Every time I try to perform an intense interval session, I get pain in a very small spot on my left knee. Feels like a concentrated sharp pain (3/10) top lateral corner of my kneecap. Pain goes away after 2 days. It doesn’t hurt on the bike, starts a few hours after the workout. On the bike there is no pain. I have no problems doing 4 hour rides outside or tempo ride inside without pain with double or triple the TSS. It’s come to a point that I just avoid intervals completely for the last few years. I do value being able to ride outside comfortably for 4 hours rather than improve my FTP. But can I really just improve by doing tempo and endurance exclusively ? Or should I try to fix this issue?
Could be IT band or LCL problem. Have you seen a good fitter about this ? Seat height maybe.
I had knee pain located in front of the knee after hard steep climbing. Being older my analysis was a tendon or ligament issue. Added collagen before my rides. After about 6 months I was able to climb steep hills again. Don’t known if the collagen was what helped it heal.
It’s not on the side of the kneecap. Probably the insertion point between the quad tendon and the kneecap. But only in one small area. Have seen a fitter a few years ago but this came up few years after.
