Treatment: Devices - Power Knee with bone anchored suspension
Treatment: Devices - C-Leg
Treatment: Devices - Rheo Knee XC

Cohort 1 (arms 1-3) - * Arm 1 will be designed as observational study providing the efficacy and safety of the load applied on osseointegrated fixation by transfemoral BAP fitted with the Power Knee for the whole cohort of 20 participants.
* Arm 2 will be designed as matched case-control study comparing the efficacy and safety the load applied on osseointegrated fixation by transfemoral BAP fitted with Power Knee and usual MPKs (e.g., C-Leg, Genium) for the whole cohort of 20 participants.
* Arm 3 will be designed as matched case-control study comparing the efficacy and safety the load applied on osseointegrated fixation by transfemoral BAP fitted with Power Knee and Rheo Knee XC for a subgroup of 5 participants.

Cohort 2 (arm 4) - • Arm 4 will be designed as matched case-control study comparing the efficacy and safety the load applied on osseointegrated fixation by transfemoral BAP fitted with Power Knee for the whole cohort of 20 participants and non-MPKs for another cohort of 10 participants.
