Role of hyaluronic acid in joint lubrication.

Hyaluronic acid is the macromolecule which endows synovial fluid with its viscoelastic properties and it is often assumed these properties are important for the lubrication of the tissue surfaces in diarthrodial joints (Barnett, Davies, and MacConaill, 1961). The relationships, if any, that exist between the chemical and physical properties ofsynovial fluid and its lubricating ability, however,...

"Boosted lubrication" in synovial joints by fluid entrapment and enrichment.

The manner in which a human load-bearing synovial joint is able to carry the applied loads has been the subject of speculation for many years. In the past, a number of theories have been advanced each using as a basis one of several modes of lubrication well known to mechanical engineets. More recently some of the more unique characteristics of human cartilage have been recognized, and theories...

Squeeze-film Lubrication of the Human Ankle Joint: a Simplified Analytical Model during Walking

The aim of this paper is to propose an analytical approximate squeeze-film lubrication model of the human ankle joint for a quick assessment of the synovial pressure field and the load carrying due to the squeeze motion, considering both normal and pathological behaviour. The model starts from the theory of boosted lubrication for the human articular joints lubrication (Walker, et al., 1968; Ma...

Mechanism of Boundary Lubrication and Wear of Frictionless Synovial Joint

The natural synovial joints have excellent lubricating ability to provide very low frictional resistance and high wear resistance during various activities of human being. Synovial fluid is having mainly constituents of glycoproteins and phospholipids. Albumin adsorbs over globulin by hydrophobic bonding after formation of globulin coating on hydrophilic cartilage surface and phosphatidylcholin...
