Knee Arthritis

What is Knee Arthritis?

Knee arthritis, also known as osteoarthritis of the knee, is a degenerative joint disease characterized by the progressive breakdown of the protective cartilage that cushions the knee joints. As the cartilage deteriorates, the bones in the knee joint begin to rub against each other, leading to pain, stiffness, and inflammation. Knee arthritis often develops gradually over time and is more prevalent in older adults, although it can affect individuals of all ages.

Causes

Several factors contribute to the development of knee arthritis. The primary causes include:

• Aging: As we age, the cartilage in our joints naturally undergoes wear and tear, increasing the risk of developing arthritis.
• Joint Injuries: Past injuries, such as fractures, ligament tears, or meniscus tears, can disrupt the normal functioning of the knee joint, leading to an increased likelihood of arthritis.
• Obesity: Excess weight places additional stress on the knee joints, accelerating cartilage degeneration and increasing the chances of developing arthritis.
• Genetics: Certain genetic factors can make individuals more susceptible to developing knee arthritis.

Symptoms

The symptoms of knee arthritis can vary from person to person, but commonly include:

• Pain: Persistent knee pain, especially during weight-bearing activities such as walking or climbing stairs, is a hallmark symptom of knee arthritis.
• Stiffness: The affected knee may feel stiff and inflexible, particularly after periods of inactivity or prolonged sitting.
• Swelling: Inflammation within the knee joint can cause swelling, resulting in a noticeable increase in knee size.
• Limited Range of Motion: Knee arthritis can restrict the full range of motion, making it difficult to fully extend or bend the knee.
