Outcomes after ORIF are similar in young and elderly patients with tibial plateau fractures: A minimum 2-year follow-up study.

BACKGROUND

This study aimed to compare the outcomes of open reduction internal fixation in young and elderly patients with tibial plateau fractures.

METHODS

A total of 224 patients with tibial plateau fractures treated with open reduction internal fixation at a level I trauma center from 2014 to 2019 were reviewed. The patients with a minimum follow-up of 2 years were divided into two groups, with those aged 60 years and older divided into the elderly group and those under 60 years divided into the young group. The mean follow-up time was 55 months (range: 24-80), and the primary outcomes were quality of reduction and function. The secondary outcomes included complications, fracture healing time, and conversion to total knee arthroplasty.

RESULTS

The elderly group had a higher proportion of women than the young group (61.1% vs. 23.9%, p < 0.001). Diabetes was more prevalent in the elderly cohort than in the young cohort (18.9% vs. 9.0%, p = 0.030). The rate of bone grafts was higher in the elderly group (57.8% vs. 41.8%, p = 0.019), but no significant differences were found between the groups regarding fracture characteristics, the operative time or intraoperative blood loss. The reduction quality, knee function, postoperative complications, healing time, and total knee arthroplasty conversion rate were not significantly different (p > 0.05) between the groups.

CONCLUSIONS

Open reduction internal fixation remains a satisfactory technique to treat tibial plateau fractures in the elderly. Although the rate of bone grafts is higher in elderly patients, they had comparable outcomes compared with their younger counterparts.
