| Abstract:Objective: To observe the accuracy of 3D printing patient-specific instrumentation (PSI) guider assisted high tibial osteotomy (HTO) in the treatment of varus knee osteoarthritis.Methods: From May 2018 to December 2019, 15 patients with varus knee osteoarthritis were treated with 3D printing PSI guider assisted medial opening wedge high tibial osteotomy. The preoperative medial proximal tibial angle (MPTA), weight bearing line (WBL) point, distraction height, posterior tibial slope (PTS), and joint line convergence angle (JLCA) were simulated and measured by CT three-dimensional reconstruction, which were compared with the actual measurement value after osteotomy.Results: There was no significant difference between the preoperative and postoperative measurement of MPTA, WBL point, distraction height, PTS and JLCA, which were consistent. All patients' wounds were healed in the first stage without complications.Conclusions: 3D printing PSI guider assisted HTO can enhance accuracy in correcting lower limb alignment, reduce the risk of changes in PTS, JLCA, etc and improve the curative effect. |
