The 21-year-old midfielder has not appeared in an AFL game since his debut 2010 season following three ACL injuries on the same knee.
Morabito has already undergone two reconstructions in his short career and after tearing the graft on the repaired ligament during training last week, he has decided to have the LARS procedure.
General manager football operations Chris Bond said it was important Morabito was given time to reach his decision.
“Anthony really just needed some time and space to weigh up his surgery options,” Bond said.
“After discussions with people close to him, the football club and medical experts, Anthony has decided that this surgery will give him the best chance to resume his playing career.”
Bond said the club wasn’t putting any time frame on a return date for Morabito.
“Obviously with LARS there’s a shorter time frame with coming back, but we think he just needs to get back from the surgery and make sure that everything is okay first,” Bond said.
“We’ll see how he recovers from that and then we’ll have a better idea.”
