The Portland Trail Blazer center Greg Oden is out for the season again as a result of knee injury. It is fairly obvious that Oden's congenital makeup other than his height did not set him up for professional sports and especially basketball, where the load on the knees is significant. He has undergone a second microfracture surgery on the affected knee and has had a similar procedure done on the other one. The nature of this surgery is essentially to create small fractures in the bone around the joint which causes the marrow in the bone to "bleed" in essence a stem cell version of the cartilage that provides the cushion and glue that holds the knee together. This procedure is most often done in patients that require joint replacement as an alternative. The healing time is similar to a hairline fracture which can be 3-4 months before significant improvements in the ability to bear weight and regain function return. Thus Oden is out for the season again and with the repetitive nature of this injury and the degenerative condition that follows, it can be predicted that his career as a productive center in the NBA is in doubt.
