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.

Knee pain: causes and tips to manage knee pain

The knee is the largest joint of the body and is made up of upper and lower bones that are separated by two discs known as menisci. While minor knee pain may be experienced by many people, it should be handled with medical intervention when it becomes a serious and debilitating problem. Sudden injury or injury due to overuse as well as myriad conditions that affect the joints and muscles can bring about knee pain. Underlying conditions like osteoporosis or arthritis, which affect the bones and joints, can also cause knee pain. The symptoms include painful swelling and stiffness as well as severe discomfort. Let us learn more about the causes of knee pain and the ways in which it can be managed-

Injury: exercise and sports injuries are one of the most common causes that can be the start of acute knee pain, as well as chronic condition. These kinds of injuries can affect the ligaments and cartilage which leads to severe pain. The pain can even affect the way one functions in one's daily life. Knee ligament injuries can also cause this kind of pain. These ligaments are bands of tissues that connect the thigh bone with the lower leg bones. Sprains and tears in the acl or pcl are common in sports injuries, and may even require surgery in many cases. Knee cartilage tears can also take place in the hard yet flexible cartilage of the knee which can affect the meniscus around the knee. This condition may also require surgery.

Arthritis: this condition can affect the knees specifically and is one of the most common types of arthritis. This is a chronic condition which gets progressively worse over time and may even require surgery. Stiffness and inflammation are common symptoms. Rheumatoid arthritis is also a degenerative auto-immune disease that can affect the knees and cause knee pain. Furthermore, post traumatic arthritis can also be experienced after an injury. Osteoarthritis is another common condition that leads to knee pain. It basically occurs due to wear and tear of the knees over a prolonged period and is usually experienced by patients over the age of 50.

Managing knee pain: while pain medication and anti-inflammatory drugs may be prescribed for most cases, along with surgery in the long run, it is also possible to manage knee pain with the help of better lifestyle choices like regular knee and muscle strengthening exercises as well as rest - rest, ice, compression and elevation. These methods can help in relieving inflammation and pain. But very severe cases will require medical intervention, so it is imperative to get in touch with your doctor if the condition does not improve.

Knee Pain: Causes and Tips to Manage Knee Pain

Knee is a complex structure of your body made up of bones, ligaments, tendons, articular cartilage, muscles and meniscus.

The most common shoulder injuries are stated below-

Dislocation- Sometimes joints may get dislocated from their usual alignment
Fractures- Fractures of the collar bone, humerus and scapular fracture
Frozen Shoulder- It occurs due to the stiffness of the shoulder joint
AC Joint Injury- The ligaments may get injured in this type of an injury. It is common in sportsperson or may also happen due to falling down
Shoulder Impingement- In this case the muscles gets injured
Rotator Cuff Disease (Tendinitis and Bursitis)- In tendinitis of the shoulder, tendons become inflamed (red, sore, and swollen) from being pinched by parts around the shoulder. However, Bursitis occurs when the bursa, a small fluid-filled sac that helps protect the shoulder joint is inflamed.
Rotator Cuff Tear- Rotator cuff tendons can become inflamed from frequent use or aging. Sometimes they are injured from a fall on an outstretched hand.
Treatment of Shoulder Injuries-

Early detection is the key to preventing serious shoulder injuries.
Shoulder Exercises
Anti-inflammatory medication also may be prescribed to reduce pain and swelling.

Suffering from Knee Pain - Know What Causes it? 

Bones are quite literally the support system of the body, so it's super important to keep them strong and healthy. Strength is not a goal you achieve in a day, week or month. It is a way more rigorous process that has to go on for years. The growing age of your life matters the most; it is at this point that you can make your bones strong. Bone strength should also be maintained in certain ways. Child or adult, you must aim for both mental and physical strength.

Here are some tips to make deposits in your bone bank for a healthier future.

1. Know your family history: as with many medical conditions, family history is a key indicator of bone health. Those with a parent or sibling who has or had osteoporosis are more likely to develop it. So, how's your bone density, grandma? might seem like an awkward question at thanksgiving dinner, but ask anyway before she passes the gravy.

2. Boost calcium consumption: when most people think bones, they think calcium. This mineral is essential for the proper development of teeth and bones. But calcium isn't the end-all, be-all bone loss cure. The key might be to help the body absorb calcium by pairing calcium-rich foods with those high in vitamin d. Foods that are good sources of calcium include yogurt, cheese, milk, spinach and collard greens.

3. Don't forget the vitamin d: where there's calcium, there must be vitamin d: the two works together to help the body absorb bone-boosting calcium. Boost vitamin d consumption by munching on shrimp, fortified foods like cereal and orange juice, sardines, eggs (in the yolks) and tuna, or opt for a vitamin d supplement. The body also produces vitamin d when exposed to the sun - 10 to 15 minutes of exposure three times per week will do. Vitamin d's importance to bone health has been proven in studies on  seasonal bone loss - elderly people can lose more bone mass during the winter because of lack of sun exposure.

4. Make exercise a priority: seriously regular exercise is to keep a number of health issues at bay, and bone health is no exception. In fact, living a sedentary lifestyle is considered a risk factor for osteoporosis. What type of exercise is most effective? weight-bearing exercises like running, walking, jumping rope, skiing and stair climbing keep bones strongest.

5. Consume less caffeine: caffeine does have some health benefits, but unfortunately not for our bones. Too much of it can interfere with the body's ability to absorb calcium. Drinking more than two cups of coffee per day accelerated bone loss in subjects who also didn't consume enough calcium. Also more than 18 ounces of coffee per day can accelerate bone loss by negatively interacting with vitamin d. So enjoy the java, but keep it in moderation and consume enough calcium, too.

6. Quit smoking: here's yet another reason to lose the cigarettes: multiple studies have shown that smoking can prevent the body from efficiently absorbing calcium, decreasing bone mass.

6 Things to Do for Strong Bones

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.
