The Shanghai Shenhua forward sustained the injury in action for Shenhua in the Asian Champions League against Kashima Antlers which ended 2-2 in midweek.
He has gone under the knife in the United Kingdom and the club has posted the development on Instagram with the player on the bed with his right leg heavily strapped.
“Martins had a successful surgery in the UK,” the account wrote on Sunday.
The injury has ruled Martins out of a possible call-up to the Super Eagles for the 2018 FIFA World Cup in Russia in June as he will be out for up to seven months.
Formerly on the books of Newcastle United, Martins has netted four goals in seven games in all competitions in the new Chinese Super League season before he got injured.
