Objective To explore the clinical curative effect of pre cut type perforated patellar needle combined with tension band steel wire internal fixation minimally invasive in the treatment of patellar transverse fracture. Methods A total of 67 cases of patients with patellar transverse fracture were treated with pre cut with holes patellar needles com-bined with tension band wire fixation of minimally invasive, the fracture degree,joint activity,knee functional score and incidence of complications were observed and analysised. Results Postoperative knee function score, the excellent and good rate was 92.5%was significantly higher than the preoperative 9.0%,postoperative knee activity, excellent rate was 90.0% significantly higher than the preoperative 6.0%,postoperative X piece shows the alignment score the excellent rate of 100%was significantly higher than the preoperative 11.0%fractures ,the differences were statistically significant (P<0.05),the incidence of complications of patients was 9.0%. Conclusion Pre cut type perforated patellar needle combined with tension band steel wire internal fixation minimally invasive in the treatment of patellar transverse frac-ture is be conducive to the fracture and recover the function of knee joint,the incidence of complications of patients is low, witch is the practical operation in treatment of patella fracture.
