Pediatric and Adolescent Patellar Instability

Overview

About this study

This is a multi-center, randomized controlled clinical trial, the purpose of which is to determine if skeletally immature patients who undergo medial patellofemoral ligament (MPFL) reconstruction have lower rates of recurrent instability compared to those treated non-operatively. The MPFL is a ligament that stabilizes the kneecap, and maintains its proper position in the groove on the femur (thighbone). Instability refers to a situation in which the kneecap moves out of place, or dislocates. When instability is recurrent, it occurs more than once in the same knee.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria: 

  • Must be skeletally immature, still growing
  • Must be first-time dislocators, meaning have had only one episode of patellar instability, during which they dislocated their patella (kneecap)

Exclusion Criteria

  • Has had more than one episode of patellofemoral instability
  • Has had prior patellofemoral surgery on the knee of interest
  • Has large cartilage tears in the knee and will undergo stabilization of the patellofemoral joint (MPFL reconstruction) as per standard of care
