• Knee pain (may be the only symptom, initially)
• Persistent thigh or groin pain
• Atrophy (wasting) of muscles in the upper thigh
• Slight shortening of the leg, or legs of unequal length
• Hip stiffness restricting movement in the hip
• Difficulty walking, walking with a limp (which is often painless)
• Limited range of motion

During a physical examination, the doctor will look for a loss in hip motion. A hip X-ray or pelvis X-ray may show signs of Legg-Calve-Perthes disease.
