About a year ago, I decided to get a really hard workout by riding my mountain bike (on roads with slight inclines) for 20 minutes straight - I didn't work up to it at all (but I'm young and invincible, of course). Afterwards, my left knee began hurting. Every time I ride my bike or go up stairs, it aggravates my knee. The pain is just above my knee cap down inside my knee a little bit. Is this my ACL likely? Can I rehabilitate it without surgery? I have found that when I jog my knee feels a lot better for the rest of the day.
Hey man. I had the same problem about a year ago, I was running though. I had recently increased by mileage and my knee started to hurt. Then my pt said that my patella(or my knee cap) wasn't tracking right, causing pain, and through stretches, deep tissue massage, and quad strengthening exercises it would get better. So it's probably nothing too serious.

I think I know what your problem is.
doesnt sound like an ACL to me.
sit down and put your leg out on a chair so that it's stretched out straight. Have a friend squeeze your leg just above the knee while pushing on the kneecap. He should push from the outside of the leg toward the center. At the same time, tighten your thigh muscle. If this is painful, you have a problem.
If so, you have something called "patellofemoral pain"...otherwise known as "runner's knee"
The exact cause isn't always immediately known, but usually has to do with the way the kneecap rides in the groove of your femur.
It can be caused by a BUNCH of things. These are usually the prime suspects:
Weak quad muscles, tight hamstrings, a tight iliotibial band, and gleut muscles that are too tight, as well as an improper gait. The last bit means that something is wrong with the way you walk or run, but can also cause problems while biking if your feet and ankles are forcing your knee joint out of alignment.
If this is the case with you, proper stretching before riding is a good idea. Stretch your quads, calf muscles, hamstrings, and buttocks. After you ride, ice down your knee for a bit.
If the pain doesnt get better, see a doctor.
Since your description is not very clear, I will present you with another possibility:
Iliotibial Band Syndrome. This is actually more common in bikers than runners. Pain is usually felt laterally to the knee and above it. (above the kneecap and slightly to the ouside)
In the case this is your problem, the only solution is to stop biking for a month or so until it gets better. If after a month you resume and it still hurts, you need to see a doctor.
