This is a corollary from the theory of lubrication. The term and its underlying theory are explained. Synovial fluid forms a convergent lubricant film between joint surfaces, fatty pads reduce curvature in highly curved joints, intra‑articular discs and menisci increase curvature in low‑curvature joints, and sesamoid bones exert bow‑string pressure on articulating bones. The abstract contains four numbered items.
1. Synovial fluid acts mechanically by forming a convergent lubricant film between the fixed and the moving joint surfaces. This term and the underlying theory are explained. 2. The fatty pads assist lubrication by reducing the "mechanical curvature" in joints with more highly curved surfaces. 3. The intra-articular discs and menisci increase the "mechanical curvature" in joints with surfaces of small curvature. 4. Sesamoid bones exert a "bow-string pressure" upon the bones with which they articulate. This is a corollary from the theory of lubrication.
