Multiple pterygium syndrome, a subgroup of arthrogryposis multiplex congenita, is characterized by the webbing of different parts of the body. We describe a child who developed 140° flexion contractures of the popliteal fossa, which complicated mobility, skin care, and general hygiene. After seeking multiple opinions, the parents elected to proceed with through-knee amputation of both knees. At 6 month follow-up, the child had been fitted with bilateral prostheses and was able to ambulate with assistance. The findings of the current case suggest that in extreme cases of multiple pterygium syndrome, through-knee amputations may represent a predictable and functional treatment option that should be considered.
