Thirty-six patients with reflex sympathetic dystrophy primarily affecting the knee were reviewed. Injuries or operation about the patellofemoral joint triggered its onset in 64% of patients. Co-existent mechanical derangement of the knee was present in 64% of patients. Those patients who underwent sympathetic blockade or sympathectomy within one year of onset of symptoms had significantly better pain and function scores than those in whom intervention was later. Early diagnosis remains the key to successful management. Surgery for co-existent mechanical derangement in the affected knee should not be performed until the syndrome is controlled.
回顾了36例主要累及膝关节的反射性交感神经营养不良患者。髌股关节周围的损伤或手术引发了64%患者的发病。64%的患者存在膝关节并存的机械性紊乱。在症状出现一年内接受交感神经阻滞或交感神经切除术的患者，其疼痛和功能评分明显优于干预较晚的患者。早期诊断仍然是成功治疗的关键。在综合征得到控制之前，不应针对患侧膝关节并存的机械性紊乱进行手术。
