Articular cartilage repair and regeneration is a poorly understood yet clinically important field of study. While cartilage defect resurfacing has been tried both by biological and non-biological materials, yet a satisfactory solution has not been attained. We present a series of 35 experimentally produced defects resurfaced with autologous periosteum in rabbits. The results of such resurfacing showed that unresurfaced defects did the poorest while those resurfaced with periosteum with its cambium layer facing the joint looked closer to normal articular surface. The regenerated cartilage was microscopically similar to original cartilage but of less durability.
