Do these work?

Trying to build the muscle around my knee at the moment with the proviso that it has to be very low impact exercise. I've seen these used by physios etc so was wondering whether they'd be suitable for helping to build my knee up?

I'd cycle tbh, much more fun.

I think that's an 'Ogasmatron'

It's a gadget for blokes who can't get a girlfriend and are too embarrassed to buy a blow up doll.

No, in the name no. Don't send them your money but if you do wipe your backside with it first, I'll feel a little better.

I'm the master of knee problems, get a good remedial physiotherapist, work with him/her to get the whole leg muscles loosened up.
Free standing squats holding on to a post are the way to go, slowly but surely then you can start building up just by holding a 10K plate. Totally avoid leg extension machines.

From there progress on to squats with a bar but get some proper instruction if you're not sure on technique.

I spent a lot of time recovering from a bicycle crash damaging the muscles on my left knee only to crash my bike and land on the very same knee again.

Doing 10-20 miles a day on an exercise bike as well. I'm greedy and want it sorted!

Surgical tubing works great for resistance exercises on the cheap. Tie it in a loop and loop it around a chair leg, bedpost, Etc. As your knee gets stronger you can graduate to ankle weights.
