INTRODUCTION TO THE KNEE DISORDERS

When there are some imbalances within the knee then it can lead to disorders which can be indicated by deviation of the knee in terms of function. Most of these disorders occur due to some conditions imposed onto the structures present inside the knee.

BURSITIS: – inflammation (burning sensation) of the bursa causes pain.

(TIP- a word ending with itis refers to inflammation)

FAT PAD IMPINGEMENT: – the fat pad gets swollen heavily and can burst due to over-expansion.

TENDINITIS: – inflammation of a tendon

TORN MENISCUS: – a sudden twist of the knee can tear the rubbery cartilage leading to serious issues.

FRACTURE: – the bones surrounding the joint may get broken especially the patella is viable to damage in the case of accidents.

DISLOCATION: – the knee bone slips and comes out from its original location leading to excruciating pain.

ACL AND PCL INJURY: – the anterior and posterior cruciate ligament gets torn which may occur when there are a lot of instantaneous turns. However, this occurs rarely since these are very strong ligaments naturally. 

OSGOOD-SCHLATTER DISEASE: – this is the swelling of the tendon between the tibia and patellar muscles.

STRAIN AND SPRAIN: – both are injuries but strain occurs in ligaments whereas sprain occurs in tendons.

These are some of the common disorders occurring to the knee. All of these disorders have something in common….PAIN but the intensity can vary based on time and severity of the disorder

ARTHRITIS                                                      

Arthritis is a commonly used word referring to the inflammation of joints. In fact, many people have an intuition that severe pain in the knee corresponds to arthritis mainly in old age groups. This is potentially a dreadful disease and can mainly affect the old aged. Most arthritis occurs over time but some can occur suddenly. Old-aged persons are more prone to this disease. This disease is likely to affect all age groups. This disease is more prevalent in women rather than men since their joints are weaker and more susceptible to motion when compared to men.

differences between normal and arthritic knee joint

  

In the case of arthritis, the bones start to wear down, the ligaments can tear, inflammation and swelling can occur, and also lead to internal bleeding (hematoma). There are about 100+ types of arthritis with different causes and symptoms.

The different types of arthritis have symptoms different from each other. But arthritis, in general, shows some symptoms irrespective of the type.

Joint pain, stiffness in joints, red swollen mass, deranged and irregular motion is some of the common symptoms exhibited during arthritis. These symptoms are easy to identify by a common man and hence one can consult a medical practitioner known as a rheumatologist. The study of joints is known as arthrology and it is recommended to consult such a person.

As mentioned earlier cartilage is the one that protects the bones and also acts as a shock absorber. In the case of Osteoarthritis, this cartilage starts to vanish slowly. In the case of rheumatoid arthritis, the synovial fluid gets attacked by its own antibodies!!! This phenomenon in medicine is known as autoimmune disease and occurs due to error in the programming of these cells leading to the attack on their own cells.

In the case of gouty arthritis, there is a deposition of sodium urate crystals in the joints. It can lead to redness, pain, and heat around the joint. Uric acid which is generated in our body gets converted to purines (an essential component in DNA). Increased uric acid levels can lead to its deposition in the form of crystals. The best way is to remove the synovial fluid.

So these are the different types of disorders that can be seen in the knee. Proper diet and exercise and a healthy lifestyle can prevent most of them. So it is essential to be healthy to prevent the occurrence of these diseases.
