Overview

Case series identifies risk factors predicting future contralateral patellar instability, suggesting implications for patient management.

Key Points

  • This study aims to identify risk factors for future contralateral patellar instability in individuals who have undergone MPFL reconstruction.
  • Analyzed a hospital database from 2012-2022 for patients who had MPFL reconstruction.
  • Recorded patient characteristics including age, sex, BMI, and joint hypermobility.
  • Assessed four anatomic risk factors through MRI of the ipsilateral knee.
  • Applied multivariable backward conditional logistic regression analysis to pinpoint risk factors.
  • Out of 380 knees analyzed, 34.2% exhibited future contralateral patellar instability.
  • Key predictive factors include skeletal immaturity, generalized joint hypermobility, and recurrent ipsilateral patellar instability.
  • Risk of contralateral instability varies from 9.2% with no risk factors to 77.8% with all five risk factors present.
