This study hypothesises that the geko™ device is more efficient than TEDS in preventing the formation of symptomatic/asymptomatic Deep Vein Thrombosis (DVTs), post-surgery.

Condition Intervention
Deep Vein Thrombosis
Device: geko™ post-surgery for 48hrs then 4hrs/day until discharge.
Device: TEDS post-surgery for 48hrs then 4hrs/day until discharge.

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: No masking
Primary Purpose: Prevention
Official Title: A Multicentre Randomised Controlled Trial Comparing the Incidence of Asymptomatic and Symptomatic Deep Vein Thrombosis Between the gekoTM Device and Thromboembolism Deterrent Stockings in Patients Recovering From Total Hip Replacement Surgery
