What problem might you suspect if a transtibial user experiences distal patella pain?

• A. The socket is too short
• B. The prosthetic foot is too light
• C. Bottoming out
• D. Socket position is too far back

Answer: (C)

Experiencing distal patella pain in a transtibial prosthesis user is often indicative of the socket design or alignment not adequately supporting the residual limb. When we refer to "bottoming out," we are specifically talking about a situation where the residual limb makes excessive contact with the bottom of the socket during weight-bearing activities. This excessive contact can lead to increased pressure and pain around the distal patella region. When the user fully bears weight, if the limb reaches the end of the socket too quickly, the tissue around the patella may be compressed, leading to discomfort and pain. This scenario highlights the importance of proper socket fit and alignment; ensuring that the socket allows for full activity without causing undue pressure is essential for comfort and functionality. Understanding this concept helps in recognizing that the fit and design of the prosthesis, particularly in relation to weight distribution and alignment, plays a crucial role in the overall comfort and effectiveness of the device.
