Hi there,
I've been struggling with knee pain for the last year and need some help. I've been through a couple of orthopedists and PTs, leaving them all confounded as to what is causing my pain.
It started a year ago after I increased my mileage (though still very low, 15 m/w), including some longer hill runs. It seemed at the time to be clearly patellar tendonitis, as the band right below my kneecap felt very sore after runs, particularly if I squatted down or descended stairs. Eventually I had to stop running entirely, and aside from a few trials I really haven't run since. I find other ways to exercise, but avoid activities with much knee bending.
The pain now is a bit different, perhaps more in the PFS space. It hurts on the lateral 1/3 of my kneecap, and will swell to a bump when irritated. I can cause the pain by pushing my kneecap over from the lateral side, then pressing down with my fingers. It seems to tolerate flat walking or biking okay, but if I do something with deeper knee bend or more intensity (squats, lunges, leg extensions, hilly biking, descending on foot) it gets aggravated, usually later that night once I stop moving it.
Doctors I have seen have not found any smoking gun. No clear weakness or muscle imbalance, despite very limited quad work over the last year. I've had an MRI and nothing shows up there either. By all accounts it appears to be a healthy knee. I do have some general issues that may play a role:
1) My dorsiflexion is bad. Worse on the opposite side, where a couple of ankle surgeries leave me pretty limited. But below average even on the "good" side.
2) I'm one of these tall, lanky guys with a tight rear kinetic chain. Despite regular stretching my hamstrings, calves, and quads are somewhat tight. My hips, however, are reasonably flexible. I'm good at figure 4 or pigeon, for instance.
3) I have high rigid arches and plantar-flexed first ray that cause me to supinate. It's worse on the opposite side (no coincidence, the one that needed ankle surgery). I have orthotics that I think do a pretty good job of correcting this.
Most of the PT I've done has focused on strengthening things. I've done a bunch of hip strengthening, but no impact on my pain. I've tried to do quad strengthening, but any time I advance past really easy stuff it gets irritated again. I've also worked on improving dorsiflexion, but I expect gains there will be limited. I did get a PRP shot in the knee that may have helped somewhat, but definitely didn't do the trick. We've also done some scraping of the area lately, but it's getting hard to find "crunchy" areas now. My orthopedist suggested a cortizone shot, but I'm just worried it will only mask the symptoms for a few weeks.
The pain is mild most of the time, but after a year largely "off" I'm amazed that it still flares up every other week or so due to some long walk or mild activity with my kids. I've dug around on this site but most of the posts on this subject are 14 years old and describe cases that merely required reducing mileage rather than stopping altogether.
Hopefully this way too long post will spark some ideas from the community. Thanks for reading.
