Osgood-Schlatter disease is not rare, and it usually heals with conservative therapy. But some cases do not respond to conservative treatment. We call them So-Called Unresolved Osgood-Schlatter disease. 6 patients (7 knees) of So-Called Unresolved Osgood-Schlatter disease underwent surgical procedures to relieve their symptoms of three years duration. 6 patients (7 knees) had a distinct and separate fragment at the proximal aspect of the tibial tubercle. Resection of the fragment along with the adjacent bursa relieved its symptoms. Microscopic findings showed that all fragments were necrotic and were separated from the tubercle by a bursa or scar tissue. The symptoms were relieved after the surgery. Removal of the fragments is indicated in case of So-Called Unresolved Osgood-Schlatter disease.
