Among these, 25 patients underwent initial closed reductions, and 85 patients underwent an open reduction directly. Watson\u2010Jones anterolateral approach was used during the surgery for injury to the retinaculum of Weitbrecht, and FHN was assessed as a surgical outcome. The severity of injury to the retinaculum of Weitbrecht was evaluated using a scoring system developed by our surgical team.

Twenty\u2010six patients experienced FHN postoperatively, with mean onset time of 19.42\u2009\u00b1\u20093.87\u00a0months.
