{"title":"Epidemiology of Patella Instability Injuries in Collegiate Level Athletes in the United States","authors":"Christine S. Williams","doi":"10.46889/josr.2022.3213","DOIUrl":"https://doi.org/10.46889/josr.2022.3213","url":null,"abstract":"Objective: Patella instability injuries are often sports-related and occur in young athletes. These injuries severely impact the season and career trajectory of high-level competitors. This is the first large epidemiological study that evaluates these injury events in NCAA athletes.\u0000\u0000Methods: Patellar instability injuries across 16 sports among NCAA men and women during the 2004-05 to 2013-14 academic years were analyzed using the NCAA Injury Surveillance Program (NCAA-ISP). Patellar instability injuries per 100,000 Athlete-Exposures (AEs), operative rate, annual injury and reinjury rates, in-season status (pre/regular/post-season) and time lost were compiled and calculated.\u0000\u0000Results: A total of 11,778,265 Athlete-Exposures (AE) were identified and included. 380 patellar instability injuries were identified (Injury Rate IR = 3.23 per 100,000 AEs). 91 (23.95%) were severe injuries with a significantly higher time loss from play (40.5 days) and risk of operative management (50.55%). The most common sports during which a patellar instability event occurred were Women’s Gymnastics (IR=7.87), Soccer (IR=5.83), and Basketball (IR=4.34) and Men’s Wrestling (IR=5.44), Football (IR=4.84), and Soccer (IR=3.06). Male athletes had a statistically significant higher risk of season or career-ending injuries in all patellar instability injuries (3.20% vs 0.89%, p=0.0013). Severe injuries were more likely to result from contact mechanisms (58.24% vs 40.66%).\u0000\u0000Conclusion: Patella instability injuries have a profound impact on the longevity and sustainability of a collegiate athletes’ career. The risk of recurrence once a patellar injury has occurred is significant and athletes often require surgery. While more female athletes sustained these injuries, male athletes were more likely to require operative management and sustain a season-ending injury.","PeriodicalId":382112,"journal":{"name":"Journal of Orthopaedic Science and Research","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131080856","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The integrative approach considers the neuromechanical coupling in respiration, introducing the concept of pneumofascial competition (section one) as the loop that occurs between inspired air and pleural fasciae and then global myofascia. Affordances (possibilities) and constraints of respiratory system match positions and movements of whole body, where the links between spine and periphery (limbs and head) play a determinant part: these connections, the one that involves the spinal transverse plane, are worked out in section two. Therefore, section two appears a decisive step in trying to solve some questions about human bipedal locomotion and its proficiency, again in a neuromechanical coupling view, with totally original considerations about the role of scapula and about the spine as a treble torsion spring. Finally, it is possible to trace out a new adolescent idiopathic scoliosis etiology (section three), adding a third factor: laterality. What is only human is the hyper stressed lateralization (s) by means of cultural requirements. The motor hyper specialization is another form of energy saving (automatism). Thus, all the article is about the evolutionary principle of costs minimizing. Adolescent idiopathic scoliosis is here seen as an evolutionary mismatch disease between human nature and human culture and every curve can be explained in an integrative way, where causes and effects develop a mutual self-powering cycle.","PeriodicalId":382112,"journal":{"name":"Journal of Orthopaedic Science and Research","volume":"962 ","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-07-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132948693","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Dysplastic odontoid is one of the prominent aetiologies behind the development of atlanto-axial instability which eventually leads to morbid vertebrogenic myelopathy.\u0000\u0000Material and Methods: We describe 10 children (7 boys and 3 girls) with the phenotype/genotype of Morquio´s syndrome (MPS IVA). Lumbar kyphosis occurs at the age of six months, followed by apparent waddling gait at the age of 3 years. Clinical phenotype and genotype are the baseline tools to set up a crystal clear long term management. Firstly, we proceed via clinical assessment of C1-2 instability. The latter is carried out with full dynamic lateral cervical spine radiographs. Instability can be visualized through the precise interpretations of the anatomical structures around the atlanto-axial segments. 3D sagittal CT scan has been applied to further localize the exact pathology. In 7 cases, there was an initial myelopathy at the level of the cranio-vertebral junction.\u0000\u0000Results: The most threatening complication of MPS IVA is the vertebrogenic myelopathy. The latter emerged as a notorious complication in connection with atlanto-axial instability and progressive thickening of the spinal cord due to accumulation of Glycosaminoglycan (GAGs). Vertebrogenic myelopathy have been encountered in seven children. All underwent decompression and stabilization of the cervical spine\u0000\u0000Conclusion: Patients with MPS IV, in their first year of life usually manifest growth deficiency and lumbar kyphosis, but unfortunately passed unnoticed by most of the paediatricians. Progressive dysplasia of the acetabulae is the reason behind the waddling gait. The misconception of generalized ligamentous hyper laxity accompanied with waddling gait were the main incentives of confusion among most of the paediatricians and physicians. Thereby, the false diagnosis of Duchenne Muscular dystrophy has been falsely considered by some colleagues. The purpose of this paper is threefold. First, overlooking the early mal-development of the backbone (lumbar kyphosis) is not a simple mistake. Second, marked ligamentous hyperlaxity warrants the attention toward cervical ligaments, and as ligaments are the main supporters of the craniocervical junction and spine stability, such abnormality demands prompt clinical attention. Third, is to assess the vertebral pathology and vertebrogenic myelopathy from the standpoint of syndromic assessment and the efficiency of decompression and stabilization operations.","PeriodicalId":382112,"journal":{"name":"Journal of Orthopaedic Science and Research","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132879187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studies revealed that the vast majority of patients with CCHS are free from any associated pulmonary, cardiac or brainstem pathologies.\u0000\u0000Material and Methods: F.R is a 20 -year-old- Austrian-girl presented in my consultation seeking advice for her unpleasant clinical history. In her early life, seizures were the first serious clinical presentation. Followed later on with hypertension, bouts of respiratory dysfunction and impairment of consciousness. In 2019 she underwent surgical intervention to remove a 2 cm hamartoma (posterior upper aspect of the right thigh). Few years later, another hamartoma on the ventral side of the tongue has been identified as well. Early on, she received the diagnosis of Mediterranean fever syndrome and the geneticist encountered homozygosity to the MEFV M694V mutation as the reason behind the constellation of the current unpleasant symptomatology. Later on a presumptive diagnosis of Ehlers-Danlos syndrome-hypermobile type has been suggested in other Medical Institutions. We proceeded with our documentation via clinical and radiological phenotypic characterizations.\u0000\u0000Results: Clinical examination showed growth above the 97th percentile (overgrowth) with no specific facial dysmorphic features. She manifested generalized ligamentous hyper laxity. Her ligamentous hyperlaxity was compatible with 6 points out of 9 in correlation with Beighton scoring test. On the bases of skeletal survey; lateral skull radiograph showed features of mastoid and temporal bone characterized with extensive-pneumatization. Axial CT scan shows bilateral hyper-pneumatization of the temporal bones, demonstrating expansion of aerial spaces with loss of the bony trabeculae and thinning of the mastoid bone. Mastoid cells appear to be in communication with a large intracranial epidural air cavity in the temporal and parietal regions. Reformatted CT scan of temporal bone, through coronal and axial images, at the level of the cavum tympani and the mastoid, showed a defect in the right tegmen appeared as cloudy/ opaque lesions around the cavum and the surrounding air cells. Contrast- enhanced computed CT angiography of the cervical and cerebral vasculature showed unusual malalignment and spiral twisting along several vascular segments resulted in the mal-development of basilar artery stenosis without atherosclerosis. The current patient manifested overgrowth syndromic entity with a constellation of osseous and vascular abnormalities resulted in a clinical course of congenital central hypoventilation syndrome.\u0000\u0000Conclusion: The etiology behind the extension of pneumatization has most likely occurred because of defective ossification of the occipito-mastoid synchondrosis .

Several methods of medial soft tissue balancing in the varus knee during total knee replacement surgeries have been reported. Traditionally, they included releasing the superficial Medial Collateral Ligament (sMCL) in severe varus cases by several methods. However, this release can create instability in the knee. The aim of this study was to create an algorithm for soft tissue release in varus osteoarthritic knees and to evaluate its efficacy in achieving intraoperative gap balancing without releasing the superficial MCL.\u0000\u0000Materials and Methods: One hundred and five varus osteoarthritic knees who received primary posterior stabilized total knee arthroplasties between October 2015 and January 2016 were included in this study. Varus deformities ranged between 10 to 40 degrees. Sequential balancing was done into 5 steps: step 1 – releasing of deep MCL, step 2 – excision of osteophytes, step 3 – excision of scarred tissue in the posteromedial corner, step 4 – excision of the posteromedial capsule and step 5 – release of semimembranosus. The V-STAT® Variable Soft Tissue Alignment Tensor was used to ensure a balanced medial and lateral gap following each step. Once the gaps were balanced, no further soft tissue release were carried out.\u0000\u0000Results: All knees were balanced without releasing the superficial MCL ligament. The maximum release step necessary was: step 1 (0 cases), step 2 (31 cases), step 3 (35 cases), step 4 (25 cases) and step 5 (14 cases).\u0000\u0000Conclusion: Superficial medial collateral ligament should not be released during intraoperative varus knees soft tissue balancing in posterior stabilized total knee arthroplasties.
