Objectives:

Due to an impairment of the ability to regenerate hyaline cartilage the treatment of cartilage defects requires a special therapy. Our objective was to report case of an osteochondral allograft transplant in the medial femoral condyle of a dog.

Methods:

A 9 year old male beagle was presented to our veterinary clinic, 3 months after surgery for a cruciate ligament rupture, with a severe lameness of the left hind limb. A capsular tear, a grade 2 patellar luxation and an osteochondral lesion of approximately 1x1x1 cm on the medial femoral condyle were diagnosed. Because the patient showed a persistent lameness after surgical treatment for the patellar luxation and debridement of the ostechondral lesion, we decided to use an osteochondral allograft for treatment of the osteochondral lesion. An allograft from a donor dog was prepared and fitted into the defect and secured with a crossed-pin technique.

Results:

Due to implant loosening, one of the pins was removed in a subsequent surgery. At final follow-up, radiography and computed tomography demonstrated good incorporation of the allograft and the dog showed a significant clinical improvement.

Conclusions:

Compared to other organ transplants osteochondral allografts display reduced imunogenicity. This is mainly due to the avascularity of the tissue and the chondrocyte-surrounding bone matrix. Osteochondral allografts are less prone to graft failure and might be considered as a good treatment option for large cartilage lesions.
