Introduction: People with an upper leg amputation (PULA) have a higher energy cost than able bodied subjects during walking, however the causes are still poorly understood. Knowing that the abnormal gait of PULAs is a reflection of a repertoire of compensation mechanisms, it can be suggested that there is a relation between the energy cost of walking and the use of compensation mechanisms. The role of the different prosthetic knees in this relation is also important but has not been investigated yet. Therefore the aim of this study was to investigate the relation between compensation mechanism, energy cost and the prosthetic knees in the gait of PULAs. Method: One unilateral transfemoral amputee participated in this study. The participant walked with five different prosthetic knees (3R20, 3R60, 3R106, Mauch SNS and C-leg) while joint kinematic, kinetics and energy cost were measured. Results: Compensation mechanisms were observed when walking with the 3R20, the 3R106, the Mauch SNS and the C-leg. The 3R20 caused hip hiking, walking with the 3R106 showed an abducted gait pattern and used pelvic rotation. When walking with the Mauch and C-leg a combination of an abducted gait and hip hiking was demonstrated. Walking with the 3R20 and the C-leg resulted in the highest energy cost while walking with the Mauch SNS demonstrated the lowest energy cost. Conclusion: No clear relation could be demonstrated between the sophistication of the knees and the compensation mechanisms. Besides, a relation between the compensation mechanisms and energy cost was only shown in the C-leg. However, a relation between energy cost and the prosthetic knee was demonstrated when the C-leg was excluded. Key words: amputee, gait, energy cost, range of motion, vaulting, hip hiking, pelvis rotation, prosthetic knee.
