Extremely reliable, safe and lightweight. The EASI Knee is an ideal choice for older or less active amputees who need to reach a locked position quickly and easily. The patient will benefit from the confidence achieved in having a knee they can trust and find easy to use. The positive semi-automatic knee lock with easy action lock actuator can be operated by those struggling with dexterity issues. To unlock the knee, the patient does not need to load the toe; this means the patient remains balanced, and can even unlock the knee from a seated position.
