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

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

Your knee is a very complex structure consisting of bones, ligaments, cartilage, tendons, muscles and meniscus. Most people encounter knee pain at some point in their lives. If your knee pain is chronic in nature, then it may last for a prolonged period.

a) Fractures may cause you to feel pain in the areas of your knee bones.
b) Anterior Cruciate Ligament injury (ligament injury caused by twisting and a sudden motion) or Medial Collateral Ligament injury (injury to the tissue in the insides of your knee) is very common to sportspersons and may be the reason for severe knee pain.
c) Sometimes your knee bones may get dislocated from their usual alignment. This can also make you experience severe knee pain.

Suffering from Knee Pain - Know What Causes it? 

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

Knee replacement can be extremely painful. Previously, opioids or narcotics were administered for pain relief. But excessive addition of opioids is not exactly effective for controlling pain. 

Multimodal pain management has become an important part of the perioperative care of patients undergoing total joint replacement. The principle of multimodal therapy is to use interventions that target several different steps of the pain pathway, allowing more effective pain control with fewer side effects. Many different protocols have shown clinical benefit. The goal of this review is to provide a concise overview of the principles and results of multimodal pain management regimens as a practical guide for the management of joint arthroplasty patients.

Multimodal denotes administering two or more than two types of medications that work with different mechanisms. The following are the techniques used:

Pre-operative Femoral Nerve Block: Prior to the surgery, a catheter is placed beside the femoral nerve for blocking it. This nerve is located in the upper thigh. Medication is delivered through the catheter for the nerve to be numbed for 24 hours. Thus, pain signals to the brain are blocked. This method reduces the use of narcotics and the consequent side effects.

Patient Controlled Analgesia (PCA): This method is also known as  Pain Pump . An intravenous pump is used to administer pain relief medications, such as oxymorphone or morphine, after the surgery. The control button of the machine could be pressed, by the patient for 6 to 10 times per hour. The machine is used for two post-operative days.

Oral Medications: The oral medications include Non-Steroidal Anti-Inflammatory drugs or NSAID; such as Celebrex which is similar to aspirin, structurally. Alternatively, acetaminophen, such as Tylenol or its equivalent composition, can also be used.

Acetaminophen: It acts on the Central Prostaglandin Synthesis and relieves the patient of pain through multiple mechanisms.

Epidural Analgesia: It produces lower pain scores and involves less time for achieving physical therapy goals. However, this is subject to side effects such as dizziness, urinary retention and itchiness.

Gabapentinoids: These medications include membrane stabilizers such as Gabapentin and Pregabalin.

The objective of multimodal treatments is to provide quick relief to the patient and immediately so. Earlier the rehabilitation, more successful will be the knee replacement surgery.

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.
