Lower patella–patellar tendon angle is associated with increased odds of patellofemoral osteoarthritis progression in ACL revision patients: A case control study
Abstract Purpose To investigate whether a lower preoperative patella–patellar tendon angle (P‐PTA) is associated with progression of patellofemoral osteoarthritis (PFOA) in patients undergoing anterior cruciate ligament (ACL) revision surgery. We hypothesised that patients with lower preoperative P‐PTA would have highe...
