Martyn scored two centuries in the 3-0 series sweep over Sri Lanka but feared his return to Test form could have triggered a knee problem exacerbated by the hard Sri Lankan grounds and a compressed playing schedule.
But the right-hander can now look ahead to the May-June tour of Zimbabwe after scans on Tuesday cleared him of serious damage. The scans revealed Martyn, 32, had inflammation in the kneecap and behind the joint, which could be treated by physiotherapy.
Having missed a lot of cricket because of the broken finger he suffered during the 2003 World Cup, Martyn was desperate to avoid another lay-off after eclipsing his miserable Australian summer with 333 Test runs in Sri Lanka at 55.50.
"I've been playing for a long time now and I think it's just built up over time and they feel at the moment there's no use rushing in and getting anything done," Martyn said in Melbourne on Tuesday.
"Hopefully, it will be right for the lead-in for the summer coming up and (I'll have) just a bit of rehab and physio and make sure it's OK."
Martyn, Matthew Hayden (knee) and Michael Kasprowicz (shoulder) were the major Australian casualties during the Sri Lankan tour after throwing themselves around in the field on flint-hard surfaces.
Martyn said the tour was one of his most satisfying, especially in the lead-up to the series in India later this year and particularly to have batted so well against prodigious spinner Muttiah Muralitharan.
He said Murali was one of the most difficult bowlers to face, and that his 'doosra' was a tough delivery to negotiate.
Martyn declined to discuss the new chucking claims against Murali. "It's the standard line for us, we can't comment on it," he said. "It's not up to us and now it's up to the International Cricket Council (ICC) to look into the matter."
