Failures in bipolar fresh osteochondral allograft for the treatment of end-stage knee osteoarthritis

摘要

Bipolar fresh osteochondral allografts (BFOA) recently became a fascinating option for articular cartilage replacement, in particular in those young patients non-suitable for traditional replacement because of age. While the use of osteochondral allografts for the treatment of focal osteochondral lesions in the knee is well established, their use in the treatment of end-stage arthritis is far more controversial. The purpose of this paper is to describe our experience in a series of seven patients who underwent a resurfacing of both tibio-femoral and patello-femoral joints by BFOA.
