“…As in other inflammatory arthritic conditions involving young patients [21,23], cemented prosthesis among RA patients presented more failure due to aseptic loosening of the acetabular component than of the femoral (Table 2) [3,5,15,18,19,20,24]. The Charnley prosthesis in our series demonstrated a pattern similar to other series.…”

“…Although they are usually younger than those with osteoarthritis, the bone stock of RA patients are usually poorer because of the disease activity as well as the medical treatment, i.e., the use of nonsteroidal antiinflammatory drugs and steroids [3,15,18]. The results of cemented prostheses in RA patients are generally believed to be inferior when compared to those done for osteoarthritis [3,5,15,17,18,20,21,24], despite the lower activity level and the lower body weight of the patients. Recently the use of noncemented hip prostheses has been extended to RA patients, and the early results reported so far are quite promising [9,13,14,16].…”

“…Radiological loosening of the acetabular component was defined as Hodgkinson type 3 or 4 demarcation of the cup [12]. Femoral component loosening was defined as more than 5 mm of subsidence on plain radiograph, or a fracture of the cement or the stem, or a complete radiolucent line more than 2 mm in thickness [15].…”

“…Despite the lower activity level and the lower body weight of these patients, the literature has documented the relatively inferior long-term results of cemented THA among patients with RA [3,5,15,17,18,20,21,24]. Recently noncemented prostheses have also been used in RA patients, but there are only a few reports describing the short-term results [9,13,14,16].…”

Twenty-eight (11 cemented and 17 noncemented) total hip arthroplasties (THA) were performed in 20 patients with rheumatoid arthritis (RA). The average age at operation was 42.1 years and the average follow-up was 10.8 years. There were two deep infections requiring removal of the prosthesis. Three cemented acetabular cups and one cemented femoral component were revised due to aseptic loosening. One cemented cup was loosened radiologically. One PCA polyethylene liner was revised because of significant wear. Both cemented and noncemented femoral components are capable of providing respectable results in RA patients. The relatively inferior results of THA among RA patients is due not only to the fixation method, but also to the poorer bone quality.Résumé Vingt-huit arthroplasties totales de hanche (11 cimentées, 17 non-cimentées) ont été exécutées sur 20 malades atteints de polyarthrite rhumato. L'âge moyen à l'opération était de 42,1 ans et la durée moyenne de suivi de 10,8 années. Deux infections profondes ont nécessité l'ablation de la prothèse. Trois composants cotyloidiens cimentés et un composant fémoral cimenté ont été révisé à cause d'un descellement aseptique. Un composant cotyloidien montre un descellement radiographique. Un insert de polyéthylène a été remplacé à cause d'une usure notable. Les composants fémoraux cimentés et noncimentés ont la capacité de fournir un résultat acceptable dans le cas d'une polyarthrite rhumato. Les résultats relativement inférieurs des prothèses totales chez ces malades proviennent non seulement de la méthode de fixation mais aussi d'une mauvaise qualité osseuse.
