Robertson, 29, ruptured his right achilles during the third quarter of Sunday's loss to St Kilda, and will consequently miss the rest of the season after undergoing surgery on Monday to reattach the severed tendon.
The doctor said as long as the club is patient with his recovery and aim to gradually get strength and stretch back into his calf, there is little chance the spearhead will suffer the same fate as former Hawk Simon Beaumont, who was forced into retirement following the same complaint.
"If he's given the right rehabilitation, he should be able to get back to things," the doctor told afl.com.au.
"He should be able to have a good recovery. The older players do find it harder to take a longer period of time out from the game, but he won't play this year so he's got all of the season and then pre-season to do his rehabilitation and get his fitness back."
Beaumont tore his achilles in round 14, 2005, while playing against Geelong. He retired at the end of that year, aged 29.
However, Collingwood's Anthony Rocca, Port Adelaide's Michael Wilson and former Richmond captain Wayne Campbell have all made successful comebacks from the injury in the past five years.
Rocca was two years younger than Robertson is now at the time of his injury, but both Wilson and Campbell were 30 when they began their rehabilitation from the painful complaint in 2007 and 2003 respectively.
A full rupture of the achilles tendon is not common in Australian Rules football, but as the statistics indicate, it's more likely to happen to a mature-aged player than an emerging one.
There is also the chance the tendon can recoil through the leg and complicate recovery if left untreated, which is why the Demons were keen to have Robertson operated on within 24 hours of suffering the tear.
"It's important that if you're going to have the surgery that you do it within the first five days," the doctor said.
"Having it done within the first few days is important, but the common practice is that they try and do it within the first day.
"People can't walk with it so they are operated on. Some older people choose to have a prolonged period of plaster instead of surgery, but for an active athlete, he needs to have it repaired."
Robertson can expect to have "three to four months off" in order to give himself the best chance of a full recovery, as he attempts to overcome the injury that was sustained in fairly innocuous circumstances.
The Melbourne forward was in the centre square and suffered the injury when he routinely sprung up into a contested marking situation during the Telstra Dome match on Sunday afternoon.
"The incident is usually just a running, pushing off incident," the doctor confirmed.
"The achilles works every time you take each stride as you push off with your toes, so it's common that it's an incident that doesn't involve huge forces; it's usually just a running episode, often as the person takes the first couple of steps in a sprint or pushes off the ground."
Melbourne released a statement on Monday evening claiming the surgery to repair the achilles had gone well.
"The surgery was successful, with the tendon being stitched back together," club doctor Andrew Daff said.
"We expect that Russell will return to training in five to six months."
