Clinical study on arthroscopy in diagnosis and treatment of anterior ankle impingement syndrome

Objective To explore the clinical value and effect of arthroscopic surgery in the diagnosis and treatment of anterior ankle impingement syndrome. Methods The clinical data of 28 patients who were initially diagnosed as anterior ankle impingement syndrome was reviewed. Arthroscopic surgery was performed in all the patients and the presence of anterior ankle soft tissue impingement or bone impingement was confirmed, and deep cleaning was performed to remove the impact factors. Visual Analogue Scale(VAS)scores and ankle posterior foot scores of American Orthopedic Foot Ankle Society(AOFAS)were compared before and at the last follow-up to evaluate the clinical effects of the patients. Results All patients were successfully followed up, with an average of 2 to 3 years. All patients healed in the first stage of incision, without incision infection. At the last follow-up, the VAS score was(1.50±0.64)points, which was significantly lower than(6.88±0.72)points before operation(P<0.05); the ankle posterior foot score of AOFAS was(90.14±4.04)points, which was significantly higher than(49.16±7.28)points before operation(P<0.05). The excellent and good rate of ankle posterior foot score of AOFAS was 92.00%. Conclusion Arthroscopic technique is of great significance in the diagnosis of anterior ankle impingement syndrome, especially for the anterior ankle soft tissue impingement syndrome. Arthroscopic surgery has less trauma and destruction to the ankle-anatomical structure in the treatment of anterior ankle-impingement syndrome. Meanwhile, it can promote recovery, alleviate pain, and has better clinical effect.
