DePuy Synthes is one of the orthopedic franchise acquired by Johnson and Johnson in 1998 and is involved in manufacturing, designing, marketing products for repairing, reconstructing, correcting, treating various traumatic skeletal damages, bone fractures, and joint deformities.
DePuy Attune Knee System is one of the well-known products used for Total Knee Replacement Prosthesis of DePuy Synthes. Posterior Stabilized (PS) Femoral Component and PS Fixed Bearing Inserts are two parts of DePuy Attune Knee System, which was approved by FDA using the 510k process. It was believed that Attune Knee was one of the largest development catering needs of patients, surgeons until gradually complaints started popping up.
Some instances like the loosening of implants and the entire knee becoming unstable were found which proved that the device is defectively designed. The only way to manage these failures was revision surgery which was painful and all the more troublesome to patients. The concern was later investigated and it became evident that the surface of these devices was very smooth so the surgical glue wasn't able to hold the joint in place.
