Poster 239: Advanced Patellofemoral Chondromalacia Does Not Affect Outcomes After Meniscal Root Repair

Objectives: Meniscal root tears have been shown to accelerate cartilage breakdown and increase the risk of total knee arthroplasty (TKA) if left unaddressed. Unfortunately, many patients with meniscal already associated chondromalacia which can impact surgical outcomes. The presence advanced in medial or lateral compartmentsof is a known contraindication performing repair; however, effect patellofemoral on outcomes not known. purpose this study was compare repair without (PFC). Methods: A retrospective review prospectively collected data undergoing by single surgeon conducted between January 2016 December 2019. Patients were included they had undergone an isolated posterior repair. performed using transtibial suture technique. placed into one two groups depending amount present at time surgery. Outerbridge grade 0-2 Minimal Patellofemoral Chondromalacia (MPFC) Group. 3-4 changes found surgery (PFC) compartment excluded from study. Lysholm Knee Scoring Scale International Documentation (IKDC) Subjective Form preoperatively, 6,12 24 months after Clinical followed recurrent tear, conversion arthroplasty, arthrofibrosis requiring manipulation under anesthesia/lysis adhesions infection. PASS MCID determined repairs other literature. Continuous compared two-tailed student-T test while categorical utilizing chi-square testing. Results: 27 made up PFC group 54 MPFC group.
