Conditions That Lead to Knee Replacement

  • Osteoarthritis

Osteoarthritis is the most common cause of knee replacement surgery. It causes cartilage breakdown, leading to pain and stiffness.

  • Rheumatoid Arthritis

Rheumatoid Arthritis can severely damage knee joints over time.

  • Knee Injury or Trauma

Sports injuries, fractures, or ligament damage can lead to long-term knee degeneration.

  • Chronic Knee Pain

Persistent pain that affects walking, climbing stairs, or sleeping may require surgical intervention.

Types of Knee Replacement Surgery

  1. Total Knee Replacement (TKR)

In a total knee replacement, the entire knee joint is replaced with prosthetic components. This is the most common type of knee surgery.

  1. Partial Knee Replacement (PKR)

Only the damaged portion of the knee is replaced. This option is suitable for patients with limited joint damage.

  1. Bilateral Knee Replacement

Both knees are replaced either simultaneously or in separate procedures.
