Hip and Knee Replacement Implants Quality Questionable
A recently published study indicates that many innovative new implants may actually have worse durability and safety qualities than previous models. The study claims that newer models do not necessarily have prominent improvements over older generations of the same model.
About the Hip and Knee Implant Study
The researchers of the study, reacting to the recent high-profile recalls and lawsuits associated with hip and knee implants, navigated their way through comparative studies of several different devices used in hip replacements, including ceramic-on-ceramic bearings, modular femoral necks, and uncemented monoblock cups.
They also examined previous studies on devices used in the two most common knee replacement procedures: high flexion knee replacement and gender specific knee replacement.
The study collected nearly 120 studies including data on more than 15,380 next-generation and older implants used in roughly 13,160 patients, concluding that none of the more contemporary implants offered any significant advantage compared with older generations.

Johnson and Johnson recently recalled its DePuy hip replacement implant after finally admitting it had a 40% failure rate in patients. It has already failed in thousands of patients. It is expected to fail in many more patients over time
