- Arthritis Of Knee
Arthritis of the knee is a common condition that occurs when the cartilage in the knee joint gradually wears down. Cartilage acts as a protective cushion between the bones, allowing the joint to move smoothly. When this cartilage deteriorates, the bones may rub against each other, causing pain, swelling, and stiffness.
Many people experience knee arthritis as they age, although the condition can also develop due to injuries, repetitive stress, or inflammatory diseases. Over time, knee joint arthritis can make everyday activities such as walking, climbing stairs, or standing for long periods more difficult.
Understanding the symptoms of arthritis in the knee, its causes, and available treatment options can help individuals manage the condition and maintain joint mobility.
What Is Arthritis of the Knee?
The knee is one of the largest and most complex joints in the body. It is formed by the connection of the thigh bone (femur), shinbone (tibia), and kneecap (patella). The ends of these bones are covered with cartilage, which allows the joint to move smoothly and absorb shock during movement.
Arthritis of the knee occurs when this cartilage becomes damaged or worn away. As cartilage deteriorates, the joint may become inflamed, leading to knee joint inflammation and discomfort.
Over time, this condition may cause knee joint pain, stiffness, and limited mobility. In severe cases, bones may begin to rub directly against each other, leading to significant joint damage.
Symptoms of Arthritis in the Knee
Recognizing the symptoms of arthritis in the knee early can help prevent further joint damage and improve treatment outcomes.
Common Arthritis Symptoms in the Knee
- Persistent knee joint pain
- Swelling around the knee joint
- Stiffness, especially after periods of rest
- Reduced range of motion
- Grinding or clicking sensations in the knee
- Difficulty bending or straightening the knee
These arthritis symptoms knee may worsen during activities such as walking, climbing stairs, or standing for extended periods.
Many people also experience increased discomfort in the morning or after sitting for long periods.
Causes of Knee Arthritis
There are several factors that can contribute to the development of arthritis of the knee.
Age and Cartilage Wear
As people age, the cartilage in the joints naturally begins to deteriorate. This is one of the most common causes of osteoarthritis of the knee.
Previous Knee Injuries
Past injuries such as ligament tears, fractures, or meniscus injuries can increase the risk of developing knee joint arthritis later in life.
Repetitive Stress on the Knee
Occupations or activities that involve repeated knee bending, heavy lifting, or high-impact movements can accelerate cartilage damage.
Excess Body Weight
Carrying extra body weight places additional stress on the knee joint, increasing the likelihood of knee arthritis.
Genetic Factors
Some individuals may be genetically predisposed to developing arthritis in their joints.
