Clinical Outcomes of Arthroscopic Revision Rotator Cuff Repair.

AIMS: Multiple studies have shown excellent clinical results in primary rotator cuff repairs; however, not much evidence is available in the literature on the outcomes of arthroscopic revision rotator cuff repairs. The purpose of this study was to report a cohort of patients who underwent revision arthroscopic rotator cuff repair and identify factors that may influence its outcomes.

METHODS: We examined a cohort of 62 patients which underwent revision arthroscopic rotator cuff repair in a single UK institution with a minimum of 24 months follow-up. Active shoulder movements including forward flexion, abduction and external rotation were evaluated, as well as Oxford Shoulder Score (OSS). Further subgroup analysis was performed looking of the effects of age, size of tear, obesity and diabetes mellitus had on clinical outcomes.

RESULTS: 59 patients were available for final review. 39 male and 23 were female. The mean age was 64 years. Overall, significant improvements were seen in terms of OSS ( p  < 0.05), active forward flexion ( p  < 0.05), active abduction ( p  < 0.05) and active external rotation ( p  < 0.05). Our study showed that a significant proportion of patients undergoing arthroscopic revision rotator cuff repair achieve good outcomes. Repairing small- and medium-size tears was successful, diabetics had no post-operative improvements, obese patients achieved significant improvement in range of movement and age was not a predictor of surgical success.

CONCLUSION: Overall, arthroscopic revision surgery is a successful option; however, appropriate patient selection and counselling is paramount.
