[Injuries of the posterior end of the medial meniscus and the posterior oblique ligament. Classification and therapy].

Meniscectomy undoubtedly leads to arthrotic degeneration in the knee joint. This can be proven by X-ray technique. It is especially the resection of the medial meniscus which increases the anteromedial instability of the knee joint. It is important therefore to preserve a meniscus whenever this is possible. The resection or partial resection of a medial meniscus showing a lesion in loco classico is still indicated. If, however, a meniscus is only marginally detached from its fixation to the lig. collaterale mediale posterior a carefully carried out reinsertion of the medial meniscus has proven to be appropriate. It is on one hand the vascular supply of the base of the meniscus which indicates a reinsertion, on the other hand an anteromedial instability of the knee joint can be compensated by a reinsertion.
