Prospective Study Comparing Open Reduction Internal Fixation and Distal Femur Replacement for Treating Periprosthetic and Native Distal Femur Fractures in Adults Aged 55 and Older

What this Trial Is About

This research aims to evaluate treatment outcomes for supracondylar femur periprosthetic fractures occurring around a total knee arthroplasty TKA, a serious complication that is becoming more common. These fractures are difficult to fix due to changes in anatomy from the TKA and the presence of a metal femoral component, often leading to high complication rates. The study compares two surgical treatments open reduction and internal fixation ORIF and distal femur replacement total knee arthroplasty DFR, focusing on mobility and knee function outcomes. Participants receive either ORIF or DFR surgery for their distal femur fracture, with each group followed for at least two years. The study measures include the Timed Up and Go Test, which assesses mobility by timing participants as they stand, walk 10 feet, return, and sit, and the KOOS Jr assessment, a questionnaire evaluating knee symptoms, pain, daily activities, sports, and quality of life. These tests are performed at 6 weeks, 3 months, 6 months, 12 months, and 24 months after surgery. During the study, participants will attend scheduled assessments to complete the mobility test and knee function questionnaire at the specified intervals. Researchers will collect data on recovery progress, knee health, and functional abilities over the two-year period. The main outcomes focus on how well patients regain mobility and knee function after either ORIF or DFR treatment. The study is designed to monitor safety and effectiveness of these surgical methods in treating distal femur fractures.
