Knee Osteoarthritis: exercise plan
Exercise is the main treatment for knee osteoarthritis, not a consolation prize. Your knee isn’t wearing out from use; it gets stronger with it.
- Pain rules: up to about 3–4/10 during exercise is fine (some sources say 5/10), as long as it settles within 24 hours. Flared up? Do fewer reps, not none.
- How often: 2–3 times a week for strength, plus walking most days.
- How long: most people notice less pain and better function after 6–8 weeks; keep it up for life.
- Progress when: you can do all sets with good control and pain stays under 4/10. Add reps, a band, a step or a backpack with weight.
Your exercises
- Sit to standStand up from a chair without using your hands, then sit back down slowly. Start with a higher chair or use your hands lightly; progress to a lower chair, holding a weight, or one leg doing more of the work.3 sets of 10, 2–3 times a week
- Step-upsStep up onto a low step leading with the sore leg, keeping your knee over your second toe (not dropping inwards). Start with a 10 cm step and hold a rail; progress to a higher step or a backpack.3 sets of 10 each leg, 2–3 times a week
- Mini squat with controlFeet hip-width apart, bend your knees as if sitting back, keeping them in line with your toes. Use a mirror to check knee alignment. Progress by going deeper, slower, or with a band above the knees.3 sets of 10, 2–3 times a week
- Knee straightening (seated)Sit tall and straighten one knee fully, hold 3 seconds, lower slowly. Start with no weight; add an ankle weight or band as it gets easy.3 sets of 10 each leg, 2–3 times a week
- Side-step with bandBand around your ankles or knees, step sideways keeping hips level. Start without a band; progress to a stronger band or more steps.3 sets of 10 steps each way, 2–3 times a week
- Single-leg balanceStand on one leg near a bench for support. Start with fingertip support; progress to eyes closed, a cushion, or a slight knee bend.3 holds of 30 seconds each leg, most days
Also: walk most days, aiming to build to 30 minutes. Cycling, swimming and tai chi count too. If you’re carrying extra weight, losing even 5–10% helps knee pain.
Stop and see your GP or physio if
- Your knee is hot, red and swollen, especially with fever (same day)
- Your knee locks, gives way often or you can’t take weight
- Pain at night or at rest that keeps getting worse
- No improvement after 3 months of regular exercise
Want a supervised program?
GLA:D is a supervised 6–8 week education and exercise program for hip and knee osteoarthritis, run by trained physios across Australia (search ‘GLA:D Australia’ to find a clinic). A physio or exercise physiologist can also build a program around you. If you have a chronic condition, ask your GP about a GP Chronic Condition Management Plan (GPCCMP): it gives a Medicare rebate for up to 5 allied health visits a year (physio, exercise physiologist or podiatrist).
