Total knee arthroplasty achieves consistently excellent results in most patients. The most common causes of failure are loosening and infection. This article reviews the records of five patients in whom intraarticular fibrous tissue hypertrophy was the cause of pain after total knee arthroplasty. All of the patients had increasing pain and decreasing knee motion. Evaluation for loosening, malalignment, intraarticular debris, and infection gave negative results. Examination revealed a blocked range of motion and a palpable, tender, intraarticular mass. Injection of anesthetic relieved the symptoms. Surgical excision of the hypertrophic fibrous tissue relieved symptoms and increased knee range of motion. This cause of pain in the total knee arthroplasty patient is rare.
全膝关节置换术在大多数患者中都能持续取得优异的效果。最常见的失败原因是假体松动和感染。本文回顾了5例全膝关节置换术后关节内纤维组织增生导致疼痛患者的病历。所有患者均有疼痛加剧和膝关节活动度下降的情况。对假体松动、对线不良、关节内碎片和感染进行评估，结果均为阴性。检查发现活动范围受限，可触及关节内肿块并有压痛。注射麻醉剂可缓解症状。手术切除增生的纤维组织可缓解症状并增加膝关节活动范围。全膝关节置换术患者出现这种疼痛原因较为罕见。
