Exclusion criteria included prior or concomitant knee injuries, surgeries, or syndromes. Delayed surgery was defined as \u226590 days after diagnosis. PTOA diagnosis was defined by billing codes. Motion restoration procedures (MRPs) before PTOA diagnosis were recorded. Multivariable logistic and Cox regression were used to assess risk factors for PTOA at 5 and 10 years.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n A total of 7555 meniscectomy (mean age 14.7, 50% women) and 2797 meniscal repair (mean age 14.4 years, 46% women) patients met inclusion criteria. At 5 years, PTOA occurred in 2.2% of meniscectomy and 1.4% of repair patients. At 10 years, rates were 2.3% and 1.5%, respectively. Average time to PTOA was 737 days (meniscectomy) and 862 days (repair). When disaggregated by sex, there was no significant difference in sex makeup of those who did and did not develop PTOA (\n P<\/jats:italic>\n \u2009=\u2009.430). In the meniscectomy group, risk factors for 10\u2010year PTOA included MRP (hazard ratio [HR] 6.28,\n P<\/jats:italic>\n \u2009<\u2009.001), age \u226512 at surgery (HR 4.84,\n P<\/jats:italic>\n \u2009=\u2009.027), and obesity (HR 1.84,\n P<\/jats:italic>\n \u2009<\u2009.001). In the repair group, MRPs (HR 5.23,\n P<\/jats:italic>\n \u2009=\u2009.023) and depression (HR 2.02,\n P<\/jats:italic>\n \u2009=\u2009.027) were significant. These same risk factors were identified for 5\u2010year PTOA.\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n The 10\u2010year incidence of PTOA was 2.2% after meniscectomy and 1.5% after meniscal repair in pediatric patients. MRPs were a consistent risk factor. Age \u226512 and obesity were associated with PTOA after meniscectomy. Depression was associated with PTOA after repair.<\/jats:p>\n <\/jats:sec>\n \n Level of Evidence<\/jats:title>\n Level III, retrospective cohort study.<\/jats:p>\n
