【 摘 要 】

Category:Arthroscopy.Introduction/Purpose:Osteochondral lesions of the tibial plafond (OLTPs) can lead to chronic ankle pain and disability. Arthroscopic treatment has been described after failure of initial nonoperative treatment. However, the ideal appropriate approach for OLTPs is controversial, and it is not known if ankle positioning or joint distraction affects the accessibility of these lesions. The purpose of this study was to determine the effects of predetermined ankle flexion angles on arthroscopic accessibility of the distal tibial articular surface through either the anterior or posterior approach. The effects of non- invasive joint distraction were also analyzed.Methods:Fourteen below-knee cadaver specimens were subjected to pre-operative range of motion measurements. Joint distraction was measured using sizing rods with the precision of 1 mm. The accessible areas at the tibial plafond were marked using a curette at predetermined ankle positions. Arthroscopy was performed using a 30-degree 2...
