenosynovitis of LHB brachii.

Methods

We will search the randomized controlled trial (RCT) literatures involving acupuncture for treating tenosynovitis of LHB brachii in eight electric databases, including PubMed, Web of Science, EMBASE, the Cochrane Library, Chinese National Knowledge Infrastructure (CNKI), Chinese Biomedical Literature Database (CBM), Wanfang Database, and Technology Periodical Database (VIP). We will define the visual analog scale (VAS), the Melle score of shoulder joint functional activity, and the ability assessment of daily living activities (ADL) as the primary outcomes. Besides quality of life, adverse events caused by acupuncture will be regarded as the secondary outcomes. Quality assessment of the included studies will be independently performed according to the Cochrane Risk of Bias tool. Meanwhile, the level of evidence for results will be assessed by using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) method. All analyses will be conducted by using the RevMan software V5.3.

Results

From the study, we will ascertain the effectiveness and safety of acupuncture treatment on tenosynovitis of LHB brachii.

Conclusion

The conclusion of this study will confirm the effectiveness and safety of acupuncture in the treatment of tenosynovitis of LHB brachii, which can provide new evidence to guide appropriate interventions on tenosynovitis of LHB brachii with acupuncture in the future.

Ethics and dissemination

Ethical approval is not required because no individual patient data are collected. This review will be published in a peer-reviewed journal and presented at an international academic conference for dissemination.

Outcomes and Complications After Primary Arthroscopic Suprapectoral Versus Open Subpectoral Biceps Tenodesis for Superior Labral Anterior-Posterior Tears or Biceps Abnormalities: A Systematic Review and Meta-analysis

Background:

Biceps tenodesis is a surgical treatment for both superior labral anterior-posterior (SLAP) tears and long head of the biceps tendon (LHBT) abnormalities. Biceps tenodesis can be performed either above or below the pectoralis major tendon with arthroscopic or open techniques.

Purpose:

To analyze the outcomes and complications comparing primary arthroscopic suprapectoral versus open subpectoral biceps tenodesis for either SLAP tears or LHBT disorders.

Study Design:

Systematic review; Level of evidence, 4.

Methods:

A search strategy based on the PRISMA (Preferred Reporting Items for Systematic Meta-Analyses) protocol was used to include 18 articles (471 patients) from a total of 974 articles identified. Overall exclusion criteria included the following: non–English language, non–full text, biceps tenodesis with concomitant rotator cuff repair, review articles, meta-analyses, and case reports. Data were extracted and analyzed according to procedure type and tenodesis location: arthroscopic suprapectoral biceps tenodesis (295 patients) versus open subpectoral bicepts tenodesis (176 patients).

Results:

For arthroscopic suprapectoral biceps tenodesis, the weighted mean American Shoulder and Elbow Surgeons (ASES) score was 90.0 (97 patients) and the weighted mean Constant score was 88.7 (108 patients); for open subpectoral biceps tenodesis, the mean ASES score was 91.1 (199 patients) and mean Constant score was 84.7 (65 patients). Among the 176 patients who underwent arthroscopic biceps tenodesis, there was an overall complication rate of 9.1%. Among the 295 patients who underwent open biceps tenodesis, there was an overall complication rate of 13.5%. Both residual pain (5.7% vs 4.7%, respectively) and Popeye deformity (1.7% vs 1.0%, respectively) rates were similar between the groups. Open subpectoral biceps tenodesis had higher reoperation (3.0% vs 0.0%, respectively), wound complication (1.0% vs 0.0%, respectively), and nerve injury (0.7% vs 0.0%, respectively) rates postoperatively. A meta-analysis of 3 studies demonstrated that both methods had similar ASES scores (P = .36) as well as all-cause complication rates (odds ratio, 0.76 [95% CI, 0.13-4.48]; P = .26).

Conclusion:

Patients undergoing arthroscopic suprapectoral biceps tenodesis for either SLAP tears or LHBT abnormalities had similar outcome scores and complication rates compared with those undergoing open subpectoral biceps tenodesis. Additionally, both residual pain and Popeye deformity rates were similar between the 2 groups.

Arthroscopic Suprapectoral and Open Subpectoral Biceps Tenodeses Produce Similar Outcomes: A Randomized Prospective Analysis

PURPOSE

To directly compare subjective and objective outcomes of arthroscopic suprapectoral biceps tenodesis (ASPBT) below the bicipital groove and open subpectoral biceps tenodesis (OSPBT) performed with interference screw fixation.

METHODS

A total of 77 patients indicated for biceps tenodesis who met the inclusion and exclusion criteria were randomized into the ASPBT and OSPBT groups. All tenodesis procedures implemented PEEK (polyether ether ketone) interference screws. Patients underwent a clinical examination that included range of motion and strength assessment at 3, 6, and 12 months postoperatively. Patients completed the American Shoulder and Elbow Surgeons (ASES) shoulder score, Single Assessment Numeric Evaluation score, and Constant score preoperatively and at 6 and 12 months postoperatively.

RESULTS

Seventy-five patients were analyzed with a mean age of 50.3 ± 10.4 years and a mean body mass index of 28.9 ± 6.3. All patients had arthroscopic evidence of biceps pathology and underwent either an ASPBT (n = 37) or OSPBT (n = 38). The surgical time was significantly greater for ASPBT than for OSPBT (16.9 ± 8.4 minutes vs 9.8 ± 3.1 minutes, P < .001). One patient underwent conversion from the ASPBT group to the OSPBT group because of shearing of a severely attenuated tendon preventing an ASPBT. No significant difference (P > .05) was found in strength or anterior shoulder pain at 3 months, 6 months, and 1 year, and no significant difference (P > .05) was found in clinical outcome scores (ASES, Constant subjective, and Single Assessment Numeric Evaluation) between the 2 groups at 6 months and 1 year. The improvement in the ASES score exceeded the minimal clinically important difference (12 points) in both groups.

CONCLUSIONS

No differences in patient-reported outcome measures, functional outcomes, or complication rates were found after ASPBT compared with OSPBT. However, the results of this investigation must be interpreted with caution because this study may be underpowered to detect statistical differences.

Open subpectoral vs. arthroscopic proximal biceps tenodesis: A comparison study of clinical outcomes

The purpose of the present study was to compare the results of open subpectoral biceps tenodesis and arthroscopic proximal biceps tenodesis for treating long head of biceps (LHB) lesions. From January 2015 to June 2016, a total of 259 patients underwent LHB tenodesis surgery. Among them, 117 patients (60 females and 57 males) who met the inclusion and exclusion criteria were enrolled into the present study and were randomly divided into two groups, including an open subpectoral tenodesis group (OSPBT; n=62) and an arthroscopic proximal tenodesis group (ASPBT; n=55). All patients were followed up for at least 12 months. The demographic characteristics of each patient were recorded in detail. Moreover, clinical examinations of LHB lesions, such as shoulder range of motion (ROM), Visual Analog Scale (VAS) scores (0, no pain, to 10, most severe pain), American Shoulder and Elbow Surgeons (ASES) scores, and Constant-Murley shoulder outcome scores, were investigated prior to surgery, as well as 3, 6 and 12 months after surgery. Postoperative complications were also comprehensively investigated. There were no significant differences in sex, body mass index, dominant shoulder, duration of pain, injury type and operation time between the groups. The mean length of hospital stay in the ASPBT group was significantly lower than that of the OSPBT group (5.4±1.8 days vs. 9.3±2.9 days; P<0.05). The clinical outcomes, including shoulder ROMs, VAS scores, ASES scores and Constant-Murley shoulder outcome scores, were significantly improved after either OSPBT or ASPBT treatment. Specifically, the VAS score, incidence of postoperative stiffness and bicipital groove tenderness in the OSPBT group were significantly lower than those in the ASPBT group at 3 months post-surgery (P<0.05). Additionally, there were no significant difference in the improvement of other clinical outcomes and postoperative complications between the two groups. ASPBT and OSPBT were both effective and safe techniques for treating LHB lesions. However, tenderness of the bicipital groove was more common in the early stages of recovery post-surgery in the ASPBT group, which may be related to tendinitis of the LHB in the bicipital groove.

[Modern treatment strategies for the long head of the biceps tendon]

The long head of the biceps and the biceps pulley sling are prone to acute or degenerative injury. As they both were identified as major pain generators, adequate diagnosis and treatment is vital for successful treatment of shoulder pain. Although the basic principles to address either pathology have not changed over the last decades, new trends have evolved to simplify surgical options. SLAP (superior labral tear from anterior to posterior) repair is seen more restrictive and is mostly performed in young individuals, whereas tenotomy or tenodesis are more often used in patients over 30. The long head of the biceps and pulley lesions are treated with either tenotomy or tenodesis. Surgical techniques for tenodesis are especially less invasive using current implants. Tenodesis is performed either intraarticular, supra- or subpectoral with tenodesis screws or suture anchors. Soft tissue tenodesis has become unpopular over the last decade. Surgical treatment of the long head of the biceps pathologies allows highly satisfying results if the indication is chosen thoroughly.

Predictive Factors and the Duration to Pre-Injury Work Status Following Biceps Tenodesis

PURPOSE

To determine when patients return to work after biceps tenodesis stratified by the preinjury level of work-intensity and to identify predictive measures of return to work.

METHODS

Patients undergoing biceps tenodesis between 2014 and 2017 were reviewed. Patients receiving concomitant rotator cuff repair or arthroplasty, revision biceps tenodesis, or unemployment before the procedure were excluded. Patient-acceptable symptom state (PASS), substantial clinical benefit, and minimal clinically important difference were calculated for the American Shoulder Elbow Society (ASES) score, subjective Constant-Murley score (CMS), and Single Assessment Numerical Evaluation (SANE) using the anchor-based and distribution-based approach. Preoperative outcome scores were analyzed to determine their predictive power of return to work using receiver operator curve area under the curve (AUC) analysis. Multivariate logistical analysis assessed predictive variables of return to work.

RESULTS

Seventy-nine percent of patients were able to return to work without permanent restrictions at an average of 5.4 ± 2.8 months after biceps tenodesis. Return to work status for sedentary, light, moderate, and heavy duties were 100%, 85%, 71%, and 69%, respectively. Return to work was associated with achieving PASS for the ASES and SANE questionnaires (P = .006, .003, respectively) but not for the CMS (P = .768). On multivariate analysis, there were no preoperative or intraoperative variables that were predictive of return to work in full capacity. The preoperative Short Form-12 mental component score (>59.4, AUC = 71.2%) was predictive of returning to work.

CONCLUSIONS

After biceps tenodesis, most patients were able to return to work at an average of 5.4 ± 2.8 months. Furthermore, there were no demographic or intraoperative variables that were predictive of return to work. Work intensity was not correlated with an increased duration of return to work. Achieving PASS on the ASES and SANE questionnaires was predictive of return to work.

Biceps Tenodesis Is a Viable Option for Management of Proximal Biceps Injuries in Patients Less Than 25 Years of Age

PURPOSE

To evaluate outcomes after biceps tenodesis performed in patients younger than 25 years, to evaluate reoperations and complications in this population, and to critically appraise return to preinjury level of play for this population.

METHODS

Forty-five consecutive patients younger than 25 years underwent subpectoral biceps tenodesis for biceps tendinopathy or biceps-labral complex injuries including SLAP tears. Biceps tenodesis was performed using an interference screw technique. Patients with a minimum 2-year follow-up were analyzed. Functional outcomes were assessed with the visual analog scale score, American Shoulder and Elbow Surgeons (ASES) score, ASES functional score, Simple Shoulder Test score, and range of motion. Activity level and return to sport were followed postoperatively.

RESULTS

Of the 45 patients younger than 25 years who underwent biceps tenodesis, 36 (80%) were available for follow-up at a minimum of 2 years, with a mean age of 19.8 years and mean follow-up period of 38.6 months. Of these 36 patients, 34 (94%) were athletes, with 20 patients playing at collegiate level. All clinical outcome scores improved, with the ASES score improving from 54.7 to 81.7, the ASES functional score improving from 17.5 to 25.1, and the Simple Shoulder Test score improving from 7.4 to 10.1 (P < .001). At the time of follow-up, 4 patients (11%) had undergone revision surgery for other injuries. Of the 34 athletes, 25 (73%) returned to sports, with 19 returning at the same level and 6 returning at a lower level of play; 77% of overhead athletes returned to sports.

CONCLUSIONS

When indicated, biceps tenodesis offers an alternative to SLAP repair in young patients. Biceps tenodesis in patients younger than 25 years yields satisfactory outcomes, with two-thirds of patients returning to sport and a low revision rate.

Editorial Commentary: Is Arthroscopic In Situ Repair Effective for Long-Term Functional Recovery and Pain Relief in Symptomatic Partial Rotator Cuff Tears?

Currently, although most evidence suggests that surgery is effective in treating symptomatic partial-thickness rotator cuff tears in patients with failure of nonoperative management and with a tear of more than 50% of the tendon thickness, there is little consensus on the best method of repair. Some surgeons would advocate completing the tear and repairing it, whereas others would advocate performing in situ repair. In our opinion, it is important to also consider treating the long head of the biceps tendon, which is frequently a source of pain at the time of or after surgery.

Blood supply in the bicipital groove: A histological analysis

The vascular anatomy in the closed bicipital groove with the long head of the biceps brachii muscle tendon (LHBT), its mesotenon and the transverse ligament intact has not been analyzed on a histological level yet. An anatomic dissection and histologic study was conducted by using 24 cadaveric formaldehyde fixated shoulders. The bicipital groove including the LHBT and its intact sheath was cut en-bloc, fixated, sliced in 7 μm sections, Azan stained and the vascular anatomy analyzed under light microscopy. Each sideward branch deriving from the main ascending branches of the anterior humeral circumflex artery (ACHA) in the mesotenon of the LHBT was identified and followed through multiple sections to identify its direction and area of supply. Per specimen, a mean of 2.71±1.85 branches could be identified running through the soft tissue of the mesotenon towards the osseous walls of the groove. Of the total 65 arterial branches in all specimens, 22 (33.8%) were running into the medial wall of the groove and 40 (61.5%) into the lateral wall (P<0.01). The results indicate that branches of the ACHA in the mesotenon of the LHBT provide blood supply not only to the tendon but to the osseous bicipital groove as well and here significantly more to the lateral than to the medial osseous wall. In addition, Pacini-like mechanoreceptors could be identified in the mesotenon in 9 (37.5%) of the specimens which has not been described up to now.

Biceps tenodesis versus biceps tenotomy for biceps tendinitis without rotator cuff tears

Disorders of the long head of the biceps tendon (LHB) are a well-recognised cause of shoulder pain despite the function of the long head of the biceps remaining poorly understood. There has been a dramatic rise in the number of biceps tenodesis procedures being performed in the last decade. This may partly be attributed to concerns regarding residual cosmetic deformity and pain after biceps tenotomy though there is little evidence to suggest that functional outcomes of tenodesis are superior to biceps tenotomy. Current literature focuses on LHB disorders with concomitant rotator cuff tears. The aim of this review is to discuss the anatomy of the LHB, the pathogenesis of tendinopathy of the LHB, indications of biceps tenodesis and tenotomy and compare the current literature on the functional outcomes of these procedures for LHB disorders in the absence of rotator cuff tears.

Arthroscopic Management of Glenohumeral Arthritis: A Joint Preservation Approach

Treatment of young, active patients with primary glenohumeral osteoarthritis (GHOA) is challenging because shoulder arthroplasty may not be ideal in this population. In the past two decades, joint-preserving arthroscopic management options for GHOA, including débridement, have been used to treat different pathologies related to GHOA to reduce pain, to improve function, and to delay or even avoid arthroplasty. Key aspects of comprehensively addressing GHOA arthroscopically include chondroplasty, synovectomy, loose body removal, humeral osteoplasty with excision of the goat's beard osteophyte, capsular release, subacromial and subcoracoid decompression, axillary nerve decompression, and biceps tenodesis. Although data are still emerging, clinical studies report that an arthroscopic approach to glenohumeral arthritis using these various procedures reduces pain, improves function, and improves clinical outcome scores in the short- to mid-term follow-up period. Additional high-level studies are warranted to evaluate long-term outcomes and durability following this procedure.

Radiologic and Histologic Evaluation of Proximal Bicep Pathology in Patients With Chronic Biceps Tendinopathy Undergoing Open Subpectoral Biceps Tenodesis

PURPOSE

To correlate preoperative magnetic resonance imaging (MRI) and intraoperative anatomic findings within the proximal long head biceps tendon to histologic evaluation of 3 separate zones of the tendon in patients with chronic biceps tendinopathy.

METHODS

Sixteen patients with chronic biceps tendinopathy were treated with open subpectoral biceps tenodesis. Preoperative MRI tendon grading was as follows: normal tendon, increased signal, tendon splitting, incomplete/complete tear. The removed portion of the biceps tendon was split into 3 segments: zone 1, 0-3.5 cm from the labral insertion; zone 2, 3.5-6.5 cm; and zone 3, 6.5-9 cm, and was histologically evaluated using the Bonar score. Tenosynovium adjacent to the tendon was assessed histologically using the Osteoarthritis Research Society International score. CD31, CD3, and CD79a immunohistochemistries were conducted to determine vascularization, T-cell infiltrates, and B-cell infiltrates, respectively. Analysis of variance and Pearson correlations were performed for statistical analysis.

RESULTS

Preoperative MRI showed no significant differences in tendon appearance between zones 1-3. Intraoperative findings included nonspecific degenerative SLAP tears or mild/moderate biceps tenosynovitis in all cases. Significantly (P < .001) higher Bonar scores were noted for tendon in zones 1 (7.9 ± 1.8) and 2 (7.3 ± 1.5) compared with zone 3 (5.0 ± 1.1). Cell morphology scores in zone 1 (1.9 ± 0.4) and zone 2 (1.5 ± 0.6) were significantly higher than that in zone 3 (0.8 ± 0.3) (P < .05). Inflammatory tenosynovium showed weak correlation with tendon changes in zone 1 (r = 0.08), zone 2 (r = 0.03), or zone 3 (r = 0.1).

CONCLUSIONS

In patients with chronic long head biceps tendinopathy who underwent open subpectoral tenodesis, MRI and intraoperative assessment did not show significant structural abnormalities within the tendon despite significant histopathologic changes. Severity of tendon histopathology was more pronounced in the proximal and mid-portions of the tendon.

CLINICAL RELEVANCE

Proximal versus distal biceps tenodesis is a subject of frequent debate. This study contributes to the ongoing evaluation of the characteristics of the proximal biceps in this type of pathologic condition.

Arthroscopic Suprapectoral Biceps Tenodesis With Tenodesis Screw

There are many methods for long head of the biceps tendon (LHBT) tenodesis, but a consensus on a superior method has yet to be met. In this article, we introduce a method for arthroscopic suprapectoral biceps tenodesis using a tenodesis screw in the bicipital tunnel. The intra-articular portion of the biceps tendon is transected. The subdeltoid space is then viewed via a lateral portal, and the tendon is mobilized from the bicipital tunnel. The tendon is retrieved through the anterior portal, and 5 whipstitch passes and a second distal stitch are placed. Three of the suture tails are passed through the tenodesis screwdriver, and the tendon is maneuvered to the previously reamed bone socket located 1.5 cm superior to the pec tendon, just inferior to the bicipital groove. Once the tenodesis screw is fixated in sufficient bone stock, 5 alternating half hitches reinforce the construct by creating a closed loop through the screw. This described technique allows full visualization of the LHBT dissection and tenodesis throughout the procedure. Additionally, this technique provides a method to incorporate whipstitching with an arthroscopic tenodesis screw to provide additional strength to tendon fixation.

Subpectoral Biceps Tenodesis for Treatment of Isolated Type II SLAP Lesions in a Young and Active Population

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.

Five-Year Outcomes After Arthroscopic Repair of Partial-Thickness Supraspinatus Tears

PURPOSE

To investigate clinical outcomes in patients who underwent arthroscopic repair of isolated partial-thickness rotator cuff tears (PTRCTs) of the supraspinatus tendon with a minimum follow-up period of 5 years.

METHODS

All patients who had undergone arthroscopic repair of isolated PTRCTs at least 5 years earlier were included. Preoperatively and postoperatively, the American Shoulder and Elbow Surgeons, QuickDASH (short version of Disabilities of the Arm, Shoulder and Hand questionnaire), and Short Form 12 Physical Component Summary scores were collected, along with postoperative satisfaction (10-point scale) and return to activity. The associations between (1) patient age and outcome scores and (2) location of partial-thickness tear (articular vs bursal sided) and outcome scores were evaluated. Failure was defined as revision surgery of the rotator cuff repair.

RESULTS

The study included 24 shoulders (24 patients comprising 9 women and 15 men). Follow-up data were available on 20 shoulders (7 women and 13 men, 83% follow-up) at a mean of 6 ± 1 years postoperatively. The mean age at index surgery was 55 ± 11 years; 6 bursal- and 14 articular-sided tears were repaired. No patient required revision surgery. All scores significantly improved from preoperatively to postoperatively (P < .05); the median satisfaction rating (1, not satisfied; 10, completely satisfied) was 10 (range, 1-10). Neither patient age nor tear location correlated with outcome scores (P > .05). Seventeen patients indicated that they participated in previous recreational activity. Of these patients, 13 (76%) returned to the original level or a similar level of activity, 3 (18%) returned to activity at a lower level, and only 1 (6%) indicated an inability to return to activity.

CONCLUSIONS

Patients undergoing arthroscopic repair of PTRCTs can expect excellent clinical outcomes with low failure rates at midterm follow-up given that no patient progressed to revision rotator cuff repair during follow-up. The return-to-activity rate was very high after repair of isolated PTRCTs. Neither patient age nor tear location was associated with outcome scores.
