Targeting ligament boundaries rather than alignment boundaries in augmented‐reality‐assisted total knee arthroplasty ensures comparable gait patterns between operated and contralateral limbs

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Modern personalised total knee arthroplasty (TKA) techniques aim to mimic natural knee kinematics by focusing on soft‐tissue dynamics rather than static alignment. However, a consistent definition of the optimal ligamentous balance has not yet been established.

Construction of a Lax Pair for the E_6^{(1)} q-Painlevé System

Symmetry, Integrability and Geometry: Methods and Applications, 2012
We construct a Lax pair for the $ E^{(1)}_6 $ $q$-Painlevé system from first principles by employing the general theory ofsemi-classical orthogonal polynomial systems characterised by divided-difference operators on discrete, quadratic lattices [arXiv ...

Managing the meniscus Part 2: Traumatic tear patterns, biologic augmentation, transplantation, innovation and future research

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Acute, traumatic meniscus tears are common and should be repaired whenever possible. However, the biological age of the patient, along with the specific tear morphology, may significantly influence the selection of the repair technique, expected clinical outcomes and the postoperative rehabilitation protocol.

Cross-linguistic Phonological Transfer:

Crossings
The perception and acquisition of non-native tense and lax vowel contrasts have been the subject of extensive research (Bustos et al., 2023; Chang, 2023; Fabra & Romero, 2012; Lai, 2010). Previous studies have highlighted various factors influencing the

No difference in patella mobility between conventional mechanically aligned and robotic‐assisted functionally aligned total knee arthroplasty

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Robotic‐assisted (RA) surgery allows for higher accuracy in total knee arthroplasty (TKA) and for better standardization of alignment concepts. It was hypothesized that the more personalized component placement in functional robotic‐assisted total knee arthroplasty (RA‐TKA) would show an impact on patella mobility and clinical outcome.

Lax pairs for BKM hierarchy

We construct Lax pairs for the recently (2023) introduced integrable PDE systems known as the BKM equations. As many known and previously studied integrable systems are special cases of the BKM systems, our construction provides Lax pairs for many integrable hierarchies, including previously studied ones such as Camassa-Holm, Dullin-Gottwald-Holm, cKdV,

Hamiltonian Monodromy via spectral Lax pairs

Journal of Mathematical Physics
Hamiltonian Monodromy is the simplest topological obstruction to the existence of global action-angle coordinates in a completely integrable system. We show that this property can be studied in a neighborhood of a focus-focus singularity by a spectral Lax pair approach.

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.

On commuting differential operators

Electronic Journal of Differential Equations, 2000
The theory of commuting linear differential expressions has received a lot of attention since Lax presented his description of the KdV hierarchy by Lax pairs $(P,L)$. Gesztesy and the present author have established a relationship of this circle of ideas

Tibia‐first, gap‐balanced patient‐specific alignment in total knee arthroplasty achieves better ligament balance than mechanical, kinematic and functional alignment strategies

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose This study evaluates four different alignment techniques to assess total knee arthroplasty (TKA) balance. Methods A prospective cohort of 400 patients undergoing primary robotic‐assisted cruciate‐retaining TKA was analysed. The Velys TKA robotic system collects a balance curve that enables the surgeon to intraoperatively analyse the ...
