Twenty-eight out of a group of 38 patients, who had undergone a patellectomy during the period 1950-70, were investigated clinically and radiologically. The results were compared with the subjective symptoms of the patients to see if there was a correlation. The follow-up period was 7.4 years on average. A good subjective result was reported by only six patients. The predominant subjective symptoms were weakness of the limb and pain on movement and/or exertion. The most usual findings were atrophy of the quadriceps muscle, crepitation, and palpation tenderness. The muscular power of the quadriceps was found to be greater than or equal to 75 per cent of the power of the intact knee in only seven cases (25 per cent).
在1950年至1970年期间接受髌骨切除术的38名患者中，对28名患者进行了临床和放射学调查。将结果与患者的主观症状进行比较，以查看是否存在相关性。平均随访期为7.4年。只有6名患者报告主观结果良好。主要的主观症状是肢体无力以及运动和/或用力时疼痛。最常见的发现是股四头肌萎缩、摩擦音和触压痛。仅在7例（25%）中发现股四头肌肌力大于或等于健侧膝关节肌力的75%。
