Abstract:Objective To investigate the differences in the clinical efficacy and safety of two kinds of minimally invasive arthroscopic internal fixation including medical wire and Orthocord suture in the treatment of tibial eminence fracture of Meyers-Mckeever type III-IV. Methods One hundred patients with tibial eminence fracture of Meyers-Mckeever type III-IV were chosen in our hospital in the period from June 2011 to June 2015 and randomly divided into control group (50 patients) with minimally invasive arthroscopic internal fixation by medical wire and observation group (50 patients) with minimally invasive arthroscopic internal fixation by Orthocord suture. The operation time, tourniquet application time, fracture healing time, HSS score, Lysholm score, and flexion and extension degree of the knee joint after operation, positive rate of Lachman test and complication incidence were compared between the two groups. Results The operation time of the observation group was significantly shorter than that of the control group (P < 0.05). There was no significant difference in the tourniquet application time or fracture healing time between the two groups (P > 0.05). The HSS score, Lysholm score, and the flexion and extension degree of the knee joint after operation in the observation group were significantly better than those in the control group (P < 0.05). There was no significant difference in the positive rate of Lachman test or the complication incidence between the two groups (P > 0.05). Conclusions Compared with minimally invasive arthroscopic internal fixation by medical wire, minimally invasive arthroscopic internal fixation by Orthocord suture can efficiently shorten the operation time, improve the joint function recovery after operation but does not increase the complication incidence in the treatment of tibial eminence fracture of Meyers-Mckeever type III-IV.
