We have developed a novel surgical technique using locking compression miniplates in treatment of multifragmentary, comminuted patellar fracture.
We retrospectively reviewed the medical and radiologic records of patients who were surgically treated with locking compression miniplates for patellar fracture from June 2018 to November 2011. Primary outcome was bone union, and secondary outcomes were postoperative complications associated with procedure. Functional outcomes included Lysholm scores and range of motion.
A total of 20 patients with AO/OTA 23-C 2 and 3 patellar fracture were followed up for an average of 15 months (range: 11~18). Average patient age was 57.15, and 11 male and 9 female patients were included. All patients presented AO-OTA 34-C2 or 3 patellar fracture. Primary fracture union healing was seen in 19 out of 20 patients (95%), and an average time to bone union was 15.6 weeks (range 10~40). There were no fixation failure or postoperative infection. All of the patients achieved the postoperative average ROM of 120 degrees, and the mean Lysholm score at the final follow-up was 90.4
Multiple interfragmentary fixation with miniplates is a versatile, low-profile, and effective surgical technique for comminuted patella fracture.
