LOS ANGELES (AP) — Center Andrew Bynum underwent arthroscopic knee surgery Wednesday in New York, and the Los Angeles Lakers said they expect him to make a full recovery by the start of training camp next fall.

The 30-minute procedure, performed by Dr. David Altchek, consisted of removing some cartilage debris and smoothing some rough spots on the underside of Bynum's left kneecap, the team said.

Bynum hasn't played since suffering a bone bruise in his knee and a subluxation of the kneecap — a brief dislocation that popped back into place — in the third quarter of a 100-99 victory over Memphis on Jan. 13. He was having a breakout season, averaging 13.1 points, 10.2 rebounds and 2.1 blocked shots in 35 games.
