Morbidity and Mortality After Surgical Management of Tibial Plateau Fractures in Octogenarians

Background: Because the geriatric population continues to increase in number, the incidence of geriatric tibial plateau fractures in octogenarians is projected to increase. The functional and physiological status varies within this population. The purpose of this study was to compare the complications after surgical management of tibial plateau fractures in patients aged 65 to 79 years with those in patients aged 80 to 89 years. Methods: In this retrospective cohort study, data were collected from the National Surgical Quality Improvement Program database for the years 2006 to 2018. The Current Procedural Terminology codes and International Classification of Diseases codes were used to identify all tibial plateau fractures that were treated with open reduction and internal fixation. Patients were divided into two groups: 65- to 79-year-old group and 80- to 89-year-old group. Primary and secondary outcomes were studied and included the 30-day mortality. Univariate and multivariate analyses were done with a statistical significance set at P < 0.05. Results: In total, 718 patients with tibial plateau fractures who underwent open reduction and internal fixation were included in this study. Of these, 612 were aged 65 to 79 years, and 106 were aged 80 to 89 years. On multivariate analysis, patients aged 80 to 89 years were at increased risk of postoperative anemia requiring transfusion (odds ratio 2.83; 95% confidence interval 1.37 to 5.84; P = 0.005) and extended length of hospital stay (odds ratio 2.72; 95% confidence interval 1.64 to 4.51; P < 0.001) in comparison with patients aged 65 to 79 years. Conclusion: In appropriately selected octogenarian patients, surgical management of tibial plateau fractures was associated with greater risks of transfusion and longer hospital stay. However, comparisons of the rates of late complications and reoperations remain unknown.

Automated summary

This study compared the complications after surgical management of tibial plateau fractures between patients aged 65 to 79 years and those aged 80 to 89 years. Results showed that patients aged 80 to 89 years had increased risks of postoperative anemia requiring transfusion and extended length of hospital stay compared to patients aged 65 to 79 years.
