Recovering from a knee replacement takes time, consistency, and care, but the right exercises can make all the difference in building strength, reducing stiffness, and helping you return to everyday activities with confidence. Low-impact movement is especially important during recovery, providing the benefits of physical activity without overloading your new joint.
Below, we’ll explore some of the best low-impact exercises to support your recovery journey, plus when and how to get started.
Why Low-Impact Movement Matters After Surgery
After knee replacement surgery, it’s essential to keep pressure on the joint light and controlled. Low-impact exercises help improve circulation, reduce scar tissue, and increase flexibility without risking damage or inflammation. These types of activities also help rebuild muscle strength around the joint to provide better support and function long-term.
For most patients, recovery exercises begin within a few days of surgery under the supervision of a physical therapist. However, continuing movement and progressing it appropriately, at home, is a key part of regaining mobility and independence.
Best Low-Impact Exercises to Try
1. Seated Leg Extensions
While sitting in a sturdy chair, straighten one leg at a time and hold for a few seconds before lowering it. This simple exercise helps strengthen the quadriceps and maintain range of motion.
2. Ankle Pumps and Circles
Lying down or seated, point and flex your toes repeatedly to activate the calf muscles. Circling your ankles in both directions also promotes circulation, which helps reduce swelling and lowers your risk of blood clots.
3. Heel Slides
While lying on your back, bend your knee and slide your heel slowly toward your body. This gentle stretch can improve knee flexibility and reduce stiffness.
4. Standing Marches
With support from a chair or countertop, slowly lift one knee at a time in a marching motion. This encourages balance and strengthens the hip flexors and thighs.
5. Stationary Cycling
Once approved by your surgeon or physical therapist, using a stationary bike is a great way to reintroduce fluid movement without placing stress on the joint. Start with short sessions and low resistance.
6. Walking
Walking is one of the most effective long-term activities after knee replacement. Begin with short, slow walks and increase your distance and pace over time, based on comfort and physician guidance.
When to Start Exercising After Surgery
Movement typically begins the same day or the day after your knee replacement, but each patient’s recovery plan is personalized. It's important to work with your medical team to determine the right pace and to avoid doing too much too soon. Progress may feel slow, but small, consistent efforts make a big impact over time.
Listen to Your Body
Discomfort is normal during recovery, but sharp pain, swelling, or warmth around the joint may signal overuse or other complications. Always check with your orthopedic provider if something doesn’t feel right.
