Focal chondral defects of the knee, either due to trauma or other conditions such as osteochondritis dissecans, often fail to heal on their own and may be associated with pain, loss of function, disability, and the long-term complication of osteoarthritis. The ideal resurfacing technique would eliminate symptoms, restore normal biomechanics of the knee joint, and prevent the long-term emergence...

Revision of metal-on-metal (MoM) total hip arthroplasty (THA) or hip resurfacing is associated with high complication rates. The authors propose dual-mobility components as a surgical option and present short- to mid-term results of MoM hips revised with dual-mobility components. Eighteen consecutive hips that underwent revision of MoM THA or hip resurfacing using dual-mobility components were ...

OBJECTIVE To compare the histological and ultrastructural changes in skin collagen with mechanical dermabrasion and pulsed carbon dioxide laser resurfacing in the minipig model. SETTING Academic medical center. SUBJECTS Yucatan minipig animal skin model. MAIN OUTCOME MEASURES Comparison of light microscopic and ultrastructural (electron microscopic) changes in the skin following the 2 res...

The early designs of hip resurfacing implants suffered high rates of early failure, making it impossible to obtain valuable mid-term radiostereophotogrammetric (RSA) results. The metal-on-metal Birmingham Hip Resurfacing arthroplasty has shown promising mid-term results and we present here the first mid-term RSA analysis of a hip resurfacing implant. The analysis was performed in 19 hips at fiv...

Acne scars show a great variety in there clinica! appearance and therefore very often cannot be effectively corrected by a single treatment modality alone. Traditionally chemical peeling is continued with punch excision and also by dermabrasion. Laser skin resurfacing has been added to the numerous treatment options for acne scars. Whereas laser resurfacing showed good results in mild acne scar...

Bone surface strains were measured in cadaver femora during loading prior to and after resurfacing of the hip and total hip replacement using an uncemented, tapered femoral component. In vitro loading simulated the single-leg stance phase during walking. Strains were measured on the medial and the lateral sides of the proximal aspect and the mid-diaphysis of the femur. Bone surface strains foll...

Hip resurfacing is gaining popularity as an acceptable treatment option for young active patients with hip osteoarthritis. The Buechel-Pappas hip resurfacing system has a titanium alloy femoral and acetabular component with a polyethylene liner. The titanium nitride coating of the femoral component has been shown to have a very low wear rate during in vivo laboratory studies. Although it has be...

The aim of this study was to determine the medium to long term survivorship of the Birmingham Hip Resurfacing prosthesis in an independent series of young men. The medical records and radiographs of all men aged 55 and under who had undergone Birmingham hip resurfacing by the senior author were reviewed. Patients who had not attended recent follow-up or had been previously discharged were conta...

The purpose of this study was to compare clinical outcomes between ceramic-on-ceramic total hip replacement and metal-on-metal hip resurfacing arthroplasty in comparable groups of young active patients at a 3to 6-year follow-up. The first 250 patients (mean age, 49.54 years) of a series of 930 resurfacing arthroplasties were compared clinically and functionally with a series of 190 patients (me...

The aim of our study was to investigate whether placing of the femoral component of a hip resurfacing in valgus protected against spontaneous fracture of the femoral neck. We performed a hip resurfacing in 20 pairs of embalmed femora. The femoral component was implanted at the natural neck-shaft angle in the left femur and with a 10 degrees valgus angle on the right. The bone mineral density of...
