Arthroscopic repair of anterosuperior rotator cuff tears combined with open biceps tenodesis

mRNA and long non-coding RNA expression profiles of rotator cuff tear patients reveal inflammatory features in long head of biceps tendon

Background

This study aimed to identify the differentially expressed mRNAs and lncRNAs in inflammatory long head of biceps tendon (LHBT) of rotator cuff tear (RCT) patients and further explore the function and potential targets of differentially expressed lncRNAs in biceps tendon pathology.

Methods

Human gene expression microarray was made between 3 inflammatory LHBT samples and 3 normal LHBT samples from RCT patients. GO analysis and KEGG pathway analysis were performed to annotate the function of differentially expressed mRNAs. The real-time quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was admitted to verify their expression. LncRNA-mRNA co-expression network, cis-acting element, trans-acting element and transcription factor (TF) regulation analysis were constructed to predict the potential molecular regulatory mechanisms and targets for LHB tendinitis.

Results

103 differentially expressed lncRNAs and mRNAs, of which 75 were up-regulated and 28 were down-regulated, were detected to be differentially expressed in LHBT. The expressions of 4 most differentially expressed lncRNAs (A2MP1, LOC100996671, COL6A4P, lnc-LRCH1-5) were confirmed by qRT-PCR. GO functional analysis indicated that related lncRNAs and mRNAs were involved in the biological processes of regulation of innate immune response, neutrophil chemotaxis, interleukin-1 cell response and others. KEGG pathway analysis indicated that related lncRNAs and mRNAs were involved in MAPK signaling pathway, NF-kappa B signaling pathway, cAMP signaling pathway and others. TF regulation analysis revealed that COL6A4P2, A2MP1 and LOC100996671 target NFKB2.

Conclusions

LlncRNA-COL6A4P2, A2MP1 and LOC100996671 may regulate the inflammation of LHBT in RCT patients through NFKB2/NF-kappa B signaling pathway, and preliminarily revealed the pathological molecular mechanism of tendinitis of LHBT.

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.

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.

The rate and reporting of fracture after biceps tenodesis: A systematic review

BACKGROUND

The purpose of this systematic review was to (1) define the cumulative humerus fracture rate after BT and (2) compare how often fracture rate was reported compared to other complications.

METHODS

A systematic review was performed using the PRISMA guidelines.

RESULTS

39 studies reported complications and 30 reported no complications. Of the 39 studies that reported complications, 5 studies reported fracture after BT (n = 669, cumulative incidence of 0.53%). The overall non-fracture complication rate was 12.9%.

DISCUSSION

Due to the relatively high incidence of fracture, surgeons should ensure that this complication is disclosed to patients undergoing BT.

Long Head of Biceps Tenotomy Is Not Inferior to Suprapectoral Tenodesis in Arthroscopic Repair of Nontraumatic Rotator Cuff Tears: A Multicenter, Non-inferiority, Randomized, Controlled Clinical Trial

PURPOSE

To determine if long head of the biceps (LHB) tenotomy is not inferior to suprapectoral LHB tenodesis when performed in conjunction with arthroscopic repair of small- to medium-sized nontraumatic rotator cuff tears.

METHODS

This multicenter, randomized, non-inferiority trial recruited 100 participants older than 50 years who had a supraspinatus and/or infraspinatus tear sagittally smaller than 3 cm and arthroscopically confirmed LHB pathology. During arthroscopic rotator cuff repair, we randomized 48 patients to undergo suprapectoral LHB tenodesis and 52 patients to undergo LHB tenotomy. Data were collected preoperatively and at 6 weeks, 3 months, and 1 year postoperatively. The primary outcome was non-inferiority of the Constant-Murley score (CMS) at 1-year follow-up. Secondary outcomes included the Dutch Oxford Shoulder Score; Disabilities of the Arm, Shoulder and Hand questionnaire; Popeye deformity; elbow flexion strength index; arm cramping pain; and quality of life (EQ-5D score). The integrity of the rotator cuff repair was assessed with magnetic resonance imaging. Differences between intervention groups were analyzed by mixed modeling.

RESULTS

The mean CMS in the LHB tenotomy group improved from 44 (95% confidence interval [CI], 39-48) to 73 (95% CI, 68-79). In patients with LHB tenodesis, the mean CMS improved from 42 (95% CI, 37-48) to 78 (95% CI, 74-82). The difference between groups at 1-year follow-up was 4.8 (97.5% CI, -∞ to 11.4), with a P value for non-inferiority of .06. The secondary outcomes also improved over time, with no remarkable differences between groups. A Popeye deformity occurred in 33% of tenodesis patients and 47% of tenotomy patients (P = .17). Tenotomy was performed with a shorter operative time (73 minutes vs 82 minutes, P = .03). Magnetic resonance imaging showed a recurrent rotator cuff tear in 20% of all cases.

CONCLUSIONS

Although statistically "inconclusive" regarding non-inferiority of the CMS at 1-year follow-up, any observed differences between patients with LHB tenotomy and those with LHB tenodesis in all outcome scores were small.

Early success of the arthroscopic-assisted locked loop suprapectoral biceps tenodesis

Background

There is wide variability in surgical technique for biceps tenodesis. Prior biomechanical studies have demonstrated superior ultimate and fatigue strength with a Krakow-type locked loop when compared with simple suture and lasso-loop configurations; however, this had not yet been clinically studied. The purpose of this study was to assess the short-term results an arthroscopic-assisted locked loop (ALL) suprapectoral biceps tenodesis technique.

Methods

All patients who underwent an ALL suprapectoral biceps tenodesis by a single surgeon from 2012 and 2019 with a minimum of 12-month follow-up were analyzed. Data collected included demographics, surgical indications, concomitant operative procedures, and postoperative complications of anterior shoulder "groove" pain, "Popeye deformity," biceps muscle cramping pain, and need for revision surgery.

Results

Forty patients who underwent an ALL suprapectoral biceps tenodesis met inclusion criteria. Patients were 55.6 ± 8.6 years of age, consisting of 28 men (57%) and 21 women (43%). The median follow-up was 19.3 months. At the latest follow-up, 1 (2%) patient had anterior shoulder "groove" pain, and no patients had a Popeye deformity or biceps muscle cramping. There were no revision biceps tenodesis procedures.

Conclusion

The ALL suprapectoral biceps tenodesis technique results in a low incidence of postoperative complications. At a short-term follow-up of 1 year, no patients had reoperations or revisions for failed biceps tenodesis. Groove pain was nearly absent in this series of patients.

Are Implant Choice and Surgical Approach Associated With Biceps Tenodesis Construct Strength? A Systematic Review and Meta-regression

BACKGROUND

Despite the increasing use of biceps tenodesis, there is a lack of consensus regarding optimal implant choice (suture anchor vs interference screw) and implant placement (suprapectoral vs subpectoral).

PURPOSE/HYPOTHESIS

The purpose was to determine the associations of procedural parameters with the biomechanical performance of biceps tenodesis constructs. The authors hypothesized that ultimate failure load (UFL) would not differ between sub- and suprapectoral repairs or between interference screw and suture anchor constructs and that the number of implants and number of sutures would be positively associated with construct strength.

STUDY DESIGN

Meta-analysis.

METHODS

The authors conducted a systematic literature search for studies that measured the biomechanical performance of biceps tenodesis repairs in human cadaveric specimens. Two independent reviewers extracted data from studies that met the inclusion criteria. Meta-regression was then performed on the pooled data set. Outcome variables were UFL and mode of failure. Procedural parameters (fixation type, fixation site, implant diameter, and numbers of implants and sutures used) were included as covariates. Twenty-five biomechanical studies, representing 494 cadaveric specimens, met the inclusion criteria.

RESULTS

The use of interference screws (vs suture anchors) was associated with a mean 86 N-greater UFL (95% CI, 34-138 N; P = .002). Each additional suture used to attach the tendon to the implant was associated with a mean 53 N-greater UFL (95% CI, 24-81 N; P = .001). Multivariate analysis found no significant association between fixation site and UFL. Finally, the use of suture anchors and fewer number of sutures were both independently associated with lower odds of native tissue failure as opposed to implant pullout.

CONCLUSION

These findings suggest that fixation with interference screws, rather than suture anchors, and the use of more sutures are associated with greater biceps tenodesis strength, as well as higher odds of native tissue failure versus implant pullout. Although constructs with suture anchors show inferior UFL compared with those with interference screws, incorporation of additional sutures may increase the strength of suture anchor constructs. Supra- and subpectoral repairs provide equivalent biomechanical strength when controlling for potential confounders.

Increased reoperation rates among patients undergoing shoulder arthroscopy with concomitant biceps tenodesis

Background

The purpose of this study was to determine whether patients undergoing any shoulder arthroscopic procedure with concomitant biceps tenodesis have higher reoperation and complication rates vs. patients undergoing shoulder arthroscopy without concomitant biceps tenodesis.

Methods

A large database was queried for patients undergoing shoulder arthroscopy, identified by Current Procedural Terminology code. Only records indicating the laterality of the procedure were included. Patients were divided into 3 cohorts: arthroscopic shoulder surgery without concomitant biceps tenodesis (group 1), surgery with arthroscopic biceps tenodesis (group 2), and surgery with open biceps tenodesis (group 3). Reoperations on the same shoulder, as well as medical or surgical complications (by International Classification of Diseases, Ninth Revision code) during the 30-day postoperative period, were determined. Multivariate logistic regression was used to control for differences in age, sex, and Charlson Comorbidity Index between groups.

Results

We identified 62,461 patients (54.3% male patients) in the database who underwent shoulder arthroscopy, with 51,773 patients in group 1, 7134 patients in group 2, and 3554 patients in group 3. Overall, 3134 patients (5.0%) underwent a shoulder arthroscopy reoperation. With adjustment for age, sex, and Charlson Comorbidity Index, the biceps intervention groups demonstrated a significantly higher overall reoperation rate (odds ratio, 1.3 [95% confidence interval, 1.2-1.5]; P < .001). Patients undergoing biceps tenodesis had a lower adjusted overall 30-day complication rate vs. those not undergoing tenodesis (odds ratio, 0.82 [95% confidence interval, 0.79-0.86]; P < .001).

Conclusion

Reoperation rates were significantly higher in patients undergoing shoulder arthroscopy with biceps tenodesis than in patients undergoing shoulder arthroscopy without biceps tenodesis. Both the arthroscopic and open tenodesis groups had significantly lower complication rates.

Case-control comparison of "in-the-groove" and lateral-row arthroscopic biceps tenodesis with concomitant rotator cuff repair

Background

Lateral-row (LR) arthroscopic biceps tenodesis (BT) has been described as a technique using an LR rotator cuff repair (RCR) anchor for biceps fixation. This technique has not been compared with other BT techniques. The purpose of this study was to compare the clinical outcomes of patients undergoing a suprapectoral "in-the-groove" arthroscopic BT and patients treated with an LR tenodesis performed in conjunction with arthroscopic RCR.

Methods

Patients undergoing arthroscopic BT in the setting of an arthroscopic RCR were evaluated preoperatively and at a minimum of 12 months' follow-up. Patients who underwent an in-the-groove BT were matched 1:1 to patients who underwent an LR BT based on age at surgery and size of the rotator cuff tear using the Patte classification. Comparisons made included age, sex, body mass index, patient-reported outcome measures, range of motion, and patient satisfaction.

Results

There were 82 patients (41 in each group) who met the inclusion criteria, with an average follow-up period of 33 months and average age of 61 years. By use of the Patte classification, there were 20 matched pairs with stage 1 tears, 11 matched pairs with stage 2 tears, and 10 matched pairs with stage 3 tears. Comparisons of the 2 cohorts revealed no differences in preoperative or postoperative motion, patient-reported outcome measures, or patient satisfaction. Furthermore, no differences were found in overall improvements in motion or outcome measures, as well as overall satisfaction.

Conclusions

Patients undergoing simultaneous RCR and BT demonstrate similar patient-reported and objective outcomes for both LR tenodesis and in-the-groove tenodesis techniques.

Rotator cuff tear with concomitant long head of biceps tendon (LHBT) degeneration: what is the preferred choice? Open subpectoral versus arthroscopic intraarticular tenodesis

BACKGROUND

Lesions associated with the biceps tendon are commonly detected during arthroscopic repair of rotator cuff tears. Acquiring a preferable technique to repair both cuff and long head of biceps tendon (LHBT) lesions was the aim of several recent studies. This study aimed to compare clinical and functional outcomes of open subpectoral versus arthroscopic intraarticular tenodesis in patients with repairable rotator cuff tear associated with LHBT degeneration.

PATIENTS AND METHODS

In this randomized clinical trial, 60 eligible candidates for arthroscopic rotator cuff repair (mean age 55.7 ± 6.9 years) were allocated to a control group (open subpectoral, SP) or intervention group (intraarticular, IA). In the IA group, an anchor suture was used for both rotator cuff repair and LHBT tenodesis. In the SP group, after arthroscopic repair of the rotator cuff, subpectoral tenodesis of LHBT was performed using an interference screw. Patients were evaluated for 2 years follow-up regarding pain intensity using the visual analogue scale (VAS) and shoulder function using the Constant Score and Simple Shoulder Test.

RESULTS

The two groups were similar with regard to demographic characteristics and preoperative evaluations (all P > 0.05). The functional status of both groups was improved, but not significantly differently so between the two groups (P = 0.1 and P = 0.4, respectively). Pain intensity decreased during the 2-year follow-up period, similarly so in the two groups. Patient satisfaction was also similar in the two groups.

CONCLUSION

Large and massive rotator cuff tears (tears > 3 cm) associated with LHBT pathologies benefited from intraarticular or subpectoral tenodesis similarly, with no differences in short- or mid-term results between these two techniques.

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 subscapularis repair using single-row mattress suture technique: clinical results and structural integrity

BACKGROUND

Rupture of the subscapularis (SSC) tendon, isolated or combined, is rare, and the treatment modalities are controversial. The purpose of this study was to evaluate, by magnetic resonance imaging (MRI), the clinical outcomes and structural integrity of the SSC tendon after all-arthroscopic repair with single-row mattress suture for isolated or combined SSC tendon tears.

METHODS

This study included 68 patients who underwent all-arthroscopic repair using single-row mattress suture for isolated or combined SSC tendon tears between April 2011 and January 2013. The patients were evaluated by the visual analog scale for pain, American Shoulder and Elbow Surgeons score, Constant shoulder score, and SSC muscle strength measurement. MRI was used for assessment of the postoperative integrity of the SSC tendon.

RESULTS

With a mean follow-up of 29.5 ± 4.0 months, the preoperative Constant shoulder and American Shoulder and Elbow Surgeons scores were 50.3 ± 21.0 and 46.6 ± 18.3, respectively, which improved at the last follow-up to 75.7 ± 16.6 and 81.3 ± 18.1, respectively, with statistical significance (P < .001). Belly-press and bear-hug test results showed some improvement in the last follow-up (>2 years) compared with the presurgical state (P = .125 and .650). A statistically significant SSC muscle strength deficit persisted in the postoperative state (P = .015). MRI evaluation showed a retear rate of 8.8%.

CONCLUSIONS

Arthroscopic repair of isolated or combined SSC tears with the single-row mattress suture technique results in significant clinical improvements and enduring tendon integrity, although SSC strength remains reduced from that on the normal side.

Management of Biceps Tendon Pathology: From the Glenoid to the Radial Tuberosity

Management of proximal and distal biceps tendon pathology is evolving. The long head of the biceps tendon, if inflamed, may be a pain-producing structure. In appropriately indicated patients, a symptomatic long head of the biceps tendon can be surgically managed via tenotomy, tenodesis, and/or superior labrum anterior to posterior repair. In some patients, primary superior labrum anterior to posterior pathology can be managed via biceps tenodesis. Determining which procedure is most appropriate and which technique and implant are preferred for a given patient with biceps tendon pathology is controversial. Less debate exists with regard to the timing of distal biceps tendon repair; however, considerable controversy exists with regard to selection of an appropriate surgical technique and implant. In addition, the treatment of patients with a chronic and/or retracted distal biceps tendon tear and patients in whom distal biceps tendon repair fails is extremely challenging. Orthopaedic surgeons should understand the anatomy of, nonsurgical and surgical treatment options for, and outcomes of patients with proximal or distal biceps tendon pathology.

Clinical and sonographic evaluation of subpectoral biceps tenodesis with a dual suture anchor technique demonstrates improved outcomes and a low failure rate at a minimum 2-year follow-up

INTRODUCTION

The purpose of this study was to evaluate the clinical outcomes and integrity of an open subpectoral biceps tenodesis using a dual suture anchor construct.

MATERIALS AND METHODS

Patients with at least 2 years of follow-up were retrospectively evaluated for simple shoulder test (SST), American Shoulder and Elbow Surgeons (ASES) score, and visual analog scales (VAS) for pain, function and satisfaction. A physical exam assessed shoulder range of motion and elbow strength. Ultrasonography visualized construct integrity.

RESULTS

Of 43 eligible patients, 36 completed questionnaire evaluation and 22 completed an additional physical examination. Indications included superior labral anterior-posterior (SLAP) lesions (4), partial thickness tears (6), instability (6), and tenosynovitis of the biceps tendon (20). Eighteen patients (50%) had an associated rotator cuff tear. Patient-reported outcomes improved pre- vs postoperatively: ASES score (45.4 vs 78.6, P < 0.001), SST (5.1 vs 9.6, P < 0.001), pain-VAS (4.8 vs 2.0, P < 0.001), and function-VAS (4.9 vs 2.3, P < 0.001). Satisfaction-VAS was 8.3 postoperatively. Patient-reported outcomes did not differ for patients with an associated rotator cuff tear compared to those without (P ≥ 0.427). None of the physical exam measures were lower on the operative side compared to the healthy side (P ≥ 0.516). Sonographic evaluation revealed preserved integrity of the tenodesis construct in all cases. No complications were noted.

CONCLUSIONS

Subpectoral biceps tenodesis utilizing a dual suture anchor technique is a treatment option for SLAP lesions, partial thickness tears, subluxation, and tenosynovitis of the long head of the biceps with high rates of postoperative patient satisfaction, a low failure rate, and improved outcome scores. The presence of a concomitant rotator cuff tear did not influence clinical outcomes.

Functional Recovery After Rotator Cuff Repair: The Role of Biceps Surgery

CONTEXT

Surgical cuff repair is recommended in a full-thickness rotator cuff tear when nonoperative treatment fails. Surgical cuff repair can include surgery of the long head of the biceps when concomitant biceps pathology is present. However, the studies executed up till now have not yet clearly defined if additional biceps surgery affects the shoulder functionality in patients who underwent rotator cuff repair.

OBJECTIVE

To verify if the concomitant biceps surgery prejudices shoulder functionality during the short-term period in rotator cuff repair patients.

DESIGN

Prospective and observational study.

SETTING

Outpatient service for rehabilitation.

PATIENTS

Ninety-three consecutive patients who had undergone surgery for full-thickness symptomatic rotator cuff tear were enrolled for rehabilitation; 25 underwent rotator cuff repair and tendon biceps surgery (ABS), while 68 underwent rotator cuff repair only (RCR).

INTERVENTIONS

Motor rehabilitation after surgical treatment of rotator cuff repair.

MEASURES

Final Constant score was used as primary outcome measure, and efficiency and effectiveness in Constant score were evaluated both at the end of the last cycle of rehabilitation and 6 mo postsurgery.

RESULTS

Patients with rotator cuff repair and tendon biceps surgery had lower final scores (36.5 ± 12.0 vs 49.3 ± 13.0, P < .001), effectiveness (40.6 ± 18.0 vs 60.3 ± 20.0, P < .001), and efficiency (0.80 ± 0.5 vs 1.19 ± 0.6, P = .010) in Constant score than those with rotator cuff repair only at the end of rehabilitation. Moreover, they had a lower final score (53.3 ± 14.0 vs 64.5 ± 10.0, P < .001) and effectiveness (66.9 ± 21.0 vs 84.0 ± 16, P < .001) in Constant score 6 mo postsurgery. Gender was a determinant of final score, efficiency, and effectiveness in Constant score at the end of the rehabilitation period, while tendon biceps surgery was a determinant of final score and effectiveness in Constant score at the end of the rehabilitation period and at 6 mo postsurgery.

CONCLUSIONS

This study highlights that concomitant tendon biceps surgery negatively affects functional outcome of patients who underwent rotator cuff repair and is an important determinant of shoulder functionality in the first 6 mo postsurgery.

All-Extra-articular Repair of Anterosuperior Rotator Cuff Tears

Anterosuperior rotator cuff tears involve the subscapularis tendon, supraspinatus tendon, and rotator interval. The long head of the biceps is usually affected and unstable in these complex lesions. Arthroscopic repair of anterosuperior rotator cuff tears often consists of 2 different procedures. Whereas the subscapularis tendon is reconstructed under intra-articular visualization, the supraspinatus tendon is reconstructed under extra-articular visualization. The rotator interval is often sacrificed to improve visualization and instrumentation. The presented technique uses an all-extra-articular approach, which helps to reconstruct these complex rotator cuff lesions in their whole extent without switching from the inside to the outside of the shoulder joint. The preservation of the rotator interval leads to a more stable and anatomic reconstruction.

Subscapularis tendon tears: Management and arthroscopic repair

Tears of the subscapularis tendon have been under-recognised until recently. Therefore, a high index of suspicion is essential for diagnosis.A directed physical examination, including the lift-off, belly-press and increased passive external rotation can help identify tears of the subscapularis.All planes on MR imaging should be carefully evaluated to identify tears of the subscapularis, retraction, atrophy and biceps pathology.Due to the tendency of the tendon to retract medially, acute and traumatic full-thickness tears should be repaired. Chronic tears without significant degeneration should be considered for repair if no contraindication exists.Arthroscopic repair can be performed using a 30-degree arthroscope and a laterally-based single row repair; one anchor for full thickness tears ⩽ 50% of tendon length and two anchors for those ⩾ 50% of tendon length.Biceps pathology, which is invariably present, should be addressed by tenotomy or tenodesis.Timing of post-operative rehabilitation is dictated by the size of the repair and the security of the repair construct. The stages of rehabilitation typically involve a period of immobilisation followed by range of movement exercises, with a delay in active internal rotation (IR) and strengthening in IR.

Ten-year clinical and anatomic follow-up after repair of anterosuperior rotator cuff tears: influence of the subscapularis

BACKGROUND

Anterosuperior rotator cuff tears are more frequent than expected. We report the results of a 10-year follow-up study after repair. Our hypothesis was that the extent of the subscapularis tear influenced the prognosis.

MATERIALS AND METHODS

The study population consisted of all 138 patients who underwent surgery in 14 participating centers in 2003 for full-thickness tears of the rotator cuff with lesions in the subscapularis and supraspinatus tendons. The patients were divided into 2 groups, depending on whether the subscapularis lesion affected only the superior half of the tendon (group A) or extended into the lower half (group B). Ninety-two patients (56 ± 7 years; 71 in group A and 21 in group B) were available for follow-up after 10 years (127 ± 16 months) with magnetic resonance imaging to evaluate tendon healing and muscle condition.

RESULTS

The mean Constant scores were 59 ± 16 before surgery and 77 ± 14 at follow-up (P = 1.7 × 10^-12). The retear rates were 25% for the supraspinatus and 13.5% for the subscapularis tendon. The clinical results for group A patients were better than those for group B. Severe fatty infiltration was observed more frequently in the subscapularis than in the supraspinatus muscle (27% vs. 12% of cases). Supraspinatus healing influenced subscapularis healing and fatty infiltration.

CONCLUSIONS

Repair of anterosuperior rotator cuff tears is satisfactory at 10 years, particularly if the subscapularis tear is not extensive. An extensive subscapularis tear is a negative prognosis factor. Postoperatively, fatty infiltration of the subscapularis muscle was frequently observed despite tendon healing.

Isolated Biceps Reflection Pulley Tears Treated With Subpectoral Biceps Tenodesis: Minimum 2-Year Outcomes

PURPOSE

To investigate if patients younger than 50 years old had improved functional outcomes after subpectoral biceps tenodesis (BT) for the treatment of biceps reflection pulley (BRP) lesions at minimum 2-year postoperative follow-up.

METHODS

Patients who had arthroscopically confirmed BRP tears that were treated with subpectoral BT and were at least 2 years out from surgery were included; patients were excluded if they had concomitant reconstructive or reparative procedures at index surgery. Patient-centered outcomes including return to activity, American Shoulder and Elbow Surgeons (ASES), Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH), and Short Form-12 Physical Component Summary (SF-12 PCS) scores, and patient satisfaction were collected. The pre- and postoperative scores were compared with a Wilcoxon test. Failure was defined as revision BT.

RESULTS

Between January 2006 and July 2014, of 1,184 patients who underwent open subpectoral BT, 14 patients (6 male, 8 female) with mean age 37 (range, 16-49 years) met the inclusion criteria. Minimum 2-year outcomes data were available for all 14 patients (100% follow-up). The mean follow-up was 3.6 ± 1.3 years. There were significant improvements postoperatively for all outcome scores (P = .017 ASES, P = .002 QuickDASH, P = .003 SF-12 PCS). There was no correlation between age and outcome scores (P > .05). Median patient satisfaction was 9 of 10. Five patients (36%) reported return to recreational activity with no modifications; 9 (64%) indicated a return to activity with modifications. The 5 patients who returned to recreational activity with no modification had significantly less time from initial injury/onset of symptoms until surgery in comparison with the 9 patients who modified their activity (P = .028). No complications or reoperations were reported.

CONCLUSIONS

Patients younger than 50 years old with a symptomatic isolated BRP lesion experienced excellent results, high return to recreational activity, little postoperative pain, and high degrees of satisfaction when treated with subpectoral BT.

All-Arthroscopic Modified Rotator Interval Slide for Massive Anterosuperior Cuff Tears Using the Subdeltoid Space: Surgical Technique and Early Results

BACKGROUND

Traditional intra-articular arthroscopic repair techniques for massive anterosuperior rotator cuff tears are technically demanding and necessitate sacrifice of the rotator interval to enable visualization. An interval slide allows mobilization through release of the medial aspect of the rotator interval, while leaving the lateral, bridging fibers intact.

QUESTIONS/PURPOSES

The purpose of this study was to report a novel, arthroscopic, open-equivalent technique using the subdeltoid space to address these tears along with early clinical results.

METHODS

A retrospective review of prospectively collected data identified 11 consecutive arthroscopic massive anterosuperior rotator cuff repairs with a concomitant biceps tenodesis performed by the senior surgeon using a uniform technique. Outcome measures included range of motion, visual analog scale for pain, rotator cuff strength, American Shoulder and Elbow Surgeons (ASES) outcome scale, and Short Form-12 (SF-12).

RESULTS

Average length of follow-up was 22.2 months (range 12.5-30.0 months). Visual analog scale (VAS) pain scores, ASES, and SF-12 all demonstrated significant improvement from pre-op to final follow-up from 6.2 to 0.9 (p < 0.05), 27.4 to 82.8 (p < 0.05), and 26.6 to 45.5 (p < 0.05) respectively. Average forward flexion improved from 145° to 160° (p < 0.05). Seven of the nine patients with a positive preoperative belly press had a negative test at final follow-up. Nine of the 10 patients with a positive lift off test demonstrated a negative test on final follow-up. Ninety-one percent reported they were satisfied with their outcome.

CONCLUSIONS

The described modified all-arthroscopic subdeltoid approach for anterosuperior cuff repairs enabled an open-equivalent interval slide technique that preserved the bridging lateral fibers of the rotator interval and demonstrated promising early-term clinical results.

Outcomes following long head of biceps tendon tenodesis

Lesions of the proximal long head of the biceps tendon (LHB) have been considered as a major cause of shoulder pain and dysfunction. The role of the LHB in causing pain has been a source of controversy for many years, and extensive literature is available discussing anatomy, function, pathology, and most importantly appropriate treatment. Despite this, there is a lack of consensus in the literature regarding the management of biceps-related pathology. Biceps tenotomy and tenodesis are common surgical treatment options when dealing with LHB-related pathology. In this review, a brief discussion on surgical options is provided while focusing on the different options for biceps tenodesis including outcomes and complications.

[Surgical treatment of anterosuperior impingement of the shoulder]

OBJECTIVE

Therapy of intraarticular lesions and elimination of structural risk factors for those suffering from clinical manifest anterosuperiorer impingement (ASI) of the shoulder. This includes as a maximum version the arthroscopic repair of supraspinatus (SST) and subscapularis tendon (SCT) tears with subsequent subpectoral tenodesis of the long head of the biceps tendon (LBT) and arthroscopic coracoplasty.

INDICATIONS

Clinical manifest anterosuperiorer impingement of the shoulder with anterior shoulder pain, failed conservative treatment and clear intraarticular damage in radiological imaging. This involves in detail lesions of the SST, SCT and damage to the LBT.

CONTRAINDICATIONS

Lack of structural intraarticular lesions or massive osteoarthritis. Persistent dysfunction of active and passive glenohumeral and scapulathoracal motion, due to neurologic deficits or stiff shoulder. A hypertrophic or deformed healed coracoid process is seen as a structural risk factor for suffering from ASI and should be addressed surgically when causing impingement.

SURGICAL TECHNIQUE

Arthroscopic tenotomy of the LBT with subsequent repair of the SST and SCT. Arthroscopic coracoplasty if indicated and subpectoral tenodesis of the long head of the biceps.

POSTOPERATIVE MANAGEMENT

No biceps activity and intermittent immobilization in sling for 6 weeks. Limitation of abduction, flexion and external rotation for 6 weeks depending on rotator cuff tendon repair. Start of sport-specific training after 3 months, over-head sports 6 months postoperatively.

RESULTS

The arthroscopic repair of anterosuperior rotator cuff tears provides reliable results for improvement in function, decreases in pain and improvement in shoulder scores. The overall rate of adverse events is low.

Functional and structural comparisons of the arthroscopic knotless double-row suture bridge and single-row repair for anterosuperior rotator cuff tears

BACKGROUND

We compared the outcomes of knotless double-row suture bridge and single-row repairs in patients undergoing arthroscopic repair for anterosuperior rotator cuff tears.

METHODS

We included 61 full-thickness anterosuperior rotator cuff tears treated by arthroscopic repair, namely, single-row repair (group 1: 25 shoulders; mean patient age, 64 years) and the knotless double-row suture bridge repair (group 2: 36 shoulders; mean patient age, 62 years). Preoperative and postoperative magnetic resonance imaging was performed for all shoulders. Clinical outcomes were evaluated for mean follow-up periods of 81 months (range, 72-96 months) in group 1 and 34 months (range, 24-42 months) in group 2, using the University of California, Los Angeles and Japanese Orthopaedic Association assessments.

RESULTS

At the final follow-up, both groups showed improvement in the average University of California, Los Angeles and Japanese Orthopaedic Association scores and range of motion, although no intergroup differences were observed. Both groups showed improved abduction strength, and the average score was higher in group 2 (P = .0112). The lift-off and belly-press test results were improved in both groups. Postoperatively, the incidence of positive lift-off tests tended to be lower (P = .075) and that of positive belly-press tests was lower in group 2, P = .049). The repair failure rate tended to be lower in group 2 (14% [5 of 36]) than in group 1 (32% [8 of 25]; P = .0839).

CONCLUSIONS

Arthroscopic knotless double-row suture bridge repair of anterosuperior rotator cuff tears yielded functional outcomes equivalent to those of single-row repair and may be useful for improving subscapularis function, abduction strength, and tendon healing.

Strength recovery after arthroscopic anterosuperior cuff repair: analysis of a consecutive series

PURPOSE

The purpose of this study was to look at the functional outcomes of arthroscopic repair of anterosuperior rotator cuff tears.

METHODS

Sixty-one patients who underwent arthroscopic repair of anterosuperior cuff tears were retrospectively reviewed. At a minimum 6 months of follow-up, shoulder functional outcome scores including the Constant score (CS), simple shoulder test (SST) and visual analogic scale (VAS) were collected. Strength recovery for supraspinatus and subscapularis was investigated.

RESULTS

All patients (mean age 59 ± 7) were available at a mean follow-up of 18 ± 7 months. The average CS improved from 30.8 ± 10.2 preoperatively to 76.5 ± 12.0 postoperatively, average SST from 2.6 ± 2.0 to 8.8 ± 2.9 and average VAS pain scale from 3.8 ± 1 to 0.5 ± 0.5 (p < 0.0001). Strength at belly-press and Jobe tests significantly improved (p < 0.0001). All patients with the exception of one were satisfied with the intervention.

CONCLUSIONS

Arthroscopic repair of anterosuperior rotator cuff tears provides a significant improvement in pain relief and shoulder function. Strength recovery is demonstrated in medium correlation with tendon healing.

A Systematic Review and Meta-analysis Comparing Clinical Outcomes After Concurrent Rotator Cuff Repair and Long Head Biceps Tenodesis or Tenotomy

Context:

A comparison of clinical outcomes after long head of biceps (LHB) tenotomy or tenodesis performed concurrently with rotator cuff repair (RCR) is of interest to physicians and patients.

Objective:

A systematic review of clinical outcome studies examining LHB tenotomy or tenodesis performed concurrently with RCR. Secondarily, perform a meta-analysis of data from comparative studies.

Data Sources:

MEDLINE (1946 to week 30 of 2013) and EMBASE (1980 to week 30 of 2013).

Study Selection:

Levels 1 through 4 studies reporting clinical outcomes of concurrent RCR and LHB tenotomy or tenodesis with minimum 1-year follow-up.

Study Design:

Systematic review and meta-analysis.

Level of Evidence:

Level 4.

Data Extraction:

Two independent reviewers identified eligible studies and applied the exclusion criteria. Clinical outcome data, including functional outcome score(s), biceps deformity and cramping, and patient satisfaction, were extracted. Clinical outcome data from included studies were pooled (weighted according to study size) and reported. A meta-analysis was performed only on outcomes extracted from comparative studies (α = 0.05).

Results:

Twelve studies (N = 565 patients; mean age, 61.3 years; 46.3% men) were included. Of these, 6 (N = 263) included RCR and LHB tenotomy and 9 (N = 302) included RCR and LHB tenodesis. A meta-analysis was performed on 3 comparative studies (levels 1 and 2), demonstrating that the postoperative Constant score at a mean follow-up of 25.5 months was significantly greater after tenodesis (92.8 [tenodesis] vs 90.6 [tenotomy], P < 0.01); however, this difference was less than the reported minimal clinically important difference of 10.4 points. Similarly, the rate of biceps deformity was significantly less after tenodesis (15.5% [tenotomy] vs 3.9% [tenodesis], P < 0.01); however, most patients were not bothered by it. There were no significant differences in the rate of biceps cramping or patient satisfaction.

Conclusion:

Although the postoperative Constant score and rate of biceps deformity favor LHB tenodesis statistically, the clinical significance appears negligible.

Arthroscopic proximal biceps tenodesis at the articular margin: evaluation of outcomes, complications, and revision rate

PURPOSE

The purpose of this study was to evaluate the incidence of residual pain, outcomes, and the revision rate of arthroscopic proximal biceps tenodesis high in the groove at the articular margin of the humeral head by interference screw fixation.

METHODS

Seven surgeons pooled data on patients who underwent an arthroscopic biceps tenodesis at the articular margin by interference screw fixation. All patients had a minimum of 50 weeks' follow-up. Preoperative and postoperative patient data including visual analog scale scores (obtained by all surgeons), objective shoulder scores (Simple Shoulder Test and University of California, Los Angeles scores obtained by 2 and 4 surgeons, respectively), and need for revision surgery (obtained by all surgeons) were retrospectively analyzed, the results are reported, and statistical analysis was performed.

RESULTS

After the application of our exclusion criteria, 1,083 patients were included in the analysis. The mean follow-up period was 136 weeks. The overall revision surgery rate for this group was 4.1% (44 of 1,083). Revision for biceps tenodesis-related issues was needed in only 4 cases (for a biceps tenodesis-related revision rate of 0.4%). Pain scores improved from 6.47 preoperatively to 1.08 postoperatively (P < .0001). University of California, Los Angeles scores improved from 14.9 preoperatively to 30.1 postoperatively (P < .0001), and Simple Shoulder Test scores improved from 2.7 preoperatively to 10.2 postoperatively (P < .0001).

CONCLUSIONS

Arthroscopic biceps tenodesis performed at the articular margin results in a low surgical revision rate, a low rate of residual pain, and significant improvement in objective shoulder outcome scores.

LEVEL OF EVIDENCE

Level IV, therapeutic case series.

Trends in long head biceps tenodesis

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 χ(2) 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.

Biomechanical analysis of subpectoral biceps tenodesis: effect of screw malpositioning on proximal humeral strength

BACKGROUND

Humeral fracture after subpectoral tenodesis of the long head of biceps tendon (LHB) is a rare but devastating complication.

PURPOSE

To determine whether malpositioned (laterally eccentric) tenodesis screw placement has an influence on humerus strength reduction compared with central placement.

STUDY DESIGN

Controlled laboratory study.

METHODS

Two groups, each consisting of 10 matched pairs of human humeri, were used for this study. Biceps tendons were fixed subpectorally with 8-mm screws in unicortical 8-mm sockets. In the first group, the socket was placed concentrically in the bicipital groove and the tendon was fixed with an interference screw. In the second group, the socket was malpositioned 30% eccentrically to the lateral (tension) side of the humerus. Contralateral humeri remained intact as positive controls. Specimens were aligned in 40° of abduction, and a uniaxial compressive force was applied to the humeral head until failure. Strength reduction was reported as percentage reduction in ultimate failure load between paired humeri. Relative defect size was calculated as a percentage of the total humeral width at the height of the tenodesis.

RESULTS

Laterally eccentric malpositioned biceps tenodeses significantly decreased humeral strength compared with intact (mean change, -25%; SD, 23%; P=.017), while concentrically placed biceps tenodeses did not (mean change, -10%; SD, 15%; P=.059). A linear regression between relative defect size and strength reduction in the malpositioned group showed a significant negative linear correlation (beta=-2.577; R2=0.423; P=.042).

CONCLUSION

Humeral fracture after subpectoral tenodesis of the LHB is a complication that may be minimized with careful surgical technique. Laterally eccentric malpositioned biceps tenodesis caused significant reduction (25%) in humeral strength, which might be clinically relevant and contribute to postsurgical humeral shaft fracture. Strength reduction was also significantly correlated with relative defect size. Surgeons using this technique should ensure central and orthogonal placement of the socket, especially in smaller individuals. This study lends biomechanical evidence to support the clinical procedure of a correctly, concentrically placed tenodesis screw.

CLINICAL RELEVANCE

These biomechanical results indicate that in a clinical setting, special attention should be drawn to patient selection for LHB tenodesis. This study reveals that central screw positioning is critical, particularly in high-impact and overhead athletes, as well as for patients with small humeral widths or osteoporotic bone quality. Alternative surgical options such as smaller screws or other fixation methods might be considered to diminish the postoperative risk of humeral fracture.

Arthroscopic suprapectoral and open subpectoral biceps tenodesis: a comparison of minimum 2-year clinical outcomes

BACKGROUND

While a vast body of literature exists describing biceps tenodesis techniques and evaluating the biomechanical aspects of tenodesis locations or various implants, little literature presents useful clinical outcomes to guide surgeons in their decision to perform a particular method of tenodesis.

PURPOSE/HYPOTHESIS

To compare the clinical outcomes of open subpectoral biceps tenodesis (OSPBT) and arthroscopic suprapectoral biceps tenodesis (ASPBT). Our null hypothesis was that both methods would yield satisfactory results with regard to shoulder and biceps function, postoperative shoulder scores, pain relief, and complications.

STUDY DESIGN

Cohort study; Level of evidence, 3.

METHODS

Patients who underwent either ASPBT or OSPBT for isolated superior labrum or long head of the biceps lesions with a minimum follow-up of 2 years were evaluated with several validated clinical outcome measures and physical examinations including range of motion and strength.

RESULTS

Between 2007 and 2011, a total of 82 patients met all inclusion and exclusion criteria, which included 32 patients with ASPBT and 50 patients with OSPBT; 27 of 32 (84.4%) patients with ASPBT and 35 of 50 (70.0%) patients with OSPBT completed clinical follow-up. Overall outcomes for both procedures were satisfactory. No significant differences were noted in postoperative Constant-Murley (ASPBT: 90.7; OSPBT: 91.8; P = .755), American Shoulder and Elbow Surgeons (ASPBT: 90.1; OSPBT: 88.4; P = .735), Single Assessment Numeric Evaluation (ASPBT: 87.4; OSPBT: 86.8; P = .901), Simple Shoulder Test (ASPBT: 10.4; OSPBT: 10.6; P = .762), long head of the biceps (ASPBT: 91.6; OSPBT: 93.6; P = .481), or Veterans RAND 36-Item Health Survey (ASPBT: 81.0; OSPBT: 80.1; P = .789) scores. No significant range of motion or strength differences was noted between the procedures.

CONCLUSION

Both ASPBT and OSPBT yield excellent clinical and functional results for the management of isolated superior labrum or long head of the biceps lesions. No significant differences in clinical outcomes as determined by several validated outcome measures were found between the 2 tenodesis methods, nor were any significant range of motion or strength deficits noted at a minimum 2 years postoperatively.

Increased incidence of postoperative stiffness after arthroscopic compared with open biceps tenodesis

PURPOSE

To determine the incidence of postoperative stiffness after open and arthroscopic biceps tenodesis, compare the incidence between each method, and determine relevant risk factors for its occurrence.

METHODS

A consecutive series of patients who underwent biceps tenodesis during a 3-year period were retrospectively reviewed.

RESULTS

We evaluated 249 patients, which included 143 who underwent open subpectoral tenodesis and 106 who underwent arthroscopic suprapectoral tenodesis. The mean overall follow-up period for the arthroscopic group was 9.9 months (range, 5.1 to 33.5 months). The mean overall follow-up period for the open group was 9.5 months (range, 4.7 to 49.2 months). There was no significant difference in overall follow-up duration between groups (P = .627). A significantly increased incidence of postoperative stiffness was found in the arthroscopic group compared with the open group (17.9% v 5.6%, P = .002). Within the arthroscopic group, patients with postoperative stiffness were more frequently female patients than those without stiffness (63.2% v 33.3%, P = .016) and were more likely to be smokers than those without stiffness (36.8% v 16.1%, P = .040). The tenodesis site was located significantly more proximal in the arthroscopic group of patients with postoperative stiffness compared with patients without postoperative stiffness (32.44 ± 7.8 mm from the top of the humeral head v 50.34 ± 7.8 mm, P < .0001).

CONCLUSIONS

Our results show a notably increased incidence of postoperative stiffness after arthroscopic suprapectoral biceps tenodesis compared with open subpectoral biceps tenodesis. This appears to occur more commonly in female patients and smokers and may have a relation to the position of the tenodesis, with a more superiorly placed tenodesis site being a potential influencing factor. On the basis of this series, this complication most commonly will improve over time and with symptom-based management.

The severity of the long head biceps tendinopathy in patients with chronic rotator cuff tears: macroscopic versus microscopic results

BACKGROUND

This study investigated the histopathology of the long head of biceps (LHB) tendon and correlated the findings with the macroscopic appearances of the LHB and the size of rotator cuff tears (RCTs) in patients with chronic RCTs.

METHODS

We compared biopsy specimens from LHBs in 34 patients with chronic RCTs and grossly normal LHBs in 8 patients undergoing shoulder hemiarthroplasty (controls). Duration of preoperative symptoms, the severity of RCTs, and macroscopic appearance of LHBs were recorded, classified, and compared with the histologic grading and apoptosis index of terminal deoxynucleotide transferase-mediated biotin-deoxy uridine triphosphate nick-end labeling (TUNEL) assays of LHBs.

RESULTS

In the RCT group, there were 8 partial-thickness tears with 5 macroscopic LHB lesions, 12 full-thickness tears with 8 macroscopic LHB lesions, and 14 massive tears with 13 macroscopic LHB lesions. There were 6 LHB subluxations. However, the macroscopic grading and the symptom duration were not correlated with the severity of the histology. In patients with massive tears, no matter what the macroscopic appearance of the LHB, the proportion of end-stage (grade 4) histologic LHB tendinopathy significantly increased (85.7%, P < .05) compared with patients with other types of RCTs. There was a consistently high incidence of advanced LHB histology (grade 3 or higher) in each classification of RCTs (75.0%-100.0%). The 8 patients in the control group showed milder histopathology (grade 1 or 2). The apoptosis index significantly increased as the tendinopathy progressed (P < .05).

CONCLUSIONS

The macroscopic pathology of LHB may not fully reflect the severity of tendinopathy, and the coexisting size of RCTs plays a role in the severity of LHB tendinopathy.

Disorders of the proximal and distal aspects of the biceps muscle

PROXIMAL ASPECT OF BICEPS: Tenodesis of the long head of the biceps may offer improved cosmesis, improved strength, and diminished activity-related pain compared with tenotomy, although comparative studies have shown similar outcomes in some patient populations. DISTAL ASPECT OF BICEPS: Operative treatment of both partial and complete distal biceps ruptures results in better outcomes compared with nonoperative care, although the optimal technique and fixation are yet to be determined. Nonoperative management is an acceptable treatment for patients willing to accept some loss of forearm supination and elbow flexion strength as well as changes in endurance and cosmesis.

Arthroscopic percutaneous repair of anterosuperior rotator cuff tear including biceps long head: a 2-year follow-up

BACKGROUND

To report the results of an arthroscopic percutaneous repair technique for partial-thickness tears of the anterosuperior cuff combined with a biceps lesion.

METHODS

The inclusion criteria were evidence of the upper subscapularis tendon tear and an articular side partial-thickness tear of the supraspinatus tendon, degeneration of the biceps long head or degenerative superior labrum anterior-posterior, above lesions treated by arthroscopic percutaneous repair, and follow-up duration > 24 months after the operation. American Shoulder and Elbow Surgeons (ASES) score, constant score, the pain level on a visual analogue scale, ranges of motion and strength were assessed.

RESULTS

The mean (± standard deviation) age of the 20 enrolled patients was 56.0 ± 7.7 years. The forward flexion strength increased from 26.3 ± 6.7 Nm preoperatively to 38.9 ± 5.1 Nm at final follow-up. External and internal rotation strength was also significantly increased (14.2 ± 1.7 to 19.1 ± 3.03 Nm, 12.3 ± 3.2 to 18.1 ± 2.8 Nm, respectively). Significant improvement was observed in ASES and constant scores at 3 months, 1 year and the time of final follow-up when compared with preoperative scores (p < 0.001). The mean subjective shoulder value was 86% (range, 78% to 97%).

CONCLUSIONS

The implementation of complete rotator cuff repair with concomitant tenodesis of the biceps long head using arthroscopic percutaneous repair achieved full recovery of normal rotator cuff function, maximum therapeutic efficacy, and patient satisfaction.

Simultaneous rotator cuff repair and arthroscopic biceps tenodesis using lateral row anchor

Treatment of concomitant long head of the biceps pathology in the setting of rotator cuff repair is often required. When a tenodesis of the biceps is used, additional anchors and surgical dissection are typically required. This adds additional surgical time, morbidity of additional surgical dissection, and additional anchor load and cost. We describe a novel technique for arthroscopic biceps tenodesis that uses the anterior lateral row anchor of a double-row rotator cuff repair to simultaneously secure the biceps tenodesis and rotator cuff tear. This technique provides a simple, reproducible, cost-effective means of performing a simultaneous biceps tenodesis and double-row rotator cuff repair.
