“…Most likely, the secondary structures of SF proteins and tropocollagen are affected in OA . Most of the studies found are concerned with adsorption and desorption of proteins in different kinematic conditions and film thickness in different pH, buffer, and concentration of proteins . Frictional coefficients, frictional force, shear force, wear measurement, boundary lubrication, surface geometry, rheology of various constituents are also considered in connection with proteins and other SF components to explore the knowledge in this area .…”

“…The thickness of the lubricating film can be assumed to scale specifically with the deposited amount of albumin. Presumably, a thin layer of γ‐globulin is adsorbed primarily on to rubbing surfaces, enabling subsequent adsorption of albumin to create a layer structure . Thus, this model fluid can be used for chemical composition analysis.…”

“…In particular, hyaluronic acid, proteins, and phospholipid concentrations varied widely in patients undergoing the joint replacement . The thickness of lubricant film within hip prostheses is hypothesised to influence particular proteins . It has also been stated that concentrations of bovine serum albumin (BSA) and γ‐globulin manipulate the frictional behaviour of the CoCr femoral head .…”

This study provides a systematic review of the synovial and simulated body fluid research for the last 10 years (2006 to 2016). In particular, biochemical and mechanical properties of synovial fluid after joint replacement are focused, namely, the chemical composition of the formed lubricating film and structural changes of the associated proteins under mechanical loading. In summary, the formation of the film depends on pH, viscosity, and concentration of the solution, static, sliding, and rolling conditions and other factors related to the joint replacement. However, chemical changes of the synovial fluid proteins after the joint replacement are rarely addressed and require further attention. To this end, we provide a preliminary study of selected proteins within the synovial fluid using Raman spectroscopy. We conclude that chemical analysis together with the analysis of mechanical and biological properties of the synovial fluid after total joint replacement will help in comprehension of the process.

“…For detailed clarification of presented data could be helpful in situ observation of contact through optical methods. Their benefit was already presented in the field of biotribology of hip joint replacements (Nečas, 2015 andNečas, 2018).…”

“…After this, they start to increase more rapidly. This can be explained by mechanism published by Nečas (2015). During adsorption of proteins on solid surfaces, γ-globulin forms thin protein layer; therefore, friction is very similar to γ-globulin solution at the beginning of the test.…”

The presented study deals with the analysis of the tribological behaviour of the Ti6Al4V alloy manufactured conventionally. The study aimed to verify whether the titanium alloy is suitable for use as a contact material in small joint implants, as additive manufacturing of this alloy can in the future provide certain benefits, such as individualization and simplification of the implant construction, or controlled porosity. The tested pair consisted of a pin and a glass plate lubricated with model synovial fluid. The contact area was observed with colorimetric interferometry. Alongside film thickness, friction, and wear scars were measured. From the designed experimental conditions, the titanium alloy was not able to create a sufficiently thick lubrication film to overcome its surface roughness and damage to contact surfaces occurred. Friction was comparable for all the tested configurations. The application of conventionally manufactured titanium alloy as a contact surface in small joint implants seems to not be suitable since its performance fell short when compared to conventional cobaltous alloy. Nevertheless, there are various alternative methods available, such as unconventional manufacturing, polishing, surface texturing, and coating. Graphical Abstract
