Colston had a similar operation on his left knee prior to the 2009 season. He was ready for training camp that year and the Saints leading receiver told the paper he is ahead of schedule this time around.
"I'm doing everything now. It's just about getting my conditioning back," said Colston.
Colston, who also had surgery on one of his wrists this offseason, said the knee injury bothered him for most of the season until the pain became unbearable following a Week 16 win over the Atlanta Falcons. Colston had minor arthroscopic surgery after that game to clean up some loose cartilage that allowed him to play in the Saints playoff loss to Seattle, but said he always knew he would have to have more extensive surgery on the knee.
Colston finished 2010 with a team-leading 84 receptions for 1,023 yards and seven touchdowns.
Also recovering well from offseason surgery is Saints receiver Robert Meachem, who had an operation resolve nagging pain in his left ankle. Meachem also a regular at the Saints' Tulane workouts, said the ankle is "ten times better."
Meachem caught 44 passes for 638 yards and five touchdowns last season.
