Comparative Outcomes Assessment of the C-Leg With a New Knee Prosthesis

Comparative Outcomes Assessment of the C-Leg With a New Knee Prosthesis

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.

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
