Wow, Bill, a matching set of knee replacements, you're a warrior, man! Mad respect for getting back on the bike after all that. It's awesome you've got nearly full range of motion back, that's huge. It sounds like you're doing all the right things with the PT and quad sets. That persistent tightness in the VMO and Vastus Lateralis can be super frustrating when everything else feels ready to go. Sometimes those specific muscles just take a bit longer to fully wake up and get back to their old selves after such a big surgery, even when the joint itself is good. Like David mentioned, foam rolling can sometimes help with that kind of stubborn tightness by working on the fascia and improving blood flow, as long as it's comfortable for you and doesn't aggravate anything. Have you experimented much with different angles or pressures with a foam roller on those specific quad areas? Sometimes a little shift in position can hit the spot. And just curious, since you've been through this before with the other knee, did you find anything particularly effective for those specific quad muscles the first time around, or is this a new kind of challenge with this recovery? Keep crushing it, mate! 💪`
