Abstract
[Abstract] Superior Capsule Reconstruction (SCR) has been described as an effective treatment modality in patients with massive or irreparable rotator cuff tears in the shoulder. The concept and the principle behind fascia lata autograft SCR were developed and refined by Teruhisa Mihata, MD, PhD to treat patients with massive irreparable rotator cuff tear. The procedure is designed to reestablish the concavity compression in the shoulder and enable deltoid function as well as improving dysfunctional rotator cuff force couples. Clinical outcome studies for fascia lata autograft SCR have demonstrated consistent pain relief, patient satisfaction, and recovery of lost shoulder function. While fascia lata autograft SCR continues to gain in popularity as a treatment option, debate still exists as to the optimal fixation methods, graft choice, and concomitant procedures. In this manuscript, the biomechanics of the shoulder and the biomechanical studies that were performed to refine the fascia lata SCR to treat massive or irreparable rotator cuff tears will be detailed and explained.
