Randomized Trial Comparing Patella Anatomical Locking Plate and Tension Band Wiring for Treating Unstable Patellar Fractures

What this Trial Is About

Researchers are evaluating and comparing two surgical methods for treating patellar fractures the patella anatomical locking plate fixation and tension band wiring. This trial aims to assess the effectiveness and safety of these two approaches in patients with unstable patellar fractures. Patellar fractures can cause significant pain and disability, and while tension band wiring is a common treatment, it has drawbacks such as implant prominence and higher reoperation rates. The study involves two groups one receiving fracture repair surgery using an anterior locking plate and screw construct called the patella anatomical locking plate, and the other undergoing open anatomical reduction with a tension band wire construct. The plate fixation uses a low-profile design that may reduce scarring and implant prominence compared to tension band wiring. This is a randomized controlled trial with double masking to compare these two surgical treatments. Participants will be followed with patient-reported functional outcome scores including the Knee Injury and Osteoarthritis Outcome Score KOOS, Tegner Lysholm Knee Score, and Tegner Activity Scale at 2 weeks, 6 weeks, 12 weeks, 6 months, and 12 months after surgery. Additional assessments include radiographic imaging, complication rates, and implant impingement questionnaires at the same timepoints. The study is sponsored by The University of Hong Kong and aims to provide detailed safety and efficacy data over a one-year follow-up period.
