Since March 1983 till August 1984, we have done the laterl retinacular release for subluxation syndrome of the patella in 22 cases. The mean age was 18 years (from 10yrs. to 26yrs.). The tilting angle and the lateral shift of the patella in their skyline view were distinctly improved (p<0.01 significantly).According to the Ficat's criteria, the results at one year after the surgery were excellent in 55% of the cases and good in 45%. At two years after surgery, the results were excellent in 49%, good in 39% and fair in 12%. The resucts became worse between one and two years after operation. The all fair cases had large Q-angle (over 25 degrees), general joint laxity and patella alta.
