Myths about Total Knee Replacement

Myth#1 - Knee replacement is a surgery for old people. “I’m too young for a knee replacement.”
Fact - Candidacy for a knee replacement is not based on age, but on the person’s level of pain and immobility. Living with a painful joint that prohibits you from working or participating in normal life activities is an outdated way of thinking. Age is not necessarily a limiting factor. Often times, a patient is actually fearful about the uncertainty of surgery. Once they are able to resume many of the activities they enjoyed before the surgery, with increased mobility and with less pain, they are very happy they had the surgery. The quality of life one achieves by living without knee pain is priceless.

Myth#2 - “I should wait as long as possible to undergo knee replacement surgery” 
Fact - You don't need to suffer by waiting until the pain is intolerable. The longer life of joint replacements enables people to consider surgery earlier and at a younger age. Osteoarthritis is a degenerative disease that continues to damage the joint and delaying surgery makes both surgery and return to activity more difficult. Delaying surgery lowers a patients’ quality of life not only before the operation, but even for up to two years following surgery.

Myth#3 - “I should continue with medications as long as possible”
Fact - Medicines including painkillers just give symptomatic relief for a temporary duration and prolonged usage is riddled with serious side effects such as renal failure, peptic ulceration  etc. All these medicines are NOT curable.

Myth#4 - Alternative therapies such as acupressure, ozone treatment, massage beds, oils, laser therapy, magnetic therapy; braces will cure my advanced arthritis and knee pain.
Fact - Till date there is NO cure for advanced knee arthritis and these alternate therapies are not backed by established scientific data. All these modalities give temporary pain relief in early to moderate arthritis for some duration only and are NOT curative. Often times, a patient who is actually fearful about the uncertainty of surgery lands up trying these in order to avoid surgery. 

Myth#5 - After a knee replacement, it takes months to recover.
Fact - Depending on the activity, most patients who undergo knee replacement are able to perform routine tasks within a few weeks. A return to rigorous activity takes only a few months. One becomes independent for himself before discharge from hospital. There’s no prolonged best rest required after the surgery.


Myth#6 - After knee replacement, I’ll have to give up some activities and sports.
Fact - You have a high probability of getting back to activities like brisk walking or cycling in 6 to 12 weeks. It will take a bit longer to return to more rigorous activities and contact sports. Squatting and sitting cross legged though possible but at best should be kept to minimal.

Myth#7 - Knee replacement surgery leaves a large scar that is noticeable.
Fact - Scarring is minimal compared to traditional surgery. In fact, the scar is typically only 3 to 5 inches long. As time passes, the scar will fade and become less noticeable.

Myth#8 - Knee replacement is a very painful surgery. There is lots of pain in post operative period.
Fact - With modern day pain management such as in a multimodal approach, ensures that the patient does not feel any pain in post op period and has a smooth recovery.

Myth#9 - Knee replacement is done one at a time.
Fact - Both the knees can be operated at the same time if the patient does not have significant co morbidities and is deemed fit to undergo the procedure by the doctor.

Myth#10 - The new knee lasts for 5-6 yrs. only.
Fact - With modern day precision including computer assisted knee replacement and advancement in biomaterials, the survivorship has increased considerably. Today's joint replacements last 25 years or longer and, for most people, will last a lifetime.

Myth#11 - Knee replacement cannot be done a second time.
Fact - Knee replacement can be done multiple times what is called as a revision joint replacement surgery with good survivorship.

Myth#12 - “I am obese, I cannot undergo Knee replacement surgery.”
Fact - Knee replacement can be successfully done in an obese patient though the recovery is somewhat prolonged and might require additional implants. However, patients who are morbidly obese and have restricted mobility primarily due to obesity are better off after a bariatric procedure.

Myth#13 “I have diabetes or hypertension or heart ailment, so  I cannot undergo Knee replacement surgery.”
Fact  - diabetes hypertension or heart.

 13 Myths About Total Knee Replacement (TKR), Busted!

The knee is the largest joint in the human body and is a complex structure formed of bone, muscle and cartilage. Development of pain in the knees can be caused by numerous factors such as aging, injuries, diseases, dietary deficiencies, etc.

Arthritis is the most common cause of knee pain and usually affects the elderly and aged. It occurs due to an inflammation of the joint and causes pain, swelling, redness and inflexibility of the knees.

What are the factors that determine treatment method?

Diagnosis for knee pain varies from patient to patient as each case is different and must be approached differently. Some of the factors that determine the treatment method are as follows:

- Cause of the problem
- Nature and intensity of pain
- Age of the patient
- Medical history of the patient
- Diet and lifestyle of the patient

There are a number of different types of arthritis which can affect the knees in different ways and, consequently, require different types of treatment methods.

What are the various treatment methods for knee pain?

1. Conventional Remedies - These are used in case of conditions that are not too severe or chronic. It includes keeping on bed rest, using an ice pack, taking a painkiller and anti-inflammatory medicines, wearing knee braces, etc.

2. Physical Therapy - There are many stretching and strengthening exercise routines that help alleviate knee pain and treat the condition. Recovery is achieved by making the muscles around the knees stronger and increasing stability and flexibility.

3. Injections to the Knees - A number of anti-inflammatory substances and supplements, as well as lubricants, can be injected into the knee joint which helps reduce pain and makes the joint more supple.

4. Stem Cell Therapy - This involves drawing platelets from the patient's blood and injecting it into the knee joint for repairing damage caused to ligaments, tendons or cartilage.

5. Surgery - Surgical procedures for treating knee pain include partial or complete knee replacements.



What kind of treatment does your knee pain require?

Calcium is known for its role in maintaining the bone health, from keeping your teeth stronger to normal functioning of the cells.  But there are various factors, which lead to a deficiency of calcium in the human body and paves the way for several complications.

Here are the top three signs that indicate you are suffering from calcium deficiency.

Difficulty in sleeping: Sleep is essential for your bone health and calcium is directly associated with your sleep cycle. The level of calcium in your bones rises and falls when you are asleep and it reaches its peak when you are in deep slumber. This indicates that when you are unable to sleep properly, it is a warning sign of calcium deficiency. There are various researches that have confirmed, that by increasing the level of calcium, it is possible to restore the normal sleep cycle of an individual. This is also related to the role that calcium plays in the production of a sleep hormone called melatonin. When the calcium content in the body is really low, this hormone is not produced, thus, making it difficult for a person to sleep.
Difficulty in losing extra pounds: Yet another frustrating aspect of any individual s life is the inability to shed off excess pounds. This issue is also linked with the lack of calcium supply in the body. The calcium that s stored in the cells assists in the processing and storage of fat. So the fat cells with high calcium content burn faster, making you lose weight. Thus, if you have trouble losing weight in spite of having a well-regulated diet and regular workout, it s a sign that you are suffering from low calcium.
Paresthesia: Though this ailment is not much heard of, it could be a sign of calcium deficiency. Paresthesia is a nervous disorder, which causes tingling sensation, tremors, numbness and loss of sensitivity. It could also lead to poor concentration, amnesia, confusion, hearing impairment, twitches and other physical as well as neurological impairment. This is because low calcium in the blood is connected with the health of your nerves.
The deficiency of calcium can manifest itself in different intensity, ranging from the non-existent to minimal to severe levels. Chronic calcium deficiency can lead to life-threatening diseases like rickets, osteopenia, and even osteoporosis. Therefore, you shouldn t ignore these signs and consult an expert without delay.

Calcium Deficiency - 3 Signs You are Suffering from it

Knee pain is something that can affect anyone - irrespective of their age. While sometimes it may be of minor importance - and can easily be handled by self-care, often, lingering pain is a manifestation of some other serious underlying problem, such as arthritis. In this case, it is imperative that you consult a doctor and take appropriate measures to combat it.

Causes :

Arthritis: The chief cause of lingering knee pain, arthritis itself can be of a number of types:
 Osteoarthritis, which is a result of deterioration of cartilages due to wear and tear
 Rheumatoid Arthritis, an inflammatory chronic disorder
 Septic Arthritis, causing pain, swelling and redness.
 Gout caused due to the development of uric acid crystals in the joints
Fractures: These are caused by the breaking up of the kneecap due to falls or collisions.
ACL Injuries: Caused due to the tearing of the anterior cruciate ligament (that connects the femur and the shinbone). Especially common in sportspersons such as footballers or basketball players.
Meniscus tears: The meniscus or the rubber-like cartilage (that acts as a shock absorber) can be torn by sudden jerks or excess pressure.

Symptoms:The major symptoms of knee pain include weakness, redness, instability, stiffness or the inability to properly straighten or move the leg. Often, a deformity is also visible, such as a bone sticking out of the leg - in which case it is advisable to consult a doctor immediately.

Possible risks :Factors which include the odds of being inflicted by knee pain and cause serious complications include :
Being overweight: This exponentially increases the stress or pressure that is applied on the knee joints - even in doing mundane tasks like walking up and down stairs.
Excessive physical activity: Some activities, such as sports apply excess stress on the knees as compared to other tasks.
Loss of muscle flexibility: Tightness or weakness in muscles causes increasing number of problems in the knees.

All About Knee Pain

Knee is a hinge joint where the lower leg bone tibia meets the thigh bone femur. During osteoarthritis, cartilage or ligament defects and degenerative arthritis, knee replacement surgery is recommended world-wide to get relief from extreme pain. Knee replacement surgery, also known as knee arthroscopy, is a surgical procedure, in which the affected knee joint is replaced with synthetic material. The most likely candidates for total knee replacement are the patients with severe destruction of the knee joint coupled with progressive pain and impaired function.

Modern technological advances have made computer assisted knee replacement surgery extremely popular around the globe. In this surgery, the surgeon is assisted by a computer to remove the optimum amount and angle of the bone, which otherwise is done by inspecting manually. This is an excellent example of surgery through small incision and it eliminates the chances of human error. A perfect alignment and balance is achieved and hence longevity is also increased to 20 - 30 years. Knee replacement surgery is also specific to gender as the anatomy of male and female patients is different.

There are many types of knee replacements, most common being the total knee replacement or Total Knee Arthroplasty. In addition, there is partial knee replacement, bilateral knee replacement, revision knee replacement and knee arthroscopy.

In knee replacement surgery, the worn out surfaces of joints of knee are replaced with artificial implant of plastic and metal. The lower end of the femur bone is removed and replaced with a metal shell. The upper end of the lower leg bone (tibia) is also removed and replaced with a channelled plastic implant with a metal stem. A plastic ball is also added under the kneecap depending on its condition. These artificial components are commonly referred as prosthesis. The design of these highly flexible implants replicate knee, with the rotating knee replacement implants assist in backward and forward swing of the legs.

Patients whose knee joints have been damaged by either trauma or progressive arthritis should consider total knee replacement surgery. Post-surgical hospital stay after knee joint replacement is usually three to five days. The surgery has a very high success rate and shows dramatic improvement after a month. This improvement is most notable one month or more after surgery. The pain caused by the damaged joint is reduced significantly when the new gliding surface is constructed during surgery. Initially, patient will walk with the help of a walking aid until the knee is able to support full body weight. After six weeks, patient can walk comfortably with minimal assistance. Patients with artificial joints are prescribed to take antibiotics during the course of any elective invasive procedures including dental work. Physiotherapy is an essential part of rehabilitation and it will increase the muscle strength and patient can enjoy most activities, except running and jumping.

Why does PAIN occur? Understand the Mechanism of Pain

Pain is an unpleasant and distressing physical sensation caused by disease or injury, which induces hurt and anxiety in those suffering from it.
There are many different manifestations of pain, ranging from short term (acute pain) to long term (chronic pain). Other classifications include pain in the internal organs (visceral pain), injured tissue (inflammatory pain), nerves (neuropathic pain), etc.

The reason for the occurrence of pain depends on the cause and kind of pain being experienced. In most cases, pain acts as a warning sign that the body has been afflicted by a disorder of some sort, which may have arisen due to internal sickness or external wounding. Acute pains are generally cured on their own through rest or simple medication. Chronic pains, on the other hand, are more complicated in nature and the treatment requires more elaborate diagnosis.

The mechanism of pain

Pain is an extremely personal and subjective experience and affects each individual to varying degrees. The pain signals, which can arise in any part of the body, travel through the spinal cord to the brain along thousands of specialized nerves and nerve fibres. In the brain, it is processed in the centres associated with anxiety, emotions, memory, appetite, etc. Signals and pain inputs are then returned from the brain to the spinal cord, which may heighten or diminish pain.

In some cases, pain may also be induced by damage to the brain and spinal cord, which happens after a stroke.
A constant barrage of pain signals may cause the cells at the end of nerve fibres to become over-sensitized. This is known as 'wind-up' and is one of the most common causes of chronic pain that occurs even though the root of the problem has been identified and treated.

The causes and effects of pain differ from case to case depending on the signals received by the brain and its interpretation. It affects the individual's day to day activities and if persistent, can also have a harmful impact on mental health and psychosis. Pain is always handled, diagnosed and treated differently in all patients by drawing out the best possible solution to the problem.
