应用同种异体骨重建胫骨近端或股骨远端或两者都有的缺损区，共28例患者30膝，行翻修全膝关节置换术，患者指征时平均年龄65.8岁(24~89岁)。中位数36个月)术后23膝(21例)评分增加至少20分，不需要额外手术治疗，成功率为77%，其余7膝因感染(3膝)、胫骨假体松动(2膝)、植骨骨折(1膝)、异体骨-宿主接合处骨不连(1膝)等原因被认为失败，正确应用同种异体骨可重建大量骨缺损，为植入物提供稳定和支撑。并在需要额外手术治疗的情况下恢复骨储备。
Allograft bone was used to reconstruct a defect in the proximal aspect of the tibia or the distal aspect of the femur, or both, in thirty knees of twenty-eight patients who had a revision total knee arthroplasty, The average age of the patients at the time of the index procedure was 65.8 years (range, twenty-four to eighty-nine years).At an average of fifty months (range, twenty-four to 132 months; median, thirty-six months) postoperatively, the score for twenty-three knees (twenty-one patients) had increased by at least 20 points, and these knees did not need additional operative treatment, Thus, the rate of success was 77 per cent, The procedure was considered a failure for the remaining seven knees because of infection (three), loosening of the tibial component (two), fracture of the graft (one), and non-union at the allograft-host junction (one), Properly applied allograft can be used to reconstruct massive bone defects, provide stability and support for implants, and restore bone stock in the event that additional operative treatment is necessary.
