A Cement restrictor is a small device placed inside a long-bone canal to block (“restrict”) the flow of bone cement. It is most commonly used during cemented joint replacement surgery, including some knee replacement and revision procedures. By creating a temporary barrier, it helps surgeons control where cement goes and how it pressurizes the bone. It is a tool used in the operating room, not a medication or an implant you would typically feel afterward.

Cement pressurization is a surgical technique used when bone cement is applied and intentionally pushed into prepared bone. It is most commonly used during joint replacement, including total knee arthroplasty (knee replacement). The goal is to improve how well cement interlocks with bone to help hold an implant in place. It is a technique within surgery, not a stand-alone treatment.

Cement mantle is the thin layer of bone cement between an orthopedic implant and the patient’s bone. It is most commonly discussed in joint replacement surgery, including total knee replacement. The cement mantle helps attach the implant to bone and distribute forces across the joint. It is not a “treatment” on its own, but a structural part of how some implants are fixed.

TXA is short for tranexamic acid, a medication that helps reduce bleeding. It is commonly used around surgeries and injuries where blood loss is a concern. In orthopedics, TXA is frequently used during knee replacement and other knee procedures. It is not a pain medicine, and it does not “heal” cartilage or ligaments.

Tranexamic acid is a medication that helps reduce bleeding. It works by slowing the breakdown of blood clots once they form. It is commonly used around surgery, including many knee and joint procedures. It is also used in some non-orthopedic bleeding situations, depending on the clinical setting.

Tourniquet use refers to applying controlled pressure around a limb to temporarily reduce or stop blood flow past a certain point. In orthopedics, it is most commonly used during surgery on the arm or leg to create a clearer, drier operative field. It can also be used in emergency bleeding control, which is a separate setting with different goals and risks. In knee-related care, it is typically applied on the thigh during procedures involving the knee joint.

Patient-matched cutting guides are custom surgical templates made to fit one person’s knee anatomy. They help surgeons position and guide bone cuts during knee replacement surgery. They are most commonly used in total knee arthroplasty (total knee replacement) and sometimes in partial knee replacement. They are created from preoperative imaging, then manufactured to match the contours of the femur and tibia.

A Cutting block is a surgical guide that helps a surgeon make planned bone cuts accurately. It is most commonly used during knee replacement surgery and some other reconstructive procedures. The device is positioned on bone so cutting instruments can follow a controlled path. Its goal is precision and repeatability rather than treatment by itself.

An Extramedullary alignment guide is a surgical instrument used to help align bone cuts during knee surgery. It works from outside the bone, using external landmarks rather than a rod placed inside the bone canal. It is most commonly used during total knee arthroplasty (knee replacement), especially on the tibia (shinbone). Its goal is to help the surgeon position implants in a more planned, consistent way.

An Intramedullary alignment rod is a surgical instrument placed inside the hollow center (“canal”) of a bone to help guide alignment. It is commonly used during knee surgery to position cutting guides and implants accurately. In the knee, it is most often associated with aligning the femur (thigh bone) during total knee replacement. It is typically a temporary tool used during the operation, not an implant meant to stay in the body.
