Total ankle replacement has become an increasingly recommended treatment option for endstage ankle osteoarthritis over the last decades. As a result of this progress, a large variety of implant systems exist.
The Hintermann Series H3 Total Ankle Replacement System (H3) is a three-piece, mobile-bearing implant. The H3 is indicated for use as a non-cemented implant to replace a painful arthritic ankle joint due to primary osteoarthritis, post-traumatic osteoarthritis, or arthritis secondary to inflammatory disease.
The purpose of this study is to investigate long-term (up to 5 years) how the H3 implant is performing, collect information about the device through x-rays of the joint, document any complications from the device implant, see how the device affects patient quality of life.
