A specialist is a good idea, although Xrays of the patella might not be ideal to ddx patella luxation, as this is a disorder that comes from movement, and probably would not show up on an Xray as by definition Xrays look at static joints. The Xray would be more definitive for hip problems, be they from Hip Dysplasia and or FHO, or other disorders at the hip joint.

I have not tried one-handed to assess LP, I usually use my two hands, ditto for hip assessment.

In terms of arthritis, unfortunately dogs just like humans are at risk for this, most especially with bio-mechanical problems at any joint. There are supplements you could add to her food, the research is equivocal on the efficacy of many of these supplements. Also there has been very little research that shows contra-indications to these supplements. Glucosamine, Chondrotin et al. I do supplement my large breed dogs with a joint supplement..

One of the key things is to keep her weight lean. Limit jumping onto hard surfaces. Focus on great walks, swimming if she likes to swim, no chasing balls on slippery surfaces, as the sudden stops and or turns on slippery surfaces are hard on the joints. Interactive puzzle toys are good, games like find Moms, or get my slippers ie training to fetch and retrieve are also good.
