Hip & Knee Joint Replacement

What is Hip & Knee Joint Replacement?

A hip or knee joint replacement is surgery to remove and replace a damaged or arthritic joint with a prosthesis or artificial joint. This may be considered only when other treatment options to improve function or relieve pain have failed.

Joint replacement is recommended where there is severe pain that limits activity and does not respond to nonsurgical medical management. There would also be an area of bone-to-bone contact in the weight-bearing joint.

With a total or partial knee replacement, the joint surfaces, not the bone would be replaced. One or more of the knee’s three compartments would be replaced with an artificial surface made of plastic and metal in a total knee replacement. These compartments are found inside, underneath, and outside of the knee cap. A partial knee replacement involves only one of the compartments.

For hip replacement surgery, damaged cartilage and bone will be removed from the hip joint to be replaced with artificial parts. The incision may be made on the back, front, or side of the hip.

What are the possible complications associated with Joint Replacement?

  • Wound infection
  • Infection around the artificial joint
  • Nerve injury in the surrounding areas. This is rare but may occur
  • Possible malfunction of the prosthesis from wear and tear, breakage, dislocation, or loosening
  • Blood clots 

Preparing for a Joint Replacement

As with any surgery, here are a few things to keep in mind:

  • Medication
    Inform your doctor about the medication you are on. You might need to stop the medication for a brief period until after the surgery.
  • Planning Your Discharge
    Discuss with your doctor about taking care of the incision, pain medication, special exercises, and home care arrangements.
  • Rehabilitation
    Exercises for rehab can contribute to restoring function, mobility, and strength to the affected joint and surrounding muscles.
