How Is Knee Replacement Performed
Knee replacements are performed in hospitals and orthopedic surgery centers. A knee replacement can either be an open or minimally invasive procedure. Open knee replacement surgery requires an 8- to 10-inch incision over your knee to expose the whole joint and place the knee implant. With minimally invasive knee replacement , your surgeon makes a 4- to 6-inch incision. In general, partial knee replacements typically require a smaller incision than total knee replacements.
Open procedures are the traditional method of performing a knee replacement. However, minimally invasive surgery, as compared to an open procedure, generally entails a faster recovery time, less pain, and a lower risk of some complications, such as infection.
In some cases, your doctor may combine a minimally invasive procedure with an open surgery. In addition, your doctor may decide after beginning a minimally invasive technique that open surgery is necessary to safely and most effectively complete your surgery. Your surgeon may also decide after beginning a that a is a better option for you. Discuss these possibilities with your doctor before surgery.
Your doctor will explain which procedure is best for youtotal or partial, and open or arthroscopic knee replacementbased on your diagnosis, age, medical history, general health, and possibly your personal preference.
What Are The Benefits Of Minimally Invasive Surgery Techniques
The minimally invasive surgical techniques currently used for knee replacement surgery allow for a shorter hospital stay. The average stay is 4 days. Minimally invasive techniques also decrease the risk of bleeding recovery is faster and less painful. 48 hours after surgery, most patients control pain with paracetamol and conventional anti-inflammatory medication.
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.
- Walking aids or supports and bracing.

No 7 A Fresh Pair Of Shoes
If youre like me, maybe you have a pair of shoes that you love. Maybe its the look, or maybe their comfortable so you keep them clean and looking like new.
Most people dont realize it but shoes wear down over time. We tend to get comfortable with our shoes plus they can be a considerable investment .
During your rehabilitation, you should be walking and doing physical therapy. Dont take my word for it. According to Livestrong, running shoes should be replaced every 300-500 miles. Of course you wont be running but even if you walk, youll reach 300 miles in no time at all.
For your TKR recovery choose a pair of shoes that are for exercise these can be worn around the house as well. We like a good pair of Nike Air Max because of the extra air cushion in the heel.
What The Procedure Is Like
Also called arthroplasty, knee replacement is a procedure to resurface the damaged parts of your knee that have been causing you pain.
The knee is the meeting place for three basic bones: the tibia and femur meet at the joint and are each capped with cartilage to absorb the shock of everyday movement. Resting between them is a freestanding bone called the patella . Often using a spinal anesthetic like an epidural used in childbirth a knee replacement procedure involves an incision over the knee that allows your surgeon to resurface the tibia, femur, and patella with metal and plastic components to restore the cushioning you need to move your knee comfortably.
There are two general kinds of knee replacement surgery: partial and total.
In a partial knee replacement , only a portion of the knee joint is replaced. This procedure may be recommended for patients who have damage limited to just one area of the knee. Because a partial knee replacement is done through a smaller incision, the recovery time in the hospital is often shorter and people can resume their usual activities sooner. However, more surgery may be needed in the future if other parts of the knee become damaged.
Your surgeon will discuss which type of surgery is right for you based on your medical history and risk factors.
While patients will need help in the first weeks after surgery, most people will get their feet under them and regain independence at about six weeks after the procedure.

What Is Knee Replacement Surgery
Knee replacement is where portions of the bones that form the knee joint are removed and replaced with artificial implants. It is performed primarily to relieve knee pain and stiffness caused by .
Most people who get this surgery have advanced knee arthritis, in which the knee cartilage is worn away and the surface of the knee becomes pitted, eroded, and uneven. This causes pain, stiffness, instability and a change in body alignment. Knee replacement surgery can also help some people who have a weakened knee joint caused by an injury or other condition.

Looking For Alternatives To Total Knee Replacements
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.
No 6 Walking Poles Or A Cane
Whether youre a young guy/gal or a senior like me, the early days after surgery will take a toll on you. Your balance will be slightly off as you manage the pain from TKR. The pain will gradually subside and your body should quickly adjust to its new knee. Even months after recovery youll want some support and thats why walking poles are a must-have item after knee replacement.
Even patients in top shape shouldnt be ashamed of using a little help. A cane in the weeks following surgery will help take some pressure off the knee although it will put more pressure on your arm.
Walking sticks can also be used while around the house or exercising outside. Unlike canes, walking poles come in a pair. Feel free to only use 1 or both depending on the situation.

While walking/hiking they can help with shock absorption. Just as important, the might help you avoid a fall and further injury to your knee or hip.
Ive used walking poles for a number of years. They are lightweight so my arms dont fatigue when using them and I notice my knee is less sore the following day after Ive used them.

Tests Before Knee Replacement Surgery
About six weeks or so before your operation you will have an appointment for a ‘pre-admission’ or ‘pre-assessment’ clinic. At this clinic a nurse will assess your fitness for your knee surgery.
There are several tests that may be needed and they include:
- Blood tests – to check that you aren’t anaemic and that your kidneys and liver are working well enough for you to undergo the operation.
- Urine test – to make sure you haven’t got a urine infection and that there isn’t any glucose in your urine.
- Blood pressure.
- Infection screen – this includes looking for meticillin-resistant Staphylococcus aureus . MRSA is a germ that is difficult to treat and can cause complications of a knee replacement.
- A heart tracing .
You may have the chance to speak with an anaesthetist, physiotherapist, occupational therapist or social worker at this clinic but this isn’t always possible.

Can You Wait Too Long To Have Knee Replacement
Undergoing joint replacement too early is not ideal as the artificial joints may wear out after 10 to 20 years, thus requiring a second surgery. On the other hand, waiting until end-stage arthritis or until you cannot handle the pain anymore is also less than ideal as the benefits of the surgery may be limited.
Which Type Should I Have
Your surgeon will discuss this with you. It will depend on how much of your knee is affected by arthritis – it may not be possible to know this until your surgeon has started your operation.
If you have a partial knee replacement it is more likely that you will need to have it done again, than if you have a total knee replacement . Sometimes the reason for choosing to have a partial knee replacement is that it leaves the option to have a TKR at a later date. However it’s also more likely that you will need to have your total knee replacement re-done, if you had a partial knee replacement done before having your total knee replacement.
There are over 150 different designs of knee replacement and some of the differences between all the different types and makes of knee replacement parts aren’t known, particularly how they perform in the long term. In many countries, registries have been set up so that anyone who has had a knee replacement is entered into the register. The information collected is used to monitor how their replacement is performing. In the UK, patients also enter information about their health and quality of life before and after their operation.
A study of over 500 patients with osteoarthritis of the inner part of their knee has compared the effectiveness of total and partial knee replacement. The two groups were followed up five years after surgery, and asked to complete questionnaires about pain, activity and day-to-day living.

Determine Your Insurance Benefit
Your insurance coverage is a practical matter. To receive the most insurance benefits and pay the least out-of-pocket for your surgery, you need to choose a knee surgeon that participates in your plan.
But keep in mind, just because a doctor participates in your insurance plan doesnt mean he or she is a high-quality doctor. You still need to consider the doctors experience and expertise.
Use Pain Medications With Care
Except in very rare cases, the American Association of Hip and Knee Surgeons advises against using opioid medications for knee osteoarthritis. Opiate pain relievers, in addition to being addictive, are not proven to address knee pain over the long term any better than nonsteroidal, anti-inflammatory drugs .
Though safer than opioid drugs, NSAIDs arent for everyone, and Valaik advises caution in using them. Even over-the-counter drugs like naproxen and ibuprofen can have side effects, so check with your doctor, he says.
You can get an increase in blood pressure with NSAIDs. Larger studies have linked some of these pain relievers with a small increase in the risk of heart attack.
And the more you take, the more likely you are to have heartburn, stomach irritation or even bleeding ulcers, he notes.

How Long Do Knee Implant Last
Despite the fact that knee implants have a limited life, current materials are increasingly resistant. The average duration of knee implant is estimated to be between 15 and 20 years, even when subjected to regular physical activity. Some factors that influence its duration are: the material and fixation used the weight of the patient and the physical activity they perform. A knee implant can last less when a complication arises. But there are also cases in which it can go up to 25 years.

The National Joint Registry
The National Joint Registry collects details of knee replacements done in England, Wales, Northern Ireland and the Isle of Man. Although it’s voluntary, it’s worth registering. This enables the NJR to monitor knee replacements, so you can be identified if any problems emerge in the future.
The registry also gives you the chance to participate in a patient feedback survey.
It’s confidential and you have a right under the Data Protection Act to see what details are kept about you.
When General Anesthesia May Be Needed
Despite the reasons to consider regional anesthesia, there may be times when general anesthesia is either favored by a patient or doctor, or medically necessary:
- Medical conditions: General anesthesia may be preferable for someone who’s had significant spinal surgery such as a lumbar fusion, which can make regional anesthesia more difficult. Spinal deformities, including scoliosis, may also make regional anesthesia more challenging. Also, medical conditions such as aortic stenosis make general anesthesia a safer option.
- Patient anxiety: Many patients who choose general anesthesia do so because they simply understand that option better than regional anesthesia. They could also be anxious about having a spinal injection. If you have questions, speak with your doctor to learn more about how regional anesthesia is administered and the effects it can have.

What Happens After Total Knee Replacement
Talk with your healthcare provider about what you can expect after your surgery. You may have significant pain around your incision after your procedure, but pain medicines may help to relieve your pain. You should be able to get back to a normal diet fairly quickly.
You may get imaging, like an X-ray, to see the results of the surgery. You might be able to go home within a day or two.
Your provider will let you know when you can put weight on your leg. You may have specific instructions about limiting your movements. You might need to use a cane, walker, or crutches for a few days or weeks. A physical therapist can help you maintain your range of motion and strength. You should be able to go back to most light activities within a few weeks. During this time, you may find it helpful to have some extra help at home.
You might have some fluid draining at the incision site. This is normal. Let your provider know right away if you have an increase in redness, swelling, or draining at the incision site. You should also let your provider know if you have a high fever, chills, or severe pain that does not improve.
Make sure to keep all of your follow-up appointments with your surgeon. You may need to have your stitches or staples removed a week or so after your surgery.
Most people note a significant decrease in their pain following a total knee replacement. You may have some remaining stiffness in the joint, as well as more limited range of motion.
