Which type of knee prosthesis is specifically designed for K1-K2 control?

The type of knee prosthesis specifically designed for K1-K2 control is mechanical knees with single speed. These prostheses are aimed at individuals who have limited mobility, as classified by the K levels. K1 indicates a patient who can walk with a reasonable speed, while K2 indicates the ability to traverse low-level environmental barriers—like curbs or stairs.

Mechanical knees with single speed are simple in design and adjustment, providing a fixed resistance during walking. This allows for a consistent gait pattern that suits the functional levels of K1 and K2 patients. The straightforward mechanism requires less sophisticated control than other types of knees, making it easier for individuals with these K levels to manage and use effectively in daily activities.

In contrast, fluid-controlled knees and microprocessor knees offer more advanced features that provide adaptive responses suited for higher K levels, allowing for a more dynamic range of motion and feedback based on activity type and walking speed. Dynamic response knees focus on accommodating activities that require more variability in movement and speed, which are generally beyond the demands of K1-K2 users.
