Chronic dislocation of the knee is a rare condition due to a diagnostic mistake during emergency assessment. Usually, dislocation obliges the surgeon to carry out a broad assessment, with vascular and neurological examination, and a thorough assessment of joint injuries. The immediate and stable closed reduction can resolve neurovascular compression. The most serious late sequela is joint instability with impairment of ambulation and patient's autonomy. Treatment of neglected knee dislocation is surgical, that is, arthrodesis or arthroplasty, the latter representing the treatment of choice. The case described herein appears unique because of the clinical and radiographic features. Interestingly, over the years, the neurovascular bundle has inadvertently adapted to the posterior femur displacement without secondary damage.
