Rotator Cuff Repair Using Coracoacromial Ligament Autograft for Supraspinatus Footprint Augmentation.

Abstract

Failure of rotator cuff repair can be a disastrous clinical outcome. Although failure is a multifactorial issue, recent interest has piqued in understanding the biology of the insertional components of the supraspinatus and infraspinatus at the footprint. When the torn tendon is of poor quality, especially if it is diminutive or thin, rotator cuff repair augmentation should be considered to aid in long-term healing. Various allograft options have been described in the past, and more recently, xenografts and synthetics have become more commonly used. The use of autografts in the treatment of insertional footprint deficiency has great potential; however, few grafts have been described. This study describes the surgical technique for footprint augmentation in arthroscopic supraspinatus repair using harvested autologous coracoacromial ligament tissue.
