The effect of chondral damage and age on the long-term prognosis after partial meniscectomy was investigated in two matched groups of patients (n = 40), one with intact and the other with severely disrupted cartilage at the time of operation. Twelve to 15 years after meniscectomy a clinical and radiographic examination was done. Significantly more patients with intact cartilage (85%) than with chondral damage at operation (50%) had excellent or good knee function (P < 0.05). The activity levels decreased from active individual sports to physical fitness activities (P < 0.001), equally in both groups. Joint space reduction on roentgenograms was seen in 16 patients (80%) with chondral damage and in 6 patients (30%) with intact cartilage (P < 0.001). In addition to chondral damage, age over 30 years (P < 0.04) at the time of operation was associated with a worse functional (P < 0.03) and radiographic (P < 0.01) outcome.
在两组匹配的患者（每组n = 40）中，研究了软骨损伤和年龄对半月板部分切除术后长期预后的影响，一组患者手术时软骨完整，另一组患者手术时软骨严重受损。半月板切除术后12至15年进行了临床和影像学检查。软骨完整的患者中膝关节功能为优或良的比例（85%）显著高于手术时存在软骨损伤的患者（50%）（P < 0.05）。两组患者的活动水平均从积极的个人运动降至健身活动（P < 0.001）。X线片显示，16例（80%）软骨损伤患者和6例（30%）软骨完整患者出现关节间隙变窄（P < 0.001）。除软骨损伤外，手术时年龄超过30岁（P < 0.04）与较差的功能（P < 0.03）和影像学（P < 0.01）结果相关。
