“…It is important to note that the polyethylene used in this series consisted of either gamma-irradiated in air polyethylene (for the 68 HG-I acetabular components) or non-crosslinked polyethylene (for the 32 Duraloc acetabular components). These results are comparable to or better than the results of other cementless hip replacement reports (Table 4) [1,2,5,7,9,12,14,16,22,24,[26][27][28][29]31].…”

The relatively high prevalence of thigh pain and stress shielding associated with the AML porous-coated cementless femoral component led to the development of the Prodigy, a femoral component with more extensive porous-coating and a distal polished bullet tip with medial diaphyseal relief to potentially decrease the flexural rigidity. We prospectively evaluated a cohort of 100 consecutive cementless total hip arthroplasties performed using this device. The minimum followup was 10 years (mean, 11.4 years; range, 10-12 years). At 10-year followup, 69 of the 86 patients (82 hips) were living, 14 patients with 15 hips were deceased, and three patients with three hips were lost to followup. No hips required a stem revision. Two patients (two hips) complained of thigh pain. All hips were bone ingrown. Distal tip radiolucencies and osteolysis occurred in 13 hips (17%) and none, respectively. Twenty-one hips (28%) demonstrated moderate or severe stress shielding. Only further followup will determine if this could be a clinical problem or one with revision surgery. These results encourage the authors to continue using second-generation extensively coated stems in their primary total hip arthroplasty constructs.

“…This is significantly different from what reported in a previous study, in which an increase in the femur at the tip of stems has been found (34). By using a high press-fit stem for the tibial component in rTKA we have observed a bone apposition at 3 and 6 months, and a lesser resorption at 24 months compared to the low press-fit implantation (53). Bone remodelling activity in THA and in rTKA is a process that seems to intensively develop during the first year after surgery, then reducing in the second year (32,34,47,(54)(55)(56)(57).…”

SummaryIntroduction. Recent acquisitions of the complex mechanisms of osseointegration between implants and host bone have gained attention, accordingly to the methods of evaluation of these interactions. DEXA analysis is considered an useful tool to assess such phenomena, in order to analyse in a quantitative manner the local metabolic activity of the bone, and to evaluate over the time the integration between host bone and prosthetic components. The purpose of the present study is to report about a preliminary experience in the analysis of osseointegration processes of patients undergoing a primary Total Hip Arthroplasty (THA) or a revision Total Knee Arthroplasty (rTKA). Materials and methods. Thirty patients undergoing THA and nineteen undergoing rTKA were included in this study. In fifteen cases of THA a standard cementless stem was used; in the other fifteen a short cementless stem was chosen. In all cases a cementless cup was implanted. In all patients undergoing rTKA, all implants had pressfit femoral and tibial diaphyseal stems; only the femoral component and the tibial plateau were cemented. DEXA evaluation was performed preoperatively, and at 3, 6, 12, and 24

“…Our series did support a higher failure rate of the cup A compared to the other cups. A review of the literature reveals several recent publications that support a good survivorship for this prosthesis [6,7,9,14]. Furthermore, our study provides results up to 18 years, with only two patients lost to follow-up, and includes information on three different acetabular components and the femoral stem prosthesis.…”

The purpose of this study was to evaluate the mid-to long-term survivorship of Bimetric cementless total hip replacement and assess how it is affected by the acetabular design. This was a retrospective analysis of 127 Bimetric cementless total hip replacements in 110 patients with a follow-up of 7-18 years. A single design stem and three different cementless metal-backed acetabular designs were used. Patients were assessed clinically using the Harris hip score and radiologically by independent review of current hip radiographs. There was only one case of aseptic loosening of the femoral stem. The earliest acetabular design showed a high failure rate whilst the latter two designs showed a 96% survivorship at a mean of 9.5 years. We conclude that a combination of the bimetric stem with either of the latter acetabular cup designs has a good mid-to long-term performance.Résumé l'étude de l'évaluation à moyen ou à long terme de la survie d'une prothèse sans cimentde type Bimétric. il s'agit d'une étude prospective de 127 prothèses totales de hanche chez110 patients avec un suivi moyen de 7 à 18 ans. Un seul dessin de tige fémorale et troisdessins différents de cupule métal back sans ciment ont été utilisés. Les patients ont étéévalués sur le plan clinique (score de Harris) et sur le plan radiologique. Un seul cas de descellement aseptique de tige fémorale a été retrouvé. Sur les troismodèles de cupule, le premier modèle montre un taux d'échec très important alors que les deuxderniers modèles ont un taux de survie de 96% à 9,5 ans de recul. En conclusion, nous pouvons affirmer que la combinaison d'une tige de type bimétric associéeaux modèles acétabulaires les plus tardifs ont permis un bon résultat moyen à long terme.
