Investigation of Tire‑Tread Rubber Hysteretic Behaviour on Aggregates Through Experiments and Modelling

Journal of Tribology, EarlyView.
ABSTRACT Friction between tire rubber and pavement is governed by the interplay of hysteresis and adhesion yet their individual contributions remain difficult to quantify. This study addresses the long‐standing challenge by using reciprocating sliding tests by means of a tribometer and viscoelastic finite element modelling (FEM) to investigate rubber ...

Gait alterations increase friction of degenerated articular cartilage: A tribological study

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To investigate the effect of gait alterations associated with osteoarthritis (OA) on the frictional properties of porcine articular cartilage (AC) in intact and degenerative conditions. Methods Forty‐eight cylindrical AC samples were harvested from 12 porcine femur condyles and equally divided between four groups with n = 12 samples ...

Review of the Tribological Characteristics of Synovial Fluid

Procedia Technology, 2016
AbstractMovement of the knee joint requires an effective lubrication mechanism. Synovial fluid is reported to serve this function. Synovial fluid is an extra cellular biofluid present in the synovial joint of living beings. Numerous studies have been conducted on the characteristics of synovial fluid.

Kinematic alignment reduces tibial internal rotation and maintains a larger retropatellar contact area than mechanical alignment in early flexion in valgus knees

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose Alignment effects after total knee arthroplasty (TKA) may be particularly relevant in valgus phenotypes. This study compared kinematic alignment (KA) and mechanical alignment (MA) in valgus cadaveric knees during active, muscle‐loaded flexion, using the native knee as reference.
