Abstract Background Tibial shaft fractures are the most common long bone fractures requiring treatment. High-energy trauma often causes tibia bone injuries, causing severe complications and long-term disability due to inadequate soft tissue coverage. Tibial shaft fractures can be treated using casts, external fixators, plating, or intramedullary nails. Intramural nailing leads to faster union and reduced complications like malunion and shortening. However, patients often report subjective and objective difficulties after Surgical Instrument generation network (SIGN) nail fixation, affecting knee range of motion, quality of life, and sport activities. Tibial nails and plates are associated with increased knee pain, which negatively affects functional outcomes. No study has been conducted in a poor resource setting like Ethiopia. This study aims to assess functional outcomes of the knee and associated factors after intramedullary nailing of Tibial Diaphysial Fractures at AaBET hospital in Ethiopia. Methods A retrospective health facility based cross-sectional study was conducted on functional outcomes of the knee and associated factors after intramedullary nailing of tibial diaphysial fractures done at AaBET hospital. A medical record review form and a structured questionnaire from patient chart and SIGN nail database collected data. The study was conducted on 151 patients registered on the SIGN nail database using a simple random sampling. Knee injury and Osteoarthritis Outcome Score (KOOS) was used to assess the knee functional outcome. Descriptive statistics such as frequency and percentage were used to summarize the results and binary logistic regression was used to describe the association between variables. P value
