EditorInformation Osteochondral injury after acute patellar dislocation in children and adolescents. First, Although the sample size was large enough to show a statistically significant difference between the groups, the number of patients was small. Depending on the severity of the fracture, there are a number of treatment options ranging from fairly conservative treatments to surgery. Johnson DS, Turner PG. Osteochondral fracture of the lateral femoral condyle is a rare intra-articular injury with or without patellar dislocation. During the study period from October 2012 to December 2018, medical records of 87 patients with first time acute patellar dislocation were identified. The incidence of osteochondral fractures with ACL injuries may be as high as 80% [20, 21]. whereas, consensus for treating APD with OCF has not been established yet because of limited research comparing surgical and non-surgical initial management for people having dislocated patella with OCF .

Conformance level of PDF/A standard Whereas, some of the patients with large OCFs (five patients with OCFs of the inferomedial facet involving central ridge) had finally failed of conservative treatment due to recurrent patellar dislocation episodes during conservative treatment protocol.

In the subgroup of patient with OCF of the inferomedial facet of the patella, the fragments were found in the lateral gutter and did not cause pain or mechanical symptoms. If further exposure of the articular surface of the patella is needed to repair osteochondral fragments, a vertical incision extending from the traumatic tear in the lateral retinaculum may enable the patella to be everted 90 degrees.6 Alternatively, Berg7 described the use of tibial tubercle osteotomy to expose comminuted patella fractures. 2009;25(6):620–5. XMP Media Management Schema 2004;27(10):1058–62. The patella is formed from the fusing of ossific nuclei. Treatment Screws and Kirschner wires both absorbable and nonabsorbable have been the common mode of fixation of these fractures. 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.

Thus, results could not reflect mid- or long- term outcomes. treatment is either immobilization or surgery depending on diplacement and knee extension function. A retrospective study was performed on the use of bioabsorbable pins in the fixation of osteochondral fractures (OCFs) after traumatic patellar dislocation in children. Functional outcomes of each group were assessed using the Kujala score and International Knee Documentation Committee Subjective Knee Form (IKDC SKF) questionnaire at initial presentation and final follow-up [23, 24].
