title: [Comparison of patellar dislocation recurrence in patients ages 9 to 16 years treated surgically with the green technique versus an arthroscopic approach].
abstract: OBJECTIVE
  To report the patellar dislocation recurrence in patients ages 9 to 16 years treated surgically with the Green technique or an arthroscopic approach.
  
  
  METHODS
  A prospective, longitudinal study was conducted with patients ages 9 to 16 years who presented at the pediatric orthopedics and arthroscopy service at IMSS "Lomas Verdes" UMAE Orthopedics and Traumatology Hospital with a diagnosis of patellar dislocation from January 1st 2003 to December 31st 2006. The patellar dislocation recurrences were recorded.
  
  
  RESULTS
  Twenty patients and 24 knees were included; 13 females and 7 males; mean age was 14.3 years +/- 1.75. The dislocations prior to surgical treatment occurred at a mean of 5.5 +/- 2.57 dislocation events, with a range of 2 to 10 events. As regards the side involved, 40% had involvement of the left side, 40% of the right side, with 8 patients each, and 20% were bilateral dislocations. No significant differences were found in the clinical course of the patients treated with the Green technique compared with the arthroscopic surgery group (p = 0.371).
  
  
  CONCLUSIONS
  The number of dislocation recurrences after the surgical procedure was not related with the age, gender, number of prior dislocations or surgical technique. No significant difference was found between both groups.
