Total Knee Replacement

🦡 What Is a Total Knee Replacement?

A Total Knee Replacement (TKR) is a surgical procedure where the entire knee joint surface is replaced with artificial components made of metal and plastic. It's done to relieve severe pain and stiffness, usually caused by arthritis, injury, or other joint problems that haven’t responded to other treatments.

The goal is to restore mobility, reduce pain, and improve quality of life.

πŸ§‘β€βš•οΈ Who Needs a Total Knee Replacement?

You may be a candidate if you have:

  • Severe arthritis (osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis)

  • Persistent knee pain and stiffness

  • Difficulty walking, climbing stairs, or performing daily activities

  • Tried other treatments (medications, injections, physiotherapy) without success

πŸ› οΈ How Is It Done?

  • The worn-out cartilage and a small amount of underlying bone are removed from the thighbone (femur), shinbone (tibia), and sometimes kneecap (patella).

  • These surfaces are then replaced with metal implants, and a smooth plastic spacer is inserted between them to allow smooth movement.

  • The kneecap may also be resurfaced with a plastic button depending on the case.

    It can be done using traditional or robotic-assisted techniques for greater precision.

πŸ•’ Recovery Timeline

  • Hospital stay: 1–3 days

  • Walking with support: Often the same day or the day after surgery

  • Physiotherapy: Starts immediately and continues for several weeks to regain strength and motion

  • Return to normal daily activities: 4–6 weeks

  • Full recovery and return to more demanding activities: 3–6 months

🎯 Benefits of Total Knee Replacement

  • Significant pain relief

  • Improved movement and function

  • Long-lasting results β€” implants typically last 15–20 years or more with proper care

  • Improved quality of life and independence

⚠️ Risks and Considerations

  • As with any major surgery: risks include infection, blood clots, fracture, stiffness, nerve or vessel damage, or implant loosening

  • Recovery requires commitment to physiotherapy

  • May not allow high-impact activities (e.g. running or jumping)
