THA stands for total hip arthroplasty, also called total hip replacement. It is a surgery that replaces damaged parts of the hip joint with artificial components. It is commonly used for severe hip arthritis and certain hip injuries. It is performed by orthopedic surgeons in hospitals and surgical centers.

The Thomas test is a hands-on physical exam maneuver used to assess hip flexor tightness and hip flexion contracture. It is commonly performed on an exam table with the patient lying on their back. Clinicians use it in orthopedics, sports medicine, and physical therapy to help explain hip and sometimes low back symptoms. It is a clinical screening tool, not an imaging study and not a treatment.

A Therapeutic hip injection is a clinician-delivered injection intended to reduce hip-related pain and inflammation. It typically places medication into the hip joint or nearby soft tissues using anatomic landmarks or imaging guidance. It is commonly used in orthopedics, sports medicine, and physical medicine for hip arthritis and certain tendon or bursa problems. It may also help clarify whether pain is coming from the hip joint versus another source.

TFL most commonly refers to the **tensor fasciae latae**, a small muscle on the outer front part of the hip. It connects into the **fascia lata** (a thick sheet of connective tissue) and helps tension the **iliotibial band (IT band)**. TFL is often discussed in orthopedics, sports medicine, and physical therapy when evaluating **lateral hip pain** and movement mechanics. In some surgical contexts, “TFL” can also describe a **TFL flap** used for soft-tissue reconstruction near the hip and thigh.

Tensor fasciae latae is a small muscle on the outer front part of the hip. It helps tense the fascia lata, a strong sheet of connective tissue along the thigh. It connects into the iliotibial band, which continues down the outside of the leg. Clinicians commonly discuss it when evaluating lateral hip or outer-thigh pain and movement mechanics.

Tendinopathy is an umbrella term for painful or symptomatic tendon problems. It is commonly used in orthopedics, sports medicine, and physical therapy. It describes tendon pain with impaired function, often related to loading and overuse. It can involve the hip region (for example, gluteal or hamstring tendons) and many other joints.

Tendinitis is a term used for pain and irritation involving a tendon. A tendon is the strong tissue that connects muscle to bone. Tendinitis is commonly discussed in orthopedics, sports medicine, and physical therapy. It is often used when activity-related pain is suspected to come from a tendon around a joint, including the hip.

Tendonitis is irritation and pain involving a tendon, the strong tissue that connects muscle to bone. It is commonly used as a general label for painful overuse problems around joints. In hip care, it often refers to painful tendons around the pelvis and upper thigh. Clinicians may also use related terms like tendinopathy when changes are more chronic than inflammatory.

Taper corrosion is wear-and-corrosion that can occur where two metal implant parts lock together in a cone-shaped junction (a “taper”). It is most commonly discussed in total hip replacement, at the head–neck connection of the implant. It can release tiny metal debris and metal ions into nearby tissues. Clinicians consider it when evaluating certain types of hip pain or implant-related inflammation after arthroplasty.

T2 mapping hip is a specialized MRI technique that creates a quantitative map of cartilage health in the hip joint. It measures a property called the “T2 relaxation time,” which relates to cartilage water content and collagen structure. It is commonly used in orthopedic and sports medicine imaging to evaluate early cartilage changes. It is most often performed as part of a broader hip MRI exam, not as a stand-alone test.
