During the 2005–06 NBA preseason, knee cartilage damage was discovered and Stoudemire underwent microfracture surgery on October 18, 2005. Initially, the Suns thought he would return by mid-February, but his rehab took longer than expected. Stoudemire, however, scored 20 points in his return against the Portland Trail Blazers, but went scoreless his third game against the New Jersey Nets on March 27, 2006. On March 28 it was announced that he would likely miss the rest of the regular season due to ongoing stiffness in both knees. His manager stated that the comeback came a little too soon, and Stoudemire needed to do more rehab. Stoudemire's rehabilitation, which was led by Suns trainer Aaron Nelson and Dr. Micheal Clark, the president and CEO of the National Academy of Sports Medicine (NASM), went well as he stated during the rehab that he was explosive and he gradually gained his strength back.
