Knee Osteoarthritis: When Wear and Tear Becomes Painful

Knee osteoarthritis is a common joint condition that causes pain and stiffness in the knee. It's often referred to as "wear and tear" arthritis because it results from the breakdown of cartilage, the smooth, rubbery tissue that cushions the bones within your knee joint.

What Happens in Knee Osteoarthritis?

Healthy cartilage acts like a shock absorber allowing your knee to move smoothly. In knee Osteoarthritis this cartilage progressively thins and wears away. As this happens, the bones underlying the cartilage start rubbing together, causing pain, inflammation, and stiffness. Bone spurs, small bony growths, can also develop around the joint.

Symptoms of Knee Osteoarthritis:

  • Pain: This is usually the most prominent symptom, often worsening with activity and improving with rest. You might feel pain around the knee, or a deep aching within the joint.

  • Stiffness: The knee may feel stiff, particularly in the mornings or after periods of inactivity.

  • Swelling: Some people with knee OA experience swelling around the knee joint. Here are the things you can avoid if you have already had knee replacement surgery.

  • Reduced mobility: The knee's range of motion may become limited, making activities like bending down or climbing stairs difficult.

  • Grating or cracking sounds: You might hear a grinding or crackling sensation when you move your knee.

What Causes Knee Osteoarthritis?

There isn't a single cause of knee OA, but several factors contribute to its development:

  • Age: It's more common in older adults, as cartilage naturally breaks down with age.

  • Weight: Carrying excess weight puts extra stress on the knee joint, accelerating cartilage wear and tear.

  • Previous knee injury: Injuries like ligament tears or meniscus damage can increase the risk of OA.

  • Repetitive stress activities: Jobs or hobbies that involve repetitive kneeling, squatting, or heavy lifting can contribute to knee OA.

  • Family history: Having a close relative with knee OA increases your risk.

Treatment Options for Knee Osteoarthritis:

While there's no cure for knee OA, there are effective treatments to manage symptoms and improve your quality of life. These include:

  • Nonsteroidal anti-inflammatory drugs (NSAIDs): These medications help reduce pain and inflammation.

  • Physical therapy: Exercises to strengthen the muscles around the knee and improve flexibility can significantly improve function.

  • Weight management: Losing weight can significantly reduce stress on the knee joint and improve symptoms.

  • Joint injections: Cortisone injections can provide temporary pain relief.

  • Assistive devices: Using a cane or knee brace can help take pressure off the joint.

  • Surgery: In severe cases, joint replacement surgery may be an option.

Living with Knee Osteoarthritis:

Knee Osteoarthritis can be a challenge, but with proper management, most people can lead active lives. If you're experiencing knee pain, consult your doctor for a diagnosis and discuss treatment options. Early intervention can help slow the progression of the disease and maintain a good quality of life.
