We performed arthroscopic rotator cuff repair (ARCR) with converting to a full-thickness tear for partial thickness rotator cuff tear (PRCT) grade 3 in Ellmans classification. The purpose of this study was to evaluate the clinical results of ARCR for PRCT. We retrospectively studied 38 patients (38 shoulders) who had received ARCR for PRCT which is classified into grade 3 in Ellmans classification and were followed up for more than 6 months. The patients were 19 males and 19 females. The mean age at operation was 63 years old (range, 36-79). The mean postoperative follow-up period was 14 months (range, 6-26). The clinical results were assessed using JOA scores and MRI by Sugayas and Goutalliers classification.Tear size was <1cm tear in 15 shoulders, 1-3cm in 22 shoulders, and 3-5cm in 1 shoulder. The mean JOA total score was significantly improved from 65 points to 94 points postoperatively. The mean JOA pain score was significantly improved from 8 to 28, function score from 14 to 19, and ROM score from 24 to 27, respectively. Postoperative MRIs showed 2 type-3 shoulders in Sugayas classification.The selection of surgical methods for PRCT is still controversial. In this study, the clinical results of ARCR with converting to a full-thickness tear for PRCT grade 3 was mostly satisfactory. But further long term follow up is necessary.
