How effective is physiotherapy for osteochondritis dissecans?

Osteochondritis dissecans affects a section of bone and the cartilage covering a joint, often the knee, and can cause pain, swelling or catching. Imaging and an orthopaedic assessment help determine whether the area is stable and whether activity should be restricted. Physiotherapy cannot secure a loose fragment, so the programme must follow that assessment.

When rehabilitation is appropriate, treatment may maintain safe joint movement, preserve strength and gradually restore control. The emphasis can change over time: early care may limit impact and painful loading, while later work may address balance, landing technique and a return to selected activities.

Follow restrictions on running, jumping, twisting or weight-bearing exactly as prescribed. Use the exercises demonstrated, and report swelling, catching or a feeling that the joint is giving way. Do not test progress by suddenly returning to sport; load is usually increased in stages after symptoms and examination support it.

Bring imaging reports and a list of activities that trigger symptoms to appointments. A physiotherapist and orthopaedic clinician can coordinate decisions about supports, exercise progression and whether further treatment is needed.

Seek prompt orthopaedic review if the joint locks, repeatedly gives way, swells after ordinary activity, or pain is worsening despite reduced loading. Urgent assessment is needed if you cannot move the joint or bear weight after an injury.

Do not push through sharp pain or mechanical catching while waiting for review. These symptoms can affect the rehabilitation plan and may require a fresh examination.

Is the lesion stable, and what loading is safe now? Which movements should I avoid? What signs show that rehabilitation is progressing? When can strength or sport-specific drills be added, and what would prompt repeat imaging or specialist review?
