Sixers C Bynum sidelined with knee issue

The Philadelphia 76ers announced on Monday that center Andrew Bynum will sit out three weeks as a precaution due to the effects of offseason treatments on his ailing knees.

Bynum, who has a history of troubles with both knees, underwent a radical yet non-surgical procedure, called Orthokine therapy, early last month in Germany, which is intended to treat osteoarthritis.

Though it is not yet approved in the United States, Kobe Bryant, Grant Hill and Alex Rodriguez have all tried it previously. It seeks to produce a high concentration of platelet cells which are believed to speed up the healing process.

The official diagnosis, a bone bruise of the medial femoral chondyle of the right knee, was made by Dr. Jack McPhilemy. Bynum will only be able to participate in low impact conditioning drills for the duration.

With the Los Angeles Lakers last season, Bynum appeared in 60 games and averaged 18.7 points and 11.8 rebounds over a career-best 35.2 minutes per contest. He was traded to the Sixers as part of the four-team deal in August that sent Dwight Howard to the Lakers.

To fill the void, the Sixers signed veteran center Mikki Moore. Moore has averaged 5.8 points and 3.9 rebounds per game with a 55.1 field-goal percentage in 564 career appearances.

The Sixers are scheduled to begin their exhibition slate 10 days from now at Orlando, and kick off their 2012-13 regular season by hosting Denver on Oct. 31.
