The management of the long head of the biceps in rotator cuff repair: A comparative study of high vs. subpectoral tenodesis

Comparable and Improved Clinical Outcomes, Pain Relief, Return to Sport, and Low Popeye Deformity Rates in Inlay Versus Onlay Open Subpectoral Biceps Tenodesis: A Systematic Review

PURPOSE

To directly compare clinical outcomes, including failure rates, incidence of Popeye deformity, and return to sport (RTS)/activity between inlay and onlay fixation techniques specifically for open subpectoral biceps tenodesis.

METHODS

A systematic search of PubMed, EMBASE, and Cochrane Library databases was conducted for studies published between 2014 and 2024. Inclusion criteria consisted of Level I to IV studies in English, reporting clinical outcomes for open subpectoral biceps tenodesis with at least a 2-year follow-up. Data on patient-reported outcome measures, RTS, Popeye deformity, and failure rates were extracted. Risk of bias was assessed using the Methodological Index for Non-Randomized Studies criteria. Statistical analysis was performed to evaluate heterogeneity, and clinical outcomes between fixation techniques were compared using qualitative analysis and 95% confidence intervals.

RESULTS

Fourteen studies with a total of 498 patients (347 in the inlay group, 151 in the onlay group) were included. Postoperative American Shoulder and Elbow Surgeons scores ranged from 78.6 to 95.8, visual analog scale pain scores from 0.25 to 2.6, and Constant-Murley scores from 26.7 to 91.8, with no differences noted between inlay and onlay techniques across these measures on qualitative assessment. RTS rates were similarly comparable, ranging from 62% to 93% across all studies. The incidence of Popeye deformity was low in both groups, ranging from 0% to 7.7% for inlay fixation and from 0% to 6.7% for onlay fixation, with no qualitative differences observed. Heterogeneity in outcomes was attributed to variations in study design and patient populations.

CONCLUSIONS

Both inlay and onlay fixation for open subpectoral biceps tenodesis showed comparable clinical outcomes, similar pain relief, and low rates of Popeye deformity. RTS rates were consistently high across both techniques. The choice of fixation method did not significantly impact the overall results, suggesting that either technique can be used effectively based on surgeon and patient preferences.

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.

Modified arthroscopic intra-articular transtendinous looped biceps tenodesis leads to satisfactory functional outcomes and less frequent Popeye deformity compared to biceps tenotomy

PURPOSE

The present study aimed to propose a modified intra-articular transtendinous looped biceps tenodesis (mTLBT) using a suture anchor and to compare the functional outcomes and incidence of Popeye deformities between biceps tenotomy and mTLBT.

METHODS

Medical records of patients who underwent either tenotomy or mTLBT for the long head of the biceps tendon (LHBT) lesion between January 2016 and April 2021 were retrospectively reviewed. The inclusion criteria were patients aged 40-70 years with LHBT pathologies, such as superior labrum anterior to posterior (SLAP) lesions > type II, LHBT pulley system rupture with bicipital instability, and intra-articular LHBT tear. The exclusion criteria were full-thickness supraspinatus tears, frozen shoulder, shoulder fracture, and postoperative traumatic events that affected the operated shoulder. All patients were followed up for at least 1 year. Popeye deformity, bicipital cramping pain, visual analog scale (VAS) pain score, and functional outcome scores (University of California at Los Angeles [UCLA] and American Shoulder and Elbow Surgeons [ASES] scores) were recorded. Fisher's exact test and Chi-square test were used for categorical variables, whereas the Mann-Whitney U test was used for nonparametric variables.

RESULTS

The mTLBT and tenotomy groups included 15 and 40 patients, respectively. The incidence of Popeye deformity and biceps cramping pain in the tenotomy group (52.5% and 50%, respectively) was significantly higher than that in the mTLBT group (13.3% and 20%, respectively) (p = 0.009 and p = 0.045, respectively). The postoperative VAS, UCLA, and ASES scores were not significantly different between the two groups. One patient in the tenodesis group experienced metallic-anchor pullout.

CONCLUSION

mTLBT is an arthroscopic intra-articular top of the groove tenodesis that can be performed completely in the intra-articular space and is especially suitable for patients with an intact or partially torn rotator cuff. This technique is reliable for treating biceps pathologies as it results in similar functional outcome scores, lesser biceps cramping pain, and less frequent Popeye deformity compared to biceps tenotomy.

Onlay Versus Inlay Biceps Tenodesis for Long Head of Biceps Tendinopathy: A Systematic Review and Meta-analysis

INTRODUCTION

Proximal biceps tenodesis is a common surgical treatment of tendinosis of the long head of the biceps tendon. Two of the most common techniques incorporate onlay and inlay fixation methods, which can be done arthroscopically or open and in a variety of anatomic locations. The purpose of this meta-analysis was to compare the clinical outcomes between onlay versus inlay humeral fixation for biceps tenodesis for long head of the biceps tendon pathology.

METHODS

A literature search was conducted using PubMed, EMBASE, and Cochrane Library. Only studies reporting outcomes and complications after onlay and inlay biceps tenodeses were included.

RESULTS

Six studies with a total of 418 patients (252 onlay, 166 inlay) with a mean age of 56.84 years were included. Visual analog pain scale scores, Constant score, and American Shoulder and Elbow Surgeons shoulder score did not differ. "Popeye" deformity was found in 17 patients (7.80%) in the onlay group and in 15 patients (11.28%) in the inlay group (odds ratio, 0.28; P = 0.07). No difference in postoperative cramping or failure rates was found.

CONCLUSION

Both onlay and inlay biceps tenodeses result in improved clinical outcomes and are at low risk of Popeye deformities, with no statistically significant differences between either method. Additional studies are required to assess the clinical significance of these differences.

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.
