What Is the First Treatment for Perthes Disease?

Perthes disease affects the developing ball of a child's hip joint. The hip may become stiff or painful, and the treatment plan is shaped by the child's age, symptoms, hip movement and the stage of the condition. Early management aims to keep the hip moving comfortably and reduce forces that could worsen irritation. Running, jumping and impact sports may need to pause while the hip is assessed.

Keep scheduled orthopaedic reviews because the plan can change as the hip develops. A therapist may teach gentle range-of-motion work and ways to maintain strength without impact. [Paediatric Physiotherapy](/treatments/physiotherapy-and-rehabilitation/paediatric-physiotherapy/) can make exercises age-appropriate and practical at home. Use only the weight-bearing and activity limits provided by the treating team; do not encourage a child to exercise through a limp or escalating pain. In some situations, surgery such as [Osteotomy](/treatments/reconstructive-orthopedic-surgery/osteotomy/) may later be discussed to improve hip positioning, but it is not the automatic first step.

Contact the clinician if the child develops a new limp, increasing groin or thigh pain, reduced hip movement, night discomfort, or difficulty keeping up with ordinary activities. Seek prompt medical attention if the child cannot bear weight, has severe sudden pain, fever with a painful hip, or appears acutely unwell.

Ask which activities are restricted, which hip movements should be practised, how often follow-up imaging is needed, and what changes would make surgery part of the discussion.
