Brief Summary:
The purpose of this study is to conduct a prospective randomized controlled trial to compare the effects of arthroscopic debridement and repair for Ellman grade II bursal-side partial-thickness rotator cuff tears.The hypothesis was that there would be no difference in prognosis between arthroscopic debridement and repair.
Detailed Description:
This was a single-center, prospective, double-blinded, randomized controlled trial, comparing arthroscopic debridement and arthroscopic repair for Ellman grade II BPTRCTs. Participants were recruited from September 2017 to April 2019. Before initiating the trial, an investigator who was not involved in the study generated a computer-generated randomization list (block length 10, ratio 1:1). Allocation concealment was achieved by using opaque, sealed, sequentially numbered envelopes containing details of group assignment. Assignment occurred after baseline information was recorded. Whereas participants and surgeons were aware of the group assignments, the outcome assessors and data analysts were remained blinded during the study period. Operations were performed by the same team of sports medicine surgeons under general anesthesia. For the debridement group, only stump refreshing and surrounding soft tissue cleaning were performed. For the repair group, partial tears were converted into full-thickness tears and sutured. The sample size calculation was based on data from previous studies, where the difference in Constant-Murray Shoulder (CMS) score between patients with arthroscopic repair and arthroscopic debridement was 8.81 points (93.90 vs. 85.09) with standard deviations of 5.4 and 21. Accepting an α risk of 0.05 and a β risk of 0.2 in a bilateral contrast, the minimum sample size required for each group was 35. To compensate for an estimated 15% loss to follow up, at least 82 patients would be included.
