Howard, who will become an unrestricted free agent this offseason, was examined on Wednesday by Dr. James Tibone of the Kerlan Jobe Orthopaedic Group.
"I'm going to do whatever I can to get myself right this offseason," Howard said at his exit interview Tuesday. "Last year, I didn't have the opportunity to get in the gym once before the season. I didn't have the opportunity to grow and develop as a player, but that's something I'm looking forward to."
Howard spent last summer away from basketball while he rehabbed from back surgery.
His shoulder was first injured in a Jan. 4 game against the Los Angeles Clippers, forcing him to miss a total of six games.
In his first season with the Lakers, Howard averaged 17.1 points and a league-leading 12.4 rebounds per game for a team that was decimated by injuries and swept out of the first round of the playoffs by the San Antonio Spurs.
