How Long Does It Take to Recover From a Knee Replacement?

The recovery time depends on the patient’s age, fitness level, health status, surgery type, and rehabilitation progress. It takes just one or two days to stand and walk on your own with support after knee replacement surgery. However, in most cases, it takes months for the knee joint to completely heal and regain full mobility.

According to the American Academy of Orthopaedic Surgeons (AAOS), patients return to most of their daily activities after 3-6 weeks and fully recover 1 year after the surgery:

• Walking with support – 1–2 days after knee replacement,
• Improved mobility – between 4 and 6 weeks after surgery,
• Returning to most activities – between 6 and 12 weeks after knee replacement,
• Additional recovery for full joint mobility – for up to 12 months after the surgery.
