Abstract Objective To observe the application effect of three-dimensional strapping reduction technique in thepatellar fracture surgery. Methods 110 patients with patellar fractures were selected as the study subjects andrandomly divided into two groups, each with 55 cases. The traditional open reduction and internal fixation treatmentwas received by the patients in the conventional group, while three-dimensional srapping reduction technique as anauxiliary treatment was received by the patients in the experimental group. The treatment and rehabilitation status,postoperative complications, gait evaluation, and knee joint function recovery were compared between the two groupspatients. Results The intraoperative fluoroscopy time, intraoperative blood loss, surgical time, hospital stay, andfracture healing time in the experimental group were significantly lower than those in the control group, showing a statistically significant difference ( P<0.05 ). 'The incidence of postoperative complications in the experimental groupwas significantly lower than that in the control group ( P<0.05 ). The postoperative step length, pace, and frequencyin the experimental group were significantly higher than those in the conventional group ( P<0.05 ). The HSS andLysholm seores in the experimental group were significantly higher than those in the control group at 1, 3 and 6 months after surgery( P < 0. 05 ). Conclusion The three-dimensional strapping reduction technique has highapplication value in the open reduction and internal fixation of patellar fractures. It has a positive significance inreducing bleeding,reducing the risk of surgicashortening intraoperative fluoroscopy and surgical time,complications, and promoting the recovery of patient gait and knee joint function.
