[Progress on improving tendon-to-bone healing for the enthesis of rotator cuff]

Rotator cuff repair is a common treatment for rotator cuff tear, which could effectively relieve shoulder pain and improve shoulder movement, and the incidence of rotator cuff retear after rotator cuff repair is still high. The main reason is poor tendon-bone healing in rotator cuff enthesis after rotator cuff repair and could not recover the original histological structure and biomechanical properties. Therefore, the key to solve the problem is how to effectively improve the healing of tendon bone at the end of rotator cuff. With the in-depth study of rotator cuff enthesis, various treatments have made great progress on improving tendon to bone healing of rotator cuff. Our study will discuss the researchprogress on tendon to bone healing of rotator cuff in recent years from three following aspects to provide some guidance for the clinical treatment of rotator cuff tear:the factors affecting the tendon to bone healing of rotator cuff, the recovery of tendon to bone interface promoting the tendon to bone healing of rotator cuff and the application of tissue engineering in tendon to bone healing.
