Metal-on-Metal Hip Replacement parts -The FDA has ordered a review of all metal-on-metal hip implants due to mounting patient complaints. Problems with the metal-on-metal devices include loosening, fracturing and dislocating of the device caused by inflammation in the joint space. We are investigating all cases involving metal-on-metal hip implants, including the DePuy Orthopaedics ASR XL Acetabular System and the DePuyASR Hip Resurfacing System, recalled in August 2010; the Smith & Nephew R3 Acetabular System, recalled in June 2012; the Stryker Rejuvenate and ABG ll modular-neck stems, recalled in July 2012; the Depuy pinnacle, the Zimmer Durom Cup, the Wright Conserve, and the Biomet M2A and M2A-Magnum hip replacement systems, which have not been recalled. Reported problems include pain, swelling and problems walking.
Patients with hip and/or knee replacement failure have reported the following problem(s):
- Breakage, mainly metal breaks from constant weight-bearing stress
- Fractures typically near the artificial joint
- Loosening of the attachment between the bone and artificial device, both in cemented and un-cemented artifcial joints
- Painful stiffness and infection due to loosening of the attachment between device and bone
- Instability when the artificial joint dislocates
- Wear and tear on plastic parts
