Most ACL injuries can be diagnosed by examining the knee and comparing it to the other, non-injured knee. When a doctor suspects ACL injury in a person who reports a popping sound in the knee followed by swelling, pain, and instability of the knee joint, they can perform several tests to evaluate the damage to the knee.
The patient lies on their back with their knee flexed to between 45° and 60° and their foot externally rotated. The practitioner applies a valgus force while slowly extending the knee. A clunk will be felt around 30° of knee flexion if the subluxed or dislocated joint has reduced. This occurs as the iliotibial band changes from a knee flexor ...
The unhappy triad, also known as a blown knee among other names, is an injury to the anterior cruciate ligament, medial collateral ligament, and meniscus.Analysis during the 1990s indicated that this 'classic' O'Donoghue triad is actually an unusual clinical entity among athletes with knee injuries.
In most people, ligaments (which are the tissues that connect bones to each other) are naturally tight in such a way that the joints are restricted to 'normal' ranges of motion. This creates normal joint stability. If muscular control does not compensate for ligamentous laxity, joint instability may result.
A knee dislocation is an injury in which there is disruption of the knee joint between the tibia and the femur. [3] [4] Symptoms include pain and instability of the knee. [2] Complications may include injury to an artery, most commonly the popliteal artery behind the knee, or compartment syndrome. [3] [4] [7]
Iliotibial band syndrome (ITBS) is the second most common knee injury, and is caused by inflammation located on the lateral aspect of the knee due to friction between the iliotibial band and the lateral epicondyle of the femur. [2] Pain is felt most commonly on the lateral aspect of the knee and is most intensive at 30 degrees of knee flexion. [2]
A girl with genu recurvatum of her right leg due to polio. The following factors may be involved in causing this deformity: [citation needed] Inherent laxity of the knee ligaments; Weakness of biceps femoris muscle; Instability of the knee joint due to ligaments and joint capsule injuries; Inappropriate alignment of the tibia and femur
Symptoms may worsen if the knee is overly straightened or bent for too long a period. [2] Complications may include an inability to fully straighten the knee. [2] The underlying mechanism may involve bleeding, inflammation, or insufficient space for the fat pad. [2] This may occur as a result of trauma or surgery to the knee. [1]
