What is knee replacement?

Knee replacement or knee arthroplasty is the surgical procedure to replace a damaged knee. In this process, plastic and metal parts are used to cap and seal the ends of the bones of the knee joint, including the knee cap. An individual with severe knee arthritis or severe knee injury may consider undergoing knee replacement surgery. The aim of knee replacement surgery is to resurface the parts of the knee joint that have been damaged. There are different arthritis that may affect the knee joint such as Osteoarthritis, Rheumatoid arthritis, and Traumatic arthritis.

Physical examination for Knee Replacement


Before the knee replacement surgery, the orthopedic doctor will diagnose the condition of the knee. The doctor will inspect for tenderness, swelling, and pain in the knee. The doctor will also try to push and pull the knee joint and evaluate the damage in the structure of the knee. To diagnose the condition of the knee and the severity of the damage, the doctor may recommend an x-ray, ultrasound, CT scan and MRI.


Not every knee injury needs surgery. In case surgery is required, the doctor will choose the best method out of the following:

1. Partial knee replacement surgery - In partial knee replacement surgery, the orthopaedic surgeon replaces only the damaged part of the knee and replaces it with metal and plastic parts. The surgery is performed through minimal incisions and healing is usually risk-free.

2. Total knee replacement surgery - In a total knee replacement procedure, the damaged bone of the knee including the cartilage, kneecap, shinbone is removed. The removed part is replaced with an artificial joint made of high-grade polymers and metal alloys.

3. Arthroscopic surgery - In this surgical treatment, the surgeon makes a tiny incision and inserts an arthroscope, a tiny camera, into the knee. The doctor views the inside of the knee joint on a monitor screen. With the help of the guiding images, the doctor removes and replaces the damaged parts of the knee.

What are the signs that you need a knee replacement?

Knee arthritis may develop over time and make it difficult for you to carry your daily tasks in a normal manner. By the time you experience difficulty, the damage may already be done to the knee. Important signs that may indicate that you need a knee replacement are:

1. Chronic pain - The pain in the knee may come and go and affect you in different ways. The pain need not always be severe or sharp. If you experience any amount of pain after doing any physical activity or walking even the shortest distance, it is a warning that something is wrong with your knee and that you may need a knee replacement. Other times, the pain could be so severe that it prevents you from falling asleep.

2. Limited movement - If you have difficulty sitting down or if your knee refuses to bend, it is a common indication that you need a knee replacement. Seizing the joint during movement may also be indicative of damage or degeneration of the bone fragment of the knee.

3. Limitations in lifetsyle - Whether you for a morning or simply take a stroll in the garden, if you notice limitations in the ability of your movement, it is a cause of concern. Before the knee deteriorates and brings your lifestyle activities to a halt, you should seek advice from an orthopedic doctor.

Anatomy of the knee

The knee consists of two long bones that are held together by ligaments, muscles and tendons. The end of each bone is covered by a cartilage layer that protects the knee. There are 2 groups of muscles involved in the knee - the quadriceps and the hamstring muscles.

The knee consists of:

  • Tibia - The shin bone or the larger bone of the leg
  • Femur - The upper leg bone
  • Patella - The kneecap
  • Cartilage - Tissue that protects the surface of the knee bone
  • Ligament - The connective tissue that surrounds the knee joint
  • Tendon - Teh connective tissue that connects the knee bones and the muscles
  • Meniscus - The curved part of the cartilage that protects the knee joint

How to prepare for knee replacement surgery?

  • Before the surgery, you will have a thorough consultation with the doctor. You can discuss everything about your condition with the doctor.
  • The orthopedic surgeon may perform a complete physical examination to ensure that you are fit for the surgery.
  • If you are sensitive or allergic to any medications, inform the doctor.
  • If you have a history of any underlying disease or bleeding disorders, it is important for you to stop taking the medications immediately.
  • If you are pregnant, inform your doctor.
  • The surgeon may ask you to stop eating anything for at least 8 hours before the surgery.
  • Arrange someone to take you to the hospital on the day of the surgery and also accompany you while returning back from the hospital.
