Abstract
BACKGROUND:
Soft-tissue impingement syndrome is now increasingly being recognized as a significant cause of chronic ankle pain. The aim of this study was to investigate the diagnostic accuracy of contrast-enhanced, fat-suppressed, three-dimensional (3D), fast-gradient-recalled acquisition in the steady state with radio-frequency-spoiling (CE 3D-FSPGR) magnetic resonance imaging (MRI), and to evaluate the clinical outcome of arthroscopic treatment of soft-tissue impingement associated with the ankle trauma.
METHODS:
This study reviewed 38 patients who had preoperative MRI and arthroscopic treatment of chronic ankle pain after trauma. The CE 3D-FSPGR MRI was used to evaluate the chronic ankle pain, and the American Orthopedic Foot and Ankle Society (AOFAS) Ankle-Hindfoot Score was used to evaluate the clinical results after arthroscopic treatment.
RESULTS:
The CE 3D-FSPGR MRI showed a sensitivity of 91.9%, a specificity of 84.4%, and an accuracy of 87.5% in diagnosing synovitis and soft tissue impingement. All patients had excellent or good outcomes after arthroscopic debridement.
CONCLUSION:
The results of this study suggest that a preoperative fat-suppressed CE 3D-FSPGR MRI is highly beneficial in diagnosing synovitis and soft-tissue impingement and that arthroscopic debridement of the synovitis or soft-tissue impingement has a good clinical outcome.
