The Role of Inlay and Inset Glenoid Implants in Anatomic Total Shoulder Arthroplasty.

Anatomic total shoulder arthroplasty is an established treatment for degenerative conditions involving the shoulder. One well-described complication of total shoulder arthroplasty is glenoid loosening, especially in younger and more active patients. As a result, several surgeons recommend against activities that may put patients at risk of implant failure after shoulder arthroplasty. Newer inlay and inset glenoid implants may have a role in treating arthritis in younger patients and may allow them to return to sports and high-impact activities, including weightlifting. These glenoid implants may also play a role in treating patients with notable glenoid deformity. However, more information is needed regarding their long-term outcomes.
