Which condition is most commonly treated with hip arthroscopy?

• A. Acetabular fracture
• B. Osteoarthritis of advanced stage
• C. Displaced femoral neck fracture
• D. Femoroacetabular impingement with labral tear

Answer: (D)

Hip arthroscopy is used to address intra-articular hip problems, especially issues with the labrum and cartilage that arise from impingement. In femoroacetabular impingement, abnormal contact between the femoral head and the acetabulum leads to labral tears and cartilage damage. Arthroscopic approaches allow direct access to repair or debride the labrum and to reshape the bone to reduce impingement, which can relieve pain and improve range of motion.

The other scenarios involve conditions that are not typically treated with arthroscopy alone. Acetabular fractures generally require open reduction and internal fixation with larger exposures. A displaced femoral neck fracture is managed with fixation or hip replacement, not arthroscopy. Advanced osteoarthritis is usually addressed with joint replacement, as arthroscopy provides limited long-term benefit in that setting.

So, the condition most commonly treated with hip arthroscopy is femoroacetabular impingement with a labral tear.
