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. To get relief from long term knee pain and stiffness, get in touch with Pristyn Care and book Discounted consultation with the best knee replacement surgeons in Delhi NCR.

Treatment

Diagnosis Before Knee Replacement Surgery

Before undergoing knee replacement surgery, patients typically complete a thorough diagnostic process to assess the severity of their condition and confirm that surgery is the most appropriate course of action. Common evaluations include:

Medical History and Physical Examination – The orthopedic surgeon reviews the patient’s medical history—symptoms, prior treatments, and underlying conditions—and performs a comprehensive physical exam of the knee to evaluate range of motion, stability, strength, and signs of joint damage.
Imaging Tests – Imaging helps determine the extent of knee damage and aids surgical planning. X-rays can reveal bone abnormalities, joint space narrowing, and alignment issues. MRI (Magnetic Resonance Imaging) may be used to visualize soft tissues such as cartilage and ligaments and detect additional problems.
Joint Aspiration – In selected cases, fluid may be removed from the knee joint (aspiration) for laboratory analysis to identify signs of inflammation, infection, or other underlying conditions.
Functional Assessment – Functional tests—such as gait analysis—evaluate mobility, identify movement limitations, and reveal compensatory mechanisms that may impact treatment planning and recovery.

Knee Replacement Surgery

Knee replacement typically involves the following steps:

Before the surgery begins, the patient is given general anesthesia to ensure they are comfortable and pain-free throughout the procedure.
Once the anesthesia has taken effect, the surgeon makes an incision over the knee joint, typically 6 to 10 inches long, to access the damaged knee components.
The type of incision may vary depending on the surgeon’s preference and the patient’s anatomy.
The surgeon carefully removes the damaged portions of the knee joint, including the diseased cartilage and bone, using specialized surgical instruments. This step aims to prepare the knee for the placement of artificial implants.
The surgeon removes the damaged tissues and proceeds to place the artificial components that will replace the natural structures of the knee joint. This usually involves attaching metal implants to the ends of the femur (thighbone) and tibia (shinbone).
In some cases, the undersurface of the patella (kneecap) may be resurfaced with a plastic component to improve joint function and reduce friction.
Once the artificial implants are securely in place and the knee joint is realigned, the surgeon closes the incision with sutures or staples. Sterile dressings are applied to the surgical site to promote healing and prevent infection.
After the surgery, patients are monitored closely in the recovery room before being transferred to a hospital room or outpatient facility. Physical therapy and rehabilitation play a crucial role in the recovery process, helping patients regain strength, flexibility, and mobility in the operated knee.

What are the different kinds of knee implants or prosthesis?
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.
