What is Knee Replacement Surgery?

Arthroplasty, which is a new knee joint, is considered a major surgery. Usually, this operation is recommended to the people who have these three ailments í) arthritis, ii) trauma, and iii) other degenerative diseases leading to severe knee pain and loss of function.

It might be that you experience extreme stiffness, swelling, or instability in your knee.
Severe joint destruction is seen on X-rays.
Considering the elements of age, general health, and activity level is very important. Moreover, it is necessary to debate how a knee replacement can lead to a patient’s better life experience as a result of suffering from severe knee pain.
The information on how to make a decision on whether knee replacement is the best option, and the significance of getting a second opinion if required.

The Different Types of Knee Replacement Surgery

Knee replacement surgery is an individualized treatment. The kind of surgery suggested is largely dependent on how the knee is damaged and the patient’s other characteristics. In this sense, it would clarify the different surgical alternatives for knee replacements. A brief coverage of them might be:

Total Knee Replacement (TKR)

As indicated in the name, the most frequent operation is total knee replacement, whereby the entire knee joint is changed. The physician removes the damaged surfaces of the femur and tibia in addition to the metal and plastic components. The surface of the kneecap (patella) may also be newly made. Usually, TKR is advised for patients who present with extensive knee damage.

Partial Knee Replacement (PKR)

The portion of the knee that is damaged is the only one replaced. The procedure is called unicompartmental knee arthroplasty and is performed when the rest of the knee is healthy except for one part. The surgeon removes the ligaments and cartilage that are affected by the disease and replaces that part with a new compartment (the inside, the outside or the kneecap area). The surgery can be proposed to patients who are young or with damage that is localized in the joint.

Robotic-Assisted Knee Replacement

Robotic-assisted knee replacement is one of the high-tech surgical methods where a robotic arm or system is used to increase the skill of the surgeon during the operation. It is usually followed by a detailed 3D modeling of the patient’s knee created from the CT scan.

Minimally Invasive Knee Surgery

Minimally invasive knee surgery uses smaller cuts than the standard surgery of knee replacement, and, therefore, the surgeon can reach the joint with a method that reduces the disruption of the muscles and soft tissues.

How to Prepare for Your Surgery

Before you go to have a knee replacement surgery, it is really crucial that you consult in detail with your orthopedic surgeon. In fact, this is the time when you can check all your uncertainties and get the confirmation that you have taken the proper decision. Some of the issues around which the discussion may be are:

Evaluate your knee through physical examination that tests the range of motion, stability and general condition of the knee.
It is really necessary to perform a physical exam that would evaluate the knee’s range of motion, stability, and general condition. Inquire about your medical history and any drugs that you have taken.
Discuss in detail the implant, the surgical method, along with the potential risks and benefits.
Providing your questions about pain management, recovery, and long-term prognosis.
Supporting you in making realistic goals that you will be able to reach after the surgery.
Knowing your doctor’s expertise and achievements.
Test and assessment before surgery (blood sample, EKG., etc.).
Definitely, managing diseases that have already been established is very important (diabetes, hypertension, etc.).
One more reason can be that a patient is doing physical therapy or exercising to build up the affected part before the operation.

Procedure of Knee Replacement Surgery Procedure

The procedure for knee replacement surgery is explain in detail step-wise below here:

Anesthesia: To make the patient comfortable during the whole surgery, the patient is administered anesthesia. It may be a general one (when the patient is totally asleep) or a local one (where the numbed area is below the waist).
Incision: The doctor has penetrated through the skin of the knee to have direct access to the joint. How long the cut is depends on the type of surgery (open or minimally invasive) that is used.
Preparation of the Bone: The process has been carried out to eliminate the damage to the femur (thigh bone) and tibia (the shin bone). The doctor then goes about shaping the remaining bone to match the shape of the components of the artificial implant.
Implant Placement: The metal and plastic parts of the knee implant are placed on the prepared bone surfaces. It is at the end of the femur that the femoral component is fixed, while the tibial component is placed on top of the tibia. In addition, for some cases, a plastic spacer is put in between so that the sliding movement can take place.
Patella Resurfacing: The patella (the kneecap) is being reshaped from underneath and a plastic button is attached to it to facilitate the movements of the joint.
Checking Alignment and Movement: The doctor conducts the exercise of moving the knee in all directions to check whether the implant position is correct and stability has been achieved.
Closure: The cut is being closed by using stitches or staples, and then the knee is being bandaged.
Recovery: The patient is sent to the recovery room to be monitored as the anesthesia effect gradually disappears. Early physical therapy is therefore very effective and can start within 24 hours to facilitate healing and regain lost mobility.
