We describe a symptomatic, progressive restriction of knee flexion due to an accessory quadriceps femoris in a nine-year-old girl. There was no history or findings of post-injection fibrosis, nor any obvious swelling of the affected quadriceps. At arthroscopy no intra-articular pathology was found. An accessory 'quinticeps femoris' was diagnosed by ultrasonography and MRI. Following excision of the muscle and tendon full flexion of the knee was regained and there was no recurrence of the contracture.
我们描述了一名9岁女孩因股四头肌副肌导致膝关节屈曲出现症状性、进行性受限的情况。没有注射后纤维化的病史或相关表现，受累股四头肌也没有明显肿胀。关节镜检查未发现关节内病变。通过超声和磁共振成像诊断出存在副“股五头肌”。切除该肌肉和肌腱后，膝关节恢复了完全屈曲，挛缩未复发。
