A co-worker of mine had his done years ago, he was back to work (on his feet all day) probably a week or two later. My uncle had his done and I recall seeing him walking very soon after. If it makes a difference, my co-worker was probably 18 when he had it done. Being young probably helps with the recovery time.
As for the X-Ray…sometimes the doc can tell based on the way he manipulates the joint what it probably is, but does the X-ray to rule out a fracture. Mostly since they’re considerably cheaper than an MRI.
You can start with PT, if it’s anything like my labrum tear (cartilage between the ball and socket in your shoulder) , the idea is to build up the muscle in that area so the cartilage doesn’t have to support it AND make sure you’re not compensating in some way that’s going to end up doing more damage. For example, if it’s making you walk with a limp, you’re going to end up with your other knee hurting, or your ankle or back bothering you. A physical therapist will help you build up the muscle in the surrounding area so you can still walk properly.
If you have your mind set on surgery, you’re going to need to see an orthopedist, so you might as well make an appointment. They’re probably going to want an MRI, but if it’s a knee guy (and you may want to ask your primary for a referral to a knee guy), he/she may very well be able to diagnose something this routine without an expensive test.
Do keep in mind, though, orthos tend to be cutters. Even though you may want surgery, that is the direction you’re going to be pushed towards, they’re not, in general, going to try to talk you out of it.
When I saw my ortho for my shoulder, he gave me a shot of cortisone (already knowing I had a tear based on the MRI) and said ‘if this doesn’t help, we’ll have to go in and fix you’, and said it like it was as routine as going to check the mail.
I do regret putting the surgery off for so long. While my shoulder is still tight a year later (but that’s another story), the pain from the actual tear was gone within a few weeks/months. It was well worth it.
Also, again, if it’s similar to a torn labrum (labRUM, not the other thing, I don’t have one of those), when I asked my doc what would happen if I ignored it, he said it could end up arthritic. Not something I wanted in my early 30’s.
TL;DR, go see an orthopedic surgeon.
