Abstract: An example implant device includes a base having a surface that mates with bone, and a plurality of tapered protrusions positioned on the base and extending from the surface of the base that mates with bone. A surface of the plurality of tapered protrusions includes a textured surface to increase area for bone growth. An example method for inserting the implant device into bone includes forcing the plurality of tapered protrusions of the implant device into the bone, and securing the implant device in place without cement due to the plurality of tapered protrusions cutting into the bone for fixation of the implant device.

Abstract: A system for enhancing sterility. The system includes a first surgical glove comprising an upper glove portion and a lower glove portion. A surgical garment comprising at least one surgical garment cuff, and a sealing device comprising a first adhesive. The first adhesive of the sealing device is configured to be affixed between an inside surface of the lower portion of the first surgical glove and an outside surface of the at least one surgical garment cuff so as to provide a fluid seal between the first surgical glove and the at least one surgical garment cuff of the surgical garment.

Abstract: A surgical retractor and configured to minimize tearing of the gloves without compromising the ability to grip tissue. The surgical retractor has a handle, a blade, and a plurality of retraction elements. The retraction elements may be fixed to the blade but arranged in a specific configuration that a minimizes tearing of the gloves without compromising the ability to grip tissue. The retraction elements may also be made deployable by having a deployed configuration in which the retraction elements are exposed, and a stowed configuration in which the retraction elements are hidden.

Abstract: Example methods and systems may be used intraoperatively to help surgeons perform accurate and replicable surgeries, such as knee arthroplasty surgeries. An example system combines real time measurement and tracking components with functionality to compile data collected by the hardware to register a bone of a patient, calculate an axis (e.g., mechanical axis) of the leg of the patient, assist a surgeon in placing cut guides, and verify a placement of an inserted prosthesis.

Abstract: Within examples, a surgical device with an embedded sensor system for performing hip replacements is described. This device mitigates fracturing of the mid metaphyseal/diaphyseal region of the femur, and ensures adequate press-fit of the component into the bone. The device relays information regarding forces experienced by the patient's bone to a separate data acquisition device and displays it on an interface. This information is used by the surgeon to determine the force present inside of the patient's bone during broaching, and can then be used to provide better care, and mitigate fractures due to overloading in the bone.

Abstract: A surgical leg positioner capable of bending the knee in varus or valgus while simultaneously distracting the tibia from the femur, the leg positioner having a thigh clamp module, a swing arm module connected to the thigh clamp module in a manner that offsets a joint axis laterally to the side of the knee of the patient so as not to damage the opposite compartment of the knee when bent in varus or valgus. The swing arm module also distracts the knee simultaneously when the knee is bent in varus or valgus. The swing arm module also permits flexion and extension of the knee at the knee's natural flexion-extension axis. The surgical leg positioner also utilizes a thigh brace that property aligns the leg on the surgical leg positioner.

Abstract: A reciprocating surgical saw blade includes a distal portion, a proximal portion, and a main body extending between the distal portion and the proximal portion. The main body includes an upper surface and a lower surface, and a first outer edge extending from the upper surface to the lower surface of the main body, and a second outer a second outer edge extending from the upper surface to the lower surface of the main body. A biocompatible polymer is provided along at least one of the upper surface, the lower surface, the first outer edge, or the second outer edge of the main body.

Abstract: A surgical device is presented that combines multiple components and functions, such as, joint distraction, soft tissue distraction, a separation force that exerts a uniform tension on the knee ligaments, pre-aligned cut guides, and posterior cut guards that protect the posterior knee joint from unintentional damage by the surgical saw. A method of performing a partial knee replacement is also presented.

Abstract: A surgical metal debris reduction system is provided for use in orthopedic surgical procedures having a metal block with one or more guide openings that accept bone cutting tools or bone drilling tools. One or more non-metallic bushings are included in the system that have outer dimensions such they can be removably inserted in the guide openings and have internal dimensions sized to accept bone cutting tools or bone drilling tools such that metal on metal contact is prevented during use of the tools, thus preventing or reducing generation and deposition of metal debris within the surgical field.
