We're moving closer to using 3D imaging to personalize operative vs nonoperative decisions for patients. 🏥🩹
Very grateful to collaborate with an amaing team including @aagatti.bsky.social, the JUPITER Study Group, Scott Delp, and Seth Sherman!

Key finding: Relative bone position matters most. 3D positions of the patella and tibia relative to the femur correlated strongly with 1-year nonoperative patient-reported outcomes.
Surprisingly, traditional 2D imaging measures and 3D bone shape were not correlated with outcomes!

Overlaid axial, sagittal, and coronal views of the mean control knee (score = 0.0) and the mean recurrent instability knee (score = 3.5). A higher score, associated with the recurrent instability cohort, reflects a combination of greater patellar tilt, height, and lateral displacement; greater external rotation of the tibia relative to the femur; more knee valgus; and more posterior offset of the tibia relative to the femur.
3D > 2D for patellar instability 🦵
Our new study in OJSM introduces 3D-PASS, a score that describes patellar instability severity using 3D anatomical data and is capable of predicting patient outcomes
Higher 3D-PASS <> worse predicted outcomes
