SI.com: Tell me about the platelet-rich therapy you underwent in early January.

Arenas: I had the procedure done on my knees and hips in New York because I kept hearing how much better Kobe [Bryant] felt [the Lakers’ 33-year-old guard had it done on his right knee last June]. So I did my research into it, called the people in Germany and they told me what the process was and what it targeted — arthritis, achiness — and that’s what I was dealing with. So I ended up having the procedure.

By the second shot, I was feeling 10 times better, so I ended up getting six shots and I actually did both of my knees because basically I was favoring one side of the leg for the last couple of years [because of three knee surgeries]. It was six days, every day. And then I came back a week later and had my hips done.

I’m not going to lie, I feel so much better. I’m jumping and moving like before I got injured, like it’s basically ‘06 again. My explosiveness, my jumping ability, my quickness — it feels like I never got injured. I can see why he’s out there doing what he’s doing at his age.
