Seventy-five patients with 86 complex tears of the medial meniscus posterior horn (posterior medial complex disruptions) treated by arthroscopic partial meniscectomy were contacted for evaluation of their functional results. Forty-five patients returned for physical and radiographic examination 1 to 6 years after surgery. Condylar chondromalacia was significantly higher in patients waiting to undergo surgery over 6 months from the onset of their symptoms (94%) than those waiting less than 6 months (40%) (P = .0001). Patients were classified into phases based on preoperative x-rays and the operative presence of condylar chondromalacia. Satisfactory results were seen in 87% of phase 0 and phase 1 patients, 50% of phase 2 patients, and 32% of phase 3 patients. Phase classification provided significant data for prognostication of satisfactory results (P = .0001). With advancing age, presence of preoperative x-ray changes, the articular cartilage damage may compromise the results. Most patients in this study exhibited clinical improvement suggesting some benefit from the mechanical washout, if not the meniscectomy.
我们联系了75例接受关节镜下部分半月板切除术治疗的内侧半月板后角复杂撕裂（后内侧复合体损伤）患者（共86处撕裂），以评估其功能结果。45例患者在术后1至6年返回进行体格检查和影像学检查。症状出现后等待手术超过6个月的患者髁软骨软化症发生率（94%）显著高于等待时间少于6个月的患者（40%）（P = 0.0001）。根据术前X线片及术中髁软骨软化症的情况将患者分为不同阶段。0期和1期患者中87%取得满意结果，2期患者中50%取得满意结果，3期患者中32%取得满意结果。阶段分类为满意结果的预后提供了重要数据（P = 0.0001）。随着年龄增长、术前X线片出现改变，关节软骨损伤可能会影响结果。本研究中的大多数患者都有临床改善，这表明即使半月板切除术没有效果，机械性冲洗也有一定益处。
