Abstract:
Objective To describe a technique of closed reduction and percutaneous internal fixation for the treatment of displaced patellar fractures and evaluate the clinical results. Methods Fifteen cases (nine males and six females with mean age of 35.5 years, ranging from 24 to 65 years) with displaced patellar fractures were treated with closed reduction (or an arthroscopic-assisted reduction) and percutaneous cannulated screw fixation (or Kirschner wire tension band wiring technique) under guidance of fluoroscopy or C-arm X-ray tomography. Controlled passive range of motion exercises started on the first postoperative day. The mean follow-up was 28 months (24-35 months). Results All cases healed successfully with healing time of (1.2?2.2) months and mean Lysholm II score of 86.8 (79-96), except for one patient regained full knee range of motion. Compared with the contralateral side, a mean quadriceps atrophy of 0.8 cm was seen in unilateral cases based on Tandogan measurement. There was no implant failure or postoperative infection. Conclusions The technique of closed reduction and percutaneous internal fixation is appropriate for displaced, transverse, longitudinal or oblique patellar fractures and can facilitate early postoperative range of motion exercises and accelerate rehabilitation of the affected knee with few complications and minor incision without disturbing blood supply of the patella. But, this method is not suitable for severely comminuted fractures.
