Iliotibial band

BACKGROUND: Despite the numerous health benefits of distance running, it is also associated with the development of 'gradual onset running-related injuries' (GORRIs) one of which is Iliotibial Band Syndrome (ITBS). Novel risk factors associated with a history of ITBS (hITBS) have not been described in a large cohort of distance runners. OBJECTIVE: To identify risk factors associated with hITBS in distance runners. DESIGN: Descriptive cross-sectional study...

BACKGROUND: To assess the incidence of anterolateral ligament (ALL) and Kaplan fiber of the iliotibial band (KF) injuries in patients with acute anterior cruciate ligament (ACL) injury on magnetic resonance imaging (MRI), and to investigate the association between these injuries and the magnitude of preoperative pivot-shift test. METHOD: One-hundred and five patients with primary ACL injury were retrospectively reviewed. ALL injury and KF injury were assessed by preoperative MRI, and subjects were allocated into four groups: Group A, neither injury; Group B, only ALL injury; Group C, only KF injury; Group D, simultaneous ALL and KF injuries...

BACKGROUND: The pendulum test is a quantitative method used to assess knee extensor spasticity in humans with spinal cord injury (SCI). Yet, the clinical implementation of this method remains limited. The goal of our study was to develop an objective and portable system to assess knee extensor spasticity during the pendulum test using inertial measurement units (IMU). METHODS: Spasticity was quantified by measuring the first swing angle (FSA) using a 3-dimensional optical tracking system (with external markers over the iliotibial band, lateral knee epicondyle, and lateral malleolus) and two wireless IMUs (positioned over the iliotibial band and mid-part of the lower leg) as well as a clinical exam (Modified Ashworth Scale, MAS)...

PURPOSE: The aim of the present systematic review was to quantitatively synthesize the best literature evidence regarding osteoarthritis developing after anterior cruciate ligament reconstruction (ACLR), including only studies with a follow-up duration of at least 20 years. MATERIAL AND METHODS: A systematic review was conducted based on the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines on four electronic databases (PubMed, Scopus, EMBASE and Cochrane Library)...

OBJECTIVES: Arthroscopic treatment is indicated for external snapping hip (ESH) syndrome in patients refractory to conservative treatment, but snapping does not disappear completely in some case. No previous studies have described the clinical course of ESH syndrome in patients who presented with persistent snapping after an arthroscopic procedure. We demonstrated the clinical outcomes following an incomplete arthroscopic iliotibial band (ITB) release for ESH syndrome. METHODS: This retrospective observational study was performed at two teaching hospitals between October 2015 and December 2021...

Diminished hip labrum size and tissue quality may be a predictor of poor patient outcomes when a nonaugmented primary labrum repair is performed. Labrum augmentation is an option for patients with hypoplastic or degenerative labral tissue. The optimal graft for augmentation has yet to be identified, and biomechanical research shows no difference in force to suction seal disruption between dermal allograft and iliotibial band allograft when used to augment the labrum. However, time zero biomechanical studies do not reflect biological ability of the graft to heal to surrounding structures, revascularization of the graft, durability of the graft, hip capsular status, and response to functional demands of the patient...

BACKGROUND: Unilateral osteoarthritis (OA) affects single knees and presents a unique scenario where individuals experience varying degrees of symptoms between their affected and unaffected knees. OBJECTIVE: This study aims to investigate differences in muscle tightness between symptomatic and asymptomatic knees in individuals with unilateral knee OA while exploring the interplay among pain, functionality, and muscle tightness. METHODS: In this cross-sectional study, thirty knee OA patients underwent assessments for hamstring (Active Knee Extension, Straight Leg Raise), iliotibial band (Ober Test), and quadriceps tightness (Modified Thomas Test)...

Isolated lateral-sided knee pain is a unique problem following total knee arthroplasty (TKA). Reported causes include soft tissue impingement against extruded cement, an overhanging tibial tray, remnant osteophytes rubbing against the iliotibial band (ITB), popliteal tendon impingement, fabella syndrome, and synovial tissue impingement in the lateral gutter. In addition, iliotibial band traction syndrome secondary to guided motion Bi-cruciate stabilizing knee arthroplasty has been recognized as a new clinical entity...

This classic discusses Marcel Lemaire's (1918-2006) original publications in the context of modern surgical practice, including a description of his original lateral extra-articular tenodesis. Previously published in French, these translations shed light on his revelations regarding the ACL's role in knee stability and his detailed insights into the "ressaut rotatoire" or the pivot-shift phenomenon. We track the evolution of Lemaire's procedure since the publication of his original technique in 1967 which used a nylon cord superficial to the LCL followed by cast immobilisation for one month...

KEY CLINICAL MESSAGE: We highlight the rare case of an atraumatic, intra-articular ganglion cyst of the lateral knee deep to the iliotibial band that was successfully treated nonoperatively, a pathology yet to be reported in orthopedic literature. ABSTRACT: Ganglion cysts are mucin-filled synovial cysts commonly found on the dorsal surface of the hands and feet. Intra-articular ganglion cysts of the knee are rare, and when they present clinically, are typically treated operatively through arthroscopic surgery...

A lateral opening-wedge distal femoral osteotomy is useful to offload the lateral tibiofemoral compartment for focal chondral defects or isolated lateral compartment arthritis. Although beneficial for these lateral compartment disorders, a distal femoral osteotomy requires careful forethought to optimize correction accuracy and safety. We recommend the following for effective execution of a distal femoral osteotomy: (1) Plan the desired correction preoperatively while accounting for an individual patient's anatomy and femoral width...

PURPOSE: To investigate whether allograft substitutes may be used to restore suctional seal properties with labral augmentation, the purpose of the current study was to evaluate the biomechanical properties of the labral suction seal under several scenarios, including: (1) intact labrum, (2) rim preparation, (3) labral repair, (4) labral augmentation with iliotibial band (ITB), and (5) labral augmentation with a dermis allograft. METHODS: Eleven hemi-pelvises were dissected to the level of the labrum and placed in a material testing system for biomechanical axial distraction...

BACKGROUND: Lateral extra-articular procedures are becoming increasingly popular in association with anterior cruciate ligament (ACL) reconstruction, especially in patients with persistent rotatory instability and in a high-risk population. However, few studies have investigated the outcomes of the lateral extra-articular procedure as an associated procedure in an ACL revision (R-ACLR) setting and its benefit with respect to isolated intra-articular reconstruction. HYPOTHESIS: Lateral extra-articular procedures reduce the failure rate of revision ACL reconstruction (R-ACLR)...

BACKGROUND: The lateral extra-articular tenodesis (LET) procedure associated with anterior cruciate ligament (ACL) reconstruction can be considered in selected patients to diminish the risk of persistent rotatory instability and achieve a protective effect on the graft. Several techniques have been described in the literature to treat rotatory instability. Usually, a strip of the iliotibial band (ITB) is harvested from its middle while leaving the distal insertion, then passed underneath the lateral collateral ligament and fixed on the lateral aspect of the distal femur with various fixation methods such as staples, screws, anchors or extracortical suspensory devices...

Hip and knee injections are useful diagnostic and therapeutic tools for family physicians. This article reviews anatomic landmark-guided and ultrasound-guided injections and aspiration techniques for greater trochanteric pain syndrome, the hip joint, the knee joint, the pes anserine bursa, and the iliotibial band. Indications for injections include acute and chronic inflammatory conditions, such as rheumatoid arthritis; osteoarthritis; overuse; and traumas. Joint aspirations may be performed to aid in the diagnosis of unexplained effusions and to relieve pain...

PURPOSE: Environmental sustainability in medicine is a growing concern. Determining the carbon footprint of medical procedures may aid in selecting a less impactful technique moving forward. The purpose of this study was to understand the environmental impact of different anterior cruciate ligament reconstruction techniques, for which there is no consensus in terms of optimal graft. METHODS: A life cycle analysis of different anterior cruciate ligament reconstruction techniques was performed...

Hip labral reconstruction is indicated for hypoplastic, ossified, or irreparable labral tears in the primary and revision settings. Arthroscopic reconstruction for insufficient labral tissue requires advanced surgical techniques to restore hip biomechanics and re-establish the suction seal. With the growing number of arthroscopic hip procedures being performed, this is an increasingly familiar scenario. In our experience, the iliotibial band (ITB) autograft provides a safe and effective technique for labral reconstruction at 10-year clinical follow-up...

OBJECTIVE: This study aimed to address the gap in knowledge assessing the impact of visceral and subcutaneous body fat on 3-dimensional computed tomography imaging in patients with greater trochanteric pain syndrome (GTPS) in comparison with those primarily diagnosed with osteoarthritis (OA). MATERIALS AND METHODS: We evaluated adult patients with a confirmed diagnosis of GTPS from our institutional hip-preservation clinic spanning 2011 to 2022. Selection criteria included their initial clinic visit for hip pain and a concurrent pelvis computed tomography scan...

BACKGROUND: The way in which force increases in the anterolateral tissues and the lateral extra-articular tenodesis (LET) tissue to resist internal rotation (IR) of the tibia after anterior cruciate ligament (ACL) reconstruction in isolation and after LET augmentation, respectively, is not well understood. PURPOSE: (1) To compare in a cadaveric model how force increases (ie, engages) in the anterolateral tissues with IR of the tibia after isolated ACL reconstruction and in the LET tissue after augmentation of the ACL reconstruction with LET and (2) to determine whether IR of the tibia is related to engagement of the LET tissue...

BACKGROUND: Bone-patellar tendon-bone (BTB) anterior cruciate ligament reconstruction (ACLR) is one of the conventional techniques in the revision setting especially after a primary hamstring tendon graft. The use of the iliotibial band (ITB) augmented with allograft (AG) is an encouraging graft alternative for ACLR in terms of clinical and biomechanical data in the literature. PURPOSE: To compare the clinical outcomes of BTB graft with lateral extra-articular tenodesis, modified Lemaire (BTB-LET), and an ITB graft augmented with hamstring AG (ITB-AG) in the setting of revision ACLR...
