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

Higher complication rate is associated with suprapectoral biceps tenodesis as compared to subpectoral tenodesis: a systematic review and meta-analysis of comparative studies

INTRODUCTION

Biceps tenodesis techniques can be grouped into open or arthroscopic according to surgical approach, and into subpectoral or suprapectoral according to location of fixation. The purpose of this meta-analysis is to critically analyse the current evidence with regard to comparing two methods of biceps tenodesis, viz subpectoral vs supratenodesis.

METHODS

Primary electronic search was conducted on MEDLINE (PubMed), Embase, Scopus, and Cochrane Library databases for published literature from year of inception to August 2024. The current review included any prospective or retrospective English studies that evaluated the outcomes of suprapectoral versus subpectoral. Primary outcomes of interest were American shoulder and elbow society (ASES) score, constant score (CS), UCLA score, SST score, VAS, and complications. The secondary outcomes of interest was range of movements.

RESULTS

Thirteen studies were included in our quantitative analysis, comprising three RCTs and ten non-randomized comparative studies. ASES score was slightly higher in most of studies in favour of subpectoral tenodesis [95% CI (- 1.35, 0.10); I2 = 43%] (P > 0.05). We found no statistically significant difference between the two groups (P = 0.81), although the subpectoral tenodesis group had slightly higher mean CS 95% CI (- 0.95, 0.85), p = 0.81, I2 = 0%]. Our meta-analysis found a slightly higher SST in suprapectoral tenodesis group [95% CI (- 0.18, 0.49); I2 = 0%], while higher UCLA scores [P = 0.98; 95% CI (- 0.52, 0.50); I2 = 45%] in the subpectoral group (P > 0.05). Higher overall complication rate was noted with suprapectoral tenodesis group [OR 2.65; 95% CI (1.57, 4.45), I2 = 49%] (P = 0.0002).

CONCLUSION

Both the techniques of biceps tenodesis have shown comparable functional outcomes in most of the trials. On performing meta-analysis, suprapectoral tenodesis was associated with higher rate postoperative complications. Hence, it is advisable to choose subpectoral tenodesis, as and when possible.

Both Isolated Long Head of the Biceps Tenotomy and Tenodesis Are Effective for Symptomatic Rotator Cuff Repair Revision

Background: Symptomatic rotator cuff (RC) repair continues to be a complex issue. Leaving the long head of the biceps (LHB) in place might increase the risk of residual pain, even in the case of a healed RC. The purpose of this study was to assess the clinical outcomes of isolated LHB tenotomy and tenodesis as a revision procedure in symptomatic patients that had previously undergone an arthroscopic RC repair with no clinical or MRI evidence of RC retear. Methods: A retrospective analysis was conducted on patients with a persisting painful shoulder after an arthroscopic RC repair with no clinical or MRI signs of cuff retear, undergoing an isolated arthroscopic biceps tenotomy or tenodesis as a revision procedure. Functional outcomes were assessed preoperatively and at a minimum of 24 months of follow-up. Results: A total of 88 patients were included. The biceps tendon was managed with biceps tenodesis in 64 patients and tenotomy in 24 patients. VAS, Constant Score, SSV and active anterior elevation were all significantly improved after revision surgery. There was no significant difference between pre- and postoperative anterior passive elevation. No significant difference was shown between the tenodesis and tenotomy groups. Conclusions: The present study demonstrated that both isolated tenotomy and tenodesis are effective and safe in treating patients with a symptomatic shoulder after RC repair at a 2-year follow-up with a very low complication rate. Although tenodesis did not show any significant clinical benefit outcomes compared to tenotomy, it might be associated with a lower risk of Popeye deformity.

Clinical Outcome of an All Arthroscopic 'Whole Layer' Rotator Cuff Repair Technique with Simultaneous Biceps Tenodesis

OBJECTIVE

To retrospectively evaluate clinical outcomes, including function and pain, of patients after our all arthroscopic "whole layer" rotator cuff repair technique with simultaneous biceps tenodesis procedure; factors influencing results were also evaluated. Given the frequent association of rotator cuff tear with long head of biceps lesion and the need for effective combined treatment strategies, this study aims to evaluate the efficacy of our technique and compare it with established methods. We hypothesized that our technique would significantly improve function and reduce pain in patients with rotator cuff tears and biceps pathology.

METHODS

This is a retrospective study that included patients older than 20 years who underwent all arthroscopic "whole layer" rotator cuff repair technique with simultaneous biceps tenodesis procedures for concomitant rotator cuff tear and long head biceps pathology, from 2016 to 2020. Patients were evaluated preoperatively and at a minimum of 2 years of follow-up using the American Shoulder and Elbow Surgeons (ASES) and visual analogue scale (VAS) scores paired t-tests were used for analysis and statistical significance was set at p < 0.05(two-tailed). The satisfaction rate and complications were also evaluated.

RESULTS

After an average follow-up of 2.3 years, 118 patients demonstrated significant improvement in both the ASES score (from 36.13 to 95.01, p < 0.001) and VAS score (from 6.81 to 0.89, p < 0.001). Ninety-four percent of the patients reported satisfaction with the surgical outcome. No complications related to Popeye deformity, biceps cramping pain, or ipsilateral shoulder reoperation were observed. Factors such as age, sex, body mass index (BMI), smoking status, alcohol consumption, hypertension, and diabetes did not influence the results. Patients showed significant improvement in both the ASES and VAS scores (p < 0.001).

CONCLUSION

At a mean follow-up time of 2.3 years, the all arthroscopic "whole layer" rotator cuff repair technique with simultaneous biceps tenodesis is a therapeutic and efficient procedure. The procedure revealed a satisfactory functional outcome, reduced pain, and minimal complications and reoperations.

Return to Sports and Clinical Results After All-Arthroscopic Biceps Tenodesis Using a 2.7-mm Knotless PEEK Suture Anchor

Background

The long head of the biceps tendon (LHBT) is a well-known source of pain in the shoulder, especially in active patients.

Purpose

To evaluate the outcomes and return-to-sports rate after all-arthroscopic suprapectoral tenodesis of the LHBT using a small knotless anchor.

Study Design

Case series; Level of evidence, 4.

Methods

In this retrospective study, 27 patients-who underwent all-arthroscopic tenodesis of the LHBT using a 2.7-mm knotless polyether ether ketone anchor-were evaluated. Sports activities, the return-to-sports rate, and other sports-related parameters (eg, pain during sports, level of sports) were examined. Sports-related data, the Constant score with isometric force (at 90° of abduction in the scapular plane), the American Shoulder and Elbow Surgeons (ASES) score, the Simple Shoulder Test (SST) score, the visual analog scale (VAS) score for satisfaction, range of motion, and the presence of a Popeye deformity were assessed at a mean follow-up of 15.3 ± 8.7 months. The data were initially analyzed using descriptive statistics.

Results

The postoperative ASES, Constant, and SST scores were 81.61, 85.74 and 8.85, respectively. Of the 27 patients, 4 patients (14.8%) showed a Popeye deformity. Preoperatively, 25 patients (92.6%) participated regularly in some type of sports activity. All 25 patients (100.0%) were able to return to sports activities after surgery. 24 (96.0%) returned to the same level preoperatively, with 88.0% (22/25) within 6 months. Patient satisfaction with the outcome was high (VAS score: 2.15 ± 2.78). Neither bicipital groove pain nor cramping was reported. There were no signs of osteolytic bone around the anchor or a fracture of the humeral bone.

Conclusion

Our clinical results after using a 2.7-mm knotless anchor for LHBT tenodesis as well as the return-to-sports rate were satisfying. Using an anchor this size can lower the risk of cortical bone damage and therefore the risk of fractures of the humeral head while still enabling patients to perform at a high level.

Variations in subpectoral biceps tenodesis locations do not impact clinical outcomes

Background

Biceps tenodesis is a common treatment for pathologies involving the long head of the biceps brachii. Given variations in surgical approach, focus has been placed on the location of the tenodesis to maintain appropriate length-tension relationship. The purpose of this study is to assess for variations in the tunnel placement in subpectoral biceps tenodesis procedures and correlation of tunnel position with patient-reported outcomes.

Methods

This is a retrospective case series of outcomes as a function of tunnel location with open subpectoralis biceps tenodesis. The location of the biceps tenodesis tunnel was measured on postoperative Grashey radiographs. Correlation between the tenodesis tunnel and postoperative American Shoulder and Elbow Surgeons (ASES) score and Visual Analog Scale (VAS) was assessed.

Results

31 patients were included in the study with an average follow-up of 17 months. The overall tunnel position from the superior edge of the greater tuberosity ranged from 4.20 cm to 12.61 cm, with an average of 7.46 cm. Final ASES score and VAS were 84.5 and 1.2, respectively. There was only weak correlation between both ASES score and tunnel position (r = -0.12) and VAS and tunnel position (r = -0.23).

Discussion

Subpectoralis biceps tenodesis continues to be a viable treatment option for biceps and superior labral pathology. There remains no consensus on tenodesis location, and this study found no significant difference between tunnel location and patient-reported outcomes. Therefore, it is likely that a range of tenodesis locations exists in which favorable clinical results are achieved, explaining the numerous recommendations on tunnel placement.

Arthroscopic biceps tenodesis using press-fit bony plug: a case series study

PURPOSE

To assess the feasibility, operative time, clinical outcomes, possible complications, and failure rates of all-through arthroscopic biceps tenodesis using press-fit bony plug technique.

METHODS

This prospective case series study involved 30 skeletally mature patients with long head of biceps pathology (tendinitis after failure of conservative treatment, subluxation, dislocation, or tendon tears). All patients were followed up for 24 months at least.

RESULTS

Twenty-nine patients regained full shoulder and elbow range of motion; one case suffered from reflex sympathetic dystrophy. There was a significant improvement in the constant, ASES, and VAS scores when comparing the pre-operative and post-operative values. The average biceps strength was 96% compared to the opposite healthy side. No cases were complicated by neuro-vascular deficits or failure of the tenodesis.

CONCLUSION

Press-fit biceps tenodesis is safe and accessible with low economic demands. We recommend this technique to be used more often when addressing patients with long head of biceps pathologies.

Arthroscopic In Situ Biceps Tenodesis Using a Double Loop-and-Tack Knotless Suture Anchor

The long head biceps tendon is a common culprit of anterior shoulder pain and dysfunction that can be surgically treated with tenotomy or tenodesis. Many techniques exist for tenodesis. This article submits an arthroscopic technique using two loop-and-tack sutures and a knotless suture anchor to tenodese the long head biceps tendon in the proximal bicipital groove in situ. The advantage of this technique is that it maintains the biceps in its native position by performing tenodesis before tenotomy. Most other techniques attempt to restore native position of the biceps through approximation. The transverse humeral ligament is also released to decompress the bicipital groove. This technique can be used to treat isolated biceps pathology or combined with rotator cuff and labral procedures.

Depressive and Anxiety Disorders Increase Risk for Recurrent Anterior Shoulder Pain Following Arthroscopic Suprapectoral Biceps Tenodesis

Purpose

To evaluate factors associated with postoperative anterior shoulder pain following arthroscopic suprapectoral biceps tenodesis (ABT) and to determine the clinical impact of postoperative anterior shoulder pain.

Methods

A retrospective study of patients that underwent ABT between 2016 and 2020 was conducted. Groups were categorized by the presence (ASP+) or absence (ASP-) of postoperative anterior shoulder pain. Patient-reported outcomes (American Shoulder and Elbow score [ASES], visual analog scale [VAS] for pain, subjective shoulder value [SSV]), strength, range of motion, and complication rates were analyzed. Differences between continuous and categorical variables were tested with two-sample t-tests and chi-squared or Fisher's exact tests, respectively. Variables collected at different postoperative timepoints were analyzed using mixed models with post hoc comparisons when significant interactions were detected.

Results

A total of 461 (47 ASP+, 414 ASP-) patients were included. A statistically significant lower mean age was observed in the ASP+ group (P < .001). A statistically significant higher prevalence of major depressive disorder (MDD) (P = .03) or any anxiety disorder (P = .002) was observed in the ASP+ group. Prescription medication with psychotropic medications (P = .01) was significantly more prevalent in the ASP+ group. No significant differences were observed in the proportion of individuals reaching the minimal clinical important difference (MCID) for ASES, VAS, or SSV between groups.

Conclusions

A pre-existing diagnosis of major depressive disorder or any anxiety disorder, as well as the use of psychotropic medications was associated with postoperative anterior shoulder pain following ABT. Other factors associated with anterior shoulder pain included younger age, participation in physical therapy before surgery, and lower rate of concomitant rotator cuff repair or subacromial decompression. Although the proportion of individuals reaching MCID did not differ between groups, the presence of anterior shoulder pain after ABT resulted in prolonged recovery, inferior PROs, and a higher incidence of repeat surgical procedures. The decision to perform ABT in patients diagnosed with MDD or anxiety should be carefully considered, given the correlation to postoperative anterior shoulder pain and inferior outcomes.

A shallow morphology of the intertubercular groove is associated with medial and bilateral but not lateral pulley lesions

PURPOSE

To investigate the influence of intertubercular groove (IG) morphology on the development of different types of biceps reflection pulley (BRP) injuries.

METHODS

A consecutive cohort of 221 patients with ventral shoulder pain and a preoperative diagnosis suspecting BRP injury, who underwent arthroscopy, was retrospectively reviewed. The presence or absence as well as type of pulley injury (medial, lateral or bilateral) was confirmed arthroscopically. The intertubercular groove was evaluated on MRIs after triplanar reconstruction of the axial plane. IG depth, width, medial wall angle (MWA), lateral wall angle (LWA) and total opening angle (TOA) were measured. IG depth and width were expressed in relation to the humeral head diameter. Measurements were performed by two clinicians independently and averaged.

RESULTS

Of 166 included patients 43 had bilateral, 65 medial and 38 lateral BRP lesions. 20 patients had intact BRPs and represented the control group. The intra-class correlation coefficient of measurements was 0.843-0.955. Patients with a medial or bilateral BRP injury had a flatter MWA (38.8° or 40.0° vs. 47.9°, p < 0.001), wider TOA (96.1° or 96.6° vs. 82.6°, p < 0.001), greater width (12.5 or 12.3 vs. 10.8 mm, p = 0.013) and shallower depth (5.5 or 5.4 vs. 6.2 mm, p < 0.001) than the control group. Conversely, the IG morphology of those with lateral BRP injuries did not differ significantly from the control group. The odds ratio for a medial or bilateral BRP injury when the TOA exceeded 95° was 6.8 (95% confidence interval 3.04-15.2).

CONCLUSION

A dysplastic type of IG morphology with a wide TOA, flat MWA, decreased depth and increased width is associated with the presence of medial and bilateral BRP injuries. A TOA of > 95° increases the likelihood of a medial or bilateral BRP injury 6.8-fold. Lateral BRP injuries are not associated with dysplastic IG morphology. Concomitant LHBT surgery may, therefore, not always be necessary during isolated supraspinatus tendon repair.

Clinical effectiveness of tenotomy versus tenodesis for long head of biceps pathology: a systematic review and meta-analysis

OBJECTIVES

The comparative clinical effectiveness of common surgical techniques to address long head of biceps (LHB) pathology is unclear. We synthesised the evidence to compare the clinical effectiveness of tenotomy versus tenodesis.

DESIGN

A systematic review and meta-analysis using the Grading of Recommendations Assessment, Development and Evaluation approach.

DATA SOURCES

EMBASE, Medline, PsycINFO and the Cochrane Library of randomised controlled trials were searched through 31 October 2021.

ELIGIBILITY CRITERIA

We included randomised controlled trials, reporting patient reported outcome measures, comparing LHB tenotomy with tenodesis for LHB pathology, with or without concomitant rotator cuff pathology. Studies including patients treated for superior labral anterior-posterior tears were excluded. No language limits were employed. All publications from database inception to 31 October 2021 were included.

DATA EXTRACTION AND SYNTHESIS

Screening was performed by two authors independently. A third author reviewed the article, where consensus for inclusion was required. Data were extracted by two authors. Data were synthesised using RevMan. Inverse variance statistics and a random effects model were used.

RESULTS

860 patients from 11 RCTs (426 tenotomy vs 434 tenodesis) were included. Pooled analysis of patient-reported functional outcome measures data demonstrated comparable outcomes (n=10 studies; 403 tenotomy vs 416 tenodesis; standardised mean difference (SMD): 0.14, 95% CI -0.04 to 0.32, p=0.13). There was no significant difference for pain (Visual Analogue Scale) (n=8 studies; 345 tenotomy vs 350 tenodesis; MD: -0.11, 95% CI -0.28 to 0.06, p=0.21). Tenodesis resulted in a lower rate of Popeye deformity (n=10 studies; 401 tenotomy vs 410 tenodesis; OR: 0.29, 95% CI 0.19 to 0.45, p<0.00001). Tenotomy demonstrated shorter operative time (n=4 studies; 204 tenotomy vs 201 tenodesis; MD 15.2, 95% CI 1.06 to 29.36, p<0.00001).

CONCLUSIONS

Aside from a lower rate of cosmetic deformity, tenodesis yielded no significant clinical benefit to tenotomy for addressing LHB pathology.

The high resistance loop (H-loop) technique used for all-inside arthroscopic knotless suprapectoral biceps tenodesis: A case series

Introduction

Suprapectoral tenodesis is a common technique for the treatment of long head biceps tendon lesions. However, so far, there is no gold standard treatment in all-inside arthroscopy. The purpose of the present study was to introduce and evaluate the functional outcomes of an innovative, all-inside arthroscopic high resistance loop (H-loop, high resistance to tissue cutout and 360° grasping of the tendon) technique for long head of biceps (LHB) tenodesis.

Method

From September 2020 to March 2022, a series of cases of 32 consecutive patients (28 rotator cuff tear with LHBT pathology and 4 superior labrum anterior-posterior (SLAP) tears which including 2 type II and 2 type IV) who received LHB tenodesis using all-inside arthroscopic high resistance loop technique were included in this study. The American Shoulder and Elbow Surgeon Score (ASES), Visual Analog Scale (VAS), Simple Shoulder Test Score (SST), Constant–Murley scores, and University of California at Los Angeles Scoring System (UCLA) were used to evaluate the clinical outcomes of patients in preoperative and final follow-up. Meanwhile, postoperative complications were also observed.

Result

32 patients (14 women and 18 men, average age was 55.7 years) underwent all-inside arthroscopic knotless suprapectoral biceps tenodesis using the H-Loop stitch technique. The mean time of follow-up was 16.2 ± 2.6 months. The ASES, VAS, Constant–Murley, SST, and UCLA scores improved from 51.5 ± 15.8, 5.5 ± 1.6, 57.8 ± 14.7, 5.0 ± 2.8, and 16.1 ± 3.8 preoperatively, to 89.1 ± 7.5, 1.0 ± 0.8, 87.3 ± 5.5, 10.4 ± 1.5, and 31.3 ± 2.6 in the last follow-up, respectively (p < 0.001). During the follow-up, no patients in this study experienced postoperative complications such as infection of the wound, injury of nerves, and hardware failure; no patients required revision after their operation. In addition, none of the patients had cramping or a “Popeye” deformity during follow-up.

Conclusion

This article presents an innovative, all-arthroscopic H-loop technique for LHB tenodesis. This technique for LHB tenodesis showed favorable functional and cosmetic outcomes, as well as high satisfaction rates. Due to its simplicity of operation and satisfactory preliminary clinical outcomes, H-loop technique is perhaps another option to choose in all-inside arthroscopic LHB tenodesis.

Evaluation of Rotator Cuff Repair With and Without Concomitant Biceps Intervention: A Retrospective Review of Patient Outcomes

BACKGROUND

Biceps tendon pathology is common in patients with rotator cuff tears. Leaving biceps pathology untreated in rotator cuff repairs (RCRs) may lead to suboptimal outcomes.

PURPOSE/HYPOTHESIS

The purpose was to compare clinical outcomes between patients who underwent isolated RCR versus patients who underwent RCR with concomitant biceps treatment. It was hypothesized that there would be no difference in clinical outcomes between groups.

STUDY DESIGN

Cohort study; Level of evidence, 3.

METHODS

A total of 244 patients who underwent RCR in 2016 were included. Patient characteristics, presence of concomitant biceps pathology, pre- and postoperative American Shoulder and Elbow Surgeons (ASES) scores, rotator cuff failure, revision surgery, and complications were recorded.

RESULTS

There were no significant differences between patients who underwent isolated RCR (n = 143) and those who underwent RCR with biceps treatment (n = 101) at 2 years postoperatively in ASES scores (RCR, 81.5; RCR+biceps treatment, 79.5; P = .532), cuff failure rate (5.6% vs 4.0%; P = .760), revision RCR rate (3.5% vs 2.0%; P = .703), or complication rate (11.9% vs 5.0%; P = .102). Furthermore, when comparing concomitant biceps tenotomy (n = 30) versus concomitant biceps tenodesis (n = 71), there were no differences in ASES scores (P = .149), cuff failure rate (P > .999), revision RCR rate (P > .999), or complication rate (P > .999) postoperatively. Finally, when comparing arthroscopic biceps tenodesis (n = 50) versus subpectoral biceps tenodesis (n = 21), there were no differences in ASES scores (P > .592), cuff failure rate (P > .999), revision RCR rate (P = .507), or complication rate (P > .999) 2 years postoperatively.

CONCLUSION

Addressing biceps pathology when performing RCR resulted in similar rates of cuff failure, revision RCR, and complications, as well as a similar improvement in patient-reported outcomes when compared with isolated RCR at 2 years postoperatively. Furthermore, when comparing tenotomy versus tenodesis and arthroscopic versus subpectoral tenodesis, comparable outcomes with regard to rate of rotator cuff repair failure, revision RCR, complications, and patient-reported outcomes were found.

Critical shoulder angle (CSA): age and gender distribution in the general population

Objective

Anatomical parameters and pathologies that can affect the critical shoulder angle (CSA) are subjects of discussion. To date, we do not know if the CSA value changes in the different decades of life in a population characterized by the same ethnicity, nor if there are differences related to gender or side. This study hypothesizes that age and gender may affect the CSA.

Methods

Patients older than 15 years old affected by a shoulder trauma and who were discharged with a diagnosis of shoulder contusion were enrolled. A true AP view of the shoulder was obtained as well as data regarding age and gender of all participants. The CSA was measured by three authors, and interoperator reliability was assessed. Eight subcategories, according to decades of life, were considered. Finally, the studied population was divided into three subcategories according to CSA values (< 30°; 30–35°; ≥ 35°).

Results

The initial sample comprised 3587 shoulder X-rays. The interobserver reproducibility was high, with an intraclass correlation coefficient of 0.865 (95% CI 0.793–0.915).

Two thousand eight hundred seventy-three radiograms were excluded. The studied group comprised 714 patients [431 females, 283 males; mean age (SD): 47.2 (20.9) years, range: 11–93 years]. The mean CSA was 33.6° (range: 24–50°; SD: 3.9°). The mean CSA values in females and males were 33.7°and 33.5°, respectively. The mean CSA values of the right and left shoulders were 33.3° and 33.9°, respectively (p > 0.05). Linear regression analysis showed a CSA increase by 0.04° every year. The mean CSA in subjects aged between 15 and 19 years was significantly lower than all the other groups, except for patients older than 80 years.

No significant differences were found between CSA subcategories, gender, or side.

Conclusions

In the general population, the mean CSA value was 33.6°. No significant differences were found regarding the mean CSA value according to gender or side. A significant positive linear correlation between CSA and age was detected. In each decade of life, the CSA value, which is genetically determined, shows a large variability.

Shoulder Long Head Biceps Tendon Pathology Is Associated With Increasing Rotator Cuff Tear Size

Purpose

To evaluate the association between rotator cuff tear (RCT) size and long head biceps tendon (LHBT) pathology.

Methods

We retrospectively enrolled 202 consecutive patients (114 women and 88 men with mean age at surgery of 62.14 years [SD, 7.73]) who underwent arthroscopic rotator cuff repair for different sized full-thickness RCTs. LHBT pathology was evaluated considering the presence of inflammation, section alteration, loss of integrity, dislocation, dynamic instability, and absence. The site of LHBT pathology was evaluated considering 3 portions: (1) the insertional element; (2) the free intra-articular portion; (3) the part that enters the intertubercular groove. Statistics were evluated.

Results

The LHBT was absent in 22 cases (10.9%): 2, 4, 15, and 1 patients with small, large, massive, and subscapularis RCTs, respectively. A significant correlation was found between the prevalence of LHBT absence and massive RCTs (P < .001). In 53 patients (26%), there was a healthy LHBT; a healthy LHBT was present in 47%, 20% and 8% of small, large and massive RCTs, respectively. A significant correlation between LHBT inflammation, section alteration, loss of integrity, and RCT severity was found (P < .001, P < .001, and ). The insertional portion was the most involved (57% of cases); RCT severity was significantly associated with the number of involved portions (P < .001).

Conclusions

Shoulder LHBT pathology is associated with increasing rotator cuff tear size.

Clinical Relevance

Surgeons should be aware that biceps pathology is particularly prevalent in patients with larger RTCs.

Expression of Substance P and Nerve Growth Factor in Degenerative Long Head of Biceps Tendon in Patients with Painful Rotator Cuff Tear

Purpose

Degenerative long head of biceps tendon (LHBT) has been recognized as a notable pain source in patients with rotator cuff tear (RCT). Tenotomy or tenodesis of LHBT is frequently indicated together with arthroscopic rotator cuff repair (ARCR) aiming for complete pain relief; however, it has not been fully investigated whether resected LHBT is really a source of pain. The purpose of this study was to investigate expression levels of pain-associated mediators in LHBT and its association with preoperative pain profiles.

Methods

Twenty-seven RCT patients who underwent ARCR with LHBT resection were included. Each LHBT was resected due to its abnormal arthroscopic findings including tenosynovitis, hypertrophy, and partial tear. Worst macroscopic lesion of the LHBT was obtained, and expression levels of substance P (SP) and nerve growth factor (NGF) were evaluated using enzyme-linked immunosorbent assay (ELISA). Ten healthy knee flexor tendons were analyzed as non-degenerative samples. Preoperatively, subjective shoulder pain VAS and pain duration were investigated. Conventional LHBT pain provocation tests (Speed, Yergason, O’Brien) were performed. Pressure pain threshold (PPT) of bilateral LHBT on the groove was recorded.

Results

Levels of SP and NGF expression were significantly higher compared with non-degenerative tendons (P<0.01). Shoulder pain VAS and pain duration were not directly associated with SP and NGF expression level. Patients with positive O’Brien test expressed greater SP than negative patients (P=0.001). Significant negative correlation between the PPT ratio (ipsilateral/contralateral) and SP expression level was observed (r=−0.453, P=0.034).

Conclusion

Greater expression of SP and NGF in degenerative LHBT supported our hypothesis that it would be a pain source in RCT patients. SP was likely to be expressed highly in patients with localized pressure pain hypersensitivity and positive O’Brien test (ie, altered mechanistic pain profile of LHBT), which may help when considering simultaneous LHBT resection during ARCR.

Efficacy of management of associated dysfunctions on rotator cuff and long head of the biceps: systematic review

Background

The important functional role the rotator cuff (RC) and biceps play in the shoulder, the close anatomical relationship between them and the high incidence of injuries require an appropriate multidisciplinary therapeutic approach after a rigorous assessment. The objective is to identify and analyze surgical interventions, whether or not followed by a postsurgical one, of associated dysfunctions on the RC and long head of the biceps (LHB) and their effectiveness in improving shoulder functionality.

Methods

A systematic review based on PRISMA protocol was conducted using PubMed, Web of Science, PEDro, Scopus, CINAHL, and Dialnet until 22 April 2021. The main inclusion criteria were as follows: randomized clinical trials including subjects diagnosed with RC and LHB lesions who had surgical and/not post-surgical treatments. The methodological quality of trials was evaluated by the PEDro scale. Data were shown in 3 pre-established tables: (1)sample data, diagnostic methods, dysfunctions and injury frequency, interventions, outcome measures and results; (2)significance and effectiveness of interventions; and (3)comparison of the effectiveness of interventions.

Results

Eleven studies were selected. The methodological quality of ten of them was assessed as good and one excellent (PEDro scale). All articles had surgical treatments and ten had postoperative management. All trials used arthroscopy and two open surgery too. Single-row, double-row and transosseous repair were used for RC lesions, while SLAP repair, tenotomy, and tenodesis were applied to LHB injuries. Measured parameters were functionality, pain, Popeye’s sign, strength, range of motion, satisfaction degree, biceps cramping, and quality of life. All approaches in general, surgical plus postsurgical, were always effective to the parameters measured in each study. Seven trials compared tenotomy and tenodesis: four of them obtained statistically significant differences in favor of tenodesis in Popeye’s sign, cramping, satisfaction degree, and/or forearm supination strength; and one, in favor of tenotomy in cramping. All studies measured functionality using functional assessment scales. The most widely used was the Constant Score.

Conclusions

Surgical plus post-surgical interventions in associated dysfunctions on RC and LHB were effective. Tenodesis obtained better results than tenotomy in Popeye’s sign, satisfaction, and forearm supination strength. However, there was no difference regarding biceps cramping.

Cost comparison of arthroscopic rotator cuff repair with arthroscopic vs. open biceps tenodesis

PURPOSE

To use a nationwide database to determine differences in cost between patients who underwent arthroscopic rotator cuff tear with open vs. arthroscopic biceps tenodesis (BT).

METHODS

The 2014 State Ambulatory Surgical and Services Databases from 6 US states was utilized. All cases with CPT codes 29827 (arthroscopic rotator cuff repair [RCR]) and either 23430 (tenodesis of long tendon of biceps) or 29828 (arthroscopic BT) were selected. Cases that included both 23430 and 29828 were excluded, as were those missing demographic data. Generalized linear models were used to model costs based on the surgical and patient variables that were significant in the initial bivariate analysis (P < .05).

RESULTS

A total of 3635 RCR and BT cases were identified. There were 2847 (78.3%) with arthroscopic BT and 788 (21.7%) with open BT. Patients undergoing arthroscopic BT were 3.1 years older than patients undergoing open BT (P < .001). For arthroscopic BT, 39.2% of the cases were women compared with 22.6% of the open cases (P < .001). For operative variables, arthroscopic BT required 9 fewer minutes in the OR than open cases (P = .002). Concomitant distal clavicle resection was performed in 35.5% of arthroscopic BT cases compared with 29.8% of open cases (P = .004). While controlling for other significant factors, open BT was associated with $5542 lower costs than arthroscopic BT in the setting of RCR (P < .001). In either case, concomitant subacromial decompression added $10,669 (P < .001), and distal clavicle resection added $3210 (P < .001). High-volume surgical facilities were associated with $4107 lower costs (P < .001).

CONCLUSIONS

In a large series of patients undergoing arthroscopic RCR with open vs. arthroscopic BT, open BT was associated with $5542 lower costs than arthroscopic. Given that both techniques have been shown to be similarly effective in long-term follow-up, surgeons should be aware of opportunities for cost saving, particularly with the advent of bundled surgical reimbursements.

Biceps tenotomy versus tenodesis for lesions of the long head of the biceps tendon: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Biceps tenotomy and biceps tenodesis are 2 most common surgical procedures for long head of the biceps tendon (LHBT) pathology, but debate still exists regarding the choice of treatment. This meta-analysis was conducted to compare clinical results between tenotomy and tenodesis for the treatment of lesions of LHBT. It was hypothesized that there is no difference in outcomes of tenotomy and tenodesis for lesions of LHBT.

METHODS

A comprehensive search of literature published between 1980 and April 2020 was performed using MEDLINE, EMBASE, Web of Science, and the Cochrane Library databases. Randomized controlled trials (RCTs) comparing tenotomy and tenodesis for LHBT lesions were included. The primary outcomes were Constant score and Popeye deformity. The secondary outcomes included the American Shoulder and Elbow Surgeons (ASES) score, visual analog scale (VAS) for pain, muscle strength, cramping pain, and operative time. For primary outcomes, trial sequential analysis (TSA) was conducted to reduce the risk of random errors and the GRADE (grading of recommendations, assessment, development, and evaluations) approach was used to assess the quality of the body of evidence.

RESULTS

A total of 9 RCTs were included. In pooled analysis, statistical significance was observed in the Constant score (mean difference [MD], 1.59; 95% confidence interval [CI] 0.04-3.14; P = .04), Popeye deformity (risk ratio [RR], 0.33; 95% CI, 0.22-0.49; P < .00001) and operative time (MD, 9.94; 95% CI 8.39-11.50; P < .00001). However, there were no significant differences between the tenodesis and tenotomy in ASES score (P = .71), VAS for pain (P = .79), cumulative elbow flexion strength (P = .85), cumulative elbow supination strength (P = .23), and cramping pain (P = .61) TSA revealed that the results for Constant score was inconclusive.

CONCLUSION

For the treatment of LHBT lesions, with the exception of constant score, there was no significant benefit of tenodesis over tenotomy. Although tenotomy is affected by a higher risk of Popeye sign, it is more timesaving.

Clinical Outcomes of an All-Arthroscopic Biceps Tenodesis Using the Anterolateral Anchor During Concomitant Double-Row Rotator Cuff Repair

Background:

Pathology of the long head of the biceps tendon frequently occurs concomitantly with rotator cuff tears, necessitating a surgical treatment, often in the form of a tenodesis procedure. Many techniques for a tenodesis exist; however, they often require additional implants or a separate incision.

Purpose:

To report an average of 2-year outcomes of an all-arthroscopic biceps tenodesis employing the stay sutures from the anterolateral anchor during concomitant double-row rotator cuff repair (RCR).

Study Design:

Case series; Level of evidence, 4.

Methods:

Data were prospectively collected and retrospectively reviewed for all patients who underwent an all-arthroscopic biceps tenodesis during concomitant double-row RCR by the senior author between January 2014 and May 2018. Patients were included if they underwent this procedure and had baseline preoperative patient-reported outcomes (PROs) with a minimum of 1 year of postoperative PROs for the American Shoulder and Elbow Surgeons (ASES) score and visual analog scale (VAS) for pain score. Additionally, patient data, surgical history, postoperative complications, and satisfaction were reported.

Results:

Fifteen patients were eligible for the study. There were 12 (80%) men and 3 (20%) women with a mean age of 50.0 years (range, 35-64 years). The mean follow-up time was 25.2 months (range, 13-63 months). Six of 15 (40%) patients also had an arthroscopic subscapularis repair performed. ASES shoulder scores improved from 37.1 preoperatively to 94.1 postoperatively (P < .001), and VAS scores improved from 6.4 preoperatively to 0.5 postoperatively (P < .001). One patient who underwent concomitant subscapularis repair reported continued anterior groove pain. No patients experienced biceps cramping, developed a deformity, or required a repeat operation at the final follow-up. Overall, 93.3% of the patients reported being highly satisfied with their surgery.

Conclusion:

This study presents the clinical results of an all-arthroscopic technique for concomitant double-row RCR and biceps tenodesis, which resulted in high rates of patient satisfaction and significant improvement in reported shoulder outcome and pain scores. Additionally, this technique offers the potential benefits of avoiding a secondary incision, which may decrease surgical morbidity while also decreasing cost by eliminating the need for an extra, tenodesis-specific implant.

A Historical Analysis of Randomized Controlled Trials in Rotator Cuff Tears

Background and objectives: Our research aimed to evaluate the quality of reporting of randomized controlled trials (RCTs) linked to rotator cuff (RC) tears. The present study analyzed factors connected to the quality of the RCTs and trends in the quality of reporting through time. Materials and Methods: The online databases used to search all RCTs on the topic of RC surgery completed until March 2020 were PubMed and Ovid (MEDLINE). The quality of reporting was evaluated using the modified Coleman methodology score (MCMS) and the consolidated standards of reporting trials (CONSORT). Results: The online search found 957 articles. Finally, 183 studies were included in the quantitative synthesis. A total of 97 (53%) of 183 studies had a level of evidence I and 86 (47%) of 183 studies had a level of evidence II, according to the Oxford Center of Evidence Based Medicine (EBM). A statistically significant difference in MCMS between articles written before 2010 and articles written after 2010 was found. Articles written after 2010 had, on average, the highest Coleman score. The average number of CONSORT checklist items for each article across all analyzed RCTs was 21.67. The 37 studies completed up to 2010 averaged a number of checklist items of 19.97 and the studies completed between 2011 and 2019 averaged a number of checklist items of 22.10. A statistically significant difference in the number of checklist items between articles written before 2010 and articles written after 2010 was found. Articles written after 2010 had on average more checklist items. However, low correlation (0.26) between the number of checklist items for each article and the respective Coleman score was found. On the other hand, articles with the CONSORT diagram had a significantly high Coleman score. Conclusions: An improvement in the quantity and quality of RCTs relating to RC surgery over the analyzed period was found.

Increased Risk of Humeral Fracture With Open Versus Arthroscopic Tenodesis of the Long Head of the Biceps Brachii

Purpose

To determine the risk of postoperative humeral fracture following tenotomy, open tenodesis and arthroscopic tenodesis of the long head of the biceps brachii.

Methods

A retrospective review of deidentified patient data from the Medicare Standard Analytic File using the PearlDiver software was conducted to identify procedures performed between 2005 and 2014. Groups were matched by age, gender, region, and medical comorbidities.

Results

We evaluated 157,163 patients who had undergone arthroscopic or open tenodesis or tenotomy of the long head of the biceps brachii over a 10-year period (2005-2014), and we identified 2,196 postoperative humeral fractures (1.4%). Matched subgroup analysis consisting of 44,292 patients demonstrated a statistically significant increase in humeral fracture risk in open (280; 1.26%) compared to arthroscopic tenodesis (232; 1.04%) with a P value of 0.03 and an odds ratio of 1.21. The majority of fractures were sustained by patients 65-74 years of age.

Conclusion

In this study, an increased risk of postoperative humeral fracture was associated with open tenodesis of the LHB.

Level of Evidence

III, Retrospective Comparative Trial.

Staged arthroscopic procedure for treating simultaneous shoulder and elbow synovial chondromatosis: A case report and literature review

It is extremely rare for ipsilateral shoulder and elbow synovial chondromatosis to occur simultaneously. We report a very rare case of simultaneous shoulder and elbow synovial chondromatosis in a 53-year-old woman who was treated through staged surgeries. Shoulder arthroscopic synovectomy, debridement, biceps tenodesis, and subacromial decompression were conducted first, followed by elbow arthroscopy 2 months later. Post surgery, there was no recurrence either clinically or radiologically at 2 years follow-up. Despite some loss of the range of motion of the shoulder and muscle strength, the elbow functions recovered fully, and the patient was extremely satisfied with the clinical outcome. We recommend a staged arthroscopic procedure consisting of a thorough synovectomy and joint debridement for this condition.

Suprapectoral versus subpectoral tenodesis for Long Head Biceps Brachii tendinopathy: A systematic review and meta-analysis

BACKGROUND

Suprapectoral long head biceps (LHB) tenodesis and subpectoral LHB tenodesis are both commonly performed surgical procedures. Due to the more proximal position of the suprapectoral tenodesis site this technique may be accompanied with more postoperative pain in the bicipital groove and cramping pain in the biceps muscle. We hypothesized that subpectoral tenodesis is associated with a better clinical outcome than suprapectoral tenodesis.

METHODS

A literature search was conducted in PubMed and Embase from January 2000 to July 2019 with the terms "biceps" and "tenodesis". Only comparing studies reporting on American Shoulder Elbow Score (ASES), VAS for anterior shoulder pain, Constant Murley Score (CMS), pain in the bicipital groove and Popeye deformity following suprapectoral and subpectoral tenodesis were included. Quality assessment of included articles was performed using the Coleman score.

RESULTS

Seven comparative studies with 409 patients reporting the results of LHB suprapectoral and subpectoral tenodesis were included. A significant, but clinically irrelevant difference in ASES (mean difference 2.15) p=0.01 was observed. No significant difference in CMS (mean difference 0.09), VAS for anterior shoulder pain (mean difference 0.01), Popeye deformity (odds ratio 3.19) and persistent bicipital pain (odds ratio 2.66). The Coleman score ranged between 53 and 87.

CONCLUSION

Based on this meta-analysis we found a significantly, though not clinically relevant difference in ASES in favour of subpectoral LHB tenodesis when compared with suprapectoral LHB tenodesis. Comparable results were found with regard to outcome scores, pain in the bicipital groove and avoiding a Popeye deformity.

All-Arthroscopic Biceps Tenodesis Using the Anterolateral Anchor During Concomitant Double-Row Rotator Cuff Repair

Arthroscopic biceps tenodesis is a commonly performed procedure; however, there is a paucity of literature regarding concomitant biceps tenodesis and double-row rotator cuff repair. In this Technical Note, we describe an all-arthroscopic biceps tenodesis using the stay sutures from the anterolateral anchor in the setting of a double-row rotator cuff repair. The anterolateral anchor is placed adjacent to the bicipital groove to accommodate the tenodesis. Two sutures loaded into the anterolateral anchor are passed through the long head of the biceps tendon in a cinch configuration without the need to externalize the tendon. The sutures are tied arthroscopically, thereby securing the tendon to the anterolateral row anchor and completing the tenodesis.
