[Purpose] The purpose of this study is to evaluate the results of the operative treatment for rotator cuff tears using the analysis of the correlation between the size of the tear and pain before and after surgery.<BR>[Materials and Methods] We examined two hundred shoulders with rotator cuff tears after surgery. The subjects consisted of 127 males and 73 females aged aged from 20 to 77 years (average age: 53.7±8.8SD years). Based on the intra-operativeassement of the tear size, the tears were classified as follows.<BR>Group I: macroscopic incomplete rotator cuff tears, which included either partial-thickness tears or arthrographic complete tears. Group S: full-thickness tears of which the defects were less then 1 cm. Group M: the defects were 1 to 3 cm. Group L: the defects were greater than 3 cm with retention of tendon mobility. Group G: the defects were greater than 3 cm with loss of tendon mobility. We evaluated pain according to the shoulder evaluation sheet of the Japanese Orthopaedic Association (JOA)score pre-and post-operatively.<BR>[Results] Ther e were statistically significant differences between Group I and Group M before surgery (p<0.05), Group I and Groups S, M, and L after surgery (3 months: p<0.0005,6 months: p<0.01,12months: p<0.05). Furthermore, we found statistical correlations between the pre-operative J OA pain scores and the post-operative ones.<BR>[Conclusion] Patients with intraoperative incomplete tears were likely to have more pain before and after surgery than the other groups. Patients with severe pre-operative pain often had residual pain. It is very important to reduce pre-operative pain and muscle spasms for the success of operative treatment.
