Factors influencing the functional outcomes of tibia plateau fractures after surgical fixation.

Aims: The aim of this study is to assess the functional and radiological outcomes of 52 surgically treated tibial plateau fractures and to determine the factors affecting functional outcomes. Subjects and Methods: A total of 52 patients who were operated between 2007 and 2014 due to tibial plateau fractures were retrospectively reviewed. The Knee Society Score (KSS) was used for the functional outcome assessment. The Kellgren–Lawrence radiological evaluation score was used for the relationship between postoperative trauma and osteoarthritis in the last follow-up. Results: Patients' mean age was 47.7 years (range, 14–84 years). The immobilization period was 4.2 weeks (range, 0–8 weeks), the full weightbearing time was 3.3 months (range, 1.5–5 months), and the follow-up time was 47 months (range, 17–102 months). Patients' mean KSS was 84.3 (range, 40–100). According to the Kellgren–Lawrence classification, 26 patients had grade 0, 11 patients had grade 1, 8 patients had grade 2, 5 patients had grade 3, and 2 patients had grade 4 postoperative osteoarthritis. Conclusion: Use of graft if there is collapse on joint surface, early knee motion, and early started full weightbearing after surgical fixation of tibial plateau fracture is essential for successful outcome. Findings of osteoarthritis on X-rays are not related to poor functional outcome at the mid- to long-term follow-up of surgical treated tibial plateau fractured patients.
