Total knee replacement (TKA)
Replace damaged surfaces when the time is right.
Who might it suit?
For: Symptoms and joint damage that justify replacement after other care has failed.
Not for: An X-ray alone, without symptoms, examination, and a shared decision.
Limits and important cautions
Recovery takes work and improvement is not guaranteed. Infection, clots, stiffness, persistent pain, and revision belong in the surgical discussion.
What happens, how long, and what could it cost?
- What happens
- Specialist evaluation, imaging review, shared decision-making, and preparation for an operation.
- When might I notice a change?
- Recovery and rehabilitation take time; discuss milestones rather than a guaranteed recovery date.
- How long might benefit last?
- Long-term outcome and the chance of further surgery depend on the operation, implant, and patient.
- Repeat treatment
- Ask about routine follow-up and circumstances that could require revision or another operation.
- Activity and recovery
- Obtain individualized instructions for walking aids, wound care, work, driving, and rehabilitation.
- Ask for a complete estimate
- Surgeon, implant, hospital or facility, anesthesia, rehabilitation, and follow-up.
Use this as a consultation guide. A timeline is not a guarantee; the evidence and FDA sections below remain part of the decision.
THE EVIDENCE IN CONTEXT
Established treatment when symptoms justify surgery
Read the 2 selected references
- Skou et al.: knee replacement versus nonsurgical care ↗
Replacement plus rehabilitation improved symptoms more at one year, with more serious adverse events. Participants were already eligible for replacement.
- ACR/AAHKS: timing of hip and knee replacement ↗
Applies to patients already indicated for replacement after unsuccessful nonsurgical care. It does not determine candidacy from an X-ray alone.

AAHKS: When moderate-to-severe symptoms remain after non-operative care and you have chosen an indicated replacement, ACR/AAHKS conditionally recommend proceeding without a required trial of more PT, anti-inflammatories, or injections. Medical optimization still matters.
