Runner’s Knee (Kneecap Pain)
An ache around or behind the kneecap that hates stairs, squats, running and long sits. Not damage, not arthritis: an irritated, overloaded joint. Stronger hips and thighs are the best-tested fix.
Typical signs: a dull ache at the front of the knee, worse going down stairs or hills, squatting, kneeling, running, jumping or after sitting with bent knees (the “movie-goer’s sign”). The knee may click or creak; that alone isn’t harmful.
Why it happens: more load on the kneecap joint than it’s used to: a jump in running or training, lots of stairs or squats, weaker hip and thigh muscles. Common in teenagers, runners and active women, but anyone can get it. Also called patellofemoral pain.
Diagnosis: from your story and a knee examination, including watching you squat or step down. X-rays and scans don’t help unless there was an injury, swelling or the knee locks or gives way.
The kneecap pain ladder
Exercise is the main treatment. Give it 6–12 weeks. Longer-standing pain takes longer, so start early.
- Step 1 · Self-careTweak the loadEase back on what flares it (hills, stairs, deep squats, long runs) without stopping activity. Keep pain mild and settling by the next day.
- Works
- No trials on its own, but part of every successful program
- Cost
- Free
- How long
- While it settles, then build back
- Watch for
- Total rest helps less than you’d hope and deconditions the muscles that protect the knee.
The knee is grumpy, not broken. Negotiate, don’t evacuate.
- Step 2 · Self-careHip and thigh strengtheningExercises like side-lying leg lifts, bridges, step-downs, wall sits and squats to a comfortable depth, 3 times a week.
- Works
- Pain during activity drops about 1.5 points out of 10 more than no exercise in the short term. Adding hip exercises to knee exercises lowered pain by about 2 more points
- Cost
- Free
- How long
- 6–12 weeks to judge; keep a few going after
- Watch for
- Mild pain during the exercises is OK if it settles soon and isn’t worse the next day.
Your hips have been freeloading. Time they paid rent.
- Step 3 · PharmacyOff-the-shelf insolesPrefabricated arch-support insoles, especially if they make stepping down feel easier straight away.
- Works
- Recommended by an international expert group for short-term pain relief; custom-made versions have no extra proven benefit
- Cost
- About $30–70
- How long
- Weeks to a few months
- Watch for
- If they don’t help within a few weeks, they probably won’t.
Try before you buy custom. Most people never need to.
- Step 4 · Allied healthPhysio-guided programExercise plus extras like taping or hands-on treatment to help you get moving, with a plan back to running or sport.
- Works
- Exercise combined with insoles, taping or hands-on care is recommended for short- and medium-term pain relief
- Cost
- About $90–130 a session; Medicare rebates with a GP care plan
- How long
- Usually 6–12 weeks
- Watch for
- Hands-on treatment or taping on their own, without exercise: not recommended.
Tape is the support act. Squats are the headliner.
- Step 5 · SpecialistSports physician or orthopaedic reviewFor pain lasting many months despite a good program, or if something else is suspected.
- Works
- Surgery has no proven role for typical kneecap pain
- Cost
- Specialist fees vary; Medicare rebates with a GP referral
- How long
- Depends on findings
- Watch for
- Be wary of offers of arthroscopy (“clean-out”) for this problem.
A scope won’t strengthen your glutes.
Save your money
Popular, heavily marketed or often asked about, but the evidence is weak or says no.
- Knee braces and patellar taping on their ownExperts rate the evidence as uncertain. Fine if they make exercise easier, but they’re not a treatment by themselves.
- Ultrasound, laser, TENS and other machinesNot recommended by the international expert consensus. Warm, buzzy and unhelpful.
- Custom orthoticsNo proven advantage over off-the-shelf insoles, at several times the price.
- Scans for typical kneecap painThey don’t change treatment and often show harmless “findings” that cause worry.
- Glucosamine and joint supplementsThis isn’t arthritis, and there’s no evidence they help kneecap pain.
What you can do
- Follow our kneecap pain exercise handout: hip and thigh exercises with reps and pain rules.
- Start early. Pain that has lasted more than 2 months tends to take longer to settle.
- Return to running gradually: shorter, flatter, softer surfaces first, and add a little each week.
- Avoid long sits with knees bent: stretch your legs out or stand up every 30–45 minutes.
- Cycling and swimming usually keep you fit without a flare.
- If you’re above a healthy weight, losing some eases load on the kneecap.
See your GP if
- Pain isn’t improving after 6–12 weeks of exercise
- The knee swells, locks, or gives way
- Pain started after a twist, fall or blow to the knee
- A child or teenager has knee pain with a limp, or pain at night
See a doctor the same day for a hot, red, swollen knee, especially with fever; a knee you can’t straighten or put weight on after an injury; or a child with knee pain and a limp (hip problems can show up as knee pain).
Common questions
Is runner’s knee damaging my knee?
No. It’s an irritated, overloaded joint rather than damage, and it doesn’t mean you’ll get arthritis. Clicking or creaking without pain or swelling is common and harmless.
How long does runner’s knee last?
Many people improve over 6 to 12 weeks of exercise, but it can linger: in one study about 4 in 10 weren’t recovered by 12 months. Starting exercises early helps.
Should I stop running?
Usually not completely. Cut back to a level that keeps pain mild and settled by the next day, add strengthening, then build back up gradually.
Should I use a knee brace?
Only if it makes moving easier. The evidence is uncertain, and it doesn’t replace exercise.
