What is the typical presentation of Hip osteoarthritis?

• A. Pain in the shoulder with full hip ROM
• B. Pain in the buttock only with no hip ROM loss
• C. Pain in the groin, thigh, or knee, with restricted range of motion.
• D. Pain only at night, no movement limitation

Answer: (C)

Hip osteoarthritis typically causes deep pain in the hip or groin that can radiate to the anterior thigh or knee, and it is usually worsened by activity. A defining feature is limited hip movement, especially internal rotation and flexion, due to the joint changes from cartilage loss and osteophyte formation. This combination of groin/thigh/knee pain with a restricted range of motion reflects the mechanical nature of hip OA and its impact on joint function.

Pain confined to the buttock with no loss of hip motion is less characteristic because OA generally produces movement limitation. Pain solely at night with no movement limitation doesn't fit the mechanical, activity-related pattern of OA, which tends to be worse with use. Pain in the shoulder with full hip ROM is not related to hip OA, as the hip is not involved.
