After knee replacement surgery, proper knee elevation is a significant part of post-operative care. This practice helps manage discomfort and supports the body’s natural healing, contributing to a smoother recovery journey.
Achieving Proper Knee Elevation
Lie flat on your back. Use pillows, cushions, or a specialized wedge to support the entire lower leg, from calf to ankle. Ensure your heel is slightly higher than your knee, and your knee is positioned above your heart. This uses gravity to encourage fluid drainage away from the surgical site.
Maintain a relatively straight knee while elevated. Supporting the leg consistently along its length helps prevent strain on the knee joint and surrounding tissues. The height should be sufficient to place the knee higher than the heart.
Mistakes to Avoid
Avoid placing pillows directly under the knee. This can keep the knee bent, potentially leading to stiffness and knee flexion contracture, making it harder to fully straighten the leg. The knee should be as straight as possible during elevation to promote extension.
Another mistake is not elevating the leg to a sufficient height. If the knee is not positioned above the heart, the gravitational benefit for reducing swelling and improving circulation is diminished. Attempting to elevate the knee while sitting in a recliner chair is often ineffective, as the leg may still be lower than the heart. Also, ensure consistent support for the entire lower leg, not just the foot, to prevent discomfort.
How Long and How Often to Elevate
In the initial days and weeks following surgery, frequent elevation is beneficial, especially during the first 3 to 5 days when swelling is most pronounced. Each elevation session should last approximately 20 to 30 minutes. This duration allows for effective fluid drainage.
It is recommended to elevate the knee multiple times throughout the day, particularly after periods of activity or exercise. Balance elevation with gentle movements and prescribed exercises to maintain joint mobility and prevent stiffness. Always follow the specific recommendations provided by your surgeon or physical therapist.
Why Elevation Matters for Recovery
Knee elevation is a fundamental component of post-surgical recovery. Elevating the leg above the heart uses gravity to reduce fluid accumulation, minimizing swelling around the surgical site. This reduction in swelling is linked to a decrease in post-operative pain by alleviating pressure on the knee joint.
Furthermore, elevation promotes improved circulation by encouraging blood flow back to the heart, which helps reduce the risk of blood clots and ensures healing tissues receive ample oxygen and nutrients. These combined effects create a more favorable environment for the body’s natural healing processes, facilitating a more efficient recovery and allowing for better participation in physical therapy.
