Knee Pain vs Arthritis: How to Tell the Difference

Knee pain is a common condition that can affect people of all ages. However, not all knee pain is caused by arthritis. Understanding the difference between general knee pain and arthritis can help you determine when to seek medical care.


At MD Spine Care & Orthopaedics in San Antonio, we evaluate knee conditions to identify the underlying cause and recommend the most appropriate treatment options.

What Is General Knee Pain?

Knee pain is a broad term that can result from a variety of causes, including:


  • Injuries (ligament tears, meniscus tears)
  • Overuse or repetitive strain
  • Tendonitis
  • Muscle imbalances


This type of pain may develop suddenly or gradually and is often related to activity.


What Is Arthritis in the Knee?

Arthritis is a degenerative condition that affects the joint over time. The most common type is osteoarthritis, which occurs when cartilage gradually wears down.


This leads to:

  • Joint inflammation
  • Stiffness
  • Reduced mobility
  • Chronic pain

How Knee Conditions Are Diagnosed

Diagnosis typically includes:


  • Medical history review
  • Physical examination

  • Imaging such as X-rays or MRI


This helps determine whether the pain is caused by arthritis, injury, or another condition.
