The authors treated 52 patients with osteochondral autografts, with an ordinarily follow-up of 37 months. At the latest follow-up, improved knee chore was observed in 92% of the patients.

The authors conducted a retrospective bone up on comparing 48 patients receiving osteochondral auto- transplant transplantation mosaicplasty to 48 patients receiving microfracture for full-thickness cartilage defects of the femoral condyle or trochlea. They concluded that osteochondral autograft transplantation improves clinical outcomes when compared with preoperative conditions and may allow bring to pastime as untimely as 6 months after the procedure. Furthermore, osteochondral autografting is more befitting as a remedy for lesions that are smaller than 2 cm.

The authors concluded that the clinical, arthroscopic, and histological outcomes were comparable on both procedures. Of the 73 patients who did not fail, 46 patients (63%) had excellent results, 18 patients (25%) were good, 6 patients (8%) were fair, and 3 patients (4%) had skint results.
