Why is knee flexion avoided after a hysterectomy?

Knee flexion is often avoided after a hysterectomy primarily because it can heighten the chance of thrombophlebitis, which is the inflammation of a vein often associated with blood clots. After surgical procedures such as a hysterectomy, patients are at an increased risk for venous thromboembolism (VTE), particularly deep vein thrombosis (DVT). The position of the knees can impact blood flow, and excessive flexion can hinder circulation in the lower extremities.

Maintaining a straight or extended knee position promotes better venous return and minimizes the pooling of blood in the lower legs, which is crucial during the post-operative phase when physical activity is limited. This step is vital in preventing the development of thrombosis, which can lead to serious complications if a clot dislodges and travels to the lungs, causing a pulmonary embolism.

The other options may not be as directly connected to the primary concern of thrombosis following hysterectomy and are less significant in terms of immediate post-operative care. By focusing on avoiding knee flexion, healthcare providers aim to ensure the best possible recovery while reducing risks associated with limited mobility.
