We reviewed the cases of sixty-three patients who were more than forty years old when they underwent arthroscopic partial medial meniscectomy. Thirty-five patients returned for clinical evaluation and another eight were evaluated by questionnaire and telephone interview. Over the thirty-five-month follow-up period, progressive varus deformity and medial joint-space narrowing were not observed. Of the twenty-seven knees in Group I (non-degenerative tears) that underwent arthroscopic partial meniscectomy, satisfactory results were found in 96 per cent. Of the seventeen knees in Group II (degenerative tears) over-all satisfactory results were found in only 65 per cent. A history of pre-existing degenerative arthritis in patients with degenerative tears seemed to correlate with a less favorable outcome.
我们回顾了63例患者的病例，这些患者在接受关节镜下内侧半月板部分切除术时年龄超过40岁。35例患者返回进行临床评估，另有8例通过问卷调查和电话访谈进行评估。在35个月的随访期内，未观察到进行性内翻畸形和内侧关节间隙变窄。在接受关节镜下半月板部分切除术的I组（非退行性撕裂）的27个膝关节中，96%的结果令人满意。在II组（退行性撕裂）的17个膝关节中，总体满意结果仅为65%。退行性撕裂患者既往存在退行性关节炎病史似乎与较差的结果相关。
