Abstrakt: Introduction: Symptomatic talar osteochondral lesions are about 50% refractory to conservative treatment requiring a surgical solution. In the case of large chronic lesions, the use of bone graft taken from tissue bank is an alternative that enables to fill the defect without causing donor site morbidity.
Material and Methods: Eight patients treated with talar osteochondral allograft in lesions greater than 20mm in diameter were analyzed - 4 males and 4 females aging 39.5 years old on average. Evaluation was performed according to AOFAS scale and VAS as well as incorporation and continuation evaluations according to CT and MRI studies. A follow-up of 46.8 months on average was done.
Results: A 34.6-point improvement on average according to AOFAS. A 6.7-point pain improvement on average according to VAS. Incorporation in 100% of the cases. Two cases showed partial resorption and one case showed peri-graft lysis less than 30%. There was no collapse.
Conclusions: Fresh frozen osteochondral allografts are a viable alternative when treating large osteochondral lesions, thereby avoiding morbidity of autologous donor areas or arthrodesis procedures.
