Poster 244: Pain Catastrophizing in Patellar Instability Patients Undergoing MPFL Reconstruction

Orthopaedic Journal of Sports Medicine | 2022 | Athan Zavras, Nicholas Trasolini, Justin Walsh, Adam Yanke

Objectives: Pain catastrophizing was established as a way to measure patient perception and response to pain, as represented by three subscores: rumination, magnification, and helplessness. Prior clinical studies have demonstrated the close relationship between pain catastrophizing and persistent postoperative pain after total knee arthroplasty. Among patellofemoral instability...

Paper 54: MPFL Repair has a Higher Failure Rate at Long-term Follow-up compared to MPFL Reconstruction for Recurrent Patellar Instability

Orthopaedic Journal of Sports Medicine | 2022 | Ryan Wilbur, Bryant Song, Jory Wasserburger, Christopher Camp

Objectives: The medial patellofemoral ligament (MPFL) is the primary soft tissue restraint to lateral patellar translation and is often disrupted with a lateral patellar dislocation. Surgical management for recurrent patellar instability focuses on restoring MPFL function with repair or reconstruction techniques. Recent studies have favored reconstruction over repair, but no lo...

Return To Sport Following Stabilization Surgery For Recurrent Patellar Instability In Patients Undergoing Isolated Mpfll Reconstruction Vs. Combined Mpfl Reconstruction And Tibial Tubercle Osteotomy

Orthopaedic Journal of Sports Medicine | 2020 | Stephanie Joelle Swensen, Joseph Nguyen, William A. Marmor, Simone Gruber

Objectives: Acute patellar instability is a common and disabling injury among young athletes and the risk of recurrence is as high as 80% in certain populations. The essential lesion of lateral patellar dislocations is MPFL rupture. However, bony risk factors for dislocation have also been identified, including patella alta, trochlear dysplasia, and a lateralized tibial tubercl...

MPFL GRAFT TENSIONING TO TREAT PATELLAR INSTABILITY RELATED TO PATELLA ALTA: DYNAMIC SIMULATION

Orthopaedic Journal of Sports Medicine | 2020 | Travis Jones, Kerwyn C. Jones, John J. Elias

Background: Medial patellofemoral ligament (MPFL) reconstruction is a popular treatment for lateral patellar instability. For knees with patella alta, however, tibial tuberosity distalization is the most common approach due to concerns about graft tensioning. A MPFL graft is tensioned intra-operatively to prevent lateral subluxation without over-constraining the patella by allo...

Short Oblique Patellar Tunnels for Patellar Fixation Do Not Increase Fracture Risk in MPFL Reconstruction: A Retrospective Cohort Study

Orthopaedic Journal of Sports Medicine | 2020 | Milos Lesevic, Matthew Deasey, Zachary Burnett, David Diduch

Objectives: The current standard of care for recurrent patellar instability is reconstruction of the medial patellofemoral ligament (MPFL), the primary soft tissue constraint to lateral subluxation of the patella. Historically, transpatellar bone tunnels have been associated with increased rates of patella fracture. To avoid this dreaded outcome, many surgeons now employ suture...
