Displacement is a frequent finding is these types of fractures, whereas direct traumatization induces a comminuted fracture, articular traumatization and, most likely, open fractures [3]. The patient does not benefit from any surgical intervention and is treated with a cylinder cast that is kept for 4 to six weeks, depending on the specific characteristics of the fracture. It is either a result of force directly exerted on the patella itself or occurs when quadriceps forcefully contract. Hence, fractures of the tibial plateau are often associated with injuries to the anterior cr… The joint itself alongside the part of the patella that lies above it are enclosed by the articular cartilage, which lubricates the structures in order to allow for smoother motion, minimal friction and damage to the bones. Surgical treatment For an osteochondral fracture that requires surgery, most likely it will be arthroscopic repair of the fracture … Acta Orthop Scand. Prolonged and intense pain 2.

The only difference is that with an osteochondral fracture, there may also be a bone fracture involved. A patella fracture is diagnosed with the help of an x-ray obtained at different angles, possibly an MRI and a thorough physical examination. An Osteochondral fracture is a tear of the cartilage which covers the end of a bone, within a joint.

If a major fall occurs for example, the joint is forced to absorb great pressure, which will result either in the rupture of the tendons or in a transverse patella fracture [2]. Experimental investigation of the tension band in fractures of the patella. Finally, open fractures are the severer type: the bone has torn out of the skin and adjacent structures have also sustained massive damage. Stable fractures are those whereby the two separated parts remain in place and correct alignment. The predominant symptom manifesting after a patella fracture is knee pain [7]; the patient's medical history will illustrate the way in which the traumatization was sustained: direct force, indirect force or a combination of those.

Operative treatment might also be necessary if patients do not respond well to conservative treatment. A potentially impaired joint can be aspirated, which will help diagnose hemarthrosis or a joint effusion; the latter leads to the aspiration of fluid containing fat globules. There are three possible causes of a patella fracture: Direct force exerted on the patella usually produces a comminuted fracture, as the regional anatomical structures are obliged to absorb the force.

These fragments can be of many sizes and depths and can stay attached (stable) to the area that was injured or become loose (unstable) inside the joint. tansverse, displaced fractures that become comminuted at a later stage. Patellar fractures are sustained in three different ways. An osteochondral injury is an injury to the smooth surface on the end of bones, called articular cartilage (chondro), and the bone (osteo) underneath it. Instability of the respective joint 4. Other areas affected include under the patella (knee cap) or along the talus bone in the ankle. Treatment is variable depending upon the size of the bone fragment, age of the patient and activity level of the patient. Typically, indirect fractures are a result of abnormal or excessive knee flexion. Gradual strengthening of the injured joint, along with sport or activity specific rehabilitation are the final phases to restore function. Since the superior and inferior medial geniculate arteries penetrate the knee joint, a patella fracture may severely compromise the knee blood supply, leading to an avascular necrosis [4]. Many people find that a Knee Brace or Support helps to provide warmth and alleviates their knee pain symptoms. An osteochondral fracture is caused by tearing of the articular cartilage.
