Posterolateral corner knee children

BACKGROUND: There is an increasing rate of procedures being performed for concomitant injuries during anterior cruciate ligament (ACL) surgery. Few studies have examined risk factors for these associated injuries in young patients. HYPOTHESIS: There are patient-related factors predictive of concomitant knee pathology that differ between age-based cohorts. STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: Natural language processing was used to extract clinical variables from available notes of patients undergoing ACL surgery between 2000 and 2020 at a single institution (5174 ACL surgeries; mean age, 17 ± 4 years; 53...

BACKGROUND: The goal of the osteochondral autograft transplantation (OAT) procedure is to replace both the bone and cartilage that have been compromised by osteonecrosis of the capitellum, a condition known as osteochondritis dissecans (OCD). In children, the vascularity of the capitellum is limited compared with that in adults because the physis acts as a physical barrier to vascular ingrowth from the metaphysis to the epiphysis. The necrotic subchondral bone cannot keep up with the weight-bearing demands of certain high-level athletes such as gymnasts, accumulating microfractures and eventually crumbling...

BACKGROUND: Missed posterolateral corner (PLC) injuries are a known cause of anterior cruciate ligament reconstruction (ACL) failure in the adult population. Failed ACL reconstruction causes significant morbidity in the skeletally immature pediatric population. There is little literature on the character and potential significance of PLC injuries in skeletally immature patients. METHODS: Magnetic resonance imaging studies of the knee at a tertiary care children's hospital for patients who underwent an ACL reconstruction without PLC surgery were retrospectively reviewed...

Combined injury to the anterior cruciate ligament (ACL) and posterolateral structures of the knee is a rare yet increasingly recognized clinical entity. In children or adolescents with open growth plates, this injury pattern is considered to be even more rare than in adults. Because knee ligaments are felt to be stronger than the adjacent physeal plates, the energy of pathologic translational and rotatory stress commonly results in fracture or avulsion injuries rather than ligamentous injury. The appropriate treatment for either injury remains controversial in the skeletally immature patient, with no previously reported case of this combined injury pattern in a patient with open physes...

BACKGROUND: Isolated avulsion fractures of the posterolateral structures (the popliteus tendon, the lateral collateral ligament, and the popliteofibular ligament) of the knee are rare. PURPOSE: To describe the outcome after an isolated avulsion fracture at the femoral attachment of the posterolateral structures in skeletally immature patients and to communicate our clinical experience concerning diagnosis and treatment. STUDY DESIGN: Case series; Level of evidence, 4...

OBJECTIVES: This study aimed to assess the results of knee capsulotomy for correcting fixed knee flexion contracture in children with cerebral palsy (CP). METHODS: Thirty-five children (20 boys, 15 girls; mean age 13.5+/-2.5 years) with CP underwent posterior knee capsulotomy for 59 knees. Eleven patients had diplegia, one patient had hemiplegia, and 23 patients had quadriplegia. There were two community ambulators (3 knees), 19 household ambulators (33 knees), and 14 nonambulators (23 knees)...

PURPOSE: This study was undertaken to document the clinical results and technical aspects of arthroscopic partial meniscectomy in conjunction with peripheral tear repair for the treatment of symptomatic discoid lateral meniscus in children. METHODS: From June 1998 to May 2005, the senior author (J.H.A.) performed arthroscopic surgery on 77 children (89 knees) with symptomatic discoid lateral meniscus. Of these patients, we retrospectively studied 23 patients (28 knees) with a peripheral tear that was treated by partial central meniscectomy in conjunction with peripheral suture repair...
