- Abstract
- Background: The aim of this study is to investigate complications following medial opening-wedge high tibial osteotomy using a locking plate. In addition, we aimed to compare postoperative outcomes between the complicated and the uncomplicated group. Methods: This study enrolled 209 patients who underwent medial opening-wedge high tibial osteotomy between 2010 and 2015. Patients with a follow-up period of at least 2 years were enrolled. Medical records and radiologic data were retrospectively reviewed. The complications were assessed up to postoperative 2 years and categorized into major and minor complications. The preoperative and postoperative clinical statuses were assessed using the Western Ontario McMaster University Osteoarthritis Index. Results: The mean patient age was 56.4 +/- 5.9 years. Overall complication rate was 29.7%. Minor complications included undisplaced lateral hinge fracture (12.0%), hardware irritation (1.4%), displaced lateral hinge fracture (2.4%), delayed wound healing (1.9%), undisplaced lateral tibial plateau fracture (1%), and superficial wound infection (1%). Major complications were symptomatic hardware which needed hardware removal (4.8%), deep wound infection (1.9%), hardware failure with correction loss (1%), nonunion (0.5%), and early conversion to arthroplasty (0.5%). Most complications occurred intraoperatively (30.6%) and within 3 months postoperatively (40.3%). The major complication group showed a statistically higher Western Ontario McMaster University Osteoarthritis Index score than did other groups at postoperative 1 year (P = .013) and 2 years (P = .001). Conclusion: The overall complication rate was 29.7%. Most complications were minor. The most common complication was undisplaced lateral hinge fracture. Major complications occurred in 8.6%. The major complication group showed significantly worse clinical outcomes than did the uncomplicated and minor complication groups. (C) 2018 Elsevier Inc. All rights reserved.
