Joint Replacement: The Questions People Actually Ask

Surgical replacement of a damaged hip or knee joint with an artificial one.

Key takeaways

  • Most common: hip and knee replacement
  • Prehabilitation: exercise before surgery improves recovery
  • Most useful single change: Do prescribed exercises before surgery, not only after.
  • Commonest mistake: Delaying so long that muscle loss makes recovery harder.
  • See a doctor if any of the signs under "When to speak to a doctor" below apply to you.

Surgical replacement of a damaged hip or knee joint with an artificial one.

Why does it matter?

Outcomes are strongly influenced by preparation and rehabilitation, which are the parts patients can actually affect.

Hip and knee replacement.

Typical hospital stay for Joint Replacement?

Often 1-3 days.

Implant longevity for Joint Replacement?

Most last many years; revision is possible.

When should I see a doctor?

Seek urgent help for increasing pain, redness, heat or discharge around the wound, fever, or a sudden inability to weight-bear — prosthetic joint infection needs immediate assessment. Call 999 for calf pain and swelling, chest pain or sudden breathlessness, which can indicate a clot.

How this page was put together

Every figure, recommendation and warning above is taken from the guidance named in Where this comes from. Nothing on this page is inferred, summarised or generalised beyond what those bodies publish: where they give a number, it is their number, and where they are silent, so are we. Pages are rebuilt whenever the underlying record changes. Sign-off by a named clinician, where it has happened, is shown at the top of the page along with the date.

Always speak to a GP, pharmacist or another qualified health professional before making changes that affect your treatment, and never delay seeking medical advice because of something you have read here.
