The Cambridge Experience With Tibial Plateau Fractures in Older Adults: A Case Series

Complex tibial plateau fractures (TPFs) represent a significant treatment challenge for any Orthopaedic surgeon. Current literature suggests that significantly displaced TPFs in the elderly require operative fixation, an operation that is associated with serious complications including septic and post-operative arthritis. As a result, these patients are five times more likely to require a total knee replacement (TKR). We present a case series of five elderly patients with complex TPFs who made serendipitous recoveries while awaiting operations. Their fractures were deemed so severe that they were being considered for TKR instead of fixation. We discovered their surprising functional improvements while they were being reviewed pre-operatively and decided to delay operating. We are currently unaware of any cases in the literature that have reported such findings. In total, five patients presented in 2019 with closed, varus/valgus stable fractures. They were managed non-operatively in hinged-knee braces, progressively weight-bearing with a minimum follow-up of 10 months. Oxford Knee Scores (OKS) were recorded at zero and four months after their injury. All patients were female with an average age of 69 years. Average fracture depression - 8.48mm, average fracture split - 8.66mm, average OKS reduction - 19%. All patients were able to mobilise independently at four months follow-up. Our results suggest that non-operative management can be considered as primary management in elderly patients with significantly displaced TPFs. Should this fail, or they develop arthritis, a TKR can be performed. This carries two benefits: the patient avoids the significant complications associated with fixation and should a TKR be required, it can more easily be performed in a patient without metalwork in-situ. We feel that the results from this case series might offer insight into a new treatment strategy and continue to closely follow these patients.
