Outcomes after operative treatment of patella fractures

Introduction Patella fractures account for one percent of all fractures. Arthritis, non-union and other complications which affect the function of the lower limb may develop in the long term. The aim was to develop the most optimal osteosynthesis techniques for patella fractures. Methods We analyzed long-term treatment results of 78 patients with patella fractures treated from 2017 to 2018 using the KOOS (The Knee Injury and Osteoarthritis Outcome Score) scale, clinical examinations and knee joint X-rays. Based on the methods of surgical treatment for patella fractures, we divided the patients into 5 groups: Weber tension band wiring for two-fragment fractures; cross-like osteosynthesis and other methods of patella osteosynthesis using K-wires and wire loops for multifragmental fractures of the patella; combined osteosynthesis (tension band wiring with an additional screw or cerclage around patella); partial patellectomy and the inferior pole osteosynthesis. Results A comparative analysis of patients’ groups after surgical treatment of patella fractures using the KOOS scale showed the best results after Weber tension band wiring for transversal fractures (72 %)...
