Supracapsular reconstruction (SCR) combined with transposition of the biceps long head biceps tendon (LHBT) is an approach designed to meet the severe challenges posed by massive rotator cuff tears (MIRCT).
Although LHBT transposition has been adopted, its exact impact remains to be clearly elucidated.
There are gaps in our knowledge of the outcomes produced by this technique, and thus further research is needed to reveal its potential benefits and limitations.
We conducted a methodical search of electronic databases to identify relevant literature based on inclusion and exclusion criteria. We first conducted a systematic review of the main findings and conclusions of the biomechanical studies. Subsequently, we conducted a comprehensive meta-analysis of the clinical outcomes of the included studies.
Biomechanical studies have reported that after performing LHBT transposition in MIRCT, there was a comprehensive improvement in subacromial contact pressure and a prevention of proximal humeral migration, without any resultant limitation in range of motion. The meta-analysis of LHBT transposition outcomes has encompassed five clinical studies demonstrated that, compared to other surgical methods for MIRCTs, LHBT transposition exhibited significant advantages in enhancing patients’ ROM (forward flexion, mean difference [MD] = 6.54, 95% confidence interval [CI]: 3.00-8.08, external rotation [MD = 5.15, 95%CI: 1.59-8.17], acromiohumeral distance [AHD] [MD = 0.90, 95%CI: 0.21 to 1.59], and reducing the risk of retear [odds ratio = 0.27, 95%CI: 0.15-0.48]). There were no discernible differences between the two groups of patients in terms of American Shoulder and Elbow Surgeons scores, visual analogue scale scores, and University of California, Los Angeles scores.
In summary, the utilization of LHBT transposition in SCR proved to be a dependable and cost-effective approach for addressing MIRCTs. This technique demonstrated favorable results not only in terms of biomechanical factors but also in clinical outcomes. It exhibited comparable efficacy to conventional SCR and other established techniques, while presenting notable improvements in ROM, AHD, and a reduced incidence of retear. Nevertheless, it is essential to emphasize the necessity for additional high-quality randomized controlled trials focusing on the long-term effects of SCR with LHBT transposition to further evaluate its efficacy.
Future high-quality research of SCR using LHBT transposition for MIRCTs is necessary.
