“…This might be explained by progressive impairment in work motivation induced by the disability pension-an explanation in accordance with our results in the NHP part of the investigation, where patients on partial or complete disability pension showed impairment in the psychological categories but not in the physical capacity categories. The overall results from the NHP questionnaire were similar to those of other published studies after knee prosthetic surgery (Rissanen et al 1995, Hilding et al 1997; Table 5). …”

“…In addition, oxidized zirconium femoral heads have been developed; the design rationale of this surface was the combination of ceramic wear characteristics and the mechanical properties of the metallic substrate [1,5,16,17]. In clinical terms, XLPE has been combined with cobalt-chrome, ceramic, and oxidized zirconium femoral heads [12,29,[33][34][35]. However, the in vivo midterm wear performance of the two existing sizes [3,7] of oxidized zirconium femoral heads has not been compared with that of ceramic heads.…”

Background Osteolysis resulting from wear debris production from the bearing surfaces is a major factor limiting long-term survival of hip implants. Oxidized zirconium head on crosslinked polyethylene (XLPE) is a modern bearing coupling. However, midterm in vivo wear data of this coupling are not known. Questions/purposes The purpose of this study was to investigate in vivo whether the combination of an oxidized zirconium femoral head on XLPE produces less wear than a ceramic head on XLPE or a ceramic head on conventional polyethylene (CPE) couplings and whether any of these bearing combinations results in higher hip scores. Methods Between 2003 and 2007, we performed 356 total hip arthroplasties in 288 patients; of those, 199 (69.1%) patients (199 hips) were enrolled in what began as a randomized trial. Unfortunately, after the 57 th patient, the randomization process was halted because of patients' preference for the oxidized zirconium bearing instead of the ceramic after (as they were informed by the consent form), and after that, alternate allocation to the study groups was performed. Hips were allocated into four groups: in Group A, a 28-mm ceramic head on CPE was used; in Group B, a 28-mm ceramic head on XLPE; in Group C, a 28-mm Oxinium head on XLPE; and in Group D, a 32-mm Oxinium head on XLPE. The authors prospectively collected in vivo wear data (linear wear, linear wear rate, volumetric wear, and volumetric wear rate) using PolyWare software. Preoperative and postoperative clinical data, including Harris and Oxford hip scores, were also collected at regular intervals. Of those patients enrolled, 188 (95%) were available for final followup at a minimum of 7 years (mean, 9 years; range, 7-12 years). Results All bearing surfaces showed a varying high bedding-in effect (plastic deformation of the liner) up to the second postoperative year. At 5 years both oxidized zirconium on XLPE groups showed lower (p \ 0.01) volumetric wear (mean ± SD mm 3 ) and volumetric wear rates (mean ± SD mm 3 /year) ( Res (2015) 473:3836-3845 DOI 10.1007 Clinical Orthopaedics and Related Research ® A Publication of The Association of Bone and Joint Surgeons® (Group C: 356 ± 64 to 215 ± 54 mm 3 /year, Group D: 354 ± 50 to 210 ± 64 mm 3 /year) when compared with ceramic on CPE (Group A: 895 ± 131 to 380 ± 80 mm 3 /year) and ceramic on XLPE (Group B: 1625 ± 253 to 480 ± 101 mm 3 /year) groups. When wear rates of both oxidized zirconium groups were compared, no differences were found at any time interval with the numbers available. Two hips (one from Group A and one from Group B) are scheduled for revision as a result of wear and osteolysis. There were no differences in hip scores among the groups with the numbers available. Conclusions In this study, in vivo wear parameters were lower when the combination of an oxidized zirconium head on XLPE liner was used at an average of 9 years (range, 7-12 years) followup. Further larger-scale clinical studies should confirm these findings and evaluate osteolysis and revision rates...

“…Total knee arthroplasty (TKA) is indicated to reduce pain and improve physical function and quality of life (1)(2)(3)(4)(5)(6)(7)(8)(9). Recently, physical function was identified by a consensus of research experts in osteoarthritis (OA) as one of the most important dimensions to be measured when evaluating intervention effectiveness (10).…”

Objective. To identify preoperative predictors of locomotor ability 2 months after total knee arthroplasty (TKA). Methods. Sixty-five participants scheduled for a first TKA were recruited. The dependent variable was the distance covered during the 6-minute gait test 2 months after TKA. The independent variables, measured before surgery, were grouped into 3 categories: 1) personal; 2) organic system, and 3) capability variables. Multiple regression analyses were conducted to determine the best predictors of the dependent variable. Modified cross-validation of the model combining predictors from the three categories was obtained with 10 random samples derived from the original cohort by resampling with replacement. Results. Predictors were identified in the 3 categories: 1) gender, number of comorbidities, body mass index, 2) knee pain, flexion and strength, lower limb mechanical power, and 3) preoperative 6-minute gait distance. When these variables were modeled together only the preoperative 6-minute gait distance and knee pain and flexion remained significant (adjusted R 2 ‫؍‬ 0.66). Conclusion. Using variables easily measured before surgery, it is possible to predict with good accuracy locomotor ability 2 months after TKA.
