A 21-year-old male with six months of the instability of the ankle presented to our orthopedic department. He reported a trauma history in the ankle in which clinical and radiological findings were concluded to an ankle sprain and so a short leg was made along with oral´s analgesics and protected weight-bearing for two weeks. Following this, the pain had decreased but he reported recurrent episodes of a giving-away feeling of the ankle in sitting or kneeling. He could reproduce the dislocation by active dorsiflexion-eversion of his ankle. On the examination, he presented no deformity or wound. The palpation of the lateral side of the ankle was slightly painful. The subluxation of the peroneal tendons clinically appeared. The peroneal tendons dislocation test was positive. The X-rays of the ankle were normal. A few days later, the patient underwent surgery. The retinaculum was re-attached under the lip of the fibula by three anchors using the retromalleolar approach. After which, the ankle was placed in a below-knee, non-weight-bearing temporary cast for 2 weeks. Then walker boot cast with fully weight-bearing was allowed for 4 weeks. Following this period, physiotherapy was started. At the last follow up, the patient did well with neither instability nor ankle pain.
