I was nervous planning it—would anyone show up or engage? But it turned into one of the most inspiring days I’ve been a part of. Packed sessions, amazing speakers, and real momentum for future partnerships across clinical and academic teams at HFH + MSU. ⚡️

💡 Key takeaway: ACL rehab should focus on body composition, not BMI, to optimize long-term outcomes.
📊 Lean mass = strength & function
⚠️ Fat mass = pain & worse performance

🦵 ACLR restores stability, but timing & rehab matter! ⏳⚕️ Early surgery (<3 months) and reducing arthrofibrosis may lower PTOA risk in young athletes.
🏹 Further research is needed to optimize long-term joint health.

Can you improve this??
✅While wireless and traditional ultrasound showed high reliability for cartilage thickness,
❌low reliability for echo-intensity persisted, even after pixel normalization.😕
⚡This points to room for improvement in ultrasound tech!

I just joined Bluesky and love the idea of these starter packs! I research early OA after ACL injuries and would love to be added to the MSK and Ortho Research pack. Thanks for organizing this!
