The implantation was done using an angled surgical approach so the head is left in place.

The implant is designed as an inlay to match the surrounding anatomy and the stability of an inlaid implant should minimize or eliminate any overstuffing or rocking of the implant.

Arthrosurface co-founder and designer Steve Ek said their goal when designing the new GRS glenoid was to address the issues and allow surgeons to perform a total resurfacing without removing the head.
