The Ottawa knee rules are a set of rules used to help physicians determine whether an x-ray of the knee is needed. [1] They state that an X-ray is required only in patients who have an acute knee injury with one or more of the following: Age 55 years or older; Tenderness at head of fibula; Isolated tenderness of patella
If the tibia pulls forward or backward more than normal, the test is considered positive. Excessive displacement of the tibia anteriorly suggests that the anterior cruciate ligament is injured, whereas excessive posterior displacement of the tibia may indicate injury of the posterior cruciate ligament. [3]
The most common knee problems are: soft tissue inflammation, injury, or osteoarthritis. The mechanism of the knee injury can give a clue of the possible structures that can be injured. For example, applying valgus stress on the knee can cause medial collateral ligament rupture, meanwhile a varus force can cause lateral collateral ligament rupture.
In order to perform the test, the patient lies prone (face-down) on an examination table and flexes their knee to a ninety degree angle. The examiner then places his or her own knee across the posterior aspect of the patient's thigh. The tibia is then compressed onto the knee joint while being externally rotated. If this maneuver produces pain ...
The pivot-shift test [1] is one of the three major tests for assessing anterior cruciate injury or laxity, the other two being the anterior drawer and Lachman test. However, unlike the other two, it tests for instability, an important determinant as to how the knee will function. [ 1 ]
Hamman's sign (rarely, Hammond's sign [1] or Hammond's crunch [2]) is a medical sign consisting of a crunching, rasping sound, synchronous with the heartbeat, [3] heard over the precordium in spontaneous mediastinal emphysema. It is thought to result from the heart beating against air-filled tissues.
Step 2: Engaging your abs, bring your left knee up to your left elbow, extending it as far forward as possible. Return to the starting position. Return to the starting position.
The goals of rehabilitation following an ACL injury are to regain knee strength and motion. If an individual with an ACL injury undergoes surgery, the rehabilitation process will first focus on slowly increasing the range of motion of the joint, then on strengthening the surrounding muscles to protect the new ligament and stabilize the knee.
