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 Replacement

Spine surgery is conventionally performed as  open surgery , which means the region being worked on is opened with a long entry point to permit the surgeon to view and access the area. Technical and scientific advances have permitted more back and neck conditions to be treated with a less obtrusive surgical technique. The minimal invasive spine surgery (MISS) does not include a long cut, and it prevents causing damage to the muscles around the spine. As a rule, this causes less pain after the surgery and a speedier and healthy recovery.

Spine surgery is normally suggested when non-surgical treatments like medicinal or exercise based methods have not helped in lessening the excruciating symptoms of your back problem. Moreover, surgery is just considered if your doctor can pinpoint the correct reason of your pain, for example, a herniated circle or spinal stenosis. 

MISS is also called less obtrusive spine surgery. In these procedures, surgeons utilise particular instruments to get to the spine through little cuts. The surgery process is as follows:

During the surgery, a little entry point is made and the tubular retractor is embedded through the skin.
It is also inserted into the delicate tissues down to the spinal cord.
This makes a passage to the little range where the problem exists in the spine.
The tubular retractor holds the muscles open and is set up all through the surgery.
The surgeon gets to the spine utilising the little instruments that fit through the focal point of the tubular retractor.
Any bone or disk material that is expelled goes out from the retractor.
Any gadgets needed for the fusion process, for example, screws or rods, are embedded through the retractor.
A few surgeries require more than one retractor.
Keeping in mind the end goal to see where to put the entry point and embed the retractor, the surgeon is guided by fluoroscopy.
This strategy shows ongoing X-ray pictures of the patient's spine on a screen throughout the surgery.
The surgeon additionally utilises a microscope to enlarge the view through the retractor.
Towards the end of the procedure, the tubular retractor is expelled and the muscles come back to their original position.
This restrains the muscle damage that is more ordinarily found in open surgeries.
It is very important to talk about these risks with your doctor before your surgery or procedure.

Infection: Antibiotics are consistently given to the patient some time before, during, and regularly after the surgery to reduce the danger of infections.
Bleeding: A specific measure of bleeding is normal; however, this is not commonly dangerous.
Pain in the grafted area: Some patients will encounter surgical pain at the bone joint site.
Recurring symptoms: A few patients may encounter a repeat of their side effects.
Pseudarthrosis: Patients who tend to smoke are more prone to pseudarthrosis. This is a condition wherein there is insufficient bone formation. In case that this happens, a minor surgery may be required.
Nerve damage: It is possible that the nerves or veins might be harmed during these operations. These complications are extremely uncommon.
Blood clots: Another complication is blood clots in the legs. This poses a threat because these clots can break off and settle in the lungs.

Today  working  usually implies sitting at a desk from morning to evening. While this may seem more comfortable than working in the fields, sitting at a desk can trigger a host of back problems.

World Spine Day-6 Back Saving Tips for People Who Sit at a Desk All Day

Bursitis is a disorder that is characterized by inflammation of a fluid filled sac called the bursa. Bursa is present in between various tissues such as muscles, tendons and bones where friction may occur. This sac cushions the tissues and prevents friction. The usual areas that are affected by this condition are hip, shoulder and the elbows.

The symptoms of bursitis are:
1. You will experience pain in the affected area
2. Tightness and stiffness in the area
3. Local swelling of the muscle
4. Redness of the area
5. Any physical contact with the area causes pain

Bursitis may also occur due to the following reasons:
1. Ageing results in loss of elasticity of the tendons, thus impairing their ability to tolerate any stressful activity
2. Sports such as baseball where you are required to throw the ball with force may lead to bursitis
3. If you do tasks that require kneeling down on a regular basis
4. Sitting on hard surfaces for extended periods of time
5. Abnormalities such as improperly placed joints
6. Inflammation from other conditions such as gout, thyroid disorders and rheumatoid arthritis may lead to bursitis

Treatment
The condition is treated by using a variety of methods such as exercise and medication. Antibiotics are used to treat any underlying infection causing bursitis. Injections may be administered to reduce inflammation in the affected area along with exercises to strengthen the affected muscle. In severe cases, the doctor may resort to surgery to treat this condition.

Prevention
You may use certain preventive measures to stay clear of bursitis. Some of them are
1. Lift with proper form: If you are lifting something heavy, then make sure you keep the spine straight and bend your knees slightly.
2. Take breaks: Don t remain in the same position for long duration, take small breaks and walk around to release the stress from your legs.
3. Exercise: Do strength building workouts to build strength in the joints. Include mobility and flexibility stretches in your routine to keep your joints healthy, thus increasing the range of motion.
4. Maintain optimal weight levels: If you are obese, then take steps to reduce your weight. Maintain a proper diet to check your waistline.

Bursitis - 4 Ways You Can Prevent it

People who suffer from arthritis are more likely to experience osteoarthritis symptoms. The intensity of the feeling of knee pain in winter is often linked to barometric pressure. In winter, there is a reduction in the pressure exerted by the air around us. This drop in pressure can cause the tissues around the joints to swell resulting in increased pain. The other possible cause of knee pain in winter can be explained from the influence of heat. Fluid in tissues becomes more viscous during winter. As a result of this increased viscosity, the elasticity of the muscles decreases, resulting in winter aches and pains. 
Some scientists believe that the higher pain intensity in winter is to be more of a psychological thing. Seasonal affective disorder is more during winter, and people suffering from mental depression seem to sense more pain during winter as the weather restricts outdoor activities. Improper intake of food also causes knee pain in winter due to undigested material. Even though winter arthritis is uncomfortable, the following tips help to make the joints work better and make you withstand the season easier.

Tips to Manage Joint Pain in Winters

Physical activity in winter can reduce winter aches and pains and enhance overall health benefits. Low impact activities like aerobics, swimming in a heated pool, weight training, and riding a stationary bicycle can reduce stiffness, increase the blood flow, and support the knees. Thus, winter arthritis can be well managed by doing exercises.
Diet also plays a vital role. Eating a balanced diet that comprised of low saturated fat, lean proteins, more fiber, and refined carbs helps to improve body functions during the winter. Drinking water throughout the day helps to reduce winter aches and pains. It is essential to consume easily digestible foods like vegetables. Consuming vegetables like carrots and cucumbers that have diuretic properties can help to eliminate waste products from the body.
Vitamin D deficiency may worsen osteoarthritis. It is necessary to take a supplement vitamin D or ensure to make your diet is vitamin-D rich. Fish oil is a potent source of omega 3 fatty acids. Increase your intake of milk, a rich source of protein and calcium that help to strengthen the bones. Exposing the body to sunlight help to obtain vitamin D.
Non-steroidal anti-inflammatory drugs such as aspirin and ibuprofen can be used to reduce inflammation and pain. Injecting a viscous substance can decrease the friction of the bones and ease the condition.
Home Remedies for Knee Pain in Winters

Wrap the inflamed knees with blanched cabbage leaves. This can cool down inflamed knees.  Aloe vera also helps to reduce inflammation.
Comfrey (symphytum officinale) can act as an anti-inflammatory agent. Create a compress using mashed root or comfrey tea soaked bandages can also be used to reduce inflammation.
Applying an ice-pack can help to reduce swelling and alleviate winter aches and pains. While applying ice-pack, ensure to cover the entire knee. Applying a bag of frozen peas to the area also works well. While using ice or heat therapy, make sure to do them carefully as over agressive and over doing it, can cause problems. 
Steam therapy also helps to reduce pain in your knees. Soak your knee in a steaming hot water for 15 minutes. Applying hot water bag also can relieve knee pain in winter effectively.
Winter aches and pains all over the body can be relieved by administrating massage therapy by a professional.
Avoid applying strain or pressure on your knees. Take adequate amount of rest to reduce pain and swelling.
These are basic guidelines to help you. Contact your doctor for further management.

Tips For Managing Joint Pain in Winter

People have a common perception that most injuries, medical conditions only affect those who spend several hours working outdoors. But what if we tell you that people who stay indoors- such as homemakers - are also susceptible to numerous health problems?

There s a saying:  Home is where the heart is.  But for countless homemakers, home is the place where  hurt  is! Scores of Indian homemakers encounter various injuries every year while engaging in household chores like cleaning and washing. The most common ones are-

Sprain- if you re a neat freak, you wouldn t mind spending half of your day cleaning the entire house. Here s a small tip- go slow if your cleaning duties include shifting heavy appliances and furniture from one place to another. There s a high chance that you may end up with a sprain injury. Sprains occur when you accidentally twist your ligaments. Another major cause of sprain injuries is a sudden fall. If you re mopping the floor or cleaning the bathroom, there s a fair chance that you may slip or lose balance. One must be cautious when working with water.
Back injuries- These are the most common types of injuries at home. Bending, lifting a heavy bucket or an abrupt movement, can strain your back muscles or ligaments leading to back injury. Many times the injury can result in a persistent, sharp stabbing pain, and hinder your usual routine.
Joint compression- Homemakers spend a considerable amount of time standing in the kitchen. As tiring as it is, standing for prolonged periods puts pressure on your joints- knee joint, hip joint as well as those in the feet and the ankle. This leads to wear and tear of the synovial joints, eventually causing them to tear. In due course of time, you will find it difficult to move around and walk even a meagre distance.
Prevention-
Starting to get worked up? Don t be. These problems can easily be prevented if you follow these steps-

Avoid overstretching, bending and twisting
Avoid lifting heavy weights. If possible, use a waist belt to keep away from traumatic injuries.
Keep your body weight in check. Mild exercises can help you with that.
Maintain a healthy diet- calcium intake can help your bones get stronger.
Use muscle braces to keep your joints protected.
Treatment-
The most preferred and effective choice of treatment for curing muscle injuries and joint inflammation is physiotherapy. Physiotherapy uses manual therapy, mechanical force and exercise therapy to promote mobility.

The most common method of treating such injuries is the RICE technique.  RICE  stands for Rest, Ice, Compression and Elevation. Keep the injured part at rest. Put an ice bag on the injured portion. Compress the injured area. Elevate the wound/injury for faster relief.
Anti-inflammatory drugs like Ibuprofen and Aspirin are prescribed to reduce inflammation and swelling. Painkillers can offer you instant relief from pain.
Physiotherapy treatment can effectively cure you of such injuries, that too in a short span of time. If you follow the treatment guidelines, recovery will take about 2-4 weeks.
