Existence of parameterized BV-solutions for rate-independent systems with discontinuous loads. [PDF]

, 2021
We study a rate-independent system with non-convex energy in the case of a time-discontinuous loading. We prove existence of the rate-dependent viscous regularization by time-incremental problems, while the existence of the so called parameterized $BV$

Diagnosis of periprosthetic joint infections in patients who have rheumatoid arthritis: application of routine serological and synovial fluid indexes

Bone & Joint Research, 2023
Aims: To investigate the optimal thresholds and diagnostic efficacy of commonly used serological and synovial fluid detection indexes for diagnosing periprosthetic joint infection (PJI) in patients who have rheumatoid arthritis (RA).

Computational analysis of tibial slope adjustment with fixed-bearing medial unicompartmental knee arthroplasty in ACL- and PCL-deficient models

Bone & Joint Research, 2022
Aims: A functional anterior cruciate ligament (ACL) or posterior cruciate ligament (PCL) has been assumed to be required for patients undergoing unicompartmental knee arthroplasty (UKA). However, this assumption has not been thoroughly tested. Therefore,

Wilbrand's Knee: To Be or Not to Be a Knee? [PDF]

Journal of Neuro-Ophthalmology, 2020
Abstract: Wilbrand's knee of the optic chiasm refers to crossing fibers from one optic nerve that stray for a short distance into the opposite optic nerve before joining the optic tract. This loop of aberrant axons, although small, has generated much controversy.

High rate of tibial debonding and failure in a popular knee replacement: a follow-up review

Bone & Joint Open, 2022
Aims: Total knee arthroplasty (TKA) is a common and safe orthopaedic procedure. Zimmer Biomet's NexGen is the second most popular brand of implant used in the UK. The primary cause of revision after the first year is aseptic loosening.

A quasilinear differential inclusion for viscous and rate-independent damage systems in non-smooth domains [PDF]

, 2013
This paper focuses on (incomplete) rate-independent damage in elastic bodies. Since the driving energy is nonconvex, solutions may have jumps as a function of time, and in this situation it is known that the classical concept of energetic solutions for ...

Older age at surgery and postoperative leg length discrepancy are risk factors for unfavourable patient-reported outcome measures of knee tumour endoprostheses following resection for musculoskeletal tumour of the lower limb

Bone & Joint Open, 2023
Aims: To evaluate mid-to long-term patient-reported outcome measures (PROMs) of endoprosthetic reconstruction after resection of malignant tumours arising around the knee, and to investigate the risk factors for unfavourable PROMs.

Balanced viscosity solutions to a rate-independent system for damage

, 2019
This article is the third one in a series of papers by the authors on vanishing-viscosity solutions to rate-independent damage systems. While in the first two papers (Knees, D. et al. 2013 Math. Models Methods Appl. Sci.23(4), 565–616; Knees, D.

Satisfactory medium- to long-term outcomes of cemented rotating hinge prosthesis in revision total knee arthroplasty: a specialist centre study with minimum four years’ follow-up

Bone & Joint Open, 2023
Aims: The aim of this study was to evaluate medium- to long-term outcomes and complications of the Stanmore Modular Individualised Lower Extremity System (SMILES) rotating hinge implant in revision total knee arthroplasty (rTKA) at a tertiary unit. It is
