If an osteochondral lesion has occurred, however, everyday activities that put pressure on the joint, may lead to pain and swelling, although the joint usually is fine when at rest. A patient also needs to be evaluated for the presence of hemarthrosis and damage to the extensor mechanism, namely the medial and lateral retinacula. J Orthop Trauma. 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. Symptoms: Unless the injury is extensive, it may take months, a year or even longer for symptoms to develop. Finally, open fractures are the severer type: the bone has torn out of the skin and adjacent structures have also sustained massive damage. Patella fractures may be treated both surgically and non-surgically, depending on the case. The aim of the study was to analyze the clinical results and MRI scans after transpatellar osteochondral fracture fixation following patellar dislocation. A patella fracture is diagnosed with the help of an x-ray obtained at different angles, possibly an MRI and a thorough physical examination. [orthobullets.com], On this presentation, examination revealed that she had a marked knee effusion with a functional extensor mechanism and a range of motion from 0-60 degrees. 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. 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. Typically, indirect fractures are a result of abnormal or excessive knee flexion. 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. How reliable is MRI in diagnosing cartilaginous lesions in patients with first and recurrent lateral.

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 Berg EE. 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]. UW Health's Sports Medicine doctors treat a wide range of common athletic injuries. 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. Stable fractures are those whereby the two separated parts remain in place and correct alignment. [orthobullets.com], (Hunt 2005) Imaging AP/lateral radiographs can be difficult to interpret if the reader does not actively look for a patellar sleeve, as the bony component of the fracture may be very small. 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. Generally, fractures where the patella has broken but all the damage is minimal and the segments still remain in their original place does not need surgery. Sometimes you can feel multiple pieces of … Gradual strengthening of the arthrosis should be attempted alongside physiotherapy to restore the range of movement.

Other areas affected include under the patella (knee cap) or along the talus bone in the ankle. 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. 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. Carpenter JE, Kasman R, Matthews LS. [ncbi.nlm.nih.gov], […] more often girls Other possible causes of anterior knee pain include: Arthritis Pinching of the inner lining of the knee during movement (called synovial impingement or plica syndrome) Symptoms Anterior knee pain is a dull, aching pain that is most often J Bone Joint Surg Br. 1988 Nov; (236):115-22. von Engelhardt LV, Raddatz M, Bouillon B, et al. Treatment options vary based on fracture displacement, classification, and patient factors. Operative treatment might also be necessary if patients do not respond well to conservative treatment. This can happen when falling from a considerable height. 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. 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]. 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. Pain. Displaced fractures usually present with abnormal appearance of the knee and the dislocated pieces may as well be palpable. The patella bone is otherwise known as the "kneecap" bone.
