Patella luxation is one of the most frequent knee-joint injuries of adolescence. The cause of the luxation is often not necessarily elicitation by adequate trauma, but rather predisposing factors, such as the patella form or its position in relation to the trochlea appear to be co-responsible. Therapy of the acute primary patella luxation is a matter of controversial discussions.


Between November 1999 and March 2004, arthroscopic-supported medial retinculum suture was performed in our hospital on 78 patients after primary luxation of the patella.. The operation, performed in modification of the technique first described by Yammamoto, and the intraarticular findings are presented in detail.


Osteochondral fragments at the lateral femurcondylus or at the medial patella facette could be found in 56 patients. The mean hospital stay was 3 days, limitation of movement by orthesis was generally required for a period of 4-6 weeks postoperative. In the follow-up of mean 37 months to date, luxations recurred in 7 patients.


This recurrence rate of 8 % is well below the figures cited for conservative therapy of patella luxation in the literature. For the patient, the arthroscopic-supported medial retinaculum suture is a minimally-invasive procedure with good to excellent postoperative results.
