The deterioration of joints and knee pain can significantly impact the quality of your life, limiting your mobility and causing discomfort. If you have knee conditions that fail to respond to conservative treatments, getting a knee replacement surgery is a potential solution.
A knee replacement involves removing the damaged or worn-out parts of the knee joint and replacing them with prosthetic components, restoring function and alleviating pain. There are several types of knee replacement surgeries available, each tailored to the patient's unique needs and the extent of joint damage.
Knee replacement surgery procedure
Also known as knee arthroplasty, knee replacement surgery has a goal to restore normal knee function and relieve pain and discomfort. The procedure removes the knee joint’s damaged cartilage and bone and then replaces it with artificial components.
The surgeon carefully resurfaces the ends of the femur and tibia bones and positions the prosthetic components to mimic the natural joint's movement. There are many different techniques that can be utilized when performing this surgery, such as total knee replacement, partial knee replacement, and knee replacement revision.
Knee replacement surgery options
Depending on the severity of your knee, there’s more than one knee replacement surgery option available. There’s total knee replacement, partial knee replacement, and knee replacement revision. We highly recommend you consult with your doctor to find the best option for you.
Total knee replacement
Total knee replacement is the most common type of knee arthroplasty. It involves replacing all three compartments of the knee joint with artificial components.
The surgeon first removes the damaged cartilage and bone from the femur, tibia, and patella. Then, replaces them with metal and plastic implants. This comprehensive approach is usually recommended for patients with severe arthritis affecting the entire knee joint.
Partial knee replacement
Partial knee replacement, also known as unicompartmental knee replacement, is a less invasive option. It addresses only one knee joint compartment, leaving the healthy portions intact. This procedure is suitable for patients with localized arthritis damage, preserving more of the patient's natural bone and ligaments.
Knee replacement revision
Knee replacement revision is performed when a previous knee replacement has failed or worn out. This complex procedure involves removing the old implants and replacing them with new components. It's often more intricate due to the presence of scar tissue and altered bone structures.
How is a knee replacement performed?
During knee replacement surgery, the procedure usually involves several important steps. First, the patient either receives general anesthesia to put them to sleep or regional anesthesia to numb the lower body. Once the patient is comfortable, a skilled surgeon makes an incision over the knee, allowing access to the joint. Then, the surgeon removes the damaged bone and cartilage from the femur, tibia, and patella. After that, artificial implants, often made of metal and plastic, are placed precisely and securely onto the bone surfaces. Once the implants are in place, the incision is carefully closed up, and the surgical area is dressed and taken care of. On average, this type of surgery takes about 1 to 2 hours, and afterward, there's a period of time needed for recovery and rehabilitation.
Types of knee implants
Knee implants come in various materials and configurations, each with its own set of advantages and considerations. What may work for others may not necessarily work for you. That’s why different options are available, and your doctor will install the material that suits your condition.
Ceramic-on-plastic
Ceramic-on-plastic implants involve a ceramic femoral component interacting with a plastic tibial component. The material is very smooth and wear-resistant, which is why it’s a popular choice for younger and more active patients.
Ceramic-on-ceramic
Ceramic-on-ceramic implants involve both the femoral and tibial components being made of ceramic. This combination offers long-lasting durability, reduced wear, and minimal friction. As a result, doctors find this suitable for patients with a long life expectancy.
Metal-on-metal
Metal-on-metal implants involve metal components for both the femur and tibia. This option was once popular due to its durability, but concerns about metal ion release and potential adverse reactions have declined its use.
Metal-on-plastic
Metal-on-plastic implants involve a metal femoral component rubbing against a plastic tibial component. This combination offers good durability and low friction, enabling smooth joint movement.
Advantages of knee replacement surgery
There are many advantages to getting knee replacement surgery. One of the most notable benefits is the significant reduction in pain and improved mobility. This procedure can be life-changing to individuals who are dealing with chronic knee pain, as well as a restriction in movements because of arthritis or joint damage. The relief from pain allows patients to engage in daily activities with greater ease and even resume physical activities that were once impossible.
What to expect after knee replacement?
After knee replacement surgery, patients can expect some post-operative pain, which is managed through medications and pain relief techniques. As the recovery progresses, pain diminishes, and patients can experience increased mobility and improved joint function. Physical therapy plays a crucial role in this phase, helping patients regain strength and flexibility in the operated knee. Most patients can return home within a few days after surgery, although full recovery may take several months.
Recovering from a knee replacement
Recovery from knee replacement surgery involves a balance between movement and rest. Physical therapy exercises are designed to gradually increase the range of motion and strengthen the surrounding muscles. It’s expected for patients to follow their surgeon's orders,
do necessary exercises, maintain a healthy diet, and avoid activities that could strain the healing knee.
Frequently asked questions
What are the different types of knee replacement surgery?
There are three primary types of knee replacement surgery: total knee replacement, partial knee replacement, and knee replacement revision. Each targets different degrees of joint damage and has specific criteria for patient selection.
What to expect one year after total knee replacement?
Most patients experience significant pain relief and improved mobility one year after total knee replacement. However, the extent of recovery can vary based on individual factors and adherence to rehabilitation protocols.
What is a partial knee replacement?
Partial knee replacement involves replacing only the damaged part of the knee joint, leaving the healthy portions intact. It's suitable for patients with localized arthritis damage.
What to do if you fall after knee replacement?
It’s important to contact your healthcare provider immediately if you fall after your knee replacement surgery. This is because your healing process can be impacted, and your surgeon will evaluate your condition to make sure there's no damage to the surgical site.
How much is a knee replacement?
The cost of knee replacement surgery can vary based on factors such as the type of procedure, the hospital's location, and insurance coverage. It's advisable to consult with your healthcare provider and insurance company to get an accurate estimate.
How is a knee replacement done?
A knee replacement involves removing damaged bone and cartilage and replacing them with artificial components made of metal, plastic or other materials. The implants mimic the natural joint's movement, easing discomfort and regaining mobility.
How long does a total knee replacement take?
The duration of a total knee replacement surgery typically ranges from 1 to 2 hours. However, the overall time spent in the hospital and the recovery period afterward can extend to several weeks or months.
