Check out this intense analysis on Oden's productivity after MF surgery:
Graphing the time between when the procedure was performed and when the player first returns to an NBA game shows a clear and positive relationship. While the correlation is far from perfect, the trendline shows that on average players lose about 1% less of their pre-microfracture productivity for every extra month spent rehabbing.
This is great news for Oden and the Blazers, who were very conservative following his surgery and immediately ruled him out for the entire 2007-08 season instead of trying to rush him back late in the year. On opening night, Oden will be 13-and-a-half months removed from his microfracture procedure, marking the second-longest rehab on record (Kittles, one of those two players to improve coming back, sat out 16.5 months, making him the top right dot on the chart).
Additionally, that Oden will be able to ease his way back in training camp should be a positive. The way I'm calculating rehab length tends to overstate how long players who come back in camp are actually sidelined because they are testing the knee a full month before the date I use, when they play their first regular-season game. Even with this caveat, players who return in camp still tend to do better than those who return midseason.
Accounting for their lengthier rehabs, the players who come back in camp would be expected to return at 90.1 percent of their pre-microfracture productivity. In fact, they've performed at a 93.0 percent level. Meanwhile, those who have returned midseason have underperformed their expected 85.7 percent of pre-surgery productivity, reaching just 83.7 percent.
Based solely on the length of his rehab, Oden would be expected to lose 4.7 of his per-minute productivity following the surgery. Add in the training-camp factor and that gets as low as a negligible 1.8 percent. Of course, as the first player to undergo the procedure prior to his rookie season, Oden does not have an established level of performance, but his college numbers project very nicely indeed. Using the translation system I introduced before this year's draft, Oden rates as the second-best prospect to enter the NBA dating back through 2000.

Along with Oden's college profile, this suggests that he might need some time to develop into a consistent scorer in the post. However, he should be able to come in and be an elite defender in the middle fairly quickly. In the short term, his recovery from microfracture surgery should be considered a speed bump on his way to superstardom.
