Reasons And Causes For Knee Pain

Knee pain causes are numerous, the most common among them being arthritis and muscular stress and strain .The former knee pain cause is common in people above 50 years of age   but the latter one is common among all age groups. Other knee pain causes are acute knee injuries, overuse knee injuries, osteoarthritis, rheumatoid arthritis, dislocation of patella (knee bone), damage of tendons or ligaments , fractures in the knee , wearing out of the knee muscles , tendons , ligaments or bones due to its overburdening or because of overwork.

The most common knee pain cause in middle aged people is arthritis. Arthritis is of three types: rheumatoid arthritis, osteoarthritis and gouty arthritis. Rheumatoid arthritis is the most common type of arthritis; it’s an inflammatory disorder that affects the synovial membrane. It affects multiple compartments and causes the joints to swell up which is very painful. Rheumatoid arthritis is caused by inflammation of the synovial membrane which secrets synovial fluid in synovial joints. Because of the inflammation of the synovial membrane, it starts secreting abnormal granular secretions called pannus which deposits on the articular cartilage and leads to its erosion. It is diagnosed by the presence of rheumatoid factor which is a type of immunoglobin, Secondary anaemia and the ESR being high. The second kind of arthritis is osteoarthritis which is a degenerative disorder and it affects the articular cartilage. Gouty arthritis is caused due to excessive uric acid formation or the inability to secrete it. Uric acid gets deposited in synovial joints   and becomes one of the many knee pain causes.

Other knee pain causes are bursitis, dislocation of knee bone, knee sprain or strain and fractures .In bursitis, the bursa of joints becomes inflamed leading to much pain and discomfort. It is caused by either an injury or because of the joint bearing too much of pressure for too long. Dislocation of knee bones is another knee pain cause which is again very common but very painful. It is caused because of displacement of the articular surfaces of a joint which causes damage to nearby ligaments. In most of the cases, the reasons behind dislocation are some injury and excessive pressure or over exertion. Sprains and strains are again one of the major knee pain causes. They are caused when the knee gets twisted without any dislocation of any bone. It leads to damage of nerves, muscles and ligaments which is very painful and usually the pain also makes mobility difficult. It takes time for the damaged tissue to heal back and during the healing time, one needs complete bead rest. It also leads to much swelling of the knee and it’s recommended to wear a knee band in case of sprain. Strain is a somehow diminished version of sprain but nevertheless one of the knee pain causes. In case of stress, less damage is done and it’s less painful as compared to sprain. It also heals back faster and the swelling is also limited.

Another one among the numerous knee pain causes is fractures .Fractures are not so common but very painful and takes a long time to heal back. Other more common knee pain causes are acute knee injuries which includes torn cartilage and ligaments. They are usually caused if a person suddenly stops or turns while running or jumping. Acute knee injuries are common while playing basketball, soccer, volleyball, base ball, tennis, badminton etc. The next in the long list of knee pain causes is overuse knee injuries which include bursitis, tendonitis and muscle strain. Overuse knee injuries are usually caused by overexertion of the knee tissues and bones because of high impact activities alike running, jogging, climbing the stairs, doing high impact aerobics etc.

Knee pain causes mostly result from continuous exertion to the knee without any rest. It’s a scientifically proven fact that while climbing stairs, a person exerts four times the weight of one’s body on ones knees and while running a person’s knees bear up with a pressure equivalent to eight times a person’s normal weight. So it’s important to give one’s knee proper rest once in a while to avoid knee pain and knee pain causes.
