Modified Galeazzi Procedure for Treatment of Habitual Patella Dislocation in Skeletally Immature Patients

ABSTRACT

PURPOSE: The purpose of this study is to elucidate the clinical feature of the hasbitual patella dislocation in the skeletally immature patients and evaluate the result of modified Galeazzi procedure. MATERIAL AND METHODS: From Aug, 1997 to Jan, 2002 we operated 9 knees in 7 patients. Mean age at surgery was 13.3 years. There were 3 males with 3 knees and 4 females with 6 knees. The lateral retinaculum was released and the medial retinaculum was reefed. Patella was tenodesed with semitenidinosus tendon. The operated knees were immobilized with plaster of cast for 3 weeks and progressive range of motion exercise with hinged brace was permitted. RESULTS: Based on the clinical and radiological evaluation, there were improved results. Especially congruence angle was decreased from preoperative +72 degrees to postoperative +20 degrees. There was 1 recurrence that had increased femoral anteversion and 1 arthrofibrosis that had past history of ipsilateral thigh infection. CONCLUSION: Satisfactory clinical results were obtained with modified Galeazzi procedure for treatment of habitual patella dislocation in skeletally immature patient.
