Advantages and Disadvantages

Advantages

Preservation of healthy native cartilage

Preservation of native biomechanics including neck-shaft angle, center of rotation, and humeral offset

Minimal bone resection

Decreased blood loss and operative time compared with stemmed implants

Decreased rate of periprosthetic fracture compared with stemmed implants

Decreased risk of implant wear and implant loosening compared with implants with glenoid components

Low revision rate

Easy conversion to another implant design as needed

Disadvantages

Does not treat concomitant pathology and may have worse outcomes when performed in setting of concomitant pathology
