Osteoarthritis (OA) is one of the most wide spread types ofarthritis and is found most often to stast developing after the ageof 45. I may also form as the result of a jury to a joint. Men andwomen are affected equally by this condition.AO causes thebreakdown of the cartilage between the joints. Cartilage is thematerial that covers the end of the bone at the joints to ensuresmooth and effortless movement. In OA, this cartilage breaksdown.OA usually occurs in the fingers and weight-bearing joints;these include, knees, feet, hips and back.
Osteoarthritis is the result of changes in the cells of thecartilage resulting in a loss of elasticity. Over time this causesthe cartilage to thin out and in some situation breakdown alltogether. This leaves the ends of the bone without its smoothcovering, and the joint loses its easy mobility..
OA progresses slowly. For many people the symptoms will be mild andhave little impact. OA rarely causes severe disability, but when itdoes surgery to replace joints is often highly effective.
Symptoms of OA vary. Most individuals remain essentially free ofsymptoms until the cartilage ceases to function properly. Afterthat they may include, Pain, Swelling, and stiffness in theaffected joint or joints.
To diagnose RA Your doctor will first assess your situation bychecking the affected joints for outward signs of inflammation heatetc. then if he deems it necessary may order tests such as X-rayand blood tests joint fluid tests to exclude the possibility ofother types of arthritis.The management of this condition dependson the joints affected and the physique of the patient. Andincludes, Exercise, Education, Medication, Joint protection, andHealthy weight maintenance
Answer also: “Osteoarthritis”, states the Western Journal ofMedicine, “is in many ways like the weather, ubiquitous, oftenunnoticed, sometimes dramatic in its effects. OA concentrates itserosive influence in one or just a few joints. As cartilage isslowly eroded, bone begins to grinding against bone. This isaccompanied by an outgrowths caused osteophytes. Cysts may form,and the underlying bone thickens and become deformed. Othersymptoms include knobby knuckles, grating and grinding sounds thatemanate from arthritic joints, and muscle spasms, along with pain,stiffness and loss of mobility. The American Journal of Medicinestates: There is no evidence that a normal joint, subject to commonstresses, will break down over the life of a person. Efforts tounderstand the exact cause of OA are “plagued by controversy”according to the British magazine The Lancet.
Some investigators propose that damage to a bone, such asmicro-fractures may occur first. This, in turn may trigger bonyoutgrowths and cartilage deterioration. Others think that OA startsin the cartilage itself. As it degenerates and frays, they reason,stress increases on the underlying bone. Pathological changes occuras the body attempts to repair the damaged cartilage. While age doenot cause OA, the loss of joint cartilage experienced morefrequently with increasing age. Other risks may include those whohave an abnormality in the way their joint surfaces fit together orwho have weak leg and thigh muscles, legs of unequal length, or amisalignment of the spine. Trauma to a joint caused by an accidentor by an occupation in which repetitive motions overuse a joint canalso set the stage for osteoarthritis. Once deterioration begins,being overweight can exacerbate OA.
