Facing knee replacement surgery? It’s a big step toward a pain-free, more active life. Whether you’re struggling with osteoarthritis or a lingering injury, this procedure can restore your mobility and quality of life. However, strengthening the muscles around your knee before surgery helps improve stability, reduces discomfort, and speeds up rehabilitation—setting you up for the best possible outcome. 

To help you prepare, here are ten highly recommended exercises to strengthen your knees before knee replacement surgery: 

1. Quadriceps Sets 

Why It Matters: Your quadriceps—the powerhouse muscles at the front of your thigh—play a vital role in knee movement and stability. Before knee replacement surgery, keeping these muscles strong can support better mobility and balance, making everyday activities easier. 

How to do it 

• Sit on the floor with your legs extended.  

• Tighten your thigh muscles and press the back of your knee down toward the floor.  

• Keep the muscles contracted for 5 to 10 seconds. After that, release.  

• Repeat 10-15 times per leg. 

2. Straight Leg Raises 

Why It Matters: Building strength in your quadriceps is vital before knee replacement surgery, as strong muscles help support the joint and aid in post-surgery recovery. Straight leg raises target the quadriceps without bending the knee, making them an effective way to maintain muscle tone while keeping pressure off the joint. This exercise can improve mobility, enhance stability, and contribute to a smoother rehabilitation process. 

How to do it 

• While lying on your back, bend one knee and keep the other leg extended. 

• Slowly lift the straight leg to about 12 inches off the ground.  

• Hold the position for a few seconds, then slowly lower it back down.  

• Perform 10-15 repetitions per leg. 

3. Heel and Calf Raises 

Why It Matters Before Knee Replacement Surgery: Strong lower legs act as shock absorbers for your knees and help them handle movement with more stability. Heel and calf raises target key muscles in your calves and ankles. By strengthening your calves, you create a solid foundation that supports movement and reduces strain on your knees. This exercise also promotes better circulation, which can help with recovery post-surgery. 

How to do it 

• Stand upright, holding onto a chair or counter for balance. 

• Slowly lift your heels off the floor, rising onto your toes. 

• Hold the position for 2-3 seconds, then gently lower your heels back down. 

• Perform 10-15 repetitions. 

4. Hamstring Curls 

Why It Matters: Strong hamstrings play an important role in stabilizing the knee joint. Therefore, strengthening these muscles before knee replacement surgery can make movement easier, enhance joint support, and contribute to a smoother recovery process. A well-prepared knee can also help maintain better posture and balance, making post-surgery mobility more manageable. 

How to do it 

• Stand behind a chair for support. 

• Slowly bend one knee, bringing your heel toward your buttocks. 

• Hold the position for a second, then lower your foot back to the floor. 

• Repeat 10-15 times on each leg. 

5. Seated Knee Extensions 

Seated knee extensions target the quadriceps. Therefore, strengthening these muscles before knee replacement surgery can help improve mobility and reduce strain on the joint. 

How to do it 

• Sit in a sturdy chair with both feet flat on the floor. 

• Slowly extend one leg until it is fully straight. 

• Hold the position for 3-5 seconds, engaging your thigh muscles. 

• Gently lower your leg back to the starting position. 

• Repeat 10-15 times for each leg. 

6. Step-Ups 

Why It Matters Before Knee Replacement Surgery: Step-ups help build strength in your legs, making daily movements like walking and climbing stairs feel more natural after surgery. They also boost balance, reducing the risk of falls before and after the procedure. Therefore, strengthening your lower body in advance can make recovery smoother and help you stay mobile with greater ease. 

How to do it 

• Use a low step or a sturdy platform. 

• Step up with one foot, then bring the other foot up to meet it. 

• Step back down one foot at a time. 

• Repeat 10-15 times per leg. 

Final Thoughts 

Strengthening your knees before knee replacement surgery can significantly improve your recovery time and post-surgical mobility. These exercises help condition the surrounding muscles, making daily movements easier and reducing discomfort. By committing to a structured prehabilitation routine, you’ll be setting yourself up for a more successful surgery and a quicker return to pain-free movement.
