It would be really nice if the medical questionnaire had a space for previously cleared with either "no change in condition" or "historical information only" that would negate the need for a new physical.
The OP's situation would be perfect for this. He has a stable, historical, orthopedic issue. Once he is cleared to dive, until and unless the condition changes, there should be no need for yearly clearance.
Other situations, such as diabetes, hypertension, heart disease, etc. should get a periodic assessment for dive fitness whether or not anyone requires it. This is for the diver's safety.
