Biological glenoid resurfacing - a cadaver study

Feasibility of an osteochondral allograft for biologic glenoid resurfacing

The authors suggest that isolated chondral defects, chondrolysis, osteoarthritis, post-traumatic arthritis, and instability arthropathy in the young active patient may be an indication for osteochondral allograft transplantation to the glenoid.

They studied 16 to determine the dimensions of a graft that could be inserted. They found that shallower graft depths allowed larger graft diameters. Most glenoids supported center-based grafts of 16 to 20 mm in diameter at a depth of 4 mm, covering an average of 51.9% of the glenoid. 

While this is an innovative approach, it is unclear whether there are many cases of unipolar, glenoid-only arthritis of the shoulder and whether such a procedure would be technically feasible or clinically effective.
