knee Replacement - Dubai Orthopedic Clinic

A way to restore the diseased knee

The surgery for knee replacement is done for restoring the weight-bearing structure of a damaged, diseased or worn knee joint.
It is also known as knee resurfacing or knee arthroplasty. The knee replacement procedure is considered the expert treatment for sports injuries. The surgery restores the function as well as the alignment of the knee.

Common Reasons for Knee Replacement Surgery

  • Osteoarthritis: This age-related arthritis is caused due to the normal wear and tear of the knee joint.
  • Post-traumatic arthritis: This arthritis is caused due to a serious knee injury which leads to tearing off of the ligaments or breaking of the knee, affecting the knee cartilage.
  • Rheumatoid arthritis: This inflammatory arthritis is caused due to thickening and inflammation around the membrane of the knee joint.

The knee replacement is suitable for patients who:

  • Experience severe pain or stiffness in the knees, making it difficult for them to carry out the daily activities such as walking, climbing stairs, etc.
  • Experience moderate to severe knee pain which continues even at the time of sleeping.
  • Experience chronic knee pain which shows no improvement despite the medication.
  • Experience a noticeable deformity in the knee caused either inside or outside the knee. 

Types of knee replacement procedures:

The knee replacement procedure can be either total or partial:

Total knee replacement

Here, both the sides of the knee joint are replaced with surgery. This surgery is one of the most common procedures and takes 1-3 hours. With the surgery, the intensity of the pain will decrease and the mobility will become better.

Partial knee replacement

During this procedure, only one side of the knee is replaced. Since less bone is wiped out, the incision is usually smaller. It is suitable for patients who have damaged only one part of the knee. 

Preparing for the knee replacement surgery:

  • After the diagnosis, and decision about undergoing the knee replacement surgery, some pre-operative preparation is required in terms of the physical evaluations that must be conducted at least a month prior to the surgery.
  • The preparatory tests will include carrying out ECGs, checking the blood pressure and the blood clots, and conducting urine tests.

During the surgery:

During the surgery, the surgeon removes the damaged bone and the cartilage and then uses metal, plastic components, or implants for forming a capping for the knee joint which is shaped as the joint. This helps in the smooth movement of the degenerated knees of the patients.
