Cartilage Restoration (OATS, Microfracture, allograft transplantation)
Surgical procedures performed to treat articular cartilage defects of the knee. The OATS procedure consists of grafting a section of articular cartilage from a non-weight bearing area to the defect of concern. The cartilage graft is removed with the underlying bone. The recipient site is prepared by drilling a socket that will accommodate the graft. The graft is then inserted into the prepared site.

Microfracture Technique
The microfracture technique stimulates cartilage growth by drilling multiple, tiny holes in the defect. This allows stem cells and bone marrow elements to migrate to the bone surface and promote cartilage repair.
An allograft transplant utilizes an articular cartilage and bone graft similar to the OATS procedure, but the graft is harvested from a cadaver donor.
