Knee Replacement Surgery (Total Knee Arthroplasty)

A surgical procedure to replace a damaged knee joint with an artificial one. The knee joint is a complex hinge joint that allows for bending, straightening, and twisting.

• Severe Knee Arthritis: When conservative treatments (pain medication, physical therapy, assistive devices) fail to provide adequate relief from persistent and worsening knee arthritis symptoms.
• Other Conditions: Knee replacement may also be considered for other conditions such as:
  • Severe knee injuries
  • Avascular necrosis (bone death)
  • Tumors

• Anesthesia: General anesthesia or spinal anesthesia is typically used.
• Incision: The surgeon makes an incision around the knee joint.
• Removal of Damaged Bone and Cartilage: The damaged bone and cartilage are removed from the femur, tibia, and kneecap.
• Implantation: The artificial components are implanted:
  • Metal components: Replace the surfaces of the femur and tibia.
  • Plastic spacer: Placed between the metal components to allow for smooth gliding.
  • Patella component: (Optional) May be replaced as well.

• Hospital Stay: Typically a 1-2 day hospital stay.
• Physical Therapy: Extensive physical therapy is crucial for regaining strength, flexibility, and range of motion. This may involve exercises to improve walking, balance, and daily activities.
• Weight-Bearing Restrictions: Weight-bearing restrictions may be necessary for a period after surgery.
• Return to Activity: A gradual return to normal activities is recommended, with full recovery often taking several months.
