title: Pes anserinus transposition for patellar dislocations. Long-term follow-up results.
abstract: Transposition of part of the pes anserinus was used to treat 96 knees in 78 patients with recurrent, habitual or permanent dislocations of the patella. The knees with habitual (48) and permanent (27) dislocations also had extensive release of superolateral contracture. The patients were reviewed at an average follow-up of 9 years 8 months. The medial stability of the patella had been improved in all the cases. There were no recurrences in 21 knees with recurrent dislocations. There were four recurrences (5.3%) in knees with habitual and permanent dislocations due to inadequate release of the superolateral contracture and incorrect transfer of the whole of the pes anserinus. Correction of these technical errors prevented further recurrence in all four cases.
