What is Knee Replacement Surgery?

Knee replacement surgery, also known as total knee replacement or knee arthroplasty, is a minimally invasive surgical procedure to resurface the damaged knee joint. This surgery is suggested by orthopedic surgeons for patients who have severe arthritis, bone tumor, or severe knee injury.

The goal of minimally invasive knee replacement surgery is to resurface the parts of the knee joint which have been damaged and to relieve chronic or constant knee pain which cannot be controlled by other non-surgical treatments. Unlike traditional total knee replacement, minimally invasive knee replacement surgery is apt for all patients. Consult highly skilled orthopedic surgeons at Pristyn Care who specialize in minimally invasive orthopedic surgeries such as total knee replacement, hip replacement, etc. 

Knee replacement surgery is a common yet major orthopedic surgery that is used to replace the damaged or worn-out surfaces of the knee. During the surgery, the orthopedic surgeon will replace these damaged or worn-out surfaces with an implant. This will relieve pain and maximize mobility, allowing increased knee motion.

Knee Replacement Surgery

The minimally invasive knee replacement procedure involves the use of modified techniques and surgical instruments to place the clinically proven implants through a small incision. The minimally invasive knee replacement surgery is performed through 1 small of 3- to 4-inch incision instead of a larger incision of 8- to 12-inch, as in case of the traditional surgery for knee replacement.

Potential benefits of minimally invasive knee replacement surgery include increased knee mobility and motion sooner after the surgery, lesser blood loss during the surgery, faster and easier recovery, much smaller scar and shorter hospital stay.

In Our Doctor's Word

Dr. Ashish Taneja

MBBS, MS - Orthopaedics

17 Years Experience

"Knee replacement surgery is one of the most delayed surgical procedures. Patients delay it until they can barely walk or bones start cracking. A common sentiment is, "I thought it was Ok, as long as I could walk" or "My friends told me yoga could help". Well, while yoga and other exercises can help prevent certain diseases, an unmonitored strain during an already severed arthritis, does more damage than good. It may severe the pain, and advance complications. This is why I always highlight the importance of timely treatment. Then, you'll able to recover quicker, adjust faster, walk painlessly and experience a very evident change in the quality of life. Also its a myth that the implants only last 5-6 years. No. A good knee replacement surgery will easily last you an average of 15-25 years."

What are the different kinds of knee implants?

Generally, a knee implant is made of four components, i.e., a tibial component, a femoral component, a patellar component, and a plastic spacer. Based on their components, knee implants can be categorized as:

  • Metal on plastic: In this type of implant, a metal femoral component is attached to a plastic tibial component. It is the most common, least expensive kind of implant. However, these implants are not preferred as much now because the particles released due to wearing away of the plastic component can trigger an immune response in the future.;
  • Ceramic on plastic: These implants feature a ceramic femoral component on a plastic tibial component. It is used in people who might have an allergy to metal implants. However, they are not preferred for the same reason as the metal on plastic implants.;
  • Ceramic on ceramic: In these implants, both components are made of ceramic. They are least likely to trigger an immune response. However, they are not preferred as much because they make a squeaking noise when the patient is walking. Also, they can easily shatter when subjected to very heavy loads.;
  • Metal on metal: In these implants, both components are made of metal. These are not widely in use as they release small amounts of metal in the bloodstream as they erode, which can cause inflammation, pain, and even permanent organ damage in the long term.
