Osteochondral fractures of the patella are commonly associated with acute patellar dislocations. Open fractures are operated as an emergency condition. Clin Orthop Relat Res. Chondromalacia Patellae - Learn common causes, signs, symptoms, expert views, diagnosis and treatment at Consumer Health Digest. An assessment is carried out after the initial period has passed and is sign of healing are evident, the cast is removed and the patient is required to use a removable brace. Donations to UW Health are managed by the University of Wisconsin Foundation, a publicly supported charitable organization under 501(c)(3) of the Internal Revenue Both types of forces may be exerted, which cause bone displacement alongside tissue traumas. Methods. A fracture can occur in any part of the patella and can vary in severity from a shallow crack to a break that splits the bone into separate pieces. 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. 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. Your knee might be extremely swollen. It is also known as Osteochondritis Dissecans and is common in the knee joint, especially in association with other injuries such as ACL tears. Sometimes the t… The aim of the study was to analyze the clinical results and MRI scans after transpatellar osteochondral fracture fixation following patellar dislocation. 1988 Nov; (236):115-22. von Engelhardt LV, Raddatz M, Bouillon B, et al. The signs and symptoms of a talar dome lesion may include: Chronic pain deep in the ankle—typically worse when HealthTap: Doctor answers on Symptoms, Diagnosis, Treatment, and More: Dr. Beresh on osteochondral fracture patella: The tibial plateu is the part of the top of the tibia that forms the knee joint. Code. [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. It also depends on whether the bone fragment is attached to the area or bone that was injured or loose in the joint. Medial and lateral retinacula disruption may also be present, accompanied by hemarthrosis. Goldberg VM, Figgie HE, Inglis AE, et al. X-ray of the left knee of a 14-year-old boy showing a large defect in the lower half of the patella and at least 2 fragnicnts in the defect.b. Know what is Osteochondral defect, its causes, symptoms, treatment and prevention. [posna.org], In this confusing presentation, a high index of suspicion for patella fracture should be maintained for patients with knee pain and osteoporosis on x-ray with a dysplastic syndrome. Less often, this type of fracture can affect the metatarsal bone of the foot. 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. Fracture of the patella. A fracture can have various degrees of severity and may also be accompanied by damage to the surrounding ligaments, muscles and tendons. [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 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. 1976; 58(2):237-240. 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]. 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. In: Rockwood and Green's Fractures in Adults, Bucholz, RW, Heckman, JD (Eds), Lippincott Williams & Wilkins, Philadelphia 2002; p.1775. Signs and symptoms of a patella fracture Often you will not be able to lift your leg after the injury. [casesjournal.biomedcentral.com], (Hunt 2005) Clinical Findings: Osseous fractures present with a knee effusion, point tenderness at the fracture site, and the inability to extend the knee fully without pain. This can happen when falling from a considerable height. Severe locking or catching syndromeOsteochondral Lesion Picture 1 – Tibial Osteochondral Fracture Finally, open fractures are the severer type: the bone has torn out of the skin and adjacent structures have also sustained massive damage. Nummi J. Fracture of the patella: a clinical study of 707 patellar fractures. Carpenter JE, Kasman R, Matthews LS. Depending on the severity of the fracture, it can be stable, displaced, comminuted or open. An osteochondral defect was identified over the medial facet of patella with a loose osteochondral fragment with very little bone attached to the large cartilaginous part. Depending on the severity of the fracture, there are a number of treatment options ranging from fairly conservative treatments to surgery. 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, A patella fracture usually manifests with intense knee pain and a medical history involving a direct blow to the kneecap, an indirect strain, such as the one sustained by a fall, or a combination of these forces. Patella fractures are a result of direct forces exerted on the patella or indirect forces induced by the surrounding tendons. Operative treatment might also be necessary if patients do not respond well to conservative treatment. How reliable is MRI in diagnosing cartilaginous lesions in patients with first and recurrent lateral. Your joint might pop or stick in one position if a loose fragment gets caught between bones during movement. Patella fractures represent 1% of all traumatizations sustained by the skeleton. Pediatric osteochondral fracture dislocation of the patella is sometimes difficult to diagnose on the basis of physical examination or plain film radiography. [learningradiology.com], tissue swelling diffuse tenderness hemarthrosis of the knee joint is often present high-riding patella or palpable gap at the distal end of the patella indicates disruption of the extensor mechanism motion difficulty with active extension of the knee Acute dislocation of the patella with osteochondral fracture: a review of eighteen cases. This most common symptom of osteochondritis dissecans might be triggered by physical activity — walking up stairs, climbing a hill or playing sports. Moretti B, Speciale D, Garofalo R, et al. A patella fracture is diagnosed with the help of an x-ray obtained at different angles, possibly an MRI and a thorough physical examination. 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 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. 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. It is prone to becoming fractured in high-speed accidents such as those associated with skiing, horse riding, and certain water sports. An orthopedic surgeon should always consider the possibility of infection before proceeding to surgery and treat it appropriately. Patellar fractures are sustained in three different ways. Symptoms After the initial pain and discomfort of a strain or sprain subsides, individuals usually resume or even increase their activity level. 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. 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. Unfortunately, these fractures are often missed on initial radiographs. Berg EE. A period of immobilization might be necessary after surgery. Inflammation in the affected area 3. Includes: possible causes, signs and symptoms, standard treatment options and means of care and support. Aim. Signs and symptoms of a Patellar Fracture include Sharp and sudden pain in the knee, immediately after the injury occurs Swelling, tenderness, and possible bruising around the injury site Typical symptoms include knee pain, regional tenderness and swelling, knee bruises, inability to extend ones knee, defects visible with a bare eye (bone protruding, dislodged patellar pieces) and numbness. There is a lateral and medial part of the joint called the plateu. Lastly, if the traumatization is a result of the two forces combined, fractures of various types can occur, i.e. 3. 1997 Nov; 11(8):573-6. Instability of the respective joint 4. Treatment is variable depending upon the size of the bone fragment, age of the patient and activity level of the patient. Open reduction internal fixation of displaced transverse patella fractures with figure-eight wiring through parallel cannulated compression screws. It is either a result of force directly exerted on the patella itself or occurs when quadriceps forcefully contract. Osteochondral Injuries (PDF) UW Health's Sports Medicine doctors treat a wide range of common athletic injuries. Osteochondral fragment was replaced to the distal part of medial marge of patella as arthroscopically, then retrograde fixed using 2 compressive screws (24x2.7 mm and 26x2.7 mm) from patella to … Radiographic depiction assesses the direction of the fracture, its type, possible comminution and other important features. Fractures that do not involve displacement respond to conservative treatment at a rate of nearly 90%. 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. The tibial plateau is the upper surface of the tibia or shin bone. By presenting our cases we show clinical symptoms, diagnostic pathways and the therapeutic approach for osteochondral fractures of the distal femur. Patella fracture is a frequently observed knee traumatization. Ann Chir Gynaecol Fenn Suppl. The degree of injury ranges from a small crack to a piece of the bone breaking off inside the joint. This injury is more common in adolescents and young adults and typically occurs at the knee, ankle or elbow. Femoral osteochondral fractures are the result of a shearing force when the foot is planted on the ground and the knee twists over the foot. Spontaneous bilateral fracture of patella. 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. 2. Magnetic Resonance Imaging helps to evaluate osteochondral fractures, sleeve fractures [8] and generally fractures that prove difficult to characterize with other than MRI examinations. 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. Fractures of the patella. X-rays obtained from a lateral, anteroposterior and axial perspective are widely used to provide critical information about the skeletal structures underneath tissue. 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. 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. 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. The lateral plateu is the outside oart of the joint. Geriatr Gerontol Int. 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]. the first one involves a direct blow to the patella, usually forceful. Osteochondral Fractures are also sometimes known as articular cartilage injuries. Instr Course Lect. 1964; 34:198–212. Sometimes you can feel multiple pieces of … 2008 Mar; 8(1):55-8. Hence, fractures of the tibial plateau are often associated with injuries to the anterior cr… Swelling and tenderness.

Patella fractures may be treated both surgically and non-surgically, depending on the case. An Osteochondral fracture is a tear of the cartilage which covers the end of a bone, within a joint. The more extensive the damage sustained by the structure, the more time it will require to reach a stage of complete recovery; even less severe traumatizations can result in significant complications, such as patellofemoral arthrosis [5]. Chondral and osteochondral injuries are relatively common in the weightbearing joints of the lower extremity. If the fragment is unstable or loose in the joint, surgery may be necessary to remove and repair the injured area. Treatment options vary based on fracture displacement, classification, and patient factors. 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].
