fa جراحی زانو Knee surgery گزارش مورد Case Report <div style="text-align: justify;"><strong>Introduction</strong>: Ankle dislocations are a group of injuries requiring immediate orthopedic interventions to avoid subsequent neurovascular complications and impairments. In most cases, they are associated with a malleolar fracture in the ankle. However, in the sporadic cases, especially the ones due to high-energy traumas, ankle dislocations are not associated with malleolar fractures and are referred to as &quot;pure ankle dislocations&quot;.<br> <strong>Case Presentation</strong>: Here, we report a rare case of pure ankle dislocation in a 38-year-old female athlete with no previously established predisposing risk factors. The patient was referred to our emergency department following a catastrophic fall down during exercise, resulting in severe ankle pain and deformity. The patient was treated with urgent reduction of the displacement and 6 weeks of immobilization by casting followed by intensive physiotherapy.<br> <strong>Conclusion</strong>: At the end of the 3-month follow-up, no symptoms of instability were observed, and the patient could walk normally; at the 6-month follow-up, the patient could perform her sport activates similar to the initial level.</div> Pure ankle dislocation, Range of motions and rehabilitation, Tibiotalar joint, Ankle ligament, Ankle instability, Orthopedics 23 26 http://jros.iums.ac.ir/browse.php?a_code=A-10-41-71&slc_lang=fa&sid=1 Mehdi Moghtadaei 10031947532846003851 10031947532846003851 No Department of Orthopedics Surgery, Hazrate Rasoole Akram Hospital, Iran University of Medical Sciences, Tehran, Iran.
