Implication

Cohort study compares redislocation rates and knee function in children treated with brace or MPFL surgery, suggesting follow-up is essential.

Key Points

  • To compare redislocation rates and knee function in pediatric patients treated for first-time patellar dislocation.
  • 10-year follow-up of 74 participants from a randomized controlled trial
  • Primary outcomes assessed included redislocation rates and subsequent knee surgeries
  • Subjective knee function measured using KOOS-Child, Kujala, and Tegner scores.
  • KB group had an overall redislocation rate of 80% compared to 62% for MPFL repair (P = .175)
  • 45% of KB patients and 54% of MPFL patients with redislocation underwent additional surgery
  • Functional scores were similar between groups, but those with redislocation had significantly lower KOOS-Pain and Quality of Life scores.
