Power Knees is a joint support device that helps to reduce the effort and pain associated with regular activities. It looks like a traditional knee brace, with a long sleeve of fabric covering most of the mid-leg area and an opening at the front. The product's key innovation is found in its power storage and release feature. This is accomplished with the inclusion of a bending rod on the side of the sleeve that operates similarly to a spring.

Power Knees is first and foremost a knee brace. Its traditional design provides for consistent support at the joint. This reduces the likelihood of injuries occurring or recurring in the softer tissues, like tendons and ligaments. It also prevents the pain that can be caused from these parts moving freely, should they already be damaged.
This product is composed from materials that embrace the knee without being obvious and uncomfortable. It can be worn easily above or under clothing, and is breathable so that the skin underneath can still benefit from regular air exchange.
The most impressive and unique component of this product is the energy-storing item that rests against the side of the knee. It gives the brace a whole new dimension of functionality by allowing it to not just support the knee, but to provide active mechanical assistance when standing or otherwise straightening the leg.
Does It Really Work?
Yes, the Power Knees brace supports the knee as would a more traditional option by keeping pressure against the tissues. This reduces excess stretching of the ligaments, tendons and muscles within the joint. Its most interesting feature, the power suspension rods, works on the same physical principles as a spring. When the knee is bent the rod is contracted, storing the energy that has been used to make the original movement. Then, as the knee is straightened, the rod releases the energy and works alongside the joint to lift the body. The power boost reduces wear and tear on the knee while also enabling people to potentially accomplish tasks that they were previously too weak to do.
The video commercial for Power Knees starts by outlining some of the more common issues that arise from frequent knee usage. Pain is predictably a focal point, along with the restriction of activities that can result from degenerative joint conditions. The product is introduced as a solution and its unique design is discussed. An animated graphic shows the power suspension rods in action, as they are normally hidden beneath a pocket of fabric. Customer testimonials are provided and various benefits of using the device are highlighted, like being able to play on the floor with children and still stand again. It finishes by offering free shipping and telling viewers how to order.
- Non-locking Mechanism
The design of this device, while unique and helpful in many ways, may have an unintended consequence. Suspension power rods that store energy when bending do not lock into place when the knee is bent. This probably wasn't a practical option, given that users would need to disengage the lock before standing, but the fact remains that this arrangement will leave the spring "wanting" to straighten. Users may experience the energy that has been stored as a form of pressure, making it more difficult to keep the knees in a bent position. Similarly, the springs may impede the initial bending action because they will be naturally resistant to contraction. While the force is sure to be minimal, those with very weak knees may experience reduced or even eliminated benefits because of it.
