Partial knee replacement is a surgery that replaces only the damaged part of the knee joint. It is most often used when arthritis affects one compartment of the knee more than the others. It is also called unicompartmental knee arthroplasty in clinical settings. The goal is to restore smoother joint motion while preserving as much healthy bone and tissue as possible.

TKR stands for total knee replacement. It is a surgery that replaces damaged knee joint surfaces with artificial components (a knee prosthesis). TKR is most commonly used for advanced knee arthritis and severe knee joint damage. It is discussed in orthopedic clinics, sports medicine settings, and physical therapy plans for end-stage knee pain and stiffness.

Total knee replacement is a surgical procedure that replaces damaged knee joint surfaces with artificial components. It is most commonly used for advanced knee arthritis and other conditions that severely affect daily function. The goal is to reduce pain and improve stability and movement when other options have not provided enough relief. It is performed by orthopedic surgeons in hospital or surgical-center settings.

TKA means **total knee arthroplasty**, also called **total knee replacement**. It is a surgery that replaces worn or damaged knee joint surfaces with artificial components. TKA is commonly used to treat advanced knee arthritis and severe knee joint damage. It is performed in orthopedic surgery settings and followed by structured rehabilitation.

Total knee arthroplasty is a surgical joint replacement for an arthritic or damaged knee. It replaces worn joint surfaces with artificial components to restore smoother motion. It is commonly used for advanced knee osteoarthritis and other severe joint conditions. It is performed by orthopedic surgeons in hospital or surgical center settings.

Anteromedialization TTO is a surgical realignment procedure involving the tibial tubercle, the bony bump where the patellar tendon attaches on the front of the shinbone. It is a type of tibial tubercle osteotomy (TTO), meaning a controlled bone cut and repositioning. “Anteromedialization” describes moving that attachment point forward (anterior) and toward the inside (medial). It is commonly used in patellofemoral problems such as kneecap maltracking, recurrent instability, and cartilage overload–related pain.

Medialization TTO is a surgical technique that shifts the tibial tubercle slightly toward the inside (medial side) of the knee. It is commonly used to improve how the kneecap (patella) tracks in the groove at the end of the thigh bone (trochlea of the femur). It is most often discussed in care for patellofemoral pain, maltracking, or recurrent kneecap instability. It may also be combined with other knee procedures when multiple problems contribute to symptoms.

Joint line obliquity describes how “tilted” a joint surface is compared with a reference line, often the floor or the body’s mechanical axis. In the knee, it usually refers to the slope of the femur–tibia contact line in the coronal (front) view. Clinicians use it as a measurement concept in imaging, alignment assessment, and surgical planning. It commonly comes up in knee osteoarthritis, limb deformity evaluation, osteotomy planning, and total knee replacement discussions.

MAD is an orthopedic measurement that describes knee and leg alignment. MAD stands for **mechanical axis deviation**, meaning how far the body’s weight-bearing line shifts from the center of the knee. It is most commonly measured on a standing, full-length leg X-ray. Clinicians use MAD to evaluate bow-legged (varus) or knock-kneed (valgus) alignment and to help plan or monitor treatment.

Mechanical axis deviation is a measurement of how straight (or not straight) a leg is in standing. It describes where the body’s weight-bearing line passes through the knee. Clinicians use it to understand knee alignment in conditions like bowlegs (varus) or knock-knees (valgus). It is commonly used in orthopedic imaging, surgical planning, and follow-up after alignment procedures.
