WBAT means **Weight Bearing As Tolerated**. It is a common instruction that tells a person to put **as much weight through a leg as they can comfortably tolerate**. WBAT is frequently used after orthopedic injuries and surgeries, including hip procedures. It is typically paired with physical therapy guidance and an assistive device such as a walker or crutches.

Viscosupplementation hip is an injection-based treatment that places a gel-like fluid into the hip joint. The fluid is usually hyaluronic acid, a substance naturally found in joint fluid. It is most commonly discussed for osteoarthritis-related hip pain and stiffness. In the hip, it is typically performed with imaging guidance to help place the injection accurately.

Vastus medialis is one of the four muscles that make up the quadriceps on the front of the thigh. It helps straighten the knee and supports how the kneecap moves during motion. Clinicians commonly discuss it when evaluating anterior knee pain, kneecap tracking issues, and rehabilitation after knee injury or surgery. It is also referenced in sports medicine and physical therapy when analyzing lower-limb mechanics that can influence the hip, knee, and ankle.

Vastus lateralis is a large muscle on the outer (lateral) front of the thigh. It is one of the four quadriceps muscles that straighten the knee. Clinicians discuss it often in knee rehabilitation, sports medicine, and gait (walking) assessment. It is also a common site for intramuscular injections and muscle testing.

Vastus intermedius is one of the four muscles that make up the quadriceps in the front of the thigh. It sits deep under the rectus femoris muscle and attaches to the femur and the kneecap region through the quadriceps tendon. It is best known for helping straighten the knee and support everyday movements like walking, standing, and climbing stairs. Clinicians commonly reference it in orthopedic exams, sports medicine, physical therapy, and surgical rehabilitation.

VTE prophylaxis means steps taken to reduce the risk of blood clots forming in the veins. It is commonly used around orthopedic injuries and surgeries, especially hip and knee procedures. It can include medications, mechanical devices, and early movement strategies. The goal is prevention, not treatment of an existing clot.

Venous thromboembolism prophylaxis means steps used to help prevent blood clots in veins. These clots most often include deep vein thrombosis (DVT) and pulmonary embolism (PE). It is commonly used around orthopedic surgery, hospitalization, and periods of limited mobility. It may involve medications, mechanical devices, and early movement strategies.

The Vancouver classification is a system doctors use to describe fractures that happen around a hip replacement implant. It is most commonly used for periprosthetic femoral fractures, meaning fractures in the thigh bone (femur) near a hip stem. It helps organize what the fracture looks like, where it is located, and how stable the implant and surrounding bone are. Clinicians use it to guide communication, decision-making, and documentation in orthopedic care.

Vancouver C is a fracture classification term used in hip replacement care. It describes a femur (thigh bone) fracture that occurs well below a hip implant’s stem tip. It is part of the Vancouver classification system for periprosthetic femoral fractures. Clinicians use it to communicate fracture location and guide treatment planning.

Vancouver B3 is a label in a medical classification system for fractures that occur around a hip replacement stem. It describes a specific pattern: a break near the femoral implant with a loose stem and poor surrounding bone quality. Clinicians use it most often in the setting of periprosthetic femoral fractures after total hip arthroplasty (hip replacement). It helps standardize communication and guide planning for treatment and follow-up.
