Does live surgical broadcasting compromise patient safety?

This study of 94 patients undergoing arthroscopic anatomic glenoid reconstruction (AAGR) found that live broadcast surgeries were slightly longer (by 6 minutes), but had no increase in complications compared to non-broadcast procedures.

✅ No difference in intraoperative or perioperative complication rates
✅ One step closer to safer, global surgical education

Does posterior capsular release (PCR) alter knee kinematics during TKA?

This cadaveric study shows that PCR at the intercondylar fossa significantly improves knee extension angle by over 9°, without affecting rotational or translational knee kinematics in posterior-stabilized TKA.

Can AI help patients understand rotator cuff injuries—or is it too complex?

This study compared ChatGPT-4 with AAOS OrthoInfo content and found:

✅ Both sources delivered accurate information
⚠️ But ChatGPT required a significantly higher reading level (grade 14.7 vs. 11.9)

A novel patient-specific instrument (PSI) workflow for medial opening wedge high tibial osteotomy (MOWHTO) demonstrated high accuracy in alignment correction.

📐 Mean overall error: 0.2° ± 1.5°
🔍 First study to separately assess planning vs. surgical error
📊 KOOS scores improved significantly postoperatively

Findings highlight the need to address under-correction during surgery and planning over-correction.

A controlled cadaveric study demonstrates that femoral maltorsion alters both patellofemoral and tibiofemoral contact pressures.

· External rotation → ↑ medial PF + TF pressure
· Internal rotation → ↑ lateral pressure

Findings support the biomechanical rationale for derotational osteotomy in selected cases.

A new study published in evaluates the effectiveness of shortened versions of the KOOS in patients undergoing MPFL reconstruction for patellofemoral instability.

🔍 Key finding: A composite score using just the Sports/Recreation and Quality of Life subscales was more relevant and responsive than the full 42-item KOOS in this active population.

Every study has its limitations and in this reel, Renato Andrade from Clínicas Espregueira reflects on the constraints of using a finite element model based on a single patient.

👥 Population averages were used to simulate ligament structures, but real-world diversity remains a challenge.

The future? AI + computing power could enable multi-patient simulations and statistical analysis—bringing us closer to personalized, predictive modeling in orthopaedics.

🚨New episode!

Renato Andrade, Director of Research at Clínicas Espregueira FIFA Medical Centre of Excellence, shares key findings on internal brace placement during ACL repair using a sophisticated finite element knee model.

🔍 Insight: Strategic brace positioning—especially across the AMB and PLB footprints—can minimize stress and strain on the repaired ACL.
