  • Resident performance in knee arthroscopy may improve with cadaveric skills labs, simulators

    Residents who trained with cadaveric skills labs and simulators experienced improved performance in knee arthroscopy compared with residents who did not, according to results presented at the American Orthopaedic Association Annual Meeting.

  • TKA mechanical alignment more accurate on hip-knee-ankle radiograph vs. anteroposterior radiograph

    Standardized anteroposterior radiographs were insufficient for the accurate assessment of the mechanical alignment of total knee arthroplasty compared with hip-knee-ankle radiographs. Additionally, anteroposterior radiographs exaggerated the varus appearance of mechanical alignment in implants, according to study results.

  • Poorer outcomes observed for revision unicompartmental knee arthroplasty vs primary TKA

    Compared with primary total knee arthroplasty, revision unicompartmental knee arthroplasty was correlated with poorer outcomes; however, researchers theorized this may have been a result of poorer preoperative function.

  • Most patients able to safely drive 2 weeks after THA

    Most patients’ brake reaction time had returned to baseline level or better within 2 weeks of undergoing total hip arthroplasty, allowing the patients to be able to drive safely again, according to study results.

  • TOTAL FEMORAL ARTHROPLASTY FOR THE SALVAGED FEMUR

    Complicated revision total hip arthroplasty (THA) and total knee arthroplasty (TKA), septic prosthetic failure, and periprosthetic femoral fractures seem to be increasing. The expanding applications for arthroplasty in younger patients coupled with their longer lifespan is translating into more revision procedures. In addition, with the increasing population of older patients and the increasing number of THA and TKA procedures done in this population prostheses are being used in more osteoporotic bone and the incidence of periprosthetic fractures is increasing.

  • Subclinical hyperthyroidism associated with an increased risk of hip and other fractures

    In an analysis that included more than 70,000 participants from 13 studies, subclinical hyperthyroidism was associated with an increased risk for hip and other fractures including spine. Subclinical hyperthyroidism is a low serum thyroid-stimulating hormone concentration in a person without clinical symptoms and normal thyroid hormone concentrations on blood tests.

  • University of Iowa team developing bioactive gel to treat knee injuries

    Injectable gel encourages self-healing of cartilage Knee injuries are the bane of athletes everywhere, from professionals and college stars to weekend warriors. Current surgical options for repairing damaged cartilage caused by knee injuries are costly, can have complications, and often are not very effective in the long run. Even after surgery, cartilage degeneration can progress leading to painful arthritis.

  • Researchers find clues that may predict recovery outcomes following total hip replacement

    Surgery to replace the arthritic hip and knee joints is on the rise in the U.S., with more than 1.1 million replacement surgeries reported in 2009. While these surgeries improve pain, mobility and quality of life for most recipients, some patients are dogged by persistent muscular problems. Now, a cross-institutional team of researchers has found that a patient's susceptibility to muscle inflammation may be a measurable marker that can be used to predict how well that patient will recover from joint replacement surgery and to identify those patients who may be in need of a specialized rehabilitation plan.

  • An Anterior-based Muscle-sparing Approach to THA

    A 66-year-old female who has acetabular protrusio and end-stage osteoarthritis of the right hip undergoes total hip arthroplasty through the ABMSparing approach. According to the authors, this approach avoids the complications of wound healing that can occur with an approach that crosses the hip flexion crease, as well as avoids cutting muscle.

  • What Is the Future of Mobile-bearing Acetabular Components?

    Mobile-bearing acetabular components are a relatively new design option for total hip arthroplasty. The goal of these components, say the manufacturers, is to allow a better fit with the patient s anatomy, provide greater mobility, and create a stable hip that s less prone to dislocation.
