Abstract: Objective To investigate the clinical effect of patella steel plate and gram needle tension band fixation on patella fracture.
Methods The study subjects were 67 patients with eligible patella fractures admitted in the hospital from January 2015 to October 2020.After excluding the late follow-up of the lost patients,30 cases each of the steel plate group and the tension band group were selected to facilitate the statistical comparison.Among them,the steel plate group is a patella steel plate,the tension band group is a modified gram needle titanium cable tension band.The operation time,bleeding volume,incidence of complications and the function of the knee joint were analyzed and evaluated.
Results Operation time,steel plate group(63.53±7.07) min,tension band group(76.53±4.16)min.Cut-out length,steel plate group(6.28±0.57)cm,tension band group(7.73±0.77)cm.The knee activity was measured 6 months after surgery,steel plate group(124.07±4.35),tension band group(118.40 ± 4.55).Surgical bleeding volume,steel plate group(118.42±10.39)ml,tension band group(133.77±12.43)ml.The relative statistical comparison differences between the two groups have statistical significance(P<0.05).
Conclusion Compared with the steel plate group and the tension band group,t he operation time was shortened,and the incision length was also overall shorter than the tension band group;and the satisfaction of postoperative knee activity in the steel plate group was also stronger than that of the tension band group.The treatment of patella fracture has good biomechanical stability and is significantly better than that of tension-band fixation.Worth the promotion in the clinical work.
