Maintain optimal post-op knee
“A persistent flexion contracture can be a greater impairment than limited knee flexion with poor long term outcomes and may cause abnormal stresses on both knees.” The Journal of Arthroplasty 29 (2014) 85-89
The Zero Knee was created by a total knee arthroplasty surgeon. He spent years using pillows, blankets, and other devices to maintain post-op extension. None of these methods adequately prevented internal rotation of the foot, nor reliably allowed for full extension of the knee. He worked with Bone Foam to design the Zero Knee.
- Elevates the heel to create adequate free space posterior to the knee, to allow for full knee extension
- Keeps the toes pointed toward the ceiling in a neutral position
- Prevents external rotation of the foot, thus eliminating the associated flexion at the knee
