Abstract

Our experience with recurrent dislocation of the patella on ten knees in eight patients seen at Seoul National University Hospital during the last 2 years and eight months is reported. Five were female and three male. The age ranged from seven to 27 years. In four of the patients the onset was attributable to a definite history of trauma, while in one patient the dislocation was considered due to developmental anomalies and in another it was clearly congenital Still another patient had a progressively short limb due to premature closure of the distal femoral epiphysis with accompanying flexion-valgus deformity of the knee, presumably caused by an unrecognized infection during early childhood One adolescent girl had bilateral knock knees. The knock knees were treated successfully by supracondylar osteotomy and one post-traumatic knee by classical Roux-Goldthwait procedure with equally excellent result, The rest were treated by Greens vastus medialis transfer with division of the iliotibial band or reefing of the medial joint capsule when necessary. In one knee dislocation recurred, probably due to avulsion of the transferred vastus, and two knees had residual subluxation and limitation of flexion. The results on the remaining seven knees were excellent.
