The 76ers announced Monday that center Andrew Bynum will not participate in basketball activities for the next three weeks to "maximize the therapeutic effects" of the non-invasive procedure he underwent on his knees last month.

Bynum said that he "felt some discomfort" on his knees - both of which received Orkathine therapy - and that the team had decided that rest, as a precautionary measure, was required.

"I was working out and kind of told them I was feeling uncomfortable, and they said take time to let the procedure work," Bynum said.

Bynum was examined by team physician Jack McPhilemy and was also diagnosed with a bone bruise to his right knee. Bynum said that the two issues are not related.

Asked if he should have opted to have had the procedure done earlier, Bynum said he was told by the physician who performed the procedure, Peter Wehling, that it was best to have the procedure done right before training camp.

Orthokine therapy involves injections of plasma-rich platelets designed to stimulate healing in area affected by arthritis.

Bynum, who turns 25 later this month and is entering his eighth NBA season, has had knee issues during his career. But last season he played in 60 of 66 regular season contests and 12 more in the postseason.

"It's definitely disappointing, and I want to be out there playing," Bynum said.
