Unclear: If you are unable to flex your knee beyond 45 degrees, there may be a mechanical block. You should see a sports medicine specialist or an orthopedist to get hands on exam and likely an mri.

Yes, time for MRI: Patellar dislocations may have concurrent acl/mcl tears, but this is relatively uncommon. Inability to bend the knee could be due to a fracture, significant swelling or a mechanical block like a loose body (bone, cartilage piece). It's time to have a further evaluation by your orthopedic specialist, and most likely, an MRI will be ordered.

Time 4 medical eval.: At this time you need to seek the advice of an orthopaedic surgeon who you trust. You need to be examined and may need studies such as xrays or an MRI to assess your injury.

Yes it's possible: You should see a sports medicine specialist whose expertise includes knee reconstruction; acl/mcl and patella dislocation are more commonly independent, but sometimes do occur from the same injury; your md will perform a thorough exam which often can diagnose the injury(ies), get x-rays to rule out fracture, likely order mri, recommend + oversee treatment; you might benefit from surgery. Good luc.
