Progressive lateral femoral condyle lengthening in total knee arthroplasty produces dose‐dependent increases in patellofemoral joint loading and alters patellar tracking

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To examine the biomechanical effects of progressive lateral femoral condyle lengthening on patellofemoral joint (PFJ) kinematics and kinetics following total knee arthroplasty (TKA), and to determine whether lateral condyle distalisation produces measurable, dose‐dependent alterations in PFJ loading and patellar tracking.

Magnetic resonance imaging‐based axial‐plane analysis of lower extremity torsion with dedicated 3D planning software is reliable and efficient

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The reliability and efficiency of a dedicated 3D planning software were evaluated for magnetic resonance imaging (MRI)‐based measurement of femoral torsion, tibial torsion, knee version and whole‐lower extremity torsion compared with manual assessment.

Reduced patella medialization in valgus and varus knees using a KA‐optimized femoral component in kinematically aligned TKA

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Patellofemoral complications after total knee arthroplasty (TKA) are linked to femoral component design and trochlear alignment. This study compared the effects of a kinematically aligned (KA)‐optimized femoral component versus a standard design on patellofemoral kinematics, contact mechanics and quadriceps function, using native knee ...

Roux-Goldthwait and Medial Patellofemoral Ligament Reconstruction for Patella Realignment in the Skeletally Immature Patient

Arthroscopy Techniques, 2019
Surgical management of patellofemoral instability is technically challenging in skeletally immature patients. Special considerations in this population include activity and sports limitations, recurrence rate, risk of long-term injury to patellofemoral ...

Current concepts in isolated and combined injuries of the medial collateral ligament complex—Part I: Anatomy, biomechanics, clinical and radiological examination of the medial collateral ligament of the knee

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Injuries involving the medial collateral ligament (MCL), or combined injuries to both the anterior cruciate ligament (ACL) and MCL, are common and present considerable diagnostic and therapeutic challenges. Better understanding of MCL anatomy and biomechanics, especially in combined ACL–MCL injuries, has driven the need for updated clinical ...

Low graft re‐rupture rate after primary ACL reconstruction using a modified MacIntosh iliotibial band technique with gracilis augmentation: Minimum 6‐year follow‐up

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Combined intra‐ and extra‐articular anterior cruciate ligament (ACL) reconstruction has gained renewed interest to improve rotational stability and reduce graft failure. This study evaluated graft re‐rupture rates, functional and return‐to‐sport (RTS) outcomes at a minimum 6‐year follow‐up after primary reconstruction using a modified ...

Detection of previous knee injuries using lower limb‐worn inertial measurement units: A cross‐sectional machine‐learning study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Previous knee injury increases the risk of subsequent injury, even after functional recovery, yet residual gait, running or load alterations often go undetected in routine assessment. Wearable inertial measurement units (IMUs) may enable scalable detection of such alterations outside laboratory settings.

Patellofemoral instability in skeletally immature patients

Porto Biomedical Journal, 2017
A decade after patellofemoral ligament reconstruction results remains satisfactory.It is a good option for patellar instability treatment in children.Patients with trochlear dysplasia benefit from trochleoplasty after physeal closure.Patellofemoral instability is a common cause of knee disability.
