Impact of Krachow sutures combined with discontinuous vertical wire fixation in elderly patients with a comminuted fracture of the inferior pole of the patella
Objective The objective was to investigate the effects of Krachow sutures combined with discontinuous vertical wire suture fixation on knee range of motion(ROM)and the Bostman score in elderly patients with a comminuted fracture of the inferior pole of the patella.Methods A total of 102 elderly patients with a comminuted fracture of the inferior pole of the patella treated in our hospital from January 2019 to March 2022 were selected as the study subjects.They were divided into two groups according to the random number table method.The observation group(51 cases)was treated using Krachow sutures combined with discontinuous vertical steel wire sutures,and the control group(51 cases)was treated using discontinuous vertical steel wire sutures.The clinical efficacy,knee ROM,knee function Bostman score,and complications of the two groups were statistically analyzed.Results The observation group showed an excellent rate of 88.24%,and the control group had an excellent rate of 64.71%.The difference was statistically significant(χ2=7.173,P=0.009).The knee ROM and Bostman score of the observation group were 131.51°±6.80° and 28.65±2.20 points,respectively,while the knee ROM and Bostman score of the control group were 115.87°±5.91° and 23.58±2.51 points,respectively.The differences were statistically significant(t=9.043;10.346,P＜0.001).The total incidence of complications was 9.80%in the observation group and 27.45%in the control group;the difference was statistically significant(χ2=5.332,P=0.042).Conclusions Krachow sutures combined with discontinuous vertical steel wire sutures for treating elderly patients with a comminuted fracture of the inferior pole of the patella had good reduction,stable fixation,little influence on the surrounding soft tissue,few complications,and were conducive to the recovery of knee joint function.
