Identification and evaluation of the role of the arthro-medullary connection in the functioning of human joints (experimental study)

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
