Low healing rates and moderate functional outcome after arthroscopic superior capsular reconstruction using a porcine xenograft.

Purpose: In the absence of arthropathy, symptomatic massive irreparable rotator cuff tears contribute to a therapeutic challenge for orthopedic surgeons. The concept of superior capsular reconstruction (SCR) was introduced as an option for these challenging cases. The purposes of this study were to evaluate the clinical outcome scores when using a decellularized porcine xenograft and to evaluate the graft healing and incorporation.
