The 48-year-old pachyderm became a symbol of the plight of today's elephants, and her injury sparked international sympathy and donations.
Experts were making a cast of her injured left front leg for a plastic prosthetic limb which will be attached later Saturday.
"I do hope she will accept the new leg. It would be wonderful to see Motola and Baby Mosha walking together side-by-side," said Soraida Salwala, secretary general of the Friends of the Asian Elephant, a non-governmental group.
Mosha, also a land mine victim, became the world's first elephant with an artificial leg, attached in 2007. Soraida said Mosha, now a 3-year-old, is faring well and has outgrown three of her prosthetic devices.
Both elephants have been cared for at the Elephant Hospital, set up by Soraida's group in 1993. The world's first such facility, the hospital has treated thousands of elephants for ailments ranging from eye infection to gunshot wounds.
Motola was injured in 1999 while working at a logging camp along the Myanmar-Thailand border, a region peppered with land mines after half a century of insurgency. Her mangled foot was amputated, and she hobbled on three feet until fitted with a temporary, canvas shoe-like device two years later.
Motola's initial operation used enough anesthetic to floor 70 people - a record noted in the 2000 Guinness Book of World Records.
"It has been 10 years now, but in all these long years Motola enjoyed a happy life, walking out of her shelter for a sun bath," Soraida said.
