A private payer database was used to examine the incidence and rates of knee arthroscopy in patients less than 65 years of age and the subsequent risk of knee arthroplasty. Time to event analysis was performed using the Kaplan-Meier method; also, Cox regression analysis was used to evaluate the relative risk of subsequent knee arthroplasty for arthroscopic patients. Overall, 247,034 knee arthroscopies, done for injury or arthropathy, were identified between 2004 and 2009. Within 1-year of arthroscopy, 2.2% of arthropathy patients and 0.9% of injury patients underwent a knee arthroplasty. These increased to 5.2% and 2.4% at 5-years, respectively. The risk of arthroplasty following arthroscopy increased significantly with age. Further study is warranted to examine the benefit of arthroscopy in younger patients with OA.
使用私人支付者数据库研究了 65 岁以下膝关节镜手术的发生率和比率，以及随后膝关节置换术的风险。采用 Kaplan-Meier 法进行时间事件分析；同时，采用 Cox 回归分析评估膝关节镜患者后续膝关节置换术的相对风险。总体而言，2004 年至 2009 年间共进行了 247034 例膝关节镜检查，用于治疗损伤或关节炎。在膝关节镜检查后 1 年内，关节炎患者中有 2.2%和损伤患者中有 0.9%接受了膝关节置换术。分别在 5 年内增加至 5.2%和 2.4%。膝关节镜检查后进行关节置换术的风险随年龄显著增加。需要进一步研究以检查在患有 OA 的年轻患者中进行关节镜检查的益处。
