Is Diagnostic Arthroscopy at the Time of Medial Patellofemoral Ligament Reconstruction Necessary?

Orthopaedic Journal of Sports Medicine, 2020
Background: Although medial patellofemoral ligament (MPFL) reconstruction is well described for patellar instability, the utility of arthroscopy at the time of stabilization has not been fully defined. Purpose: To determine whether diagnostic arthroscopy

Over Half of Patients Progress to Cartilage Restoration After Initial Cartilage Biopsy in a Military Population

Arthroscopy, Sports Medicine, and Rehabilitation, EarlyView.
Purpose To evaluate the rate of matrix‐induced autologous chondrocyte implantation (MACI) after cartilage biopsy in a military population. Methods A retrospective review was conducted of all patients who underwent a cartilage biopsy at 2 large regional military health centers between January 2021 and May 2023.

Magnetic Resonance Imaging Assessment of the Femoral Tunnel Position in Medial Patellofemoral Ligament Reconstruction

Journal of Orthopaedics, Trauma and Rehabilitation, 2016
Background/Purpose: Correct femoral tunnel position in medial patellofemoral ligament (MPFL) reconstruction is essential to maintain proper biomechanics of the patellofemoral joint throughout the range of movement.

Predictors of Graft Failure After Primary Medial Patellofemoral Ligament Reconstruction

Orthopaedic Journal of Sports Medicine, 2022
Background: The tibiofemoral rotation angle has been found to be higher in patients with recurrent patellar dislocations (RPDs) than in healthy people; however, little is known about the clinical significance of this finding.

Patients undergoing medial patellofemoral ligament reconstruction return to sport sooner and at a higher level than those undergoing concomitant tibial tubercle osteotomy

Journal of Experimental Orthopaedics
Purpose The purpose of the study was to compare time to return to sport between patients undergoing isolated medial patellofemoral ligament reconstruction (MPFL‐R) and patients undergoing MPFL‐R and concomitant TTO (MPFL‐TTO) for recurrent patellofemoral

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
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.

Medial Patellofemoral Ligament Reconstruction with and without Tibial Tubercle Osteotomy

Orthopaedic Journal of Sports Medicine, 2019
Objectives: The medial patellofemoral ligament (MPFL) is the primary soft-tissue restraint against lateral patellar displacement. Surgery to address MPFL incompetence is the current gold standard for recurrent patellofemoral instability.
