Less often, this type of fracture can affect the metatarsal bone of the foot. An osteochondral fracture is caused by tearing of the articular cartilage. J Orthop Trauma. The forces sustained by the patella when the quadriceps muscles contact are able to strain the former at such an extent that an indirect fracture can occur. The precise technique is decided depending on the particular characteristics of each fracture and greatly depends on whether it is an open fracture, if arthrotomy has been sustained and if ligaments will have to be repaired as well. Depending on their morphology, primary patella fractures are divided in transverse, vertical, osteochondral, sleeve and marginal [1], with the fracture located at the top, lower part or center of the patella. It is important … Abstract Patella fractures comprise 1% of all fractures. We present the case of a 10-year-old, overweight, female patient. There is soft tissue swelling (white arrow) and a joint effusion (blue arrow). Fractures of the tibial plateau are considered quite serious as this upper surface of the bone contains structures which are critical to the knees functioning. Fracture of the patella. Chondral and osteochondral injuries are relatively common in the weightbearing joints of the lower extremity. Suitable protection like kneepads are required, if one participated in a sport likely to cause knee injuries. Includes: possible causes, signs and symptoms, standard treatment options and means of care and support. Open fractures are operated as an emergency condition. Open reduction internal fixation of displaced transverse patella fractures with figure-eight wiring through parallel cannulated compression screws. Osteochondral Fractures are also sometimes known as articular cartilage injuries. It is a structure located in the front part of the joint of the knee, at the point where the femoral bone and the tibia are joined together. Ann Chir Gynaecol Fenn Suppl. In general, the patella is an anatomical structure that is susceptible to injuries, due to the fact that it is located subcutaneously and is therefore not as protected from extreme forces as other structures are.

The lateral and medial retinacula are responsible for a person's ability to flex the knee, an ability that is preserved if both structures are unharmed after an injury. Tetanus shots are also mandatory if a wound is open. Lidocaine can be administered intra-articularly, in order to reduce the pain and allow for a more extensive examination of the patient's ability to extend the knee against gravity. Displaced fractures usually present with abnormal appearance of the knee and the dislocated pieces may as well be palpable. Instr Course Lect. tansverse, displaced fractures that become comminuted at a later stage. Depending on the extent of the fracture, the activity level of the patient, and symptoms that are present, the options for treatment are either conservative or surgical.

These fractures are most commonly seen in the knee and ankle joints, as these joints take a lot of strain and bear a lot of weight, which can make them vulnerable to damage. This may result in the traumatization not only of the patella, but of the cartilage and femoral condyles as well. Unfortunately, these fractures are often missed on initial radiographs. the patient has any signs of an intra-articular effusion or me-chanical symptoms.10,11 In the setting of a repair-able chondral/osteochondral fragment, anatomic repair is advised using the most ap-propriate fixation principles, Fractures where the bone segments are out of place need to be operated on, in order to reconstruct the patella or remove some of the pieces that cannot be placed in their right position. Your knee might be extremely swollen. Your joint might pop or stick in one position if a loose fragment gets caught between bones during movement.

Severe locking or catching syndromeOsteochondral Lesion Picture 1 – Tibial Osteochondral Fracture The causes of osteochondral injuries are not yet completely understood, but some theories are lack of blood supply to the affected area, heredity, direct compressive trauma or repetitive strain. 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]. Moreover, a patellar fracture can be comminuted when it’s broken in several pieces, transverse or vertical when it’s broken in two parts, and osteochondral when it involves the cartilage that is found at the bottom of the kneecap. Symptoms After the initial pain and discomfort of a strain or sprain subsides, individuals usually resume or even increase their activity level. The degree of injury ranges from a small crack to a piece of the bone breaking off inside the joint. Disclaimer: The information provided on this site is intended for your general knowledge only and is not a substitute for professional medical advice or treatment for specific medical conditions. the second one is an indirect mechanism, whereby the patella is injured when the thigh muscles contract very violently; the quadriceps (thigh muscles) are connected to the kneecap, so their abrupt and violent contraction strains the patella to such an extent, that a fracture can occur. 2008 Mar; 8(1):55-8.

Depending on the severity of the fracture, there are a number of treatment options ranging from fairly conservative treatments to surgery. In most cases, the osteochondral fracture is located in the medial facet of the patella. All patients Magnetic resonance imaging plays an important role in its early diagnosis, and early treatment can prevent damage to the articular cartilage as well as decrease the dislocation rate. 10-20% of the patients who undergo open reduction internal fixation also experience displacement of the patella segments following surgery, which is believed to be the case when the separated parts are not fixed together properly by a surgeon [6]. 1994; 43:97–108. Respectively, the lateral patellar retinaculum is formed by the last part of the vastus lateralis and is also attached to the patella. Methods.

Nummi J. Fracture of the patella: a clinical study of 707 patellar fractures. X-rays obtained from a lateral, anteroposterior and axial perspective are widely used to provide critical information about the skeletal structures underneath tissue. A patella fracture is diagnosed with the help of an x-ray obtained at different angles, possibly an MRI and a thorough physical examination. 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. [radiopaedia.org], From the time of the original fixation she had experienced mild persistent anterior knee pain, with a reduced range of motion and grinding. 3. The patient initially wears a cast for 1-1.5 month and then, if recovery is proceeding, discontinues the cast use and starts to wear a removable brace. Fortis AP, Milis Z, Kostopoulos V, et al. A widely used surgical technique generally involves the conversion of tensile force into a compressive one, with the use of a tension band, thereby helping the patella to regain continuity faster [9] [10].

The skin around your joint might be swollen and tender. The third mechanism involves a combination of the two aforementioned ways. 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]. A patient can stop using a removable brace when they are able to flex their knee joint over 90 degrees and raise their leg freely against gravity. Should the patella sustain tensile-type force, such as the type sustained when the quadriceps contact violently in hyperflexion, the most common fracture acquired is a nondisplaced fracture. In a displaced fracture, alignment is impaired and surgical intervention is necessary before the bone starts to heal. Your gift will assist patients and families and support research. [smw.ch], Conclusion To us it is vital to obtain CT scan of the patient's knee if there is an ipsilateral femoral fracture with an ipsilateral knee effusion and a punction which reveals hematoma even in the absence of a fracture line seen in AP and lateral projections UW Health's Sports Medicine doctors treat a wide range of common athletic injuries.

A patient also needs to be evaluated for the presence of hemarthrosis and damage to the extensor mechanism, namely the medial and lateral retinacula. The patella bone is otherwise known as the "kneecap" bone. Radiographic depiction assesses the direction of the fracture, its type, possible comminution and other important features.
