Lesions of the talar cartilage are extremely difficult to diagnose clinically or roentgenologically. Often they are masked by accompanying lesions of the bone or the capsular ligaments, so that arthrotomy will be necessary to obtain information on the condition of the cartilage. Reconstruction of the articular surface is a most important prerequisite für restoring the ability of the cartilage to cope with physiological load. Hence, the aim of the treatment is the replantation of abraded cartilaginous fragments. The use of concentrated fibrinogen as a biological tissue adhesive has been gaining in importance as an alternative to the methods of refixation practised so far. The actual process of gluing is technically simple. 7 patients in whom gluing of the cartilage at the talus had been performed, remained free from complaints for a follow-up period of three years.
