Overview

Published with the inputs from Dr Nikhil C S, Orthopaedic And Arthroscopic Surgeon, Baby Memorial Hospitals- Kozhikode

Total Knee Replacement (TKR) is a surgical procedure to replace the damaged or worn-out surfaces of the knee joint with artificial components called prostheses. It is usually performed for patients with severe arthritis, injury, or joint deformity who experience persistent pain, stiffness, and difficulty walking. TKR helps restore mobility, relieve pain, and improve overall quality of life.

What is total knee replacement (TKR)?

TKR is a surgery in which the damaged cartilage and bone from the surface of the knee joint are removed and replaced with metal and plastic implants that replicate the movement of a healthy knee joint.

When is total knee replacement recommended?

Your doctor may recommend TKR if you have:

  • Severe knee pain that limits daily activities (walking, climbing stairs)
  • Osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis
  • Knee deformity (bowing or knock-knee)
  • Failure of conservative treatments such as medications, injections, or physiotherapy
Is total knee replacement safe?

Yes. TKR is one of the most successful and safe orthopaedic surgeries worldwide. With modern anesthesia, infection control, and advanced surgical techniques, the complication rate is extremely low, especially when performed by experienced orthopaedic surgeons.

How is total knee replacement performed?
  • The surgery is done under spinal or general anesthesia.
  • Damaged portions of the femur (thigh bone) and tibia (shin bone) are removed.
  • Artificial implants made of metal alloys and high-grade plastic are fixed to restore smooth joint movement.
  • The procedure typically takes  around 2 hours.

At BMH, minimally invasive and robotic-assisted TKR options are available for superior precision and faster recovery.

What is recovery like after total knee replacement?
  • Hospital stay: 3–5 days
  • Walking: Usually begins within 24 hours with assistance
  • Physiotherapy: Starts immediately to improve motion and strength
  • Return to daily activities: 4–6 weeks
  • Full recovery: Around 3–6 months, depending on individual health and rehabilitation progress
How long does a knee implant last?

Modern knee implants typically last 15–20 years or more, depending on factors such as activity level, body weight, and implant material. Advances in implant technology and surgical precision have improved longevity.

What are the benefits of total knee replacement?
  • Relief from chronic knee pain
  • Improved joint movement and flexibility
  • Ability to walk, climb stairs, and perform daily tasks comfortably
  • Enhanced posture, stability, and overall mobility
  • Long-term improvement in quality of life
Are there risks or complications after TKR?

Minor risks such as infection, stiffness, or blood clots may occur but are rare. With proper care, physiotherapy, and medical supervision, patients typically enjoy excellent long-term outcomes.

What lifestyle changes are recommended after TKR?
  • Maintain a healthy body weight
  • Follow a regular physiotherapy and exercise program
  • Avoid high-impact activities (running, jumping)
  • Use supportive footwear and assistive devices as advised
