Total Joint
Unloading.

Levitation is the only knee brace capable of simultaneously unloading all three compartments of the knee during weight-bearing flexion 1– Budarick, A.R. et al. 2020.  J. Biomech. Eng. 142.
– Bishop, E.L. et al. 2020. Osteoarthritis and Cartilage 28
. Research has shown that Levitation can immediately reduce tibiofemoral and patellofemoral joint loads by up to 50%2– Budarick, A.R. et al. 2020.  J. Biomech. Eng. 142.
– McGibbon, C.A. et al. 2020. Submitted to the Journal of Biomechanical Engineering.
.

applying Treatment
Guidelines.

Treatment guidelines recommend reducing joint load through strategies such as weight loss3– Zhang et al. 2008. Osteo & Cartl 16
– Bannuru et al. 2019. Osteo & Cartl 27(11)
, which can be difficult to achieve for patients.  Levitation can reduce knee joint load to a level achieved by losing 45 lbs of body weight4– Budarick, A.R. et al. 2020.  J. Biomech. Eng. 142.
– McGibbon, C.A. et al. 2020. Submitted to the Journal of Biomechanical Engineering.
, reducing pain and allowing increased physical activity.

Clinically-Relevant
Improvements.

Research shows rapid improvements in pain, function, and quality of life with reduced dependence on pain medication. In fact, 95% of knee OA patients report reduced pain, 85% report improved function, 70% report increased physical activity, and 60% report reduced reliance on other treatments5Budarick et al. 2020. Submitted to Journal of Prosthetics and Orthotics.

PATIENT-CENTRED DESIGN EXEMPLIFIED.

DESIGNED FOR ALL KNEE OA PATIENTS

Levitation is designed to meet the needs of all knee OA patients, and uniquely those who exhibit multicompartmental or patellofemoral disease.

FOCUSED ON THE GREATEST IMPACT

The majority of symptomatic knee OA patients (50–94%) exhibit patterns of multi-compartment or patellofemoral OA 6– Hart et al. 2017 BJ Sport Med. 51(16)
– Duncan et al. 2006 Rheumatology 45
which cannot be effectively treated with traditional uni-compartment offloader knee braces. Only a small fraction of knee OA patients have arthritis restricted to a single tibiofemoral compartment 7– Hart et al. 2017. BJ Sport Med. 51(16)
– Duncan et al. 2006. Rheumatology 45
– Heekin et al. 2014. J. Knee Surgery 27
.

INDICATIONS FOR USE

Clinical Best Practice ACComplished.

Levitation reduces joint load equivalent to the loss of 45lb of bodyweight8Budarick, A.R., et al. 2020.  J. Biomech. Eng. 142 . Joint load reduction alleviates pain and improves function, and is widely considered a clinical best practice in the conservative treatment of knee OA. Ultimately, reducing joint loads increases the frequency and duration that patients are able to stay active9– McAlindon TE, et al. 2014. Osteoarthritis Cartilage. 22(3)
– Jevsevar DS 2013. 2nd edition. J Am Acad Orthop Surg. 21(9)

LEVITATION SAFELY UNLOADS ALL THREE KNEE COMPARTMENTS SIMULTANEOUSLY

Traditional OA braces are restricted to offloading one tibiofemoral compartment10– Budarick, A.R. et al. 2020.  J. Biomech. Eng. 142.

Is Levitation right for your patient?

Levitation reduces joint loads, reduces pain, and improves function, including during activities of daily living such as:

SQUATTING, CROUCHING & OTHER PHYSICAL ACTIVITY

Knee extension assist amplified.

Levitation functions by assisting the knee extension moment normally generated by the quadriceps when the knee is in flexion. By assisting the quadriceps, the large tensile forces normally transmitted to the patellofemoral and tibiofemoral joints via the quadriceps and patellar tendons respectively are reduced11– Budarick, A.R. et al. 2020.  J. Biomech. Eng. 142
– McGibbon, C.A. et al. 2020. Submitted to the Journal of Biomechanical Engineering
.

JOINT UNLOADING WHEN IT COUNTS

 

Unlike traditional knee OA braces, Levitation’s knee extension assist provides pain relief and joint unloading during knee flexion12– Budarick, A.R. et al. 2020. J. Biomech. Eng. 142
– Bishop, E.L. et al. 2020. Osteoarthritis and Cartilage 28
– McGibbon, C.A. et al. 2020. Submitted to the Journal of Biomechanical Engineering
. This is particularly useful for patients with patellofemoral defects or OA. Levitation directly assists quadriceps strength and mobility13– Bishop, E.L. et al. 2020. Osteoarthritis and Cartilage 28
– McGibbon, C.A. et al. 2020. Submitted to the Journal of Biomechanical Engineering
, allowing for neuromuscular retraining14– Cherian JJ. et al. 2015. J Arthroplasty 30(5).

UNPRECEDENTED ASSISTANCE

During physical testing of healthy individuals by the Canadian Military, Levitation significantly increased physical stamina and endurance as follows:

  • A 10% improvement in the maximum number of loaded squats
  • A 26% improvement in the maximum number of loaded leg presses
  • No change in heart rate when walking with versus without the TCU.
