..Expedited access resulted in a larger proportion of patients with better than expected function 12 months after surgery...

..Level of Evidence: Level I, randomized clinical trial. See Guidelines for Authors for a complete description of levels of evidence...

..Dislocation after revision THA is a common complication. Large heads have the potential to decrease dislocation rate, but it is unclear whether they do so in revision THA...

..We presume reduced stiffness of the titanium stem, coupled with the intraoperative modularity, resulted in the improved patient outcomes observed in this study...

..We evaluated the effect of alendronate-coated porous tantalum on new bone formation in an animal model incorporating a gap between the implant and bone...

..Methicillin-resistant hip infections are increasingly common. Reports of the surgical management of these patients using two-stage THA show variable control of infection, but all reports used static spacers...

..Level of Evidence: Level III, therapeutic study. See Guidelines for Authors for a complete description of levels of evidence...

..At a mean of 41 months, none of the outcomes were significantly worse for the septic group, which had 2 recurrences of infection (4%). The satisfactory functional results of the PROSTALAC system may be related to the design features...

..The FHSA cohort was found to have significantly better outcome scores. This study demonstrates improved clinical outcomes for patients undergoing revision TKA using a structural allograft compared with those without...

..Knowledge of rates and predictors of return to sports will help inform expectations in patients anticipating return to sports after joint arthroplasty...

..While many papers report function in these patients, they do not describe the quality of life...

..The PROSTALAC knee spacer is an antibiotic-loaded cement articulating spacer that allows some movement of the knee between stages. Whether motion enhances long-term function is unknown...

..The current AMP-CaP coating thus offers in vivo osteoconductivity to orthopedic implants. It also offers in vitro antimicrobial property, with its in vivo performance to be confirmed in future animal infection models...

..Whether a smooth metal shell needs to be roughened as well is a matter of debate...

..If there is not enough room for a posterior pelvic reconstruction plate, a cup-cage construct with or without an allograft can be used as a reconstruction option...

..A secondary purpose was to assess whether a correlation exists between elevated serum metal ion levels and pseudotumor formation...

..The purpose of this study was to evaluate the diagnostic test characteristics of the erythrocyte sedimentation rate and C-reactive protein level for the assessment of infection in patients presenting for revision total knee arthroplasty...

....

..The absence of a patellar prosthesis does not appear to significantly affect pain, function, or satisfaction outcomes after revision total knee arthroplasty...

....

..5, P = .016) than in patients who had revision THA. The magnitude of improvement in quality of life is greater for the patient with primary THA in comparison to the patient with revision THA...

..The results of these treatment regimens and the rationale for cementless reconstruction at the second stage of a two-stage treatment protocol are important considerations in the treatment of periprosthetic infection...

..Periprosthetic fractures of the femur are a complex surgical problem and require specialized training in a range of surgical techniques...

....

..In November 2003, government legislation established the Blood Utilization Program at our center to reduce the rate and risks associated with allogenic transfusion...

..Also, as the soft-tissue attachments to the bone fragment are preserved in this approach, abductor muscle tension can be adjusted...

..Recent literature demonstrates that the ETO has a relatively low rate of nonunion and is associated with fewer intraoperative femoral fractures or cortical perforations, as well as decreased surgical time...

..This review focuses on the treatment of these Vancouver type B3 fractures with long-stem implants, proximal femoral replacements, allograft-prosthesis composites and cortical strut grafting...

....

..These findings may be related to the articulating features of the PROSTALAC system, which permits full active movement of the knee in the early postoperative period...

..At mid-term follow up both the RP and FB give equivalent results, but patients with the RP tended to have a higher activity level score...

..The reliability of recall remained high up to 3 months postoperation. Patients are able to accurately recall their preoperative function for up to 3 months after total hip arthroplasty...

..However, given the results of this study, in patients older than 40 years, periacetabular osteotomy should only be done in highly selected cases...

..05) in comparison with primary TKA patients. When adjusting for confounding factors in regression analyses, revisions are inferior to primary TKA by 8.6 (95% confidence interval, 2.7-14.6) normalized WOMAC units...

..We sought to evaluate the clinical and radiographic outcomes, complications and satisfaction with THA among patients with corticosteroid-induced osteonecrosis...

....

..Validated patient-reported results are essential to guide patients and surgeons in the current era of informed and shared decision making...

..The surgical alternatives are numerous and include the use of allografts, both structural and morcellized; cemented and cementless femoral components; and segmental replacement megaprostheses...

..We also show that the mechanical jig resulted in significantly retroverted implant placement. There was no significant difference in operative time between the two techniques...

..The objective is to develop criteria that classify individual treatment health related quality of life (HRQOL) outcome after primary THA, adjusted by preoperative scores...

..The OHS also demonstrates similar floor and ceiling effect patterns as does the WOMAC. We recommend that the choice should depend on which scale researchers are using to power a study...

..The purpose of this study is to investigate a new sequential compression device with feedback to maintain optimal therapy, and to determine whether therapy is improved with this new device...

..With approximately 200,000 THAs performed annually in North America, fracture prevention is extremely important for the individual patient and has a significant impact on the health care system...

..Previous reports have cited high failure rates with cylindrical cobalt chrome stems in large femoral defects but the longer term survival of the fluted stems is unknown...

..Particularly when pain is caused by occult infection, erythrocyte sedimentation rate, C-reactive protein level, hip aspiration, advanced radiologic imaging, and nuclear medicine scans can help determine the diagnosis...

..At follow-up, the groups differed only in the Oxford score: median 83 (mobile) and 90 (fixed). There is no difference in outcomes between mobile and fixed unicompartmental knee replacements...

..When patients are selected appropriately, an isolated liner exchange can significantly improve the function of the knee...

..These results,however, have been achieved by a small number of high-volume surgeons, and the authors feel it is essential that as these techniques are introduced into widespread practice the results be studied carefully...

..Some commonly used classifications of musculoskeletal conditions have not proved to be reliable when critically evaluated...

..The purpose of this study was to evaluate the risk factors and frequency of intraoperative fractures with the use of these stems and their effect on radiographic and functional outcomes...
