Biologic Resurfacing of the Glenoid Using a Meniscal Allograft

Biologic resurfacing of the glenoid is a treatment alternative for young patients who develop rapid and aggressive destruction of glenoid. In 2001, a technique was developed to allow secure fixation of a meniscal allograft to the glenoid in combination with hemi-arthroplasty replacement of the humeral head. The authors have modified this technique by addressing posterior wear factors, as well as circumferential covering of the glenoid perimeter. The meniscal horns are sutured together to fashion the allograft in an ovoid shape. The meniscus closely matches the circumference of the glenoid and therefore 180 degrees coverage of the glenoid rim is achieved. In addition, the wedge shape of the meniscus may enhance comfort and stability.
