Most can be treated conservatively, but surgical reconstruction is required if conservative treatment fails. Modified Brostr\u00f6m\u2013Gould procedure is an effective surgical treatment and the augmentation of this procedure with a periosteal flap may confer additional stability. We report on the outcome of a technique combining a modified Brostr\u00f6m\u2013Gould procedure augmented with a periosteal flap in patients with chronic lateral ankle instability.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Method:<\/jats:title>\n                    <jats:p>Twenty-four males aged 18\u201342 (mean, 24) with chronic lateral ankle instability affecting 24 ankles underwent the modified Brostr\u00f6m\u2013Gould procedure augmented with a periosteal flap, and these surgeries were performed by a single surgeon. The mean follow-up period was 28.7 months.

Patients with poor quality local ligamentous tissue, obese patients or high demand athletes generally benefit from this procedure.
