[Micro-modified Fulkerson osteotomy for the treatment of habituation patellar dislocation].
OBJECTIVE
To evaluate clinical effect of micro-modified Fulkerson osteotomy under arthroscope in treating habituation patellar dislocation.


METHODS
Twenty patients of habituation patellar dislocation (25 knees) were treated by the medial retinaculum plication, lateral retinaculum releasing and modified Fulkerson osteotomy (tibial tubercle anteromedial transfer) under arthroscope. There were 5 males and 15 females with the age from 16- to 28-years-old (average of 21 years). The subjective symptoms and the joint function were evaluated according to Lysholm and Tegner scoring system.


RESULTS
All the patients were followed up from 12 to 36 months with an average of 24 months. No found redislocation in the patients. The Lysholm score was 54.4 +/- 12.1 and 87.7 +/- 9.6 (t=2.33, P<0.05) before and after surgery respectively. The Tegner score was 2.8 +/- 0.8 and 5.1 +/- 1.3 (t=4.36, P<0.01) before and after surgery respectively.


CONCLUSIONS
Micro-modified Fulkerson osteotomy under arthroscope for the treatment of habituation patellar dislocation is a rescheduled in extend knee equipment, its advantages including affirmative effect, minor damage, quick rehabilitation, fewer complications and lower rate of recurrence after operation.
