Total knee arthroplasty (TKA) is an effective treatment for patients with end-stage symptomatic knee osteoarthritis. As the aging population grows, the demand for the procedure is projected to increase. While highly successful, TKA has associated risks and complications. Complex regional pain syndrome is one uncommon but debilitating complication that can negatively impact patient satisfaction and quality of life. We present a case of complex regional pain syndrome in the operated leg that resulted in significant functional deficits. Key findings of this case include significant and disproportionate pain in the joint, altered cutaneous sensation around the joint, and decreased range of motion in flexion in the absence of any mechanical issues with the TKA. Because of the debilitating nature of this condition, patients must be fully informed of and realize the risks associated with undergoing a widely appreciated procedure such as TKA.
全膝关节置换术（TKA）是终末期有症状的膝关节骨关节炎患者的有效治疗方法。随着人口老龄化加剧，预计该手术的需求将会增加。虽然TKA非常成功，但也存在相关风险和并发症。复杂性区域疼痛综合征是一种罕见但使人衰弱的并发症，会对患者满意度和生活质量产生负面影响。我们报告一例手术侧腿部发生复杂性区域疼痛综合征并导致严重功能缺陷的病例。该病例的主要发现包括关节处显著且不成比例的疼痛、关节周围皮肤感觉改变，以及在TKA不存在任何机械问题的情况下屈曲活动范围减小。由于这种病症使人衰弱的特性，必须让患者充分了解并认识到接受像TKA这样广受认可的手术所伴随的风险。
