An intraarticular fracture is a bone fracture in which the break crosses into the surface of a joint. This always results in damage to the cartilage . [ 1 ] Compared to extraarticular fractures , intraarticular have a higher risk for developing long-term complications, such as posttraumatic osteoarthritis .
For example, a sudden contraction of the quadriceps muscle in the knee can pull apart the patella. [1] Diagnosis is based on symptoms and confirmed with X-rays. [3] In children an MRI may be required. [3] Treatment may be with or without surgery, depending on the type of fracture. [2] Undisplaced fracture can usually be treated by casting. [2]
The Müller AO Classification of fractures is a system for classifying bone fractures initially published in 1987 [1] by the AO Foundation as a method of categorizing injuries according to therognosis of the patient's anatomical and functional outcome. "AO" is an initialism for the German "Arbeitsgemeinschaft für Osteosynthesefragen", the ...

Radiography to identify possible fractures after a knee injury. A bone fracture may be diagnosed based on the history given and the physical examination performed. Radiographic imaging often is performed to confirm the diagnosis. Under certain circumstances, radiographic examination of the nearby joints is indicated in order to exclude ...
The kneecap is prone to injury because of its particularly exposed location, and fractures of the patella commonly occur as a consequence of direct trauma onto the knee. These fractures usually cause swelling and pain in the region, bleeding into the joint (hemarthrosis), and an inability to extend the knee. Patella fractures are usually ...
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.
Patellofemoral pain syndrome (PFPS; not to be confused with jumper's knee) is knee pain as a result of problems between the kneecap and the femur. [4] The pain is generally in the front of the knee and comes on gradually. [2] [4] Pain may worsen with sitting down with a bent knee for long periods of time, excessive use, or climbing and ...
