Frühe Ergebnisse nach minimalinvasiver operativer Versorgung von frischen und chronisch rezidivierenden Kniescheibenluxationen bei jungen Erwachsenen

Abstract

The aim of this study is to answer the question whether a modified, minimally invasive Madigan/Insall operation is an appropriate treatment for acute or recurrent patellar dislocations. Between January 1, 2002 and June 30, 2005 a total of 56 patients with acute and chronic patellar dislocations were operated. The patients underwent follow-up examinations between 8 and 19 months postoperatively. Their subjective satisfaction with the result was assessed (according to Larsen and Lauridsen). 34 of the operated patients (94%) were available for follow-up. 28 of them had a good, 3 a satisfactory and 3 a poor subjective result. No re-dislocation occurred. A large number of operative techniques has been described for the treatment of acute and recurrent patellar dislocation. In our opinion, a minimally invasive operative technique, in which the patella is actively stabilized by the vastus medialis muscle, has decisive advantages compared to conventional techniques.
