Research progress of lower limb muscle strength training in the treatment of lliotibial band syndrome / 中国骨伤

Iliotibial band syndrome (ITBS), as an overused injury of the lower extremities, has developed into a common cause of lateral knee pain. At present, the treatment of ITBS includes drug therapy, muscle strength training, physical therapy, and surgical treatment. Among these methods, physical therapy, drug therapy, and surgical treatment can only alleviate the symptoms of patients. As a safe and effective treatment, lower limb muscle strength training can improve patients' muscle strength, correct abnormal gait, and reduce the recurrence rate of the disease by paying attention to the dynamic changes of patients' recovery process. At present, the pathogenesis of ITBS remains unclear, and the treatment methods are not unified. It is necessary to further study the biomechanical factors related to the lower extremities and develop more scientific and comprehensive muscle strength training methods.

Métodos: La búsqueda y análisis de la información se realizó en un periodo de 92 días (01 de julio al 30 de septiembre de 2020). Se emplearon las siguientes palabras: iliotibial band syndrome, iliotibial band friction syndrome AND lateral knee pain. Se realizó una revisión bibliográfica de un total de 186 artículos publicados en las bases de datos PubMed, Hinari, SciELO y Medline mediante el gestor de búsqueda y administrador de referencias EndNote, de ellos se utilizaron 40 citas seleccionadas para realizar la revisión, 38 de los últimos cinco años. Desarrollo: Se mencionan las características anatómicas más importantes relacionadas con la banda iliotibial. Se refiere a las maniobras empleadas, así como los exámenes imagenológicos de mayor utilidad. Se exponen las principales entidades implicadas en el diagnóstico diferencial. Con relación al tratamiento se mencionan las modalidades conservadoras y quirúrgicas. Conclusiones: El síndrome de la banda iliotibial es una enfermedad que tiene como característica fundamental dolor lateral de la rodilla el cual aumenta con la actividad física. El tratamiento conservador constituye la primera línea y el quirúrgico está justificado a los seis meses de respuesta limitada a la primera modalidad del enfrentamiento terapéutico(AU)

Introduction: Knee pain responds to multiple causes such as the iliotibial band syndrome that mainly affects young patients who practice certain sports activities. Objective: To update and offer information on iliotibial band syndrome. Methods: The search and analysis of the information was carried out in a period of 92 days - from July 1 to September 30, 2020, with the words iliotibial band syndrome, iliotibial band friction syndrome AND lateral knee pain. A bibliographic review of 186 articles published in PubMed, Hinari, SciELO and Medline databases was carried out using the EndNote search manager and reference manager, Forty citations were selected to perform the review, 38 of them were from the last five years. Development: The most important anatomical characteristics related to the iliotibial band are mentioned. They refer to the maneuvers used, as well as the most useful imaging tests. The main entities involved in the differential diagnosis are presented. Regarding treatment, conservative and surgical modalities are mentioned. Conclusions: The iliotibial band syndrome is a disease, main characterized by lateral knee pain, which increases with physical activity. Conservative treatment constitutes the first option; in addition, surgical treatment is justified after six months of limited response to the first option of therapeutic management(AU)

Synovial Cyst: A Culprit for Recalcitrant Iliotibial Band Syndrome: A Case Report

We present the case of a 56-year old gentleman who presented with recalcitrant iliotibial band (ITB) friction syndrome which did not improve with various modalities of conservative treatment. Magnetic Resonance Imaging (MRI) of the affected knee did not show pathology typical of ITB friction syndrome. However, open exploration revealed a synovial cyst deep to the iliotibial band, abutting against the anterolateral capsule. The presence of distinctive clinical signs on physical examination should alert clinicians to consider knee synovial cyst as a differential diagnosis when dealing with recalcitrant ITB syndrome.

Intra-Articular Fibroma of Tendon Sheath in a Knee Joint Associated with Iliotibial Band Friction Syndrome

Iliotibial band (ITB) friction syndrome is a common overuse injury typically seen in the active athlete population. A nodular lesion on the inner side of the ITB as an etiology or an accompanying lesion from friction syndrome has been rarely reported. A 45-year-old male presented with recurrent pain and a movable nodule at the lateral joint area, diagnosed as ITB friction syndrome. The nodule was confirmed as a rare intra-articular fibroma of the tendon sheath (FTS) on the basis of histopathologic findings. We describe the MRI findings, arthroscopic and pathologic features, in this case of intra-articular FTS presenting with ITB friction syndrome.

Diagnosis of Iliotibial Band Friction Syndrome and Ultrasound Guided Steroid Injection

A 64-year-old woman visited our pain clinic with the pain of right lateral side of thigh for one year. Her pain always started from knee and was radiated to buttock area when symptom was severe. She showed significant tenderness at knee lateral side and local tightness at lateral thigh. Magnetic resonance image of the knee was performed and we could identify high signal intensity of iliotibial band through coronal and axial view. In spite of medication and physical stretching exercise of iliotibial band for one month, she did not show any improvement of pain. To alleviate her symptom, ultrasound guided local corticosteroid injection targeting beneath the iliotibial band was performed. After the procedure, the reduction of pain was significant and there was no need for further management.

Running Injuries

Running is becoming one of the most popular leisure sports. Part of the growing popularity of running is its easy accessibility and health benefits. The incidence of running injuries rates ranges from 37% to 56%, which incidence rate is still 2 to 6 times lower than in all other sports. Most running injuries are musculoskeletal overuse syndrome of the lower extremity. The risk factors of running injuries can be training errors, improper running surface, worn shoes, body flexibility, prior injury. The knee is the most common site of injury and accouts for 25% to 33% of all, and pa-tellofemoral stress syndrome is the most common known as runner's knee. Iliotibial band syndrome, medial tibial stress syndrome, plantar fascitis, Achilles tendinitis, stress fracture are common injuries in runners. The physical examination includes a biomechanical screening to identify related imbalances. Additionally, each runner is observed walking and running. This comprehensive, running specific approach to diagnosis can be helpful in developing optimum rehabilitation program.

Rehabilitation of Running Injuries

Running is becoming one of the most popular leisure sports. The growing popularity of running is due in part to its easy accessibility and health benefits. The incidence of running injuries ranges from 37% to 56%, which is still 2 to 6 times lower than in other sports. Most running injuries are musculoskeletal overuse syndrome of the lower extremities. The risk factors of running injuries include training errors, improper running surface, worn shoes, body flexibility, and prior injury. The knee is the most common site of injury and accounts for 25% to 33% of all, and patellofemoral stress syndrome is most commonly known as 'runner's knee'. Iliotibial band syndrome, medial tibial stress syndrome, plantar fascitis, Achilles tendinitis, and stress fracture are all common injuries among runners. The process of rehabilitation is to be divided into four stages according to the athlete's level of function; the initial stage, intermediate stage, advanced stage, and final stage.
