Knee Replacement

Different approaches are available depending on patient needs and the extent of damage:

• Total Knee Replacement (TKR): All compartments of the knee are resurfaced.
• Partial Knee Replacement (PKR): Only the damaged portion is replaced, preserving healthy structures.
• Revision Knee Replacement: A failed or worn-out implant is replaced.
• Robotic-Assisted Knee Replacement: Uses 3D imaging and precision-guided tools for highly accurate implant placement.

Knee replacement is typically recommended when conservative treatments (medications, physical therapy, or injections) no longer provide relief. Common indicators include:

• Severe osteoarthritis, rheumatoid arthritis, or post-traumatic arthritis leading to chronic pain and stiffness.
• Knee deformities such as bowlegs or knock-knees.
• Difficulty walking, climbing stairs, or performing daily activities.

Joint instability, persistent inflammation, or disabling pain that significantly affects quality of life.

Preparation is key to successful outcomes. Steps include:

• Medical evaluation with blood tests, X-rays, or MRI.
• Adjusting medications (e.g., stopping blood thinners).
• Pre-surgery physiotherapy to strengthen muscles and improve flexibility.

Making home modifications such as support rails, stable chairs, or assistive walking devices.

• Performed under general or spinal anesthesia, usually lasting 1–2 hours.
• An incision is made in the knee, and damaged cartilage and bone are removed.
• Artificial implants are placed and aligned to replicate natural motion.
• A dressing or knee brace is applied immediately after surgery.
  

Recovery varies by individual but generally follows this path:

• • Patients begin walking with support within 24 hours.
  • Stair climbing training and restroom independence are encouraged before discharge (2–4 days).
  • Physical therapy starts early, focusing on strength and flexibility.
  • Initial healing: 6 weeks; normal activities: 3 months; full recovery: 6–12 months.
  • High-impact activities (running, jumping) are discouraged to prolong implant life.

• Long-term pain relief and improved mobility.
• Restoration of joint function, stability, and alignment.
• Correction of deformities and prevention of further joint damage.
• Enhanced independence and ability to enjoy low-impact activities.
  

Like all major surgeries, knee replacement carries some risks, including:

• Infection or blood clot formation.
• Implant loosening or wear over time.
• Nerve or blood vessel injury.
• Reduced range of motion or stiffness.
  

Fortunately, success rates are high, and most implants last 15–20 years or more.
