Background: Achondroplasia is a rare autosomal dominant disorder resulting in skeletal dysplasia. Any injury to the anterior cruciate ligament among people already suffering from achondroplasia results in devastating effects. In this report, the outcome of the hamstring graft arthroscopic reconstruction technique for anterior cruciate ligament injury in achondroplasia patients is assessed. The patient in the present case report exhibits the potential for excellent outcomes four months post-surgical follow-up on Lysholm Knee Scoring Scale. This encouraging result, ought to persuade surgeons to use the hamstring graft arthroscopic restoration approach in achondroplasia instances like these. Timely and excellent recovery in such complicated surgical cases, would reduce the obstacle to surgery for several patients with achondroplasia. It would also improve the methods of managing these patients with this particular surgical technique.
