Abstract: A prosthetic knee can include a variable-torque magnetorheological (MR) actuator assembly or braking system, a frame and an electronics assembly or system that also serves as a mount for the knee actuator and facilitates in monitoring and controlling the operation of the knee actuator. The prosthetic knee system advantageously provides resistive forces to substantially simulate the position and motion of a natural knee joint during ambulation and/or other locomotory activities performed by the amputee. The prosthetic knee can be enclosed in a waterproof compartment. An outer cover can be configured to fit around the waterproof cover of the prosthetic knee.

Abstract: An orthopedic walker or walking boot has a body formed from at least one polymeric material. The body defines an upper receiving section, a lower receiving section, and a footbed. The upper receiving section includes first and second portions divided by a median plane of the orthopedic walker, and are arranged to individually articulate about or from the median plane to expand or retract a variable distance between the first and second portions of the upper receiving section along one of anterior or posterior sides of the body. The body may consist of the upper receiving section, the lower receiving section, and the footbed as a continuous structure formed unitarily from the expanded thermoplastic.

The prosthetic knee can be have a series of internal blades for providing resistive forces. A locking ratchet can be used to lock knee position. A dynamic seal with a protective shim can be disposed in the knee actuator. A coil with a non-circular cross-section can be used.

Abstract: A dynamic tension system connects to an orthopedic device having a frame and a hinge connected to the frame. The dynamic tension system includes a cable, an adjustment mechanism connected to the cable and arranged to incrementally wind or release the cable, and a tension control device connected to the adjustment mechanism and arranged to limit the adjustment mechanism from winding of the cable past a predetermined tension level.

Abstract: An orthopedic device has first and second elongate struts each having a strap coupling member, and a flexible strap securing to the first and second struts by the strap coupling members. The orthopedic device includes various embodiments of hinge assemblies including flexion and extension stops and locks for maintaining the hinge assembly in a fixed configuration. The orthopedic device has various embodiments of strap assemblies for securing components to cuff assemblies.

Abstract: A prosthetic adapter including a lower connector, an upper connector rotatably coupled to the lower connector, and a locking mechanism for preventing the upper connector from rotating relative to the lower connector. The locking mechanism is arranged to generally automatically retain a locked position when the lower connector is rotated to an original, predetermined alignment. An activation member is connected to and arranged for operating the locking mechanism.

Abstract: A negative pressure wound therapy (NPWT) orthopedic device includes a base shell and a dorsal shell contoured to generally correspond to an opening of the base shell. The dorsal shell includes a proximal section and a distal section. The proximal section at least in part defines a receiving space. A NPWT system includes a pump mechanism secured in the receiving space and a wound covering situated inside of the base shell and arranged to form a sealed volume over a wound area of a user. At least one conduit forms a fluid connection between the wound covering and the pump mechanism. The pump mechanism is arranged to apply a negative pressure to the wound area through the at least one conduit.
