Die Behandlung des unikompartimentellen Gelenkknorpelschadens am Knie bietet eine Reihe von Therapiemöglichkeiten. Mit Unterstützung durch einen Algorithmus wird eine Entscheidungshilfe bei der Vorgehensweise in der Behandlung von unikompartimentellen Gelenkknorpelschäden gegeben. Die Korrektur einer Achsabweichung stellt für eine erfolgreiche Therapie eine Grundvoraussetzung dar. Weiterhin spielen die Defektgröße und Kontextfaktoren wie z. B. das Alter und vorrausgegangene Therapien eine wichtige Rolle für die Wahl der geeignetsten operativen Vorgehensweise.


The treatment of unicompartmental cartilage defects offers a large variety of therapeutic options. With help of an algorithm, decision-making for the most suitable treatment approach is supported. Correction of malalignment is key for successful treatment. Defect size, influencing factors such as “age” and prior treatments play an important role in choosing the most appropriate operative treatment option.
