In patients treated for focal cartilage defects of the knee with osteochondral grafts, these values can be used to define a clinically important change and substantial clinical benefit for future outcome studies. In this study population, higher preoperative activity levels and a history of 1 or less previous ipsilateral knee surgeries were predictive of achieving a clinically important change and substantial clinical benefit after OAT/OCA. These findings have implications for

OCA in elite basketball players results in an 80% return to previous level of competition, which is consistent with previous reports of athletes playing other sports. Osteochondral allografting is a reasonable option to consider for full-thickness cartilage lesions of the knee, even for elite jumping athletes.

This study found significantly improved pain and function in patients treated with PJAC for symptomatic patellofemoral articular cartilage defects. No patients required reoperation for graft-related issues. Postoperative MRI revealed majority lesion fill in more than 69% of patients, but persistent morphologic differences between graft site and normal adjacent cartilage remain. Though we support PJAC use in this setting to improve patient subjective outcomes, improved appearance on postoperative imaging was not

Purpose To compare failure rates and clinical outcomes of osteochondral allograft transplantation (OCA) in anterior cruciate ligament (ACL)-intact versus ACL-reconstructed knees at midterm follow-up. Methods After a priori power analysis, a prospective registry of patients treated with OCA for focal chondral lesions ≥2 cm2 in size with minimum 2-year follow-up was used to match ACL-reconstructed knees with ACL-intact knees by age, sex, and primary chondral defect location. Exclusion criteria included meniscus transplantation, realignment osteotomy, or
