Advantages And Disadvantages Of Knee Replacement Process

Do you have severe knee pain, stiffness, or immobility that makes it hard for you to do things? It appears that total knee replacement surgery is an option for you. Arthritis is the most common of a number of medical conditions that may necessitate knee replacement surgery. Other factors include obesity, developmental abnormalities, some kind of injury, and genetics. Patients who have tried weight loss, lifestyle changes, anti-inflammatory medications, cortisone injections, and other non-surgical methods to alleviate knee pain without success can greatly benefit from knee replacement surgery.


An artificial metal or plastic part called an “implant” or “prosthesis” is used to replace the severely diseased or damaged surfaces of an arthritis knee. This procedure is also known as knee arthroplasty. The shape of these man-made (artificial) knee prostheses allows for continued knee movement.

Unicondylar / Partial Knee Replacement (UKR/PKR) and Total Knee Replacement (TKR) are the two primary types of knee replacement surgeries. More than 4.5 million people in the United States are living with a total knee replacement surgery, according to the most recent data presented this year at the annual meeting of the American Academy of Orthopaedic Surgeons (AAOS). The United States performs approximately 130,000 replacement surgeries annually, according to some estimates.

Surgical Overview 

A total knee replacement, also known as total knee arthroplasty, is a great option for people who have severely damaged the knee joint, resulting in significant pain, stiffness, and reduced knee function. All three of the knee’s compartments—the medial (inside the knee), the lateral (outside the knee), and the patellofemoral (the front of the knee)—are replaced in this complex but highly successful surgical procedure. Artificial knee surfaces (implants) made of metallic and plastic materials that function similarly to a healthy knee are replaced with arthritis-damaged bone surfaces and cartilage during this procedure.

Need for Replacement Surgery 

Replacement surgery helps people who have osteoarthritis and long-term knee pain problems. This option may be considered by patients who suffer from knee-related movement limitations.

How does a total knee replacement work?

A knee replacement requires surgery. Plastic or metal prostheses are used to replace the diseased or damaged portion of the knee during the procedure. The knee as a whole is replaced in total replacement.

How the knee works and how replacement helps?

The knee joint is important for the flexibility and movement of the lower limbs. The pivot is what connects the lower leg’s bones to the thigh bone. Total replacement involves removing the upper end of the lower leg bone at the same time as well as the end of the thigh bone and replacing it with a shell that has already been designed. A piece made of plastic and a metal stem take its place. Behind the knee cap is a button lie structure. This completes the normal knee replacement prosthesis. Polyethylene takes the place of the ligaments that stabilize the lower leg. The most significant risk is the formation of blood clots that can travel as far as the lungs. 

Benefits of knee replacement surgery

  • Urinary tract infections, nausea, knee stiffness, and pain are additional dangers.
  • Additionally, damage to nerves and joint bleeding are possible.
  • Care before and after surgery Antibiotics are given to patients prior to surgery to reduce risks. 
  • Additionally, vital parameters are monitored to prevent postoperative complications.
  • Preoperative care includes reviewing medications taken and routine blood tests.


It is a fundamental part of post employable consideration. Occasionally, a continuous passive motion machine is used to move the knee in a variety of ways automatically while patients relax. This prevents knee stiffness and increases blood flow. Patients learn how to use their knee joints with the help of physiotherapy. The calf and thigh muscles can be strengthened with exercises. Until they are able to walk on their own, patients begin walking with the assistance of walkers and crutches. Patients’ continued participation in the exercises is crucial. Additionally, they must carefully look for signs of infection in the wound.

How to look after replaced joints?

Replaced joints need to be looked after. The new joint can only be used for activities that do the least amount of damage. While recreational sports can be enjoyed, contact sports should be avoided. Patients who are severely restricted in their range of motion as a result of knee joint degeneration, damage, trauma, or arthritis should consider having a total knee replacement. A knee replacement can restore mobility and agility, enabling a more active lifestyle with proper care.


A successful total knee replacement can significantly improve your quality of life and offer numerous advantages. This surgery completely eliminates the knee’s instability, disability, and limited mobility issues. The surgery reduces or even eliminates pain significantly for the patient. The majority of the patients’ knee range of motion can be restored following surgery.

The patient will experience improved muscle strength and improved alignment of deformed joints following the surgery. The pain-free knee enables the patient to maintain a wide range of daily activities, including climbing stairs, shopping, and getting in and out of chairs. A synthetic knee might last a long time. Thanks to the most recent technologies, approximately 95% of knee replacements last 15 years or longer.


Blood clots can form in the legs and spread to the lungs (pulmonary embolism), resulting in chest pain, shortness of breath, and even shock. A urinary tract infection, nerve damage, and blood vessel injury are additional risks associated with total knee replacement. Following surgery, one may experience nausea and vomiting, swelling, persistent knee pain and stiffness, and bleeding into the knee joint. Additionally, the knee may become infected in some instances, necessitating hospitalization and a second surgery.


The high cost at knee replacement hospital is one of its biggest drawbacks. It’s possible that getting a total knee replacement will cost a lot of money. However, the cost of the surgery varies based on the surgeon’s expertise and experience, the kind of implant used, the length of the procedure, the hospital, the medications used, any special tests performed, and your insurance coverage.
