How long does cartilage repair surgery take to work for osteochondritis dissecans?

Osteochondritis dissecans can affect the bone and cartilage at a joint surface. Surgery may secure, stimulate, or replace the affected area, depending on whether the fragment is stable, the lesion is mature, and the tissue can heal. The knee may feel less painful while the underlying repair still needs protection.

Your pace is shaped by the lesion’s location and size, skeletal maturity, the operation performed, alignment, associated procedures, and the knee examination. Clinicians look for controlled swelling, full or improving movement, stable walking, and restored strength before allowing impact.

Follow instructions about crutches, brace use, weight-bearing, and bending. Complete the prescribed rehabilitation in sequence: regain safe motion, activate the thigh muscles, build strength, and then retrain balance and movement. Avoid deep squats, jumping, and cutting sports until the surgical team clears them.

A flare after exercise is useful information, not a signal to push harder. Tell your therapist about swelling, catching, locking, or pain that lasts into the next day so the programme can be adjusted.

Contact the surgical team for fever, wound drainage, increasing redness, severe swelling, new calf pain, or worsening pain. Urgent assessment is needed for chest pain or sudden breathlessness. Report a locked knee, repeated giving way, or a new injury during recovery promptly.

Ask whether the lesion was fixed, stimulated, or reconstructed; how loading will advance; which symptoms are expected; and what examination or imaging will determine readiness for sport or demanding work.
