Hip muscles may be smaller in unilateral OA.

Here, some "low quality evidence that specific hip muscles are smaller in unilateral hip OA".
Does this translate to osteoarthritis leads to muscular atrophy and thus weakness, or does this translate to muscle atrophy and weakness leads to OA ? Chicken or the egg ?
Sure, there is the whole trauma thought process, but that is not the discussion today.

Regardless, some possible implications here for targeted interventions in hip OA. This is why so many with arthritic joints improve with pointed, well thought out and target strengthening.
