An MRI exam conducted Tuesday on Andrew Bynum's knees revealed even more problems for the 76ers center, Bynum said.
The results showed new developments: cartilage swelling in both knees and a bone bruise in his left knee, he said. Bynum previously had been diagnosed with a bone bruise in his right knee.
On Tuesday, Bynum visited David W. Altchek, an orthopedic surgeon at the Hospital for Special Surgery in New York. Before Friday's game with Utah, Bynum said he had experienced a setback in his rehab, which the Sixers hope will make him available to play by the middle of January. Bynum said there has been no adjustment to his timetable for a return.
