Abstract

New components of synovial tissue which provide unusually lower friction in joints were detected. Data on previously unknown ability of capsular-ligamentous tissues to be a conductor of oiling substances into joint cavity were obtained. Composition and significance of osseous fat were determined. Osseous fat was both a oiling substance consists of triglycerides, cholesterine ether and depot of fat-soluble antioxidants. High content of antioxidants was revealed in capsula and bones adjacent to articular cartilage
