Simultaneous Medial and Lateral Patellofemoral Ligament Reconstruction for Combined Medial and Lateral Patellar Subluxation

Arthroscopy Techniques, 2014
Medial patellar subluxation (MPS) is a disabling, often iatrogenic patellar instability due to previous lateral release for patellar instability. Lateral release destabilizes the patella on the lateral side, worsening the initial lateral instability and ...

Isolated medial patellofemoral ligament reconstruction for recurrent patellofemoral instability: analysis of outcomes and risk factors

Journal of Orthopaedic Surgery and Research, 2021
Background The medial patellofemoral ligament (MPFL) is always damaged after patellar dislocation. In selected patients, MPFL reconstruction is necessary to restore a correct patellar tracking. Despite the large number of different techniques reported to

Posterior cruciate ligament involvement leads to inferior outcomes in multiligament knee injuries involving the medial collateral ligament: A systematic review and meta‐analysis

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Multiligament knee injuries (MLKIs) involving the medial collateral ligament (MCL) present unique challenges in surgical management and postoperative rehabilitation. This systematic review and meta‐analysis aimed to evaluate postoperative patient‐reported outcomes in patients with MCL‐involved MLKIs, with a minimum follow‐up of 2 years.

Underestimation of tibial tuberosity–trochlear groove distance in conventional knee magnetic resonance imaging compared to full‐extension imaging

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To assess the effect of the knee flexion on the tibial tuberosity–trochlear groove (TT–TG) distance measurement by comparing conventional and whole‐leg rotational magnetic resonance imaging (MRI). Methods This retrospective cohort study included 45 patients with patellar dislocations who had undergone both conventional knee MRI with ...

A Case of Patellar Instability and Lateral Facet Cartilage Defect

Video Journal of Sports Medicine, 2022
Background: Concomitant cartilage injury is commonly associated with patellofemoral instability. While nonoperative treatment remains the gold standard for first time dislocators, there has been an increased trend toward addressing patellar instability ...

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 ...

Quadriceps malalignment is strongly associated with recurrent patellofemoral instability in native knees

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Patellofemoral instability (PFI) has been associated with multiple anatomical risk factors. The recent development of accurate quadriceps muscle measurements using three‐dimensional imaging techniques have demonstrated that quadriceps alignment is highly variable and frequently leads to a lateralised force vector on the patella.

Persistent magnetic resonance imaging‐derived static anterior tibial translation after anterior cruciate ligament reconstruction is associated with elevated cartilage T2 relaxation times but not serum biomarkers

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Persistent, static anterior tibial translation (sATT) alterations following anterior cruciate ligament reconstruction (ACLR) may influence cartilage health. T2 relaxation times and serum biomarkers of cartilage degradation/bone resorption provide insight into osteoarthritis development.
