Knee Stiffness After Total Knee Replacement: Recovery Timeline

Stiffness after total knee replacement (TKR) is normal and gradually improves with rehabilitation.

Typical Timeline

  • 1–2 weeks: Significant stiffness and swelling; walker/crutches needed.
  • 2–6 weeks: Physical therapy improves range of motion; gradual improvement; may walk with slight limp.
  • 6–12 weeks: Continued PT; significantly less stiffness; more comfortable walking.
  • 3–6+ months: Most regain near-full motion; minimal residual stiffness; ongoing low-impact exercise maintains mobility.

Keys to Recovery

  • Follow prescribed rehab plan diligently.
  • Regular exercise and movement are crucial.
  • Consult surgeon/PT if concerned about progress.
