Osteochondral autologous graft transfer system in the knee; mid-term results

The purpose of this study was to determine the effectiveness of the osteochondral autologous graft transfer system in the treatment of chondral and osteochondral lesions of the knee.

Sixty five knees of sixty four patients who underwent autologous osteochondral graft transfer were evaluated with clinical scores and imaging techniques.

The average follow up was 82.2 (51-145) months. The patients were evaluated according to Tegner activity scale, Lysholm scale and IKDC subjective knee evaluation form. According to all these scales, all patients showed increasing results in various rates in the last follow up. Accordingly, mean increases of 59.2±15.9 points, 3.6±1.4 points, and 42.6±11.5 points were achieved in Lysholm knee scores, Tegner activity scale scores, and IKDC subjective knee evaluation form, respectively (p≤.0001). Moreover, we found no significant correlation between functional results and age, functional results and localization of osteochondral defect, functional results and additional knee pathologies.

In our study we achieved significant increases in all the scales in the last follow up. Furthermore, we found no significant correlation between functional results and age, defect localization and additional knee pathologies.
