    Patients who underwent early total hip arthroplasty experienced better 10-year cup and stem survival compared with patients who underwent late total hip arthroplasty, according to study results.

    Researchers searched the Medline databases from January 1990 to January 2014 and retrieved 19 articles reporting on the management of posttraumatic arthritis of the hip following acetabular fractures with the use of late total hip arthroplasty (THA), as well as articles where acetabular fractures were treated with early THA. In all, the researchers assessed THA outcomes following acetabular fracture in 654 patients.

  • Most dislocated hips placed within ‘safe zone’ during THA, study finds

    DALLAS — During their minimum 2-year follow-up, researchers here reported a 1.9% rate of subsequent dislocation after total hip arthroplasty in a contemporary practice and noted 58% of these cases had an acetabular socket position within the Lewinnek safe zone.

    “Most contemporary total hip arthroplasties that dislocate are within the Lewinnek safe zone,” Matthew P. Abdel, MD, said during his presentation at the American Association of Hip and Knee Surgeons Annual Meeting. “Cup position for some patients certainly lies outside this safe zone. Most importantly, new technologies will need better targets to hit prior to them being clinically relevant or economically feasible.”

  • Preterm, low birth-weight babies may need new hips in adulthood

    Researchers from Australia report that low birth weight and preterm birth are linked to increased risk for osteoarthritis (OA)-related hip replacements in adulthood. The findings also indicate that low birth weight and pre-term babies were not at greater risk of knee arthroplasty due to OA as adults.

  • Pacira Pharmaceuticals Inc. announces new data on the use of EXPAREL to treat postsurgical pain following total knee arthroplasty

    Pacira Pharmaceuticals, Inc. has announced results of an independent, physician-initiated study designed to evaluate the difference in postsurgical pain and opioid consumption between patients who received EXPAREL versus a multi-drug analgesic cocktail for pain management following total knee arthroplasty (TKA). The data, presented at the annual meeting of the American Association of Hip and Knee Surgeons (AAHKS), found that patients treated with EXPAREL reported significantly lower patient-perceived pain scores and morphine sulfate equivalence consumption, and reported higher satisfaction with pain control and overall experience, compared with patients who received the multi-drug analgesic cocktail.

  • Acoustic technique developed to detect knee osteoarthritis

    A revolutionary medical technique using sound waves to identify osteoarthritis in the knee has been developed by researchers.

    The UK is leading this new field of health research based on listening to the sounds emitted by the body.

    Microphones are attached to the knees of patients, and the high frequency sound waves emanating from their knees are measured as they stand up. These acoustic emissions are interpreted by computer software to give information about the health of the patient’s knee.
