A biomechanical comparison of subscapularis repair techniques in total shoulder arthroplasty: lesser tuberosity osteotomy versus subscapularis peel

Abstract

No significant differences were found in repair gapping, fatigue failure, and load to failure in comparing the SP and LTO repairs. However, the SP repair demonstrated significantly less variability in repair gapping. These findings suggest that initial fixation biomechanical properties between the 2 constructs are similar in vitro.
