Osteoarthritis of the knee is common after total medial meniscectomy. In anterior cruciate ligament-intact knees, the reported outcomes of partial medial meniscectomy are variable. Radiographic assessment using a posteroanterior weight-bearing view is a reliable tool for detecting minor medial joint space narrowing, which may be an early sign of osteoarthritis. Studies that assessed the effect of partial medial meniscectomy found a low percentage of patients with >50% joint narrowing at 10 to 15 years after surgery. Digital radiography, using a posteroanterior weight-bearing view, is a highly sensitive method for observing minor joint space narrowing in the involved knee. A recent study showed that 88% of patients who underwent partial medial meniscectomy had joint space narrowing of <2 mm, and none had narrowing >or=2 mm, at a mean follow-up of 12 years. Subjective results after partial medial meniscectomy are favorable, with 88% to 95% of patients reporting good to excellent results.
全内侧半月板切除术后膝关节骨关节炎很常见。在前交叉韧带完整的膝关节中，部分内侧半月板切除术的报告结果不一。使用后前位负重位X线片进行影像学评估是检测内侧关节间隙轻微变窄的可靠工具，这可能是骨关节炎的早期迹象。评估部分内侧半月板切除术效果的研究发现，术后10至15年关节间隙狭窄>50%的患者比例较低。使用后前位负重位的数字X线摄影是观察患侧膝关节轻微关节间隙变窄的高度敏感方法。最近一项研究表明，平均随访12年时，接受部分内侧半月板切除术的患者中，88%的患者关节间隙狭窄<2mm，无一例狭窄≥2mm。部分内侧半月板切除术后的主观结果良好，88%至95%的患者报告结果为良好至优秀。
