Comparison of Radiologic Parameters between Weight Bearing Affected Single Ankle Anteroposterior View and both Ankle Anteroposterior View in Ankle Osteoarthritis

Purpose: This study was performed to analyze the results of radiologic parameters between weight bearing affected single ankle anteroposterior (AP) view and both ankle AP view in ankle osteoarthritis (OA). Materials and Methods: Between January 2009 and August 2010, 41 patients (50 ankles) who visited our institution to treat ankle OA were reviewed retrospectively. In radiographic assessment, weight bearing affected single ankle AP view and both ankle AP view were checked, and measured tibial anterior surface angle (TAS), tibial medial malleolar angle (TMM), talar tilting angle (TT), maximum and minimun joint space width (JSW) of ankle, width between articular surface of medial malleolar and medial articular surface of talus as radiologic parameters. Results: On weight bearing both ankle AP view, TAS was $85.4{\pm}4.1^{\circ}$, TMM was $33.1{\pm}9^{\circ}$, TT was $5.4{\pm}6.1^{\circ}$, maximum JSW was $3.2{\pm}2.7$ mm, minimum JSW was $1.1{\pm}1.3$ mm, width between articular surface of medial malleolar and medial articular surface of talus was $1.8{\pm}1.8$ mm and on weight bearing affected ankle AP view, TAS was $85.3{\pm}3.9^{\circ}$, TMM was $34.3{\pm}10.9^{\circ}$, TT was $5.4{\pm}6.5^{\circ}$, maximum JSW was $3.2{\pm}2.7$ mm, minimum JSW was $1.1{\pm}1.3$ mm, width between articular surface of medial malleolar and medial articular surface of talus was $1.6{\pm}1.7$ mm. Conclusion: There is no statistical significance in radiologic parameters between weight-bearing affected single ankle AP view and both ankle AP view in ankle OA.
