Abstract:
Objective To compare the clinical effects of improved rivet double pulley fixation method and traditional Kirschner wire tension band in the treatment of patellar lower pole fractures.Methods 78 patients with patellar inferior pole fractures who underwent surgery in our department between January 2020 and January 2024 and met the inclusion criteria were collected.Divided into two groups according to different fixing methods,the observation group(39 cases)were fixed by modified rivet double pulley,the control group(39 cases)were fixed by steel wire tension band.The operation time,hospital stay,medical expenses,knee motion of the two groups at 1.5 months,3 months and 6 months after surgery,and knee lyshom function score at 3 months and 6 months after surgery were compared between the two groups.Results The observation group had a surgery time of(62.58±6.37)minutes compared to the control group[(60.20±11.18)minutes],and the observation group had a hospital stay of(6.45±1.35)days compared to the control group[(6.40±1.30)days].There was no significant difference in surgical time and hospitalization time between the two group(P＞0.05).The total medical expenses of the observation group were significantly lower than those of the control group(P＜0.05).Knee joint activity in observation group was higher than that in control group at 1.5 months,3 months and 6 months after surgery(P＜0.05),and knee lyshom function scores in observation group at 3 months and 6 months after surgery were significantly higher than those in control group(P＜0.0 5).Conclusion Compared with Kirschner wire tension band fixation for the treatment of patellar lower pole fractures,the improved riveting double pulley surgery does not require secondary surgery to remove internal fixation,resulting in lower overall medical costs,better postoperative knee joint mobility,and better postoperative knee joint function scores.The improved riveting double pulley surgery has more advantages in treating patellar lower pole fractures compared to traditional Kirschner wire tension band fixation.
