Arthritis is a general term covering numerous conditions where the joint surface or cartilage wears out. The joint surface is covered by a smooth articular surface that allows pain free movement in the joint. When the articular cartilage wears out the bone ends rub on one another and cause pain. This condition is referred to as Osteoarthritis or "wear and tear" arthritis as it occurs with aging and use. It is the most common type of arthritis.
Common Causes of Arthritis
- Infection of the bone
- Connective tissue disorders
- Inactive Lifestyle
- Inflammation (Rheumatoid arthritis
- weight is the single most important link between diet and arthritis as being overweight puts an additional burden on your hips, knees, ankles and feet.
- Often the exact cause of arthritis is unknown. Osteoarthritis affects people as they get older
Symptoms of knee arthritis include pan and decreased mobility of the knee joint
Knee Arthritis causes pain and decreased mobility of the knee joint. In the arthritic knee, an absent joint space may show on X-ray. The degree of cartilage damage and inflammation varies with the type and stage of arthritis. The capsule of the arthritic knee is swollen. The joint space is narrowed and irregular in outline; this can be seen in an X-ray image. Bone spurs or excessive bone can also build up around the edges of the joint. The arthritic knee is often stiff, and activities may be limited due to pain or fatigue.
There are several procedures available to treat arthritis, including arthroscopy, cartilage grafting and ultimately total knee replacement. The first line of treatment consists of antiinamatories, possible biologics like stem cells, HA viscosupplementation, weight reduction and strengthening with physical therapy. A custom treatment plan will be developed for each patient depending on the severity of the diagnosis. Individuals that benefit from a knee replacement suffer from severe pain or stiffness that hinders daily activity. Pain upon resting is also present as well as inflammation and significant swelling that does not decrease. A decision to get a total knee replacement should only follow a thorough discussion with the surgeon. Recovery from a knee replacement includes significant physical therapy beginning soon after surgery, anti-inflammatory medications, and walking aids such as a walker or crutches.
The knee consists of a fluid called synovial fluid, which reduces friction between the bones of the knee joint when the leg is moving. Sometimes this fluid is produced in excess, resulting in its accumulation in the back of your knee. A Baker's cyst is a fluid-filled swelling that develops into a lump behind the knee. This causes stiffness, tightness, and pain behind your knee. Although it can develop at any age, it is commonly seen in people over age 40.

- rheumatoid arthritis
- an injury to the knee
- or inflammation of the knee joint
When you present with the above symptoms, your doctor will review your medical history and perform a thorough physical examination of your knee. Further tests such as ultrasound scan and MRI may be recommended in order confirm the diagnosis of Baker's cyst.
