reverse mcmurray test
Routine radiographs may be ordered to rule out other causes of symptoms or loose body, but they are not diagnostic for meniscal injury. Also, the appropriate clinical tests for the ACL, posterior cruciate ligament (PCL), medial, and posterolateral structures are performed.
Plain radiographs should be obtained to evaluate for a fracture or an osteochondral loose body. The suprapatellar pouch and medial and lateral gutters should be evaluated for presence of loose bodies or pathologic plicae masquerading as symptomatic meniscal tears. The McMurray test is performed in maximum flexion, progressing from maximum external rotation to internal rotation and then back to external rotation. Knees that have deficiency of the posterolateral structures may require lateral stress radiographs. Place the tested leg back in maximal hip and knee flexion.
Painful conditions of the knee, in Pain Management Vol 1., 2007. The anterior drawer test detects ACL injuries and is performed with the patient supine and the knee in 90 degrees of flexion. Un article de Wikipédia, l'encyclopédie libre.
Name. Likewise, external rotation of the leg can be applied to test the posterior portion of the medial meniscus.. This critical function in the range of 0 to 30 degrees is important for movements such as side-stepping and pivoting.
Validity of the McMurray's Test and Modified Versions of the Test: A Systematic Literature Review. IR of the tibia + Varus stress = lateral meniscus, ER of the tibia + Valgus stress = medial meniscus. The diagnostic value of this test was investigated by associating it with paradoxical McMurray Test. DOI https://doi.org/10.1016/C2009-1-59662-1. Required fields are marked *. A tear in the meniscus may cause a pedunculated tag of the meniscus which may become jammed between the joint surfaces. Philippe Gadet précise aussi que la fiabilité du test augmente lorsque celui-ci est associé au test de sensibilité par palpation des interlignes articulaires. What Types of Surgery Are Used to Treat Knee Injuries? Physiopedia is not a substitute for professional advice or expert medical services from a qualified healthcare provider.
The McMurray test is named after Thomas Porter McMurray, a British orthopedic surgeon from the late nineteenth and early twentieth century who was the first to describe this test.
When the mechanical block is dislodged and the knee extended, place the patient in a knee immobilizer, keep the patient non–weight-bearing with crutches, and refer the patient to an orthopedic surgeon for early arthroscopic examination and definitive treatment.
Other clinical signs include pain on forced flexion, obvious meniscal displacement during joint compression and flexion and extension, lack of full extension, and a positive McMurray test result.127,140 All ligament stability tests are performed and compared with the opposite knee joint. The basic premise of the McMurray test is that meniscus tears are trapped during certain knee movements, with resultant pain and clunking. Sorry, your blog cannot share posts by email. The medial and lateral compartments should be inspected for meniscal or chondral pathology. Saunders Elsevier. Common injury mechanisms are a sudden twist, change in direction (cut), or deep knee flexion.
It is possible to trap a meniscus fragment and cause the knee to lock completely.
Il est très souvent décrit dans les ouvrages de sémiologie français de façon partielle ce qui rend sa mise en œuvre encore plus délicate , pour les étudiants en médecine, en ostéopathie ou en kinésithérapie. Any pain or "clicks" serves as a positive diagnosis of a lateral tear of the meniscus. 5.13) to widen the cyst tract. Pinpointing the problem can be difficult. This test may produce a lateral palpable snapping sensation, representing an anterior subluxation of the posterior horn of the lateral meniscus with maximum internal rotation.
Absolute contraindications for meniscus repair, Complex, degenerative, or parrot beak tears, Relative contraindications for meniscus repair, Older physiologic age (i.e., >40–50 years), Unwilling to comply with physical therapy, Red–red zone: richly vascularized peripheral third of the meniscus with excellent healing potential, Red–white zone: middle third of the meniscus with favorable healing potential, White–white zone: avascular central third with poor tissue healing. Meniscus tears are frequently encountered in knees with ACL ruptures. The posterior drawer is the most sensitive test for evaluating function of the posterior cruciate ligament. Hegedus EJ, Cook C, Hasselblad V, Goode A, McCrory DC.
Posterior stress radiographs may be obtained in patients with PCL ruptures. Pain in a reproducible portion of the range of motion is described as part of McMurray's test.
Reliability of two clinical meniscal tests and magnetic resonance imaging. Since the passing of McMurray in 1949 there have been myriad descriptions, modifications and variations of the originally described test, which were seldom referenced to McMurray directly. McMurray Test – Orthopedic Examination of the Knee. Aggressive arthroscope or probe manipulation in tight medial or lateral compartments may risk iatrogenic chondral damage. Of interest, patients with physiologic joint laxity and increases in tibial rotation limits can commonly produce this lateral snapping sign in both knees under examination, which is not painful.
This is another of the most well known and most used special tests in orthopedics. The knee is brought to full extension while maintaining rotation. A thorough history includes assessment of the injury mechanism, initial and residual symptoms, and functional limitations.

There are several different reported methods of performing McMurrays Test, Reiders method may be the most accurate, Sign up to receive the latest Physiopedia news, The content on or accessible through Physiopedia is for informational purposes only.
With the patient in the prone position, the knee flexed 90°, and the femur stabilized with one hand, distraction is applied with the other hand by pulling upward on the ankle while rotating medially and laterally. Right knee shown. Brian R. Waterman, Brett D. Owens, in Operative Techniques: Knee Surgery (Second Edition), 2018.
Le test serait peu sensible . If comfort allows, gently and repeatedly perform the maneuvers of the McMurray test (see Chapter 115). A comprehensive knee examination is performed that includes assessment of knee motion, patellofemoral indexes, tibiofemoral pain and crepitus, muscle strength, ligament subluxation tests, and gait abnormalities. Outside-in pie crusting with gentle valgus stress may improve visualization and easier manipulation of the posterior horn through fractional lengthening of a tight medial collateral ligament. The procedure itself involves two steps, as follows: The second half of the test proceeds similarly: A test is considered positive when a click is felt over the meniscus as the knee is brought from full flexion (completely bent) to 90 degrees.  Most commonly, varus and valgus stress to the knee is added. The presence of tibiofemoral joint line pain on joint palpation is a primary indicator of a meniscus tear. A positive test is indicated by pain in association with a clunk, as the torn meniscus fragment is manipulated between the femur and tibia. Once the distraction portion of the test has been completed, compression is applied to alternately grind the medial and lateral meniscus between the tibia and femur, with gentle varus and valgus force applied, while internally and externally rotating and compressing the ankle downward (Apley grinding or compression test; Figure 6-38). Inadequate débridement of an unstable flap or complex meniscal tear may serve as nidus for continued pain or further tear propagation. Examination maneuvers include the Lachman, anterior drawer, lateral pivot shift, Apley compression, and, The presence of tibiofemoral joint line pain on joint palpation is a primary indicator of a meniscus tear. MRI of the knee will show a linear increased signal within the injured meniscus that extends to the articular surface (grade III signal change)23(Figure 26.8). 5.15). If a "thud" or "click" is felt along with pain, this constitutes a "positive McMurray test" for a tear in the posterior portion of the lateral meniscus.
The test is named after Thomas Porter McMurray.
With the patient supine the examiner holds the knee and palpates the joint line with one hand, thumb on one side and fingers on the other, whilst the other hand holds the sole of the foot and acts to support the limb and provide the required movement through range. Complex degenerative tears are often frayed and soft and may be débrided easily with the use of an arthroscopic shaver (Fig. An MRI will demonstrate most significant meniscal tears (Fig. The primary symptom from popliteomeniscal tears is lateral compartment pain with activities, especially turning and twisting with sports. 5.11).
The test is considered positive for a meniscus tear if the patient experiences medial or lateral joint line discomfort. The knee is internally and externally rotated at full flexion and then extended to elicit joint line pain or a palpable click.
102-14). A displaced bucket-handle tear may block full extension. Clinical Rehabilitation, 22(2), 143-61. The examiner’s thumbs should be placed on the femoral condyles, feeling the tibial offset at the level of the joint line (black arrowhead). The location of the connection between the meniscal tear and the cyst can often be identified with an arthroscopic probe, trocar, or Wissinger rod (Fig.
