If you’re wearing a knee brace or sleeve, you’ve already taken the first step toward protecting your joint. But here is the secret of recovery: A brace is a stabilizer, but your muscles are the actual shock absorbers.
When your knee is swollen or weak, your quadriceps (thighs) and glutes (butt) often switch off to protect the joint. We want to wake them up without putting too much stress on the knee.
Here are five low-impact exercises you can do while wearing your knee support to build strength and flush out that lingering inflammation.
- The Quad Set
This is the safest exercise in the world for a bad knee. You aren’t even moving the joint; you’re just waking up the muscle.
- How to do it: Sit on the floor or a firm bed with your leg straight out in front of you.
- The Move: Tighten the muscle on the top of your thigh (the quad) by trying to push the back of your knee down into the floor.
- The Hold: Imagine you’re trying to squash a grape behind your knee. Hold for 5 seconds, then relax.
- Why it works: It builds muscle tension without any grinding or clicking in the joint.
2. Straight Leg Raises
Once your quads are awake, it’s time to lift. This strengthens the hip and thigh without bending the knee, which is usually where the pain happens.
- How to do it: Lie on your back. Keep the leg with the brace perfectly straight. Bend your other knee and then put that foot flat on the floor for support.
- The Move: Slowly lift your straight leg up until it’s about the same height as your bent knee.
- The Hold: Pause for a second at the top, then lower it back down in a slow manner.
- Why it works: It works the muscles that stabilize the knee from above.
3. Heel Slides
If your knee feels stiff, we need to gently regain that range of motion. The brace helps keep the kneecap (patella) tracking correctly while you move.
- How to do it: Sit on the floor with your legs out.
- The Move: Slowly slide your heel toward your butt, bending the knee as far as is comfortable.
- The Hold: Give it compression at the top, then slide it back out.
- Pro Tip: If you’re on carpet, wear a sock so your foot slides easily. If you’re on wood, put a small towel under your heel.
4. Clamshells
Most knee pain actually starts in the hips. If your hips are weak, your knee collapses inward. We want to prevent that.
- How to do it: Lie on your side with your knees bent and stacked on top of each other. (Your brace might feel a bit bulky here, and that’s okay).
- The Move: Keep your feet together and lift your top knee up like a clamshell opening.
- The Key: Don’t let your hips roll backward. Keep your belly button pointing forward.
- Why it works: It strengthens the gluteus medius, which is the anchor that keeps your knee aligned when you walk.
5. Standing Calf Raises
If you have swelling, your calves act like a second heart, pumping fluid back up your leg and out of the danger zone.
- How to do it: Stand behind a chair or at a kitchen counter for balance.
- The Move: Slowly rise up onto your tiptoes, hold for a beat, and lower back down.
- Why it works: Strong calves take the braking pressure off your knees when you walk downhill or down stairs.
- Terminal Knee Extensions (TKEs)
While the Quad Set wakes the muscle up, the TKE teaches it how to lock out and support your weight while standing. This is vital for walking without a giving way sensation.
- How to do it: Loop a resistance band around a sturdy table leg and place the other end behind your braced knee. Face the anchor point.
- The Move: Start with a slight bend in the knee. Slowly straighten your leg by pushing your knee back against the resistance of the band until your leg is straight.
- The Hold: Squeeze your quad hard for 2 seconds, then slowly let the band pull your knee back to a slight bend.
- Why it works: it builds end-range strength, which is exactly what you need to keep your knee stable when your foot hits the ground.
7. Glute Bridges
Your glutes are the strongest muscles in your lower body. If they aren’t firing, your knee has to work twice as hard to stabilize your gait.
- How to do it: Lie on your back with both knees bent and feet flat on the floor, hip-width apart.
- The Move: Squeeze your glutes and lift your hips toward the ceiling until your body forms a straight line from shoulders to knees.
- The Key: Keep your weight in your heels, not your toes. Ensure your braced knee stays aligned with your hip and doesn’t wobble inward.
- Why it works: It builds posterior chain strength without putting any shearing force on the knee joint.
8. Seated Leg Extensions (Iso-Hold)
This is a controlled way to build the teardrop muscle (vastus medialis) just above the kneecap, which is often the first muscle to shrink after an injury.
- How to do it: Sit in a sturdy chair with your back straight and feet flat on the floor.
- The Move: Slowly straighten your braced leg out in front of you until it’s parallel to the floor.
- The Hold: Point your toes toward your face as well as hold for 10 seconds. Focus on the muscle tension right above your brace.
- Why it works: It allows for high-intensity muscle contraction without the impact of carrying your full body weight.
A Quick Note on Pain: While some muscle burn is good, sharp or stabbing pain is your body’s way of saying not yet. If an exercise hurts, skip it and then stick to the ones that feel stable.
