A knee is worked up in the same order every time. The visit opens with when the symptoms started, how they have changed, and what you want to get back to. The examination comes next, before any imaging, and the imaging then sharpens what the exam found.
X-rays show the space left between the bones, which stands in for the cartilage you cannot see on them. A full-length standing x-ray shows the alignment of the whole leg and where your weight actually passes through the knee, which a knee-only view cannot. An MRI shows the soft tissues that x-rays miss.
The aim in every case is to keep your own tissue working. If the real problem is the alignment of the leg overloading one compartment of the knee, realigning the limb takes the stress off that compartment and can settle the symptoms. If the damage is a meniscus tear, anything that can be repaired is worth repairing, because the tissue that stays protects the surfaces underneath it. Where exercise and time have stopped helping, regenerative medicine covers non-surgical options, and knee surgery tells you what an operation consists of.
None of that makes replacement a bad idea. Replacement is recommended when it is likely to deliver a lasting benefit, not because a scan looks bad. It is simply not the automatic first option here: the starting assumption is joint preservation, and those calls sit with a surgeon trained to make them.

Atlanta patients come to this at every point. Some have had a painful knee for a month, some show up with an MRI and a diagnosis they just want reviewed, and some have been living around a knee injury for years.
