There have been many notable professional athletes who have undergone the procedure. Partially because of the high level of stress placed on the knees by these athletes, the surgery is not a panacea and results have been mixed. Many players' careers effectively end despite the surgery. However, some players such as Jason Kidd, Steve Yzerman, John Stockton, Kenyon Martin and Zach Randolph have been able to return at or near their pre-surgery form while players Ron Harper, Brian Grant, Chris Webber, Allan Houston, Penny Hardaway, and the late Derek Smith never regained their old form.[9] Others such as Jamal Mashburn and Terrell Brandon never recovered and retired. Portland Trail Blazers rookie Greg Oden underwent the procedure on his right knee in early September 2007 and missed the entire 2007-2008 NBA season. At only 19 at the time of the surgery, doctors were confident that he would return to at or near full strength by the 2008-2009 season; he had a second microfracture surgery, this time on his left knee, in November 2010. Subsequently, Oden has not returned to the NBA, missing the entirety of the 2011-2012 and 2012-2013 NBA seasons. The San Antonio Spurs player, Tracy McGrady also underwent microfracture surgery, doctors were confident that the 2 time scoring champion will return to full strength. As of 2012 he has not had the same speed and jumping ability as he formerly did.
In October 2005, young star Amar'e Stoudemire of the NBA's Phoenix Suns underwent one of the highest-profile microfracture surgeries to date. He returned to the court in March 2006 and initially appeared to have made a full recovery, but subsequently started feeling stiffness in both knees (his right knee had been overcompensating for the injured left knee). He and the team doctor decided he needed more time to rehab and he did not return until the 2006-2007 NBA season During the 2006-2007 season, Stoudemire returned to form, averaging 20.4 points and 9.6 rebounds per game while playing in all 82 regular-season games and the 2007 NBA All-Star Game. His recent success has brought positive publicity to the procedure, further distancing it from a previous reputation as a possible "career death sentence" in the sports world, though he was one of the youngest of the aforementioned players to undergo the surgery.
In June 2010, Grady Sizemore of the Cleveland Indians underwent microfracture surgery after injuring his left knee while diving back to first base earlier in the season. Sizemore was re-activated as the Indians center fielder in April 2011, ending an 11-month stretch of being disabled due to his injury. In his first game back on April 17, 2011 Sizemore showed no signs of slowing down as he had 2 hits in 4 AB which included a double and Home Run. Currently, Sizemore is the only player in MLB history to come back from knee microfracture surgery and play centerfield.[
