The new Knee Cage by RCAI was designed to control Genu Recurvatum (hyperextension) of the knee. The RCAI Knee Cage permits knee flexion, aids in ambulation, and increases motion power of the quadriceps. The lightweight, thermoplastic construction of the brace conforms to the anatomy of the leg. The adjustable 3 point pressure strap behind the knee is padded for patient comfort. The new RCAI Knee Cage is indicated for hyperextension of the knee due to plantar flexion contracture, quadriceps weakness, and Hip Orthoses extension weakness
