Biceps Smash Technique: Biceps Tendon Autograft Augmentation for Arthroscopic Rotator Cuff Reconstruction

Reinforcements and augmentations with the long head of the biceps tendon in shoulder surgery: a narrative review

The long head of the biceps tendon (LHBT) has recently emerged as a therapeutic option for various shoulder pathologies. Synthetic materials and allografts have not shown sufficient resistance or favorable outcomes to restore rotator cuff native tissue properties, leading to consideration of using LHBT as biological augmentation. LHBT mimics adjacent structures, such as the rotator cuff, is easily accessible during surgery, and is a good source of live autologous cells for regenerative augmentation in rotator cuff repair, as a superior capsular reconstruction in irreparable cuff tears, in subscapularis augmentation in shoulder replacement and as a stabilizer in anterior shoulder instability. This narrative review aims to collect, synthesize and critically evaluate the literature on the use of the LHBT and its current applications in the field of shoulder surgery, improving the understanding of the terminology and consolidating the concepts related to the various procedures in shoulder surgery.

Augmentation Techniques for Rotator Cuff Repairs

» Despite enhanced understanding of risk factors for failure and enhanced surgical repair techniques, the risk for failure of the rotator cuff to heal after surgery is still substantial.» A patient-specific approach to augmentation is essential, with decisions based on tear and patient characteristics.» Augmentation can improve repair strength and promote cellular infiltration, which collectively contribute to better healing outcomes.» Augmentation strategies may improve outcomes in rotator cuff repairs, particularly in high-risk cases; however, there is a lack of consensus among surgeons on the most effective strategies for each scenario.

The Evolution of Arthroscopic Shoulder Surgery: Current Trends and Future Perspectives

Arthroscopic shoulder surgery has undergone significant advancements over the past decades, transitioning from a primarily diagnostic tool to a comprehensive therapeutic approach. Technological innovations and refined surgical techniques have expanded the indications for arthroscopy, allowing minimally invasive management of shoulder instability and rotator cuff pathology. Methods: This narrative review explores the historical evolution, current trends, and future perspectives in arthroscopic shoulder surgery. Results: Key advancements in shoulder instability management include the evolution of the arthroscopic Bankart repair, the introduction of the remplissage technique for Hill-Sachs lesions, and the development of arthroscopic Latarjet procedures. Additionally, novel techniques such as Dynamic Anterior Stabilization (DAS) and bone block procedures have emerged as promising solutions for complex instability cases. In rotator cuff repair, innovations such as the suture-bridge double-row technique, superior capsular reconstruction (SCR), and biological augmentation strategies, including dermal allografts and bioinductive patches, have contributed to improving tendon healing and functional outcomes. The role of biologic augmentation, including biceps tendon autografts and subacromial bursa augmentation, is also gaining traction in enhancing repair durability. Conclusions: As arthroscopic techniques continue to evolve, the integration of biologic solutions and patient-specific surgical planning will likely define the future of shoulder surgery. This review provides a comprehensive assessment of current state-of-the-art techniques and discusses their clinical implications, with a focus on optimizing patient outcomes and minimizing surgical failure rates.

Reduced retear rates yet similar clinical outcomes following arthroscopic partial repair of large and massive irreparable rotator cuff tears with biceps augmentation compared to repairs without biceps augmentation: A systematic review and meta-analysis

PURPOSE

To compare the clinical outcomes between arthroscopic partial rotator cuff repair with biceps augmentation (BA) and partial repair (PR) without BA.

METHODS

This systematic review included studies comparing outcomes of arthroscopic repair for large to massive irreparable rotator cuff tears with and without the BA. The focus was on postoperative clinical results and retear rates. Mean differences were used to express continuous outcomes, while odds ratios (ORs) were employed for dichotomous outcomes.

RESULTS

Ten studies (733 shoulders, all level 3 evidence) were included. The BA group showed a significant reduction in retear rates (OR = 0.40, 95% confidence interval [CI]: 0.20-0.77, P = 0.007) and comparable postoperative outcomes across various measures: American Shoulder and Elbow Surgeons (ASES) score, visual analogue scale for pain, University of California-Los Angeles shoulder score, active forward flexion motion and active external rotation at the arm-at-side position compared to the PR group. Subgroup analysis of two BA techniques-rerouting and supplementation following supraglenoid tenotomy-showed no significant differences in ASES score for either technique versus PR. However, rerouting significantly lowered retear rates (OR = 0.21, 95% CI: 0.12-0.36, p < 0.001), while supplementation showed similar retear rates to PR (OR = 0.87, 95% CI: 0.37-2.02, n.s.).

CONCLUSION

Arthroscopic partial rotator cuff repair with BA for large to massive irreparable rotator cuff tears is a reliable technique, resulting in improved postoperative outcomes. BA using supplementation following supraglenoid tenotomy showed similar clinical outcomes and range of motion but with lower retear rates compared to the PR group.

LEVEL OF EVIDENCE

Level III.

Mini-open transosseous repair with bursal augmentation improves outcomes in massive rotator cuff tears

Treatment of Massive rotator cuff tears (MRCT) is difficult, with high rates of retears. Using biological augmentation in the form of the highly vascular subacromial bursa, was used to improve tendon healing. This work aimed to evaluate the results of arthroscopic guided mini-open transosseous repair with bursal augmentation in the treatment of MRCTs in a five-step approach. Forty-eight patients, with a mean age of 63.15 years, were treated with this technique. The patients were evaluated with the constant, UCLA and VAS scores. Plain X-rays were performed to evaluate the CSA and MRI was done to confirm the diagnosis of MRCT and determine the degree of fatty degeneration. Ultrasound was done at 1 year post-operative to determine any retears. The mean follow-up period was 29 months ± 4.95. The Constant and UCLA mean scores improved from (52.52) to (89) and (13.2) to (30.5) respectively (p < 0.0001). The post-operative active flexion and abduction improved from a mean of (112° to 170°) and (136.2° to 167°) respectively, while ER improved from (62.8° to 70°) with their p values (p < 0.0001). Pain improved from a mean VAS of (5.85) to (0.5) (p < 0.0001). No deterioration of function was noted throughout the follow-up period, and no retears occurred on post-operative ultrasound evaluation. Mini-open transosseous repair with bursal augmentation in the treatment of MRCT is an effective and low-cost method that achieves satisfactory results with no retears.

Does timing influence rehabilitation outcomes in arthroscopic rotator cuff repair with biceps rerouting? a prospective randomized study

BACKGROUND

Arthroscopic rotator cuff repair with biceps rerouting (ABR) has emerged as a reliable option for treating large posterosuperior rotator cuff tears (RCTs). This study aims to compare functional and structural outcomes of early vs. delayed motion rehabilitation protocols following ABR.

METHODS

A total of 101 patients with semirigid, large, posterosuperior RCTs undergoing ABR were randomized into 2 groups: group I (early motion) with 53 patients (34 females, 19 males) and group II (delayed motion) with 48 patients (31 females, 17 males). In group I, the mean age was 63.9 years (range, 46-79), and in group II, it was 65.4 years (range, 43-78). The mean follow-up periods for group I and group II were 16.2 and 15.5 months, respectively. Preoperative and postoperative assessments were conducted at 3, 6, and 12 months, with structural integrity assessed with magnetic resonance imaging at a minimum follow-up of 12 months. Statistical analyses were performed to compare outcomes between the 2 groups.

RESULTS

Both groups demonstrated significant improvements in visual analog scale score (group I: 4.0-1.6, group II: 3.7-1.4, P = .501), University of California-Los Angeles shoulder score (group I: 21.5-31.4, group II: 22.4-30.6, P = .331), and acromiohumeral interval (group I: 8.2 mm-9.1 mm, group II: 8.6 mm-9.5 mm, P = .412), with no statistically or clinically meaningful differences. Active range of movements (ROM) were not significantly different between groups, except for active forward flexion at 3 months (group I: 140.1°, group II: 119.2°, P = .006), that was not shown to be translated clinically into differences in function or healing between the groups in this study. Notably, retear rates were similar between groups (group I: 22.6%, group II: 20.8%, P = .826).

CONCLUSION

This study's findings reveal no clinically discernible differences in active range of motion at 1-year follow-up between patients who underwent ABR for semirigid, large, posterosuperior RCTs and were assigned to either early or delayed motion protocols. Notably, the early motion group demonstrated a plateau in maximum range of movement improvement as early as 3 months postsurgery. Based on these results, implementing an early motion protocol is recommended as an effective approach in the postoperative rehabilitation following ABR.

Biologic augmentation of rotator cuff repair with microfragmented autologous subacromial bursal tissue enveloped in a patch of compressed autologous long head of biceps tendon tissue: the Bio-Ravioli technique

Background

Rotator cuff repair is one of the most frequently performed procedures in orthopedic surgery. However, considering the limited healing potential of rotator cuff tendons, several augmentation strategies have evolved to enhance tendon healing. The purpose of this article was to present a new surgical technique called Bio-Ravioli.

Methods

Patients with repairable full-thickness posterosuperior rotator cuff tear and a moderate-to-high risk of healing failure were chosen as candidates for the Bio-Ravioli procedure. It is a biologic augmentation strategy to increase healing potential of arthroscopic rotator cuff repair by use of a biologic graft fixed at the bone-tendon interface. The Bio-Ravioli consists of microfragmented autologous subacromial bursal tissue enveloped in a patch of compressed autologous long head of biceps tendon tissue. The rotator cuff is then repaired to the bone and over the graft using a transosseus equivalent configuration.

Conclusion

The Bio-Ravioli technique represents an easy and reliable way to increase the healing potential at the bone-tendon interface by using autologous mesenchymal stem cells from different sources: subacromial bursa and long head of the biceps tendon.

Patch Augmentation in Arthroscopic Rotator Cuff Surgery-Review of Current Evidence and Newest Trends

Background: Rotator cuff tears are a common and debilitating condition requiring surgical intervention. Arthroscopic rotator cuff repair is essential for restoring shoulder function and alleviating pain. Tear classification by size and tendon retraction, along with the grade for fatty infiltration, influence postoperative outcomes, with large tears and higher fatty infiltration grades linked to higher retear rates. Managing complex tears is challenging, with failure rates ranging from 20 to 94%. Patch augmentation has emerged as a promising strategy, using biological or synthetic materials to reinforce tendon repairs, enhancing structural integrity and reducing retear risk. Methods: A review of the recent literature from January 2018 to March 2024 was conducted using PubMed/MEDLINE, Embase, and Web of Science. Keywords included "rotator cuff tear", "rotator cuff augmentation", "rotator cuff patch", "tendon augmentation", "massive rotator cuff tear", "patch augmentation", and "grafts". Relevant articles were selected based on their abstracts for a comprehensive review. Results: Initial methods used autograft tissues, but advances in biomaterials have led to standardized, biocompatible synthetic patches. Studies show reduced retear rates with patch augmentation, ranging from 17 to 45%. Conclusions: Patch augmentation reduces the retear rates and improves tendon repair, but complications like immune responses and infections persist. Cost-effectiveness analyses indicate that while initial costs are higher, long-term savings from reduced rehabilitation, revision surgeries, and increased productivity can make patch augmentation economically beneficial.

Biceps tendon autograft augmentation for rotator cuff and instability procedures: a narrative review

Rotator cuff tears (RCT) and instability are the most common surgically treated shoulder pathologies. The concept of augmentation using the long head of the biceps tendon (LHBT) autograft was created to improve the results of surgical treatment of these pathologies, especially in cases of chronic and massive injuries. The popularity of using the LHBT for augmentation is evidenced by the significant number of publications on this topic published in the last 3 years; however, only one systematic review has been published regarding only LHBT augmentation for massive RCTs. Several studies comparing partial repair with partial repair and additional LHBT augmentation for RCT showed superior clinical outcomes and lower re-tear rates when LHBT augmentation was performed. There is a rising popularity of using LHBT as an autograft to perform superior capsule reconstruction (SCR) in case of irreparable rotator cuff tears. In recent years, shoulder stabilization by arthroscopic Bankart repair with biceps augmentation has been promoted with very promising short-term results. The evidence provided by studies appears to be sufficient to recommend the use of LHBT for augmentation whenever necessary; however, larger studies with long-term follow-up are needed.

Anterior Labral Reconstruction With Biceps Autograft for Anterior Shoulder Instability

Shoulder instability is a common problem, with current research focused on understanding the implications of humeral and glenoid bone loss. Soft tissue injury, including damage to the anterior labrum, deformity of the capsule, and disruption of the inferior glenohumeral ligament, also contributes to the pathology of shoulder dislocation with implications for recurrent instability. Anatomic placement of the labral tissue and restoration of capsular tension are essential components of successful arthroscopic Bankart repair (ABR). Patients who meet criteria for ABR with a diminutive, ruptured, or absent anterior labrum at the time of arthroscopic stabilization present a significant challenge to repair. In this Technical Note, we demonstrate a technique using biceps autograft to reconstruct the anterior labrum.

Editorial Commentary: Shoulder Long Head of the Biceps Tendon Transposition Without Tenotomy May Be a Beneficial Augment for Massive Rotator Cuff Tear Repair

Although many surgeons discard the long head of the biceps (LHB) tendon during arthroscopic rotator cuff repairs, several authors have argued that the LHB tendon may serve as a biologic and structural augment for massive repairs. There are multiple benefits of incorporating the LHB tendon autograft in difficult-to-repair massive rotator cuff tears. First, by maintaining the glenoid origin, the tendon likely retains a significant native blood supply, as well as tenocytes, which may support the healing process. In addition, there are several biomechanical benefits. The LHB may act as a dynamic humeral head depressor since it is still attached to the muscular unit distally. The tendon could also serve as a convergence post, while proving robust tissue for the repair. Also, the LHB tendon may decrease undue tension on the repair, bringing us closer to a tension-free repair. Finally, this may be a cost-conscious technique. One concern, requiring additional investigation, is that some surgeons believe the LHB may be a pain generator in patients with rotator cuff tears. One surgeon's trash is another surgeon's treasure.
