Dr Masataka Enomoto joins CAM to explore the frontier of early identification in canine osteoarthritis. From automated pain evaluation and force-plate research to activity-monitor insights, microbiome patterns and his landmark data on how young dogs really are when radiographic OA appears, this episode dives deep into what the next decade of OA detection could look like.

Listeners will gain clarity on why early OA is still routinely missed, what technologies show genuine promise, and how objective tools could reshape the caregiver–vet partnership in spotting pain far earlier.

Bio

Dr Masataka Enomoto is a Research Assistant Professor of Orthopedic Surgery at North Carolina State University. He earned his veterinary degree from Azabu University in Japan and now focuses on cartilage regeneration, pain management, early OA detection and comparative orthopaedic research.

His publications cover NGF-blocking monoclonal antibodies, force-plate gait analysis, activity monitors, microbiome associations, and the prevalence of radiographic OA in young dogs.

Key takehomes

1. Automated pain evaluation is progressing but not yet ready for widespread clinical use; it holds strong promise for future early OA detection.

2. Activity monitors can reveal early reductions in movement long before lameness appears, but they remain underused in practice.

3. Microbiome research is emerging and may help explain multi-joint OA patterns; however, clinical application is still distant.

4. Comparative force-plate work has provided objective insight into the performance of grapiprant versus bedinvetmab in early OA pain management.

5. Dr Enomoto’s prevalence research confirms radiographic OA is common even in young dogs, underscoring how urgently early identification must become routine.
