BACKGROUND AND PURPOSE We noticed that our instruments were often too hot to touch after preparing the femoral head for resurfacing, and questioned whether the heat generated could exceed temperatures known to cause osteonecrosis. PATIENTS AND METHODS Using an infra-red thermal imaging camera, we measured real-time femoral head temperatures during femoral head reaming in 35 patients undergoin...

The new generation of metal-on-metal hip resurfacing is becoming an increasingly popular alternative to total hip replacement in the younger and more active patient. Mid-term survivorship figures for osteoarthritic patients are comparable to that of patients receiving a total hip arthroplasty. However, individuals receiving a hip resurfacing for aetiologies other than OA, such as avascular necr...

There is a need of independent prospective studies about modern generation of hip resurfacing implants. The aim of this propective observational study was to compare the functional outcomes and revision rates with hip resurfacing arthroplasty and total hip arthroplasty and to present the preliminary results at 2 years. Patients included were recruited prospectively in the Partial Pelvic Replace...

We have examined the differences in clinical outcome of total knee replacement (TKR) with and without patellar resurfacing in a prospective, randomised study of 181 osteoarthritic knees in 142 patients using the Profix total knee system which has a femoral component with features considered to be anatomical and a domed patellar implant. The procedures were carried out between February 1998 and ...

The objective of this study was to examine the effects of patellar resurfacing on patellofemoral joint contact pressure and contact area in total knee arthroplasty. We tested seven fresh-frozen cadaveric knees using a custom knee jig which permits the simulation of physiologic quadriceps loading. Before patellar resurfacing, the mean peak contact pressure of medial and lateral patellofemoral jo...

BACKGROUND Hip resurfacing is a conservative type of total hip arthroplasty but its use is controversial, especially in patients with osteonecrosis. The aim of this study was analysis of the clinical and radiographic outcomes of hip resurfacing in patients with osteonecrosis. MATERIAL/METHODS Between 2007 and 2008, 30 hip resurfacing arthroplasties were performed due to osteoarthritis seconda...

Objectives To compare the clinical and cost effectiveness of total hip arthroplasty with resurfacing arthroplasty in patients with severe arthritis of the hip. Design Single centre, two arm, parallel group, assessor blinded, randomised controlled trial with 1:1 treatment allocation. Setting One large teaching hospital in the United Kingdom. Participants 126 patients older than 18 years with sev...

Photodamage is one of the most common reasons that patients visit a dermatologist's office. Carbon dioxide (CO(2)) laser resurfacing has always been the gold standard for reversing photodamage. Because of the relatively high incidence of side effects and the prolonged downtime associated with CO(2) resurfacing, new technologies have emerged to address photodamage. Portrait skin regeneration (PS...

1. SA Brennan, JA Harty, C Gormley, SK O’Rourke. Comparison of acetabular reamings during hip resurfacing versus uncemented total hip arthoplasty. J Orthop Surg (Hong Kong) 2009;17:42–6. To the Editor: We read with interest the article by Brennan et al.1 They concluded that: “In hip resurfacing, the use of an appropriately small femoral component avoids oversizing the acetabular component and r...

BACKGROUND Changing the kinematic behaviour of patellar movement could be one of the reasons for anterior knee pain after implantation of a total knee arthroplasty (TKA). The aim of the current study was to measure the potential influence on patellar kinematics of patellar resurfacing during TKA. METHODS Patellar movement before and after TKA with and without patellar resurfacing was measured...
