Biologic Resurfacing of the Ankle and First Metatarsophalangeal Joint: Case Studies with a 2-Year Follow-Up

The goal of biologic resurfacing is to provide a smooth joint surface with a low coefficient of friction, which allows the joint to function with near normal biomechanics, as well as provide intermittent pressure, to the subchondral and cancellous bone. This unique combination often results in the formation of a "neocartilage-like" structure that can reduce pain and restore biomechanics. As well as giving a brief history of cutis arthroplasty, this article describes cases in which the ankle and first metatarsophalangeal joint underwent biologic resurfacing, with a 2-year postoperative follow up.
