Comprehensive Analysis of Minimally Invasive Management for Persistent Anterolateral Ankle Pain: A Systematic Review.

Abstract

Persistent anterolateral ankle pain is a debilitating condition often associated with soft tissue impingement following inversion injuries. It can lead to significant limitations in daily activities and overall quality of life, particularly in individuals with chronic ankle instability. This systematic review examines the efficacy and safety of minimally invasive arthroscopic decompression techniques in managing anterolateral ankle impingement syndrome. A total of 246 cases from nine studies were reviewed, involving 135 males with a mean age of 29.6 years and an average follow-up period of 29.5 months (range: 15-83.7 months). Outcomes were assessed using the American Orthopaedic Foot and Ankle Society (AOFAS) scores and Meislen criteria. The AOFAS scores improved significantly from a mean of 40.75 preoperatively to 84.2 postoperatively, reflecting substantial functional recovery. Based on the Meislen criteria, 124 cases (50%) were rated as excellent, 71 (29%) as good, 14 (6%) as fair, and three (1%) as poor. Postoperative mobility was restored to normal in 130 cases, with complications reported in 24 cases (9.8%), including hypoesthesia, infections, intra-articular haemarthrosis, scar tissue formation, nerve irritation, and persistent pain or numbness. Patient satisfaction was high, with most patients reporting significant improvements in pain relief and functional capacity. Arthroscopic decompression is a safe, minimally invasive, and effective intervention for managing persistent anterolateral ankle impingement, offering substantial improvements in pain, mobility, and overall function with low morbidity and a manageable complication rate. This approach is an invaluable option for patients unresponsive to conservative treatments.
