What is a Knee Replacement Revision?

Hundreds of thousands of Americans have total knee replacement surgery each year to treat severe knee arthritis that no longer responds to conservative treatments. Conservative treatments are those such as medications, physical therapy, or injections. In this surgery, the damaged joint surfaces of the knee are replaced with artificial metal and plastic implants. These knee implants may last individuals 20 or more years. For some people, their knee implants will last the rest of their lives. However, some knee replacements do not last as long as patients and their providers hope or wear out over time.

“I think every knee replacement surgeon hopes that the knee replacement they do for each patient is the last knee surgery for that individual. But sometimes knee replacements wear out over time or may not function as well as we hoped,” said Summit hip and knee surgeon and total joint replacement specialist Brandon Kelly, M.D.

What is a knee replacement revision?

A knee replacement revision is a surgery to replace one or multiple knee replacement parts with new ones. The specifics of each revision surgery depend on how and where the original implant is failing. Other factors include the individual patient’s age, health, activity level, and other factors.

The need for a knee replacement revision surgery is an individualized decision made between the patient and the surgeon. It is typically recommended when there is a problem with the current knee replacement implants or if the knee is not meeting the patient’s quality of life goals. The decision for knee replacement revision is individualized to each patient’s medical and social factors. Sometimes, surgical intervention may not align with every patient’s goals of care.

“Knee replacement revision is usually a big decision for patients and surgeons. I like to educate my patients on what’s going well and what’s not going well with their current knee replacements. Then we discuss what may or may not be improved with revision knee replacement surgery before proceeding with surgery. I like to understand my patients’ goals to ensure I can meet them before proceeding with surgical intervention,” Dr. Kelly noted.

What else is important to know about knee revision surgery?

Revision knee replacement surgery is typically a more complex, longer, and technically challenging surgery than total knee replacement. That’s why it’s important to choose your knee revision specialist carefully. There are many factors that contribute to postoperative recovery, but recovery time after revision knee replacement surgery in most circumstances is similar to a total knee replacement surgery.

As with a first-time knee replacement, preoperative and postoperative physical therapy is vital to help condition and strengthen the lower extremities.

How Long Does it Take to Recover from Total Knee Replacement Surgery?

in ,

Article featured on Arkansas Surgical Hospital

If your doctor has suggested total knee replacement surgery, it’s crucial to know what to expect after the procedure. Recovery from a total knee replacement surgery takes about three months and depends on how well you follow your surgeon’s instructions. Understanding the timeline will help you prepare for the downtime you’ll need while your knee takes time to heal and rebuild strength.

Understanding Total Knee Replacement Surgery

Knee replacement surgery is usually suggested when you experience severe, unrelenting pain that hasn’t been alleviated by other means. If there is loss of motion, a lot of grinding in the joint, or misalignment of the knee, a knee replacement can help.

What to Expect After Total Knee Replacement Surgery

Recovering from a knee replacement is a lengthy but worthwhile process. Here’s what to expect when you recover from your knee surgery at Arkansas Surgical Hospital.

The Day of Surgery

After your knee replacement is complete, you’ll be taken to the post-anesthesia care unit, where a nurse will carefully monitor your vital signs and incision. When your pulse, blood pressure, and breathing rate are normal, you’ll be transferred to your private suite in our patient care unit. In most cases, you’ll stay overnight. You’ll be given pain medication to keep you comfortable after your surgery.

Postoperative Care

You will meet with a physical therapist on the day of or the day after your total knee replacement. Your therapist will develop an exercise regimen to help you with mobility, which will start as soon as possible after surgery to prevent stiffening of the knee joint.

While you’re in the hospital, your physical therapist will take you through various exercises designed to strengthen and stabilize the knee. By the time you leave the hospital, you should be walking independently with an assisted device. Most patients discharge home from the hospital after 1-2 nights. Your surgeon will decide which is appropriate for you.

The First Six Weeks

Before you return home, make sure you have safety features installed. These may include a shower seat in the tub or shower, grab bars where needed, and other mobility aids recommended by your surgeon or physical therapist.

During the first six weeks at home following a total knee replacement surgery, the focus is on healing. You may take over-the-counter medications for pain, which your doctor can recommend.

Eat lots of iron-rich foods to promote healing and keep your strength up. At the six-week point after your surgery, you should be able to stand, sit, walk, and use the stairs unaided.

Returning to Work & Activities

Most patients can return to work after six to eight weeks. If your job involves manual labor or long stretches of time spent walking and standing, it may take you longer to return to full-time work. Your doctor can advise you on when you’re ready. It’s essential to pace yourself and not put too much stress on your knee joint before it’s strong enough to handle the load.

Exercise is vital for proper recovery from total knee replacement surgery. During the first several weeks after your procedure, walking and gentle exercises may be appropriate in addition to your physical therapy. Sports, jogging, and other high-impact activities need to be postponed until about two to three months after your surgery to give your joint time to heal and strengthen. Avoid lifting anything over 40 pounds during the first three months after your total knee replacement surgery.

Getting Back to Normal

Your body and your knee joint will continue to gain strength for several months after your surgery. There shouldn’t be any pain after the first four months. If you continue to feel pain, be sure to talk to your surgeon.

If you’ve participated in activities that are hard on your knees in the past, talk to your doctor about how to return to jogging, skiing, and other activities while protecting your new knee implant. There may be some activities that aren’t advisable.

Most patients fully recover within six months to a year of total knee replacement surgery. While this may seem like a long time, the knee replacement itself can last as long as 15-20 years, giving you many years of comfort and mobility.

Helpful Tips for the First Week After a Total Knee Replacement Surgery

in

Article featured on Orthogate

The first knee replacement surgery took place in 1968 and since that time it has become more common with an estimated 600,000 total knee replacements (TKA’s) occurring annually in the United States. It is one of the most successful operations in all of medicine thanks to advances in the materials and surgical techniques used. These improvements have resulted in shorter hospital stays; however, this means that more responsibility is placed on the patient in managing their own recovery. The toughest period can be the first week after surgery so we thought it helpful to provide the following tips to help you make it through.

Keep the Joint Moving

This is arguably the single most important piece of advice to remember. Maintaining continual, mild movement of the joint is critical for several reasons. First, and this may sound counterintuitive, the movement will help to improve pain. Normally we may think that we need to rest joints and muscles to help relieve pain, but recently repaired joints will actually hurt less with motion. The gentle movement also serves to circulate blood and prevent clots and reduces swelling. Just keep this in mind – “The more you move, the faster your recovery will be.”

Focus on Knee Extension Range of Motion First

Knee extension also called the knee straight, is the most crucial motion that you need to focus on during your post-surgery recovery. After a total knee replacement, your leg will be prone to remain in a bent state and therefore resistant to being straightened out. However, investing the time into knee extension/straightening will be essential to building and maintaining knee stability, decreasing stress on the supportive ligaments around your knee, and to ensure proper functionality of the quad muscle.

Manage Swelling

While some swelling can actually be a good sign during recovery, too much swelling can increase pain and knee stiffness and lead to a decrease in range of motion. Therefore, knowing how to manage your swelling will be of the utmost importance. Just remember the acronym M.I.C.E. – that stands for Movement Ice Compression and Elevation. Your doctor will likely prescribe medications that will help in controlling inflammation so be sure to take them as directed in order to keep your swelling in check. You can also keep swelling at bay by applying ice and pressure (compression bandage) to the knee when you are resting it. Additionally, elevating the knee when you are resting can help temporarily reduce blood flow to the joint and thereby help to decrease swelling.

Get the Muscles Working

Surgery essentially shuts muscles “off” and it is your job during your recovery period to turn them back “on” and get them to working again. Don’t worry so much about building strength, focus instead on continual movement. You should bend, straighten, and squeeze the muscles at least once every waking hour. This will help them gain more function and gradually increase strength.

Don’t Ditch the Walker too Early

Everybody wants to ditch the walker early on because it reminds them of their own mortality. However, we highly encourage you to keep your walker at least until you are no longer limping. If you get rid of the walker before your body is ready, you could very well end up walking with a bent knee that will lead to scar tissue formation, muscle contractures, and damage to other joints nearby. So stick it out with the walker or a cane for a little while longer than you’d like and you’ll be rewarded by having fewer mishaps down the road.

Conclusion

The first week after a total knee replacement can be the toughest time period of the entire recovery process. However, if you implement the strategies we’ve outlined above you will be better equipped to handle whatever challenges you encounter and you will be well on your way to quickly regaining your knee function and quality of life.

Partial and Total Knee Replacement: How are they different?

in ,

From Noyes Knee Institute

Strong, healthy knees are important for your mobility. Unfortunately, the knee joint is easily injured and is susceptible to damage from arthritis. Any damage or injury to the knee is painful and may limit your daily activities. Depending on which part of your knee is damaged, you may have the option of either a total or partial knee replacement.

Learn more about the difference between partial and total knee replacement to decide which is right for you.

Parts of the Knee

The knee joint consists of four bones: the femur, tibia, fibula, and patella. Four ligaments — two collateral and two cruciate — stabilize the connection of the bones while allowing movement. Menisci, or cartilage, minimizes the trauma of the femur and tibia sliding across each other, and small sacs of fluid between bones allow for smooth movement.

The knee is also divided into three distinct compartments: The medial compartment is the section of knee on the inside of the leg, the lateral compartment is on the outside of the leg, and the patellofemoral compartment is the area directly under the kneecap. A partial knee replacement is done when only one of these compartments is damaged.

Total Knee Replacement

A total knee replacement involves resurfacing the ends of the tibia and femur to remove all the damaged tissue. The damage could be deteriorated bone, cracked bone, or calcified bone as well as the damaged cartilage. Once the bad tissue is removed, metal caps are placed over the bones to recreate their original shape and size. These caps may snap on snugly or be glued in place.

With the bones recreated, the doctor determines whether the kneecap has been damaged or not. If there is damage, the underside will be cleaned, and then a plastic disc will be fit into place. Finally, plastic pacers are placed between all parts that may rub or slide against each other during movement.

Either or both of the cruciate ligaments of the knee may be removed during a total knee replacement if they are damaged. The collateral ligaments are not removed. When a cruciate ligament is taken out, the metal caps over the bones have a ridge or locking mechanism to ensure your bones do not move too far or slip out of place.

Partial Knee Replacement

A partial knee replacement requires the same resurfacing and metal caps but involves either the medial or lateral compartment. If both compartments have damaged tissue, or if the problem is within the patellofemoral compartment, a different treatment is needed.

If your knee is unstable and the bones slip to the side, forward, or backward, partial knee replacement is not an option. In addition, the anterior cruciate ligament must not be damaged for this procedure to work. No ligament is removed during a partial knee replacement.

When only one compartment needs repaired, you may consider a partial knee replacement. If your doctor deems you a good candidate for this procedure you will experience a few benefits over a total knee replacement. One of the most important benefit is that your knee will still function the way it always has because less of the joint is removed and replaced.

With a partial replacement, you may require more surgery and a total replacement in the future. One reason for this is that a partial replacement does not last as long as a total replacement. The other reason is that the remaining natural parts of the joint may become damaged as you age and require replacement too.

Who Needs Knee Replacement Surgery?

You and your doctor may consider knee replacement surgery if you have a stiff, painful knee that makes it difficult to perform even the simplest of activities, and other treatments are no longer working. Historically, this surgery has generally been reserved for people over age 50 who have severe osteoarthritis but with advances in technology, adults are more frequently opting for earlier surgeries to optimize their quality of life.
