There are various known methods for arthroscopic rotator cuff repair. The purpose of this retrospective study is to report on the clinical results and anatomical results of UU repair surgery, which is a new repair method. MATERIALS AND METHODS: We enrolled 156 patients (88 men and 68 women) who underwent UU repair for rotator cuff tears from January 2009 to May 2010 in our hospital. Their average age was 55 years old (range: 38~75 years old) and the average follow-up period was 12 months (range: 6~23 months). For determining the results, we evaluated the VAS for pain, the daily living index (ADL) in the ASES scores, the UCLA and KSS scores, and all these tests were conducted at the first hospital visit and 6 months and 1 year after surgery and at the final follow-up. During the follow-up period, MRI was performed 3 and 6 months after surgery only in the patients who consented to MRI scans to confirm the presence of re-rupture.
The average scores of the VAS as a pain indicator decreased from 7.0 before surgery to 2.7 after surgery (p<0.05). The UCLA and KSS scores increased from 22.2 to 32.5 and from 83.7 to 91.5, and the changes was significant (p<0.05). For the active joint range of motion, the average forward flexion was improved from 125 to 175 degrees, the average lateral external rotation was improved from 38 to 58 degrees, and the average abduction was improved from 104 to 169 degrees. Out of a total of 156 patients, re-rupture was observed in 4 cases (3%) of 117 cases (75%) for which MRI was performed (with consent) between 3 and 6 months after surgery.
UU repair surgery as arthroscopic repair of rotator cuff tear is a good repair method that shows excellent clinical results and a low re-rupture rate.
