Understanding Osteoarthritis (OA)

What OA is, why it progresses, and how image-guided, non-surgical care helps you stay active.

Reading time: ~6 min Non-Surgical Image-Guided

Overview

Osteoarthritis is the most common arthritis. As cartilage thins and joint fluid loses its “slippery” quality, movement becomes painful and stiff—especially in weight-bearing joints like the knees and hips. Without targeted care, OA tends to progress over time.

Why OA Gets Worse

Healthy joints have smooth cartilage and a thick gel (synovial fluid) that cushions and lubricates. In OA, the gel degrades and cartilage wears, increasing friction, inflammation, and that “bone-on-bone” feeling people describe.

Think of OA like an engine with old oil: friction builds, parts wear, and performance drops. Replace the “oil,” reduce friction, and function often improves.

Common Signs & Symptoms

  • Stiffness after rest; pain with walking, stairs, or squatting
  • Grinding, clicking, or swelling around the joint
  • Night pain that disrupts sleep and recovery

Evaluation at NYC Pain MD

Your visit typically includes a detailed history, focused exam, and weight-bearing X-ray to grade OA severity. From there, we map an image-guided plan tailored to your goals.

Key Takeaways

OA is progressive, but targeted, image-guided, non-surgical care can reduce pain, restore motion, and delay or avoid surgery.
