artificial joint replacement surgeries

What are artificial joint replacement surgeries?

Artificial joint replacement surgery is a procedure in which the damaged parts of a joint are removed and replaced with artificial components designed to mimic the movement of a natural joint, reducing pain and improving mobility. It is often performed in cases of advanced osteoarthritis or when conservative treatments have failed.


The most common types of joint replacement:

  • Total Knee Replacement: The damaged surface of the femur, tibia, and patella is replaced with metal and plastic components.
  • Total Hip Replacement: The femoral head and pelvic socket are replaced with a metal/ceramic artificial joint.
  • Shoulder Replacement: Used to treat severe damage or large, irreparable tears.

Less commonly, joint replacement surgeries can also be performed on the ankle, elbow, and fingers.


Components of an Artificial Joint:

  • A metal component that is fixed to the bone.
  • A special plastic lining to reduce friction.
  • Sometimes ceramic components for increased durability.

These components are fixed either using medical-grade bone cement or techniques that allow the bone to fuse directly to the joint.


When is surgery recommended?

  • Severe, persistent pain that interferes with daily life
  • Failure of medication and physical therapy
  • Significant deformity or severe limitation of movement
  • Impaired sleep or ability to walk

Benefits of surgery

  • Significant pain relief
  • Improved mobility and walking ability
  • Improved quality of life

Potential risks

  • Wound infection
  • Blood clots
  • Joint stiffness
  • Loosening or wear of the artificial joint over time

Recovery time

  • Assisted walking within a few days
  • Physical therapy for several weeks
  • Full improvement is usually seen within 3–6 months. The lifespan of an artificial joint is typically 15 to 25 years, depending on usage and the type of joint.
