Knee joint replacement surgery

Total Knee Replacement is a very common orthopedic operation that replaces the damaged knee joint with an artificial joint that replaces the natural joint and performs its function.

This procedure helps relieve pain and restore joint function and normal range of motion in people with a damaged joint.

People of all ages may need this surgery, but the vast majority of patients are over 50 years old due to joint overload and degenerative joint disease (osteoarthritis).

Overview of the knee joint

The knee joint is one of the largest and most powerful joints in the body, and it is necessary to perform a wide range of movements, such as walking, jumping, and sitting in certain positions.

The joint consists mainly of three bones: the femur, the patella, and the shinbone (tibia). These bones are connected by cartilage, ligaments, and tendons.

As a result of excessive use of the joint (as it contributes to most of the body’s movements), this joint is subject to many diseases and traumatic injuries that affect its function. Knee pain is one of the most prominent complaints that prompt patients to consult an orthopedic doctor.

Among the symptoms that appear when the knee joint is injured are: swelling and redness around the knee, imbalance in the foot, hearing a bone crack when moving the joint, Joint stiffness.

In cases of severe injury to the knee joint, which manifests as severe pain that does not respond to drug treatments or through limiting the range of movement of the joint, then the operation to completely change the knee joint can be resorted to.

 When is the knee replacement surgery performed?

 The most common reason for knee replacement surgery is degenerative arthritis (osteoarthritis), the most common type of arthritis. This disease causes degenerative changes that erode the cartilage and subsequently cause a change in the shape of the bone.

These changes usually develop slowly and worsen over time, as the patient feels increasing pain and stiffness that may develop into a dysfunction that manifests as a weakness in the ability to move, which prevents the patient from carrying out his daily activities such as walking and climbing stairs.

Severe pain and inability to accomplish daily tasks requires surgery to improve the person's life and rid him of the pain he suffers from.

There are other reasons for knee replacement surgery, including:

  • Rheumatoid arthritis (rheumatism)
  • Congenital anomalies that impede movement
  • gout
  • The bones in the knee joint die due to ischemia
  • Diseases that lead to abnormal growth of the knee bones

The surgeon sets aside the patella in order to reach the damaged articular surfaces of the femur and tibia. The end of each of these bones is carefully cut.

A flat metal plate and a piece of plastic are placed at the end of the tibia, and a curved metal plate is attached to the end of the femur, thus forming an artificial joint between the ends of both bones.

This procedure has a high success rate and is considered fairly safe, especially if it is performed by an experienced orthopedic surgeon.
