Purpose
Knee arthrodesis is a scarcely tolerated procedure with a strong negative impact on the quality of life of the patient. The use of a fresh osteochondral allograft represents a fascinating option for a biological joint reconstruction. Aim of this report is to describe a case of total femoral and tibial osteochondral allograft used for reversing a non-tolerated knee fusion in a young patient and to report the clinical and radiographic results obtained at a 4-year follow-up.
Methods
A 22-year-old man with right knee arthrodesis received a reversion of the arthrodesis with a total femoral and tibial osteochondral allograft. Clinical and radiographical evaluations were carried out periodically up to 48 months.
Results
At 48 months of follow-up, the patient had full integration of the allograft with a range of motion from 0° to 80°. Clinical scores improved from preoperative to final follow-up (IKDC from 25 to 65, KOOS from 32 to 65 and WOMAC from 30 to 74). Radiographic arthritis occurrence of the transplanted surfaces was evident at follow-up.
Conclusions
Despite the good clinical results achieved in the case described, a wider applicability of total femoral and tibial osteochondral allograft requires further studies on long-term larger allograft survival. Arthritis recurrence of the transplanted surfaces is cause of concern. Causes and possible solutions need to be more deeply investigated.
