Tension band fixation for treatment of patellar fracture: novel technique using a braided polyblend sutures and ring pins.

Abstract

To evaluate a new tension band fixation technique for patellar fracture using braided polyblend sutures (PBSs) and ring pins (RPs). A total of 13 patients (average: 58.2 years) with transverse or comminuted patellar fractures were treated by this technique. From the 4th week after the surgery, normal activities of daily living were permissible. Bone union was achieved at a mean 3 months from surgery, without any cases of failure, redislocation or postoperative complication. At 12 months after surgery, mean Lysholm score was 93.6, knee motion was extension 0.8 degrees to flexion of 134.6 degrees and visual analogue pain score was 0.5. The new tension band fixation technique using braided polyblend sutures resulted in good outcomes and is considered clinically effective for patellar fracture reduction.
