The 22-year-old Italian, whose first year at Anfield has been marred by injuries, was ruled out for the rest of the season after dislocating the joint and undergoing surgery in February.
Borini, a £10.5million signing from Roma last summer, missed three months earlier in the campaign with a broken foot.
Borini wrote on Twitter: "Who i should be and who I feel to be" today first full training after injury!!! #be #firstraining #back #happy."
Borini has scored just one goal in 16 appearances since joining the Reds.
