| Objective To study the feasibility and effect of arthroscopic treatment of Schatzker type III tibial plateau fracture with percutaneous Kirschner wire and interface screw fixation. Methods From May 2008 to January 2018, 20 cases of Schatzker type Ⅲ tibial plateau fractures were treated with Kirschner wire and interface screw fixation in PLA No.910 Hospital. All cases were assisted by arthroscopy, combined with minimally invasive fracture reduction technique, using multiple Kirschner wires combined with interface screw fixation and allograft bone grafting. After operation, the function of knee joint was evaluated by HSS. Results All the 20 patients in this group were followed up for 2-10 years, with an average of (6.7±2.2) years. After operation, all incisions were healed in the first stage, and all fractures achieved osseous healing,and healing time was 2.5-6 months, with an average of 3.1 months,and knee joint activity was 0°-130°. At the last follow-up, the HSS score of knee joint function was excellent in 18 cases, good in 1 case and fair in 1 case,and the excellent and good rate was 95.0%. None of the patients showed deep vein thrombosis, incision infection or knee stiffness. Conclusion Arthroscopic fixation with pickers needle combined with interface screw has the advantages of accurate reduction, small injury and quick healing under direct vision. It can deal with other injuries in the joint cavity in one stage, which is conducive to rapid functional recovery and less complications. |
