Outcomes of Tibial Plateau Fracture Surgical Fixation: a Comparative Study Between Younger and Older Age Groups

Tibial plateau fractures account for approximately 8% of the fractures of the elderly. Low bone quality that is more common in the elderly is one of the major challenges in fixing fractures and may be a barrier to achieving satisfactory outcomes after a surgical fracture treatment. Accordingly, surgical fixation of tibial plateau fractures was controversial in the elderly. This study aimed to investigate and compare the clinical outcomes of surgical fixation in patients over and under 60 years of age. This study was conducted as a retrospective cohort study of data that were prospectively collected. In total, 48 patients who underwent surgery with open reduction and internal fixation before August 2019 were recruited and followed up at least one year after surgery. Demographic characteristics, the range of motion of the knees, visual analog scale (VAS) score of pain intensity, and the Oxford Knee Score (OKS) were obtained in this study. Furthermore, Short Form-36 (SF-36) questionnaire was used to evaluate patient satisfaction. In total, 19 and 29 patients were over and under 60 years of age, respectively. According to Schatzker’s classification, the most common type of fracture was type VI. The range of motion in the knees did not differ significantly between the two groups (P>0.05). Moreover, OKS and the VAS of pain intensity were not significantly different in both groups (P>0.05). In addition, SF-36 scores were not significantly different between elderly patients and the age-matched general population. However, younger patients had lower scores in the physical function and vitality scales of SF-36, compared to the age-matched general population. Based on the results of the present study, it can be stated that increasing age did not affect the surgical outcomes of patients with tibial plateau fractures. Level of evidence: III
