Abstract

Arthritic synovitis is best cured by total removal of the inflamed synovia (equals synovectomy). This can be performed by open chirurgy, by arthroscopy, or by radiosynoviothesis, i.e., injection of (beta) -radiating rare earth metals into the joint cavity. All these procedures are more or less non-quantitative and may lead to a recidive. The idea was to destroy the inflamed synovia by PDT without destruction of the underlying tissue (cartilage and bone). So, the sensitivity of the cartilage-building cells, which can be grown in cell culture, has to be studied.
