Podium Presentation Title: The Effect of Platelet-Rich Plasma Therapy on Rate and Timing of Meniscectomy

Platelet-rich plasma (PRP) therapy may provide a treatment option for meniscal tears without surgery. This study examines how PRP affects time to and rate of meniscectomy in patients with tears. A large insurance database was queried CPT code meniscus tear between 2015-2018. Groups were stratified by injection. Cohorts matched age, gender, Charlson Comorbidity Index, comorbid osteoarthritis. The primary outcome meniscectomy. Secondary Significance p=0.05. Our sample provides >90% power detect 10% difference rates groups. Nine hundred fifty-six who received injection 956 controls. Patient demographics balanced Six sixteen (64.4%) group vs. 419 (43.8%) controls underwent (P<0.0001). No observed control groups (median 28 [IQR 11-84] 34 15-80] days, respectively, P = 0.41). In patients, significant predictors included osteoarthritis (adj-OR=1.38, 95%CI 1.02-1.88, P=0.04), complex type (adj-OR=2.12, 1.48-3.09, P<0.0001), presence both medial- lateral-sided (adj-OR=3.95, 2.07-7.53, P<0.0001). Tear types that non-significant bucket-handle 0.73-2.70, P=0.34), peripheral (adj-OR=1.63, 0.93-2.94, P=0.10), medial-only (adj-OR=1.24, 0.70-2.18, P=0.46 lateral-only (adj-OR=1.32, 0.70-2.48, P=0.39). Patients more likely undergo injections did not significantly delay diagnosis osteoarthritis, tears, medial lateral
