I wouldn’t be feeling too bad today. That is for having run a marathon yesterday. I have been thinking about what could be my knee pain. I have noted that the pain seems to be a surface issue, not a pain deep within the joint. The other day it occurred to me that it was similar to ITB syndrome except it was on the inside of the knee, instead of the outside of the knee. Well, another key difference is that when you suffer from ITB, it tends to feel fine at the beginning of a run and then at some point during the run it suddenly becomes very sharp and severe. At which point, it shuts you down. My problem, by contrast tends to start tight or it becomes tight within a few hundred yards. Then it loosens up and feels okay. Yesterday, it got achy by 5 or 6 miles, but it did not get too much worse. When I paused for a walk break it did get progressively harder to start running again, but once running it functioned okay.
Okay, so ITB is outside the knee, my pain is inside….. ITB symptoms come on quickly and shut you down, my symptoms ease once I am warmed up, but the area remains achy afterwards for a day or two….. So, how am I thinking that my condition could be similar? ITB results from the Iliotibial Band becoming too tight and causing friction with the outside of the knee. Since I am chronically too tight, especially in the hamstrings, perhaps there is some other band wrapping across the inner knee which is at issue.
I am off today, sitting in my recliner resting my achy knee, icing it on occasion. So I have time for some internet research. Here is what I just found:
That box where it says Pes anserinus is exactly where it hurts…. Clicking around I am finding that tightness in the Semitendinosus tendon, also pictured can cause bursitis pain in the Pes anserinus.
Here is a copy/paste from the sports injury clinic website:
Symptoms of Pes Anserine Tendinopathy
- Pain over the inner, lower knee.
- Pain on climbing stairs is commonly reported.
- Localised swelling.
- Pain on contracting the hamstrings (bending the knee against resistance).
- Pain on stretching the hamstrings.
- Tightness in the three associated muscles.
Pes Anserine Explained
The Pes Anserine (sometimes called Pes Anserinus or the Goose’s foot) is the combined tendon of the Semitendinosus (one of the hamstring muscles), Sartorius (the strap like muscle which crosses the front of the thigh) and Gracilis (one of the long groin muscles). They attach together to the Tibia (shin bone) on the inner part of the lower knee.
In this area there is also a bursa, called the anserine bursa which lies between this combined tendon and the Tibia bone underneath. This bursa may become inflamed due to repetitive friction in sports such as cycling, running and swimming (especially breaststroke). This results in bursitis. Tendinopathy (sometimes called tendonitis) can also occur at the combined tendon and the two injuries may occur in unison.
