Osteochondral autograft transfer (OAT) allows for the treatment of focal chondral lesions of the femoral condyles. Patients undergoing OAT have been shown to have the greatest rate and quickest return to sport of any cartilage-restoration procedure. Disadvantages encountered with the OAT procedure include limited donor sources, small treatable lesion size, and donor-site morbidity. Here, we describe our preferred technique of open OAT with donor-site back-filling using precut fresh osteochondral allograft plugs and micronized extracellular cartilage augmentation. Advantages to this technique include single-stage transfer of living autologous osteochondral grafts allowing for early ambulation, predictable return to sport, enhanced long-term graft survival, and decreased donor-site morbidity secondary to fresh osteochondral allograft back-fill.
