ACL Reconstruction in Patient with ACL Agenesis and Prior Transtibial Amputation: A Case Report.

ACL Reconstruction in Patient with ACL Agenesis and Prior Transtibial Amputation: A Case Report.

A 38-year-old male patient with congenital absence of the anterior cruciate ligament (ACL) and fibular hemimelia status post-transtibial amputation presented with knee instability and pain after sustaining a noncontact injury. After diagnosis of a lateral meniscal root tear and confirmed absence of an ACL, the patient underwent ACL construction with bone-patellar tendon-bone allograft and lateral meniscal root repair. The patient returned to his preinjury functional state without recurrent ACL injury or other complication at 2 years postoperatively./r/nACL reconstruction in a patient with ACL agenesis and concurrent transtibial amputation may improve knee stability and reduce likelihood of recurrent injury.
