The economics of new age arthroplasty: can we afford it?
New technology in joint replacement design and materials adds cost that must be documented by improved outcomes. This is not always the case as the recent metal/metal data has shown. The current economics of arthroplasty have put increasing financial pressure on hospitals and will progress under new health care legislation. New technology must be cost-effective and this will be increasingly difficult in an era of outstanding long-term results with current designs. Cost may necessitate less expensive alternatives, eg, generic implants, in arthroplasty patients. Joint replacement surgery has evolved over the past 4 decades into a highly successful surgical procedure. Earlier designs and materials that demonstrated inferior functional and long-term results have disappeared in a Darwinian fashion. Through this evolutionary process many of the current designs have proven efficacy and durability. Current outcome data indicates that hip and knee designs demonstrate 90% to 95% success rates at 15-year follow-up. Technologic advances are necessary to improve implant design and materials, however, only in an environment of reduced reimbursement to hospitals can the increase cost be justified.
