Cohort study 

研究目的:

主要目的:明确术前 IPFP MRI 信号分层对早中期 KOA 患者关节镜清理术后 5 年无 TKA 事件生存期及终末期 TKA 累积发生风险的独立预测价值 次要目的: 1. 评估 IPFP 信号分层对术后 1/2/5 年疼痛与功能改善及 MCID 达标率的影响; 2. 分析其对影像学进展、二次手术及镇痛药物依赖的预测价值; 3. 通过亚组分析锁定关节镜清理术最优获益人群  

Objectives of Study:

Primary objective: To determine the independent predictive value of preoperative IPFP MRI signal stratification on 5-year TKA-free survival and cumulative incidence of end-stage TKA in patients with early-to-mid stage KOA after arthroscopic debridement Secondary objectives: 1. To evaluate the effect of IPFP signal stratification on pain and function improvement and MCID achievement rate at 1/2/5 years postoperatively; 2. To analyze its predictive value for radiographic progression, reoperation and analgesic dependence; 3. To identify the optimal benefit population of arthroscopic debridement through subgroup analysis
