precise reproducible tension and fixation for soft tissue repair and reconstructions

Tension should be measured not estimated

SURGERY REQUIRES PRECISION AND SURGEONS CAN EFFECTIVELY MEASURE AND RECORD EVERY STEP EXCEPT ONE... TENSION

Over 90% of surgeons1 rely on their sense of “feel” when tensioning soft tissue during anterior cruciate ligament reconstruction procedures. The use of “feel” has been shown to differ surgeon to surgeon, patient to patient2 and is a factor influencing why >40%3 of patients do not return to their prior level of activity and 10%4 of patients experience a re-rupture after anterior cruciate ligament reconstruction.

TENSIONING IS NEEDED TO IMPROVE PATIENT OUTCOMES

Measured tensioning during reconstruction surgery has been shown to lower re-rupture rates5, improve patient outcomes6 and lower the incidence of osteo arthritis7.

New augmentation techniques can dramatically lower failure rates8 and improve patient return to prior level of activity9

Surgeon’s use of augmentation is low due to the risk of incorrect tensioning of the augmentation, which could impact healing of the new tendon and lead to higher re-rupture rates and complex revision surgery.

Tesa kNEE SYSTEM:
PRECISE TENSION & fIXATION

  • Proprietary fixation devices

  • Bluetooth enabled digital tensioning tool

  • ENTERPRISE SOFTWARE PLATFORM

SURGERY REQUIRES PRECISION AND SURGEONS CAN EFFECTIVELY MEASURE AND RECORD EVERY STEP EXCEPT ONE... TENSION... UNTIL NOW!

TESA’s enabling technology will generate real time data aligning pre and intra operative decision making to real world patient outcomes creating a new standard of care for soft tissue repair and reconstruction.
