KNEE FLEXION muscle Biceps Femoris Origin N.S Long head: ______, Fibula, head and Sciatic nerve tuberosity lateral condyle of L5-S3 Short head: lateral lip tibia of linea aspera

Semi-membranosis ______, ischial tuberosity

Semi-tendinosis ______, ischial tuberosity

Tibia, ______ Extends the hip posteromedial L5-S3 Internally rotates portion of medial the hip condyle Flexes the knee Internally rotates the flexed knee

KNEE FLEXION ROM MEASUREMENT Start Position.The patient is ______.The hip is in the anatomical position and the knee is in extension (0 °) (Fig.2-3).A towel is placed under the distal thigh.

Parallel to the longitudinal axis of the ______, pointing toward the lateral malleolus.

From the start position of knee extension, the hip and knee are ______.

The heel is moved toward the buttock to the limit of knee ______.

The ______ is stabilized, and the lower leg is moved in an anterior direction beyond 0 ° of extension.

Accessory muscles: gastrocnemius, popliteus, ______, and sartorius.

The ______ may limit the range of knee flexion in the prone position.

The patient may attempt to ______ back during the test to place the rectus femoris muscle on stretch and increase the contribution from this muscle to produce knee extension.

Resistance Location is applied on the ______ surface of the distal end of the leg.

Ensure the patient does not ______ the knee in full extension (close-packed position).

The patient is ______-lying on the non-test side.

The therapist ______ the weight of the lower extremity.

The therapist ______ the thigh.

The patellar articular surface is flat or slightly convex _______________ and superoinferiorly

The patellar articular surface articulates with the anterior surface of the ___________

The motion of the patella relative to the femur in knee flexion and extension is referred to as patellar ____________

The gliding of the patella on the femur during knee flexion and extension is essential for normal motion at the ___________

In full knee flexion, the patella slides ____________ and lies in the intercondylar notch

In full knee extension, the patella slides ____________ and the lower portion of the patellar surface articulates with the anterior surface of the femur

The ______ Test is commonly used in orthopedic examinations to test for anterior cruciate ligament (ACL) integrity. The test is performed with the patient in a relaxed supine position and the knee to be tested should be flexed to about 15 degrees. One of the examiners hands holds and stabilizes the distal femur of the leg to be tested. The examiners other hand firmly grasps the proximal tibia of the same leg. From the starting position, the examiner pulls anteriorly on the proximal tibia. This test is considered positive if there is a soft end feel to the translation of the tibia. A soft end feel / endpoint is indicative of secondary structures stopping the continued anterior translation of the tibia. Excessive anterior translation may also be noted. A hard/firm end feel will be felt when the ACL is intact and abruptly halts continued anterior translation. The ______ Test is quite accurate but should not be used as the only criterion for ruling in or out ACL integrity. What is the name of this test?

The ______ Test is commonly used in orthopedic examinations to test for damage/tears to the meniscus. The test is named after Thomas Porter ______. What is the name of this test?

The Lachman Test is performed with the patient in a relaxed ______ position.

The knee to be tested in the Lachman Test should be flexed to about ______ degrees.

The examiner in the Lachman Test pulls anteriorly on the ______ tibia.

A soft end feel in the Lachman Test is indicative of secondary structures stopping the continued anterior translation of the ______.
