Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to determine if transfemoral amputees of varied etiology will demonstrate increased function, safety and quality of life following accommodation with a new knee prosthesis as compared to their former C-Leg knee prosthesis.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Prosthetic knee 1 (Otto Bock C-Leg)

This arm included unilateral transfemoral amputees who were assessed while using their preferred knee at study start(C-Leg). The Otto Bock C-Leg is a microprocessor knee using 2 sensors (1 for kinetics and 1 for kinematics).

Group Type ACTIVE_COMPARATOR

Otto Bock C-Leg

Intervention Type DEVICE

Amputees' preferred prosthetic knee.

Prosthetic knee 2 (Otto Bock Genium)

This arm included unilateral transfemoral amputees who were assessed while using the experimental/study knee, the Genium. The Otto Bock Genium is a microprocessor knee using multiple sensors that hypothetically increase mobility functions (e.g. walking backwards, intuitive stance)

Group Type ACTIVE_COMPARATOR

Otto Bock Genium

Intervention Type DEVICE

Study knee.

Non-amputee controls

This was an observational arm including non-amputees who were assessed as non-impaired control subjects. There are no interventions in this observational arm of the study.

Group Type NO_INTERVENTION

No interventions assigned to this group

Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Unilateral transfemoral or knee-disarticulation amputee
* 18 to 85 years of age
* K3 (variable cadence and community) ambulators;
* Current use of and experience with the C-Leg for at least 1 year
* Ability to descend stairs and hills without caregiver and assistive devices
* Be able to independently provide informed consent
* Be willing to comply with study procedures.

Exclusion Criteria

* History of chronic skin breakdown on the residual limb
* Conditions that would prevent participation and pose increased risk (e.g. unstable cardiovascular conditions that preclude physical activity such as walking)
* Use of any assistive devices/walking aids, beyond a prosthesis, to ambulate
* Unwillingness/inability to follow instructions
