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

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

Pregnancy places a lot of demand on the expectant mother. While the emotional demands are not very evident, the physical ones are. The mother has to ensure that the developing baby gets all the required nutrients through her. Some of them are very critical, and not getting adequate amounts of these manifest as problems, which cannot be rectified later. Calcium supply and associated problems that may arise is one such example.
If there is a reduced supply of calcium and the bones and teeth are not formed properly, taking any amount of calcium is not going to correct the situation later, after delivery.

The bones which are forming in the developing baby are dependent on the mother for adequate supply of calcium. It is common knowledge that calcium is an integral component of bones, teeth, and skeleton. Hypocalcemia, which is a condition where there is reduced amounts of calcium in the body, can be quite severe during pregnancy.
In addition to the growing baby s needs, calcium also plays a vital role in the pregnant mother for muscular contractions, nerve conduction, hormone secretion, and blood clotting. So adequate intake of calcium during pregnancy is essential.
Now, the question arises as to how much calcium is good enough. For a normal female, about 1000 mg of calcium is required on a daily basis. This goes up by another 200 to 300 mg for a pregnant woman, especially during the third trimester when the bone and teeth formation is in full speed. This extra amount of calcium should be continued even after pregnancy, as calcium continues to be provided to the baby during the lactation phase.

Some of the symptoms of reduced calcium intake during pregnancy are aching muscles, brittle nails, weakened bones, severe cramping, and dry skin. If there is suspected hypocalcemia, it is best to seek medical advice. It is not advisable to take supplements without medical supervision. Increased amounts of calcium can produce a different set of symptoms.

While these are evident symptoms, there are other detrimental effects on the baby too. Calcium deficiency affects development of heart and associated structures and puts the newborn at a higher risk of developing hypertension. The baby s fat percentage and triglycerides are also increased. The bone mineral density is reduced. The delivery period could be prolonged, as muscular contractions and nerve conduction are severely impacted when there is less calcium in the system. Recovery from labor is also delayed.

It is possible that you are taking adequate amounts of calcium, but its absorption is affected. Reducing caffeine intake helps in better absorption of calcium. Iron, which is often given during pregnancy, prevents calcium absorption and so needs to be spaced out.

Calcium & Bone Disorders - How to Know If Your Are Suffering From Them?

We have 207 bones in the body and breaking of any one of them can be extremely painful. Broken bones are called fractures and are most often a result of accidents. The risk of breaking a bone depends largely on your age and fractures are most commonly suffered by children and elderly people. There are many types of fractures. The most important amongst these are:

Complete or incomplete fractures: This refers to the way a bone breaks. A complete fracture involves the breaking of a bone into two or more separate pieces while in an incomplete fracture, the bone does not break all the way through and may only be cracked.
Compound fractures: Compound fractures are also known as open fractures. This refers to fractures where the bone tears through the skin.
Simple fractures: Fractures where the bone does not tear through the skin are known as simple fractures. This can be further categorized as greenstick fractures, transverse fractures, oblique fractures and impacted fractures.
Severe pain is one of the most common symptoms of a fracture. Other symptoms include swelling or bruising over the bone area, loss of function and deformity. Any form of a fracture needs medical attention. In most cases, using a splint to reset and support the broken bones can help heal them. This process can be surgical or non-surgical depending on the extent of the fracture. In some cases a pin or metal plate may need to be implanted along with the bone to give them support while they heal.

Fractures can be easily prevented. In your home look out for things you could trip over or bang into. Keep all stairways clear of obstructions and do not use them when wet. Advise your children not to run in the house as tiles are slippery and they could fall and hurt themselves this way.

Follow general safety precautions like wearing a seatbelt while driving or wearing a helmet while riding a bike or bicycle. This can significantly reduce your chances of breaking a bone if caught in an automobile accident. 

The weaker your bones, the easier they are to break. Eat food rich in calcium and vitamin D to build stronger bones. Milk and other dairy products are rich in calcium while the best way to get vitamin D is by exposing yourself to the early morning sunlight.

If you suffer from osteoporosis, exercise regularly to improve your balance and increase the strength of your bones and muscles. Your doctor may also prescribe medication for the same.

Fractures - How They Can Be Prevented?

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.

Three Ways to Protect Your Knees

The knee is known as the largest and one of the most complex joints in the human body, and also one of the most vulnerable, as it supports the weight of the entire body. The knee joint is made up of several elements including the knee cap, meniscus, connective tissue, tendons, ligaments, cartilage, and muscles. Damage to any part of the knee can cause chronic pain. So how can you protect your knee from damage and injury? Take a look at these three points!

Dealing with Load: Weight is a big one. Carrying around extra pounds and kilograms can be detrimental for your knees in the long run. Your knee is not equipped to handle the excessive weight. It already supports three to five times your weight when you get up and walk around or indulge in some mild jogging. One must be careful of those extra pounds to take the load off the knee and keep it from falling prey to damage.

Exercise: Moderate to intense exercise is prescribed for one and all. This, of course, depends on one's overall health and age. If you are already suffering from joint pain, then you may want to go easy on the exercise with a focus on building muscle strength and foundation. If you are healthy, then some amount of daily exercise as a routine will keep those knees in prime working condition and well lubricated as well. Inactivity and a sedentary lifestyle can affect the knees very badly.

Do not Ignore: Warning signals such as chronic or acute knee pain should not be ignored. Remember to see a doctor or an orthopaedic specialist to find out if you have contracted an infection or if you may have suffered a fracture due to an injury. Also, it is important to take a bone density test regularly, especially after the age of 40 or for women going through menopause, as this will point to any deficiencies and even warn you in case there is any trace of osteoporosis.

Rest, exercise, and food should be kept in fine balance for a healthy body. These are a few measures that one can take to keep knee pain at bay. Yet, it is also advisable to speak with a doctor at length regarding measures to protect your knees.
