| Outline of Final Research Achievements |
Eight cadaveric shoulders were tested in a custom shoulder testing system. Glenohumeral translation, translation, subacromial contact pressure, and glenohumeral range of motion, were compared among 5 conditions:
1)intact rotator cuff; 2)repairable non degenerative rotator cuff tear; 3)repairable degenerative rotator cuff tear; 4)primary repair of degenerative rotator cuff tear; And 5)SCR + primary repair of degenerative cuff tear.
SCR augmentation of degenerative cuff tear repair (defined as 25% loss of thickness at tendon edge) improves superior stability without restricting range of motion.

| Academic Significance and Societal Importance of the Research Achievements |
腱の変性が強い腱板断裂に対する腱板修復術の治療成績を安定させることは容易ではないと考えられているが、本研究において腱板修復術に上方関節包再建術を追加することにより、腱板修復術を単独で行う場合よりも肩関節上方安定性が改善するという結果が得られれば、腱板修復術の治療成績を向上させる可能性が高く、大変意義深いと考える。
