Abstract
The congenital absence of the anterior cruciate ligament (ACL) and posterior cruciate ligament (PCL) is an extremely rare condition, with an estimated prevalence of 0.017 per 1,000 live births for ACL agenesis. The authors present the case of a 15-year-old adolescent girl with autosomal dominant multiple synostosis, who developed progressive bilateral knee pain and functional limitations. Bilateral knee x-rays revealed trochlear dysplasia and an absent tibial eminence, suggesting a congenital ligamentous abnormality. Magnetic resonance imaging confirmed the bilateral absence of both the ACL and PCL. Surgical reconstruction of both ligaments was performed, with the first procedure taking place in October 2024. Postoperatively, the patient followed a rehabilitation protocol in physical therapy. This case underscores the rarity of bilateral ACL and PCL agenesis and the importance of timely surgical intervention to alleviate symptoms and improve function.
