What does the Thessaly test test for?
What does the Thessaly test test for?
The Thessaly Test was first described in 2005 by Karachalios et al. as a novel clinical examination used to detect meniscal tears in the knee. When performed at 20° of knee flexion it is reported to have a high diagnostic accuracy rate for detecting both lateral and medial meniscal tears.
What does a positive Thessaly test mean?
meniscus tear
The test is considered positive for a meniscus tear if the patient experiences medial or lateral joint line discomfort or a sense of locking/ catching in the knee.
What is the most sensitive test for meniscal tear?
Based on MRI, Thessaly was the most sensitive for medial meniscus tears (56.2%), while McMurray and joint-line tenderness were more specific (89.1% and 88.0%, respectively).
What is ACL test?
The Anterior Drawer Test for anterior cruciate ligament (ACL) stability is a special test for your knee. It is designed to help you or your healthcare provider determine if you have sprained or torn your ACL. (A sprain is a tear to a ligament. The terms “ligament tear” and “sprain” are used interchangeably.)
How do you assess the meniscus?
The current standard used to assess for the presence of meniscal tears is to palpate along the joint line while applying a varus or valgus stress to the knee. It is important to feel for associated crepitation within the joint when performing this and also check if the patient has any pain with this maneuver.
Which two tests are used to test for a torn meniscus?
Imaging tests But X-rays can help rule out other problems with the knee that cause similar symptoms. MRI . This uses a strong magnetic field to produce detailed images of both hard and soft tissues within your knee. It’s the best imaging study to detect a torn meniscus.
What is MCL and LCL?
The MCL is the ligament located on the inside of your knee joint. It links your thighbone (femur) and shinbone (tibia). The LCL is the ligament located on the outside of your knee linking the thighbone and calf bone (fibula).
Who made the Lachman test?
The test is named after orthopaedic surgeon John Lachman, late Chairman of the Department of Orthopaedic Surgery and Sports Medicine at Temple University School of Medicine in Philadelphia, Pennsylvania. The original description was submitted by one of his colleagues, JS Torg.
What does the McMurray test assess?
The McMurray test for torn meniscus can provide the clinician with useful information as to the whether a torn medial or lateral meniscus is responsible for the patient’s knee pain.
What does the McMurray test indicate?
The McMurray test, also known as the McMurray circumduction test is used to evaluate individuals for tears in the meniscus of the knee. A tear in the meniscus may cause a pedunculated tag of the meniscus which may become jammed between the joint surfaces.
What is ACL or PCL?
The posterior cruciate ligament (PCL) is a ligament within the knee. Ligaments are tough bands of tissue that connect bones. The PCL — similar to the anterior cruciate ligament (ACL) — connects the thigh bone (femur) to your shin bone (tibia). Although it is larger and stronger than the ACL, the PCL can be torn.
What is the ACL test?
What are the 2 most popular tests for the ACL?
Index test(s) The anterior Lachman test, anterior drawer test and the pivot shift test, which are summarised in Table 1, are the most commonly known physical tests used to assess the integrity of the ACL (Benjaminse 2006; Leblanc 2015; Malanga 2003; Scholten 2003; Solomon 2001).
What does McMurray positive mean?
The test is considered positive for a torn meniscus if the examiner appreciates a palpable or auditory click while rotating and extending the knee.
What is the Thessaly test used for?
Thessaly test is used to detect lateral or medial meniscal tears of the knee joint. It is based on dynamic reproduction of load transmission in the knee joint under normal or trauma condition. How do you do the Thessaly test? The patient first stands barefoot on the healthy leg, supported by the examiner, who holds the patient’s outstretched hands.
What does a positive Thessaly test result mean?
The Thessaly test demonstrated a +LR of 1.37 (95% CI: 1.10, 1.70) and positive predictive value of 87% (95% CI: 83%, 90%). The +LR indicates that a positive Thessaly test result is 1.37 times more likely to be expected in a patient with a meniscal tear compared to a patient without a meniscal tear.
How accurate is the Thessaly test for the diagnosis of meniscal tears?
The Thessaly test, a newly described dynamic clinical examination, has been shown to have a very high diagnostic accuracy for detecting meniscal tears. This study evaluates the accuracy of the Thessaly test in patients with combined ACL and meniscus injuries.
What is the sensitivity and specificity of the Thessaly test?
Sensitivity: .90; Specificity: .98; +LR: 39.3; -LR: .09 (“The Thessaly test for detection of meniscal tears: validation of a new physical examination technique for primary care medicine”).
