For the purpose of investigating the clinical efficacy of a newly designed wedged insole, 149 patients with medial osteoarthritis of the knee were followed from one year to five years and five months. A rating system for pain, walking ability, and both were used for evaluation of the clinical results. Comparing two groups consisting of 107 patients with early radiographic stages (Stage I or II), 67 patients (Group I) treated with both a wedged insole and anodyne (Indomethacin 600 mg/day) showed a significantly greater improvement than 40 patients (Group II) treated with anodyne alone. Analyzing the therapeutic efficacy of the wedged insole according to the radiographic stage, the prescription of a wedged insole was significantly more effective for patients with mild osteoarthritis (Stages I, II, and III), and ineffective for those with advanced osteoarthritis (Stage IV). The wedged insole, designed on the basis of an established hypothesis, represents an excellent means of conservative treatment for early medial osteoarthritis of the knee.
为了研究一种新设计的楔形鞋垫的临床疗效，对149例膝内侧骨关节炎患者进行了为期1年至5年零5个月的随访。采用疼痛、行走能力以及两者的评分系统来评估临床结果。比较由107例早期影像学分期（I期或II期）患者组成的两组，67例（I组）同时使用楔形鞋垫和止痛药（吲哚美辛600毫克/天）治疗的患者比40例（II组）仅使用止痛药治疗的患者改善明显更大。根据影像学分期分析楔形鞋垫的治疗效果，楔形鞋垫的处方对轻度骨关节炎（I期、II期和III期）患者明显更有效，而对晚期骨关节炎（IV期）患者无效。基于既定假设设计的楔形鞋垫是早期膝内侧骨关节炎保守治疗的一种极佳手段。
