Joint replacement is increasingly done in people in their fifties and sixties, and women make up the majority of patients. Several things specific to this life stage affect the decision, the operation and the recovery — and most of them are not raised in a standard pre-operative appointment.

Where we stand: Menova is an independent publication. We sell no services, we are not your doctor, and this is general education, not medical advice. Decisions about surgery and medication belong with your surgical team.

Before deciding on surgery

Exercise therapy first is not a delaying tactic. For knee and hip osteoarthritis, structured exercise and strengthening are recommended before surgery in essentially every guideline, and a proportion of people improve enough not to need an operation.

If you are told to lose weight and do physiotherapy first, that is standard practice rather than a fob-off — though the standard also includes actually being referred to physiotherapy, which does not always happen. Ask for the referral. See knee pain in midlife and strength training in menopause.

Build strength before the operation. "Prehabilitation" — strengthening in the weeks before surgery — is associated with better recovery. Going in stronger comes out better, and this is the most useful thing you can do while waiting.

Check it is the joint. Hip osteoarthritis is groin pain and stiffness. Pain over the outer hip, worse lying on that side at night, is usually gluteal tendinopathy — a different problem that does not need a hip replacement and is frequently confused with one; see pain on the outside of your hip.

Hormone therapy around the operation

The question that comes up and is answered inconsistently.

The concern is clot risk. Joint replacement is major surgery with a period of reduced mobility, and that raises venous thromboembolism risk substantially.

The route matters:

  • Oral estrogen raises clot risk and may be reconsidered
  • Transdermal estrogen — patch, gel, spray — is not associated with the same increase, and is often continued

Ask specifically: "Is this advice because my estrogen is oral? Would switching to transdermal change it?" That question resolves a surprising number of blanket instructions to stop.

Vaginal estrogen is a different medicine with minimal systemic absorption and generally continues — but it must be on your medication list, which is where it is most often lost; see going into hospital while you are on HRT.

If you are told to stop, get the restart date written down. See HRT and surgery.

Clot prevention, which matters more here than usual

You will be offered thromboprophylaxis — stockings, calf pumps, early mobilisation, and usually blood-thinning medication for a period after discharge. Use all of it.

Know the warning signs, during admission and for weeks afterwards: pain, swelling, warmth or redness in one calf; sudden breathlessness; chest pain worse on breathing in; coughing blood. Seek emergency care for these.

If you end up on an anticoagulant and are still having periods, heavy bleeding is a common consequence with real solutions — see heavy periods while taking a blood thinner.

Bone, which affects the surgery itself

Worth raising explicitly, because it is not routinely assessed before joint replacement.

Bone quality affects implant fixation and the risk of periprosthetic fracture — a fracture around the implant, which is a serious complication and more likely in poor bone.

If you have risk factors — early menopause, previous fragility fracture, long-term steroids, low body weight, a parent who fractured a hip, or you are on an aromatase inhibitor — ask whether a bone density assessment is warranted before surgery.

Treating osteoporosis before or around a joint replacement is a reasonable question and is frequently not asked. See bone health in menopause and what to do about a DEXA result.

Recovery, and the midlife-specific parts

Muscle is lost fast during immobility and regained slowly, and that is worse in midlife than at 30. Getting moving as early as permitted is not enthusiasm — it is protecting the muscle you will need to rehabilitate.

Alongside that:

  • Protein. Requirements rise around surgery, and intake typically falls. This is one of the more consequential and least mentioned parts of recovery — see how much protein you need and muscle loss in midlife
  • Iron. Joint replacement involves blood loss, and many midlife women start already iron-deficient from heavy periods. Ask for ferritin before surgery, since correcting it improves recovery — see how to actually take iron
  • Constipation from opioid painkillers is near-universal, and straining is bad for the pelvic floor. Ask for laxatives from day one — see fibre in midlife and haemorrhoids and bowel changes
  • Urinary infection risk rises with catheters and reduced mobility, and thin postmenopausal tissue adds to it — another reason vaginal estrogen belongs on the chart; see recurrent UTIs after menopause
  • Sleep. A hospital ward plus night sweats plus post-operative pain is a poor combination, and poor sleep raises pain perception. Ask for a fan and lighter bedding
  • Hot flashes get investigated as infection on a ward. Say what your normal flashes look like so a genuine fever is not lost in the noise

Pain relief and the hot flash question

Worth knowing: several medications used around surgery affect thermoregulation, and some antidepressants used for pain can worsen sweating.

Conversely, some non-hormonal treatments for hot flashes interact with other medications. Bring your full list — see keep your own health record.

Realistic expectations

  • Hip replacement generally produces faster, more predictable relief than knee replacement
  • Knee replacement takes longer to recover from, and a proportion of people have residual discomfort or stiffness. This is worth knowing beforehand rather than discovering afterwards
  • Rehabilitation is the determinant. The operation creates the opportunity; the physiotherapy produces the outcome
  • Implants last a long time, though revision is a consideration when replacing a joint at 55 rather than 75 — worth discussing

Questions to ask

  • "Have I had a proper trial of exercise therapy?"
  • "Should I have prehabilitation before the operation?"
  • "Given my history, should my bone density be assessed first?"
  • "Do I need to stop my HRT — and would transdermal change that?"
  • "Can I have ferritin checked and corrected before surgery?"
  • "What does realistic recovery look like at my age?"
