<p>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.</p>
