Introduction: Recurrent patellar dislocation is a condition in which the patellar surface is not maintained in congruity as it moves along the intercondylar groove of the femur during knee flexion and extension movements. The objectives of this study are to show the distribution of patients with recurrent patellar dislocation according to different sociodemographic variables and to evaluate the outcomes using the Campbell technique. Material and methods: An observational study was conducted in patients with recurrent patellar dislocation from December 2017 to December 2019. Data collection was performed through a review of medical records. The sample consisted of 19 patients, and the system proposed by the authors was used to evaluate the surgical technique. Data processing included the calculation of summary measures for qualitative variables, absolute frequencies, and percentages. Results: The female sex and the age group of 15 to 30 years were the most frequent, healing was poor in two patients, good results were obtained in 84.3% of the operated patients. Conclusions: Females and the 15- to 30-year-old age group predominated, and healing was poor in two patients. Good results were obtained in the operated patients. Although most authors recommend medial patellofemoral ligament repair as the technique of choice or the Insall technique, the Campbell technique yields good results when applied to recurrent patellar dislocations requiring proximal realignment of the extensor mechanism.
