Post from my blog. Thought I'd share.

All Colston owners (including myself in two of seven leagues) gasped on May 26, 2009 when hearing that Marques Colston underwent microfracture surgery on his left knee in January 2009. It was a far cry from the "routine surgery" originally reported. I was particularly pissed after dealing Eddie Royal and the equivalent of an early 2nd round rookie pick for Colston a week prior in one of my main dynasty leagues. Being a vested owner and reading some speculation from other fans that Colston may be done for the year or not play a full season, I decided that I'd research and see how successful NFL players have been in recovering from this surgery. My hope: analyze the impact on a young Colston (26 years old) for 2009 and how it will effect his dynasty value.
An important point to note is that Colston also had arthroscopic knee surgery (also his left knee) back in the 2008 offseason. Typically, microfracture surgery is also needed as follow up to a knee scope since the scope removes torn cartilage and the microfracture surgery replaces the cartilage.
Surgery Background
According to MedlinePlus, which is a service of the US National Library of Medicine the procedure consists of the following:"The surgeon uses a small pointed tool called an awl to make very small holes called microfractures (tiny breaks) in the bone near the damaged cartilage. The holes the surgeon makes in your bone release the cells in your bones that build new cartilage."
Through my research, I learned that microfracture surgery is often successful in all patients (not solely atheletes). Here is a nice link with more information on the procedure and success rates. The most intriguing information from this link is that "current studies have shown a success rate of 75 to 80 percent among patients 45 years of age or younger, even among professional athletes. With the help of physical therapy, patients can often return to sports (or other intense activities) in about 4 months. " One concern, however, is that the new cartilage often is not as strong as healthy knee cartilage since it's more brittle and susceptible to breaking down in the long-term.
Recovery typically ranges from 3 months to 1 year and is contingent upon the severity of the surgery, size of the incision in the cartilage and the location of the incision. Unfortunately, this information isn't available to the casual fan for analysis, but it is relevant information.
Microfracture Surgery & NFL Players (Active & Retired)
Given that the information above focuses on all patients including your "Average Joe", I thought it pertinent to take a look at the success rate in NFL players. Interestingly enough, a majority of the population consisted of non-skill position players or aging veterans. I'll walk through the players that I found and note the relevance of each.
Kellen Winslow
In January 2007, Kellen Winslow had microfracture surgery on his knee at the age of 23. Winslow recovered quickly and had his best season as a pro in 2007 with 82 rec., 1160 yds, 5 TDs. Very similar position to Colston and roughly the same age, which could be indicative of Colston's recovery. Two potentially indicative points to consider: 1) Winslow successfully returned to All-Pro form, and 2) Winslow recovered quickly after having surgery in January 2007.
Stephen Davis
Davis had surgery in November 2004 at the age of 30. He played the following season in 13 games with 180 car., 550 yds, 12 TDs. He soon fizzled and retired, but that doesn't appear to be solely a result of his surgery after performing adequately in 2005. The contributing factor was more likely his career carries and the related wear and tear on his body. I can't say the surgery didn't impact his longevity (because I am sure it did), but the fact that he was 30 when the surgery was performed and had roughly 1800 career carries, it carries less weight when comparing to Colston since Colston is still a very young NFL player/athlete. However, I will consider two items: 1) he successfully returned the season following surgery, and 2) His career was shortened.
DeShaun Foster
Is there something in the Carolina water? In November 2002, Foster had microfracture surgery prior to having an NFL carry. Foster had the surgery at the age of 22, recovered and played in the 2003 season. Foster was never a phenomenal pro; he annually fell short of 1,000 yards rushing. This may be a result his lack of talent and not limitations as a result of the surgery, but we'll never know since the surgery was his rookie year. Two important points here: 1) He successfully returned from surgery (positive for Colston) at the age of 22, and 2) He recovered in approximately 1 year (rather long time for recovery).
Courtney Brown
Brown had two microfracture surgeries and three knee surgeries on his left knee (2002 and 2006 microfracture surgery). He successfully returned from his first surgery in 2003, however, he was never able to successfully return to the field after his 2nd surgery in 2006. The second surgery was likely needed because the cartilage in the initial surgery wasn't as strong as true knee cartilage. This, as discussed above, is a long-term problem with the surgery. This comparison in particular is striking to me and I'll carry weight on two points: 1) He returned triumphantly after one surgery (2003 was a decent year for Brown), and 2) his second surgery ended his career after apparent deterioration in his knee.
Fred Robbins
Another big man with microfracture surgery this offseason. He's still rehabbing and there's limited information available currently, except that he's no guarantee to be ready for training camp. Robbins is 32.
Jeremy Newberry
Newberry had multiple microfracture surgeries. He had his first following the 2005 season on his right knee at the age of 29, missed the 2006 season and had another surgery on his left knee after the 2006 season. In 2007, he started and played in 14 games for the Raiders, more recently was a backup for the Chargers in 2008 starting 3 games (age 32) and signed with the Falcons this past offseason. Two important points again: 1) he was able to successfully return from his first surgery, and 2) these surgeries appear to have slowed his career down limiting him to a backup role at the age of 32.
Patrick Jeffers
Jeffers had microfracture surgery in 2000 (he also tore his ACL at the same time) and his career was finished. He continued to have swelling/pain in his knee after playing his final game in 2000 at the age of 27. This is a tough one to consider since he also tore his ACL at the same time, but it's definitely troublesome that he never returned to play the WR position.
Other Professional Athletes
What's so interesting is that there are a very limited number of NFL players who have undergone microfracture surgery. Amar'e Stoudamire, Jason Kidd, Kenyon Martin, Antonio McDyess and John Stockton all had microfracture surgery and successfully returned. Several other players, such as Chris Webber and Afernee Hardaway returned, but were clearly limited by the surgery.
Analysis
Unfortunately, there's no definitive conclusion from the above (and my other research) that will help in pinpointing Colston's future success. It appears that each individual will respond differently depending on the degree of the surgery and his/her body's condition. I'm no medical professional and don't have access Colston's health records to determine the severity of his surgery. However, Colston has been back at practice, and there are some clear patterns and information that we can apply in order to make informed decisions for our fantasy teams. I see the following:
1) The knee scope from last year and the microfracture are related and a typical sequence of events. Removal and replacement of cartilage. This really isn't two separate knee issues.
2) Winslow may be the most relevant comparison given the age and the proximity of the surgery year. He successfully returned after a short rehabilitation period and performed at a pro bowl level. Colston's surgery was in Janaury much like Winslow's. With Colston already back in camp, he should be ready for the start of the 2009 NFL season.
3) From the background info and C.Brown, the replacement cartilage clearly breaks down and stunts an athlete's career as a result. In my book, this is a decent hit to Colston's long-term value or dynasty value.
4) Jeffers is one of the few younger players that was not able to return to play. However, he also tore his ACL in 2000. There's also a number of legal proceedings currently in progress regarding this surgery and potential malpractice by the Panther's team physician. With Colston at 26, the odds of his recovery are in his favor.
5) If Colston's new cartilage wears away and he has another microfracture surgery, I'm selling ASAP and steering clear. It may be the end of his career if it hits this point.
Final Conclusion
The younger a player is from the examples above and the background info, the more likely he is to return to form (which makes sense). At the age of 26, Colston should be able to continue to perform at a high level beginning in 2009.
This clearly makes Colston a target for me this season and the apparently already successful return from his offseason surgery. He has the potential to have a top 5 season. Redraft... buy/draft. Let the others worry and he'll fall right into your lap.
However, regardless of him returning to form this year, from a longevity standpoint, I see a stunted career. He's highly unlikely to have a TO, Jimmy Smith or Derrick Mason 10+ season career. I have not yet found an NFL player who continued to perform at a high level for a significant period of time following the surgery (though, again, it is a small sample size). From a dynasty perspective, he's dropping in my rankings purely due to the uncertainty of the long-term impacts and the unclear long-term effects.
Buy now, sell in the short term after a huge 2009! He sure as hell has the talent. That knee better just hold together for another year or so.... it should.
