  • Recommendations for patient activity after knee replacement vary among surgeons

    During recovery after knee replacement surgery, exercise is critical. After initial recovery, patients will want to resume more strenuous activities. In addition to exercise prescribed by a physical therapist, several studies have shown patients who participated in athletic activities prior to surgery will want to continue this practice after surgery. However, how much activity and how strenuous this activity should be remains unclear.

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.

  • Differing pain control methods may offer similar outcomes in patients after unilateral TKA

    No significant differences in pain scores and mean morphine equivalent consumption were observed among patients who received either an intra-articular or periarticular injection of bupivacaine and morphine or a periarticular injection of liposomal bupivacaine to manage pain following unilateral total knee arthroplasty, according to a presenter here.

  • 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.
