Abstract
The use of the Sheehan knee prosthesis extended from 1971 to 2002. It incorporated a semi-constrained hinge with intra-medullary stems cemented into the femur and tibia. While some authors have reported excellent short-term results, others have reported revision rates of up to 31% at 5–10 years. The aim of this study was to review the senior author’s experience in revising these arthroplasties. We review 54 Sheehan total knee replacements and discuss the difficulties encountered during first and subsequent revisions and the often-complex reconstruction techniques used to overcome these.
Résumé
L’utilisation de la prothèse de genou de type Sheehan s’est étendue de 1971 à 2002. Elle comportait une charnière semi-contrainte avec des tiges intra-médullaires cimentées dans le fémur et le tibia. Tandis que d’excellents résultats à court terme ont été rapportés par quelques auteurs, un taux de révision jusqu’à 31% à 5–10 ans a été rapporté par d’autres. Le but de cette étude était examiner l’expérience de l’auteur senior dans la révision des prothèses de Sheehan. Nous avons examiné 54 prothèses et discutons les difficultés rencontrées pendant l’arthroplastie initiale et les révisions ultérieures ainsi que les techniques souvent complexes de reconstruction utilisées pour les mener à bien.
