Three SPRI researchers took the stage at the 10th World Congress of Biomechanics in Vancouver last week, sharing new findings on ACL recovery and shoulder stability.
Colin R. Smith, PhD, Research Scientist, presented "Augmentation of Anterior Cruciate Ligament Reconstruction with Orthobiologic Injections Improves Muscle and Joint Function." Co-authored with Austin Carcia, Kristen Seballos, Armando Vidal MD, Jonathan Godin MD, Thomas Hackett MD, Peter J. Millett MD, Matthew T. Provencher MD, Johnny Huard PhD, and Scott Tashman PhD.
This randomized clinical trial found that PRP and BMAC injections at the time of ACL surgery led to greater quadriceps strength and improved limb loading during running as early as 6 months post-op, indicating accelerated functional recovery for patients.
Alex Brady, MS, Manager of Robotics & Engineering, presented "Stabilizing the Posteriorly Unstable Shoulder: Identifying Engagement Patterns and Thresholds of Bone Grafting in Bipolar Lesions." Co-authored with Ayham Jaber MD, Taylor K. Calibo MS, Tyler J. Uppstrom MD, Peter J. Millett MD, and Matthew T. Provencher MD.
This investigation provided the first robotic analysis of posterior dislocation across a range of clinically relevant lesion sizes and reconstructions, demonstrating that distal tibial allograft (DTA) and talus allograft (TA) reconstruction can improve stability in shoulders with significant bone loss.
Kristen Seballos, MS, Research Engineer, presented "In Vivo Dynamic Stereo X-Ray Analysis Shows Medial and Lateral Tibial Slope are Correlated with Graft Strain after Anterior Cruciate Ligament Reconstruction." Co-authored with Austin Carcia, Armando Vidal MD, Jonathan Godin MD, Thomas Hackett MD, Matthew T. Provencher MD, Peter J. Millett MD, Johnny Huard PhD, Scott Tashman PhD, and Colin R. Smith PhD.
Using dynamic stereo X-ray imaging, this study revealed how a patient's tibial anatomy directly influences the strain placed on an ACL graft, insight that may help guide surgical planning and reduce re-injury risk.
This kind of collaboration across engineers, surgeons and scientists is what keeps SPRI research moving from the lab to real clinical impact.
