The 21-year-old midfielder has suffered three ACL injuries on the same knee and has not played AFL football since his debut 2010 season.
The highly talented Morabito has already had two regular ACL reconstructions but after again tearing the graft on the repaired ligament, he has decided to have the LARS procedure.
Morabito, 21, went down with the cruel injury during a training drill at Fremantle Oval, twisting awkwardly as he attempted to tackle young teammate Tanner Smith.
Morabito's father, Vince told PerthNow that Anthony "was pretty close (to retirement), but he made the decision to play on, we didn’t push him into it."
If the surgery is successful Morabito could expect to return midway through the 2013 season.
The number four national draft pick in 2009 who had played 23 games in a stunning 2010 season will have the surgery in Sydney next week.
Fremantle football manager 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 and the football club, 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.”
Sydney Grand Final hero Nick Malceski was the first AFL player to have the radical LARS surgery back in 2008 and again in 2011 and is said to be a big supporter of it.
Other AFL players who have had the LARS surgery include David Rodan (Port Power), Josh Drummond (Brisbane), Brad Fisher (Carlton), Brett Ebert (Port Power), Campbell Heath (Sydney) and Brett Staker (Brisbane).
