India has a large young population with limb loss, especially from low economic strata, trauma being the major cause, suddenly takes a toll on the finances of the amputees. A low-cost endo-skeletal prosthetic knee joint, named ‘Safe Gait’ has been designed and developed, with a mechanism of free knee joint with swing assist and a lock that can be operated at will and with ease by a patient at any point of time and terrain. Objective: The present study aims to assess the TFA using SGPKJ on the functional outcomes and compare to the patients wearing other imported prosthetic knee joint (OIPKJ) like polycentric knee joint, hydraulic knee joint, etc. It was hypothesized that SGPKJ would provide stability and mobility at a very low cost and thus could be an option for non-affording TFA. Methods: This was an ‘Open-label’ study. The participants who satisfied the inclusion criteria were divided into two groups based on their prosthetic options, they were compared on functional measures like single limb stance time in a sec, Time Up and Go Test, & Six Minutes’ Walk Test. Results: Show single-limb stance as 1.39 sec & 1.48 sec; Gait speed as 1.37 m/sec & 141m/sec in Safe Gait Prosthetic Knee Joint and Other Imported Prosthetic Knee Joint resp. There was no statistically significant difference between the two groups in other parameters viz. TUG & 6MWT. Conclusion: The participants with SGPKJ were found to be compatible with mobility and stability on various locomotor tests.
