49ers rookies: Marcus Martin November knee injury appears to be behind him

San Francisco 49ers rookie center Marcus Martin suffered a knee injury last November. He appears to be past it, but it's still worth a look.

This past May, the San Francisco 49ers drafted several players with notable injury concerns. This group consisted of three ACL injuries, including Brandon Thomas, Keith Reaser, and Trey Millard. The 49ers will redshirt at least two of these players, with Millard a likely candidate as well. Jimmie Ward is in the midst of recovering from his own foot injury, for which he had surgery back in March. He was limited in the offseason workout program, but the general belief is he will be good to go in time for training camp.

One other player that suffered a 2013 injury that we overlooked was Marcus Martin. In the Martin 90-in-90 post yesterday, I had dropped a link in the comments to a Conquest Chronicles article. That article mentioned a "gruesome injury", as pointed out by BigMar. I had overlooked that previously, but did some research last night.

On November 30, 2013, Martin suffered a knee injury in USC's regular season finale against UCLA. There was no official word on the injury. Three days after the injury, Scott Wolf reported the injury would not require surgery, but that it would sideline him 2-3 months. It was eventually reported as a dislocated kneecap. Martin did not run the 40 at the NFL Combine, but he did return for his own campus workout.

Knee injuries are always something to be wary of, and a dislocation can be tricky since it could lead to future dislocations. The good news is that the team had Martin actively involved in 11-on-11 drills at minicamp. The team is conservative with players when it comes to the offseason workout program. Considering it consists of no live contact and no pads, it makes sense to play it safe. The fact that he is involved in full drills is significant, and would seem to indicate he is pretty much fully past his knee injury.

Although it would appear things are moving along just fine, I still wanted to get socalisteph's thoughts on the injury. She mentioned that the knee cap is necessary for the stability of the quadricep, and that it helps stabilize the leg, particularly when it is extended. When someone suffers a kneecap dislocation, there can be nerve damage that can result in something called "foot drop". That can result in dragging the foot. However, given that the team has him back in normal workouts, it would appear he has made a strong comeback.

90 percent of the time the injury heals perfectly fine, but there is always that small chance of a problem. In this case, that would not seem to be an issue. The key is to avoid damaging the supporting structure, which means you have to be careful when it comes to bearing weight. He likely wore some kind of brace to immobilize it initially, but once it heals, you can pretty much return to full use. There is always the concern of another dislocation, but as long he is technically sound, it's not something to worry too much about.

Back in February, Martin posted this picture on Instagram with the caption, "They said I wouldn't squat ,They said I wouldn't run , They said I Wouldn't be ready , YEAH RIGHT! Thank you Ruz and Dr.Pat #GRIND #GODISGREAT"
