Abstract
BACKGROUND:High-energy patelar comminuted fracture significantly increased. Single fixation cannot meet the requirement of anatomical repositioning of the patela, multiple-point strong fixation, and early functional exercise. OBJECTIVE:To compare the clinical effect of adjustable patela claws + absorbable suture and Kirschner wire tension band in the repair of comminuted patelar fractures. METHODS: A total of 57 patients with comminuted patela fracture were randomly selected and randomly assigned to two groups. 29 cases received open reduction and adjustable patela claws + absorbable suture fixation. 28 cases received open reduction and Kirschner wire tension band fixation. Operative time, incision length, fracture healing time, postoperative complications and Hospital for Special Surgery knee function scores were compared between the two groups, and then statistical analysis was conducted. RESULTS AND CONCLUSION:No significant difference in incision length and operative time was detected between the adjustable patela claws + absorbable suture group and Kirschner wire tension band group. Significant differences in healing time, incidence of complications and knee function after treatment were observed between the two groups, and above indications were better in the adjustable patela claws + absorbable suture group than in the Kirschner wire tension band group (P < 0.05). These results confirm that compared with the Kirschner wire tension band, adjustable patela claws + absorbable suture in repair of patelar comminuted fracture has some advantages such as short healing time, less postoperative complications, as wel as good functional recovery of knee joint. The fixation is accorded with biomechanical principle of internal fixation, simple to operate, firmly fixed, and has good prospects.关键词
