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. ⚡️

Excited to share our work on the small but mighty microRNA-126-3p in @naturecomms.bsky.social! We found this microRNA is elevated in four knee osteoarthritis cohorts and show in an animal model that it reduces the severity of knee osteoarthritis - at least in part via angiogenesis. rdcu.be/ebycj

📢 New research challenges BMI as a predictor of ACL recovery. Instead, body composition—lean vs. fat mass—better correlates with strength & function. 🔬 DXA showed: ✅ More lean mass → Stronger quads, better mobility ❌ More fat mass → Worse knee pain & performance 📉 BMI? No significant correlation.

📢 Interesting study in Orthopaedic Journal of Sports Medicine 🦵🔬: Among 16,935 pediatric ACL reconstructions, 1.6% developed PTOA within 5 years. Key risk factors: ⚠️ Motion restoration surgery (OR = 5.0) 👶 Age ≤12 (OR = 4.8) ⏳ Delayed ACLR (OR = 1.8) ⚖️ Obesity (OR = 1.4) ⚡ Male sex (OR = 1.3)

🚨 NIH’s indirect cost policy might not stick. 🧪 Turns out, there’s already a law preventing NIH from making these changes without congressional approval. Hopefully there’s a good chance this IDC change won’t move forward as planned. Something to watch! 👀

🔬 NIH’s new policy to cap indirect costs at 15% is a major blow to research institutions. 🧪 💰 Less funding for operations = fewer resources for science. ⚠️ Small institutions may struggle to sustain research. 🏛️ This could impact the future of NIH-funded projects. 🔗 grants.nih.gov/grants/guide...

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! 📷Examples across scanners & normalization

🏆 Wireless ultrasound is a game-changer! 🔬 Our new study in Osteoarthritis Imaging confirms that Clarius wireless ultrasound probes accurately measure knee cartilage thickness—comparable to traditional systems. 📊 A big step toward more accessible ultrasound technology! 🔗: doi.org/10.1016/j.os...

Adding this post to the science🧪 feed! 🚨 Ultrasound + Bone Shape = New Research! 🚨 We developed a novel B-Score 🧮 using an ultrasound-based statistical shape model 🩻 to measure femoral bone shape post-ACLR 🦵 ✅ Accessible ✅ Accurate (92%!) ✅ Early detection potential 📖 LINK👉shorturl.at/lto3A

Development of SSM and B-Score Process. Overview of the process to develop the statistical shape model (SSM) and B-score. Bone Line Registration: Three ultrasound images from one knee are acquired and their cartilage segmented; the bone line is then extracted from the cartilage and normalized. Statistical Shape Modeling: PCA is performed to obtain shape feature scores for each bone line. Bone Shape Scoring: Bone line shape feature scores are projected onto the ACLR vector, resulting in the B-Score.

🎉 Huge congrats to Arjun Parmar for publishing his first research paper! 🎉 Arjun took lead on developing this ultrasound-based B-Score to quantify femoral bone shape post-ACLR 🦵. A major step toward accessible knee health monitoring 🚀! 👏 Well done, Arjun! #ProudAdvisor

📈Bone Shape Comparison 🦵 🔍 Ultrasound-based B-Score captures subtle but significant differences in femoral trochlear bone shape: 🟦 Healthy = Deeper trochlear groove 🟥 ACLR = Flatter groove ✨ B-Score thresholds identify these changes with 99% shape variance explained ✅.

📊 B-Score Accuracy 🎯 We validated our ultrasound-based B-Score to classify femoral bone shape post-ACLR 🦵 ✅ 92% Accuracy 🏆 ✅ High Sensitivity (97%) 📈 ✅ Clear separation of ACLR (🔴) vs. Healthy (🔵). B-Score = a promising tool for detecting post-ACLR bone changes early!
