Arthroscopic soft tissue tenodesis versus bony fixation anchor tenodesis of the long head of the biceps tendon

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.

Radiological changes in anterior arm muscles after biceps long head tenotomy

BackgroundAlthough a decrease in pain may be observed after tenotomy, conditions such as muscle cramp, limited elbow flexion, cosmetic deformity (Popeye sign), decreased elbow flexion-supination strength, and persistent pain are also seen, and the exact cause is not fully known.PurposeTo evaluate the changes in the short head of the biceps brachii (SHB) tendon thickness and coracobrachialis muscle after tenotomy.Material and MethodsIn this original article, magnetic resonance imaging (MRI) was performed preoperatively and 6 months postoperatively on 77 patients who underwent biceps brachii long head tenotomy during shoulder arthroscopy and who met the inclusion criteria. Changes in the thickness of the SHB and the coracobrachialis muscle were evaluated. The location where the long head of the biceps brachii (LHB) terminated after tenotomy was also investigated.ResultsIn the 6th postoperative month, we observed a significant increase in both the thickness of the SHB footprint and 2 cm distal to the tendon's origin. In addition, the LHB, which underwent tenotomy, was distracted on average 24.2 mm distally. However, no changes were observed in the thickness of the coracobrachialis muscle during the same period.ConclusionIn this study, we demonstrated prospectively increased thickness of the SHB tendon and no increase in thickness in the coracobrachialis muscle on postoperative MRI.

Editorial Commentary: Outcomes of Shoulder Biceps Tenotomy Versus Tenodesis Are Difficult to Determine From Nonrandomized Studies Due to Selection Bias: Tenodesis Is More Commonly Performed on Younger Males

The long head of the biceps tendon is a common source of anterior shoulder pain, frequently addressed during rotator cuff repairs. Surgical management typically involves either tenotomy or tenodesis, each offering distinct advantages and disadvantages. Tenotomy, a straightforward procedure with a short rehabilitation period, is well suited for low-demand patients but carries a higher risk of Popeye deformity and cramping pain. In contrast, tenodesis, which reattaches the long head of the biceps tendon, minimizes these risks and is preferred for younger, active patients. Randomized controlled trials have shown equivalent functional outcomes for both techniques, with tenotomy associated with a higher risk of cosmetic deformity. The choice of a specific technique often reflects patient age, activity demands, and cosmetic concerns. Surgeons are more likely to select tenodesis for younger, male patients. Thus, nonrandomized studies introduce confounding variables and selection bias that can obscure clear recommendations based on the literature.

Biomechanical comparisons of all--suture suspensory button vs. interference screw for inlay subpectoral bicep tenodesis

BACKGROUND

All-suture buttons (ASBs) and interference screw (IS) are commonly utilized in the inlay subpectoral biceps tendon tenodesis. However, the biomechanical characteristics of these two methods have not been compared directly. The aim of present study was to compare the biomechanical properties of ASB vs. IS for inlay subpectoral biceps tendon tenodesis in a human cadaveric model.

METHODS

Sixteen fresh-frozen human cadaveric shoulders were randomly divided into two experimental inlay biceps tenodesis groups: ASB or IS. After tenodesis, every specimen was preloaded at 5 N for 2 minutes, followed with a cyclic loading test from 5 to 70 N for 500 load cycles. Then the load-to-failure test was performed. Afterward, the humerus was placed in a cylinder tube and secured with anchoring cement. Lastly, a two-point bending test was performed to determine the strength of the humerus. Destructive axial force was applied, and the failure strength and displacement were recorded.

RESULTS

No difference in stiffness was observed between the two groups (ASB = 27.4 ± 3.5 N/mm vs. IS = 29.7 ± 3.0 N/mm; P = .270). Cyclic displacement was significantly greater in the ASB group (6.8 ± 2.6 mm) than the IS group (3.8 ± 1.1 mm; P = .021). In terms of failure load, there were no statistical differences among the two groups (P = .234). The ASB group was able to withstand significantly greater displacement (11.9 ± 1.6 mm) before failure than the IS group (7.8 ± 1.5 mm; P = .001). During the humeral bending test, the ASB group exhibited significantly greater maximal load (2354.8 ± 285.1 N vs. 2086.4 ± 296.1 N; P = .046) and larger displacement (17.8 ± 2.8 mm vs. 14.1 ± 2.8 mm; P = .027) before fracture.

CONCLUSIONS

In inlay subpectoral bicep tenodesis, ASB fixation appears to offer comparable stiffness and failure load to that of IS fixation. Additionally, the ASB group exhibited greater resistance to load and displacement before humeral fracture. However, the ASB group did demonstrate increased cyclic displacement compared to IS group.

Outcomes of Subpectoral Tenodesis in the Treatment of Proximal Biceps Pathologies

Introduction The aim of this article is to evaluate the clinical and functional outcomes of subpectoral tenodesis of the long head of the biceps (LHB) in the treatment of proximal biceps pathologies. Methods A retrospective, cross-sectional study was conducted through the analysis of medical records from 24 patients and 26 shoulders who underwent the subpectoral tenodesis technique using bone tunnels. Three patients were excluded due to insufficient data to calculate the functional scores. The final study sample comprised 21 patients and 23 shoulders. Clinical and functional outcomes were evaluated based on the American Shoulder and Elbow Surgeons (ASES) Score and the Long Head of Biceps (LHB) Score. Additionally, the main indications for the procedure and potential complications were thoroughly assessed. Results The average follow-up time was four years and, of the 21 patients (23 shoulders), 19 (82.6%) were male and 4 (17.4%) were female shoulders, with a mean age of 41.6 years. The main indication for surgery was superior labral anterior to posterior injury in 12 (52.2%) cases, followed by subluxation and tenosynovitis. No case presented aesthetic deformity or pain on palpation at the LHB. Patients showed significant improvement in the ASES score (average from 75.13 to 98.52) and LHB score (average from 68.82 to 98.34). Conclusion The subpectoral tenodesis technique is a safe procedure, with good clinical and functional outcomes for the treatment of proximal biceps pathologies.

The Incidence of Popeye Deformity After Soft-Tissue Biceps Tenodesis Is Comparable to Biceps Anchor Tenodesis and Lower Than Biceps Tenotomy During Arthroscopic Rotator Cuff Repair

PURPOSE

To compare clinical and radiologic outcomes between biceps anchor tenodesis (AT), biceps soft-tissue tenodesis (ST), and biceps tenotomy (TT) for patients with concomitant rotator cuff repair (RCR).

METHODS

This retrospective study reviewed patients who underwent arthroscopic RCR for full-thickness rotator cuff tears with AT, ST, or TT with minimum 2-year follow-up. All biceps procedures were performed arthroscopically, and ST consisted of fixation to the transverse humeral ligament. We excluded massive rotator cuff tears, additional biceps procedures, and revisions. Patient-reported outcome measures (PROMs) (visual analog scale [VAS] pain score, VAS functional score, American Shoulder and Elbow Surgeons score, and Constant score) and elbow flexion (EF) strength were evaluated preoperatively and at final follow-up.

RESULTS

A total of 155 patients (50 AT, 52 ST, and 53 TT patients) were included in this study. The AT group was younger (mean age, 58.7 ± 6.3 years in AT group, 67.6 ± 5.0 years in ST group, and 66.1 ± 5.3 years in TT group) and had a lower proportion of female patients (13 [26.0%] in AT group, 31 [59.6%] in ST group, 39 [73.6%] in TT group) than the ST and TT groups (all P < .001). At final follow-up, PROM scores were significantly improved in all 3 groups (all P < .001). The VAS pain score (P = .134), VAS functional score (P = .616), and American Shoulder and Elbow Surgeons score (P = .093) at final follow-up showed no significant differences between the 3 groups. The Constant score and EF strength were significantly higher in the AT group than in the ST and TT groups preoperatively (P = .009 for Constant score, P = .033 for EF strength) and at final follow-up (P < .001 for Constant score, P < .001 for EF strength). There was no significant difference in mean improvement in PROM scores and EF strength or in the proportion of achievement of the minimal clinically important difference. The incidence of Popeye deformity was significantly higher in the TT group (n = 11, 20.8%) than in the AT group (n = 3, 5.8%) and ST group (n = 4, 8.0%) (P = .035). Regression analysis showed that TT (odds ratio, 15.6; P < .001) and male sex (odds ratio, 103.9; P < .001) were associated with Popeye deformity and that ST (coefficient, -0.51; P = .035) was associated with bicipital groove pain.

CONCLUSIONS

Biceps AT, ST, and TT during arthroscopic RCR showed good clinical outcomes. Although there was a possibility of selection bias, there was no significant difference in mean improvement in clinical outcomes between the 3 long head of the biceps tendon procedures. The incidence of Popeye deformity was higher in the TT group, and that of biceps groove pain was higher in the ST group.

All-Suture Anchor Techniques for Biceps Tenodesis Are Noninferior in End-Cycle Stiffness to an Interference Screw Technique; However, Secondary Outcomes, Such as Ultimate Failure Load, Yield Load, Creep, and Load-to-Failure Stiffness, Are Inferior in an Ovine Model

Purpose

To assess the biomechanical performance of 2 simplified loop-and-tack biceps tenodesis techniques, all-suture anchor and all-suture anchor with a button, compared with the interference screw technique in an ovine model.

Methods

Twenty-one biceps tenodesis procedures were executed on the humeri and flexor digitorum profundus tendons of skeletally mature, female sheep. Limbs were evenly randomized into 2 experimental groups (all-suture anchor with or without button) and 1 control group (interference screw). Cyclic loading followed by a load-to-failure test was conducted. The primary outcome metric was end-cycle stiffness, or stiffness measured at the end of cyclic loading, because it modeled the resistance of the construct to the lower-force activities of postoperative physical therapy. Secondary metrics included ultimate failure load (UFL), yield load, creep, and load-to-failure stiffness. End-cycle stiffness difference-of-means testing was conducted with a minimal clinically important difference threshold of -15 N/mm (-1.5 kg/mm). Groups were compared using analysis of variance for all recorded variables.

Results

Both the all-suture anchor techniques, without a button and with a button, were found to be noninferior in end-cycle stiffness to the interference screw technique (-5.2 N/mm [95% confidence interval, -13.6 to 3.3 N/mm] and -3.8 N/mm [95% confidence interval, -12.5 to -4.9 N/mm], respectively) with a minimal clinically important difference of -15 N/mm. The all-suture techniques showed significantly lower UFL, lower yield load, greater creep, and lower load-to-failure stiffness (P < .001, P < .001, P = .002, and P < .001, respectively). Tendon dimensions did not vary significantly across groups.

Conclusions

Under subfailure loading conditions, the all-suture anchor techniques with a button and without a button showed end-cycle stiffness noninferiority to an interference screw technique; however, these techniques were inferior in all secondary outcomes, including significantly lower UFL, lower yield load, greater creep, and lower load-to-failure stiffness.

Clinical Relevance

The all-suture anchor approaches with a button and without a button may retain the natural length-tension dynamics of the long head of the biceps tendon because fixation can occur before the release of the tendon origin. Additionally, they may offer a simpler and more cost-effective alternative to prevailing arthroscopic methods.

Tenodesis of the Long Head of the Biceps Tendon Has No Detrimental Impact on the Postoperative Outcome After Supraspinatus Tendon Reconstruction

Introduction While several studies have compared tenotomy and tenodesis, few studies have examined whether performing a tenodesis of the long head of the biceps (LHB), when indicated, in patients who have undergone rotator cuff reconstruction has a detrimental impact on clinical and radiological postoperative outcomes. The present study aimed to investigate whether performing a tenodesis of the LHB has a damaging effect on the clinical and radiological outcome after rotator cuff reconstruction. Material and methods Fifty-one patients surgically treated for supraspinatus (SSP) tendon tears were included. All included patients received a reconstruction of the SSP, depending on the LHB surgery performed, patients were divided into two groups: 1) with concomitant tenodesis of the LHB and 2) without surgery of the LHB. Western Ontario Rotator Cuff Index (WORC), American Shoulder and Elbow Surgeons Shoulder Score (ASES), Constant, Oxford, and LHB scores were assessed at 2.3 ± 0.3 years postoperatively. All patients underwent clinical examination, including range of motion and force measurements. Furthermore, patients received an MRI scan of the operated shoulder two years postoperatively. Two blinded observers independently analyzed the integrity and quality of the rotator cuff on postoperative MRI using Sugaya and Castricini classifications. Clinical and radiological results were compared between both groups. Results All analyzed clinical scores, ranges of motion, and force measurements revealed no difference between both groups. Except for fatty infiltration (0° = 81% (21 of 26) vs. 68% (17 of 25); 1° = 15% (four of 26) vs. 28% (seven of 25); 2° = 4% (one of 26) vs. 4% (one of 25); and 3° = 0% (0 of 26) vs. 4% (one of 25); p < 0.01), no differences between both groups concerning the integrity (re-rupture rate = 27% (seven of 26) vs. 20% (five of 25); p = 0.39) and quality of the SSP tendon were found. Conclusions Tenodesis of the LHB performed in addition to rotator cuff repair is not associated with detrimental clinical outcomes than rotator cuff repair without surgery of the LHB. Except for fatty infiltration, which was lower in the tenodesis group, the results of the present study suggest that concomitant tenodesis of the LHB produces in patients who received rotator cuff repair have no detrimental effect in terms of clinical outcomes and re-rupture rates as well as tendon quality. Therefore, when indicated, simultaneous tenodesis of the LHB appears to be a safe and effective procedure that has no negative impact on the postoperative outcome after SSP tendon reconstruction.

One-Step Release Technique for Tendon Extraction During Biceps Tenodesis

All biceps tenodesis techniques involving extra-articular tendon preparation consist of 2 distinct steps for tenotomy and tendon grasping. These 2 maneuvers are performed by different instruments. A single-step tendon release technique is described for both arthroscopic and open shoulder surgery. This technique finds application in arthroscopic proximal suprapectoral tenodesis, open treatment of proximal humerus fractures, and suprapectoral mini-open tenodesis. Herein, we describe an arthroscopic biceps tenodesis technique that combines the actions of cutting and gripping the tendon in a single step.

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

BACKGROUND

Tenodesis of the long head of the biceps (LHB) is commonly undertaken during arthroscopic rotator cuff repair. We assessed the clinical and structural outcomes after high arthroscopic tenodesis (HAT) or mini-open subpectoral tenodesis (ST). We hypothesized that the clinical and structural results after HAT and ST are similar.

METHODS

We included 40 patients with rotator cuff tear and LHB tendinopathy. Twenty patients (7 women and 13 men; mean age: 57.9 years; range: 56-63 years) were treated using HAT, and 20 patients (8 women and 12 men; mean age: 58.5 years; range: 55-64 years) were treated using ST. Functional evaluation was performed preoperatively and at 6 weeks, 6 months, and 1 year after surgery, using the Constant Murley Score and Simple Shoulder Test scores; the LHB was evaluated using the LHB score. A Visual Analogue Scale was administered to all patients preoperatively and 2 days after surgery.

RESULTS

The postoperative total and pain subscale's Constant scores were significantly higher in the ST group. Moreover, 2 LHB score values were significantly different between the groups. The postoperative LHB total score in the ST and HAT groups averaged 86.9 ± 4.1 (mean ± SD) points and 73.3 ± 6.4 points, respectively. The Pain/Cramps subscale in the ST and HAT groups averaged 47.1 ± 5.9 and 33.2 ± 4.6 points, respectively. The 2 groups showed no difference in Visual Analogue Scale values (5.5 in the HAT group; 5.8 in the ST group) postoperatively. One patient in the HAT group reported a secondary onset of Popeye deformity.

CONCLUSION

Both high arthroscopic and mini-open ST of the LHB tendon produced reliably good functional results, but the ST group was associated with better postoperative clinical outcomes.

Outcomes of Biceps Tenodesis Variations With Concomitant Rotator Cuff Repair: A Multicenter Database Analysis

Background

Studies to date comparing biceps tenodesis methods in the setting of concomitant rotator cuff repair (RCR) have demonstrated relatively equivalent pain and functional outcomes.

Purpose

To compare biceps tenodesis constructs, locations, and techniques in patients who underwent RCR using a large multicenter database.

Study Design

Cohort study; Level of evidence, 3.

Methods

A global outcome database was queried for patients with medium- and large-sized tears who underwent biceps tenodesis with RCR between 2015 and 2021. Patients ≥18 years of age with a minimum follow-up of 1 year were included. The American Shoulder and Elbow Surgeons, Single Assessment Numeric Evaluation, visual analog scale for pain, and Veterans RAND 12-Item Health Survey (VR-12) scores were compared at 1 and 2 years of follow-up based on construct (anchor, screw, or suture), location (subpectoral, suprapectoral, or top of groove), and technique (inlay or onlay). Nonparametric hypothesis testing was used to compare continuous outcomes at each time point. The proportion of patients achieving the minimal clinically important difference (MCID) at the 1- and 2-year follow-ups were compared between groups using chi-square tests.

Results

A total of 1903 unique shoulder entries were analyzed. Improvement in VR-12 Mental score favored anchor and suture fixations at 1 year of follow-up (P = .042) and the onlay tenodesis technique at 2 years of follow-up (P = .029). No additional tenodesis comparisons demonstrated statistical significance. The proportion of patients with improvement exceeding the MCID did not differ based on tenodesis methods for any outcome score assessed at the 1- or 2-year follow-up.

Conclusion

Biceps tenodesis with concomitant RCR led to improved outcomes regardless of tenodesis fixation construct, location, or technique. A clear optimal tenodesis method with RCR remains to be determined. Surgeon preference and experience with various tenodesis methods as well as patient clinical presentation should continue to guide surgical decision-making.

Translation and Cultural Adaptation to Portuguese of the Long Head of Biceps Tendon Score

Objective  To translate and culturally adapt the Long Head of Biceps Tendon (LHB) score into Brazilian Portuguese. Methods  The process involved translations by professionals fluent in the target language, followed by independent back translations. Next, a committee compared the original and translated versions, pretested the final version, and concluded it. Results  We translated and adapted the questionnaire according to the proposed methodology. In the first version in Portuguese (VP1) there was divergence regarding the translation of twelve terms. Compared to the original version, the back translation of VP1 presented eight diverging terms. A committee prepared a second version in Portuguese (VP2) and applied it to a pretest group consisting of 30 participants. Finally, we conceived the third version in Portuguese, called LHB-pt. Conclusion  The translation and cultural adaptation into Brazilian Portuguese of the LBH score was successfully accomplished.

Biceps Tenodesis in Patients Age 35 Years and Younger Yields Favorable Clinical Outcomes With Variable Rates of Return to Sport and Complications: A Systematic Review

PURPOSE

To systematically evaluate reported clinical outcomes, return-to-sport (RTS) rates, and complications following biceps tenodesis in patients aged 35 years and younger and compare outcomes between overhead and nonoverhead athletes.

METHODS

A literature search was performed by querying Scopus, EMBASE, and PubMed computerized databases from database inception through August 2022 in accordance with the 2020 Preferred Reporting Items for Systematic Review and Meta-Analysis guidelines. Studies that evaluated clinical outcomes following biceps tenodesis in patients aged 35 years or younger were included. Study quality was assessed via the Methodological Index for Non-Randomized Studies criteria. Clinical outcomes, RTS rates, and complications were aggregated.

RESULTS

Nine studies from 2011 to 2022 comprising 161 patients (mean age, 25 years; range, 19.7-28.9 years) were included. At an average follow-up of 59 months, postoperative American Shoulder and Elbow Surgeons score ranged from 81.6 to 96 and the mean visual analog scale score ranged from 0 to 2.1. Mean overall RTS rate ranged from 35% to 100% for the entire patient cohort 35% to 86% among overhead athletes, and 46% to 100% among nonoverhead athletes. Among the overhead athletes, 24 were baseball pitchers. 17% to 100% able to return to sport at any level. Complications were reported in 0% to 19% of patients. 0 to 18% of patients underwent revision surgery.

CONCLUSIONS

Biceps tenodesis in patients 35 years of age and younger yields a wide variability in reported RTS rates, excellent clinical outcome scores, and low but variable reported rates of complications, reoperations, and failure.

A Standardized Operative Protocol for Fixation of Proximal Humeral Fractures Using a Locking Plate to Minimize Surgery-Related Complications

The current literature suggests that up to 55% of complications after plate osteosynthesis treatment for patients with proximal humerus fractures are attributed to the surgical procedure. The hypothesis of this study was that a standardized surgical protocol would minimize surgery-related adverse events. This prospective cohort study included 50 patients with a mean age of 63.2 (range 28-92) years treated by one single surgeon using a previously published standardized surgical protocol. Clinical and radiological follow-up examinations were conducted for up to 24 months using Constant-Murley Score (CS), Subjective Shoulder Value (SSV) and radiographs in true anteroposterior, axial and y-view. Finally, CS was 73.9 (standard deviation [SD]: 14.0) points (89% compared to the uninjured shoulder), and SSV was 83.3% (SD: 16.7) at two years of follow-up. Postoperative radiologic evaluation revealed no primary surgical-related or soft-tissue-related complications (0%). The main complications were secondary, biological complications (20%), largely represented by avascular necrosis (8%). Eight patients underwent revision surgery, mainly for implant removal. In addition, a total of four patients were revised using a hemiarthroplasty (n = 2), reverse shoulder arthroplasty (n = 1) or re-osteosynthesis. The use of our standardized surgical technique on proximal humerus fractures improves fixation with regard to primary stability and prevents primary, surgical-technique-related complications. The subjective grading of a high level of difficulty surgery was associated with more complications.

Fast Arthroscopic Biceps Tenodesis Without Penetrating Grasper

Long head of the biceps pathology is a common cause of shoulder pain and dysfunction. Surgical treatment can be either a tenotomy or a tenodesis. Long-term results may be similar in both surgical techniques; however, the latest systematic reviews indicate that tenodesis offers superior clinical and functional results in young patients and athletes. Considering the favorable results with the biceps tenodesis, we present this arthroscopic tenodesis in which the long head of the biceps is fixed in the bicipital groove with an all-suture anchor passed directly through the tendon, providing a stable and fast fixation without using penetrating grasper.

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

BACKGROUND

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

METHODS

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

RESULTS

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

CONCLUSION

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

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 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.

Improvement in long head of biceps function and lower rate of biceps deformities after subpectoral tenodesis with cortical button and interference screw vs. arthroscopic tenotomy: a 4-year follow-up

Background

This study aimed to evaluate clinical, cosmetic, and strength midterm outcomes in arthroscopic biceps tenotomy and subpectoral biceps tenodesis using bicortical endobutton and interference screw.

Methods

In this retrospective study, inclusion criteria were long head of the biceps (LHB) pathologies treated either with tenotomy or an additional tenodesis. Postoperative assessment included Long Head of Biceps Score (LHBS), age-adjusted Constant-Murley Score, and Subjective Shoulder Value. Elbow flexion and forearm supination strength were measured. The presence of Popeye sign, cramps, and tenderness over the bicipital grove was evaluated. Statistical analysis of continuous variables without normal distribution was performed using Mann-Whitney U test. Grouped analysis was performed using 2-way analysis of variance. Binominal data were analyzed using chi-square test.

Results

A total of 73 patients with a mean age of 63.1 ± 9.6 years and a mean follow-up of 4.2 ± 0.5 years were included. Tenotomy was performed in 34 and tenodesis in 39 patients. Tenodesis group displayed a significantly higher LHB score (P = .0006), but no significant differences were detected for the age-adjusted Constant-Murley Score and Subjective Shoulder Value. Tenodesis group showed a significantly lower rate of Popeye deformities (P = .0007) and tenderness over the bicipital groove (P = .004). Patients from the tenotomy group with biceps deformity showed a significantly higher mean contralateral supination strength (P = .002) but no significant difference in contralateral elbow flexion compared with patients without biceps deformity. There was one (1.4%) complication in the tenotomy group (postoperative shoulder stiffness).

Conclusion

Both techniques resulted in comparable outcome scores on preselected patients, with tenodesis leading to better LHB function. Tenodesis did not improve elbow flexion and forearm supination strength beyond the tenotomy; however, it reduced the frequency of biceps deformities and tenderness over the bicipital groove. Patients with a strong contralateral forearm supination strength could be at risk of developing a biceps deformity after tenotomy.

Tenodesis yields better functional results than tenotomy in long head of the biceps tendon operations-a systematic review and meta-analysis

BACKGROUND

Pathology of the long head of the biceps tendon (LHBT) is a common disorder affecting muscle function and causing considerable pain for the patient. The literature on the two surgical treatment methods (tenotomy and tenodesis) is controversial; therefore, our aim was to compare the results of these interventions.

METHODS

We performed a meta-analysis using the following strategy: (P) patients with LHBT pathology, (I) tenodesis, (C) tenotomy, (O) elbow flexion and forearm supination strength, pain assessed on the ten-point Visual Analog Scale (VAS), bicipital cramping pain, Constant, ASES, and SST score, Popeye deformity, and operative time. We included only randomized clinical trials. We searched five databases. During statistical analysis, odds ratios (OR) and weighted mean differences (WMD) were calculated for dichotomous and continuous outcomes, respectively, using the Bayesian method with random effect model.

RESULTS

We included 11 studies in the systematic review, nine of these were eligible for the meta-analysis, containing data about 572 patients (279 in the tenodesis, 293 in the tenotomy group). Our analysis concluded that tenodesis is more beneficial considering 12-month elbow flexion strength (WMD: 3.67 kg; p = 0.006), 12-month forearm supination strength (WMD: 0.36 kg; p = 0.012), and 24-month Popeye deformity (OR: 0.19; p < 0.001), whereas tenotomy was associated with decreased 3-month pain scores on VAS (WMD: 0.99; p < 0.001). We did not find significant difference among the other outcomes.

CONCLUSION

Tenodesis yields better results in terms of biceps function and is non-inferior regarding long-term pain, while tenotomy is associated with earlier pain relief.

The IBTIS score; a new prognostic score for arthroscopic biceps tenotomies

INTRODUCTION

Shoulder pain associated with tendinopathy of the long head of biceps (LHB) is common. Surgical treatment with arthroscopic tenotomy of the LHB has been shown to be effective. However, it's efficacy is inconsistent. The objective of this study was to assess the pre-operative clinical and radiological prognostic factors of arthroscopic tenotomy of the long head of biceps, and to establish a predictive score for good responses to treatment; the IBTIS score (Isolated Biceps Tenotomy Index Score).

HYPOTHESIS

Prognostic factors representing a good response to treatment of LHB tendinopathy by arthroscopic tenotomy exist.

MATERIALS AND METHODS

We conducted a retrospective monocentric study including 64 patients who underwent surgery of the LHB by arthroscopic tenotomy (with or without tenodesis) between January 2018 and March 2020. We identified 2 patient groups (good responder group and poor responder group) from a 3-month post-operative clinical assessment, which included a subjective assessment comprising Single Shoulder Value (SSV), Constant score, C-Test, and pain level. Prognostic factors of a good response were then sought from the 2 groups using interviews, clinical examinations and pre-operative imaging. Based on these findings, a predictive score for a good response was established.

RESULTS

All evaluation criteria demonstrated post-operative improvement: mean SSV (72.2 vs 50.7; p<0.001), relative constant (78.2 vs 64.3; p<0.001), pain level (3.2 vs 7; p<0.001) and C-Test (94.1 vs 85.6; p=0.07). 34 patients (58.6%) were considered good responders, while 24 patients (41.38%) were considered poor responders. There was a trend towards a favourable result for: age>65 years (p=0.01), rotator cuff rupture on preoperative imaging (p=0.01), Cross Arm Test (p=0.02), nocturnal pain (p=0.08), Yergason's test (p=0.16) and Speed's Test (p=0.22). Manual labour appeared to be an unfavourable factor (p=0.07). These factors were incorporated into the 10-point IBTIS score. A score greater than 5 was associated with a favourable result in more than 80% of patients (p<0.001).

DISCUSSION

Our score consists of 7 items. We identified 7 pre-operative prognostic factors for a good result after LHB tenotomy. Over 65 years of age was found to be statistically significant in univariate analysis, as was visualization of rotator cuff rupture on pre-operative imaging. The Cross Arm Test was included given its high statistical significance. The Speed's Test and Yergason's Test are ubiquitous in the literature. Nocturnal pain was found in more than 80% of patients. Undertaking manual labour represented an unfavourable prognostic factor after arthroscopic surgery of the LHB.

CONCLUSION

The IBTIS score (Isolated Biceps Tenotomy Index Score) is a pre-operative clinico-radiological score for the surgical treatment of arthroscopic tenotomy of the long head of biceps. Further studies are required to validate its prognostic accuracy.

Reliable Clinical and Sonographic Outcomes of Subpectoral Biceps Tenodesis Using an All-Suture Anchor Onlay Technique

PURPOSE

To evaluate the clinical outcomes and structural integrity of primary subpectoral biceps tenodesis using an all-suture anchor onlay technique for long head of the biceps (LHB) tendon pathology.

METHODS

We conducted a retrospective case series with prospectively collected data of patients who underwent primary, isolated subpectoral biceps tenodesis with a single all-suture anchor onlay fixation between March 2017 and March 2019. Outcomes were recorded at a minimum follow-up of 12 months based on assessments of the American Shoulder and Elbow Surgeons (ASES) score, LHB score, and elbow flexion strength and supination strength measurements. The integrity of the tenodesis construct was evaluated using ultrasound.

RESULTS

Thirty-four patients were available for clinical and ultrasound examination at a mean follow-up of 18 ± 5 months. The mean ASES score significantly improved from 51.0 ± 14.2 points preoperatively to 89.8 ± 10.5 points postoperatively (P < .001). The minimal clinically important difference for the ASES score was 8.7 points, which was exceeded by 31 patients (91.2%). The mean postoperative LHB score was 92.2 ± 8.3 points. Regarding subcategories, an average of 47.2 ± 6.3 points was reached for "pain/cramps"; 26.4 ± 6.1 points, "cosmesis"; and 18.6 ± 2.6 points, "elbow flexion strength." Both elbow flexion strength and supination strength were similar compared with the nonoperated side (P = .169 and P = .210, respectively). In 32 patients, ultrasound examination showed an intact tenodesis construct, whereas 2 patients (5.9%) sustained failure of the all-suture anchor fixation requiring revision.

CONCLUSIONS

Primary subpectoral biceps tenodesis using an all-suture anchor onlay technique for pathology of the LHB tendon provides reliable clinical results and a relatively low failure rate (5.9%).

Histopathology of long head of biceps tendon removed during tenodesis demonstrates degenerative histopathology and not inflammatory changes

Background

The aim of this study is to describe and quantitatively analyze the histopathology of proximal long head biceps (LHB) tendinopathy in patients who have undergone LHB tenodesis. The hypothesis is that severe histopathologic changes of the LHB tendon (LHBT) will most likely be reflected with improved postoperative clinical outcomes.

Methods

The study included patients with isolated LHB tendinopathy or LHB tendinopathy associated with concomitant shoulder pathologies. All had failed conservative treatment (12 months) and had a positive pain response (> 50% reduction) pre-operatively after LHB tendon injection with local anesthetic. All underwent biceps tenodesis procedure between 2008 and 2014. Tendon specimens were collected and histologically analyzed with the semi-quantitative Bonar scoring system. Minimum follow-up time was 1 year. A subset of patients was retrospectively reviewed postoperatively and evaluated employing visual analogue score (VAS), short form survey (SF-12), American Shoulder and Elbow Surgeon (ASES) score, Disability of Arm, Shoulder and Hand (DASH) score, and Oxford Shoulder Score (OSS) and postoperative return to work status.

Results

Forty-five biceps tendon specimens were obtained from 44 patients (mean age 50 ± 9.6 years). Histopathological analyses demonstrated advanced degenerative changes with myxoid degeneration and marked collagen disorganization. Minimal inflammation was identified. There were no regional differences in histopathological changes. Clinical outcomes did not correlate significantly with severity of histopathologic changes.

Conclusions

This study confirms that LHBT specimens in patients undergoing tenodesis demonstrate with the use of the Bonar score histopathologic changes of chronic degeneration and not inflammation. The correct histopathologic terminology for this process is LHB tendinosis. The histopathological changes appear uniform throughout the entire length of the LHBT which may inform the nature of the procedure performed.

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.

[Effectiveness comparison of arthroscopic intertubercular groove and open subpectoral tenodesis for long head of biceps tendon tendinopathy]

OBJECTIVE

To compare the effectiveness of arthroscopic intertubercular groove and open subpectoral tenodesis in treatment of long head of biceps tendon (LHBT) tendinopathy.

METHODS

A clinical data of 80 patients with LHBT tendinopathy who were admitted between June 2013 and May 2017 and met the selection criteria was retrospectively analyzed. After cutting LHBT under arthroscopy, the arthroscopic intertubercular groove tenodesis was performed in 40 cases (group A) and open subpectoral tenodesis was performed in 40 cases (group B). There was no significant difference in the gender, age, side of the affected shoulder joint, disease duration, and preoperative pain visual analogue scale (VAS) score, Constant score, American Society of Shoulder and Elbow Surgery (ASES) score, Disability of Arm, Shoulder, and Hand (DASH) score, LHBT score (LHBS) between the two groups ( P>0.05). The operation time and the scores of shoulder joint pain and function at 12 months after operation were compared between the two groups.

RESULTS

The operation time was (3.6±2.5) minutes in group A and (8.5±2.3) minutes in group B, showing a significant difference ( t=18.584, P=0.000). The incisions of the two groups healed by first intention, and there was no complication such as infection or thrombosis. All patients were followed up. The follow-up time was 24-30 months (mean, 26.0 months) in group A and 24-31 months (mean, 26.0 months) in group B. Both Speed test and Yergason test were negative at 3 months after operation. MRI showed that there was no obvious effusion around the LHTB and no dislocation of LHTB. At 12 months after operation, the VAS score, Constant score, ASES score, DASH score, and LHBS score of the two groups all improved when compared with preoperative ones ( P<0.05), and there was no significant difference in the differences before and after operation between the two groups ( P>0.05). No Popeye sign appeared during the follow-up.

CONCLUSION

The arthroscopic intertubercular groove and open subpectoral tenodesis can effectively relieve shoulder pain and improve function, but the former has shorter operation time and less trauma.

Evaluation of Biceps Tenotomy or Tenodesis on Fatty Infiltration of the Biceps Muscle

Objective  The objective of the present study was to determine whether there is fatty infiltration (FI) of the biceps brachii muscle mass after tenotomy or tenodesis for the treatment of tendon injuries in the long head of the biceps and to establish a relationship between FI with changes in the length of muscle fibers.

Methods  Clinical and imaging analysis of 2 groups of patients (biceps tenodesis [16 patients] and biceps tenotomy [15 patients]). In both groups, we compared the findings on the contralateral side of each patient (control group). All patients had undergone unilateral biceps tenodesis or tenotomy, with postoperative follow-up of > 1 year. Magnetic resonance imaging (MRI) was performed on both arms of each patient following a specific protocol. Strength of elbow flexion was measured with a manual dynamometer, and the results were subjected to statistical analysis.

Results  The mean postoperative period before the MRI was 5 years, and no case of FI was observed in the anterior compartment of either arm of the evaluated patients. Seven patients had moderate or severe deformity in the operated arm. We found no significant relationship between arm deformity ( p  = 0.077), flexion strength percentage ( p  = 0.07) or pain on palpation of the bicipital groove ( p  = 0.103).

Conclusion  None of the evaluated patients had evidence of FI in the muscle mass of the anterior arm compartment after the procedures. It was not possible to establish a correlation between the discrepancy of the biceps muscle length measured by MRI and the presence of FI in the anterior compartment of the arm.

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.

Arthroscopic Biceps to Subscapularis Tenodesis: A Surgical Technique

A wide variety of techniques are available for tenodesis of the long head of the biceps tendon, and current literature does not favor any one in particular. We present a simple method for arthroscopic soft tissue biceps tenodesis that uses the subscapularis tendon as the anchor. This 5-step technique is time-efficient, technically simple, cost effective, and does not require powered instruments or specialized implants.

The Loop Tenodesis Procedure-From Biomechanics to First Clinical Results

(1) Introduction: Several surgical therapy options for the treatment of pathologies of the long biceps tendon (LHB) have been established. However, tenotomy, as well as established tenodesis techniques, has disadvantages, such as cosmetic deformities, functional impairments and residual shoulder pain. This study presents the first clinical and structural results of the recently introduced loop tenodesis procedure for the LHB, developed to overcome these issues. (2) Methods: 37 patients (11 women, 26 men, mean age 52 years), who underwent loop tenodesis of the LHB were examined six months after surgery. For the clinical evaluation the Constant score, as well as the LHB score, were used, complemented by elbow flexion and supination strength measurements. The integrity of the tenodesis construct was evaluated indirectly by sonographic detection of the LHB in the bicipital groove. (3) Results: Both, the overall Constant score as well as the LHB score showed significant improvements six months postoperatively, as compared to the preoperative value. Fourteen patients (38%) presented an examiner-dependent upper arm deformity, although only five patients (13%) reported subjective cosmetic deformities. Both, flexion and supination strength were preserved compared to the preoperative level. In 35 patients (95%), the tenodesis in the bicipital groove was proofed sonographically. (4) Conclusion: The loop tenodesis of the LHB provides good-to-excellent overall clinical results after a short-term follow-up of six month. The incidence of cosmetic deformities was inferior compared to conventional therapy options (tenotomy and anchor tenodesis).

The majority of patients return to athletic activity following biceps tenodesis

PURPOSE

Biceps tenodesis is widely used as a primary treatment for long head of the biceps brachii pathology and superior labral anterior and posterior (SLAP) lesions. However, rates and timing of full return to sports (RTSs)/duty have not been systematically analysed. This systematic review examines the literature to ascertain the rate and timing of return to athletic activity, and the availability of specific criteria for safe return to atheletic activity following the biceps tenodesis.

METHODS

Based on PRISMA guidelines, this systematic review utilised the EMBASE, MEDLINE, and The Cochrane Library Databases. Eligible for inclusion were clinical studies reporting on return to athletic activity following biceps tenodesis. Statistical analysis was performed using SPSS.

RESULTS

This review identified 17 studies including 374 cases meeting the inclusion criteria. The majority of patients were men 260 (69.7%), with an median age of 42.2 years (range 16-88) and a mean follow-up of 37.4 months. The overall rate of RTS was 217/269 (80.7%), with 43/59 (72.9%) returning to the same level. In overhead athletes, the overall rate of return to play was 39/49 (79.6%). Among military personnel, the overall rate of return to duty was 61/74 (82.4%). The average time to RTS was 5.4 (range 3-11) months. 10 (58.8%) Studies reported a recommended time window within which patients were allowed to return to full activity. Specific criteria for return to play were not reported in any of the identified studies.

CONCLUSION

While overall rate of return to athletic activity was reportedly high following biceps tenodesis, one in four patients were not able to resume athletic activity at the same level. At present, there is no objective assessment of when patients can return to full activity reported in the literature.

Adhesion of the Long Head of the Biceps Tendon: A Case Series

Purpose

To present the clinical and imaging findings and results of treatment in patients with intra-articular long head of the biceps tendon (LHBT) adhesion to the undersurface of the rotator cuff found incidentally during shoulder arthroscopy.

Methods

Patients with intra-articular LHBT adhesion to the undersurface of the rotator cuff found incidentally during arthroscopy were included with a minimal 2-year follow-up. Demographic data, images, and physical examinations were recorded. LHBT release, tenotomy, or tenodesis were performed according to the patient’s age and surgeon’s preference.

Results

Twelve patients were included in the study. All of them presented with chronic anterior shoulder pain and positive Speed and O’Brien tests. The average age was 46.8 ± 17 years (range 20-79 years) and the pain sustained from 6 to 96 (average 25.5 ± 28.6) months. Before the operation, 6 patients had a positive Jobe’s test, 1 had a positive lift-off test, and all had positive O’Brien and Speed tests and tenderness over the LHBT. Three release, 4 tenotomy, and 5 LHBT tenodesis were done in addition to other procedures if needed. All range of motion except external rotation, pain visual analog score, and functional outcome scores showed significant improvement at 6 months after surgery. There were no significant differences in range of motion and functional scores between 6 months and 12 months postoperatively. No difference was found in LHBT scores at 6 and 12 months after the operation. Magnetic resonance imaging revealed thickened coracohumeral ligament overlying the LHBT.

Conclusions

Patients who had intra-articular LHBT adhesion to the undersurface of the rotator cuff and underwent release of the adhesion around LHBT, tenotomy, or tenodesis all had good clinical outcomes. The lesion was observed in 2.2% of all shoulder arthroscopies. Although difficult to diagnose before surgery, surgeons should be aware of this unusual condition in patients with chronic and insidious anterior shoulder pain.

Anatomic limitations of biceps tenodesis using an interference screw for Asian people: a cadaveric study

Background

Biceps tenodesis using an interference screw has been commonly performed in clinical practice because of pathologic changes. Especially, the tenodesis distal to the bicipital groove, such as suprapectoral tenodesis (SPT) and subpectoral tenodesis (SBT), has been performed to avoid residual anterior shoulder pain. However, the techniques were developed based on research tested on Western population, and it is unknown whether they are applicable to Asian individuals, who have a smaller humerus than Western. The purpose of this study was to investigate the anatomic limitations of the biceps tenodesis using an interference screw for Asians.

Methods

We analyzed 22 fixed Japanese cadavers. We measured the length of the suprapectoral tenodesis zone (STZ), which is the area from the distal end of the lesser tuberosity to the proximal border of the insertion of the pectoralis major muscle tendon (PMMT) along the course of the biceps tendon, for the SPT. We also measured the bone tunnel depths (BTDs) for the SPT just distal to the lesser tuberosity along the course of the biceps tendon and, similarly, for the SBT just distal to the PMMT insertion. Finally, we analyzed the sexual differences and correlations of the measured values with the entire humeral length.

Results

In 9 shoulders (40.9%), the proximal border of the PMMT insertion was attached more proximally than the distal end of the lesser tuberosity, and the length of the STZ was negative. The mean BTDs in the SPT and SBT zones were 19.6 and 14.9 mm, respectively. In 11 shoulders (50%), the BTD in the SBT zone was shorter than 15 mm. The lengths of the STZ or BTDs in the SPT and SBT zones did not show statistical differences between sexes and were not correlated with the entire humeral length.

Conclusion

Asian patients would have anatomic limitations as follows for the biceps tenodesis regardless of their sex or body size. In anomalous PMMT cases, when the SPT was performed just proximal to the PMMT insertion, the bone tunnel entered into the bicipital groove. On the other hand, when the SPT was performed distal to the lesser tuberosity, a part of the PMMT insertion would be injured. Regarding the SBT, an interference screw with a length of ≥12 mm, which is commonly used in Western countries, is too long for Asians.

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

Background:

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

Purpose:

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

Study Design:

Systematic review; Level of evidence, 4.

Methods:

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

Results:

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

Conclusion:

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

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.

Intra-articular arthroscopic biceps tenodesis with interference screw: clinical and isokinetic evaluation

Background

Although biceps tenodesis has been widely used to treat its pathologies, few studies looked at the objective evaluation of elbow strength after this procedure. The purpose of this study is to clinically evaluate patients submitted to long head of the biceps (LHB) tenodesis with interference screws through an intra-articular approach and analyze the results of an isokinetic test to measure elbow flexion and forearm supination strengths.

Methods

Patients who had biceps tenodesis were included in the study if they had a minimum follow-up of 24 months. Patients were excluded if they had concomitant irreparable cuff tears or previous or current contralateral shoulder pain or weakness. Postoperative evaluation was based on University of California-Los Angeles (UCLA) shoulder score and on measurements of elbow flexion and supination strength, using an isokinetic dynamometer. Tests were conducted in both arms, with velocity set at 60º/s with 5 concentric-concentric repetitions.

Results

Thirty-three patients were included and the most common concomitant diagnosis were rotator cuff tear (69%) and superior labrum anterior to posterior (SLAP) lesions (28%). The average UCLA score improved from 15.1 preoperatively to 31.9 in the final follow-up (P < .001). Isokinetic tests showed no difference in peak torque between the upper limbs. One patient had residual pain in the biceps groove. None of the patients had Popeye deformity. UCLA score and follow-up length did not demonstrate correlation with peak torque.

Conclusion

Arthroscopic proximal biceps tenodesis with interference screw, close to the articular margin, yielded good clinical results. Isokinetic tests revealed no difference to the contralateral side in peak torque for both supination and elbow flexion.

Arthroscopic tenodesis using a bioabsorbable interference screw and soft anchor: A case series of 60 patients

BACKGROUND

Various arthroscopic tenodesis techniques for the treatment of long head of the biceps tendon pathologic abnormalities have been described.

PURPOSE

This study evaluated the clinical outcomes of using a bioabsorbable interference screw and soft anchor for long head of the biceps tendon arthroscopic tenodesis.

METHODS

Sixty patients treated by this technique between February 2013 and March 2015 were followed up for at least 2 years. In our operative technique, after the bone hole was made just proximal to the pectoralis major, the soft anchor was inserted at the bottom of the hole. After tenotomy of the long head of the biceps tendon proximal to the bone hole, the tendon was fixed into the bottom of the hole temporarily using the soft anchor. Finally, the tendon was fixed in the hole with a bioabsorbable interference screw.

RESULTS

The UCLA score 15.1 points preoperatively and 32.4 points at follow-up (p < 0.05). The Constant 55.8 points preoperatively and 93.9 points at follow-up (p < 0.01). After biceps tenodesis, no cosmetic deformities were found in 56 patients (93.3%), and four patients (6.7%) had a Popeye deformity. On postoperative magnetic resonance evaluation, the long head of the biceps tendon was located on the bicipital groove without deviation in 53 cases (88.3%), on the bicipital groove with a partial deviation in 6 cases (10.0%), and outside the bicipital groove with complete deviation (dislocated) in 1 case (1.7%).

CONCLUSION

We found that arthroscopic biceps tenodesis using a soft anchor provided a reliable means for treating biceps pathology with no cosmetic deformities and with good clinical results.

Editorial Commentary: Biceps Tenodesis Fixation: Screw, Button, or None of the Above?

Clinical outcomes following shoulder subpectoral biceps tenodesis are generally favorable, with a very low complication rate (2%). One of the most devastating complications following this procedure is the occurrence of a proximal humerus fracture. Although all constructs have their unique advantages and disadvantages, creating a smaller bone hole while achieving good biomechanical outcomes is worth considering. This may be most advantageous in overhead-throwing athletes, tennis players, and/or volleyball athletes, who subject their shoulders to more torsional load due to the requirements of their sport. Thus, in addition to screws and buttons, smaller-diameter suture anchors could also be thoughtfully considered as a biceps tenodesis fixation option.

Osteogenesis and bone remodeling: A focus on growth factors and bioactive peptides

Bone is one of the most frequently transplanted tissues. The bone structure and its physiological function and stem cells biology were known to be closely related to each other for many years. Bone is considered a home to the well-known systems of postnatal mesenchymal stem cells (MSCs). These bone resident MSCs provide a range of growth factors (GF) and cytokines to support cell growth following injury. These GFs include a group of proteins and peptides produced by different cells which are regulators of important cell functions such as division, migration, and differentiation. GF signaling controls the formation and development of the MSCs condensation and plays a critical role in regulating osteogenesis, chondrogenesis, and bone/mineral homeostasis. Thus, a combination of both MSCs and GFs receives high expectations in regenerative medicine, particularly in bone repair applications. It is known that the delivery of exogenous GFs to the non-union bone fracture site remarkably improves healing results. Here we present updated information on bone tissue engineering with a specific focus on GF characteristics and their application in cellular functions and tissue healing. Moreover, the interrelation of GFs with the damaged bone microenvironment and their mechanistic functions are discussed.

Validity and Reliability of the Turkish Version of LHB Score

INTRODUCTION

Long head of biceps (LHB) pathologies are an important cause of pain and dysfunction. As LHB pathologies have specific components from other underlying or related pathologies, the LHB score is designed for an accurate assessment. The aim of this study was to adapt the LHB score into Turkish and to assess its validity and reliability.

MATERIALS AND METHODS

LHB score was translated and culturally adapted from English to Turkish, and then it was applied to 62 patients with biceps long head pathology. The reliability of the scale was checked through internal consistency and test-retest methods. Internal consistency was computed with Cronbach alpha value. Test-retest reliability was assessed using an intraclass correlation coefficient. American Shoulder and Elbow Surgeons Standard Shoulder Assessment Form and modified Constant-Murley score were used to analyze concurrent validity.

RESULTS

The Cronbach alpha value of the scale was found as .640. When the subsections of LHB score were computed separately, Cronbach alpha levels of pain/cramps and cosmesis sections were found as .753 and .774, respectively. The intraclass correlation coefficient value of the scale was found to be excellent (.940; P < .001). The total LHB score was determined to have a good positive correlation with the American Shoulder and Elbow Surgeons Standard Shoulder Assessment Form (.527) and Constant-Murley score (.516). But an excellent correlation was revealed between the pain/cramps section of LHB score and other pain sections in American Shoulder and Elbow Surgeons Standard Shoulder Assessment Form (.811) and Constant-Murley score (.816) (P < .001). There was an excellent correlation (.916) between cosmesis section and Popeye sign (P < .001). There was a moderate correlation (.469) between elbow-flexion strength section of LHB score and the digital handheld dynamometer outcomes (P < .001).

CONCLUSION

The Turkish version of the LHB is a valid and reliable tool, especially for biceps pathologies.

Double on-lay fixation using all suture-type anchor for subpectoral biceps tenodesis has favorable functional outcomes and leads to less cosmetic deformities than single on-lay fixation

PURPOSE

This study aimed to compare the clinical outcomes between single on-lay and double on-lay subpectoral biceps tenodesis (SPBT) using all-suture type anchor in patients with concomitant long head of the biceps tendon (LHBT) lesions and rotator cuff tears.

METHODS

The study included 130 patients who underwent SPBT using all-suture type anchor and arthroscopic rotator cuff repair. Single and double anchor on-lay fixations were performed in 69 patients (group A) and 61 patients (group B), respectively. In 16 patients of group A and 36 patients of group B, a metallic wire was embedded at tenodesis site and difference of wire location pre-and postoperatively was measured using simple radiography.

RESULTS

In both groups, the mean visual analogue scale (VAS) score during motion, the mean UCLA and constant scores significantly improved at the last follow-up (all p < 0.001). These scores were not significantly different between two groups. However, postoperatively, a significant difference was observed in the incidence of cosmetic deformity between two groups (p = 0.019). The cosmetic deformity was noted in 9 (13.0%) patients (Popeye deformity 7.2% and biceps softening 5.8%) in group A and 1 (1.6%) patient (Popeye deformity) in group B. In the subgroup analysis on biceps migration after the surgery, the mean migration distance of metal wire was 2.5 ± 3.0 mm in group A and 1.9 ± 2.6 mm in group B (n.s.). No patient had migration of > 10 mm.

CONCLUSIONS

SPBT using all-suture type anchor was a favorable treatment option for lesions of the LHBT with rotator cuff tear. The clinical relevance of this study is the finding that double on-lay fixation with all-suture type anchor would result less cosmetic deformity than the single on-lay fixation for those who need subpectoral biceps tenodesis.

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.

A meta-analysis comparing tenotomy or tenodesis for lesions of the long head of the biceps tendon with concomitant reparable rotator cuff tears

Background

The best treatment for lesions of the long head of the biceps tendon (LHBT) with concomitant reparable rotator cuff tears is still controversial. The purpose of the meta-analysis was to compare clinical outcomes of biceps tenotomy and tenodesis for LHBT lesions.

Methods

A literature retrieval was conducted in MEDLINE, Embase, and Cochrane Library from 1979 to March 2018. Comparative studies (level of evidence I or II) comparing tenotomy and tenodesis for LHBT lesions with concomitant reparable rotator cuff tears were included. Risk of bias for all included studies was assessed using the Cochrane Collaboration’s risk of bias tool. Clinical outcomes compared were Popeye sign, Constant score, VAS pain score, cramping pain, elbow flexion and forearm supination strength, and re-tear of the rotator cuff.

Results

Two randomized controlled trials (RCTs) and five prospective cohort studies (PCS) with 288 biceps tenotomy patients and 303 biceps tenodesis patients were included in this review. Tenotomy resulted in significantly greater rates of Popeye sign (RR, 2.70 [95% CI, 1.80 to 4.04]; P < 0.01) and a less favorable Constant score (MD, − 1.09 [95% CI, − 1.90 to − 0.28]; P < 0.01) compared to tenodesis. No significant heterogeneity was found between the two groups across all parameters except forearm supination strength.

Conclusions

The current evidence indicates that biceps tenodesis for LHBT lesions with concomitant reparable rotator cuff tears results in decreased rate of Popeye sign and improved Constant score compared to biceps tenotomy.

Arthroscopic All-Inside Biceps Tenodesis: Technique and Outcomes

The long head of the biceps tendon (LHBT) is a frequent source of disorders and pathology in the shoulder. Significant evidence is available on the management of disorders of the LHBT in the literature, and the LHBT is frequently addressed intraoperatively when involved in shoulder pathology. An all-arthroscopic, intra-articular biceps tenodesis with suture anchor fixation has several advantages that have not been well described previously, and it does not add significant morbidity to arthroscopic surgery to treat the rotator cuff or other sources of pain. Intra-articular LHBT tenodesis in the bicipital groove thus has advantages of less surgical time and a decreased bone footprint.

Novel implant-free loop Tenodesis vs. simple Tenotomy of the long biceps tendon - a biomechanical investigation

Background

Simple tenotomy and anchor tenodesis are commonly used in treatment of long biceps tendon (LHB) pathologies. The tenotomy can result in biceps distalization or cosmetic deformities. A novel loop Tenodesis Technique (LTD) could prevent a distalization of the biceps muscle without the risk of implant associated complications. The purpose of this study was to investigate the biomechanical aspects of the novel LTD compared to a standard tenotomy of the LHB. It has been hypothesized that the novel technique will show biomechanical superiority in terms of resistance and distalization.

Methods

Seven paired adult human cadaveric shoulder joints were assigned to one of the two study groups: Loop tenodesis (LTD); simple tenotomy (STT). In both groups load-to-failure testing was performed. The load-displacement curve was used to determine the maximum load (N), the degree of distalization of the LHB (mm) and the stiffness (N/mm). Additionally, the mode of failure was registered.

Results

The LTD group achieved a significantly higher ultimate load to failure (LTD: 50.5 ± 12.5 N vs. STT: 6.6 ± 3.9 N; p = 0.001). Significantly less distalization of the tendon could be detected for the LTD group (LTD: 8 ± 2.3 mm vs. STT: 22.4 ± 2.4 mm; p = 0.001). Stiffness was 7.4 ± 3.9 N/mm for the LTD group and 0.23 ± 0.16 N/mm for the STT group (p = 0.001). In all specimens of the LTD group a tendon rupture was found as mode of failure, while the STT group failed because of pulling out the LHB through the bicipital groove.

Conclusion

The novel loop Tenodesis Technique shows biomechanically higher stability as well as less distalization compared to a simple tenotomy of the long biceps tendon.

Biceps tenodesis versus tenotomy in isolated LHB lesions: a prospective randomized clinical trial

INTRODUCTION

Currently there exists no clear evidence concerning the surgical treatment of LHB lesions with either tenotomy or tenodesis. The aim of the study is therefore to evaluate elbow flexion and forearm supination force as well as the biceps muscle distalization according to both techniques in isolated LHB lesions.

METHODS

Consecutive patients aged 40-70 years with shoulder arthroscopies for isolated SLAP or biceps pulley lesions were prospectively randomized to arthroscopic suprapectoral intraosseous LHB tenodesis or tenotomy. Pre-, 6 and 12 months postoperatively, the SST, ASES, Constant-Murley and LHB scores were recorded. The elbow flexion force was measured in 10°/90° flexion, the supination force in neutral/pronation position. In addition, the maximum upper-arm circumference and its position relative to the radial epicondyle of the humerus were evaluated preoperatively and in follow-up.

RESULTS

20/22 patients (mean age 52.0 ± 8.5; range 36-63 years, 11 male) completed the follow-up. 9/20 were treated with LHB tenodesis (mean age 51.5 ± 9.5; range 37-63 years, 7 male) and 11/20 with tenotomy (mean age 52.8 ± 8.0; range 36-62 years, 4 male). The force measurements and scores showed no significant difference after 12 months. Tenodesis achieved a significant increase in force 6 months postoperatively compared to preoperatively. One tenodesis patient and three tenotomy patients showed a postoperative popeye-sign deformity.

CONCLUSION

This prospective randomized study comparing LHB tenodesis and tenotomy in isolated LHB lesions has shown no significant difference in elbow flexion and forearm supination force and clinical scores after 12 months. After LHB tenotomy, there was a non-significant trend for a higher rate of popeye-sign deformities of the upper arm and biceps muscle cramps.

Patient-determined outcomes after arthroscopic rotator cuff repair with and without biceps tenodesis utilizing the PITT technique

HYPOTHESIS AND BACKGROUND

The percutaneous intra-articular transtendon technique (PITT) is a simple, rapid, and low-cost method of performing a biceps tenodesis. Few studies exist that examine the patient-determined outcomes of this technique in general or in patients undergoing arthroscopic rotator cuff repair (RCR) with and without biceps tenodesis. We hypothesized that patients undergoing an isolated arthroscopic RCR would have equivalent outcomes to those undergoing RCRs with PITT biceps tenodesis.

METHODS

We compared preoperative, patient-determined outcomes scores on patients undergoing primary arthroscopic RCR with and without a PITT biceps tenodesis with postoperative scores at a minimum of 2 years. These scores included the Western Ontario Rotator Cuff score (WORC), American Shoulder and Elbow Surgeons score (ASES), Single Assessment Numeric Evaluation (SANE), Simple Shoulder Test (SST), and Shoulder Activity Level (SAL). Indication for a concomitant biceps tenodesis was a partial long head biceps tendon tear or biceps instability/subluxation.

RESULTS

A total of 153 patients underwent an isolated RCR and 131 patients underwent RCR with biceps tenodesis (RCRBT). Both groups had improvements in WORC, ASES, SANE, and SST (P < .0001) and deteriorations in the SAL (P ≤ .005). There was no difference in the change in outcome scores between the groups (RCRBT vs. RCR, respectively) for WORC (46 vs. 47; P = .85), ASES (46 vs. 47; P = .82), SANE (53 vs. 51; P = .35), SST (5.8 vs. 5.8; P = .93), and SAL (-0.9 vs. -1.4; P = .46). There was no difference between the groups in complications that required revision surgery (1.5% vs. 1.3%; P = .91).

CONCLUSIONS

Arthroscopic PITT RCRBT is safe and effective with equivalent patient-determined outcomes compared with patients undergoing RCR without biceps tenodesis.

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

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