Wear-induced osteolysis remains a common problem after total knee arthroplasty and may be particularly difficult to detect clinically or radiographically around the femoral component. We describe the use of magnetic resonance imaging to identify particulate-induced osteolysis around the distal femur and proximal tibia in 2 patients with total knee arthroplasties. The extent of the osteolysis was not apparent from standard x-rays, and the information provided by the magnetic resonance imaging facilitated preoperative discussion with the patient as well as preoperative planning for the surgery.
磨损性骨溶解仍是全膝关节置换术后常见的问题，在股骨部件周围通过临床或影像学检查可能尤其难以发现。我们描述了在2例全膝关节置换患者中使用磁共振成像来识别股骨远端和胫骨近端周围颗粒诱导的骨溶解。标准X线片上骨溶解的程度并不明显，而磁共振成像提供的信息有助于术前与患者的沟通以及手术的术前规划。
