Non‐anatomical MPFL reconstruction and failure to address relevant pathologies are common reasons for treatment injuries following treatment for patellofemoral instability

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Management of patellofemoral instability (PFI) tailored to the individual patoanatomy can be complex with potential pitfalls. However, reports on complications and suboptimal outcomes remain limited. The aim of this study was to analyse problems related to PFI treatment in Denmark.

Revision ACL reconstruction using a modified iliotibial band–allograft technique for combined ACL and lateral extra‐articular procedure achieves comparable outcomes to bone–patellar tendon–bone with modified Lemaire

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose In revision anterior cruciate ligament reconstruction (R‐ACLR), adding a lateral extra‐articular procedure (LEAP) reduces graft failure and postoperative laxity. Iliotibial band (ITB)‐based techniques may avoid patellar tendon harvesting morbidity, but evidence in adults, particularly in revision cases, remains limited.

Four‐Dimensional pp‐Wave Lie Groups and Harmonic Curvature

Mathematische Nachrichten, EarlyView.
ABSTRACT We determine all four‐dimensional Lie groups which have harmonic curvature. In parallel, a description of four‐dimensional pp‐wave Lie groups is obtained.

Kuga–Satake Construction on Families of K3 Surfaces of Picard Rank 14

Mathematische Nachrichten, EarlyView.
ABSTRACT The isometry between the type IV6 and the type II4 hermitian symmetric domains suggests a possible relation between suitable moduli spaces of K3 surfaces of Picard rank 14 and of polarized abelian 8‐folds with totally definite quaternion multiplication. We show how this isometry induces a geometrically meaningful map between such moduli spaces

Shape Derivatives of the Eigenvalues of the de Rham Complex for Lipschitz Deformations and Variable Coefficients: Part II

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this second part of our series of papers, we develop an abstract framework suitable for de Rham complexes that depend on a parameter belonging to an arbitrary Banach space. Our primary focus is on spectral perturbation problems and the differentiability of eigenvalues with respect to perturbations of the involved parameters. As a byproduct,

Linear Toroidal‐Inertial Waves on A Differentially Rotating Sphere with Application to Helioseismology: Modeling, Forward and Inverse Problems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT This paper develops a mathematical framework for interpreting observations of solar inertial waves in an idealized setting. Under the assumption of purely toroidal linear waves on the sphere, the stream function of the flow satisfies a fourth‐order scalar equation.
