The purpose of this study was to evaluate for changes in the incidence of arthroscopic meniscal procedures, especially meniscal allograft transplantation (MAT) in New York State (NYS) between 2005 to 2014.The New York Statewide Planning and Research Cooperative Systems (SPARCS) database was queried from 2005 through 2014 to identify patients undergoing meniscetomies, meniscal repairs, and MAT. Patients were followed longitudinally to determine the incidence of subsequent ipsilateral knee procedures. The impact of patient demographics and surgeon volume on reoperation was explored.From 2005 through 2014, there were 524,737 arthroscopic meniscal procedures. Of these, there were 510,406 meniscectomies, 14,214 meniscal repairs, and 117 MATs. The number of MATs increased 15.5% per year, with the largest increase being between 2013 to 2014 (an increase of 86.5%). Average MAT patient age was 29.8 ± 11.1 years; 65.0% of patients were male; 66% were Caucasian; 84% were privately-insured; and 23% of surgeons met the criteria for high-volume (five or more MATs in a year). A total of 25.6% (30/117) patients underwent subsequent surgery; 26 patients underwent knee procedures at mean of 18.9 ± 18.3 months after initial MAT, the most common of which were ipsilateral meniscectomies (19/26). Four patients underwent total knee arthroplasty (TKA) at a mean of 21.0 ± 9.2 months after initial MAT. Patients undergoing TKA after MAT were significantly older (42.0 ± 15.0 years vs, 29.3 ± 10.7 years; p = 0.0242) than patients who did not. Neither demographics nor surgeon volume were statistically significant factors for undergoing subsequent surgery (p0.05).Meniscal allograft transplantation, though relatively uncommon, is being performed with greater frequency in NYS. Surgeons should counsel patients regarding the likelihood of requiring subsequent knee surgery after MAT, with repeat arthroscopic partial meniscectomy being the most commonly performed procedure. |
