27year survival of Maney Watt unicondylar hemi knee replacement for fixation of a lateral tibial plateau fracture — a case report

We report the case of a 62-year-old gentleman who underwent a novel treatment for a lateral tibial plateau fracture 27 years ago. The patient presented to an elective knee outpatient clinic with new onset knee pain.

Further investigation revealed that this was a Maney Watt prosthesis (Zimmer UK) for use in the management of unicompartmental osteoarthritis. This mode of fixation gave this patient over 20 years of good functional outcome. Following revision, the patient was followed up at 5 years, reporting a satisfactory outcome.
