Knee Replacement, also known as arthroplasty is a common bone reconstruction surgery that can help ease the pain and improve movement. During surgery, the joint replacement surgeons carve away the damaged part of the knee and replace it with an artificial joint made of metal or plastic, which is then attached to the thigh bone, shin, and kneecap. Total Knee Replacement is effective and safe. Only in rare cases, patients need readmission.

What is Knee Pain?

It is a pain that is felt in or around the knee and indicates a condition that affects the knee joint itself or the soft tissue around the knee.

What are the Common Causes of Knee Pain?

  • Sudden injury
  • Overuse injury (sprains or strains)
  • Heavy physical activity
  • Sitting in a constrained area or on knees for a prolonged period
  • An underlying condition, such as arthritis

Treatment will vary depending on the cause. Knee injury is likely to cause pain, swelling, and stiffness.

What is Knee Replacement Surgery?

The knee joint comprises the kneecap or patella, the thigh bone, and the leg bone. Each end is covered with articular cartilage. The latter is an elastic material that permits the knee to move well. If damaged, the cartilage is incapable of repairing itself. Knee replacement surgery or total knee replacement, which is also popular as knee arthroplasty is recommended to the patient by the specialist doctor. It is a well-established surgical treatment. The procedure helps resurface knees damaged by arthritis.

There are several benefits of knee surgery. It helps in relieving pain and restoring function of the knees. During surgery, the joint replacement surgeon carves away the damaged part of the knee and replaces it with an artificial joint made of metal or plastic, which is then attached to the thigh bone, shin, and kneecap with something like acrylic cement.

Knee replacement can be successfully done in an obese patient as well

What are the Different Types of Knee Replacement Surgery?

Some of the major knee replacement surgeries are:

Total Knee Replacement or TKR is the most common type of knee surgery. In this type, both sides of the knee joint are replaced. The patient experiences less pain and improved mobility. Scar tissues may make it challenging to move and/or bend the knees.

Partial Knee Replacement replaces one part of the knee. It is an alternative to TKR for some patients suffering from osteoarthritis. The surgery can be done when the damage is in a specific compartment of the knee.

Kneecap Replacement replaces the inner part of the kneecap. It is effective for people with severe kneecap arthritis.

Complex Knee Replacement for those who require two or more knee surgeries. It helps ease severe or chronic arthritis.

Why is a Total Knee Replacement Surgery needed?

  • Osteoarthritis: The main objective of knee replacement surgery is to eliminate the pain and movement disorders caused by Osteoarthritis. A very common old-age problem, Osteoarthritis occurs when cartilage, the cushion between the knee and the bone joints, breaks down.
  • Rheumatoid Arthritis: When the body’s immune system attacks and destroys the lining of the knee thus causing severe pain
  • Deformities: People with bowed legs or “knock-knees” may need surgery to restore the knee position
  • Knee Injuries: A broken bone or torn ligaments around the knee may result in arthritis. Surgery can help in alleviating pain and restoring movement
  • Loss of Blood Flow: Doctors will recommend surgery if knee damage causes a halt in blood flow to the bones (a condition called either osteonecrosis or avascular necrosis)

Who is a Candidate for a Knee Replacement?

Knee surgery is suitable for patients experiencing:

  • Severe pain or knee stiffness that does not allow them to do daily activities like walking.
  • Moderate but continuous pain that persists even when resting or sleeping.
  • Chronic knee swelling or inflammation. The condition does not get better despite taking medication.
  • Knee conditions, wherein a noticeable arch or defect lies on the outside/inside the knee.

How long do they Last?

When replacement surgery first started in the early 1970s, the artificial joints were expected to last for about a decade. Now, however, modern implants can last as long as 20 years.

COMMON QUESTIONS

Risks associated with knee surgery are rare and can be addressed. Possible complications may include infection of the wound, treatable with antibiotics. The wound can sometimes become infected and need further diagnosis and treatment. Risks associated with knee surgery can include:

  • Blood clotting in lungs or leg vein
  • Infection
  • Heart Attack
  • Nerve Damage
  • Stroke
  • Risk of infection

Notify the doctor in case of the following symptoms:

  • Fever higher than 37.8 C or 100 F
  • Surgical site draining
  • Shaking chills
  • Increased tenderness, redness
  • Knee pain and swelling

Here are the top ways a patient can prepare for a knee replacement surgery:

  • Selecting the best surgeon should be the target. Taking recommendations from those who have undergone TKR and physicians can help. It is also a good idea to go through reviews available on trusted sites.
  • Undertaking preoperative preparations as knee arthroplasty is major surgery. Preoperative preparations and physical evaluations must start a month before the surgery.
  • Do exercises for increasing your upper body strength. These exercises will help to cope with post-surgery stress.
  • Taking pre-and post-surgery recommendations from the surgeon can be a good start. Knowing devices to provide support and improve mobility is also necessary.
  • Ask about home safety aspects. These include bathroom handrails, non-sliding rugs, relocating electric equipment, etc
  • Being Transparent and open to communications with the surgeon is a must. Discuss the current emotional state, know what to expect, and how to prepare better for TKR.
  • It is advisable to visit your dentist before surgery. Avoid dental procedures at least six months before surgery.

The usual time it takes to properly recuperate following knee replacement surgery is six to twelve months before returning to physically demanding activities. Despite the fact that the recovery process can be lengthy, there are steps you can do to ensure a speedy recovery.
