Complications may include injury to the tibia, femur, or knee ligaments. [2] It typically results from a hard blow to the front of the knee or falling on the knee. [1] The patella can also be fractured indirectly. For example, a sudden contraction of the quadriceps muscle in the knee can pull apart the patella. [1]
Common causes of PCL injuries are direct blows to the flexed knee, such as the knee hitting the dashboard in a car accident or falling hard on the knee, both instances displacing the tibia posterior to the femur. [1] Surgery to repair the posterior cruciate ligament is controversial due to its placement and technical difficulty. [2]
The cast or brace remains for at least 6 weeks followed by an unidentified time of rehabilitation of the knee. The usual risks of surgery are involved, including: infection, stiffness, death, suture reaction, failure of satisfactory healing, risks of anesthesia, phlebitis, pulmonary embolus, and persistent pain or weakness after the injury and ...
[17] [18] Carpal fractures are caused by falling on an outstretched hand the wrist is hyper-extended in ulnar deviation with a component of rotation. [18] Swelling of the Median nerve tissue leads to nerve entrapment ultimately resulting in restriction of movement, other symptoms include; pain, numbness and weakness. [ 1 ]
The knee anatomy provides insight into predicting why certain fracture patterns occur more often than others. The medial plateau is larger and significantly stronger than the lateral plateau. Also, there is a natural valgus or outward angulation alignment to the limb which coupled with the often valgus or outwardly angulating force on impact ...
Falling is the action of a person or animal losing stability and ending up in a lower position, often on the ground. It is the second-leading cause of accidental death worldwide and a major cause of personal injury , especially for the elderly . [ 4 ]
This complex is the major stabilizer of the medial knee. Injuries to the medial side of the knee are most commonly isolated to these ligaments. [1] [3] A thorough understanding of the anatomy and function of the medial knee structures, along with a detailed history and physical exam, are imperative to diagnosing and treating these injuries.
Patients with knee injuries suspected to involve the posterolateral corner should have their gait observed to look for a varus thrust gait, which is indicative of these types of injuries. As the foot makes contact with the ground, the compartments of the knee should remain tight and stabilize the joint through the impact and movements of walking.
