    A new study, published November 15, in the journal Pain provides information on the trajectories of prescription drug use before and after hip-replacement surgery—total hip arthroplasty (THA), one of the most common types of joint replacement surgery. Hip-replacement surgery is commonly followed by long-term reductions in the use of prescription drugs for pain and insomnia.

    People with knees worn out by arthritis will get more pain relief from joint replacement surgery, but it has more risks and there's a good chance that less drastic approaches also would help. That's the bottom line from the first study to strictly test other treatments against knee replacement, an operation done hundreds of thousands of times a year in the U.S.

  • 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.

    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.

    The use of bisphosphonates, a group of drugs used to prevent hip breakages in women with osteoporosis, is associated with an increased risk of atypical fractures in this joint, understood as those that occur in less frequent locations. It has been established thus in the PhD thesis by Javier Gorricho-Mendívil, a graduate in pharmacy, and read at the NUP/UPNA-Public University of Navarre. The author advocates encouraging other preventive measures such as "strategies to reduce falls and an active lifestyle to improve bone density and health"

    A 48-year-old woman with a history of hypertension, rheumatoid arthritis treated with chronic prednisone, and a two-pack-per-week cigarette use, presented to clinic with 8 years of right knee pain. She had an intra-articular steroid injection with some relief 6 years ago. She denied any hip pain and uses a cane for ambulation. On physical examination she appears to be a healthy 5’2’’, 160-pound woman who walks with an antalgic gait. She has a 20° flexion contracture, with flexion limited to 90°, and a mild valgus deformity of her knee. The extremity was neurovascularly intact and she had full, painless hip range of motion.
