Abstract
Background: Fracture of the tibial plateau represents approximately 8% of fractures in elderly patients. These injuries occur with an estimated incidence of 13.3 per 100,000 adults annually, with nearly a quarter of these occurring in elderly patients with concomitant osteoporosis. In young patients, the mainstay treatment for displaced tibial plateau fracture is open reduction and internal fixation (ORIF). However, in elderly patients with periarticular fracture, the combination of poor bone quality, metaphyseal bone comminution, and friable soft tissue envelope creates unique challenges to traditional ORIF.
Aim of the Work: To evaluate the perioperative complication rates and clinical outcomes in patients following TKA for primary treatment of tibial plateau fracture and to establish whether TKA can be considered a reliable primary treatment option in selected individuals.
Patients and Methods: The present systematic review will be performed in accordance with the preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive search for all level I–IV evidence published articles using the online databases MEDLINE, Embase, and PubMed will be performed. The purpose of this search is to identify all eligible studies featuring perioperative complications or clinical outcomes in patients following TKA for primary treatment of tibial plateau fracture.
Results: The immediate management of acute tibial plateau fracture in elderly patients continues to be controversial. Although there is emerging evidence showing positive results for primary TKA for tibial plateau fracture, it is paramount to appreciate that performing TKA in the context of acute tibial plateau fracture is not a straightforward attempt. Many of these patients have notable loss of the articular surface, which disrupts normal anatomic references, and compromised soft tissue due to possible coexisting ligamentous injury.
Conclusion: Total knee arthroplasty for treatment of acute tibial plateau fracture is an enticing alternative to ORIF to allow early weight bearing, especially in elderly patients with poor bone quality and a friable soft tissue envelope. Our systematic review shows that functional scores are only average.
