Post-operative Oedema Reduction - Hip Replacement

Preventing the build-up of
post-operative oedema in
Total Hip Replacement patients, during and after surgery

Elective and fractured hip patients, particularly those with comorbidities and compromised vasculature, are at greater risk of post-operative complications such as oedema which can impair local tissue perfusion and surgical wound healing1.

The cause:

Impaired calf muscle pump function, the result of immobility and venous insufficiency, can cause ineffective venous return, resulting in the build-up of post-operative oedema which can impede oxygen delivery and surgical wound healing2.

The treatment:

The geko™ device, which enhances muscle pump function to increase blood flow3, decreases the pressure difference between capillaries and the surrounding tissue, and transferring tissue fluid back into the veins and lymph vessels4.

The results from a Randomized Controlled Trail (RCT), comparing the effect of the geko™ device and TED stockings on post-operative oedema in Total Hip Replacement patients, reports the geko™ is more effective than TED Stockings at preventing the build-up of post-operative oedema5.


The geko™ device was worn post-operatively to discharge for 24 hours per day.
