The clinical research of modified split patella for patellar fracture

Objective To assess the clinical efficacy of modified split patella in the treatment of patellar fracture. Methods 56 patients with patellar fracture were selected, and they were divided into two groups according to the random number method.The regular group was treated with common split patella, while the improved group was treated with modified split patella.In both two groups, the aspects of split patella slip, model large and knee pain were recorded. Results The incidence rates of model large and knee pain in the improved group were 3.57%, 7.14%, which were 25.00%, 32.14% in the regular group, the differences were statistically significant(χ2=5.250, 5.543, P=0.022, 0.019). The incidence rate of split patella slip in the regular group was 3.57%, that was 0.00% in the improved group, the difference was statistically significant(χ2=1.018, P=0.313). Conclusion Modified split patella minimizes the incidence of split patella model large and patellofemoral osteoarthritis.Thus, it deserves further application.
