What with the gas tanker exploding and everything else going on, it was almost a footnote, but Grey's Anatomy fans have a chance to get some closure on that TED Talk Dr. Callie Torres agonized over throughout Season 9 Episode 19.

It turns out that the UA has the real guy, John A. Szivek, PhD., doing the real um, cutting edge, cartilage engineering, and he's going to tell us, probably exactly, what Callie would have told Ted had she known what she was talking about. He's presenting "Building Better Joints: The Future of Cartilage Tissue Engineering" at 6 p.m., Wednesday, June 5, in Room 8403 of the UA Medical Center, 1501 N. Campbell Ave.

Details after the break.

To recap, Callie was in knots over her presentation while her wife, Arizona, tried to help in all sorts of novel ways, including getting naked. Crises at the hospital all but blew up Callie's star turn on TED, but hospital honchos set up a remote broadcast and in the closing scene, our heroine began lurching into a heartwarming talk about togetherness and cartilage engineering.

She must have learned it all from Szivek, who, with his team, leads internationally recognized research in the field from his Orthopaedic Research Lab at the UA Health Sciences Center Department of Orthopaedic Surgery. You can check it all out on his website, research.bones.arizona.edu (yes, really). His June 5 presentation is part of a series called Living Healthy With Arthritis, hosted by the UA Arthritis Center, where Szivek is senior scientist.
