This prospective cohort study aims to evaluate the clinical efficacy of high-strength suture modified tension band fixation in treating patellar fractures and compare it with traditional screw-cable tension band fixation. Adult patients (18-55 years) with AO/OTA 34-C1 or 34-C2 patellar fractures will be enrolled and followed for 12 months. Primary outcomes include Lysholm knee function score, knee range of motion (ROM), and visual analog scale (VAS) pain score at 12 months post-surgery. Secondary outcomes include fracture healing time, radiographic alignment quality, complication rates, reoperation rates, implant removal rates, SF-36 health survey scores, and patient satisfaction. No additional biological samples will be collected; data will focus on clinical, radiographic, and follow-up information.
