Early Signs and Symptoms of Knee Osteoarthritis: What You Need to Know

What are the symptoms of knee osteoarthritis?
Knee osteoarthritis (OA) is a degenerative joint condition where the protective cartilage in your knee wears down over time. Common symptoms include:

• Pain that worsens with activity
• Stiffness, especially in the morning or after sitting
• Swelling around the knee
• Grinding or popping sounds
• Reduced range of motion
• A feeling of instability or weakness

Why does my knee click or pop?
Knee clicking or popping (called “crepitus”) is often caused by cartilage wear, meniscus tears, or joint fluid movement. Occasional painless clicking can be normal, but persistent or painful sounds may suggest underlying arthritis or joint damage.

Why is my knee swollen?
Swelling can result from inflammation or excess fluid in the joint. In osteoarthritis, cartilage damage triggers inflammation in the joint lining (synovium), leading to fluctuating swelling that may get worse with activity.

What is a Baker’s cyst?
A Baker’s cyst is a fluid-filled swelling behind the knee caused by joint fluid buildup. It often develops in response to knee osteoarthritis or meniscal injuries and can lead to tightness, stiffness, and discomfort behind the knee.

What are the early signs of knee osteoarthritis?
Early signs may be subtle and include:

• Mild pain during or after activity
• Joint stiffness, especially in the morning
• Difficulty climbing stairs or squatting
• A sense of tightness in the knee
• Mild swelling that comes and goes

Could my pain be from osteoarthritis?
If your knee pain builds up gradually, worsens with use, and improves with rest—combined with swelling, stiffness, or noises in the joint—osteoarthritis could be the cause. Our clinic offers affordable same-day X-rays and MRI scans to confirm your diagnosis and plan a safe, non-invasive treatment.
