Not sure if it's the same thing, but I had an Orthroscopy after a Rugby Injury.
Might just be bad spelling on my part.
Care in the UK seems to be a bit behind what other's have written about here.
It was put in a Crepe bandage and I was told to come back in two weeks.
Only young at the time, so I did what I was told, by which point my knee had locked at a 90 degree angle.
Despite explaining this, the Doctor wanted to see me walk on it.
When he realised this wasn't possible, he called me in for Orthroscopy, which was explained to be simply an exploratory operation, with two small incisions made, so that a camera could be inserted.
I woke up during the night after surgery and got an immediate Morphine shot.
next I know, there's a Physiotherapist at my bed waking me up.
I must first explain that the Knee was in a light Crepe bandage, and not a caste.
"Right now" she says, "I'd like you to lift your leg off the bed as high as you can"
So I have a go, and really can't move it, as the pain is incredible.
"Well if you're not going to try" She say's gruffly "I'll help you".
At this point, she proceeds to lift my leg a foot off the bed.
"I'm going to count to three, and then let go. I wish you to control your legs descent"
She let go alright, my leg crashing onto the bed, resulting in me screaming out every profanity known to man.
"It really shouldn't hurt as much as that" she said, "Let me go and get your case notes"
So yeah, someone who'd just had an Orthroscopy shouldn't have had that experience, but what the surgeon had neglected to write in big bold letters on his report, was that they had spotted a mass of congealed blood inside the joint during the Orthroscopy, and he'd taken it upon himself to lift off my knee cap, and force the leg straight while I was under.
Anyway's the lesson I got out of the whole thing was mostly to do with Physiotherapy.
Regarding your knee's, go see someone like the head physio of a Skating or Football team. They'll give you a genuine prognosis.
