Can Hip Condition be service-connected as secondary to Knee Condition?

It can be claimed that way. Under 38 CFR § 3.310, a condition that is proximately due to — or aggravated by — an already service-connected disability can itself be service-connected. Whether VA grants it depends on the evidence in your file, and the decision is made solely by VA adjudicators.

Do I need a nexus letter for a secondary claim?

In most cases yes. The rater needs a medical opinion connecting the two conditions at the "at least as likely as not" (50% or greater) standard. That opinion has to come from a licensed clinician who reviews your records and signs it — a draft is a starting point for that provider, not a substitute for their judgment.

Hip Condition Secondary to Knee Condition

The medical link

Knee pain and instability alter the mechanics of the entire lower kinetic chain, placing abnormal loading forces on the ipsilateral hip joint.

What proves it

Orthopedic or radiology records documenting hip pathology; orthopedist nexus letter describing gait-related mechanical stress transferred to the hip.

The rule VA applies

38 CFR § 3.310 covers secondary service connection two ways: a condition caused by a service-connected disability, and one aggravated byit beyond its natural progression. Either route works, and a claim can argue both. The standard is “at least as likely as not” — a 50% probability, not proof beyond doubt.

You do not need to show hip condition began during service. That is what makes a secondary claim different, and it is the step most veterans do not realise is available to them.
