What is one of the advantages of using a Liner + Pin system for TF prosthetics?

The use of a Liner + Pin system for transfemoral (TF) prosthetics provides a distinct advantage in that it facilitates seated donning with a positive lock. This feature is particularly beneficial for users because it allows them to easily put on the prosthetic while sitting down, which can be a more comfortable and accessible position for many individuals. The positive lock mechanism ensures that the prosthetic component is securely attached once donned, reducing the risk of it becoming dislodged during use.

While mobility is important, this system does not inherently provide greater mobility without restrictions. The Liner + Pin system enhances the ease of donning, but users may still experience some limitations based on their physical condition and the design of the prosthetic itself. Additionally, while this system can reduce skin irritation through the protective lining, it does not completely eliminate the risk of skin issues, as skin health also depends on factors like hygiene and fit. Furthermore, precise fitting is still important in a Liner + Pin system to ensure comfort and functionality, as a poor fit could lead to problems such as rubbing or instability.
