When is physiotherapy recommended for osteochondritis dissecans?

Osteochondritis dissecans affects a section of bone and cartilage near a joint, often the knee. The treatment plan depends on age, symptoms, lesion stability, and whether a loose fragment is present. Physiotherapy may be introduced during protected weight-bearing or activity restriction, or after symptoms settle, to preserve safe range of motion and maintain strength without overloading the area. It should complement, not replace, the orthopaedic plan.

Use the walking, sport, and weight-bearing limits given by your clinician. Do not add impact exercise, jumping, or deep loaded bending simply because discomfort has eased. A physiotherapist can teach suitable exercises for the hip, thigh, and trunk, then progress control and function as healing allows. Bring imaging reports and mention locking, catching, swelling, or pain during rest so the programme reflects the joint’s status.

Contact an orthopaedic clinician promptly if the joint locks, repeatedly gives way, swells suddenly, or you cannot bear weight. Urgent assessment is appropriate after a major injury or when severe pain is accompanied by a visibly deformed joint.

Ask whether the lesion appears stable, which movements are restricted, when physiotherapy can begin, and what signs should pause the exercise plan.
