Official title

Microprocessor Knee Versus Mechanical Knee: Impact on Functional Outcomes in Dysvascular Transfemoral Amputees

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

In older adults, poor circulation in the lower extremities leads to serious health complications including limb loss. In addition, individuals with dysvascular disease also suffer from other co-morbidities like diabetes, coronary and cerebrovascular disease. An individual with a transfemoral (TF) amputation is usually fitted with a prosthetic limb to assist with function, including a prosthetic knee and a prosthetic foot. Currently, dysvascular amputees are given a prosthetic knee based on the basic expectation that they will be functionally stable. This consideration does not address higher levels of function like walking at multiple speeds and over uneven ground. Also, dysvascular amputees are not able to counteract their co-morbidities with a more active lifestyle. Walking is less energy efficient; their traditional prostheses may cause early onset of fatigue and induce a fear of falling. Newer microprocessor knees enable patients with transfemoral amputations to walk on different surfaces and at multiple cadences through better control in swing and stance phases of gait. The impact of the functional differences in the prostheses is not clear and requires additional investigation to clarify the choice of the most appropriate functional prosthesis. The purpose of this study is to compare the functional outcomes with the traditional mechanical knee versus the microprocessor knee (C-leg) in transfemoral amputees.
