Abstract
OBJECTIVE: We analyzed the clinical and functional results of patients with irreparable posterosuperior rotator cuff tears treated with arthroscopic-assisted latissimus dorsi transfer and the clinical relevance of the addition of partial repair of the remaining cuff to the transfer. METHODS: This was a prospective cohort study that included patients diagnosed with irreparable massive rotator cuff tears treated by arthroscopic-assisted latissimus dorsi transfer between 2015 and 2018. Demographic characteristics, clinical and functional outcomes (Constant-Murley (CS) score and subjective shoulder value (SSV)), and the incidence of complications were evaluated. Clinical outcomes were compared between patients treated with transfer alone and transfer with partial cuff repair. RESULTS: Fifteen patients were included, with an average follow-up of 37 ± 16 months. The median duration of symptoms before surgery was 66 weeks (24-208). A significant increase in forward elevation of 52° (p < 0.003) and abduction of 48° (p < 0.001) was obtained. The CS score increased by 48 points (p < 0.001), and the SSV changed from 29% preoperatively to 70% postoperatively (p < 0.001), with a significant decrease in the visual analog pain score from 7 to 1 (p < 0.001). In 10 patients, partial repair of the rotator cuff was also performed. No statistically significant differences were found in these patients compared with patients treated with transfer alone. Two patients presented complications, including transient sensitive neuropraxia of the axillary nerve and seroma, which were managed conservatively and did not affect the outcomes. CONCLUSION: Arthroscopic-assisted latissimus dorsi transfer is a safe technique that significantly improves clinical and functional outcomes in selected patients. Longer follow-up and comparison with other treatment options are needed to confirm these excellent results in this group of difficult-to-treat patients. LEVEL OF EVIDENCE IV: Nil.
