Joint Lubrication with Artificial Lubricants [PDF]
Arthritis & Rheumatism, 1971 AbstractThe joint lubricating properties, in vitro, in bovine metatarsal‐phalangeal joints, of silicone fluid, methyl cellulose and polyvinyl‐pyrrolidone were compared to buffer, serum and synovial fluid. As had been previously reported, synovial fluid was almost twice as good as serum and buffer, which are equivalent in their joint lubricating ...
