I’m sure most, if not all of you who read my blog, know that I have a bad knee; a knee which I injure too many damn times, and therefore must have something wrong with it. It’s my right one, specifically, you know. The one I strain my tendons and ligaments in all the time? One wonders why I haven’t blown it yet, like destroyed my ACL or something.
Anyway, this morning I had Kinesiology lab and were were doing Manual Muscle Tests (testing a specific muscle group for strength and to see if there’s any pain, if there’s any at all) and goniometric measurements of the lower extremities (lower body, feet to hips, basically). Anyway, setting aside my minorly sprained ankle (which I may tell you about in a minute), I made a discovery about my knees.
Goniometry is the measurement of angles, basically. In kinesiology’s case, the angles are our joints, thus we’re measuring the range of motion of that joint. When measuring the knee, the start value is our knee extended, straightened, but not fully extended. When we measure the full extension of the knee, we’re measuring how much it hyper-extends. Sooooo, I got my knees’ ranges of motion measured.
When you measure the degree of extension when it comes to the knee, you prop the foot up on something — a sweatshirt, a book, something similar — and allow gravity to pull your knee “backwards” until it locks. My left knee was relatively normal, it’s extension range of motion was 3°, a relatively normal range. My right knee, on the other hand, was a completely different story.
When we propped it on the sweatshirt, it didn’t lock. This meant that it wasn’t fully extended. So, I tried to adjust my foot’s position, but by the time she actually took the measurement, it still wasn’t fully extended. But even with it not being fully extended, the measurement we got was 19°. So, I’m saying that my estimated ROM for my right knee is at least 20°. One of these days, I want to get a more accurate measure.
So, it totally threw me off when I found out my right knee was about 16° more extensible than my left knee. When I thought about it, I figured hey, maybe that’s why I’m having ligament and tendon problems with my right knee, and maybe that’s why I always hyper-extend my left.
So, anyone else have any thoughts to add to this? Any questions you might want to ask? I’ll answer what I can. So be sure to check your comments, because I don’t think I have a plug-in that notifies commenters if/when their comment is replied to.
Oh, before I go, I said I was gonna tell you about my ankle, right? Well, if I didn’t who cares? I’m telling you anyway!
Okay, so, last Friday, some of the female members of the track team met up to play Ultimate Frisbee (I’m not running track this year, unfortunately, so Coach probably hates me…). It was really fun and all.
So the field we were playing on, one of our endzones was actually sloped a little. You can sort of see where this is going. Well, towards the end of our scrimmage, I was on offense cherry picking the end zone. Kris… Kristen (?) threw me the frisbee, and I turned to try and catch it. When I missed, I turned back around and rolled my ankle REALLY bad. I felt a small pop, and it hurt like a BITCH for a while. I walked back over to our end (because we eventually scored), rubbed it a few times, and then shrugged it off and continued playing. While it didn’t hurt all that much (or maybe it did and I was too focused on the game to actually notice) during the game, when I finished eating and went back to my room, it was killing me. Later that night, it was swollen. With the advice of my good friend Steve (yes folks, he’s still very much alive), I propped it up on my desk and the swelling did go down.
I’m checking my ankle right now and… it looks like… there’s no swelling. But occasionally, when I walk, there’s a shooting pain that goes down my talus, and sometimes on the underside of my foot too. It’s not a crippling pain, but it’s noticeable enough to be annoying and slightly painful.
There you have it. Okay, leave comments with theories and questions if you have any. I’ll reply and answer what I can.

? And track has a meeting tomorrow. I decided I’m only going to run outdoor, because I hate running indoor (it probably would have been different if I had ran indoor track throughout my high school career instead of just starting to run it my freshman year in college).
