Hip Osteoarthritis

Hip arthritis classically hurts in the groin, not the side of the hip — knowing the difference changes the whole plan.

What it is

Osteoarthritis of the hip wears the cartilage of the ball-and-socket joint. True hip-joint pain lives in the groin and deep buttock and shows itself when you put on socks, get out of a car, or walk farther than the joint wants. Pain over the outer hip is usually something else — commonly tendon or bursa — and pain down the leg may be the spine borrowing the hip's name.

Symptoms

  • Groin or deep buttock pain with weight-bearing activity
  • Stiffness — trouble reaching the foot to dress, less hip rotation
  • A limp or shortened stride at the end of long days
  • Night ache in later stages

How we evaluate it

Exam maneuvers that load and rotate the joint, standing X-rays, and — when the source is genuinely uncertain — a diagnostic image-guided injection into the joint: if numbing the hip removes the pain, the hip is the answer. That single test regularly saves patients from treating the wrong body part.

Red flags — don't wait on these

  • Inability to bear weight, especially after a fall (possible fracture)
  • Fever with a hot, irritable hip
  • Night pain that is constant and unrelenting
  • A history of cancer with new, unexplained hip pain

If any of these apply, go to an emergency department or call 911 rather than waiting for a clinic appointment.

Conservative care first

Strengthening around the hip, activity modification that keeps you moving, weight management, and simple analgesics carry many people comfortably for years. Arthritis on an X-ray is a fact; what you do about it depends on how it treats you.

Procedures that may be considered

Image-guided intra-articular injections — corticosteroid for flares, and in selected patients orthobiologic options such as PRP or BMAC, which remain investigational for hip arthritis — can be part of a plan built around your goals, with evidence and costs discussed plainly. The hip is a deep joint; guidance isn't optional here.

When surgery makes sense

Hip replacement is one of the most successful operations in existence. When groin pain limits your life despite real conservative effort and X-rays agree, we'll tell you clearly that you've earned the operation — and refer you to a surgeon we'd send family to.
