Using WBCT to Explore Patient Specific Knee Kinematics

Most recently, CurveBeam AI and Vent Creativity explored the use of weight bearing CT (WBCT) to better understand each patient’s individual knee kinematics. While there has been a tremendous amount of work done to better understand how the knee joint works, most of these research techniques cannot feasibly carry over to routine clinic evaluation. WBCT may offer a realistic alternative for point of care imaging. While not first line of assessment, when surgical intervention is being considered, this imaging modality shows promise for providing a tremendous amount of information to improve surgical planning.

A quick, 35 second scan in both standing and flexed (40-45 degrees) position allows for comparison of bony landmarks. The comparison of scans depicts femoral rollback, external rotation, and delta changes in collateral ligament length. All these parameters can assist in improved implant selection, alignment, and constraint that would best serve each individual patient. This was discussed most recently at AAHKS in Dallas.

This early investigation serves as the foundation for expanding research in the near future
