osgood schlatter

Osgood-Schlatter disease (OSD), a condition that affects adolescents, causes inflammation, pain, and prominence at the tibial tuberosity. The causes of OSD are not well understood, but eccentric contractions in the quadriceps have been suggested as a possible factor. To investigate this, a study was conducted in which 24 rats were divided into two groups: the downhill treadmill running (DR) group and the control (CO) group. The DR group underwent a preliminary running program for 1 week, followed by a main running program for 3 weeks...

A limp is a deviation from normal gait pattern, with pain as the presenting feature in about 80% of cases. The differential diagnosis is broad and includes congenital/developmental, infectious, inflammatory, traumatic (including nonaccidental), and, less commonly, neoplastic etiologies. Transient synovitis of the hip is the cause of a limp in the absence of trauma in 80% to 85% of children. It can be differentiated from septic arthritis of the hip by the absence of fever or ill-appearance and with laboratory testing that shows normal or only mildly elevated inflammatory markers and white blood cell count...

PURPOSE OF THE STUDY Osgood-Schlatter disease develops secondary to chronic patellar tendon overloading. The present study was designed to determine whether athletes with Osgood-Schlatter disease perform significantly worse in the Y-Balance Test compared to healthy subjects in a control group. MATERIAL AND METHODS The study involved ten boys (average age 13.7 years). Seven participants had bilateral knee pain, swelling and tenderness whereas three had unilateral knee pain, swelling and tenderness (left knee in two cases, and right knee in one)...

BACKGROUND: Long-standing knee pain is one of the most common reasons for adolescents (aged 10-19 years) to consult general practice. Generally, 1 in 2 adolescents will continue to experience pain after 2 years, but exercises and self-management education can improve the prognosis. However, adherence to exercises and self-management education interventions remains poor. Mobile health (mHealth) apps have the potential for supporting adolescents' self-management, enhancing treatment adherence, and fostering patient-centered approaches...

OBJECTIVES: To describe the Quality of Life (QoL) among adolescents with Patellofemoral Pain (PFP) and Osgood-Schlatter Disease (OSD) and investigate characteristics associated with QoL. STUDY DESIGN: Cross-sectional. PARTICIPANTS: 316 adolescents with PFP or OSD. MAIN OUTCOME MEASURES: QoL subscale of The Knee injury and Osteoarthritis Outcome Score (KOOS) and the EuroQol 5-dimensions (EQ-5D). RESULTS: The KOOS-QoL was 51 ± 18, and the total index score for the EQ5D was 0...

PURPOSE: This study aimed to elucidate the influential predictive risk factors of Osgood-Schlatter disease (OSD) on the support (non-kicking) leg among adolescent soccer players considering peak height velocity (PHV) age and investigate the cut-off values of the predictive variables. METHODS: A cohort of 302 Japanese adolescent male soccer players aged 12-13 years were followed over 6 months. All players underwent physical examination, tibial tubercle ultrasonography, anthropometric and whole-body composition measurements, and muscle flexibility test of the support leg at the baseline...

Genu recurvatum associated with Osgood-Schlatter disease (OSD) has been reported in several studies. In this report, we describe a rare complication of a case of OSD with flexion contracture (tfighat is the exact opposite of the knee deformity classically associated with OSD) and increased posterior tibial slope. In the current article, we report a 14-year-old case of OSD referred to our center with a fixed knee flexion contracture. Radiographic evaluation revealed a tibial slope of 25 degrees. There was no limb length discrepancy...

BACKGROUND: The aim of the study was to evaluate the effect of Osgood-Schlatter disease (OSD) on knee joint function in elite young soccer players. Our hypothesis was that knee joint function in elite young soccer players was impaired following OSD compared with soccer players with no history of OSD. METHOD: In young male soccer players (n = 36) from elite academies (mean ±SD, age: age: 15,3 ± 1,7 years; height: 1,7 ± 0,06 m; weight: 63,5 ± 8 kg; BMI: 20,7 ± 2)...

We present basic differences in the musculoskeletal ultrasound examinations between adults and children. Examiners who deal with adults on a daily basis have shared concerns about examining children. Such concerns may arise from the different approach to child ultrasounds, but they also come from differences in anatomical characteristics according to developmental age. We discuss the presence of growth plates, as well as non-mineralized parts of the bones. We also refer to the pathologies most often found in ultrasounds in early developmental stages...

Stress injuries to the bone and physis of the knee are common in the active adolescent patient and can be broken down into bone stress injuries (BSIs) and chronic physeal stress injuries. BSIs result from prolonged, repetitive bone loading, whereas chronic physeal stress injuries develop from repetitive loading to the apophysis or epiphysis. Most stress injuries of the knee resolve with relative rest but will occasionally need surgical intervention in more severe cases. Early and accurate identification is paramount for optimal management and to avoid long-term consequences...

Background: Osteochondromas are a relatively common primary bone tumor, which may share common clinical features with Osgood-Schlatter disease (OSD). A limited number of cases have described tumors misdiagnosed as OSD. Case Presentation: We report the case of an 11-year-old male with a sessile osteochondroma of the tibial tubercle and concomitant involvement of the distal extension and attachment of the patellar tendon into the tibial periosteum. A prior diagnosis OSD had been made...

PURPOSE: The Knee Injury Osteoarthritis Outcome Score for children (KOOS-Child) is a self-administered, valid and reliable questionnaire for children and adolescents with knee disorders such as Osgood Schlatter disease, anterior knee pain, and patella dislocation. This study aimed to cross-culturally adapt the German version of the KOOS-Child questionnaire and test the reliability in two groups of children, one treated conservatively and the other surgically. METHODS: A forward-backward translation of the original questionnaire into the German language was conducted...

Overuse injuries are well described for both upper and lower extremities among skeletally immature athletes. To our knowledge, there is no description in the literature of an overuse injury affecting the medial tibial physis that is different from the typical Osgood-Schlatter disease or tibial tubercle apophysitis. In this article we present a 13-year-old athlete with medial proximal tibial widening or epiphysiolysis from overuse playing soccer. We need to be aware that with increased early sports specialization we may see injuries we have not seen before...

Genu recurvatum (GR) is defined as knee hyperextension greater than 5°, with the normal physiological accepted limits of up to 10 to 15° of extension. Physiological GR is commonly bilateral, symmetrical, and mostly asymptomatic. Pathologic GR is usually asymmetric, symptomatic, and can be congenital or acquired. Acquired GR can be classified according to the origin of the deformity into pure osseous, soft tissue, and combined types. Symptomatic GR can present with anterior knee pain and/or instability. Surgery is generally indicated in symptomatic (pain, instability), pathologic GR with an associated causative correctible deformity (bony, soft tissue, or a combination of both)...

Osgood-Schlatter disease is the most common osteochondritis of the lower limb in sport-practicing children and adolescents. Its manifestation usually coincides with the appearance of the secondary ossification center of the tibia and is linked to the practice of sports with an explosive component. In the present study, a review of the factors related to its appearance, diagnosis and treatment was carried out. Its appearance seems to be multifactorial and related to multiple morphological, functional, mechanical and environmental factors...

The etiology and etiopathogenesis of Osgood-Schlatter Disease (OD) are not fully understood. The aim of this review is to systematically analyze the available literature about the etiology and risk factors of OD. The literature was systematically reviewed using the PRISMA criteria to evaluate all studies published in the last 25 years (between 1996 and 2021) dealing with the etiology of OD. A total of 16 articles were included. The etiology and risk factors of OD are controversial. The main articles focused on muscular factors (mainly tightness of the rectus femoris), alteration of the patellar tendon or extensor mechanism, mechanical factors (repetitive solicitation, trauma, sports), tibial anatomy (tibial slope or tibial torsion), and histological alteration...

Arthroscopic resection of symptomatic unfused tibial tubercle ossicles causing chronic anterior knee pain due to recalcitrant Osgood-Schlatter disease has been shown to be a reproducible arthroscopic technique. Although a number of other surgical techniques have been described, including ossicle excision and tubercle-plasty, drilling of the tibial tubercle, bone peg insertion to induce fusion, open excision of loose fragments, direct bursoscopic ossicle resection, and closing-wedge tubercle osteotomy, with varied outcomes, this technique offers a minimally invasive approach with low risk...

Osgood-Schlatter disease commonly affects physically active adolescents. It is a common cause of anterior knee pain and inflammation in this population. Its symptoms typically subside with conservative therapy. Surgery, including resection of mobile ossicles, is considered when the pain persists on kneeling or during sports after the skeletal maturity. In this procedure, we use a direct bursoscopic approach with ultrasound-guided ossicle resection. In comparison with the classical arthroscopic approach, the bursoscopic approach uses more distally placed portals...

BACKGROUND: The relationship between hamstring flexibility and the risk of OSD continues to be a debate, and whether hamstring stretching exercises should be considered as one of the conservative treatments of OSD is still unclear. OBJECTIVES: To investigate the relationship between hamstring flexibility and the risk of OSD by assessing the changes of loading on the tibial tuberosity caused by the changes of hamstring optimal lengths. METHODS: Experimental data of a young adult running at 4 m/s were used, which were collected by an eight-camera motion capture system together with an instrumented treadmill...

Background: Deep infrapatellar bursitis (DIB) has been detected in cases of Osgood-Schlatter disease (OSD). However, the clinical implications of DIB in the apophyseal stage, during the period when OSD has not yet developed, remain unclear. Purpose: To investigate the factors related to DIB in the apophyseal stage in preadolescent baseball players. Study Design: Cross-sectional study, Level of evidence, 3. Methods: The study participants were junior baseball players who participated in a medical checkup in 2020...
