Abstract(s)

OBJECTIVES: The treatment of severe post-traumatic ankle arthritis remains a challenge nowadays. Since patients suffering from this pathology are mainly young and active people, a correct reconstruction, if possible, of the articular cartilage defects of the tibiotalar joint is very important to achieve a good result. Fresh bipolar osteochondral allograft (FBOA) is a promising operative technique, as an alternative to arthrodesis and total ankle replacement, in pain relief, restoration of function and indefinite delay of arthritic disease progression. METHODS: The authors made a review of the literature and present a case report of a young 30 years-old man, with bilateral post-traumatic osteoarthritis of the ankle, treated with (FBOA). The patient was evaluated clinically and radiographically monthly. RESULTS: Pain relief and postoperative function was significantly improved reaching 94 points in the left ankle (preoperative of 40 points), and 92 points in the right ankle (preoperative 42 points) AOFAS score. CONCLUSIONS: Fresh tibiotalar allografting seems to be a good alternative to arthrodesis and prosthetic replacement, in the treatment of ankle arthropathy and big articular cartilage defects mainly in young and active patients. This procedure achieves a good pain relief, maintaining functional joint motion and decreasing the risk of adjacent joint arthritis.
