This study compared component wear rates and pre-revision blood metal ions levels in two groups of failed metal-on-metal hip arthroplasties: hip resurfacing and modular total hip replacement (THR). There was no significant difference in the median rate of linear wear between the groups for both acetabular (p = 0.4633) and femoral (p = 0.0872) components. There was also no significant difference...

Total knee arthroplasty (TKA) is a well-established procedure, and has proven to be durable and effective for the treatment of advanced arthritis of the knee joint. Early TKAs did not include patellar replacement and anterior knee pain was reported after the procedure had been carried out. The incorporation of patellar resurfacing during TKA reduces anterior knee pain, although new complication...

background. Carbon dioxide (CO 2 ) laser resurfacing has become an increasingly popular procedure for the treatment of facial rhytides and solar damage. Yet despite ongoing advancements in laser technology, CO 2 laser resurfacing is still a riskladen procedure that may lead to complications such as infection. Occlusive dressings increase the healing rate and decrease pain intensity in patients ...

Background Young patients with osteonecrosis (ON) treated with THA often have suboptimal function and radiographic failure with eventual revision. Resurfacing may be an option because of potentially increased functionality and decreased radiographic failure, although neither has been confirmed in the literature. Questions/purposes We therefore compared the clinical scores and radiographic failu...

BACKGROUND Some studies have suggested that resurfacing patients are generally more active postoperatively than their conventional total hip arthroplasty (THA)counterparts, but controversy remains over whether this is a reflection of preferential use of resurfacing for younger and higher-activity patients. We hypothesized that, when controlling for preoperative activity levels, in addition to r...

BACKGROUND Shoulder resurfacing has regained popularity in recent years. This report presents the long-term (>20 years) results of this procedure with regard to patient satisfaction and implant survival. MATERIALS AND METHODS We followed up 61 patients who underwent shoulder resurfacing procedures (74 shoulders) for a minimum of 20 years or until death (7 additional patients were lost to foll...

INTRODUCTION Anterior knee pain following total knee arthroplasty is estimated to occur in 4-49% of patients. Some orthopedic surgeons use circumpatellar electrocautery (diathermy) to reduce the prevalence of postsurgical anterior knee pain; however, the extent of its use is unknown. MATERIALS AND METHODOLOGY In April 2009, a postal questionnaire was sent to all 98 departments of orthopedic s...

Introduction: The style and rate of resurfacing on Venus is among the key problem in the geologic history of this planet. There are two alternative models of resurfacing. The first is the model of catastrophic resurfacing [1]. It states that at some specific point (say, ~500 Ma ago) the entire surface of Venus was renewed and the observable population of crates began to accumulate. The model of...
