    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 bisphosphonate drugs is associated with an increased risk of atypical hip fractures

    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.

    Few joint replacement surgeons were exposed to the direct anterior approach for total hip arthroplasty during their residency and fellowship – which means they’ll need additional training if they want to offer this approach to their patients.

  • Women fare better than men following total knee, hip replacement

    While women may have their first total joint replacement (TJR) at an older age, they are less likely to have complications related to their surgery or require revision surgery, according to a new study presented today at the 2015 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS). The findings contradict the theory that TJR is underutilized in female patients because they have worse outcomes then men.

    48 percent of hip fracture patients, age 65 and older, had delirium, or acute confusion, before, during and after surgery (perioperative), resulting in significantly longer hospital stays and higher costs for care, a new study concludes.

  • Weight-loss surgery before joint replacement can improve outcomes in severely overweight patients

    Bariatric surgery prior to joint replacement is a cost-effective option to improve outcomes in severely overweight patients, research demonstrates. It is well-known that obesity takes a toll on one's health. Bariatric surgery and subsequent weight loss reduces the risk of heart disease, diabetes and even some forms of cancer. But before now, the effect of bariatric surgery on joint replacement outcomes was not known.
