The porous surface of the MCCL prosthesis macroscopically resembles spongy bone, with a porous depth of up to 10 mm, the width of the pores measuring 1-2 mm, with reticular spaces forming an intercommunicating system. The superficial porous surface and the implant stem are combined in a single structure. The standard prosthesis is made up of four components; an acetabulum in cobalt-chrome-molybdenum alloy, an interposed layer of polyethylene, a ceramic head and a stem in cobalt-chrome-molybdenum alloy, the shape of which is anatomically matched to the proximal femur. What emerges from the present study is the possibility of using right and left stems, each available in six sizes. The ceramic head may be attached to the neck of the femoral stem, which may be long, average, or short. An "extra-long" metal head is also available.
MCCL假体的多孔表面在宏观上类似于松质骨，多孔深度可达10毫米，孔隙宽度为1-2毫米，网状间隙形成一个相互连通的系统。表面多孔表面和植入柄结合为一个单一结构。标准假体由四个部件组成；一个钴铬钼合金髋臼、一层聚乙烯中间层、一个陶瓷头和一个钴铬钼合金柄，其形状在解剖学上与股骨近端相匹配。本研究表明，可以使用左右两种柄，每种柄有六种尺寸可供选择。陶瓷头可以连接到股骨干的颈部，股骨干可以是长的、中等的或短的。还有一种“超长”金属头可供选择。
