  • Newer UKR prosthesis for patients with osteoarthritis achieved satisfactory results

    Patients who received a newer prosthesis similar to the Miller-Galante knee design showed significantly better Knee Society function scores than patients who had a long-used prosthesis to which it was compared. However, the two implants performed about the same at short-term follow-up, according to a presenter.

  • Shorter hospital stay for hip fracture associated with increased odds of survival

    The longer a hip fracture patient stays in a hospital, the more likely that patient will die within 30 days of leaving, according to a study led by chair of the Department of Orthopaedic Surgery at the Virginia Commonwealth University School of Medicine.

  • Lifelong physical activity increases bone density in men

    Men have many reasons to add high-impact and resistance training to their exercise regimens; these reasons include building muscle and shedding fat. Now a University of Missouri researcher has determined another significant benefit to these activities: building bone mass. The study found that individuals who continuously participated in high-impact activities, such as jogging and tennis, during adolescence and young adulthood, had greater hip and lumbar spine bone mineral density than those who did not.

  • Obesity and total joint arthroplasty: Time to examine needs in a different light

    The prevalence of obesity in the general population is increasing. Obesity is estimated to affect approximately one-third of adults in the United States. It is estimated that 6.1 million patients who undergo total joint arthroplasty will be obese by 2040.

  • Activity could help keep knees lubricated

    Cartilage is filled with fluid - about 80% of the volume of the cartilage tissue - that plays the essential roles of supporting weight and lubricating joint surfaces. Loss of this fluid, called synovial fluid, results in a gradual decrease in cartilage thickness and increase in friction, which is related to the degradation and joint pain of osteoarthritis. Since cartilage is porous, fluid is readily squeezed out of the holes over time. Yet the symptoms associated with osteoarthritis usually take decades to develop. Researchers have now proposed a mechanism that explains how motion can cause cartilage to reabsorb liquid that leaks out.

  • Satisfactory results seen in revision THA with acetabular reinforcement, HA granules, autograft

    Using acetabular revision for loosening as an endpoint, investigators of this study found more than 90% acetabular component survival at 10 years among patients who underwent revision total hip arthroplasty for acetabular bone deficiency using a Kerboull-type acetabular reinforcement device to support hydroxyapatite granules and structural autograft.

  • Prevalence of Total Hip and Knee Replacement in the United States

    Background: Descriptive epidemiology of total joint replacement procedures is limited to annual procedure volumes (incidence). The prevalence of the growing number of individuals living with a total hip or total knee replacement is currently unknown. Our objective was to estimate the prevalence of total hip and total knee replacement in the United States.
