Q-angle measurement is a way to estimate the line of pull of the quadriceps muscle relative to the patella (kneecap). It is commonly used during knee exams to describe alignment that may influence patellar tracking. Clinicians may use it in orthopedics, sports medicine, and physical therapy when evaluating anterior knee pain. It is a clinical measurement that supports (but does not replace) a full diagnosis.

The J-sign is a physical exam finding seen when the kneecap (patella) moves in a “J-shaped” path as the knee straightens. It is most commonly used to evaluate patellar tracking and patellofemoral instability. Clinicians look for it during an office knee exam, often in people with anterior knee pain or a history of the kneecap “slipping.”

The Patellar apprehension test is a physical exam maneuver used to assess suspected kneecap (patella) instability. It looks for “apprehension,” a protective reaction when the patella feels like it may slip out of place. Clinicians commonly use it in orthopedic, sports medicine, and physical therapy knee evaluations. It is a bedside test that complements the history, full knee exam, and imaging when needed.

Clarke test is a hands-on knee exam maneuver used to assess pain around the kneecap. It is sometimes called a patellar grind test in clinical conversation. It is most commonly used in orthopedic, sports medicine, and physical therapy evaluations. It aims to provoke symptoms related to the patellofemoral joint (the kneecap and thighbone).

Patellar grind test is a hands-on knee exam maneuver used to assess pain at the kneecap joint. It is commonly performed in orthopedics, sports medicine, and physical therapy evaluations. The test aims to reproduce symptoms that may come from the patellofemoral joint (where the patella meets the femur). It is one piece of the overall knee assessment, not a stand-alone diagnosis.

Joint line palpation is a hands-on exam technique used to feel along the knee’s joint line. It helps clinicians identify where pain, swelling, or tenderness is coming from around the knee. It is commonly used in orthopedics, sports medicine, and physical therapy knee evaluations. It is a clinical assessment step, not a treatment.

The Apley grind test is a hands-on knee exam maneuver used to assess the meniscus. It is commonly performed in sports medicine, orthopedics, and physical therapy settings. The test applies gentle compression and rotation to look for pain or mechanical symptoms. It is one piece of a broader knee evaluation, not a stand-alone diagnosis.

The Thessaly test is a physical exam maneuver used to help assess the knee meniscus. It is commonly performed in clinics for knee pain after twisting injuries or sports. It involves standing on one leg with a slight knee bend and gently rotating the body. Clinicians use it as part of a broader knee examination, not as a stand-alone diagnosis.

McMurray test is a hands-on knee exam maneuver used to check for a possible meniscus tear. It is commonly performed during an orthopedic or sports medicine knee evaluation. The test looks for pain, catching, or a “click” as the knee is moved in a specific way. It is one piece of the overall clinical exam, not a stand-alone diagnosis.

The Posterolateral drawer test is a hands-on knee exam maneuver used to assess abnormal backward and outward movement of the tibia (shinbone) relative to the femur (thighbone). It is most commonly used when a clinician suspects injury to the posterolateral corner (PLC) of the knee and related stabilizing structures. It is performed in the clinic as part of a broader knee stability examination. It helps guide whether further testing or imaging may be needed.
