We studied all patients undergoing arthroscopic resection of symptomatic plica without other intraarticular abnormality at our institution from October 1981 to March 1987. To be considered abnormal, plicae had to be thickened and/or fibrotic when viewed arthroscopically. Seventy-six of nearly 2000 patients (4%) who underwent diagnostic arthroscopies met our inclusion criteria. Clinical response after arthroscopic resection was evaluated in 51 patients at an average of 47 months (range, 15 to 77). Excellent or good results were obtained in 57 (75%) of the patients. Eleven patients (14%) had an impingement lesion defined as a localized femoral condylar ridge or groove of the articular surface that impinged upon the plica with increasing flexion. All of these patients had an excellent or good result. Other factors associated with a favorable outcome included a specific preoperative diagnosis localizing symptoms to the medial compartment, onset of pain after a period of increased athletic activity or after a twisting injury, and younger age. Poor prognostic factors included associated chondromalacia and an unclear preoperative diagnosis.
我们研究了1981年10月至1987年3月期间在我院接受关节镜下有症状皱襞切除术且无其他关节内异常的所有患者。关节镜检查时，皱襞必须增厚和/或纤维化才被视为异常。近2000例接受诊断性关节镜检查的患者中有76例（4%）符合我们的纳入标准。对51例患者进行了关节镜切除术后的临床反应评估，平均随访47个月（范围15至77个月）。57例（75%）患者获得了优或良的结果。11例（14%）患者存在撞击性病变，定义为关节面局部股骨髁嵴或沟，随着屈曲增加撞击皱襞。所有这些患者都获得了优或良的结果。与良好预后相关的其他因素包括术前明确诊断症状局限于内侧间室、在一段时间的体育活动增加或扭伤后出现疼痛以及年龄较轻。预后不良的因素包括合并软骨软化症和术前诊断不明确。
