Abstract
Patellar bracing is a component of treatment of patellofemoral joint (PFJ) problems. A new vacuumic brace was designed by the researchers that act based on an external vacuuming suction. Ten patients were undertaken for the CT scan study at both 0 degrees and 30 degrees knee flexion immediately pre- and post-bracing. Also they examined clinically pre, post and 1 week after using the brace. Measurements of patellofemoral joint space width (PFJSW) and patellofemoral joint area (PFJA) showed that the application of the vacuumic brace is able to create a significant patellofemoral joint distraction at both knee angles. A significant reduction in visual analog scale (VAS) and increase in kujala patellofemoral score (KPS) was found in subjects after using the brace for 1 week. In conclusion, the results conveyed that application of the vacuumic brace is able to create a joint distraction and useful changes in VAS and KPS parameters.
