A correct prosthetic fitting in the sagittal plane primarily aims to achieve stability throughout stance. This is crucial because stability allows the individual to maintain balance and support their weight effectively while standing and during the gait cycle. In the sagittal plane, proper alignment and fitting ensure that the forces acting on the prosthesis are managed effectively, reducing the risk of falls and improving functional mobility.

In terms of functionality, stability is vital when engaging in activities that require standing, walking, or running. A well-fitted prosthetic device enhances confidence and independence for the user by minimizing the adjustments they must make to cope with instability.

While reduction of overall weight, comfort during swing, and observation of physical appearance are important factors in prosthetic design and user satisfaction, they do not directly address the critical need for stability in the sagittal plane during stance. Focusing on stability helps facilitate better movement patterns and promotes a natural gait, which is ultimately the most important objective of a prosthetic fitting.
