While previous studies have shown that OCA transplantation to the patellofemoral joint can have an increased risk of failure compared to other areas of the knee, bipolar OCA transplantation to the patella and trochlea using tissue from the same donor can be a good option. At short to mid-term follow-up, this technique demonstrated significant improvement for recurrent dislocation and high grade chondral lesions.
The purpose of this study is to assess midterm clinical and radiographic outcomes after fresh osteochondral allograft transplantation (OAT) for large femoral head lesions at minimum 2-year follow-up.
To determine if contralateral grafts could be used for OCD lesions up to 20mm. This research contributes to the growing body of knowledge that using a lateral femoral condyle is an acceptable option.
Dr. LaPrade recently published a case report for transplanting a very large trochlear allograft in a 21 year old female patient with trochlea dysplasia.
Patient satisfaction was high following the OCA transplantation, with the rate remaining constant over time. We observed a strong association between patient satisfaction and measures of pain, function, activity level, and quality of life following OCA transplantation.
Many cartilage repair algorithms use lesion size to choose the appropriate surgical technique. The purpose of this study was to determine if lesion size affects outcomes after an osteochondral allograft (OCA) transplantation. The results of this study suggest that graft size does not influence outcomes or survivorship. OCA transplantation is an effective treatment in the femoral condyle regardless of size.
