Which statement best describes the typical clinical presentation of hip osteoarthritis?

• A. Pain in the ankle with preserved hip motion
• B. Pain in the groin, thigh, or knee with restricted range of motion
• C. Sharp shoulder pain with normal hip function
• D. Night pain only with no daytime movement limitation

Answer: (B)

Hip osteoarthritis typically causes a deep, ache-pain in the groin region that can radiate to the anterior thigh or knee, and it is usually accompanied by a progressive loss of hip motion, especially internal rotation. This combination—groin/thigh/knee pain with restricted range of motion during activity—fits the classic mechanical pattern of hip OA, where pain worsens with weight-bearing and improves with rest, and patients develop a noticeable reduction in hip flexibility over time.

Other patterns don’t fit as well: ankle pain with preserved hip motion suggests an issue localized to the ankle rather than the hip joint; sharp shoulder pain with normal hip function points to shoulder pathology; and night pain only with no daytime movement limitation is less typical for hip OA, which generally involves daytime activity-related symptoms and functional limitation.

So the statement describing pain in the groin, thigh, or knee with restricted range of motion best reflects the typical presentation of hip osteoarthritis.
