Rotator cuff tear is a common disease in clinical practice and a goal of rehabilitation is to return the surgical extremity to its original strength. The purpose of this study was to determine the shoulder strength in patients who had undergone rotator cuff repair and acromioplasty surgery. Twenty-three male patients with average age 60.7 were tested bilaterally on the Kin-Corn 500H isokinetic dynamometer. Extemal rotation, internal rotation and flexion were tested in a velosity of 60 /sec. The results were compared in two groups devided in according to the tear size smaller or larger than 3 cm.The result showed that the large tear group had smaller strength than the small tear group especially in external and interal rotation which were statistically significant. The strength ratio of the operated and nonoperated shoulders showed 66%, 81% and 87% in external rotation, internal rotation and flexion. We also compared the strength ratio of external and internal rotation and it was 74% in nonoperated shoulders and 58% in operated shoulders. The result showed that the operated shoulder strength did not return to the level of the nonoperated and the tear size was related to the recovery. This finding may add information in estimating the prognosis and postsurgical rehabilitation.
