What is a Thessaly Test?

The Thessaly test is a physical examination procedure used to determine whether there is a meniscus injury in the knee joint. It is a clinical test that healthcare providers may carry out, including orthopedic surgeons, physical therapists, and sports medicine doctors.

Before performing more intrusive diagnostic procedures like an MRI, the Thessaly test is frequently used as an early screening technique. It may be done in a clinic or office environment and is a simple, non-invasive test.

The test involves the patient standing on one leg and slowly rotating their body while bending the knee joint to about 20 to 30 degrees. The test is then repeated with the other leg. 

A meniscal injury may be indicated if the patient feels pain or a clicking sound while undergoing the exam. It is crucial to remember that a positive Thessaly test does not always show meniscus injury and further testing is often required to diagnose.

The Thessaly test has both diagnostic and therapeutic applications for individuals who have meniscal injuries. The test helps identify specific movements that exacerbate the patient's symptoms, which can subsequently be avoided or changed to lessen pain and enhance function.

It is crucial to remember that while the Thessaly test help diagnoses meniscal injuries, it is not a conclusive diagnostic technique. Further imaging tests or arthroscopic inspection may be required to confirm the diagnosis and assess the injury's severity.

How does this Thessaly Test Knee work?

The Thessaly Test for the knee is a clinical examination used to assess the integrity and stability of the knee joint. Here are the steps involved in performing the Thessaly Test:

  1. Patient Positioning: The patient stands barefoot with feet shoulder-width apart and hands resting on a nearby support for balance.
  2. Initial Knee Flexion: The examiner instructs the patient to flex their knee to approximately 20-30 degrees.
  3. Test Execution: The examiner stands behind the patient and holds their hands for stability. The patient is asked to rotate their body towards the tested knee, keeping the foot planted on the ground.
  4. Medial Rotation Test: With the patient in this position, the examiner applies a rotational force to the knee by placing one hand on the patient's distal tibia and the other on their proximal tibia. The examiner then rotates the knee internally (medial rotation) while keeping the foot fixed on the ground.
  5. Lateral Rotation Test: After completing the medial rotation test, the examiner performs the same rotational force in the opposite direction, externally rotating (lateral rotation) the knee while keeping the foot planted.
  6. Observation of Symptoms: During both rotational movements, the examiner pays close attention to any pain, discomfort, or clicking sounds reported by the patient. The presence of pain or joint line discomfort may indicate meniscus pathology.
  7. Repeat Testing: The Thessaly Test is repeated for each knee if both knees are being assessed.
  8. Interpretation: Based on the presence or absence of pain or joint line discomfort reported by the patient during the test, the examiner can assess the integrity of the knee joint and potential meniscal involvement.

It's important to note that the Thessaly Test is a clinical examination and should be performed by trained healthcare professionals experienced in orthopedic assessments. It is typically used in conjunction with other diagnostic tools, such as imaging studies, to aid in accurately diagnosing and managing knee injuries and conditions.


The Thessaly Test is primarily a clinical assessment procedure healthcare professionals use to evaluate the stability and integrity of the meniscus in the knee joint. Thus, it doesn’t have a defined scoring system, however, physicians can use a subjective grading method based on the patient's reactions and observable symptoms. If a scoring system is used, it is often employed by the researcher or physician conducting the examination.

For instance, a simple scoring method would give each of the test's symptoms a numerical value. A scale (e.g., 0-10) can be used to assess the patient's stated level of pain or discomfort; a greater score denotes severe pain. Similar to binary values (e.g., 0 for absent, 1 for the present), the presence or absence of other symptoms like clicking or locking can be noted.

The total severity or likelihood of meniscal damage can be determined by adding or comparing these scores. However, it’s crucial to remember that the Thessaly Test may be scored using a different method depending on the healthcare practitioner, research, or organization administering it.

When to use these Thessaly assessments?

Physicians use a clinical examination technique called the Thessaly assessment to test the stability and integrity of the meniscus in the knee joint. When there is a possibility of meniscal injury, this information is especially helpful. Thessaly assessment may be applicable in the following circumstances:

Suspected Meniscal Tears

The Thessaly Assessment may help confirm or rule out meniscal tears in patients who report knee pain, swelling, or mechanical symptoms like clicking or locking. It helps identify the precise motions that cause discomfort or reenact symptoms related to meniscal injury.

Pre-operative Evaluation

The Thessaly Test can give important information regarding the state of the meniscus before surgical surgery. It aids orthopedic surgeons in determining the severity of the meniscal injury and the best surgical strategy, such as repair partial/total meniscectomy.

Rehabilitation Monitoring

The Thessaly Test can be used to track the development of rehabilitation following meniscal damage or surgical intervention. It allows medical professionals to analyze the integrity of the repaired meniscus, evaluate the success of rehabilitation, and make informed decisions regarding the patient's recovery timetable.

Differential Diagnosis

Meniscal injuries can be distinguished from other knee disorders that may present with identical symptoms using the Thessaly Test. Reproducing specific symptoms associated with meniscal pathology aids in distinguishing between meniscal tears, ligamentous injuries, osteoarthritis, or patellofemoral pain syndrome.

Research and Clinical Studies

The Thessaly assessment is widely used in research and clinical studies on knee joint injury. It provides standardized criteria for evaluating meniscal stability and can contribute to understanding meniscal injuries, treatment outcomes, and long-term prognosis.
