Bone prosthesis composite (BPC) had been widely-used in reconstruction after wide excision of malignant tumors around the knee. However, implant selection for BPC remains a dilemma. Forty-one patients with high-grade malignant bone tumors around the knee who underwent excision and reconstruction with BPC and rotating hinged knee (RHK) prosthesis were included. The mean follow-up time was 54 months (range, 31-78 months). The average Musculoskeletal Tumor Society Rating score was 93.4% (range, 73-100%). The mean range of motion was 125°. Complications included 2 local recurrences, 2 nonunions, and 1 peri-prosthetic fracture. The reconstruction with BPC using the RHK prosthesis provided consistently good functional results with a low complication rate. The RHK prosthesis is a promising choice for BPC reconstruction.
骨假体复合材料（BPC）已广泛应用于膝关节周围恶性肿瘤广泛切除后的重建。然而，BPC的植入物选择仍然是一个难题。纳入了41例膝关节周围高级别恶性骨肿瘤患者，这些患者接受了BPC和旋转铰链膝关节（RHK）假体切除及重建手术。平均随访时间为54个月（范围31 - 78个月）。肌肉骨骼肿瘤学会评分平均为93.4%（范围73 - 100%）。平均活动范围为125°。并发症包括2例局部复发、2例骨不连和1例假体周围骨折。使用RHK假体的BPC重建提供了持续良好的功能结果，并发症发生率低。RHK假体是BPC重建的一个有前景的选择。
