When secondary patellar resurfacing is performed, a uniformly and widely used scoring system that is validated for anterior knee pain caused by a retropatellar degeneration will give more insight into the results of this procedure. The cause of anterior knee pain following total knee arthroplasty (TKA) is not always related to the patella itself. Other causes have been identified, such as an in...

BACKGROUND Cutaneous aging is manifested by rhytides, dyschromias, and skin laxity. Ablative laser skin resurfacing can effectively improve many signs of skin aging; however, the photoaged patient with facial laxity often requires a surgical lifting procedure in order to obtain optimal results. Concerns with delayed or impaired wound healing has led to reluctance to perform both procedures simu...

We studied 40 patients in whom the patella was not severely deformed and who were undergoing primary total knee arthroplasty (TKA) for osteoarthritis by one surgeon using one type of prosthesis. They were randomly allocated either to have the patella retained or resurfaced with a cemented, all-polyethylene component regardless of the state of the patellar articular cartilage. Apart from removal...

BACKGROUND While skin resurfacing using pulsed carbon dioxide lasers appears to have a skin-tightening effect clinically, the debate continues over its actual effects on dermal collagen. OBJECTIVES To provide quantitative measures of skin elasticity changes associated with pulsed carbon dioxide laser skin resurfacing and to introduce to the facial plastic surgery community the Cutometer SEM 5...

BACKGROUND Cutaneous laser resurfacing is a well-accepted modality, with excellent clinical outcomes and low morbidity rates, for the treatment of a variety of epidermal and dermal lesions. The use of antibiotic prophylaxis continues to be an area of controversy, with laser practitioners divided in their approach. OBJECTIVE To identify the rate of postoperative bacterial infection following f...

BACKGROUND Hypopigmentation is a relatively common side effect of CO2 laser resurfacing. Little is known regarding the histologic features of the areas of pigmentation loss. To date, hypopigmentation is considered a permanent complication of this procedure. OBJECTIVE To assess the histologic features of hypopigmentation caused by laser resurfacing and to evaluate the efficacy and safety of to...

Short-term femoral neck fracture is a primary complication associated with contemporary hip resurfacing. Some fractures are associated with neck notching, while others occur in the absence of notching. These unexplained fractures may be due to large magnitude strains near the implant rim, which could cause bone damage accumulation and eventual neck fracture. We used statistically augmented fini...

The current depth and breadth of experience in hip resurfacing in Canadian academic centers is not well known. This study endeavors to increase awareness of the prevalence of programs and current experience in a select number of representative teaching centers by examining the learning curve of high-volume surgeons. A questionnaire was sent to all academic centers in Canada to identify the volu...

Hip resurfacing arthroplasty is known to improve quality of life (QoL) and allow increased activity levels in young patients. It is, however, traditionally offered to the younger age group of patients, largely those aged under 60 years. We studied 42 consecutive patients (42 hips) aged 60 years or over (mean age 64) and 41 consecutive patients (42 hips) under this age (mean age 49), all of whom...

Postoperative anterior knee pain was evaluated in a consecutive series of 138 knees in 108 patients with rheumatoid arthritis treated by total knee replacement with Mark I Insall-Burstein prostheses. No knee had primary patellar resurfacing, and in the 119 knees followed up for a mean of 63.9 months, none had secondary resurfacing. Anterior knee pain was absent in 87 knees (73%), mild in 16 (13...
