The 3-in-1 procedure for recurrent dislocation of the patella in skeletally immature XXXX and adolescents.

@entity1 @entity8043
BACKGROUND: Recurrent @entity8043 are common injuries in @entity1 and adolescents. The subjective and functional results of soft tissue surgical management in a population that was skeletally immature at the time of surgery have not been reported. HYPOTHESIS: The 3-in-1 procedure is an effective treatment for recurrent @entity8043 in skeletally immature @entity1 . STUDY DESIGN: Case series; Level of evidence, 4. METHODS: Twenty-five skeletally immature @entity1 (age at operation, 13.5 +/- 3.8 years) who were practicing sports and suffering from recurrent @entity8043 were included in the study and followed until skeletal maturation. Clinical evaluation included the modified Cincinnati rating system and the Kujala score, anthropometry, plain radiography, and isokinetic dynamometry. RESULTS: The average follow-up was 3.8 years (range, 2.5-6 years). The mean modified Cincinnati score increased from 51.7 +/- 12.6 preoperatively to 94.3 +/- 10.8 (P < .02), while the mean Kujala scores increased from 52.4 +/- 12.7 preoperatively to 93.8 +/- 14.2 (P < .02). The Insall-Salvati index remained essentially unchanged, being 1.04 +/- 0.2 preoperatively and 1.02 +/- 0.3 at latest follow-up. Significant differences were found between the operated and the contralateral limb in the various isokinetic strength variables at all angular velocities measured at the latest follow-up (.05 < P < .0042). CONCLUSION: The 3-in-1 procedure is a safe, reliable management option for recurrent @entity8043 in skeletally immature @entity1 . Side-to-side differences in isokinetic strength and in anthropometric indices persist despite subjective success of the procedure.
