The aim of this study was to assess the outcome of periprosthetic fractures above a total knee arthroplasty treated by LISS plate fixation. The primary outcome measure was the radiological union. Secondary outcome measures were knee function using the Oxford Knee Score, and quality of life using the SF-12 questionnaire. Over a 4-year period we treated 16 supracondylar periprosthetic fractures with a LISS plate in 15 patients. Eleven patients (12 fractures) were followed up for an average of 8 months. Eleven out of these 12 fractures went on to unite in an average of 3.7 months. Functional outcome questionnaires were filled out by 9 patients. Suitable matches were found for a subgroup of 5 patients (6 LISS plates). No statistically significant differences were found in the Oxford knee scores (p = 0.749) or quality of life scores (p = 0.440) between the two groups. Our data suggest favourable outcomes after LISS plate fixation of supracondylar periprosthetic femoral fractures above total knee replacement.
本研究旨在评估采用锁定加压钢板（LISS）内固定治疗全膝关节置换术后假体周围髁上骨折的疗效。主要观察指标为影像学骨愈合。次要观察指标为采用牛津膝关节评分评估膝关节功能，以及采用SF-12问卷评估生活质量。在4年的时间里，我们用LISS钢板治疗了15例患者的16例髁上假体周围骨折。11例患者（12处骨折）接受了平均8个月的随访。这12处骨折中的11处平均在3.7个月后实现愈合。9例患者填写了功能结局问卷。为5例患者（6块LISS钢板）的亚组找到了合适的匹配。两组之间在牛津膝关节评分（p = 0.749）或生活质量评分（p = 0.440）方面未发现统计学上的显著差异。我们的数据表明，全膝关节置换术后髁上假体周围股骨骨折采用LISS钢板内固定可取得良好疗效。
