Hi,

The machine you are talkin about seems to be IFT (interferential therapy), used for pain modulation.

Before we move ahead about how long it wud take for it to heal, i would like to know what is the problem that ur facing right now and how old is ur injury and what improvement do u feel in ur knee since injury. does it get locked? is it painful?, or is it swollen? what is ur main problem right now .
