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.
Who are you? Andy Rooney?
Colbert has our backs
K-DUB: I get a chance to see the other MLB clubs Player Development operations out here and I have talked to scouts and other baseball people about it, and I can tell you that the Cubs Player Development program has gone from being almost a joke to one of THE best.
how did ej martinez go from asking for $10m, to supposedly mulling over $7m offers, to eventually signing for $3m?
...and what happened with him and the giants a few days ago?
Its not official until AZ Phil adds him to the Cubs Depth Chart!
Just freakin love it!
From Keith Law:
This from a Kiley McDaniel chat a couple weeks ago...
"Comment From Wrenzie
Who has more ceiling between Yusniel Diaz or Eddy Julio Martinez?
Kiley McDaniel: Martinez. I have Eddy (20 years old) as a 65 runner with a 55 arm and 50 raw power that profiles as an everyday CF that could be above average depending on if the bat is a 45 or a 55. I have Yusniel (19) as a 60 runner with a 55 arm and 40 raw power that can be an everyday guy if he hits enough (50 or 55)."
"Per Jesse Sanchez at mlb.com, Cubs reportedly have signed 20-year old Cuban OF Eddy Julio Martinez for $3M bonus.
Arizona Phil 7 hours 23 min ago"
it's day old news, and it's got nothing to do with the cubs, but ichiro signed a $2m deal with MIA (with a $2m option for 2017).
neat. 41 years old and damn close to 3000 hits.
also, rain delays suck.
take that giants
I think that if a team objects to the 1-game wildcard playin game so much, they could just win the pennant and avoid themselves the trouble.

BLOCK: Of course any advantage is an advantage. An MLB, NBA, or NHL team getting the extra game at home in a seven game series is an advantage, I just don't think it is enough of an advantage for winning a division and/or having the best record in a conference or league over the course of an 82-game season (NBA and NHL) or 162 game series (MLB).
TEX takes the opening game from TOR (@TOR) 5-3.
TOR lost bautista + donaldson in-game due to injuries...TEX lost beltre...dunno if any will be lingering issues leading to missed games.
Ride the Kid Magic! Schwarber hadn't homered in a long time before last night.
