• Blood Metal Ions Tied to Failed Hip Replacement, Resurfacing

    Raised levels of blood metal ions are associated with failed metal-on-metal hip resurfacings and total hip arthroplasties, according to a study published in the July 2 issue of The Journal of Bone & Joint Surgery.

    The researchers found that patients with failed arthroplasty had significantly higher blood cobalt and chromium ion levels than patients with non-failed arthroplasty (P < 0.01).

  • Partial knee replacement safer than total knee replacement

    Partial knee replacement surgery is safer than total knee replacement according to a new study published in The Lancet.

    Patients who had a partial knee replacement are 40 per cent more likely to have a re-operation, known as revision surgery, during the first eight years after the replacement, than those that had a total knee replacement.

  • Obesity may be driving increasing need for knee and hip replacements in steadily younger patients

    The impact of being overweight has far reaching health implications — implications that may be taking a toll at an earlier age.

    In a new study, researchers found that packing on the pounds may be setting the stage for total knee or hip replacement at increasingly younger ages.

    Further, the scientists found that being overweight or obese had a greater impact on the knee than the hip.

  • New approach to total knee replacement spares muscle, decreases pain

    Total knee arthroplasty, also known as total knee replacement, is one of the most commonly performed orthopedic procedures. According to the American Academy of Orthopedic Surgeons, as of 2010, more than600,000 total knee replacements were being performed annually in the United States. The number of total knee replacements performed annually in the U.S. is expected to grow by 673 percent to 3.48 million procedures by 2030.

    To start, a rigorous preoperative optimization process is now in place to help minimize the risk of complications after surgery. Patients also attend a joint education class to be advised of what to expect before, during and after the surgery. Studies have shown that these educational classes improve patient outcomes.

  • Semi-constrained implant improves revision knee arthroplasty outcomes

    Use of a semi-constrained implant in revision knee arthroplasty produced acceptable implant survival and functional outcomes during the long-term follow-up period, according to study results.

  • Are doctors performing too many unnecessary knee-replacement surgeries?

    More than one-third of total knee replacements performed in the U.S. were deemed "inappropriate" in a new study that used a patient classification system to weigh the risks and benefits.

    The study, published June 30 in the journal Arthritis & Rheumatology, looked at 175 people who underwent total knee replacement surgery.

  • Ask a Sports Medicine Doc: Hip injuries among youth

    Q: My 14 year old daughter is a competitive ski racer and has been having hip pain. Could she have a labral tear?

    A: Hip injuries are on the rise in adolescent athletes. This is due to the increasing number of young athletes participating in organized sports as well as advances in technology that have improved clinician’s diagnostic ability.

  • Smith & Nephew DYONICS(TM) PLAN brings first-of-its-kind, individualized surgical planning to hip arthroscopy

    Smith & Nephew (NYSE:SNN;LSE:SN), the global medical technology business, will launch its DYONICS PLAN Hip Impingement Planning System at this week's American Academy of Orthopaedic Surgeons (AAOS) annual meeting in New Orleans. Unlike standard imaging tools, DYONICS PLAN is a revolutionary 3D software system that allows surgeons to visualize, assess and generate a comprehensive surgical report for each patient's unique Femoroacetabular impingement (FAI) surgery before that patient ever enters the operating room.

  • MRI to 'see through' metal screws developed to follow patients after hip fracture surgery

    People who sustain the most common type of hip fracture are at increased risk of complications. A special type of MRI has been developed that can show a detailed image following fracture repair, without the distortion caused by metal surgical screws that are problematic in standard MRIs. Each year, more than 340,000 people suffer a broken hip in the United States.

  • Genetics may explain high-functioning senior athletes with hip abnormalities

    Genetics may explain why some senior athletes are high functioning despite having one or both hip abnormalities typically associated with early onset osteoarthritis: developmental dislocation of the hip (dysplasia), a loose hip joint; or femoroacetabular impingement (FAI), a condition in which the hip bones are abnormally shaped.
