What this Trial Is About
The goal of this clinical trial is to learn whether personalized weight-bearing prescriptions using Smart Crutch Tips™ can improve recovery after surgery for extra-articular proximal tibia fractures. The study will also assess how safe and practical this approach is in daily outpatient use. Can a personalized weight-bearing program based on CT and finite element analysis help the fracture heal faster? Can it help patients return to full weight-bearing sooner? Can it reduce the fear of movement during recovery? Researchers will compare standard rehabilitation, AO Foundation-based recommendations, and personalized weight-bearing programs derived from finite element analysis (FEA) to determine which approach leads to faster healing, earlier mobility, and better outcomes. Participants will: Use Smart Crutch Tips™ during walking for up to 24 weeks; Follow a personalized weight-bearing prescription based on CT scans and biomechanical modeling; Follow a specific walking plan with real-time audio and visual feedback; Attend eight follow-up visits over 36 weeks for clinical exams, x-rays, and CT scans; Complete online questionnaires about pain, activity, and fear of movement.
