Donor site morbidity after articular cartilage repair procedures: a review.

In order to perform an Osteochondral Autologous Transplantation (OAT) or an Autologous Chondrocyte Implantation (ACI), the integrity of healthy intact articular cartilage at a second location needs to be violated. This creates the possibility for donor site morbidity. Only recently have any publications addressed this issue.

High inter-specimen variability of baseline data for the tibio-talar contact area.

Background: The tibio-talar contact area has been widely investigated to monitor biomechanical changes due to articular incongruities or an altered loading. This study aims to investigate for the first time in a systematic way the extent of the inter-specimen variability of the tibio-talar contact area, and its repercussions when analyzing data concerning this parameter.

Methods: Ten specimens were loaded to record the tibio-talar contact characteristics by use of pressure sensitive film.
