What Are The Differences

When a person opts for a knee replacement, a surgeon removes or resurfaces damaged bone and cartilage and then replaces the knee with prosthetic components. In a total knee replacement, the entire joint is replaced with a prosthetic one. In a partial replacement, only a portion of the knee is replaced. This might be a good option for patients whose disease or deterioration of the knee has not progressed into multiple compartments.

Knee Replacement Options

Suppose youve developed arthritis and are experiencing weakness, pain, and limited movement in your knee. If these symptoms last, your physician may recommend knee replacement surgery, also called arthroplasty.

This procedure involves removing damaged or diseased surfaces and replacing them with metal or plastic parts. It often improves the quality of life for patients and eliminates their pain. Recovery time and post-operative mobility, however, depend on the kind of replacement you receivepartial or total.

Both replacement procedures remove about a fourth of an inch of the worn cartilage and bone from the end of the femur and tibia . Then, a surgeon resurfaces with metal and plastic caps.

Difference Between Total And Partial Knee Replacement

The knee has three compartmentsthe medial compartment , the lateral compartment and the patellofemoral compartment . In some knee osteoarthritis patients, only one compartment of the knee is affectedusually the medial compartment. The lateral compartment can be affected, but it is less common.

A partial or unicondylar knee replacement, as its name suggests, replaces only the affected compartment of the knee. On the other hand, a total knee replacement involves the replacement of all three compartments of the knee.

While just one compartment is replaced during partial knee replacement, anterior and posterior cruciate ligaments are preserved. The ligaments are removed in a total knee replacement. Suffice it to say, with a partial knee replacement, more of your own body structure remains intact.

Advantages Of Partial Replacements

Right at the top of the list is a smaller incision. Since this method removes less bone tissue and cartilage AND its contained to one area, your surgeon will only need about half the incision area compared to total replacement. Less trauma both internally and externally equates to a much faster recovery.

Speaking of recovery, that tends to be slashed in half as well . Total knee replacement usually requires you stay in the hospital about 5 days and therapy takes another 4-6 weeks before you start feeling stable and relatively pain-free. With partial replacement, most patients are discharged 1-2 days after surgery, some even the same day. After about 2-3 weeks of therapy, most patients have healed up quite well and can resume most of their daily activities.

Finally, with less cutting and trauma to the actual knee, there are much fewer complications associated with partial. In general, theres a much smaller risk of infection and bleeding is kept to a minimum.

Typically knee replacement surgery is done for chronic osteoarthritis of the knee joint that has not been successfully treated with non-operative means like medication, bracing, injections, and physical therapy, he explains. Arthritis is an inherited trait, so for most people, its just a genetic wearing out of the joint.

    Time to move on Many of these non-operative treatments can be good for mild to moderate arthritis, and you can go for years without joint replacement surgery, Dr. DeMaagd says. But after a while, those measures just dont work. You have to move on to something else. Thats when patients typically contact OAM. If the knee pain and stiffness are affecting a patients quality of life or getting in the way of normal daily activity, the patient is probably a good candidate for a knee replacement, says Dr. DeMaagd.

    Knee replacement surgeries are safe and effectively manage the pain and disability caused by osteoarthritis. During knee replacement surgery, the ends of the diseased joint are replaced with prosthetic metal and plastic parts.

    While in total knee replacement all the compartments of the knee joint are usually replaced, a partial knee replacement only involves the replacement of a single knee compartment.

    The knee joint is divided into three compartments or spaces. The joint is formed by the lower end of the thigh bone, the upper part of the shinbone, and the undersurface of the kneecap.

    The inner side of the knee is called the medial compartment, and similarly, the outer side of the knee forms the lateral compartment. In front of the knee, the joint formed by the kneecap and the thigh bone forms the patellofemoral compartment.

    The bones forming the knee joint are covered with a glistening white tough tissue known as articular cartilage. The articular cartilage helps in the smooth gliding of the joint in motion. Various ligaments, meniscus, and muscles provide additional stability to the knee joint.

    Patients with knee arthritis may complain of pain, stiffness, or deformity. A knee replacement surgery is only offered to the patients when all other nonsurgical treatments have been tried. Nonsurgical treatments include physical therapy, cortisone injections, and pain medications, etc.

    About Knee Replacement Surgery

    A total knee replacement, knee arthroplasty, is really a knee resurfacing because only the surface of the bones is replaced. The damaged cartilage is removed with a small amount of underlying bone and replaced with metal components that recreate the surface of the joint. The under-surface of the patella, kneecap, is cut and resurfaced with a plastic button. A medical-grade plastic spacer is inserted between the metal components to create a smooth gliding surface. Knee replacement surgery was first performed in 1968. Since then, improvements in surgical materials and techniques have greatly increased its effectiveness. According to the Agency for Healthcare Research and Quality, more than 600,000 knee replacements are performed each year in the United States.

    What Is The Difference Between A Partial And Total Knee Replacement

    Total knee replacement is one of the common solutions for knee osteoarthritis, which involves the deterioration of articular cartilage. One of the primary factors in differentiating if a candidate should receive either a partial or total knee replacement is where the pain is located.

    If the knee pain is isolated to either the inside portion or outside portion of the knee, then the patient might be a candidate for a partial or unicompartmental knee replacement. However, if severe knee pain exists throughout the whole knee, or towards the front of the knee underneath the kneecap, then a total knee replacement may be the necessary solution for the patient.

    When Do You Need Partial Vs Total Knee Replacement

    Christopher B. Lynch

    Painful arthritis of the knee affects up to 10% of the general United States population over 65 years of age. As a result, data estimates that approximately 350,000 total knee replacements are performed each year in the United States. In the past, knee replacement was typically reserved for the elderly, more sedentary patients with significant disease throughout the entire knee. Increasing demand from younger, more active patients with variable amounts of knee disease has prompted advances in knee replacement designs and techniques and has led to expanded use of total and partial knee replacement. In patients with severe arthritic disease affecting only one compartment, it may not be necessary or wise to replace all three joint surfaces.

    In joints that rely on more than one cartilage interface, like the knee, arthritis may not significantly affect all of these opposing cartilage surfaces. Therefore, it is not always necessary to replace the minimally diseased surfaces nor is it necessary to sacrifice, as extensively, essential stabilizing ligaments, muscles or tendons. Knee replacement replace individual diseased compartments while leaving healthy joint surfaces and normal knee stabilizing ligaments intact.

    Three Types Of Implants For Knee Replacement

    A knee replacement is a procedure that replaces a damaged or diseased knee joint with an artificial joint. A knee replacement implant can be fixed, hinge-type, or rotate-type. Implants that are fixed-bearing are the most common, and are ideal for patients who are not overweight but are not active. The implants are typically of the highest quality and are surgically placed on the bone. A hinge-type implant is inserted through a small incision in the knee and can be adjusted for each individual based on their specific requirements. Patients who are active and have a high level of health are more likely to prefer them over fixed-bearing implants. implants that rotate as the knee moves outside the knee joint The implants are less common and less durable than the others, making them less common.
