This is not a question they can be answered without a comprehensive physical, series of x-rays for the knee, and review of previous surgical interventions. I would recommend having an evaluation by an orthopedic surgeon to discuss your particular situation.

There are a few different sources of knee pain in adolescents. The best place to start is with a diagnosis. The knee should be evaluated by a sports medicine trained physician or orthopedic surgeon so that a proper H&P can be performed. If conservative treatments are not improving the pain then advanced imaging will likely be performed to further evaluate for an underlying cause.

The source of hip pain is hard to discuss without knowing the specific location of the pain. Most of the time hip pain can be treated non-operatively. Seeing a sports trained physian or orthopedic staff may prove beneficial to get you pointed in the right direction.

It is hard to tell without a formal history and physical. There are several muscles in the inner thigh (adductor compartment and medial hamstrings) that can develop tendinitis. A good initial approach would be to perform stretching of these areas as part of a knee strengthening program. If symptoms persist then a medical evaluation should be performed.

That depends on several factors. A few aspects of this are as follows: patient age, degree or percentage of tear, level of arthritis, patient activity level, other tears / injury, etc. Regardless, I would recommend having an ACL tear evaluated by an orthopaedic surgeon so the appropriate treatment can be started.
