This experimental study was undertaken to identify the surface and internal stress distribution and load transmission in menisci under different loading states using a three‐dimensional photoelastic method. These studies were carried out in four series of loading tests on models of menisci. Our observations showed that the stresses of the medial and lateral menisci were concentrated at the central strip of the menisci and that the magnitude of stresses on the superior surfaces of the menisci were greater than that on the inferior surfaces. The load bearing capacity of the lateral menisces where greater than that of the medial one. The results also showed that a complex apparatus, composed of the menisci and other associated structures surrounding the knee joint, plays an important role in the course of force transmission. In addition, the cause of meniscal splitting and the experimental method are discussed. © 1994 Wiley‐Liss, Inc.
