Summary

Chondral and osteochondral lesions as well as bone bruises of the ankle are caused in the most cases by trauma and are localized almost exclusively at the talus. For diagnosis, operative management and follow up, magnetic resonance imaging was useful, which can be further improved by application of intravenous or intraarticullar contrast enhancement (Gadolinium). In adults operative therapy is favored. Due to new techniques, arthroscopy became an important alternative to arthrotomy. According to the stage of the disease, drilling or curettage, removal or fixation of the fragment, autologous bone transplantation or osteochondral graft can be performed. All procedures can be managed arthroscopically.

Zusammenfassung

Chondrale und osteochondrale Läsionen sowie „bone bruises“ treten meist infolge einer Verletzung auf und betreffen am oberen Sprunggelenk (OSG) fast ausschließlich den Talus. In der Diagnostik, zur Therapieplanung sowie Verlaufsbeobachtung bewährt sich die Magnetresonanztomographie (MRT), deren Sensitivität durch intravenöse oder intraartikuläre Kontrastmittelgabe (Gadolinium) noch weiter verbessert wird. Im Erwachsenenalter wird das operative Vorgehen bevorzugt. Durch Entwicklung neuer Techniken stellt die arthroskopische Therapie inzwischen eine ernsthafte Alternative zur Arthrotomie dar. Stadiengerecht wird entweder eine retro-/anterograde Anbohrung, Dissekatentfernung/-refixierung, autologe Spongiosaplastik oder Knorpel-Knochen-Transplantation durchgeführt. Alle Techniken können arthroskopisch erfolgen.
