title: The Science Behind Wear Testing for Great Toe Implants for Hallux Rigidus.
abstract: Various methods of repairing damaged articular cartilage surfaces have been proposed and a variety of implant materials have been tried in an attempt to decrease pain and improve function after cartilage repair. The hydrogel made of polyvinyl alcohol and saline is a unique material used as an implant in the great toe for advanced stage arthritis.
