Understanding Knee Arthritis: Causes and Symptoms

Knee pain can begin gradually or show up suddenly—but when it starts interfering with walking, exercise, or daily routines, it may be a sign of something more serious. Knee arthritis is one of the most common joint conditions affecting adults, especially as they age. At Central PA Physicians Group, with offices in Altoona, State College, Bedford, and surrounding areas, patients receive thorough, compassionate care to help manage symptoms and preserve long-term joint health.

What Is Knee Arthritis?

Arthritis is a condition that causes inflammation in the joints. In the knee, arthritis can lead to pain, stiffness, and reduced mobility. There are several types of arthritis, but the two most commonly affecting the knee are:

• Osteoarthritis (OA): Often referred to as "wear-and-tear" arthritis, OA happens when the cartilage that cushions the bones wears away over time.
• Rheumatoid Arthritis (RA): This autoimmune condition causes the body’s immune system to attack joint tissue, leading to inflammation and joint damage.

Both types can be painful and disabling without proper management.

Common Causes of Knee Arthritis

Several factors can contribute to the development of arthritis in the knee:

• Age: Risk increases significantly after age 50
• Repetitive motion or overuse: Jobs or sports that place stress on the knees
• Previous injuries: Past fractures, ligament tears, or meniscus injuries
• Genetics: A family history of arthritis
• Obesity: Extra weight puts more pressure on knee joints, accelerating joint damage

Understanding the cause is key to finding the right treatment and lifestyle adjustments.

Recognizing the Symptoms

Knee arthritis symptoms can vary but commonly include:

• Joint pain or tenderness, especially after activity
• Stiffness in the morning or after sitting for long periods
• Swelling around the joint
• Decreased range of motion
• A grinding or popping sensation during movement

If left untreated, these symptoms can worsen over time and may limit mobility or independence.
