Zimmer Holdings is an Indiana-based orthopedics company involved in providing hip and knee solutions including joint and skeletal replacement systems and surgical tools as well as biologics designed to assist in joint replacement surgeries. In April 2014, Zimmer and Biomet announced to come together to provide a joint replacement, bone repair, and dental implant solutions. In June 2015, they started out as Zimmer Biomet and began offering solutions to the musculoskeletal healthcare industry. The hip and knee implant were intended to relieve pain, provide good quality of life to the patients. However, Zimmer lawsuits filed by several individuals claimed the metal-on-metal articulation used in the system resulted in Metallosis, because of the metal grounding on metal as it leads to toxic metal shards being released into the patient's surrounding tissues and bone.
The Food and Drug Administration (FDA) approved Zimmer Durom Acetabular Component (commonly known as Durom Cup) in 2006 for the use of total hip replacement to address the durability and range of motion of the joint. Most of Zimmer Holdings Inc. came to the market after going through the FDA’s 510(k) clearance process. The young patients with more physical lifestyle were targeted and implanted, and it was observed it lead to serious injuries within a short time. The FDA received Zimmer Biomet's clearance notification on October 25, 2018, and granted the clearance on January 24, 2019, for ROSA Knee System. Zimmer Persona knee implant was approved by the FDA in December 2012.
How Does It Work?
During the surgery, the damaged cartilage surfaces at the ends of the femur and tibia are removed along with a small amount of underlying bone. The implants are then placed in the cavity, which recreates the surface of the joint.
The procedure helps relieve pain caused by joint trauma or degenerative disease like osteoarthritis and restores mobility, making walking easier.
