The biomechanics of subscapularis repair in reverse shoulder arthroplasty: The effect of lateralization and insertion site

Functional outcomes of subscapularis (SSc) repair following reverse shoulder arthroplasty (RSA) remains controversial. SSc repair in combination with glenosphere lateralization was reported to yield worse clinical outcomes compared with the non‐lateralized glenosphere. The aim of this biomechanical study was to investigate how glenosphere lateralization and different re‐insertion sites can affect the biomechanics of the SSc after RSA. Nine...
