Abstract: Objectivesthe aim of this study was to evaluate the surgical technique and determine the initial results, with a minimum follow-up of two years, from total knee arthroplasty revisions in which trabecular metal cones made of tantalum were used at the Knee Surgery Center of the National Institute of Traumatology and Orthopedics (INTO) or at the authors’ private clinic between July 2008 and December 2010.Methodsten patients were included in the study prospectively, through clinical and radiographic evaluations.Re… Show more

“…The coupling mechanism between the metaphyseal sleeve and the diaphyseal stem as per our construct confers substantially enhanced load channelling as compared to the tantalum cones. Additionally, the hydroxyapatite-coated surfaces of our metaphyseal sleeves can attain desirable osseointegration, which in our opinion is comparable with that of the tantalum cones, as has been highlighted as one of the notable benefits when using the tantalum cones (Mozella et al [8], Fedorka et al [12], Brown et al [18]). The broaching technique used to prepare the metaphysis for the metaphyseal sleeve also ensures that there is good bone-implant contact and that there is no need for additional bone grafting, which is required to fill up gaps between the tantalum cones and adjacent bone as reported in two previously published series (Long and Scuderi [25], Meneghini et al [26]).…”

“…= 3.48°) (Table 3). Osseointegration was defined as an absence of radiolucency lines between the host bone and implant (Mozella et al [8]) and an increase in osteosclerosis at the bone-implant interface; all knees in our series demonstrated progressively increased osseointegration, especially between the radiographs taken at 6 weeks and 3 months post-surgery. No significant interval changes were noted on the radiographs acquired subsequently.…”

“…The criterion used to define osseointegration of the tantalum cones was the presence of a trabecular reaction at the trabecular metal interface of the host bone, as assessed by sequential radiographs and defined by the presence of bone sclerosis together with the absence of radiolucency lines according to Mozella et al. [15] and Potter et al. [16] .…”

“…During the radiographic observation, the criteria of the Knee Society’s evaluation and scoring system [17] , modified for long-stemmed revision prostheses [18] , were used to determine loosening or migration of prosthetic components or trabecular cones according to Mozella et al.
