According to study results, osteochondral autologous transplantation is a safe and reliable procedure for treatment of high-grade osteochondral defects in the patella and resulted in significant improvements in patient-reported outcomes and return to sports.
“[Osteochondral autologous transplantation] OAT should be offered to patients with high-grade patellar chondral defects when nonoperative management has not proven successful in managing anterior knee symptoms,” the authors wrote.
Researchers performed a systematic review and identified five studies with a total of 102 patients who underwent OAT for the treatment of isolated patellar cartilage high-grade defects. These studies addressed patient-reported outcomes, return to sports and MRI at follow-up after OAT.
Results showed all patients outcomes improved significantly at the final follow-up based on the Lysholm, International Knee Documentation Committee, Kujala, Tegner, and SF-36 scores. Of the five studies, four studies had MRIs performed during the first year postoperatively to evaluate the osteochondral plug integration and positioning. Investigators noted that at the final follow-up, most of the plugs were integrated and positioned correctly. There were two studies that queried whether patients were able to return to sports and these showed that in most cases, patients were able to return to their previous level of sport. – by Monica Jaramillo
