Background: Prostheses are used after amputation for better function, cosmetic appearance, and a psycho-spiritual sense of wellbeing. But they are mired by discomforts and disadvantages. Compared to the conventional exoskeletal prostheses, the modern endoskeletal ones claim to be functionally superior. The primary objective of the study was to compare the factors associated with the daily use of endoskeletal and exoskeletal prosthesis among lower extremity amputees who have used the prostheses for a minimum period of 3 months. Secondary objective was to compare the mobility status of persons using endoskeletal and exoskeletal prostheses and to find the difference in social and emotional aspects of persons using endoskeletal and exoskeletal prostheses.

Methods: This was a Cross sectional study, conducted from January 2014 to December 2014, at Government Medical College Hospital, Trivandrum. All the lower limb unilateral amputees who have used the prosthesis for a minimum period of 3 months who attended the Out Patient department of Physical Medicine and Rehabilitation Department were included in the study.

Results: The endoskeletal prostheses were more silent during ambulation, with a statistically significant difference. With regard to utility, it was found that exoskeletal prosthesis had better performance. Regarding ambulation, appearance, frustration, perceived response, residual limb health, social burden and well being no statistically significant difference was noted between the two types of prosthesis. Conclusions: Endoskeletal prosthesis and exoskeletal prosthesis both are having an almost equal acceptability among lower limb amputees. Exoskeletal prosthesis has better performance altogether while endoskeletal prosthesis is better in the silent ambulation aspect.
