A 54-year old woman with primary osteoarthritis and a tibial bone marrow lesion underwent subchondroplasty with injectable calcium phosphate. Post-operatively, the patient's symptoms worsened, and she lost the ability to bear weight. Follow-up MRI revealed previously absent, diffuse STIR hyperintensity in the tibia extending far beyond the surgical site. Twelve months post-operatively, symptoms spontaneously resolved. As the prevalence of subchondroplasty grows it will be important to recognize potential complications. To the authors' best knowledge this is the first report of significantly worsening pain and difficulty bearing weight corresponding with diffuse hyperintense T2 signal in the tibia after a calcium phosphate subchondroplasty.
一位 54 岁的女性，原发性骨关节炎和胫骨骨髓病变，接受了可注射磷酸钙的软骨下成形术。术后，患者症状加重，无法承重。随访 MRI 显示胫骨弥散性 STIR 高信号，先前未见，远远超出手术部位。术后 12 个月，症状自发缓解。随着软骨下成形术的普及，认识潜在的并发症将变得非常重要。据作者所知，这是首例报道的磷酸钙软骨下成形术后胫骨弥漫性 T2 信号高导致疼痛明显加重和承重困难的病例。
