The aim of the article is to present the medium-term results of surgical treatment of Schatzker's IV, V, and VI tibial plateau fractures, in a retrospective study of 22 patients at a level-1 trauma center. Twenty-two of 34 patients with Schatzker's IV-VI fractures completed follow-up at a mean of 56 months (range: 7-103 months). Patients' mean age was 47.6 years (range: 18-76 years). Open reduction and internal fixation were performed in 16 patients, while external fixators were used in the remaining six patents. Patients were assessed radiologically for the presence of arthritis using the Kellgren-Lawrence scale. Functional outcomes were measured using the Lysholm's knee score, knee injury, and osteoarthritis outcome score (KOOS). Quality of life was also assessed postoperatively using the EuroQol-5D (EQ-5D) form and EQ-VAS (visual analogue scale) score. There were no postoperative infections and no fracture went on to nonunion. Absence of arthritic change was noted in only 6.3% of cases. The average KOOS score was 80 and the average Lysholm's score was 84.91. Regarding the postoperative quality of life, mobility was impaired in 45.5%, self-care in 27.3%, and usual activities in 36.3% of patients. Pain or discomfort was reported in 77.2% and anxiety or depression in 40.9% of cases. The mean VAS score was 77.8. Eighty percent of patients had returned to their previous activities at the time of last follow-up. Although complex tibial plateau fractures are associated with a high rate of complications and can have a severe impact on the injured knee, most patients had quite satisfactory results during their medium-term clinical evaluation, in our study. It is a Level IV case series study.
