PURPOSE We evaluated the hypothesis that circulating tumor cells as determined using the CellSearch System would correlate with tumor volume, pathological stage and Gleason score in men with localized prostate cancer. MATERIALS AND METHODS Samples of blood (30 ml) were drawn from 97 men with localized prostate cancer before radical prostatectomy, on(More)
BACKGROUND Knees undergoing revision anterior cruciate ligament (ACL) reconstruction typically have more intra-articular injuries than do knees undergoing primary reconstruction. HYPOTHESIS Previous partial meniscectomy (PM) is associated with a higher rate of chondral lesions at revision ACL reconstruction, whereas previous meniscal repair (MR) is not(More)
BACKGROUND Open reduction and internal fixation is the treatment of choice for displaced intra-articular calcaneal fractures at many orthopaedic trauma centers. The purpose of this study was to determine whether open reduction and internal fixation of displaced intra-articular calcaneal fractures results in better general and disease-specific health(More)
A marked discrepancy exists in the reported mortality rates in patients with open pelvic fractures, ranging from 4.8% to 50%. A retrospective review of patients with open pelvic fractures was performed at three centers. Thirty-nine patients with open pelvic fractures were identified; the average age was 32. The average injury-severity score was 29 (13-75).(More)
We conducted a prospective, randomized, controlled trial to compare functional outcomes, complications, and reoperation rates in elderly patients with displaced intra-articular, distal humeral fractures treated with open reduction-internal fixation (ORIF) or primary semiconstrained total elbow arthroplasty (TEA). Forty-two patients were randomized by sealed(More)
BACKGROUND Microfracture, the standard of care, is recognized to be an incomplete solution for cartilage damage. BST-CarGel, a chitosan-based medical device, is mixed with autologous whole blood and is applied to a microfractured cartilage lesion in which it physically stabilizes the clot and guides and enhances marrow-derived repair. An international,(More)
The purpose of this study is to determine whether arthroscopic acromioplasty is equivalent or superior to open acromioplasty, in a prospective, randomized, controlled, blinded clinical trial. Seventy-one patients with a clinical diagnosis of impingement syndrome were randomized to arthroscopic or open acromioplasty. Nine were excluded because of(More)
OBJECTIVES To assess the treatment preferences of orthopaedic surgeons for displaced three- and four-part proximal humerus fractures. DESIGN Cross-sectional survey. SETTING Academic and nonacademic institutions across Canada. PATIENTS/PARTICIPANTS Members of the Canadian Orthopedic Trauma Society and the Joint Orthopedic Initiative for National Trials(More)
OBJECTIVE The efficacy and safety of BST-CarGel®, a chitosan scaffold for cartilage repair was compared with microfracture alone at 1 year during a multicenter randomized controlled trial in the knee. This report was undertaken to investigate 5-year structural and clinical outcomes. DESIGN The international randomized controlled trial enrolled 80(More)
BACKGROUND Radiofrequency technology for shoulder instability was rapidly adopted despite limited clinical evidence and a poor understanding of its indications. Reports of serious adverse events followed, leading to its abandonment. This paper presents findings from a multicenter randomized clinical trial evaluating the safety and efficacy of electrothermal(More)
