Total Knee Replacement (TKR) replaces damaged knee joint surfaces — usually worn down by arthritis — with smooth metal and plastic implant components. Recovery is a gradual process, and while every patient heals at their own pace, most follow a broadly similar timeline.
Day 0–2: Hospital stay
Most patients are encouraged to stand and take a few assisted steps within a day of surgery. Pain is managed with medication, ice, and elevation. Physiotherapy typically starts almost immediately, focusing on gentle knee bending and straightening exercises.
Week 1–2: Early home recovery
Walking with a frame or crutches at home, wound checks, and daily exercises to regain knee bend (flexion) and straightening (extension) are the focus. Swelling and stiffness are common and expected during this stage — ice, elevation and prescribed exercises help manage both.
Week 3–6: Building strength
Many patients transition from crutches to a cane, and from a cane to walking unaided, during this window. Physiotherapy shifts toward strengthening the muscles around the knee and improving range of motion. Light daily activities and short outdoor walks are usually encouraged.
Week 6–12: Return to normal activity
By this stage, most patients can resume desk work, driving (once off strong pain medication and with adequate knee control), and most non-impact daily activities. Physiotherapy often continues to fine-tune strength, balance and gait.
3–6 months and beyond
Continued improvement in strength and stamina typically continues for up to a year. Most patients report significant pain relief and improved mobility well before this point, with swelling and residual stiffness resolving gradually over months.
Tips that help recovery go smoothly
- Stay consistent with prescribed physiotherapy exercises, even when it's uncomfortable — motion is medicine after TKR.
- Use ice and elevation regularly in the first few weeks to control swelling.
- Set up your home in advance: clear walkways, a stable chair with arms, and avoid low seating.
- Don't skip follow-up visits — they let your surgeon catch and address issues early.
When to contact your surgeon
Increasing redness, warmth or discharge at the wound site, fever, sudden increase in pain or swelling, or calf pain/swelling should prompt an urgent call to your surgical team rather than waiting for a scheduled follow-up.
