对行半月板切除术的３６名青少年作了远期随访，随访时间为１０～３３年，平均１５．２年，结果优良率达到６１．１％。统计学分析表明远期临床疗效与随访时间有显著相关性，但与术前病程长短无关。Ｘ线检查发现有８４％的膝关节发生退行性改变，但退变程度与临床疗效并无明确联系。作者认为，半月板切除对膝关节的生物力学功能具有明显的影响，因此早期处理膝半月板损伤时应尽可能完整地保留半月板。 Thirty-six adolescents who underwent meniscectomy were followed up for 10 to 33 years (average 15.2 years). The excellent and good rate was 61.1%. Statistical analysis showed that long-term clinical efficacy and follow-up time were significantly correlated, but not with the duration of preoperative duration. X-ray examination found that 84% of knee degenerative changes, but the degree of degeneration has no clear relationship with clinical efficacy. The authors believe that meniscectomy has a significant effect on the biomechanical function of the knee joint, so early treatment of meniscus injury should be as complete as possible to retain the meniscus.
