Cartiva Synthetic Cartilage Implant Products Liability Litigation

The causation theory is based on the failure of the hydrogel material (polyvinyl alcohol) used in the Cartiva implant, which often degrades or destabilizes under physiological conditions. This leads to biomechanical mismatch, joint instability, inflammation, and tissue destruction. The implant's material properties cause mechanical degradation, immune responses, and biological reactions that result in persistent pain, joint deterioration, and the need for revision surgeries. The failure mechanisms include material breakdown, inflammatory responses, and biomechanical mismatch, which collectively cause the reported injuries.

Who qualifies

Plaintiffs must have documented exposure to the Cartiva implant and a medical diagnosis of injuries such as pain, joint instability, nerve damage, or implant failure. Injuries should be linked to adverse events following implantation, including failure, subsidence, pain, and the need for revision surgeries. The injuries must be diagnosed by a healthcare professional, and claims are generally filed within a certain timeframe post-implantation, although specific timeframes are not explicitly detailed.
