Looking For Alternatives To Total Knee Replacements

How To Know If You Need A Total Knee Replacement

We’re also funding research which is investigating alternative approaches to total knee replacement. For example, total knee replacement is not recommended for many young people. This study aims to develop a new method called ToKa®, which uses images of the patient’s joint and specially designed software to design a patient specific implant that will be made via 3D printing. If successful, this technique could prevent osteoarthritis patients from needing total joint replacement.

What Are The Possible Risks And Complications Of Knee Replacement Surgery

Knee replacement surgery is generally considered safe and effective. However, complications can include:

  • infections
  • blood clots in the leg veins
  • implant problems
  • continued pain
  • injury to your nerves or blood vessels during surgery

If the knee becomes red or swollen, your pain gets worse or you become short of breath, go straight back to the hospital emergency department. These could be signs of a blood clot in your leg or your lungs.

Outlook For Knee Replacement

While some activities are off-limits after a knee replacement, you still have plenty of others to choose from. Unlimited walking, golf, light hiking, cycling, ballroom dancing, and swimming are all safe for most people with knee implants. By following your doctor’s guidelines, you can expect long-lasting results — about 85% of knee replacements will last 20 years.

This Common Procedure Can Help Reduce Pain And Restore Your Ability To Move Better But How Do You Know When Its Time For Surgery

Knee replacement surgery is one of the most successful procedures in all of medicine, according to the American Academy of Orthopaedic Surgery . Its also very common: Over 790,000 knee replacements are performed each year in the United States. A complete knee replacement more correctly, a resurfacing places metal pieces to recreate the surface of the joint, with a plastic separator in between and possibly a plastic resurfacing of the inside of the kneecap .

Although youll need a little help afterward, you should be able to begin walking again either the same day or the day after surgery. And the procedure is overwhelmingly successful: The AAOS estimates that 90% of modern total knee replacements are still working more than 15 years after surgery.

How do you know if you need a knee replacement in the first place? Deciding when its time is a personal decision between you and your doctor, but there are some factors that make you a more likely candidate for surgery.

Knee Osteoarthritis Symptoms Causes And Risk Factors

10 Things To Know About Knee Replacement Surgery

According to the National Institute on Aging, knee osteoarthritis is one of the leading causes of physical disability for older adults, affecting about 10 million adults around the United States. In a healthy knee joint, cartilage acts as a protective buffer between the bones, allowing the joint to glide smoothly during movement. Over time, however, this cushioning may slowly wear away, leaving the bones less protected, and even allowing them to come into direct contact with each other in severe cases. This condition is known as knee osteoarthritis.

There are many symptoms associated with osteoarthritis, which vary depending on the severity of the condition. Joint inflammation, stiffness, and a diminished range of motion are all common osteoarthritis symptoms. Arthritis knee pain may fluctuate throughout the day, and many individuals report more pronounced stiffness and swelling during the early morning hours, or after prolonged sitting or general inactivity. Knee arthritis symptoms may also worsen after extended physical activity involving the affected joint. In some instances, patients report instability and weakness during these activities. It is possible for damaged portions of the cartilage to break away from the healthy tissue and disrupt the natural glide of the knee joint, causing locking or popping sensations.

Who Gets Knee Replacement Surgery

You may consider knee replacement surgery if:

  • Arthritis in the knee or a knee injury has severely damaged the mating surfaces of the joint.
  • Pain and stiffness give you trouble doing everyday activities, such as walking up or down stairs or getting in and out of a car.
  • Swelling and inflammation dont go away with rest and medication.Your knee is deformed, such as looking swollen or not shaped normally.

Should You Have Both Knees Replaced At The Same Time

Many people with osteoarthritis have problems with both knees, but usually one knee is worse than the other. Most people have surgery on one knee at a time, though some patients want to have surgery on both knees at the same time. The plus side of this is that you only need one operation, but the downside is that its a harder, slower recovery.

There are strict criteria for having both knees operated on at the same time, including being in overall good health and being motivated to undergo a more difficult recovery.

Your Knee Has Become Deformed

If your arthritis is advanced, it can affect the way you walk, which can also lead to further problems elsewhere in your body.

As arthritis progresses, the knee may become bowed or knock-kneed, Heckmann says. If this type of deformity develops over time, a knee replacement may be indicated.

In addition, people with arthritis may also lose the ability to straighten their knee, according to Heckmann. If this occurs, you should seek an evaluation with an orthopaedic surgeon, as this loss of motion may be permanent, even after the knee has been replaced, he adds.

Everything You Ever Wanted To Know About Total Knee Replacement Surgery

Knee replacement implants are expected to function for at least 15 to 20 years in 85% to 90% of patients. However, the implants do not last forever.

After a period of 15 to 20 years, general wear and tear may loosen the implant. Depending on the patient, this may cause no symptoms, or it may cause any of the following:

  • pain
  • knee instability
  • infection

When these symptoms arise, orthopedic surgeons recommend having to replace the original implant. Infection, especially, requires a prompt revision surgery. Infection after knee replacement surgery is rare, but a knee replacement implant cannot defend itself from infection if bacteria are introduced to the body. Learn more about the at HSS.

As You Begin To Recover

The goal of the first 2 weeks of recovery is to manage pain, decrease swelling, heal the incision, restore normal walking, and initiate exercise. Following those 2 weeks, your physical therapist will tailor your range-of-motion exercises, progressive muscle-strengthening exercises, body awareness and balance training, functional training, and activity-specific training to address your specific goals and get you back to the activities you love!

Range-of-motion exercises. Swelling and pain can make you move your knee less. Your physical therapist can teach you safe and effective exercises to restore movement to your knee, so that you can perform your daily activities.

Strengthening exercises. Weakness of the muscles of the thigh and lower leg could make you need to still use a cane when walking, even after you no longer need a walker or crutches. Your physical therapist can determine which strengthening exercises are right for you.

Body awareness and balance training. Specialized training exercises help your muscles “learn” to respond to changes in your world, such as uneven sidewalks or rocky ground. When you are able to put your full weight on your knee without pain, your physical therapist may add agility exercises and activities using a balance board that challenge your balance and knee control. Your program will be based on the physical therapists examination of your knee, on your goals, and on your activity level and general health.

Ligament Retaining Or Sacrificing

The posterior cruciate ligament is important to the stability of the knee by preventing posterior subluxation of the tibia, reducing shear stress, increasing flexion and lever arm of the extensor mechanism by inducing femoral rollback upon flexion, and thus minimizing polyethylene abrasion through reducing stress applied to the articular surface. The PS implant uses a post that is built into the implant to accommodate for the loss of PCL. Proponents of retaining the PCL advise that it is difficult to balance a CR knee and un-natural physiologic loads may increase wear of the polyethylene. Multiple studies have demonstrated minimal to no difference between the two designs.

Signs Of Knee Replacement Failure

No one likes to hear the word failure when you are scheduled for surgery. Those of us who made the decision to have total knee replacement did so because we were looking forward to having a functional, pain-free knee.

The last thing we wanted were complications that needed additional medical care or further surgery.

Doctors are not perfect. When I was a youngster, I thought teachers, police and doctors could do no wrong. As I aged, I learned that everyone is human and can make a mistake. Even your surgeon.

There are other factors besides physician error that can cause complications after surgery. In the sections below, I will discuss some things that could go wrong during the knee replacement process.

Remember, there are several things that you can do prior to knee replacement surgery to improve the chances of a successful outcome. Building leg strength, stretching, exercising and weight management are a few pro-active steps you can do to increase the probability of success.

My experience, as well as my discussions with TKR veterans, leads me to believe that the vast majority of knee replacement surgeries have a positive outcome.

15 things you need to know about knee replacement

Urquhart: When all of the non-operative options listed above do not work, patients should consult with an orthopaedic surgeon to discuss partial or total knee replacement surgery.

The consult will usually include discussing symptoms, a few strength and ligament tests, X-rays and discussing the benefits and risks of surgery.

Knee Replacement Recovery Time And Recuperation

Total knee replacement surgery generally takes about 60 to 90 minutes, but you should expect to be in the operating room for over two hours. Rehabilitation will begin within 24 hours of surgery.

After your surgery, the nursing staff will position you in bed and help you turn until you are able to move on your own. You may have a pillow between your legs if ordered by your surgeon.

Very soon after surgery, a physical therapist will come to your room to teach you appropriate exercises and review your progress. Gentle exercises to improve your range of motion can help prevent circulation problems as well as strengthen your muscles.

Your rehabilitation program will begin as soon as you are medically stable and there are orders from your doctor to begin postoperative mobility. All patients begin rehabilitation within 24 hours of their surgery. Your motivation and participation in your physical therapy program is key to the success of your surgery and recovery. The physical therapist will assist you in the following activities:

  • sitting at bedside with your feet on the floor
  • transferring in and out of bed safely
  • walking with the aid of a device
  • climbing stairs with aid of a device

What Are Possible Side Effects Of The Surgery

Urquhart: All surgeries have a risk of complications. Less than 1% of healthy patients undergoing any type of surgery can experience a cardiovascular event, such as a heart attack or stroke. About 0.5% of knee replacement surgery patients develop an infection.

But an important side effect or outcome to talk about is this buyers remorse idea I brought up earlier. About 15 to 20% of patients that undergo total knee replacement surgery have buyers remorse because they still experience discomfort, clicking or a sensation of instability in their knee, making them regret having the procedure. That is exactly why we consider non-surgical options first and remind patients that they should not make the decision to have surgery without careful consideration.

Do You Have To Come To The Hospital For Total Knee Replacement Surgery

Urquhart: Knee replacements in healthy patients do not require a hospital stay. In fact, we now offer the surgery at the Brighton Center for Specialty Care, one of our outpatient specialty clinics.

Patients have the surgery performed in one of the operating rooms at the facility and then are moved into a recovery area where they are monitored and work with physical therapy to be safe to go home. The center has the ability and staffing to monitor patients overnight, if needed. Then the patient is able to finish their recovery at home.

What The Alternatives To Knee Replacement


A healthcare provider may recommend knee replacement surgery after other treatments for knee pain dont help anymore. These earlier options may include:

  • Exercise or physical therapy to strengthen the muscles around the joint which will provide stability.
  • Medications such as NSAIDs and cortisone shots.

Types Of Arthritis That Affect The Knee

Inflammatory arthritis

This broad category includes a wide variety of diagnoses including rheumatoid arthritis, lupus, gout and many others. It is important that patients with these conditions be followed by a qualified rheumatologist as there are a number of exciting new treatments that may decrease the symptoms and perhaps even slow the progression of knee joint damage.

Patients with inflammatory arthritis of the knee usually have joint damage in all three compartments and therefore are not good candidates for partial knee replacement. However, inflammatory arthritis patients who decide to have total knee replacement have an extremely high likelihood of success. These patients often experience total, or near-total, pain relief following a well-performed joint replacement.


Osteoarthritis is also called OA or degenerative joint disease. OA patients represent the large majority of arthritis sufferers. OA may affect multiple joints or it may be localized to the involved knee. Activity limitations due to pain are the hallmarks of this disease.

OA patients who have symptoms limited to one compartment of the knee sometimes are good candidates for minimally-invasive partial knee replacement .

What Kind Of Physical Therapist Do I Need

Although all physical therapists are prepared through education and experience to treat people who have a total knee replacement surgery, you may want to consider:

  • A physical therapist who is experienced in treating people with orthopedic, or musculoskeletal, problems
  • A physical therapist who is a board-certified clinical specialist or who has completed a residency or fellowship in orthopedic physical therapy, giving the physical therapist advanced knowledge, experience, and skills that may apply to your condition

You can find physical therapists who have these and other credentials by using Find a PT, the online tool built by the American Physical Therapy Association to help you search for physical therapists with specific clinical expertise in your geographic area.

General tips when you’re looking for a physical therapist:

  • Get recommendations from family and friends or from other health care providers.
  • When you contact a physical therapy clinic for an appointment, ask about the physical therapist’s experience in helping people with knee replacements.

During your first visit with the physical therapist, be prepared to describe your symptoms in as much detail as possible, and say what makes your symptoms worse.
