Abstract:Objective To investigate the clinical effect of minimally invasive headless compression screw fixation in the treatment of transverse patellar fracture. Methods A total of 80 patients with transverse patellar fracture who received treatment from March 2015 to February 2017 were selected and divided into control group and observation group randomly (n=40, each).The control group patients received minimally invasive surgery of hollow screw and tension band, and the observation group patients received minimally invasive headless compression screw fixation.The operation related indexes (such as operation time, intraoperative bleeding volume, fracture healing time), knee joint activity score (Lysholm score), visual analogue scale (VAS), incidence of complications and recurrence rate were observed. Results Compared with control group, the operation time, fracture healing time and intraoperative bleeding volume were fewer in observation group [(63.32±4.28)min vs (77.08±5.12)min, t=13.041, P<0.05; (68.09±12.21)d vs (121.61±21.95)d, t=13.476, P<0.01; (30.59±7.04)ml vs (112.29±11.79)ml, t=37.629, P<0.01].There were no significant differences in Lysholm socre and VAS before the treatment between two groups (P>0.05).After the surgery, the Lysholm socre was higher and VAS was lower in both group, and the Lysholm socre was higher and VAS was lower in observation group than those in control group (P<0.05).The total incidence of complications and 1-year recurrence rate in the observation group were 25.00% and 2.50% lower than those in the control group (50.00% and 22.50%, P<0.05, P<0.01). Conclusion Minimally invasive headless compression screw fixation has a better clinical effect than hollow screw and tension band in the treatment of transverse patellar fracture, which could not only effectively shorten the operation and fracture healing time, reduce intraoperative bleeding, but also improve the prognosis of patients and relieve pain.
