Safe, effective exercises for knee osteoarthritis you can do at home. A practical step-by-step routine to build strength, reduce pain, and protect your knees.
Why exercise matters in knee OA
Many patients believe rest is best. The opposite is closer to the truth: strong muscles around the knee are your single most reliable, drug-free pain reducer. Done correctly, exercise reduces pain, improves function, and slows progression.
Always combine exercise with the rest of your plan — see osteoarthritis knee treatment and non-surgical knee pain treatment.
Three rules before you start
- Pain, not rest, decides the dose. A little discomfort is fine; sharp or worsening pain isn't.
- Consistency beats intensity. 3 short sessions a week for 12 weeks beats 1 hard session.
- Form first, weight later. Especially on stairs, squats, and lunges.
A simple home routine
Aim for 3 sessions per week. Each session takes about 20 minutes. Always warm up with 5 minutes of gentle walking or marching in place.
1. Quadriceps activation (sitting)
Sit on a firm chair, both feet flat. Slowly straighten one knee, hold for 3 seconds at the top, lower. 2 sets of 10 each leg.
2. Straight leg raise (lying)
Lie on your back, one knee bent, the other straight. Slowly lift the straight leg to the height of the bent knee, hold 2 seconds, lower. 2 sets of 10 each leg.
3. Wall sit (modified)
Stand with your back against a wall. Slide down only as far as comfortable — typically a small bend. Hold for 10–20 seconds. Build up over weeks. 3 holds total.
4. Heel raises
Stand near a counter for balance. Rise up onto the balls of your feet, lower slowly. 2 sets of 10–15.
5. Glute bridge
Lie on your back, knees bent, feet flat. Lift your hips up so the body forms a straight line from shoulder to knee. Hold 3 seconds, lower. 2 sets of 10.
6. Side-lying hip lift (clamshell)
Lie on your side, knees bent and stacked. Open the top knee while keeping feet together. 2 sets of 10–15 each side.
7. Mini step-ups
Use a low step or thick book. Step up with one foot, bring the other up, step down. 2 sets of 10 each leg. Use a railing for balance.
8. Hamstring stretch
Sit on the floor, one leg straight, the other bent. Reach gently toward your toes — only as far as comfortable. Hold 20–30 seconds. Repeat each side.
9. Calf stretch
Stand at a wall, one leg back with heel down. Lean forward gently. Hold 20–30 seconds each side.
10. Closing walk
5 minutes of relaxed walking to finish.
If you have post-injection day, recent surgery, or severe pain, modify or skip — and always follow your physiotherapist's specific advice.
Activities that usually help
- Stationary cycling (light resistance)
- Swimming and aqua walking
- Brisk walking on flat ground
- Pilates and yoga (guided, OA-aware)
- Light gym strength work with good form
Activities that may need modification
- Deep squats
- High-impact running on hard surfaces
- Long stair-climbing sessions during flares
- Plyometrics (jumping)
- Sudden direction changes (basketball, badminton during flares)
How to handle a flare
- Reduce activity — don't stop entirely.
- Apply ice for 15 minutes 2–3 times a day.
- Stick to low-impact movement (stationary bike, gentle walking).
- Keep up your seated strengthening exercises.
- Reach out to your doctor if a flare lasts more than a week.
When to escalate care
- Pain isn't improving after 4–6 weeks of consistent exercise
- Swelling lingers
- New instability or catching
- Sleep is being disrupted
A clinical assessment may add HA injections, GFC, or other targeted care to your plan.
