Advanced Patellofemoral Chondrosis Linked to Higher Arthroplasty Rate After Meniscus Root Repair

A single-center retrospective cohort study compared outcomes of posterior medial meniscus root repair in patients with and without advanced patellofemoral chondrosis (Outerbridge grade 3 or higher). The study reported that patient-reported outcomes, retear rates, and revision meniscal surgery rates were similar between groups, but conversion to unicompartmental or total knee arthroplasty was nearly seven times more common in patients with advanced patellofemoral chondrosis (14.9% vs 2.1%). The authors state this suggests advanced patellofemoral chondrosis may predispose patients to earlier joint degeneration and need for arthroplasty despite preserved short- to midterm functional outcomes.

Most relevant for: Patients being evaluated for or undergoing posterior medial meniscus root repair, particularly those with concomitant advanced patellofemoral cartilage damage.
