Neglected congenital bilateral knee dislocation treated by quadricepsplasty with semitendinosus and sartorius transfer: A case report

Congenital knee dislocation (CKD) is a rare condition, which accounts for 1% of congenital hip dislocations. It can present as an isolated condition or coexist with other genetic disorders. Treatment options include serial casting, percutaneous quadriceps recession, and V-Y quadricepsplasty (VYQ). The pathogenesis and hereditary patterns of CKD are not fully understood, with most cases being familial. CKD is usually managed immediately after birth. However, in this report, the patient was neglected for 2 years.
