Knees that ache on stairs, stiffen after sitting, or complain the day after a long walk. Knee pain becomes markedly more common in women around midlife, and the two things most people do about it — rest, and avoiding loading the joint — are usually the opposite of what helps.

Where we stand: Menova is an independent publication. We sell no treatments, we are not your doctor, and this is general education, not a diagnosis.

The common causes at this age

Patellofemoral pain — pain around or behind the kneecap, worse on stairs (especially down), after prolonged sitting, and when squatting. Usually a loading and muscle-control problem rather than joint damage. Very common and very responsive to strengthening.

Osteoarthritis — pain with use and better with rest, morning stiffness under about 30 minutes, sometimes swelling, grinding or a sense of giving way. Women's rates rise notably around and after menopause.

Menopausal arthralgia — aching and stiffness that migrates between joints, fluctuates, and eases within 20 to 30 minutes of moving; see menopause joint pain.

Tendinopathy — pain localised to a tendon, often after an increase in activity, part of the wider midlife pattern; see why you keep getting injured in midlife.

Meniscal degeneration. Worth knowing: degenerative meniscal tears are common findings on scans in this age group, they are frequently present in people with no pain at all, and arthroscopic surgery for degenerative tears without locking has repeatedly failed to outperform exercise therapy in trials. If surgery is suggested for a degenerative tear, exercise therapy first is a reasonable and evidence-based request.

Inflammatory arthritis — morning stiffness over an hour, visible swelling, both sides, feeling generally unwell. Needs prompt assessment; see autoimmune conditions and menopause.

Why midlife

  • Estrogen has receptors throughout the musculoskeletal system, including cartilage, and its decline is associated with changes in joint tissue
  • Muscle loss means less support around the joint, and the quadriceps are what protect the knee
  • Weight change matters mechanically — each kilogram is multiplied several times through the knee when walking, and more on stairs
  • Tendons and ligaments become less tolerant of sudden load increases
  • Sleep loss lowers pain thresholds — see perimenopause sleep problems

What actually helps

Strength training, especially quadriceps. This is first-line for both patellofemoral pain and knee osteoarthritis in essentially every guideline, and it is more effective than most people expect. Loading a painful knee under control is not damaging it; weak muscles around a joint are what leave it exposed.

Start where you can: sit-to-stand from a chair, wall sits, step-ups, leg press. Build progressively. See strength training in menopause and starting from zero.

Keep moving. Rest stiffens things and weakens the muscles you need. Reduce load rather than stopping.

Physiotherapy for a specific diagnosis and a progression that fits you. Self-referral is available in many places.

Weight management where relevant — the mechanical effect is large, and it compounds with strengthening.

Low-impact options while you build — cycling, swimming, cross-trainer. These keep you fit without the impact, and you return to walking and stairs stronger.

Topical NSAIDs, which work well for a superficial joint like the knee and carry fewer systemic effects than tablets.

Sleep, which changes pain perception directly.

What has weak evidence: glucosamine and chondroitin, where trial results have been largely disappointing, and most braces and taping used alone — see what the supplement research says.

The bone question

A knee point that is really a whole-body point.

If your knee pain is stopping you doing weight-bearing exercise, that has consequences beyond the knee: bone density falls fastest in the years around menopause, and loading is the only thing that builds bone rather than slowing its loss.

So the goal is not to protect the knee by doing less. It is to find loading the knee tolerates — which is what a physiotherapist is for. See bone health in menopause.

Get it assessed if

  • The knee locks, or gives way repeatedly
  • It is hot, red and swollen — particularly with fever, which needs urgent assessment
  • Sudden swelling after an injury
  • Morning stiffness over an hour, or several joints involved
  • You cannot weight-bear
  • Pain at rest or at night that is not related to position
  • Calf swelling or pain alongside it — see aching legs and varicose veins
  • No improvement after three months of consistent strengthening

Basic tests that sort out most of the alternatives: inflammatory markers, thyroid, vitamin D, and sometimes autoimmune serology. See vitamin D and calcium.

Does HRT help?

Nuanced, and worth stating carefully.

Data from the Women's Health Initiative and later analyses suggest hormone therapy can reduce joint pain for some women, and that pain may return after stopping. Research on hormone therapy and osteoarthritis specifically is mixed rather than conclusive.

Hormone therapy is not prescribed for joint pain. If you are already weighing it for other symptoms, joint pain is a reasonable thing to add to the discussion — not a reason to start. Be wary of anyone promising a guaranteed fix; see HRT risks and benefits.

Practical points

  • Going down stairs hurts more than going up — that is normal for patellofemoral pain, not a sign of damage
  • Stand up periodically if you sit for long stretches; "cinema sign" — stiffness after sitting — is characteristic
  • Do not stretch into sharp pain
  • Shoes matter more than knee braces for most people
  • Build up gradually. Most midlife knee pain follows a sudden increase in activity, not a lack of it

How to raise it

"I've had pain around my kneecap for three months, worst going down stairs and after sitting. No locking, no swelling, no injury. I'd like a physiotherapy referral for a strengthening programme, and I'd like inflammatory markers and vitamin D checked to be sure it isn't something else."

That describes the pattern, rules out the concerning features, and asks for the treatment with the best evidence.
