在测量膝关节弹性的过程中，连续记录模拟积液中的压力。当关节为空，或在相对较低的压力下仅包含小体积时，获得直线迹线，表明关节内压力是恒定的。然而，在某些受试者中，随着模拟渗出液体积的增加，出现了细微的脉动。随着进一步的液体加入，脉动起初增加，然后减少，最后消失。搏动总是与动脉搏动同步。研究对象
In the course of measurement of knee joint elastance, pressures in simulated effusions were continuously recorded. With the joint empty, or containing only small volumes at relatively low pressures, straightline tracings were obtained, indicating that the intra-articular pressure was constant. However, in some subjects, at increasing volumes of simulated effusion, a fine pulsation appeared. As further fluid was added, the pulsation increased at first, then diminished, and was finally obliterated. The pulsations were always synchronous with the arterial pulse. Subjects studied
