1. A method of using a cross-linked hydrogel, said cross-linked hydrogel obtained by a process in which the cross-linked hydrogel is obtained through a reaction step which consists of reacting a hydroxyl function-containing polymer selected from the group consisting of polyvinyl alcohol, polyallyl alcohol, and polyvinylethylene alcohols, with a monomer containing at least two carbon-carbon double bonds selected from the group consisting of bisacrylamides, methylenebisacrylamide, ethylenebisacrylamide, isopropylenebisacrylamide and diallyl urea, in an aqueous basic environment, said method comprising a step of using said hydrogel as an injectable filler for treating a joint tissue deficit.
