What this Trial Is About
Researchers are evaluating the clinical effectiveness of a high-strength suture modified tension band fixation in treating patellar fractures compared to the traditional screw-cable tension band fixation. This prospective cohort study focuses on adult patients aged 18 to 55 years with specific types of patellar fractures (AO/OTA 34-C1 or 34-C2). The study aims to assess knee function, pain, and motion after surgery, as well as secondary outcomes like healing time, complications, and patient satisfaction over a 12-month follow-up period. Patients admitted for patellar fracture surgery will be assigned to one of two groups based on the surgical method used: the high-strength suture fixation group or the traditional screw-cable tension band group. Both procedures involve surgery to repair the fracture, with the study comparing outcomes such as surgical time, blood loss, hospital stay, and complication rates. Follow-up visits include clinical assessments and imaging to monitor healing and alignment. Participants will undergo evaluations including knee function scores, range of motion measurements, pain scales, muscle strength testing, and patient satisfaction surveys at multiple timepoints up to 12 months after surgery. Data collected covers demographics, fracture details, comorbidities, and perioperative information. Adverse events will be recorded and managed. The research team will analyze the data to compare the two fixation methods and publish the results.
