The American College of Rheumatologists (ACR), in partnership with AAHKS, is developing a new clinical practice guideline for perioperative management of rheumatic disease medications in total joint arthroplasty of the hip and knee. The guideline will be developed primarily for orthopaedic surgeons and rheumatologists who care for patients undergoing total joint arthroplasty, but may also be used by other providers who care for these patients. AAHKS encourages members and others to comment on the project plan that will be used in this guideline development by March 24, 2016. Visit the ACR website to view the plan and to comment.
