摘要Irreparable rotator cuff tears ( IRCTs ), due to fatty inifltration and tendon retraction of the rotator cuff, is a challenge for orthropaedic surgeons, especially surgeons of sports medicine. It also has a huge influence on shoulder range of motion ( ROM ) loss and life quality. Currently, the treatment strategies of IRCTs still remain controversial, including conservative procedures, arthroscopic acromioplasty, partial repair, rotator cuff reconstruction and shoulder preserving athroplasty. With the popularity of new biomaterial application, there is another option to IRCTs surgery. However, healing effects of the new material with bone and tendon, mechanical strength, rotator cuff functions are still in need to be explored.
