A distinction must be drawn between the older constrained prostheses, in which load was transferred via metal-coated hinges, and later models using the low-friction principle, where the axle is not load bearing. The latter show good long-term results. The greater stability of constrained prosthesis allows earlier and less complicated mobilization even of elderly patients.
必须区分老式的受限假体和后来采用低摩擦原理的型号。老式受限假体通过金属涂层铰链传递负荷，而后来的型号中轴不承重。后者显示出良好的长期效果。受限假体具有更高的稳定性，即使对于老年患者也能实现更早且更简单的活动。
