Knee pain can significantly limit mobility and quality of life. Osteoarthritis, a common condition affecting millions, is a major culprit. As the protective cartilage in the knee deteriorates, it can lead to persistent pain, swelling, and reduced function.

What is Knee Pain?

Knee pain refers to discomfort or aching in or around the knee joint. It may arise from acute injuries, chronic conditions, or underlying diseases like osteoarthritis. Depending on the cause, knee pain can range from mild and intermittent to severe and constant, interfering with daily activities.

Common Causes of Knee Pain

• Injuries: Ligament tears, fractures, or dislocations.
• Inflammatory Conditions: Rheumatoid arthritis or gout.
• Overuse: Tendinitis or repetitive strain from activities like running.

Degenerative Diseases: Osteoarthritis is the leading cause of chronic knee pain.

How Osteoarthritis Contributes to Knee Pain

Osteoarthritis (OA) is often referred to as a “wear-and-tear” disease, affecting the cartilage that cushions the bones in the knee joint. As the cartilage wears away, the bones rub against each other, triggering pain and inflammation. This process transforms the knee from a well-functioning joint into a source of persistent discomfort.

Key Ways Osteoarthritis Causes Knee Pain

Osteoarthritis can cause knee pain through several ways including:

Cartilage Loss
Cartilage loss removes the smooth, cushioning surface between bones, causing them to rub together, leading to pain, inflammation, and stiffness. 

Inflammation
Osteoarthritis is often accompanied by inflammation in the joint. Swelling puts additional pressure on the knee, intensifying pain.

Bone Spurs
As the body attempts to repair damaged cartilage, it forms bony growths called osteophytes or bone spurs. These spurs irritate surrounding tissues like tendons, ligaments, or nerves, contributing to stiffness and discomfort.

Joint Space Narrowing
Joint space narrowing occurs when cartilage between the bones in the knee joint wears down, causing bones to come closer together. This can lead to pain and reduced range of motion as the bones rub against each other. 

Muscle Weakness
Pain from joint conditions like osteoarthritis discourages movement, leading to muscle weakening around the knee. This creates a vicious cycle where weak muscles fail to support the joint, worsening pain.

Types of Chronic Knee Pain 

Chronic knee pain can be described in various ways, depending on the stage and severity of the underlying condition:

• Aching Pain: Persistent and dull, worsening after physical activity.
• Sharp Pain: Sudden, intense pain during movement or joint loading.
• Night Pain: Discomfort that disrupts sleep, often due to inflammation.

Weather-Related Pain: Increased sensitivity to cold or humid conditions.

Impact of Knee Pain on Daily Life

Chronic knee pain or pain associated with osteoarthritis can severely limit everyday activities, such as walking, climbing stairs, or even standing for extended periods. Over time, the condition affects not only physical health but also emotional well-being as individuals cope with reduced mobility and independence.
