Study Arms:
- Prosthetic knee joints (Type: EXPERIMENTAL): Each subject will be tested using their current Non-Microprocessor Knee (NMPK) , fit and tested with a Microprocessor Knee (MPK), and then tested again with their NMPK, e.g. A-B-A design.

Based on this trial design, predict the completion outcome and termination type (if applicable).
