Abstract

Introduction: Instability of the patellofemoral joint may manifest as acute patellar dislocation, recurrent
patellar dislocation or subluxation, habitual patellar dislocation or chronic patellar dislocation. Habitual
dislocation of patella is a condition where the patella dislocates whenever the knee is flexed and
spontaneously relocates with extension of the knee. We conducted this study to know the radiological
outcome following proximal realignment procedure (Campbell procedure) for habitual dislocation of
patella.
Materials and Methods: The study was conducted from June 2017 to January 2019 with a minimum
follow up of 6 months and a maximum follow up of 2 years.
Inclusion Criteria: All patients with habitual patellar dislocation, age between 5 to 40 years.
Exclusion Criteria: Patient age less than 5 years and aged above > 40 years, past history of knee surgery,
acute patellar dislocation and knee effusions. Radiological assessment was done by measuring sulcus angle
and congruence angle.
Conclusion: we conclude that following proximal realignment procedure (Campbell procedure) for
habitual dislocation of patella radiological parameters were brought back to normal. There were no
significant changes in sulcus angle. Congruence angle was brought back to normal, which was statistically
significant (p<0>

Keywords: Habitual dislocation of patella, Campbell procedure, Sulcus angle, Congruence angle.
