A rehabilitation device that has a foot support with a width that substantially covers the arch of a patient's foot. The foot support has a closure system that allows the support to snugly receive and support the foot. The device has at least one strap detachably attached to the foot support, the strap comprising a fastener to allow a loop to be formed in the length of the strap. The device is operated by pulling the foot toward the knee to increase range of motion after knee injury.

A device which restricts movement of the knee during lunge and squatting exercises prevents weight imbalance which may result in undue strain and knee injury. The device has a foot engagement member which is either stepped upon by the user and held in place by the user's weight, or the foot engagement member conforms to the side of the user's foot and is held in place by a strap or other means. Attached to the foot engagement is a vertical member which extends upwardly from the foot engagement member. A shin engagement member attached to the vertical member. The shin engagement member is generally positioned in a position along the lower leg of the user, below the knee and laterally adjacent to the user's tibia. As the user does a lunge, squat, or similar exercise, the shin engagement member prevents the user's knees from forward movement which extends forward of the user's feet. The device also has structure which prevents inward collapse of the knees during the exercise.

A device for exercising leg muscles, ligaments, and tendons attendant to movement of a human knee following knee replacement surgery or during rehabilitation following knee injury is provided. The user lies supine on a flat surface and braces the back of his or her upper thigh against the device's leg support bar, so that the user's upper thigh is approximately perpendicular to the user's upper torso. The patient maintains this position and exercises the knee by extending and flexing his or her lower leg. Some embodiments include an elastic band that attaches to the device in a position that limits the degree of leg flexion to within a desired range. Some embodiments include an ankle strap attached to a cord, which may be used to build quadriceps strength through application of resistance, and/or for applying downward pulling force to the lower leg during passive range-of-motion exercising.

Footwear, such as a sports shoe, that has a cleated scaffold that attaches to an underside of a sole of the shoe body of footwear because of an attachment mechanism. The mechanism has cooperative components arranged to engage each other when in alignment to allow the cleated scaffold and shoe body to move in unison and in the absence of a critical pivoting force. When a critical pivoting force arises, such as when the cleats remain fixed in position in a manner that resists their movement in unison with the shoe body, the scaffold dissociates from the shoe body in order to reduce/prevent knee injury.

Wakeboarding causes a large number of knee injuries, especially to the ACL. These injuries occur from large tensile, compressive and rotational forces on the knees. Rotational and compressive forces cause meniscus tears. Rotation and tensional forces lead to ACL tears.
