Body mass index as a predictor of complications after operative treatment of acetabular fractures.
Obesity, a growing public health concern, is often thought to be an important risk factor for postoperative complications. We hypothesized that body mass index is predictive of complications after operative treatment of acetabular fractures. ⋯ Body mass index is predictive of complications after operative treatment of acetabular fractures.

Meta Analysis Comparative StudyPatellar resurfacing in total knee arthroplasty. A meta-analysis.
Patellar resurfacing during total knee arthroplasty remains controversial. We aimed to evaluate the effectiveness of this technique through an evaluation of the current literature. ⋯ The available evidence indicates that patellar resurfacing reduces the risks of reoperation and anterior knee pain after total knee arthroplasty. The observed effects are clinically important despite their modest magnitude. Additional, carefully designed randomized trials are required to strengthen this claim.

Randomized Controlled Trial Comparative Study Clinical TrialComparison of soap and antibiotic solutions for irrigation of lower-limb open fracture wounds. A prospective, randomized study.
Irrigation of open fracture wounds is a commonly performed procedure, and irrigation additives have been used in an attempt to reduce the risk of infection. In vitro and animal studies have suggested that irrigation with detergent solution is more effective than irrigation with a solution containing antibiotic additives. This study was performed to compare the efficacy of those two solutions in the treatment of open fractures in humans. ⋯ Irrigation of open fracture wounds with antibiotic solution offers no advantages over the use of a nonsterile soap solution, and it may increase the risk of wound-healing problems.

Early osteolysis following second-generation metal-on-metal hip replacement.
Total hip arthroplasty with use of metal-on-metal bearings has been reintroduced as an alternative to the use of metal-on-polyethylene bearings because of theoretical advantages such as reduced wear and a lower prevalence of osteolysis. However, we observed early osteolysis in a cohort of patients who had been managed with second-generation metal-on-metal hip replacements and investigated the possible etiologic role of metal hypersensitivity. ⋯ These findings raise the possibility that early osteolysis in patients with this second-generation metal-on-metal hip replacement is associated with abnormalities consistent with delayed-type hypersensitivity to metal. A prospective study in which a large group of patients is evaluated with multiple diagnostic methods is needed in order to establish whether there is a causal relationship between metal hypersensitivity and osteolysis.

Prevalence of primary and revision total hip and knee arthroplasty in the United States from 1990 through 2002.
The purpose of this study was to quantify the procedural rate and revision burden of total hip and knee arthroplasty in the United States and to determine if the age or gender-based procedural rates and overall revision burden are changing over time. ⋯ The reported prevalence trends have important ramifications with regard to the number of joint replacements expected to be performed by orthopaedic surgeons in the future. Because the revision burden has been relatively constant over time, we can expect that a greater number of primary replacements will result in a greater number of revisions unless some limiting mechanism can be successfully implemented to reduce the future revision burden.
