Outcomes of Osteochondral Allograft Transplantation with versus without Concomitant Meniscus Allograft Transplantation: A Comparative Matched Group Analysis

Objectives: While osteochondral allograft transplantation (OAT) is often performed with concomitant meniscus allograft transplantation (MAT) as a strategy for knee joint preservation, the impact of concomitant MAT on outcomes following OAT has not been assessed. The purpose of this study was to determine clinical outcomes for patients undergoing OAT with MAT compared to a matched cohort of patients undergoing isolated OAT. Methods: A review of consecutive patients who underwent OAT by a single surgeon with a minimum follow-up of 2 years was conducted. Patients who underwent OAT without concomitant MAT were compared to a matched group of patients who underwent OAT with concomitant MAT (age ± 3 years, gender, BMI ± 5 kg/m2, number of previous ipsilateral knee surgeries ± 1, and the presence of concomitant ligamentous surgery). The reoperation rate, failure rate, timing of reoperation, procedures performed, findings at surgery, and patient reported outcome scores were reviewed. Failure was defined by revision OAT, conversion to knee arthroplasty, or gross appearance of graft failure at 2nd look arthroscopy. Descriptive statistics, fisher’s exact or chi-square testing, and Mann-Whitney U testing were performed, with P0.05 for all for both groups). The SF-12 mental subscale was not significantly improved at final follow-up for either group. MAT patients demonstrated significantly higher SF-12 physical subscale as compared to non-MAT patients at most recent follow-up (45.81±7.42 vs 42.07±7.97, P
