Abstract: Objective To investigate the effect of using Kirschner wire tension band plus titanium cable ring tie on the limb function and short-term efficacy of patients with complex patella fracture.Methods A total of 100 patients who underwent patella fracture surgery from December 2018 to December 2020 were selected and divided into the observation group and the control group,50 patients in each group according to the treatment method.The observation group was treated with Kirschner wire tension band plus titanium cable ring ligating,and the control group was treated with Kirschner wire tension band.The surgical conditions of the two groups were compared.Fracture healing;Excellent rate of joint function;The incidence of complications,pain score and satisfaction were compared between the two groups.Results The average postoperative length of hospital stay in the observation group was(8.62±2.69) d,shorter than the (10.54±3.54) d in the control group,and the average pain score was (2.51±0.24) points,which was less than the (5.52±0.72) points(P<0.05) in the control group.The average fracture healing time in the observation group was (10.74±1.58) weeks,which was shorter than that of the control group at (13.54±2.69) weeks,and the overall good rate of fracture healing was 88.00%,which was higher than that of the control group of 60.00%(P<0.05).The excellent rate of joint function in the observation group was 92.00%,which was higher than that of the control group(P<0.05).The complication rate in the observation group was 4.00%,lower than the 20.00(P<0.05) in the control group.The total satisfaction rate of the observation group was 86.00%,which was higher than that of the control group of 72.00%(P<0.05).Conclusion Kirschner wire tension band plus titanium cable ring ligating is effective in the treatment of complex patella fracture,which can improve the limb function of patients with less complications.
