BACKGROUND Patella resurfacing in total knee arthroplasty is a contentious issue. The literature suggests that resurfacing of the patella is based on surgeon preference, and little is known about the role and timing of resurfacing and how this affects outcomes. METHODS We analyzed 134,799 total knee arthroplasties using data from the Australian Orthopaedic Association National Joint Replaceme...

Hip resurfacing is an alternative to total hip arthroplasty for the young and active patient likely to outlive traditional means of hip joint replacement. To optimize design on the hip resurfacing prosthetic stress profile in the proximal femur after hip resurfacing. The acetabular cup is implanted in much the same fashion as an uncemented total hip arthroplasty, however, implantation of the fe...

Resurfacing hip arthroplasty represents a new, alternative technology to standard total hip arthroplasty. We examined the perceptions about resurfacing after the Second Annual United States Comprehensive Course on Total Hip Resurfacing Arthroplasty, which was a multi-company sponsored educational event to advance general knowledge, basic science, and surgical skills relevant to this field. The ...

A comparison of pertinent preoperative and postoperative data relative to total hip resurfacing versus total hip arthroplasty (THA) would assist in evaluating current perceptions in outcome. We compared 50 consecutive metal-metal resurfacing replacements in 50 patients with 44 consecutive conventional total hip arthroplasties in 35 patients, who were implanted during the same time period, by th...

JISAKOS Published Online First: [please include Day Month Year] doi:10.1136/jisakos2016-000095 ABSTRACT Management of the patella during primary total knee arthroplasty remains an unanswered question. Internationally, there is significant variation in the approach to resurfacing with some geographic regions resurfacing almost universally, ...

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...

BACKGROUND Multiple therapies involving ablative and nonablative techniques have been developed for rejuvenation of photodamaged skin. Monopolar radiofrequency (RF) is emerging as a gentler, nonablative skin-tightening device that delivers uniform heat to the dermis at a controlled depth. OBJECTIVE We evaluated the clinical effects and objectively quantified the histologic changes of the nona...

BACKGROUND Neointimal hyperplasia after PTCA is an important component of restenosis. METHODS AND RESULTS Cultures of rabbit endothelial cells and smooth muscle cells (SMCs) were irradiated with different doses of nonablative infrared (1064-nm) radiation. Normalized viability index detected with nondestructive Alamar Blue assay and direct cell count were studied. Our experiments demonstrated ...

Microfocused ultrasound is a unique technology to treat skin laxity of the brow, lower face, and the rhytides of the décolletage. Over the past several years, the efficacy and safety of this device has been well documented and its adoption widespread. By delivering focused acoustic energy, which is converted to heat, this device creates predictable and reproducible microcoagulative zones that i...
