Darwin Barney's Pacific Coast League (PCL) Sprain
Darwin Barney went on the DL this week spraining "the other" cruciate or Posterior Cruciate knee ligament. I'm sure the Cubs called Iowa Cubs manager Bill Dancy to let him know that his Pacific Coast League (PCL) Iowa team might shortly be getting another middle infielder on rehab assignment for his lineup. Barney sustained the injury to his right knee on the play at home plate on Monday night, scoring the Cubs only run in a 1-0 victory. It looked like he bounced his knee in the dirt during a head first dive and he did stumble a bit getting up from his dive. The MRI showed injury without stretch (grade 1) to his Posterior Cruciate Ligament (PCL). This is considered fairly minor but probably needs to be protected from further injury for about 2-3 weeks.
"As soon as I slid into home plate last night, I knew something was really wrong," he said. "The whole knee went numb. I had an MRI today and it revealed that Grade 1 strain in my knee." (editiorial note: ligament injuries are sprains, muscle injuries are strains)
Right now Darwin Barney can't jump, but you can. So read more after the jump.
There has been plenty of media attention paid to the Anterior Cruciate Ligament (ACL) which when torn in a high performance athlete is treated with reconstructive surgery but little is written about in the media when the posterior cruciate ligament (PCL) is injured. The Posterior Cruciate is structurally the more robust of the two cruciates and isolated PCL injuries can occur but are less frequent and usually produce more subtle symptoms. If both the Anterior and Posterior Cruciates are torn, more drastic instability can occur including knee dislocation but fortunately that is not very common. Most people hear about the fairly common patella (kneecap) dislocation but a true knee dislocation (tibia-femur) is a severe injury and acute knee dislocations can even have nerve and artery damage.
The PCL attaches behind the knee on the tibia and goes to the medial (inner) side of the central notch on the femur. The ligament prevents posterior translation of the tibia relative to the femur above and also provides central rotational stability. Here is an excellent 3D modeling video of the PCL including how the ligament works in flexion and extension of the knee. The Anterior Cruciate (ACL) attaches to the anterior tibial spine near the front of the knee and goes to the lateral (outer) part of the femoral notch. The ligaments cross (hence, cruciate) each other and protect and stabilize the knee when working in tandem from excess rotation and translation.
Before MRI imaging was available, grade 2 vs 3 PCL injuries were sometimes subtle to diagnose on exam with what was called a "posterior sag" sign with the knee extended or a "posterior drawer" sign with the knee flexed. The PCL does image well on MRI studies (see "P" on image), so seeing injury to it (because the tissue signal is altered in injury) is straightforward making even subtle grade 1 injuries possible to diagnose these days.
The most common mechanism of injury is a direct blow to the front of the upper tibia, which is what seemed to happen to Barney's leg in the head first dive at home plate.
Certainly, a grade 1 strain should respond to rest and rehab in a few weeks but when the PCL has a third degree injury and the knee has instability there are arthroscopically assisted surgical reconstructive techniques (see video) available. These have evolved and are significantly improved over the last 2 decades and much of the technology has been based on arthroscopic considerations for the ACL which is now a frequently performed surgery. Brewer ace Yovani Gallardo tore his ACL in May 2008 (against the Cubs avoiding contact with Prince Fielder on a Reed Johnson bunt) and was able to come back to pitch in late September and started a playoff game vs the Phillies that season. The injured PCL has better blood supply than the ACL and therefore can heal without subsequent instability. The PCL is much less frequently reconstructed (than the ACL) and often has several other associated injuries including the ACL and meniscal tears making any associated instability more extensive, so the results are more difficult to assess and should not be compared to the more common anterior cruciate ligament reconstruction outcomes. I don't know of any major league players that have needed PCL reconstruction although I would be interested to hear if any mlb player has had this done.
I wonder if Doc Gryzlo will recommend a few games of rehab in the PCL for Barney's PCL once the swelling and soreness improves.
This all assumes Chapman doesn't want to be a free agent and possibly sign a $20MM+/year deal. We all know free agents get overpaid, sometimes dramatically (Hello, JayHey!). Not sure why Chapman would agree to the extension. If i'm is agent, I would tell him I could get I'm a $100M deal as a FA.
I'll root for the uniform and imagine it's left-handed Rod Beck or Randy Myers out there I suppose.
Amen to this. I guess it's gonna happen and I'm gonna have to suck it up but I really despise domestic abusers with every bone in my body and cannot stand them on any team I root for.
I just prefer they don't acquire players that choke their wives/girlfriends.
So you'd rather go with Blown Save guy, when you can trade a prospect who is blocked for one piece that could get you over the top to the Big Dance? That is pretty old thinking. This is not a move that they cannot recover from if it goes south. But the upside is potentially historic.
I'd prefer it not happen too.
it's a hell of a blockbuster, but it's for a guy who pitches 1/3rd of a season at an extreme premium considering the guy being traded and if the early extension $$$ rumors are true.
it's one of those things that is bringing a guy at the top his game, but something is nagging me that this trade piece could have been put to better use.
a huge part of me is all "hell yeah, top of the line producer"...another part of me is "hmm, that for that?"
Still don't want. Kinda hope they can't work out the extension.
obviously not, and I'm sure they did their homework...just hope they have some better answers than the Yankees
Chapman 12+ Career WAR. Currently 4.7:1 k-BB. With Rondon/Chapman/Strop/Nathan/Montgomery/Wood...Its the best pen I can recall other than Sutter or Lee Smith handling things themselves.
Its gonna suck if he gets injured, and it appears he's not the greatest of characters.
But, he'll have another Cuban to hang out with on the team.
I agree with the names you mention but there are lots of names being tossed around still and there's that small matter of Chapman agreeing to the extension.
Heyman, Wiatt, and Sharma are definitely reliable sources. Wiatt and Sharma have a ton of connections with the FO, and Heyman is one of the national guys who usually breaks stories first along with Rosenthal and Passan.
Twitter is even more nonsensical with names and rumors than usual right now. I'd wait for a real confirmation from someone reputable at this point before getting too worked up.
a'ite then. i mean, at least they're getting one of the best at a young/durable age even if there's a heavy price to pay for it.
i pretty much assumed this would be one of the last kinds of things they'd do...give up a top prospect (probably the best in the system) to get 1/2(ish) year of a reliever followed by multiple years locked in at his market value.
i wonder if there's other players going back/forth, too.
i mean, it's not like it's a horrible thing...this is just something that seems out of profile.
Suspend him for the rest of the year and get him ready for the Schwarber era?
