To 2 Weeks After Surgery
The goals of the first one to two;weeks following surgery are to improve walking mechanics and stability, ensure that range of motion is from full extension to 90 degree of bending, and manage symptoms of pain and swelling. Early efforts to strengthen the knee can begin, but the focus should be on motion and pain control.
During the;first few weeks, it is important to pay attention to specific instructions from your surgeon. These may include instructions to ensure healing of the incision. Some people may need sutures or staples removed from their incision. You may have specific bandage requirements and recommendations about when you can get the incision wet.
Knee Replacement Range Of Motion
Knee swelling will limit knee flexibility, but there is also healing and scarring of tissues to consider that will prevent a knee from bending and straightening. ;Patients need to slowly improve their flexibility so their knee does not heal stiff, but at the same time not push too much that they are aggravating the recovery and causing more swelling.
The normal knee range of motion is 0 degrees of knee extension to 135 degrees of knee flexion . It is not unusual for someone to have 5-10 degrees of hyperextension and knee flexion varies anywhere from 120-150 degrees.
The expected range of motion after knee replacement is 0 degrees of knee extension to at least 115 degrees of flexion or greater, but this can take several weeks or months to achieve. Starting out, the goal is to get the knee to bend to 90 degrees within the first week and then improve 5 to 10 degrees each week after that until full flexion is reached. Again, this timeline is variable from patient to patient.
It is important to achieve full knee extension for walking to feel more natural and have less knee pain. If you dont achieve full extension, it will feel like youre walking with 1 leg shorter than the other.
Why Must I Take Antibiotics For Dental Work Or Other Surgical Procedures
Taking antibiotics is a precaution to help ensure that your new artificial joint does not become infected. Additional surgeries or dental work increases the chances of infection. No matter where the infection starts, if it spreads to your new knee, the results could be very serious. When artificial joints become infected, they must be removed surgically and then replaced. Please let your dentist or physician know that youve had joint replacement surgery. This is important no matter how small or straightforward the procedure.

How Long Does It Take To Recover From Knee Surgery
The timeline for recovering varies from patient to patient, but typically the rehabilitation process takes 10-12 weeks of therapy to reach goals of achieving range of motion, strength, and performing functional activities such as standing from sitting, walking, and climbing up/down stairs independently without difficulty or pain.
How Long Use Cpm After Knee Replacement

CPM machine, as the name continuous passive motion machine suggests, is essentially used to partake a limb or joint which has undergone surgery to stay in motion to increase the movement of that part of the body.
It does not cause any discomfort to the patient as the machine is attached to only the part which has undergone surgery and the patient can relax while the machine puts the limb through a various range of motions.
It can prove to be helpful for some, but not to all people. For those people whom the CPR machine could prove helpful, it can reduce the pain in the knee surgery, reduce the period of stay in the hospital, and increase the range of movements in the joint.
It is suggested that a person who has had knee replacement surgery, should wear the CPM machine for at least 3 weeks as it can help a lot in regaining movement of the joint without causing any major pain.
CPM machine has also proved to reduce the chances of swelling after the surgery, which otherwise could be very painful. It also helps in reducing the growth of scar tissues, which are not as flexible and could break after a short span of the muscle moving, hence, the CPM machine increases the growth of normal tissues which are flexible and can carry movement.
The CPM machine is recommended to be used on the bed as in any other place, there is a risk of it falling and breaking.

Other Forms Of Treatment
Without replacement surgery, a severely osteoarthritic knee joint may continue to deteriorate until it is impossible to go about your normal daily activities, such as standing up, walking or getting up from a seated position. Other forms of treatment include:
- The use of walking aids, such as frames or walking sticks
- Non-steroidal anti-inflammatory drugs
- Corticosteroid injections
- Other surgery, such as osteotomy an operation in which diseased bone is cut away in an attempt to properly align the malformed joint.
How Soon Will I Be Up And About
The staff will help you to get up and walk about as quickly as possible. If you’ve had keyhole surgery or are on an enhanced recovery programme, you may be able to walk on the same day as your operation. Generally, you’ll be helped to stand within 12 to 24 hours after your operation.
Walking with a frame or crutches is encouraged. Most people are able to walk independently with sticks after about a week.
During your stay in hospital, a physiotherapist will teach you exercises to help strengthen your knee. You can usually begin these the day after your operation. It’s important to follow the physiotherapist’s advice to avoid complications or dislocation of your new joint.
It’s normal to have initial discomfort while walking and exercising, and your legs and feet may be swollen.
You may be put on a passive motion machine to restore movement in your knee and leg. This support will slowly move your knee while you are in bed. It helps to decrease swelling by keeping your leg raised and helps improve your circulation.

How Long Will It Be Before I Feel Normal
You should be able to stop using your crutches or walking frame and resume normal leisure activities 6 weeks after surgery. However, it may take up to 3 months for pain and swelling to settle down. It can take up to a year for any leg swelling to disappear.
Your new knee will continue to recover for up to 2 years after your operation. During this time, scar tissue will heal and muscles can be restored by exercise.
Even after you have recovered, it’s best to avoid extreme movements or sports where there’s a risk of falling, such as skiing or mountain biking. Your doctor or a physiotherapist can advise you.
Exact Answer: Six To Eight Weeks
Deep Infection after Total Joint Replacement can be a significant, severe, and expensive consequence, needing a longer hospital stay, several surgical procedures, and long-term antibiotic usage in certain circumstances.
Bacteria that typically reside in the mouth or oral cavity are considered to be responsible for a tiny percentage of such;infections. It is widely understood that oral germs enter the circulation during dental treatment or even aggressive tooth cleaning/flossing. These newly circulating bacteria can lodge themselves on the edge of a joint replacement implant, where they cling tightly to the metal and proliferate, potentially leading to an infection that is difficult for the body to remove.;

Knee Replacement Recovery Tips
During your initial knee replacement recovery stages, make sure you get plenty of rest and fuel yourself with healthy foods and water.
Patek says, Your body is working hard to heal, and this, along with your physical therapy exercises, should be your primary focus during the initial recovery phase.
Before your surgery, you can help set yourself up for success by completing these knee injury prevention measures:
- Remove throw rugs and other tripping hazards around your home.
- Secure electrical cords to also prevent tripping.
- Make clear, wide paths to frequently traveled areas of your home; aim to make them wide enough for a walker.
- Talk with family and friends to help with meals during your first few days at home.
- Arrange for transportation to and from physical therapy and doctor check-ups as you will be unable to drive until your surgeon clears you.
- Determine a comfortable, accessible sleeping situation, preferably on the first level of your home.
- Set up a couch or chair with positions to appropriately elevate your knee above your heart.
- Place a small stool or shower chair in the shower to avoid slipping.
A return to regular physical activities post total knee replacement is usually encouraged. Whatever you enjoywalking, golfing, bowling, swimming, dancing, or even tennisshould eventually be comfortable on your new knee. Remember that your body was made to move, so listen to yourphysical therapists instructions and do what feels good to you.

Similar Conditions That Affect The Knee
Meniscus tear
Sometimes patients with knee pain don’t have arthritis at all. Each knee has two rings of cartilage called “menisci” . The menisci work similarly to shock absorbers in a car.
Menisci may be torn acutely in a fall or as the result of other trauma or they may develop degenerative tears from wear-and-tear over many years. Patients with meniscus tears experience pain along the inside or outside of the knee. Sometimes the pain is worse with deep squatting or twisting. Popping and locking of the knee are also occasional symptoms of meniscus tears.
Since some of these symptoms may be present with arthritis and the treatment of arthritis is different from that of meniscus tears, it is important to make the correct diagnosis. A good orthopedic surgeon can distinguish the two conditions by taking a thorough history, performing a careful physical examination, and by obtaining imaging tests. X-rays and Magnetic Resonance Imaging scans may be helpful in distinguishing these two conditions.
Knee Joint Infections
Also called infectious arthritis or septic arthritis, a joint infection is a severe problem that requires emergent medical attention. If not treated promptly knee infections can cause rapid destruction of the joint. In the worst cases they can become life-threatening.Symptoms of a knee joint infection include:
- severe pain
- fevers and
Again, a joint infection is a serious condition that requires immediate medical attention.

What Happens If You Dont Do Physical Therapy After Knee Surgery
Why you should commit to physical therapy after knee surgery
Its important to get moving and functioning as soon after the procedure; otherwise, the following can occur: Decreased blood flow to the area can negatively affect healing at the surgical site. Muscles can weaken and atrophy if they go too long without use.
Walking After Knee Surgery
As previously mentioned, walking after knee surgery will likely begin the day of or day after surgery in the hospital with a walker or cane. The amount of weight put on the surgical leg is usually as much as tolerated, so using the walker and taking smaller steps can help offload a painful knee. The goal of walking early is to prevent muscles from weakening and to get the knee moving in a normal gait pattern again.
Patients that are hesitant to walk or use the walker as a crutch for too long can also delay the recovery process. This goes back to the as tolerated concept. If you can tolerate walking without a walker, then walking starts with short bouts until longer distances are comfortable.

How Long Should You Stay Awake
The staff mostly support you to get up and walk as fast as you can. But if you have had a keyhole surgery or an enhanced recovery programme then it can be difficult walking on the same as the operation. Mostly, you can stand in 12 to 24 hours after your surgery.;
The doctors/nurses would give a frame or a crutch to help you walk. Most people are able to walk easily using sticks after about a week.;
While you are staying at the hospital, the physiotherapist is most likely to teach you some exercise to improve and strengthen the knee. Try to learn them as they begin instantly after the surgery. Once you follow the physiotherapist advice to avoid potential risk or dislocation in your new joints, you are good to go. ;
Its perfectly common to experience initial discomfort and pain while walking and exercising. Your legs and feet may get swollen so dont try to intensify but continue to exercise regularly.;
A passive motion machine is used on patients to restore movement in the knee and the leg. It helps to support your legs to slowly move the knees while you are in your bed. It also helps to reduce swelling by raising the legs high and improving the blood circulation.;
Why It Is Done
Doctors recommend joint replacement surgery when knee pain and loss of function become severe and when medicines and other treatments no longer relieve pain. Your doctor will use X-rays to look at the bones and cartilage in your knee to see if they are damaged. This helps the doctor make sure that the pain isn’t coming from somewhere else.
Doctors may not recommend knee replacement for people who:
- Have poor general health and may not tolerate anesthesia and surgery well.
- Have an active infection or are at risk for infection.
- Have osteoporosis .
- Have severe weakness of the quadriceps muscles at the front of the thigh.
- Have a knee that appears to bend backward when the knee is fully extended , if this condition is due to muscle weakness or paralysis.
- Are severely overweight. Replacement joints may be more likely to fail in people who are very overweight.
Some doctors will recommend other types of surgery if possible for younger people and especially for those who do strenuous work. A younger or more active person is more likely than an older or less active person to have an artificial knee joint wear out. People who are very overweight are also more likely to have an artificial knee joint wear out from the extra stress on the joint.

My First Night In The Hospital
In my earlier article I left off after having dinner my first night in the hospital. After dinner, my day shift nurse brought in the night shift team and introduced them.
I had a new nurse that had two assistants and a nursing supervisor for the floor. They put the new team names on my whiteboard in front of my bed so I could remember and call them by name.
My new nurse informed me she was a traveling nurse and therefore she had limited knowledge of this particular hospital.; She said she would do her best to meet my needs. She also told me that I was one of 5 patients assigned to her during this twelve-hour shift thats no easy task!;
She went over my health information on the computer, scanned my wristband and made sure all the information she had received from the day shift was correct and up to date. When it was time for my pain medication she first asked me to tell her my name and date of birth .
She asked me to rate my current pain level on a scale of one to ten (I was constantly asked about my pain level on a 0-10 scale and the staff tried their best to keep me below 5. She recorded my response, scanned my wristband then gave me the Percocet pill which I took orally.
The questions became a habit before receiving medication.; They were always double-checking to avoid mistakes.
She returned in a few minutes with another pill that I was to begin taking regularly to help with bowel movements.; Apparently, the pain medication has a tendency to back you up.
