Nano-Arthroscopic Ultrasound-Guided Excision of Unresolved Osgood-Schlatter Disease.

The nano-arthroscopic ultrasound-guided ossicle excision technique is used in the management of an unresolved Osgood-Schlatter disease. The NanoScope is inserted slightly lateral to the proximal patella tendon and moved on between the ossicle and anterior surface of the proximal tibia under ultrasonographic guidance. The 5-mm skin incision is made as a working portal on the medial side of the proximal patella tendon. The proximal border of the ossicle is clearly identified after bursectomy. Then, the ossicles are removed piece by piece using a 2-mm arthroscopic punch. During the resection, the remaining ossicle is continuously confirmed by ultrasound. Finally, the complete excision of the ossicle is shown by the nano-arthroscopic view and ultrasound. The patient is allowed to have a full weight-bearing and an unrestricted range of motion on the day of surgery. Patients are permitted to resume their sports activities without any restriction after 6 weeks. This technique is recommended to athletes who suffer from painful unresolved Osgood-Schlatter disease because of the benefits of it being a minimally invasive surgery with an early postoperative recovery.
