Abstract
Glenoid component loosening is a common cause of failed total shoulder arthroplasty. Many different treatment options exist for the management of a symptomatic loose polyethylene glenoid component, ranging from component removal to revision arthroplasty. Arthroscopic removal and conversion to hemiarthroplasty provides a minimally invasive management option that avoids takedown of the subscapularis and allows for humeral prosthesis retention. Frequently, however, osteolysis is encountered concomitantly leading to cavitary glenoid bone deficits at the time of glenoid implant removal, limiting both immediate and future treatment options. The purpose of this Technical Note is to describe in detail an all-arthroscopic technique for removal of a loose polyethylene glenoid component with subsequent bone grafting of a contained glenoid bone defect, and insertion of a human dermal allograft patch.
