08:08 AM ET 08.14 | New Sixers center Andrew Bynum may show up in Philadelphia a brand new man. [Bynum] will head to Germany in early September to have the same experimental procedure on his knee that Kobe Bryant, Grant Hill and Alex Rodriguez have undergone, according to a West Coast source with knowledge of the situation. Bynum has had surgery on both of his knees. It is unknown whether the procedure will be performed on the one knee or both. According to the source, Bynum???s knees are fine and the procedure is non-surgical. ... The procedure is a derivation of platelet-rich plasma therapy, or PRP. The procedure, which is not yet performed in the United States, is less invasive than many, if not all, other forms of knee surgeries presently used.
