What is Knee Replacement Surgery?

Total Knee replacement surgery or knee arthroplasty is a surgical procedure that helps to relieve pain and restore function in knee joints, that are damaged by arthritis, and cannot be controlled by other treatments.

The total knee replacement procedure includes cutting away damaged bone and cartilage from the thigh bone, shinbone and kneecap to replace it with an artificial joint called a prosthesis which is made of metal alloys, high-grade plastics, and polymers.

A surgeon can best assess the knee’s range of motion, stability, and strength through physical examination and with help of X-rays to determine whether Knee Replacement is a viable option for you.

Reasons for the Knee Replacement Procedure

Various types of arthritis can affect the knee joint:

Osteoarthritis
Rheumatoid arthritis
Traumatic arthritis

Osteoarthritis causes the breakdown of joint cartilage, leading to damage of the cartilage and bones limiting the movement and causing pain.

Acute degenerative joint disease can cause pain and swelling, making it difficult for people to do normal activities that include bending the knee like walking or climbing stairs.

Knee replacement surgery is generally done as a treatment to relieve pain and disability in the knee. The most common cause of knee replacement surgery is osteoarthritis.

In some cases, a knee injury can cause rheumatoid arthritis and arthritis leading to a degeneration of the knee joint. Moreover, fractures, torn cartilage, and torn ligaments may sometimes lead to irreversible damage to the knee joint.

Knee replacement surgery can prove to be an effective treatment when other treatment options like anti-inflammatory medication, physical therapy, and cortisone injections into the knee joint fail to alleviate the pain.

Anatomy of the Knee Replacement

Before we try to understand the Knee replacement procedure, it is important to understand the anatomy of the knee.

The knee consists of:

Tibia, the shin bone or larger bone of the lower leg.
The femur, the thigh bone, or the upper leg bone.
Patella, also known as the kneecap.
Cartilage, a type of tissue covering the surface of a bone at a joint, helps to absorb shock and protect the knee and reduce movement within a joint.
The synovial membrane is a tissue lining the joint and sealing it into a joint capsule. It also secretes synovial fluid which is a clear, sticky fluid found around the joint to lubricate it.
Ligaments are a type of strong, elastic bands of connective tissue that surround the joint to give assistance to the knee and to help limit the joint’s movement. It connects bone to the bone.
Tendon, the tough cords of connective tissue that connect muscles to bones and help to control the movement of the joint.
The meniscus is a curved part of cartilage in the knees and other joints that act as a shock absorber, increasing contact area. They help to deepen the knee joint.

Knee Replacement procedure

Before the Procedure:

A complete physical examination is done to ensure the patient is in good health before undergoing the procedure. Blood tests or other diagnostic tests are also performed.
Patients should inform the doctor if they are sensitive or allergic to any medications, latex, tape, and anesthetic agents.
All regular medications being taken by the patient and medical conditions if any should also be conveyed to the doctor.
The patient is asked to fast for eight hours before the procedure.
A sedative is given before the procedure to help the patient relax.
One should also make arrangements before the surgery itself, for someone to help around the house for a week or two after being discharged from the hospital.
The decision about the type of anesthesia to be used is also made after a discussion between the anesthesiologist and the patient.
Intravenous antibiotics are given before, during, and after the procedure to help prevent post-surgical infections.

During the Procedure knee Replacement

Knee replacement surgery is usually performed under general anesthesia. However, all options are discussed with the patient in advance by the anesthesiologist.

The anesthesiologist continuously monitors the heart rate, blood pressure, breathing, and blood oxygen level during the surgery.

The actual procedure of the surgery is as follow:

Step 1: Making the knee incision

An incision of about 8 to 10 inches long is made by the surgeon across the front of the knee to gain access to the patella or kneecap.

Step 2: Rotating the patella (kneecap)

Once the knee is open, the patella is rotated outside the knee area, allowing the surgeon to view the area needed to perform the surgical procedure.

Step 3: Preparing the femur (thighbone)

The femur known as the thighbone is the first bone to be surfaced. Bones are carefully measured by the surgeon and precise cuts are made using special instruments.

The damaged joint surfaces are cut away. The surgeon then cuts and resurfaces the end of the femur to fit the first part of the artificial knee, the femoral component.

The prosthesis is normally composed of 3 components: the tibial component, the femoral component, and the patellar component

Step 4: Implanting the femoral component

The metal femoral component or artificial joint is then attached to the end of the femur and bone cement is used to seal it into place.

Step 5: Preparing the tibia (shinbone)

The next bone to be resurfaced is the tibia or shinbone. The damaged bone and cartilage are removed from the top of the tibia and then the bone is shaped to fit the metal and plastic tibial components.

Step 6: Implanting the tibial component

The tibial tray, which is the bottom portion of the implant, is fitted to the tibia and secured into place using bone cement.

Once it is in place, the surgeon snaps in a polyethylene insert made of medical-grade plastic to sit between the tibial tray and the femoral component, which acts as a kind of buffer.

This insert will eventually provide support for the body as one bends and flexes the knee.

Step 7: Re-adjusting the patella

The surgeon sometimes needs to flatten the patella before returning it to its normal position and fit it with an additional plastic component to ensure a proper fit with the rest of the implant. The plastic piece is sometimes cemented to the underlying bone if the surgeon feels the need.

Step 8: Finalizing the procedure

The knee is bent and flexed to ensure that the implant is working correctly and to check if the alignment, sizing, and positioning are suitable.

The procedure is completed by closing the incision with stitches or staples, and then bandaging it, and preparing the patient for recovery.

One might leave the operating room with the leg in a CPM (continuous passive motion) machine that gently bends and flexes the new knee while the patient is lying down.

The Total Surgery lasts about two hours.

After the procedure Knee Replacement

The patient is taken to the recovery room for observation after the surgery. The patient is shifted to the hospital room once the blood pressure, pulse, and breathing are stable and the patient is alert. There is a hospital stay of a few days after the surgery.

Starting to move the new joint after surgery is very important. A physical therapist plans an exercise program after the surgery.

The pain is controlled with adequate medication so that the patient is comfortable and can exercise. An exercise plan to follow both in the hospital and after discharge is provided by the physical therapist until one regains muscle strength and a good range of motion.

Home Care

All kinds of falls must be avoided after the knee replacement surgery, as it can result in damage to the new joint. A cane or walker is recommended until the strength and balance improve.

Certain modifications around the home can help one during the recovery. Some of these include:

Handrails along all stairs
Safety bars or handrails in the shower or bath
Using a bench or chair in the shower
Toilet seat riser with arms
Reaching stick to pick objects
Removing all kinds of loose carpets and electrical cords that may cause one to trip or fall

What Not to Do After Knee Replacement?

The knee joints take a lot of battering all our lives, which can ultimately lead to osteoarthritis and various other knee injuries. Designed to rebuild and restore knee function and reduce pain by replacing the knee joint with an artificial one, Knee replacement surgery (knee arthroplasty) is very popular these days, and is helping people resume normal lifestyles.

An important part of recovery following knee replacement surgery is stretching and strengthening of the muscles. But one needs to keep in mind that some types of movements and exercises may be more harmful than beneficial.

It is vital to learn what types of movements should be avoided after a knee replacement surgery.

Exercises and Movements to avoid after a knee replacement

The knee replacement surgery aims at enabling one to return to everyday activities without pain. As tempting as it is to return to a normal routine as soon as possible, there are some exercises and movements one should avoid during recuperation and healing.

Activities with a high risk of falling

Loss of strength, range of motion, and balance lead to an increased risk of falling lost knee replacement surgery. A fall can be damaging to the prosthesis and can deter the healing process.

A few lifestyle changes that can reduce the risk of falling include:

Use the handrail when climbing up and down the stairs
Use a rubber mat or shower chair when taking a bath
Always sit down to put on shorts or pants
Keep the floor clear of toys, slippery mats & rugs, and other items that may present a risk of tripping.
Avoid slippery terrains like mud, ice, or wet grass

Prolonged sitting

The risk of developing a blood clot, especially in the first 2 weeks after surgery is increased due to long duration of sitting, post a knee replacement surgery. It can also hinder the drainage of fluid in the lower leg, making the swelling worse.

It is advisable not to sit continuously for more than 40 to 45 minutes. In case prolonged sitting is unavoidable, prop the legs up on a chair or something similar to minimize swelling.

Excess weight-bearing

Most people use a walker, crutches, or other assistive devices after knee replacement surgery. Early weight-bearing and moving around as soon as possible after surgery is recommended by most surgeons. However, for the initial days, this will need the help of a nurse, a family member, or a physical therapist.

A should be avoided until one is allowed to do so by the surgeon or physical therapist. While climbing up the stairs, lead with the leg that has not had surgery and while climbing down, step first with the leg that has had surgery.

Kneeling: Difficulty in kneeling or an inability to kneel after a total knee replacement is reported by many people. Though there is not much evidence to such that kneeling shortens the life of the prosthesis, if one is uncomfortable, it should be avoided.

Running and Jumping

The knee joint bears three times the normal force while running than when walking. And jumping involves an even higher amount of force at work. One must totally avoid activities that involve running and jumping while recovering from a knee replacement surgery. These activities may not only delay healing but also cause damage to the prosthesis.

In fact, such high-intensity activities should be avoided even when fully healed.

Sports with high impact or quickly changing directions

Here are some sports to avoid after the knee replacement:

Weight training: Heavy weight lifting, particularly during squats or similar exercises, which exert pressure on the joints should be totally avoided. Ask your doctor or physical therapist for suggestions or techniques which are suitable for the new knee.

Hiking: Even while being low impact, routes with uneven ground and erupting roots or rocks can cause falls and be hazardous to the knee. So avoid hiking in rough terrain after knee replacement.

Skateboarding and Rollerblading: Holding a substantial risk of twisted knees and possible fall on hard surfaces these sports can lengthen the recovery process.

High-impact Sports or Aerobics: The negative impact of running with the risk of hitting other players in the process of damaging the knee is combined in some sports. One must avoid taking part in contact sports or sports that lead to a sudden twisting or jerking of the knee like soccer, football, rugby, basketball, skiing, hockey, gymnastics, etc.

Some great options to stay active after the knee replacement surgery are low-intensity sports like cycling, golf, and swimming.

Bottomline

Knee replacement surgery is a highly successful method of getting rid of knee pain which can hamper your life and normal activity.
