Background: A tibial tubercle osteotomy (TTO) is a commonly performed procedure in young and active patients with patellofemoral complaints. Previous small patient series demonstrated a relatively high risk of complications, which appear to be technique dependent. The purpose of this large case series is to quantify the risk of procedure specific postoperative complications related to a uniform self-centering TTO technique in a large cohort, performed by two different surgeons in one center. Hypothesis: We hypothesize that non-union or fracture occurs in less than 1% of the procedures. Patients and methods: Five hundred and twenty-nine knees in four hundred and forty-seven patients who underwent a self-centering TTO with at least one year of follow-up were included. We performed a retrospective cohort review. Tibial fracture, osteotomy non-union, neurovascular complications, infection and wound complications that required surgical intervention were defined as major complications, miscellaneous complications were defined minor. Results: The major finding in this study is the low incidence of non-union (0.6%) and tibial fracture (0.4%). In total 9 (1.7%) major complications were reported. Minor complications included superficial wound infection in five patients, two patients had a venous thrombo-embolism (VTE). Conclusion: A self-centering TTO is a relatively safe technique with a low number of non-union and fracture. (C) 2020 Elsevier Masson SAS. All rights reserved.
