US Patent 7591820 Retrograde osteochondral autograft transfer system

A retrograde osteochondral autograft transfer system that ensures that grafted healthy bone is implanted into the recipient site in a retrograde manner as opposed to a conventional anterior manner, so that the grafted healthy bone is flush with the bone surface of the recipient size. The retrograde osteochondral autograft transfer system of the present invention employs two identically-sized harvesters which are aligned with each other for transfer and reversal of a harvested osteochondral core, such that the core can be introduced into the recipient site through a tunnel leading to the recipient site, with an articular surface of the core advanced in a leading position.
