Exercises For Strengthening Your Knees Post-Surgery

Recovering from knee surgery can be a challenging but rewarding process. Whether you’ve undergone a knee replacement, ligament repair, or meniscus surgery, strengthening the knee is a crucial step in regaining mobility and reducing the risk of further injury. At Lokmanya Hospital, we are committed to providing comprehensive care for knee surgery patients.

The Importance Of Post-Surgery Knee Strengthening

After knee surgery, the muscles around the joint, particularly the quadriceps, hamstrings, and calf muscles, may weaken due to immobility, pain, or disuse. Weak muscles around the knee joint can lead to instability, reduced range of motion, and difficulty with daily activities like walking, standing, or climbing stairs. By engaging in a consistent and progressive exercise routine, you can rebuild muscle strength, improve joint stability, and promote faster healing.

When To Start Exercises After Knee Surgery

It’s crucial to start knee rehabilitation exercises only once your doctor or physical therapist has given you the go-ahead. The timeline for beginning exercises can vary depending on the type of surgery you had and your individual recovery progress.

In most cases, rehabilitation will begin with gentle, non-weight-bearing exercises and progress as your strength and mobility improve. Always consult with your healthcare provider to ensure you’re performing exercises appropriate for your specific situation and recovery stage.

Types Of Exercises For Strengthening Knees Post-Surgery

Always start slowly, listen to your body, and avoid any exercises that cause pain or discomfort.

1. Quadriceps Sets

The quadriceps are the muscles at the front of your thigh that play a significant role in stabilizing the knee joint.

How to perform:

• Sit or lie down with your leg straight out in front of you.
• Tighten the muscles on the top of your thigh (quadriceps) by pressing the back of your knee down toward the floor.
• Hold for 5 seconds, then relax.
• Perform 10–15 repetitions, 2–3 times per day.

This exercise helps to activate the quadriceps and restore normal muscle function around the knee.

2. Straight Leg Raises

Straight leg raises are an excellent way to strengthen the quadriceps and hip flexors without putting pressure on the knee.

How to perform:

• Lie flat on your back with one leg bent and the other straight.
• Tighten the muscles on the top of your thigh of the straight leg and lift it slowly to about the height of the opposite knee.
• Hold for a few seconds, then lower the leg back down.
• Perform 10–15 repetitions on each leg, 2–3 times per day.

Straight leg raises target the quadriceps and can help restore knee stability without straining the joint.

3. Hamstring Curls

The hamstrings are the muscles located at the back of your thigh and play a key role in knee stability.

How to perform:

• Stand holding onto a stable surface like a chair or countertop for support.
• Slowly bend your knee, bringing your foot toward your buttocks.
• Hold for a few seconds, then slowly lower the leg back down.
• Perform 10–15 repetitions on each leg, 2–3 times per day.

This exercise strengthens the hamstrings, which is essential for maintaining knee strength and stability.

4. Calf Raises

Calf raises are an effective exercise for strengthening the muscles in your calves and improving the range of motion of the knee joint.

How to perform:

• Stand with your feet hip-width apart and hold onto a chair or wall for support.
• Slowly raise your heels off the ground as high as possible, balancing on the balls of your feet.
• Hold for a few seconds, then lower your heels back to the ground.
• Perform 10–15 repetitions, 2–3 times per day.

Calf raises not only help improve knee function but also work the calf muscles, improving overall lower limb strength.

5. Step-Ups

Step-ups are a functional exercise that mimics real-world movements, like climbing stairs, and helps improve knee strength, balance, and coordination.

How to perform:

• Stand in front of a low step or platform.
• Step up with one leg, bringing the other leg up to meet it.
• Slowly step back down with one leg, followed by the other leg.
• Perform 10–15 repetitions on each leg, 2–3 times per day.

Step-ups are excellent for building strength in the quadriceps and hamstrings while improving your ability to perform daily activities.

6. Wall Sits

Wall sits are a great exercise to strengthen your quadriceps and lower body while also improving endurance.

How to perform:

• Stand with your back against a wall, feet shoulder-width apart.
• Slowly slide down the wall until your knees are at a 90-degree angle.
• Hold the position for 10–30 seconds, then slowly slide back up.
• Perform 5–10 repetitions, 2–3 times per day.

7. Lunges

Lunges are a great way to strengthen the entire lower body and improve knee function.

How to perform:

• Stand with your feet shoulder-width apart.
• Step forward with one leg, lowering your hips to create a 90-degree angle at both knees.
• Push back up to the starting position, then repeat on the other leg.
• Perform 8–12 repetitions on each leg, 2–3 times per day.

Lunges target the quadriceps, hamstrings, and glutes, helping to improve balance, coordination, and strength around the knee.

Tips for Successful Knee Rehabilitation

• Start Slowly: Gradually increase the intensity and duration of exercises as your knee gets stronger. Avoid rushing the process to prevent overloading the joint.
• Listen to Your Body: Mild discomfort is normal during rehab, but stop any exercise that causes sharp or intense pain. Consult your doctor or physical therapist if you have concerns.
• Stay Consistent: Consistency is key to rebuilding strength and range of motion. Stick to your rehabilitation schedule, and make exercise a daily habit.
• Use Ice and Elevation: After completing your exercises, apply ice to the knee for 15-20 minutes to reduce swelling and inflammation. Elevating the leg also helps to minimize swelling.
• Wear Proper Support: Depending on your recovery, your doctor might recommend wearing a knee brace or compression sleeve to support the joint during exercises.
