Clinical experiences with cartilage repair techniques: outcomes, indications, contraindications and rehabilitation

Abstract

Untreated articular cartilage defects may lead to chronic joint degeneration and functional disability. In the past decade, several cartilage repair techniques have emerged for the treatment of cartilage lesions. Among these techniques, mosaicplasty was introduced by the senior author into the clinical practice in 1992. This article does not intend to give a review or a comparison of currently existing surgical techniques which aim to repair symptomatic focal defects; however, it focuses on the procedures used in the everyday practice in the authors’ institute, namely microfracture, mosaicplasty, autologous chondrocyte implantation (ACI), osteochondral allograft transplantation and biodegradable osteochondral scaffolds. It gives a brief summary of these well-described techniques, summarizes the authors’ clinical experience and available data on the clinical outcome, and the rehabilitation protocol following different procedures, with a special emphasis on mosaicplasty.
