Abstract
ObjectiveTo observe the curative effects of Kirschner wire combined with patella concentrator fixation for patella fracture.
MethodsA total of 147 patients with patella fracture who admitted in Kaifeng Central Hospital from March 2017 to January 2019 were selected. All patients underwent open reduction and internal fixation. The 147 patients were divided into 3 groups according to the fixation: group A (51 cases)was treated by Kirschner wire internal fixation; group B (50 cases) was treated by patella concentrator internal fixation; group C (46 cases) was treated by Kirschner wire combined with patella concentrator internal fixation. During 12 months of postoperative follow-up, the surgical indexes and the excellent rate of knee joint recovery at the end of follow-up were compared among the three groups; after 1 week, 2 weeks , 4 weeks of surgery, the visual analogue scale (VAS) was used to evaluate the pain of surgical site of the patients; after 1 week, 2 weeks, 4 weeks and 12 weeks of surgery, the range of motion of flexion of knee joint in each group was detected and compared; the incidence of complications during follow-up was recorded.
ResultsAt the end of follow-up, the excellent rate of knee joint recovery in group C was higher than that in group A and group B (P<0.05); there was no statistical difference between group A and group B (P>0.05); there was no statistical difference in the intraoperative bleeding volume, operation time and fracture healing time among the three groups (P>0.05); there was no statistical difference in the VAS score at each time after surgery between groups (P>0.05); the range of motion of flexion of knee joint in group C at each time after surgery was higher than that in group A and group B (P<0.05); there was no statistical difference between group A and group B (P>0.05); there were no complications in the three groups during follow-up.
ConclusionsUnder the conditions of without prolonging, without prolonging the operation time, increasing the blood loss, the risk of complications and the pain of the operation site, it is more conducive to the recovery of knee joint function and joint flexion than Kirschner wire or patella claw alone, which is safe and reliable.
