I started having pain near my patella tendon this past January after barely leaving the house that particular day, got so bad I could barely bend it the next day. I religiously iced and babied it for 10 days and it was getting “better” and one day I was walking and felt a sort of slight pop in there like something moved or shifted and 10 minutes later I was walking normal, could run again, etc. Was great for about a good month and I woke up one morning to a sore knee again but in a slightly different spot (at the bottom of patella rather than side). Did the brakes on my car that day and had to use a pad to kneel with that knee but by the next morning it HURT and I could barely move it and it was so swelled up. I fought it for about a week and went to doctor and they thought I had an inflamed bursa sac.
Fast forward bit, I’ve been fighting this for over 3 months and I’m about 2 months into PT for “patellar tendinopathy” (or so we think) and the knee is still swelled up, I can’t run at all much less walk up steps normal, and it’s really frustrating. I’ve had a lot of muscle loss in my quads due to lack of use in that leg and my patella had unlearned engaging on its own so been doing a lot of exercises to combat that. I seem to have made progress but the instability and sudden give outs are still there and I’m Not gaining noticeable muscle back at any good rate (granted my PT warned me this would be a long road to recovery). I did have a similar feeling and flare up with pain in this same spot in 2018 that magically disappeared after about 3 weeks and historically this is my “good knee” unlike my other that had football injuries.
I’ve since decided if I’m not a lot better by the end of July I’m going to see an orthopedic specialist and probably get MRI or whatever. I can’t run rely to the OPs frustrations as I fear I may need a new knee but also think I might just have something floating around in there that has caused most of this. I managed to hobble around and catch about 80 beaver this spring and that was much more of a shore than it usually would be with not being able to kneel on my right knee and the walking instability. Somewhere toward the end of beaver season it was borderline getting better and I was borderline running through a swamp and tweeted it slightly which I know was not smart (but it was feeing “better”!). Good luck and Happy trapping! ScottW
