Thus, if a person has greater core stability, they have a greater level of control over the position and movement of this area of their body. The body's core is frequently involved in aiding other movements of the body, such as running; thus it is known that improving core stability also improves a person's ability to perform these other movements.
If the anterior movement of the affected knee is greater than the unaffected knee, then the anterior drawer test is positive. The Lachman test is more sensitive than the anterior drawer test. For the Lachman test, the person lies down in supine position with the knee flexed at 20 degrees and the heel touching the bed. The tibia is then pulled ...
The McMurray test is named after Thomas Porter McMurray, [2] a British orthopedic surgeon from the late nineteenth and early twentieth century who was the first to describe this test. The description of the test has since been altered from the original by various authors. [3] Most commonly, varus and valgus stress to the knee is added. These ...
As always, compare the test in the opposite knee. [4] [5] [12] Dial Test (anteromedial rotation test)- This test should be executed with the patient lying both supine and prone. When the patient is supine, the knees must be flexed 30° off the table. The thigh is then stabilized and the foot externally rotated.
The straight leg raise is a test that can be performed during a physical examination, with the leg being lifted actively by the patient or passively by the clinician. If the straight leg raise is done actively by the patient, it is a test of functional leg strength, particularly the rectus femoris element of the quadriceps (checking both hip flexion and knee extension strength simultaneously).
The knee is a modified hinge joint, a type of synovial joint, which is composed of three functional compartments: the patellofemoral articulation, consisting of the patella, or "kneecap", and the patellar groove on the front of the femur through which it slides; and the medial and lateral tibiofemoral articulations linking the femur, or thigh bone, with the tibia, the main bone of the lower ...

The requirements are limb symmetry, there good sided leg strength is symmetrical to the ACLR side, of 90% in the quadriceps strength test, 90% in each of the four single-legged hop tests, 90% on the Knee Outcomes Survey-Activities of Daily Living scale (KOS-ADLs), and in general rating of self-perceived knee function.
