Trattamento artroscopico di una osteocondrite dissecante della troclea femorale

The juvenile osteochondritis dissecans of femoral trochlea is an uncommon lesion. Review of the literature reveals few reported cases of the medial or lateral trochlea. We report on 11-year-old child with a complete separate trochlea fragment. MRI and arthroscopy have shown a 2,5 × 2,2 cm osteochondral lesion. The fragment was reduced and synthesised by 3 absorbable pins using arthroscopic approach. At 6 months follow-up, the patient did not complain of knee pain, had full range of motion and returned to all the activities performed before the traumatic event. MRI and Athro-MRI showed healing of the lesion and continuity of the articular surface without any cleft between the fragment and the surrounding cartilage.
