[Angular synthesis in upper tibial valgus osteotomy in osteoarthritis. Apropos of a series of 544 cases]. / Synthèse angulaire dans l'ostéotomie tibiale haute de valgisation pour arthrose. A propos d'une série de 544 cas.

Five hundred and forty-four valgus osteotomies for medial compartment osteoarthritis of the knee have been performed by two teams working separately over a period of twenty years between 1964 and 1984. From this series the results of a technique which aims to combine precision of correction with stability of fixation have been assessed. The clinical results in the short and medium term are encouraging. Above all, it seems that improvement in the osteoarthritis can be maintained for ten years or more, that is to say greater than the mean expectation of life of the patients.
