On Monday (two days ago) I was playing soccer (I play on an in door co-ed league) I was up against the boards challenging a girl who had the ball. I don't remember twisting or anything but I heard my knee crack. That's nothing new my knees crack all the time, but it was a little sore after that. I continued to play the rest of the game with some discomfort, but again nothing major enough to make me sit out. So the next day my knee is really sore. But there is no swelling. However I couldn't straighten it out all the way. I can almost get it straight but I just can't get that last umph. I can force it straight with my other foot, but once I move my foot out my leg falls back to the position it was...Its not painful, I just feel a little discomfort. At times it feels weak, but mainly when I am sitting... I'm walking ok on it, with a limp though because I can't straighten it.

I know a lot of you will tell me to go to the doctor, but I was hoping someone would have had the same thing happen and maybe lead me in a different direction, or at least give me a heads up on what it could be. I tried searching the web but came up with a lot of ACL tears...again though I don't have swelling and I can put weight on it, the only reason I have to limp is because it wont straighten.

SLG,
What you describe sounds like a possible injury to the extensor mecanism of your leg. The main components are the quadriceps muscles, the quad tendon, patella and the patellar ligament as the last link to the tibia.  If any of these is damaged, the extension can not pe performed properly.
There is simple test that you can try, google "straight leg raise" and see what gives.
And, most definitey DO go see a doctor, preferably on Orthopaedic specialist, a general practitioner might not be able to determine much.
Good luck.

I should knoe better than to recommend stuff before trying it myself.
After googling "straight leg raise" I found a test for herniated discs, which is not at all what I had in mind.

Here is what I was thinking about:
1. Lye down on your back, knee completely extended.
2.Try holding your knee straight (180deg) and raising the whole leg without bending the knee.

Another test for the extensor mechanism would be a knee extension against gravity.
1.Sit down on a chair (there should be 90deg flex in your knees).
2. Without standing up, try straightening your knee completely (bring it to 180deg)

Sorry about the confusion.

Thanks...I did the sitting in a chair excersie and I was only able to go about half way...I laid off of sports and any other activity I normally do for a week. After 4 days I could straighten my leg out 100 percent. I still didn't rush into anything because my knee still feels weak at times, but I made it to softball practice yesterday and everything seemed fine. I probably just over streched one of those tedons. I'll be wearing my knee brace for a while...

Thanks again.

It sounds like a very slight partial tare in the quadriceps or tendon.  Here's how I know.  I had a very similar thing happen to me back in 2004.  The lack of extension should have been a clue, but I waited too long for the MRI (3 months).  By then, they found nothing.  By then, everything was back to normal, and I was going everything the same.  I guess I had a little loss of strength and size, but it was pretty much unnoticeable.

4 years later, I ripped it very badly and needed surgery.  When they went in, they told me I had a previous injury, and that had to be the time.  I've learned one thing about getting older.  When you "hurt" something, it really is just a minor level "injury."  Once I made to my late 20's, the days of just rubbing some butter on it or walking it off were a thing of the past.  Where there is pain, there is almost always an injury of some sort.  I kinda thing back of the movie, The Program, when the coach asks, "Are you hurt or are you injured."  There is a difference.  :D
