Osteoarthritis is the progressive destruction of joint cartilage and formation of extra bone on the edges of joint. With time the joint becomes painful and stiff due to increased friction within the joint. Osteoarthritis is the most common form of arthritis. Ageing is strongly related to osteoarthritis but many other factors can be associated with this disease. Some of the causes are listed below.
If the joints are loaded with more amount of weight than it can bear, it leads to more friction within the joint which hastens the wear and tear process. It is important to reduce weight if there is a threat of osteoarthritis. Also losing weight can improve pain in weight-bearing joints.
Trauma to the joint surface can make its movement rough that increases friction. Early osteoporosis can be observed in people with joint surface trauma such as fractures or recurrent ligament injury. It is important to consult your orthopaedic doctor in such cases.
Use of steroids
Excess use of steroids can hasten the degeneration process in joints. Steroids are also known to have changes in the synovial fluid present in joints. Synovial fluid is important to reduce friction in joints and facilitate smooth movements. Reduction or changes in synovial fluid can reduce joint space and cause arthritis.
Deformities in leg such as bow legs and knock knees can cause unequal force distribution in the joint. That leads to tearing down of cartilage wherever more force is applied. This may cause pain in walking and weight bearing. Corrective surgeries are performed in such cases. You can consult your doctor if you have deformed legs and often suffer due to knee pain.
Osteoarthritis is very common these days, especially in the urban population. If you have frequent knee pain, you must consult a specialist bone doctor at the earliest. It will ensure treatment on time and worsening of the situation.
