牛关节在最大可能的静态载荷下在一个装置中振荡，该装置在关节运行时测量它们的摩擦系数。通过大体和组织学检查评价关节磨损。关节在载荷下振荡，刚好低于关节的结构能力，即使经过很长一段时间也没有显示出明显的磨损。当周期性的冲击负荷加入到这个方案中，软骨磨损变得迅速，很容易辨别。这些发现的影响，关节软骨的磨损进行了讨论。
Bovine joints were oscillated under the maximum possible static load in a device which measured their coefficients of fraction while the joints were running. Joint wear was evaluated by gross and histologic inspection. Joints oscillating under loads, just below the structural capability of the joints, did not show significant wear even after long periods of time. When periodic impact loading was added to this regimen, cartilage wear became rapid and was easily discernible. The implications of these findings to the wearing away of articular cartilage are discussed.
