Early ambulation with support is the most effective way to reduce the risk of deep vein thrombosis after total hip arthroplasty. After hip surgery, blood tends to pool in the deep veins due to limited movement, and the operation itself creates a pro-thrombotic state. Getting the patient up and moving with assistance enhances the calf muscle pump, increases venous return, and lessens venous stasis, which directly lowers the chance of clot formation.

Staying in bed keeps the veins sluggish and increases DVT risk. Leg massage isn’t a proven preventive measure for DVT and can be unsafe if a clot is present. A high-protein diet supports general nutrition but does not address the circulatory stasis or clotting risk associated with postoperative immobility.
