A target
An operation should correct a specific mechanism, not simply an abnormal image.
Function
Walking, sleep, work, stairs, sport and independence often matter more than an imaging grade.
When to wait
If symptoms are acceptable, diagnosis is uncertain or a realistic non-surgical option remains, waiting can be an active medical decision.
When to move forward
Continuing the same ineffective treatment indefinitely is not necessarily more conservative once the diagnosis and expected benefit are clear.
