Biceps-incorporating rotator cuff repair with footprint medialization in large-to-massive rotator cuff tears

Purpose In large-to-massive rotator cuff tears (MRCTs), incorporating the long head of the biceps tendon (LHBT) with arthroscopic partial rotator cuff and margin convergence can improve clinical outcomes and preserve the acromio-humeral interval (AHI) during mid-term follow-up. The purpose of this study was to evaluate mid-term clinical and radiological outcomes of arthroscopic biceps-incorporating rotator cuff repair with partial release of the LHBT and footprint medialization through the Neviaser portal in MRCTs. Methods This study enrolled 107 patients (38 males and 69 females, mean age: 64.9 +/- 8.6 years) with MRCTs. A novel arthroscopic biceps-incorporating repair was performed by footprint medialization, with a partially released biceps tendon covering central defects. Clinical outcomes such as pain VAS, KSS, ASES, UCLA, SST and CS scores and ROM were evaluated at a mean follow-up time of 35 months (range 12-132 months). Serial radiographs with a mean postoperative MRI follow-up duration of 33 months were used to evaluate AHI, tendon integrity, fatty infiltration (FI) and muscle hypotrophy. Results Postoperative pain VAS, KSS, ASES, UCLA, SST, and CS scores and ROM (except external rotation) were improved significantly. AHI also improved significantly from 8.6 to 9.3 mm. According to Sugaya's classification, type I, II, III, IV, or V healing status was found in 30 (28.0%), 29 (27.1%), 26 (24.3%), 14 (13.1%), and 8 (7.5%) patients, respectively. The retear rate was 22 (20.6%). Conclusions Novel biceps-incorporating cuff repair with footprint medialization yielded satisfactory outcomes in MRCT patients at the 3-year follow-up. A partially released, repaired biceps tendon provided superior stability with preserved AHI similar to that of anterior cable reconstruction.

Automated summary

This study evaluated the mid-term clinical and radiological outcomes of arthroscopic biceps-incorporating rotator cuff repair with partial release of the long head of the biceps tendon (LHBT) and footprint medialization. The results showed satisfactory improvements in pain scores, shoulder function scores, and range of motion. The tendon integrity and acromio-humeral interval were also preserved.
