The traumatic luxation of the patella is the most frequent cause of osteochondral or chondral fragments in the knee joint A precise case history most often provides the necessary reference concerning the occurrence of a luxation The hemarthrosis and the painful reduction of the mobility after a closed spontaneous reposition hint towards the possibility of a chondral or osteochondral fracture requiring an emergency arthrotomy.
If large chondral or osteochondral fragments are found intraoperatively, then a refixation of these fragments should be attempted The following methods can be used: a fixation with ASIF-mini screws a fixation with Smillie pins a fixation with cortical nails or the removal. We will report about these methods being used at our clinic and will discuss the results.
Many differing surgical methods are available for a causative treatment of the patella luxation The application of the necessary method is dependent upon the age of the patient as well as on the pathologicalanatomical circumstances The differing methods will be described.
The successful results of a refixation using a fibrin glue cannot be judged finally.

Die traumatische Patellaluxation ist die hiufigste Ursache osteochondraler oder chondraler Fragmente im Kniegelenksbereich Die Anamnese gibt meist einen Hinweis auf eine stattgefundene Luxation. Das Hiimarthros und die schmerzhafte Bewegungseinschrankung nach geschlossener Reposition lenken den Verdacht auf eine chondrale oder osteochondrale Frak-
