I have had two knee scopes done on both of my knees and they still give me problem. They swell, pop, I can't climb stairs. Can I have another meniscus tear?

Unlikely. Many arthroscopic procedures to fix minor tears or clean up the knee are unnecessary and unhelpful. Your issue is much more likely to be osteoarthritic pain than a true symptomatic tear.
Possibly. Could be another meniscus tear. The difficulty with stairs suggests cartilage damage behind the kneecap (patella). I recommend that you see your orthopedist for evaluation.

What can be done if a knee MRI comes back negative but the patient is still having problems? Can a MRI miss a medial meniscus tear? Please explain

Yes. Yes it can miss about 8-10% of the meniscal lesions, as well chondral lesions are generally missed, rather frequently. I would advise you to see your orthopod who can examine you and then decide on the diagnosis. Good luck. Read more...

MRI. Mri can under estimate joint surface cartilage changes that cause pain. Referred pain from vascular or sciatic etiology may also be the culprit. Check with your orthopedic surgeon. Read more...

Could knees popping out of joint, post bilateral partial knee replacements for grade 4 patella chondromalacia in feb, cause a torn meniscus?

Depends. If your kneecap is popping in and out, this is a problem with the surgery and likely will not cause a meniscus tear. But if your knee itself is subluxating/popping out (rare), this certainly could cause a meniscus tear. Read more...
Refer to answer. Yes it can do popping, but does not causes torn meniscus. You patella may not be aligned. What ever contributed to you arthritis is causing spontaneous torn meniscus without trauma. See your pcp have the following tests done:cbc diff esr, RA ana, crp, uric acid TSH and hba1c. Stay away from all gmo food. Read more...
