Patient-Individualized Identification of Medial Patellofemoral Ligament Attachment Site to Femur Using “CLASS” MRI Sequences

JBJS Open Access, 2023
Background:. Malposition of the femoral tunnel during medial patellofemoral ligament (MPFL) reconstruction may increase the risk of recurrence of patellar dislocation due to isometric changes during flexion and extension.

Adding lateral retinacular release to medial patellofemoral ligament reconstruction reconstruction has no effect on patellar height: A prospective randomised controlled trial

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To evaluate the effect of medial patellofemoral ligament (MPFL) reconstruction with or without lateral retinacular release (LRR) on patellar height in patients with recurrent patellar dislocation (RPD). It was hypothesised that the addition of LRR would not significantly modify patellar height compared with isolated MPFL reconstruction.

Adding Lateral Retinacular Release to Medial Patellofemoral Ligament Reconstruction Fails to Demonstrate Clinical Benefit Compared With Isolated Medial Patellofemoral Ligament Reconstruction

Arthroscopy, Sports Medicine, and Rehabilitation
Purpose: To compare functional outcomes and failure rates between medial patellofemoral ligament (MPFL) reconstructions with and without lateral retinacular release (LRR) at minimum 1-year follow up. Methods: A retrospective review identified consecutive

CLASS‐MRI validates patient‐specific ACL footprints across variable fluoroscopic C‐arm positioning: A cadaveric study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The aim of this study was (1) to investigate the accuracy of identifying the femoral and tibial anterior cruciate ligament (ACL) footprints (FPs) using the Compressed Lateral and Anteroposterior Anatomical Systematic Sequences (CLASS) method compared to the to the gold standard (anatomical dissection with direct FP marking, referred to

Graft choice for isolated MPFL reconstruction: gracilis versus semitendinosus

, 2020
Introduction!#!After the first patellar dislocation, most patients report damage of the medio-patellofemoral ligament (MPFL) and surgical reconstruction is required.

Collagen‐membrane‐covered matrix‐associated chondrocyte implantation improves safety over periosteum‐covered MACI for large knee cartilage defects: A real‐world data analysis in the registry study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This registry study aimed to evaluate the safety and effectiveness of collagen membrane‐covered matrix‐associated autologous chondrocyte implantation (cMACI) versus periosteum‐covered MACI (pMACI) for large knee cartilage defects (Outerbridge III–IV, ≥4 cm²) in the femorotibial and/or patellofemoral joints with a minimum 2‐year follow ...

MRI but not arthroscopy accurately diagnoses femoral MPFL injury in first-time patellar dislocations [PDF]

, 2011
The purpose of this study was to investigate whether the femoral part of the medial patellofemoral ligament (MPFL) and its injury can be accurately assessed by standard knee arthroscopy in first-time patellar dislocations or whether preoperative MRI is ...

Biomechanical and Functional Outcomes After Medial Patellofemoral Ligament Reconstruction: A Pilot Study

Orthopaedic Journal of Sports Medicine, 2019
Background: Previous studies have acknowledged the medial patellofemoral ligament (MPFL) as the primary stabilizer of the patella, preventing lateral displacement.

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

Orthopaedic Journal of Sports Medicine, 2020
Background: Large (4.5 mm) and/or transpatellar bone tunnels have been associated with patellar fracture after medial patellofemoral ligament (MPFL) reconstruction. To avoid this outcome, many surgeons now employ suture anchors to affix the MPFL graft to
