Bipolar fresh total osteochondral allograft in the ankle: Is it a successful long-term solution?

The use of BFTOA represents an intriguing option to arthrodesis or arthroplasty. A satisfactory clinical result associated to a good movement of the transplanted joint is to be expected up to short-mid-term, overtime. Long term, the range of motion (ROM) is progressively decreased up to spontaneous arthrodesis in some cases, still the joint results pain free and patient's perception is of a well functioning ankle. A deeper knowledge of the immunological behavior of transplanted cartilage is needed in order to improve the durability of this fascinating technique.
