  • Understanding a patient's mental health status before hip replacement surgery may improve education and care

    Patients taking antidepressants up to three years prior to undergoing a total hip replacement (THR) were more likely to report greater pain before and after surgery and less satisfaction with their procedure, according to new research presented at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS).


    According to the investigators, a patient's mental health status should be assessed prior to surgery and taken into consideration during post-operative care.

  • Knee replacement may lower a patient's risk for mortality and heart failure

    New research presented at the 2012 Annual Meeting of the American Academy of Orthopaedic Surgeons (AAOS) highlights the benefits of total knee replacement (TKR) in elderly patients with osteoarthritis, including a lower probability of heart failure and mortality.



    There were significant positives in the osteoarthritis TKR group: the risk of mortality was half that of the non-TKR group and the congestive heart failure rate also was lower, at three, five and seven years after surgery. There was no difference in diabetes rates among both groups. Depression rates were slightly higher in the TKR group during the first three years after surgery, though there was no difference at five and seven years.

  • 2 knee replacements may be better than

    "Our study found that the risk of developing a serious joint infection that required an additional knee revision surgery was two times higher in patients who had staged knee replacements compared to the patients who had both knees replaced at the same time (2.2 percent after staged knee replacements and 1.2 percent after bilateral knee replacements)," said John P. Meehan, MD, study author and orthopaedic surgeon from the University of California, Davis.

  • Depressive symptoms associated with disease severity in patients with knee osteoarthritis

    The results of a study presented today at the Annual European Congress of Rheumatology (EULAR 2018) demonstrate that among individuals with radiographic knee osteoarthritis (OA), decreased physical performance and greater structural disease severity are associated with a higher risk of experiencing depressive symptoms.

  • Urinary markers predict bone problems after hip replacement

    The levels of certain markers helped the investigators identify patients at risk for osteolysis long before the emergence of signs through imaging tests—in some cases 6 years before a diagnosis was made.

  • Study launched to see if weight loss surgery before knee replacement improves outcomes

    Could weight loss surgery before knee replacement improve outcomes or even eliminate the need for joint replacement in severely overweight patients? A study by researchers at Hospital for Special Surgery (HSS) aims to answer that question. Orthopedic surgeons often encourage obese patients considering knee replacement to try to lose weight before the procedure.
