What Can You Do After Knee Replacement

Continuous Passive Motion Machines

Can I Jog After A Total Knee Replacement?

Some doctors prescribe continuous passive motion machines after surgery. A CPM machine slowly moves the affected leg, causing it to repeatedly straighten and bend, while the patient is lying on his or her back. A patient may use a CPM machine for up to 8 hours a day, in between sleeping and physical therapy.

Evidence suggests CPM machines help patients regain range of motion more quickly,1 which can facilitate a faster hospital discharge. Some patients are also prescribed CPM machines for temporary use at home after discharge.

Not all insurance companies cover CPM machines and, while they do help patients regain flexibility sooner, there is no definitive evidence that the CPM use affects risk of DVT, long-term knee range of motion, or knee function.2

Expected Range Of Motion

After knee replacement surgery, it is important to work with a physical therapist to achieve the maximal range of motion. Typically, the range of motion will progress quickly during the first three months and can continue to increase for up to two years following surgery.

Normal motion after knee replacement is defined as the ability to get within 5 degrees of a straight knee and the ability to bend the knee back to 90 degrees. Most knee replacements have movement ranging from 0 degrees to 110 degrees or more.

The optimal motion of the replaced knee can be achieved with a combination of stretches, exercises, and gradual resumption of normal activities. Some surgeons will recommend the use of a machine to bend the knee, called a CPM, .

Technical Details Of Total Knee Replacement

Total knee replacement surgery begins by performing a sterile preparation of the skin over the knee to prevent infection. This is followed by inflation of a tourniquet to prevent blood loss during the operation.

Next, a well-positioned skin incision–typically 6-7 in length though this varies with the patients size and the complexity of the knee problem–is made down the front of the knee and the knee joint is inspected.

Next, specialized alignment rods and cutting jigs are used to remove enough bone from the end of the femur , the top of the tibia , and the underside of the patella to allow placement of the joint replacement implants. Proper sizing and alignment of the implants, as well as balancing of the knee ligaments, all are critical for normal post-operative function and good pain relief. Again, these steps are complex and considerable experience in total knee replacement is required in order to make sure they are done reliably, case after case. Provisional implant components are placed without bone cement to make sure they fit well against the bones and are well aligned. At this time, good function–including full flexion , extension , and ligament balance–is verified.

Finally, the bone is cleaned using saline solution and the joint replacement components are cemented into place using polymethylmethacrylate bone cement. The surgical incision is closed using stitches and staples.

Helping Patients To Make Informed Decisions

We’re funding research to improve patient experience before, during and after knee replacement surgery. This includes a project based at the University of Sheffield which aims to help patients make informed decisions about their surgery. The research team will use the UK National Joint Registry dataset to develop and validate a personalised, web-based decision aid to help patients considering knee joint replacement to make informed choices about their treatment.

What Is Knee Replacement Surgery

Knee Replacement Exercises To Do After Surgery

Knee replacement surgery is a surgical technique to repair the knee joint. Plastic and metal prosthetic parts are attached to the bones in the knee joint. During the procedure, damaged cartilage and bone are cut away. Then an artificial joint is put in place.

This surgery might be required for someone with a severe knee injury or people who experience pain from chronic arthritis. A sports medicine doctor might recommend knee replacement surgery based on your knees strength, stability, and range of motion. A variety of surgical techniques and prostheses can be used, depending on your weight, age, knee size and shape, activity level, and overall health.

People Should Be Able To Kneel After Knee Replacement Why Arent They Research: It Has Nothing To Do With The Knee Replacement

Lets look at a January 2019 study in the Journal of Knee Surgery. It comes from the Department of Orthopaedic Surgery, The Johns Hopkins University.

Here are the summary points:

  • The ability to kneel is one of the many patient goals after total knee replacement.
  • Given the altered biomechanics of the knee after total knee replacement, the various implant designs, and multiple surgical approaches, there is a need to further understand the patients kneeling ability after total knee replacement.
  • In patients who do kneel after surgery, data show that increased range of motion promotes improved kneeling performance. Targeted interventions to encourage kneeling after total knee replacement, including preoperative education, have not shown an ability to increase the frequency with which patients kneel after total knee replacement.
  • Reasons for patient avoidance of kneeling are multifaceted and complex. There is no biomechanical or clinical evidence contraindicating kneeling after total knee replacement. There are insufficient data to recommend particular prosthetic designs or surgical approaches to maximize kneeling ability after surgery. Musculoskeletal health care providers should continue to promote kneeling to allow patients to achieve maximum clinical benefit after total knee replacement.

What Can You Expect After Knee Replacement Surgery

What to Expect After Knee Replacement Surgery. Typically a patients knee will be swollen, stiff, weak, and sore following surgery. This makes functional activities such as walking and standing up difficult to perform. The timeline for regaining strength and range of motion after knee replacement is variable.

Getting Into And Riding In A Car

When getting into a car:

  • Get into the car from street level, not from a curb or doorstep. Have the front seat moved back as far as possible.
  • Car seats shouldn’t be too low. Sit on a pillow if you need to. Before you get into a car, make sure you can slide easily on the seat material.
  • Turn around so the back of your knee is touching the seat and sit down. As you turn, have someone help lift your legs into the car.

When riding in a car:

  • Break up long car rides. Stop, get out, and walk around every 45 to 60 minutes.
  • Do some of the simple exercises, like ankle pumps, while riding in the car. This helps reduce the risks of blood clots.
  • Take pain medicines before your first ride home.

When getting out of the car:

  • Turn your body as someone helps you lift your legs out of the car.
  • Scoot and lean forward.
  • Standing on both legs, use your crutches or walker to help you stand up.

Ask your health care provider when you can drive. You may need to wait up to 4 weeks after surgery. DO NOT drive until your provider says it is OK.

How Common Is Knee Replacement Surgery

What Activities Can I Do After Total Hip or Knee Replacement?

The surgery is very common. Surgeons started doing it in the 1960s, with regular updates to techniques and implants along the way.

Almost 800,000 knee replacements currently get performed each year in the United States. The surgery is often done in older adults whose knees have worn down over time. But its also become popular in middle age, as people want to stay active.

What Are The Advantages Of Knee Replacement

Long-term, you may still feel some discomfort and have to limit high-impact activity to protect the replacement joint. But knee replacement can relieve a lot of the pain and help you move much better. More than 90% of people who have a total knee replacement still function well 15 years after surgery.

Dangers Of Doing Certain Exercises Too Soon

Performing movements or exercises that are too intense can increase the chances of loosening or fracturing the bones around the implant.

Pushing too much can also lead to increased pain and swelling around the knee, slowing down the rehabilitation process and making it more difficult to exercise.

Symptoms of pushing too hard during the recovery program might include:

  • increased pain
  • swelling of the knee or lower leg
  • warmth around your knee

If you experience any of these symptoms, its best to back off of the activity and ice your knee for 15 to 20 minutes.

If the symptom persists, call your healthcare provider.

Looking After Your Knee Replacement

Your new knee will continue to improve for as much as two years after your operation as the scar tissue heals and you exercise your muscles. You’ll need to look after yourself and pay attention to any of the following problems:

Stiffness Sometimes the knee can become very stiff in the weeks after the operation for no obvious reason. Try placing your foot on the first or second step of the stairs, hold on to the banister and lean into your knee. This should help to improve movement and flexibility in your knee. Its very important to continue with the exercises you were working on in the hospital.If the stiffness doesnt improve after about six weeks your surgeon may need to move or manipulate your knee. This will be done under anaesthetic.

Pain Pain caused by bruising from the operation is normal in the first two months, and you’ll probably still need to take painkillers at six weeks to help you sleep through the night. You may still have some pain for as long as six months. If you still have pain after this, speak to your physiotherapist or GP.

Infection You should speak to your GP or hospital if you notice any signs of infection, for example:

  • breakdown of the wound with oozing/pus or sores
  • increased pain
  • redness and the affected area feeling warmer than usual or smelling unpleasant.

You should also look after your feet see a doctor or podiatrist if you notice any problems such as ingrown toenails that could become infected.

If you dont get your range of motion to at least 90 degrees after surgery, youre not likely to be happy with the outcome. Knee replacements arent just something where you get the surgery done. Its a lot of work, Paull says.

What you can do: Understand what rehab will involve, and talk to your surgeon about the rehabilitation program offered at your center. Proper rehab can really determine how well the patient recovers and how well they return to their prior level of function, Biggart says.

About Total Knee Replacement

A Total Knee Replacement is a surgical procedure whereby the diseased knee joint is replaced with an artificial material. The procedure involves cutting away damaged bone and cartilage from your thighbone, shinbone and kneecap and replacing it with an artificial joint made of metal alloys, high-grade plastics and polymers.

Knee Replacement Recovery Exercises

Although you will be advised on specific exercises that you can do by your physical therapist, the exercises that you should focus on the most, particularly in the early recovery period, are exercises that work on range of motion, degree of bend in the knee as well as developing strength in the quadriceps muscles. As soon as you feel you are able to get onto a stationary or recumbent bike, you should do so. This is an excellent exercise as it is very low impact, but works on range of motion and strength, and the knee and can be aided by the contralateral side.

Working on range of motion and strength can be achieved by dangling your leg over the side of a chair or bed and extending the knee so that the leg is fully outstretched and holding it against gravity for several seconds before then allowing gravity to bend the knee again. This is a very simple exercise, but also very effective and can be done anywhere with relative ease and does not require any special equipment.

How Do I Determine If I Need A Knee Replacement

If youre considering knee replacement surgery, talk to an orthopedic surgeon. Orthopedic surgeons specialize in operations to fix joints and muscles.

Your orthopedic surgeon will:

  • Ask about your symptoms, including how severe they are and how long youve had them. The surgeon may also ask whether anything makes symptoms better or worse, or whether symptoms interfere with your daily life.
  • Take your medical history to learn about your overall health.
  • Examine you to check knee motion, strength and stability.
  • Order X-rays of your knee. The images can help the surgeon understand how much damage is in your knee. Advanced imaging is rarely helpful in the arthritic knee.

The orthopedic surgeon will then make a recommendation for surgery or another treatment option.

Early treatment of the stiff TKA includes physical therapy and manipulation under anesthesia . MUA performed within 3 months may have the greatest increase in ROM but notable improvement can occur up to 6 months after TKA. After six months, arthroscopic or open surgery is recommended for persistent stiffness.

Why Would I Need Surgery

Osteoarthritis is the main reason why people go for knee replacement surgery. The age-related condition is very common and occurs when cartilage — the cushion between the knee and the bone joints — breaks down.

Other reasons include:

  • Rheumatoid arthritis: Rheumatoid arthritis is when the bodyâs immune system attacks and destroys the lining of the knee.
  • Deformities: People with bowed legs or âknock-kneesâ often get surgery to restore the position of the knee.
  • Knee injuries: A broken bone or torn ligaments around the knee sometimes will result in arthritis that causes great pain and limits your movement.

Getting Back To Normal

It will be some weeks before you recover from your operation and start to feel the benefits of your new knee joint. Make sure you have no major commitments including long-haul air travel for the first six weeks after the operation.

Keeping up your exercises will make a big difference to your recovery time. Youll probably need painkillers as the exercise can be painful at first. Gradually youll be able to build up the exercises to strengthen your muscles so that you can move more easily.

Can Rehabilitation Be Done At Home

All patients are given a set of home exercises to do between supervised physical therapy sessions and the home exercises make up an important part of the recovery process. However, supervised therapy–which is best done in an outpatient physical therapy studio–is extremely helpful and those patients who are able to attend outpatient therapy are encouraged to do so.

For patients who are unable to attend outpatient physical therapy, home physical therapy is arranged.

Types Of Arthritis That Affect The Knee

Post Knee Replacement Surgery Care

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

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 .

They Rushed Into Surgery

There are times when getting stronger and exercising can help get rid of knee pain, but sometimes people jump into surgery when more conservative measures may have worked better for them, says Jasmine Marcus, a physical therapist with McCune and Murphy Physical Therapy.

What you can do: Marcus recommends exercising and building strength, enlisting the help of a physical therapist if necessary.

Even if you still end up needing surgery, getting stronger can help. Performing prehab exercises and getting the bodynot just the leg in questionas strong as possible tends to improve outcomes after surgery, says Tom Biggart, a physical therapist, athletic trainer, and strength and conditioning coach with EBM Fitness Solutions.

Recovery Is Different For Everyone

Generally, people are pretty far along by six weeks and mostly recovered by three months after surgery. Minor aches and pains may last for a while longer.

Your recovery time will vary depending on whether you have a partial or full knee replacement. You will need to walk with a cane for at least a couple of weeks. Return to work can vary, but generally expect at least a couple of weeks.

For the first four to six weeks after surgery, therapy will focus on improving your range of motion. Many people start with muscles that are atrophied, or weakened, especially if they were limiting their activities for a long time before surgery. For them, it may take longer to recover, making it important to continue an exercise program focused on building strength.
