What is Knee Replacement Surgery?

The Knee bones have a soft tissue called cartilage. When the cartilage wears off, it causes wear and tears in the joints. This leads to pain and inflammation around the knees.

In a Knee Replacement Surgery, parts of the knee bone are shaved off and replaced with different kinds of implants depending on the severity of osteoarthritis in the knee and the patient’s age itself.

Types of Knee Replacement

Partial/Unicondylar knee replacement

When only the inner middle portion of the knee is worn off due to wear and tear, a partial knee replacement surgery is done. Only a portion of the knee joint is shaved off and replaced with an implant.

Single knee replacement

If only one side of the knee is affected by arthritis, a single knee replacement surgery is done.

Total knee replacement

If both knees are affected because of arthritis, a total knee replacement surgery is done. Here, an artificial prosthesis is fitted in both the knee joints.

Staged knee replacement

In staged knee replacement, each knee is operated several months apart. This gives more time for recovery in each knee for elderly patients

Simultaneous knee replacement

In simultaneous knee replacement, both the knees are operated at the same time. Dr.S. Arumugam is an experienced doctor and therefore, this procedure can be done without a hiccup.

Who will require to undergo Total Knee Replacement Surgery?

Patients don’t need to resort to a Knee Replacement Surgery unless the pain becomes unbearable. People with extreme knee pain will need help getting up and walking even short distances. Sometimes, patients might also start showing severe deformities in the knee due to arthritis.

When this is the case, surgery is the only option. If a patient is experiencing lesser pain, they can be treated with alternate methods like vitamin tablets and injections.

Does Replacement Surgery hurt?

Knee Replacement Procedure has been the most successful procedure for 30 years. Patients can begin walking, squatting, and climbing up the stairs without any pain in about 2-3 months.

They can remain pain-free thereafter with regular exercise and walking.

What Are Some of the Non-Surgical Alternatives for Knee Pain?

Exercise: For initial stages of arthritis, maintaining a healthy lifestyle and exercising regularly strengthens muscles and helps relieve the pain. You don’t even have to take painkillers to relieve yourself of the pain.
Vitamin supplements: When arthritis hasn’t progressed much, vitamin supplements can be used to rebuild the cartilage and reduce the pain caused due to the wear and tear.
Arthroscopy: Here an instrument called an arthroscope is used to get a video feed of the knee and can be used to treat cartilage damage.
