Calcific myonecrosis (CM) is a rare soft tissue condition associated with previous trauma that presents with a large lower extremity mass and can be misdiagnosed as a malignancy. Biopsy, accidental entry, or disturbance to the lesion can be accompanied by a high risk of complications. We present the case of a 72-year-old man with severe post-traumatic knee arthritis, as well as a large pretibial mass consistent with CM, who successfully underwent total knee arthroplasty. To our knowledge, this is the first report focusing on total knee arthroplasty in a patient with CM and we discuss considerations for evaluation, tourniquet usage, component positioning and placement, postoperative care, and range-of-motion expectations.
钙化性肌坏死（CM）是一种与既往创伤相关的罕见软组织疾病，表现为下肢出现大肿块，可能被误诊为恶性肿瘤。对病变进行活检、意外刺入或扰动都可能伴有高并发症风险。我们报告了一例72岁男性患者，患有严重的创伤后膝关节炎，以及一个与CM相符的胫前大肿块，该患者成功接受了全膝关节置换术。据我们所知，这是第一份聚焦于CM患者全膝关节置换术的报告，我们讨论了评估、止血带使用、假体组件定位和放置、术后护理以及活动度预期等方面的注意事项。
