Prosthetics

A transtibial socket that covers the knee is called a:

• Total contact socket

• Patellar tendon-bearing socket

• Supracondylar socket

• SACH socket

A pin/lock suspension system involves:

• Using suction for suspension

• Securing the residual limb with a pin

• Strapping the socket to the residual limb

• Securing the socket using laces

How does a polycentric knee unit differ from a single-axis knee unit?

• It allows only one type of movement

• It has a lower weight limit

• It provides greater stability

• It has multiple pivot points

A single-axis knee prosthesis is typically defined by:

• Simple mechanical design

• Enhanced stability

• Limited adaptability

• Low weight
