Bone union of painful bipartite patella after treatment with low-intensity pulsed ultrasound: report of two cases.
We report two cases of painful bipartite patella in which bone union was achieved after treatment with low-intensity pulsed ultrasound. Both patients were 13-year-old males. Each received ultrasound (SAFHS, EXOGEN) for 20 min a day. The interval between the onset of pain and ultrasound treatment was between 2 and 4 months. The patellar pain disappeared within two months after treatment in both cases. Bone union was seen radiographically at 4 months. Low-intensity pulsed ultrasound is a non-invasive treatment that appeared to be helpful in the management of two patients with painful bipartite patella.
