This study focused on the properties of biofluid, a new formulation proposed to generate synthetic synovial fluid using Castor Oil, and three various compositions of Hyaluronic acid (HA) which are 0 ml, 5 ml, and 10 ml as the addition for total knee replacement (TKR) utilising the Pin-on-Disc approach. This research led to the use of vegetable oils as bio-fluid lubrication, which may imitate the characteristics of synovial fluid with friction coefficients as low as 0.03 while being safe for the human body. Thus, the frictional force, friction coefficient, and wear rates indicated by the sample at the same pace of activity, 6 kg, and speed of 60 rpm, were investigated in this study. The study used 316L stain- less steel as the pin and Polylactis Acid (PLA) as the disc to duplicate the notion of stress and compression on artificial joints. The friction coefficient in this investigation is 0.023, and the average frictional force is 1.574N. The average wear is 0.005303 mm. This experimental study's key contribution is that it demonstrates how castor oil may be treated with HA to function as a lubricant for artificial joints and how modern medicine can use it to treat synovial fluid-related issues. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.
