The incidence of periprosthetic knee fractures is steadily increasing, especially in the geriatric population. Surgical treatment in these patients must consider the poor bone quality and the risks of general complications related to age and comorbidities. The aim of the present study is to analyze the clinical and radiographic outcome of internal fixation for periprosthetic knee fractures of the distal femur in elderly patients (>75aa).
All patients treated at the Orthopedic and Traumatology Unit of Cattinara Hospital-ASUGI (Trieste, Italy) between September 2014 and September 2019 for distal femur periprosthetic fracture after total knee replacement were included in the study. Mortality, complications, radiographic healing and functional outcomes were retrospectively evaluated. Data collection was conducted by clinical database searching and telephone interview. Results were compared with the literature.
The study population included 19 patients, F:M 16:3, mean age 84 years. Plate fixation was used in the majority of cases (90%). One-year mortality was 21.05%. Radiographic healing of the fracture occurred in 92% of cases. Nonetheless, 61% of patients saw a worsening in their functional outcome.
Internal fixation is a valuable and safe option for distal femur periprosthetic fracture treatment in the elderly. The significant impact of periprosthetic knee fractures on the medium- to long-term survival and quality of life of the elderly patient is confirmed.
人工膝关节假体周围骨折的发病率稳步上升，尤其是在老年人群中。这些患者的手术治疗必须考虑到较差的骨质量以及与年龄和合并症相关的一般并发症风险。本研究旨在分析高龄 (>75 岁)患者股骨远端假体周围膝关节骨折内固定的临床和影像学结果。
本研究纳入了 2014 年 9 月至 2019 年 9 月期间在意大利的卡蒂纳拉医院-ASUGI（的里雅斯特）骨科和创伤科治疗的所有全膝关节置换术后股骨远端假体周围骨折患者。回顾性评估死亡率、并发症、影像学愈合和功能结果。通过临床数据库检索和电话访谈进行数据收集。结果与文献进行了比较。
研究人群包括 19 名患者，男女比例为 16:3，平均年龄为 84 岁。大多数患者采用钢板固定（90%）。1 年死亡率为 21.05%。92%的病例骨折愈合，但 61%的患者功能预后恶化。
内固定是治疗老年股骨远端假体周围骨折的一种有价值且安全的选择。假体周围膝关节骨折对老年患者的中远期生存和生活质量有显著影响。
