Taking care of yourself and being patient will help you heal after knee replacement surgery.  The surgery will help with pain and movement, but the real success of the procedure depends on how well you stick to your recovery plan, especially the exercises you do after knee replacement.

Our orthopedic specialists at Zynova Shalby Hospital always stress that physiotherapy and simple daily exercises are just as important as the surgery itself.  These movements will help your knee get stronger, become more flexible, and make it easier for you to get back to your normal life.

Why Are Exercises Important After Knee Replacement?

A lot of people think that just resting after surgery is enough, but that’s not true.  If you don’t do your exercises, your knee can get stiff and weak, which will make it take longer and hurt more to heal.

Regular rehabilitation exercises after knee replacement are crucial because they:

• Make blood flow better and stop clots from forming.
• Make the joint less swollen and stiff.
• Strengthen the muscles around the knee to give it more support.
• Get back your balance and ability to walk.
• Make sure your new knee joint lasts a long time.

When Can You Start Exercises After Knee Replacement?

Most patients can start moving around gently within 24 hours of surgery with the help of a physiotherapist.  As you get better, the routine gets better:

• Weeks 1–3: Exercises to improve flexibility and range of motion.
• Weeks 4–6: Practice walking and getting stronger.
• After six weeks: Activities that don’t put too much stress on your body to build endurance.
• Before starting or changing your exercise plan, always listen to what your doctor says.

Best Exercises After Knee Replacement

Here are some safe and effective exercises that our experts at Zynova Shalby Hospital often recommend:

1. Pumps for the Ankles :

• Put your back flat on the ground.
• Move your ankle up and down slowly, like you’re pressing and releasing a pedal.
• Do it again 10–15 times.

Helps with swelling and better blood flow.

2. Sets for the quadriceps :

• Sit with your leg straight on the bed.
• Tighten your thigh muscles and push the back of your knee downwards.
• Hold for 5–10 seconds, then relax.

Builds thigh strength and improves knee stability.

3. Heel Slides : 

• Lie on your back with legs stretched.
• Slowly slide your heel toward your hip, bending the knee.
• Hold for a few seconds, then straighten the leg.

Improves flexibility and bending ability.

4. Straight Leg Raises

• Lie down with the operated leg straight and the other bent.
• Lift the operated leg about 6–12 inches from the bed.
• Hold for 3–5 seconds, then lower slowly.

5. Knee Bends (Seated or Standing)

• Sit on a chair or stand with support.

Safety Tips While Doing Exercises

While these exercises are safe, precautions are always important:

• If you experience severe pain, stop (some discomfort is normal).
• Steer clear of high-impact exercises like jumping and running.
• Exercise on a level, secure surface at all times.
• Utilize assistance as soon as possible.
• Never miss a follow-up appointment with your physiotherapist.

Long-Term Exercises for Knee Health

Once your recovery is complete, you can adopt low-impact exercises to keep your knee strong and flexible:

• Swimming – Gentle and effective without putting weight on the knee.
• Cycling – Builds strength and range of motion.
• Yoga and stretching – Enhances flexibility and balance.
• Light strength training – Keeps muscles strong for joint support.

Conclusion

Recovery from knee replacement surgery is a process that requires patience, and exercising is the most important step in the process. Exercising after knee replacement makes a person feel better, more comfortable, and confident to perform daily activities again.

At Zynova Shalby Hospital in Ghatkopar, Mumbai, we feel that surgery is just half the process of recovery; complete rehabilitation is equally essential. Our experienced orthopedic surgeons and physiotherapy staff work closely with every patient to develop exercise programs that are both secure and efficient, promoting faster recovery and better long-term results.
