Purpose:The purpose of this study is to evaluate the result of arthroscopic excision of painful Os subtibiale and Os subfibulare.
Materials and Methods:Sixteen patients who had accessory bone in the ankle joint were treated by arthroscopy. Os subtibiale was four cases and os subfibulare twelve. The average follow-up period was 9 months range:6~42months). All patients were evaluated clinically with physical examination and radiologically with simple X-ray and for further evaluation, eight with bone scan, three with computed tomography and twelve with magnetic resonance image. We estimated the result of resection with Ogilvie-Harris’s criteria.
Results:All parameters of subjective and functional evaluation were improved with statistical significance(p<0.05). At final evaluation, eight patients still complained of mild pain and among them, three patients for synovitis, three for tendinitis on MRI and two for incomplete resection.
Conclusion:The arthroscopic resection is a very effective method for painful os subtibiale and subfibulare using small incisions and for treatment of associated lesion. The preoperative radiological evaluation is essential and magnetic resornance image is useful for detecting of associated lesion.
