Personalized Weight-Bearing With Smart Crutch Tips After Surgery for Tibial Plateau Fractures

This study will compare two approaches to rehabilitation after surgery for a fracture of the upper part of the shinbone that involves the knee joint (tibial plateau fracture). The main question is whether a personalized plan for putting weight on the injured leg, combined with feedback from smart crutch tips, helps patients return to walking without assistance sooner than usual care, without increasing complications. Participants will be assigned by chance to one of two groups: * Personalized rehabilitation: Researchers will use CT and MRI scans taken after surgery to create a computer model of the repaired bone and estimate how it responds to different loads. The treating doctor will use this information, together with the patient\'s clinical condition, to prescribe how much weight the patient may place on the injured leg. Smart Crutch Tips will provide feedback to help the patient follow this prescription. * Usual care: The treating doctor will prescribe weight-bearing according to usual clinical practice. Participants will also use Smart Crutch Tips, but the devices will record information without showing the patient loading data, step counts, or related alerts. Researchers will compare how long it takes participants to walk independently without crutches, a cane, or another walking aid. They will also assess bone healing, knee function, pain, swelling, fear of movement, adherence to weight-bearing instructions, and complications. Participants will attend follow-up visits and complete assessments of their recovery. Imaging specialists who do not know which treatment group participants are in will assess fracture healing and whether the repaired bone has remained in position.
