Osteochondral Autograft Transplantation Surgery (OATS)
In this procedure, the surgeon harvests a bone graft (a section of bone from an unaffected area of the joint that has a cartilage covering) and transplants it into the damaged area. The graft is removed from a location that does not have to bear a significant amount of weight, to allow that region to heal.
More than one graft can be transplanted based on the patient's needs. This procedure can be either minimally invasive or open (requiring large incisions) dependent on the amount of grafts needed.
