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 Living with a painful joint that prohibits you from working or participating in normal life activities is an outdated way of thinking.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!

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.





Why does PAIN occur? Understand the Mechanism of Pain

Causes and symptoms of knee pain

Knee pain is characterized by a feeling of pain in the knee joint caused by injury or overuse. The knee joint consists of small bone structures, the kneecap, supporting ligaments and cartilage of the knee. This joint bears the full weight of the body, which makes it very vulnerable to injury.

Causes of knee pain

Knee pain is usually caused by injuries to the knee such as exposure to a direct force on the knee, abnormal twisting of the knee or falling on your knees. Some causes of knee pain are -

Knee strains and sprains - Overworking the knee joints can damage the tissues of the knee joint resulting in knee sprains and strains

Osteoarthritis - it is condition where the protective cartilage around the kneecap is damaged, resulting in knee pain

Bursitis - Excessive movement of the knee or kneeling down for extended periods can irritate the bursa (a fluid sac below the skin above the knee joint) that causes swelling and pain, thereby giving rise to this condition

Gout - This condition is characterized by the accumulation of uric acid in crystal form around the knee joint, causing inflammation and pain

Tendon disorders - Tendons connect the muscles to the bones, and overworking the knee can cause the tendons around the knee to become sore and painful

Kneecap dislocation - Injuries may cause the kneecap to shift out of its position, this causes swelling and pain in the knee joint

Symptoms of knee pain

Severe knee pain can restrict movements such as walking or standing. The symptoms vary according to the extent of the damage suffered by the knee. Most common symptoms of knee pain are problems in climbing stairs, inability to extend the knees, limping and swelling of the knee joint. In some cases, knee pain may also cause fever.

Causes and Symptoms of Knee Pain

 Movement disorders    the term refers to a class of neurological conditions, which lead to either an increased/abnormal movement or a scarcity of involuntary and voluntary movements.

Types of Movement Disorders- 
The most common types of movement disorders are  
  Myalgia   More commonly known as muscle pain, myalgia originates in any part of the body. A person with myalgia will experience achiness and soreness in the muscles, which may range from severe to mild.

Myalgia does not occur from an underlying disease. Rather, the pain develops over time, mostly due to prolonged sitting, lying down, a strenuous physical activity, strains or sprains.

  Muscular dystrophy   This refers to a group of genetic disorders that lead to weakness and loss of muscle mass. The abnormal genes cause muscle degeneration and usually begins in early childhood. Myotonic, Facioscapulohumeral (FSHD), and Limb-girdle are a few forms of muscular dystrophy.

Muscular dystrophy is characterized by symptoms like   difficulty jumping and running, muscle stiffness and pain, walking on toes, waddling gait, trouble swallowing and breathing etc.

  Dystonia   The condition involves continuous involuntary muscle contractions with repetitive, twisting movements. Dystonia may affect either a specific body part (known as focal dystonia) or the full body (known as generalized dystonia).

  Huntington s Disease   This is an inherited, neurodegenerative condition, where the brain s nerve cells break down over time. Huntington s disease usually kicks in, in the 30s or 40s. The disease results in psychiatric and cognitive symptoms   amnesia, confusion, slowness in activity etc.

  Multiple System Atrophy   This is a rare neurological disorder, which affects both the autonomic nervous system   the part of the nervous system that controls involuntary actions like digestion and blood pressure   and movement. Multiple System Atrophy leads to movement disorders like Parkinsonism or ataxia.

Symptoms of this disorder include   double or blurred vision, visual disturbances, unsteady gait, loss of balance etc.

  Tourette Syndrome   This is a disorder of the nervous system, which occurs usually between one s childhood and teenage years. The disorder is associated with vocal sounds (vocal tics) and repetitive movements (motor tics).

Physiotherapy for Movement Disorders-
In most cases, movement disorders cannot be completely cured. However, with physiotherapy, you may be able to manage the symptoms and live a better life.

Physiotherapy is based on a few physical activities or mild exercises that help improve your joint movement and builds muscle strength. This particular treatment approach centres on  

  Exercises based on daily tasks that improve muscle strength
  Activities that improve your balance and reduce the chances of falling
  Exercises to gain control over the uncontrolled movement of legs, arms, and head
  Correct posture while standing or sitting to reduce pain and increase comfort
  Cueing, repetition and movement strategies to reduce the effects of freezing
  Participating in certain functional activities that make it easier for you to move around
  The repetitive movement to trigger pathways to the brain and improve movement accuracy
  Exercise to reduce fatigue and increase stamina
  Hydrotherapy and relaxation therapy to ease muscle stiffness

Neurological disorders affect people in different ways. Physiotherapy for movement disorders is tailored according to the patient s goal and needs so that they are able to achieve maximum physical potential.

Movement Disorders - Its Types, Symptoms & Physiotherapy Treatment!

Most bone fractures mend very easily with proper medical treatment and rest. However, in rare cases, a fracture caused by trauma may not mend even after adequate treatment. When a broken bone fails to heal, it is known as non-union. There are two major reasons for non-union:

  Bone lacks adequate stability

All broken bones require stability to heal. In case of a fracture, doctors place the dislocated bone in its original place and use an external device to hold the broken part in place. Usually, this stability is provided by a splint or cast, but can also be offered by frames and rods as well. However, if the broken bone lacks the required support, it may not set or heal properly, leading to the non-union.

  Fracture lacks proper blood supply

Even with proper stability, a broken bone requires a proper blood supply to start the healing process. The blood carries oxygen and other chemicals that aid in the repair of the bone and makes it crucial during the recovery stage. However, if the blood supply is disrupted, the bone cannot heal and leads to non-union.



Risk factors of non-union:

You are more likely to suffer from non-union if one or more of the following is true in your case-

  People who engage in cigarette smoking and any other form of nicotine addiction have a higher risk of non-unions after a fracture
  Older people can often face non-union, which is why fractures may take longer to heal in these people
  Severe anaemia can often restrict proper blood flow to the broken bone, thus inhibiting the healing procedure
  Similarly, people suffering from diabetes face a greater risk of non-unions
  Lack of proper nutrition may also be blamed for the non-union
  Non-union risks may increase because of side effects from certain medication, such as prednisone, ibuprofen, and aspirin. Consult your doctor in such a case, so that proper precautions can be taken accordingly.

Non-surgical treatment can be used for treating the non-union. Electromagnetic and ultrasound waves are passed through the skin and into the affected bone, in order to treat the non-union. In most cases, this treatment is very effective in curing the fracture. However, if the non-surgical treatment proves ineffective, surgical procedures, such as bone grafts and allograft can be utilized.

Trauma And Nonunion - The Various Risks Involved With It!

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.
