Do Follow Your Doctors Instructions On Caring For The Wound
To avoid post-op infection, be sure you understand how and when to change your bandage. If the skin aroundthe wound becomes red or drains, or if you develop a fever and chills, call your doctor right away. To avoidcomplications of a clot, call your doctor if your leg is tender, swells unduly below or above the knee, orif you develop pain in your leg or calf.
What Does Total Knee Replacement Surgery Involve
In knee replacement surgery the arthritic ends of the femur and tibia are removed or resurfaced, and replaced with artificial surface metal alloy implants. Sandwiched between the implants is a polyethylene spacer which acts as a cushion, replacing the function of the articular cartilage. It is similar to a dentist crowning a tooth, and modern knee replacements may be described as resurfacings. The kneecap may also be replaced with an artificial implant. Mr Rajaratnam favours the Zimmer Biomet Persona and Vanguard system implants, potentially used in conjunction with Signature Personal Specific Instrumentation which gives very accurate implant alignments.

When Will A Surgeon Decide A Knee Replacement Is Necessary
A knee replacement a major surgery that involves replacing either the damaged part of or the entire joint with a prosthesis has become a routine procedure in ambulatory surgery centers and many hospitals in the United States.
There is no doubt that a knee replacement is safe and effective: its success rates and quality-of-life improvements of knee replacement surgeries are remarkably high, with over 90 percent of patients reporting that their knee replacements are still functioning 15 years after their surgery. However, surgeons dont typically use it as a first-line treatment option, mainly due to its risks of complications that are inherent in any type of surgical procedure.
So, when exactly is a knee replacement necessary? Your surgeon will only recommend a knee replacement when:

Living With A Knee Replacement
Your doctor may want to see you from time to time for several months or more to monitor your knee replacement. Over time, you will be able to do most of the things you could do before surgery.
Controlling your weight will help your new knee joint last longer.
Stay active to help keep your strength, flexibility, and endurance. Your activities might include walking, swimming , dancing, or golf. You could also try cycling on a stationary bike or on level surfaces.
For at least 2 years after your surgery, your doctor may want you to take antibiotics before dental work or any invasive medical procedure. This is to help prevent infection around your knee replacement. After 2 years, your doctor and dentist will decide whether you still need to take antibiotics. Your general health and the state of your other health conditions will help them decide.
Is Knee Replacement Treatment A Major Operation
Chronic knee pain is a common problem, especially among athletes and active adults. Most often, it is due to general wear-and-tear arthritis in the knee joint resulting from daily activities such as walking, standing, bending, and lifting, or the result of an injury sustained during athletic activity.
If your knee pain is constant or severe, and is combined with swelling and stiffness in your knee joint, it may be reducing your mobility to the point where it interferes with your work, social life, everyday tasks, and your general quality of life. If this is the case, your orthopedic doctor may recommend knee replacement surgery if other forms of pain-relief treatment fail to improve your condition and x-rays show that you have bone-on-bone arthritis.
However, isnt knee replacement surgery considered a major operation? The short answer is yes, a knee replacement has become very routine, but it is still major surgery. Lets talk about why knee replacement may be necessary, how it is performed, how it can provide lasting pain relief and restored mobility, and where you can go in Raleigh and across the Triangle for outstanding orthopedic treatment.

What Is An Artificial Knee And How Does It Stay In Place
Artificial knee implants consist of metal and medical-grade plastic called polyethylene.
There are two ways of attaching the components to the bone. One is to use bone cement, which usually takes about 10 minutes to set. The other is a cement-free approach, in which the components have a porous coating that allows the bone to grow onto it.
In some cases, a surgeon may use both techniques during the same operation.
Any operation done with anesthesia has risks, although it is rare that severe complications result from any type of anesthesia.
The options for TKR include:
- general anesthesia
- spinal or epidural
- a regional nerve block anesthesia
An anesthesia team will decide on the most suitable options for you but most knee replacement surgery is done using a combination of the above.
Focus On Your Surgeon Not On The Device Or Technique
Newer technologies like computer navigation can help surgeons be more precise in how they position the implant components during knee replacement surgery. But theres a lot of information to sift through.
Between advertising, the internet and conversations with other people whove had knee replacements, you may have questions about your prosthesis and your surgeons technique.

What Perioperative Advances Have Enabled Same
The most common barriers to discharge in patients undergoing total joint arthroplasty are hypotension, pain and nausea. However, greater uptake of minimally invasive surgical approaches has allowed patients to benefit from decreased soft-tissue damage, reduced blood loss, less postoperative pain and quicker mobilization after surgery., Many of the studies that have assessed the feasibility and effectiveness of same-day discharge have used either the anterior approach,,, a 2-incision technique, , or minimally invasive posterior approaches for total hip arthroplasties, and quadriceps-sparing approaches, for total knee arthroplasties. Although use of minimally invasive approaches is important, perioperative innovations in managing blood loss and optimizing analgesia have contributed most substantially to making same-day discharge arthroplasties possible.
A vital advance in minimizing perioperative blood loss has been the routine use of tranexamic acid, an antifibrinolytic agent, often given before surgical incision, which binds to plasminogen and prevents fibrin degradation. Recent meta-analyses have shown strong evidence that tranexamic acid, given topically, orally or intravenously, substantially decreases blood loss in both total hip and total knee arthroplasty, with an associated decreased risk of transfusion.,
How Much Does A Private Knee Replacement Cost
Private Healthcare UK suggests that the national average cost of knee replacement varies by region and hospital. For the most experienced and highly qualified service, with first class facilities in popular areas, you would expect to pay between £11,000-£14,000. This includes all hospital, surgeon and anesthesia charges for the episode of care.

Dr Jaffes Belief On Outpatient Surgery
After more than 25 years as a joint replacement surgeon, Dr. Jaffe finds that patients are usually better off recovering from joint replacement surgery in the comfort of their own home. Like any surgery, the patient must meet certain criteria to qualify for the outpatient option. Typically if a patient is generally healthy and has a stable support system, they will be eligible to receive the surgery on an outpatient basis.

How Much Pain Will I Have After Surgery
There will definitely be some pain after your operation but your surgery team will do everything possible to keep it manageable and minimal.
You may receive a nerve block prior to your operation and your surgeon may also use a long-acting local anesthetic during the procedure to help with pain relief after the procedure.
Your doctor will prescribe medication to help you manage the pain. You may receive this intravenously immediately after surgery.
When you leave the hospital, the doctor will give you pain relief medication as pills or tablets.
After you recover from surgery, your knee should be significantly less painful than it was before. However, there is no way to predict the exact results and some people continue to have knee pain for many months after their operation.
Following your doctors instructions after surgery is the best way to manage pain, comply with physical therapy and achieve the best result possible.
If you have had a general anesthetic, you may wake up feeling a bit confused and drowsy.
You will probably wake up with your knee raised to help with swelling.
Your knee may also be cradled in a continuous passive motion machine that gently extends and flexes your leg while you are lying down.
There will be a bandage over your knee, and you may have a drain to remove fluid from the joint.
If a urinary catheter was placed, a healthcare professional will usually remove it later on the day of your operation or the next day.

The Benefits Outweigh The Risks
Your knee replacement surgeon will also have to consider certain factors, such as your age, overall health, and activity level to determine the necessity of and your eligibility for the procedure.
While anyone of any age can undergo knee replacement surgery if their condition calls for it, the procedure is usually carried out on older adults, between 60 and 80 years of age. Since younger individuals are generally more active, they tend to require revision surgery sooner.
A knee replacement surgeon will thoroughly assess your individual circumstances and condition to see if the benefits do outweigh the risks.
How Long Is Recovery From A Knee Replacement
The most critical period of recovery occurs during the first 3 months, when you are working hard to decrease pain and swelling, improve range of motion and wake up the muscles around the knee using physical therapy, home exercises and often a stationary bicycle.
Most people are able to return to work within a month, if their job does not require them to stand all day or lift, push or pull heavy objects. The majority of patients continue to take over the counter medications and ice daily for several months. Some patients are able to return to activities such as light hiking after just a few months.
There will be days and nights during those first few months that you will wish you had not had the surgery, but in the end, most people comment they wonder why they waited so long. You may continue to see improvements for 1-2 years after surgery as you regain overall strength and endurance.

Undergoing Total Knee Replacement For Knee Arthritis
Experts estimate more than 7% of people in their 70s and 10% of people in their 80s have had a knee replacement.1 The surgery is done to alleviate pain caused by moderate to severe knee arthritis.
More than 90% of knee replacement surgeries are considered successful2 , meaning that after recovery patients have both:
- Less knee pain
- Improved knee function
While common, total knee replacement is a major surgery, and recovery requires several months of physical therapy. For these reasons, patients are asked to commit efforts to non-surgical treatments before considering knee replacement.
Are There Any Reasons Why I Cant Have A Knee Replacement
Unfortunately, some people may not be able to have a knee replacement even though their arthritis is very bad. This may be because:
- your thigh muscles are very weak and may not be able to support your new knee joint
- there are deep or long-lasting open sores in the skin below your knee, increasing your risk of infection.

Understanding Joint Replacement Surgery
Hip and knee joint replacement surgeries are among the most common and successful surgical procedures in the United States. More than 190,000 total hip replacements and more than 500,000 total knee replacements are done each year in the US.More than 1,000 such procedures are done each year at the Wellstar Center for Joint Replacement, which holds Joint Commission Disease Specific Care Certification in total hip and total knee replacement.The procedures are most typically performed to ease the pain caused by osteoarthritis.
What Is Involved With The Pre
Before surgery, the joints adjacent to the diseased knee are carefully evaluated. This is important to ensure optimal outcome and recovery from the surgery. Replacing a knee joint that is adjacent to a severely damaged joint may not yield a significant improvement in function as the nearby joint may become more painful if it is abnormal.
- Furthermore, all medications that the patient is taking are reviewed. Blood-thinning medications such as warfarin and anti-inflammatory medications such as aspirin may have to be adjusted or discontinued prior to knee replacement surgery.
- Routine blood tests of liver and kidney function and urine tests are evaluated for signs of anemia, infection, or abnormal metabolism.
- Chest X-ray and EKG are performed to exclude significant heart and lung disease that may preclude surgery or anesthesia.
- Finally, a knee replacement surgery is less likely to have a good long-term outcome if the patient’s weight is greater than 200 pounds. Excess body weight simply puts the replaced knee at an increased risk of loosening and/or dislocation and makes recovery more difficult.
Another risk is encountered in younger patients who may tend to be more active, thereby adding trauma to the replaced joint.

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
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 .
Why Have Knee Replacement Surgery
There are three common reasons for the procedure:
Osteoarthritis: this type of arthritis is age related, caused by the normal wear and tear of the knee joint. It mostly affects patients aged over 50 years, but younger people may have it.
Osteoarthritis is caused by inflammation, breakdown, and the gradual and eventual loss of cartilage in the joints. Over time, the cartilage wears down and the bones rub together. To compensate, the bones often grow thicker, but this results in more friction and more pain.
Rheumatoid arthritis: also called inflammatory arthritis, the membrane around the knee joint to become thick and inflamed. Chronic inflammation damages the cartilage, causing soreness and stiffness.
Post-traumatic arthritis: this type of arthritis is due to a severe knee injury. When the bones around the knee break or the ligaments tear, this will affect the knee cartilage.
