JUPITER 4.0 - Risk Factors for Failure of Isolated Medial Patellofemoral Ligament Reconstruction

NCT06883396 · Status: RECRUITING · Type: OBSERVATIONAL · Enrollment: 850

Last updated 2026-02-13

No results posted yet for this study

Summary

The goal of this observational study is to learn about the outcomes of medial patellofemoral ligament (MPFL) reconstruction for the treatment of recurrent patellar instability. The main questions it aims to answer are:

* What are the risk factors for recurrent patellar instability after MPFL reconstruction?
* What functional outcomes do patients report after MPFL reconstruction?

Participants undergoing MPFL reconstruction will answer survey questions about their knee and activity level 1 year and 2 years after surgery.

Conditions

  • Patellar Dislocation, Recurrent
  • Patellar Dislocation
  • Patellar Instability
  • Patellofemoral Dislocation
  • Patellofemoral Joint Dislocation
  • Patellofemoral Disorder

Interventions

PROCEDURE

Medial Patellofemoral Ligament (MPFL) Reconstruction

For the purposes of this study, isolated MPFL reconstruction is defined as MPFL reconstruction with a tendon graft, with or without additional soft tissue procedure(s) including lateral retinacular lengthening or release, patellofemoral chondroplasty and/or cartilage restoration. No patient in the study will receive a bony realignment procedure to treat patellar instability.
