The PTO is one of the most effective braces for reducing patellofemoral pain resulting from maltracking or patellar instability. This versatile brace features the patented Cawley Tension Hinge, which is proven to normalize patellar tracking at the most critical point of knee motion: full extension. By dynamically adjusting the amount of compression applied from the lateral pressure plate on the buttress, the Cawley Tension Hinge aids in pain relief by forming a soft tissue wall that controls patellar subluxation.
