Abstract

Various surgical methods exist for the treatment of focal chondral and osteochondral defects of weight-bearing articular surfaces. Traditional resurfacing techniques provide reparative fibrocartilage coverage of the lesion with poor biomechanical properties and suboptimal clinical outcome. Recent advances in treatment options including osteochondral allografts aim to provide hyaline or hyaline-like repair for articular defects. Although previous publications on autogenous osteochondral transplantation reported long-term hyaline cartilage survival on the transplanted osteochondral block [3, 6, 23, 26], clinical use of single-block osteochondral transfer had been restricted by limited donor-site availability. Also, use of large grafts can cause incongruity at the recipient site, which permanently alters the biomechanics of the joint [5, 7, 9-12]. Our preclinical animal studies performed between 1991 and 1992 showed that the use of small-sized multiple cylindrical grafts, rather than a single large block graft, allows more tissue to be transplanted while preserving donor-site integrity and the mosaic-like implanting fashion permits progressive contouring of the new surface [13, 15].
