Bargmann Type Systems for the Generalization of Toda Lattices

Journal of Applied Mathematics, 2014
Under a constraint between the potentials and eigenfunctions, the nonlinearization of the Lax pairs associated with the discrete hierarchy of a generalization of the Toda lattice equation is proposed, which leads to a new symplectic map and a class of ...

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.

Boundary Lax pairs for the A_n⁽¹⁾ Toda field theories

, 2009
Based on the recent formulation of a general scheme to construct boundary Lax pairs,we develop this systematic construction for the $A_n^{(1)}$ affine Toda field theories (ATFT). We work out explicitly the first two models of the hierarchy, i.e. the sine-

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 ...

Breather and Rogue Wave Solutions of a New Three-Component System of Exactly Solvable NLEEs

Dynamics
We derive a new exactly solvable multi-component system of non-linear evolution equations (NLEEs). The system consists of three 1+1-dimensional evolution equations—one first-order and two second-order in the spatial variable.

The Delsarte-Darboux type binary transformations, their differential-geometric and operator structure with applications. Part 1 [PDF]

Opuscula Mathematica, 2006
The structure properties of multidimensional Delsarte-Darboux transmutation operators in parametric functional spaces are studied by means of differential-geometric and topological tools.

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 ...

Preserved anterolateral ligament graft continuity on MRI and lower knee laxity after ACL graft failure than before index combined ACL–ALL reconstruction: A retrospective case series

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To evaluate magnetic resonance imaging (MRI)‐based continuity and signal characteristics of reconstructed anterolateral ligament (ALL) grafts and compare anteroposterior and rotational knee laxity after anterior cruciate ligament (ACL) graft failure with values recorded before the index combined ACL–ALL reconstruction.

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 ...
