Iliotibial Band Origin Tendinopathy Is an Underrecognized Cause of Anterolateral Hip Pain: A Narrative Review and Clinical Commentary.

ABSTRACT: Hip pain is a common concern among athletes. With gluteal tendinopathy, femoroacetabular impingement, and osteoarthritis predominating sports medicine and musculoskeletal practices, less common etiologies may be overlooked. Complex pelvic anatomy and variable pain referral patterns may make identifying an accurate diagnosis challenging. Employing a systematic approach to evaluation and having a thorough understanding of hip region anatomy are essential. A potentially overlooked cause of anterolateral hip pain is iliotibial band origin tendinopathy. Patients often present with pain around the anterolateral hip and tenderness to palpation at the anterolateral iliac crest. While patients with iliotibial band origin tendinopathy usually respond to nonsurgical intervention, there is little literature to guide evaluation and treatment, highlighting a gap in the recognition of this condition. The purpose of this narrative review is to describe the anatomy of the proximal iliotibial band origin, outline the clinical diagnosis and imaging findings of ITBOT, and summarize current treatment options.

Comparing Functional Motor Control Exercises With Therapeutic Exercise in Wrestlers With Iliotibial Band Syndrome.

CONTEXT: Iliotibial band syndrome (ITBS) is a common overuse injury in runners with parallels to our findings of overuse in Greco Roman wrestlers. Despite research indicating coordination and movement-based factors about the hip, no studies were found using functional motor control (FMC) in runners or wrestlers with ITBS. Thus, we compared FMC exercises and therapeutic exercises (TEs) on pain, function, muscle strength, and range of motion (ROM) in national-level Greco Roman wrestlers with ITBS. DESIGN: Controlled laboratory study. METHODS: Sixty national-level Greco Roman wrestlers diagnosed with ITBS were randomly assigned to 8 weeks of FMC exercises, TE, and a control group (20 individuals for each group). Pain (visual analog scale), function (triple hop test for distance, single-leg vertical jump test, and agility T test), muscle strength (handheld dynamometer), and ROM (goniometer) were measured at baseline and 8 weeks after intervention as posttest. RESULTS: Although both interventions significantly reduced pain (P < .001, η2 = .87), improved function (triple hop test P = .004, η2 = .94; single-leg vertical jump P = .002, η2 = .93; and T test P < .001, η2 = .93) and strength (hip abduction (P < .001, η2 = .52), hip external rotation (P = .02, η2 = .95), knee flexion (P ≤ .001, η2 = .94), and knee extension (P < .001, η2 = .91) compared with the control group, FMC showed more significant improvements in comparison with TE. Significant differences (P = .001) were observed between FMC and TE compared with the control group in ROM outcome. However, TE was more effective than FMC in improving ROM hip abduction (P < .001, η2 = .93), hip adduction (P = .000, η2 = .92), hip internal rotation (P < .001, η2 = .92), and hip external rotation (P < .001, η2 = .93). CONCLUSION: FMC exercises were superior to TE in terms of pain, function, and muscle strength, whereas TE was more effective for improving ROM. FMC exercise is suggested as an effective intervention for improvement of the outcomes related to ITBS in national-level Greco Roman wrestlers.

Conservative treatment of iliotibial band syndrome in runners: Are we targeting the right goals?

OBJECTIVE: Iliotibial band syndrome (ITBS) is presumably caused by excessive tension in the iliotibial band (ITB) leading to compression and inflammation of tissues lying beneath it. Usually managed conservatively, there is a lack of scientific evidence supporting the treatment recommendations, and high symptom recurrence rates cast doubt on their causal effectiveness. This review discusses the influence of common physiotherapeutic measures on risk factors contributing to tissue compression beneath the ITB. METHODS: The potential pathogenic factors are presented on the basis of a simple biomechanical model showing the forces acting on the lateral aspect of the knee. Existent literature on the most commonly prescribed physiotherapeutic interventions is critically discussed against the background of this model. Practical recommendations for the optimization of physiotherapy are derived. RESULTS: According to biomechanical considerations, ITBS may be promoted by anatomical predisposition, joint malalignments, aberrant activation of inserting muscles as well as excessive ITB stiffness. Hip abductor strengthening may correct excessive hip adduction but also increase ITB strain. Intermittent stretching interventions are unlikely to change the ITB's length or mechanical properties. Running retraining is a promising yet understudied intervention. CONCLUSIONS: High-quality research directly testing different physiotherapeutic treatment approaches in randomized controlled trials is needed.

Current Clinical Concepts: Synthesizing the Available Evidence for Improved Clinical Outcomes in Iliotibial Band Impingement Syndrome.

The current paradigm of insidious lateral knee pain involving the iliotibial band (ITB) in repetitive knee-flexion activities has been termed ITB friction syndrome since 1975. The original model for ITB pain was based on a limited or incorrect understanding of the relevant anatomy, biomechanics, and tissue science, which gradually led to a plethora of frustrating and ineffective interventional strategies. Mounting evidence from arthroscopic, cadaveric, and biomechanical studies, as well as from diagnostic imaging and histologic reports, has helped deconstruct this long-held paradigm for ITB-related pathology and treatment. By outlining the historical paradigm for our understanding of ITB pain and gathering newer evidence through extensive research, I will synthesize the available data in this clinical update to present an updated, more informed model for understanding insidious-onset ITB-related pathology and treating patients. The result is called ITB impingement syndrome.

[Clinical diagnosis and treatment for iliotibial band syndrome].

As an usually occurs in athletes, iliotibial band syndrome is payed more attention for people, the disease is diagnosed mainly by clinical symptoms, physical examination and MRI, but there is no uniform diagnostic criteria. The pathogenesis of iliotibial band syndrome is considered to be related to pressure and friction factors. As for the treatment, manipulation, muscle exercise, mainly drugs and physical therapy and so on both at home and abroad are recognized to use to achieve desired effect. For conservative failure, refractory iliotibial band syndrome patients, arthroscopy, or release of iliotibial band syndrome surgery are performed. While conservative local drug injection combined with muscle exercise could play a role in pain management besides, arthroscopic as operation method is more advanced, and applicable to all types of patients without absolute contraindication, so it is helpful for patients with early activity. At present, there is still a great deal of controversy about its pathogenesis, and there is no obvious limit for the specific indications of its various therapies in clinic, so it needs further specification.

Deep Infection Following Dry Needling in a Young Athlete: An Underreported Complication of an Increasingly Prevalent Modality: A Case Report.

CASE: Dry needling frequently is performed by a variety of practitioners for pain treatment. A 16-year-old boy had dry needling in the posterolateral aspect of the right thigh for treatment of pain after a knee injury. He developed an abscess on the posterolateral distal aspect of the right thigh deep to the site of the dry needling. Treatment included surgical drainage and intravenous antibiotics. CONCLUSION: Deep infection is a rare but serious complication of dry needling. Standardized guidelines for safety and sterile technique with dry needling are needed to minimize the risk of infection.

[Running and causes of running-related injuries].

Running is one of the most popular sports among the adult Danish population. Overuse injuries of the knee, such as runners knee, jumpers knee, patello-femoral pain syndrome and patello-femoral pre-arthrosis, are common and cause reduction of the health beneficial physical activity. Treatment should primarily focus on adjustment of training habits and physiotherapeutic guided rehabilitation. Other treatment options include changing landing pattern during running, corticosteroid injections, non-steroid anti-inflammatory drugs and ultimately surgery.

Problems With Large Joints: Knee Conditions.

As a large joint dependent on ligaments for stability and muscles and tendons for function, the knee is susceptible to a spectrum of acute and overuse injuries. Acute injuries involve the ligaments, menisci, and weight-bearing surfaces. Overuse injuries commonly affect the patellar tendon, iliotibial band, and patellofemoral complex. Acute and overuse knee injuries can be debilitating but most can be diagnosed and managed by family physicians. An appropriate history and physical examination are essential to guide diagnosis and management decisions. X-ray imaging often is required. Magnetic resonance imaging study, computed tomography scan, or ultrasonography also may be indicated to guide diagnosis and management. Knee injuries often improve with bracing, activity modification, weight loss, and physical therapy. Referral to an orthopedic subspecialist can be considered when these measures are not effective.

Radial extracorporeal shockwave therapy compared with manual therapy in runners with iliotibial band syndrome.

BACKGROUND: Although different conservative treatment options have been proposed, there is a paucity of research on the management of iliotibial band syndrome (ITBS) in runners. OBJECTIVE: To compare two treatment protocols for ITBS; radial shockwave therapy (RSWT) and manual therapy (ManT). Both therapies were administered concurrently with an exercise rehabilitation programme. METHODS: The study was designed as a randomised controlled clinical trial. Twenty-four runners with ITBS received 3 treatments at weekly intervals of either RSWT (n= 11) or ManT (n= 13). In addition, all subjects followed an exercise programme for at least 4 weeks. Main outcome measures were established as mean differences (MD) in pain during treadmill running. RESULTS: There was no significant difference in pain reduction between the two interventions at 4 weeks (p= 0.796), and 8 weeks (p= 0.155) follow-up. Thus, both groups reported similar magnitude of reduced pain during the intervention (p= 0.864). The shockwave therapy (SWT) group reported a 51% decrease in pain at week 4 (p= 0.022), and a 75% decrease at week 8 (p= 0.004). The ManT group showed a 61% reduction in pain at week 4 (p= 0.059), and a 56% reduction at week 8 (p= 0.067). CONCLUSIONS: RSWT and ManT were equally effective in reducing pain in subjects with ITBS.

Iliotibial Band Syndrome in Runners: Biomechanical Implications and Exercise Interventions.

Iliotibial band syndrome (ITBS) has known biomechanical factors with an unclear explanation based on only strength and flexibility deficits. Neuromuscular coordination has emerged as a likely reason for kinematic faults guiding research toward motor control. This article discusses ITBS in relation to muscle performance factors, fascial considerations, epidemiology, functional anatomy, strength deficits, kinematics, iliotibial strain and strain rate, and biomechanical considerations. Evidence-based exercise approaches are reviewed for ITBS, including related methods used to train the posterior hip muscles.

Deep transverse friction massage for treating lateral elbow or lateral knee tendinitis.

Background Deep transverse friction massage, one of several physical therapy interventions suggested for the management of tendinitis pain, was first demonstrated in the 1930s by Dr James Cyriax, a renowned orthopedic surgeon in England. Its goal is to prevent abnormal fibrous adhesions and abnormal scarring. This is an update of a Cochrane review first published in 2001.Objectives To assess the benefits and harms of deep transverse friction massage for treating lateral elbow or lateral knee tendinitis.Search methods We searched the following electronic databases: the specialized central registry of the Cochrane Field of Physical and Related Therapies,the Cochrane Central Register of Controlled Trials (CENTRAL),MEDLINE, EMBASE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), Clinicaltrials.gov, and the Physiotherapy Evidence Database (PEDro), up until July 2014. The reference lists of these trials were consulted for additional studies.Selection criteria All randomized controlled trials (RCTs) and controlled clinical trials (CCTs) comparing deep transverse friction massage with control or other active interventions for study participants with two eligible types of tendinitis (ie, extensor carpi radialis tendinitis (lateral elbow tendinitis, tennis elbow or lateral epicondylitis or lateralis epicondylitis humeri) and iliotibial band friction syndrome (lateral knee tendinitis)) were selected. Only studies published in English and French languages were included.Data collection and analysis Two review authors independently assessed the studies on the basis of inclusion and exclusion criteria. Results of individual trials were extracted from the included study using extraction forms prepared by two independent review authors before the review was begun.Data were cross-checked by a third review author. Risk of bias of the included studies was assessed using the "Risk of bias"tool of The Cochrane Collaboration. A pooled analysis was performed using mean difference (MD) for continuous outcomes and risk ratio (RR)for dichotomous outcomes with 95% confidence intervals (CIs).Main results Two RCTs (no new additional studies in this update) with 57 participants met the inclusion criteria. These studies demonstrated high risk of performance and detection bias, and the risk of selection, attrition, and reporting bias was unclear.The first study included 40 participants with lateral elbow tendinitis and compared (1) deep transverse friction massage combined with therapeutic ultrasound and placebo ointment (n = 11) versus therapeutic ultrasound and placebo ointment only (n = 9) and (2)deep transverse friction massage combined with phonophoresis (n = 10) versus phonophoresis only (n = 10). No statistically significant differences were reported within five weeks for mean change in pain on a 0 to 100 visual analog scale (VAS) (MD -6.60, 95%CI -28.60 to 15.40; 7% absolute improvement), grip strength measured in kilograms of force (MD 0.10, 95% CI -0.16 to 0.36) and function ona 0 to 100 VAS (MD -1.80, 95% CI -0.18.64 to 15.04; 2% improvement), pain-free function index measured as the number of painfree items (MD 1.10, 95% CI -1.00 to 3.20) and functional status (RR 3.3, 95% CI 0.4 to 24.3) for deep transverse friction massage,and therapeutic ultrasound and placebo ointment compared with therapeutic ultrasound and placebo ointment only. Likewise for deep transverse friction massage and phonophoresis compared with phonophoresis alone, no statistically significant differences were found for pain (MD -1.2, 95% CI -20.24 to 17.84; 1% improvement), grip strength (MD -0.20, 95% CI -0.46 to 0.06) and function (MD3.70, 95% CI -14.13 to 21.53; 4% improvement). In addition, the GRADE (Grades of Recommendation, Assessment, Development and Evaluation) approach was used to evaluate the quality of evidence for the pain outcome, which received a score of "very low".Pain relief of 30% or greater, quality of life, patient global assessment, adverse events, and withdrawals due to adverse events were not assessed or reported.The second study included 17 participants with iliotibial band friction syndrome (knee tendinitis) and compared deep transverse friction massage with physical therapy intervention versus physical therapy intervention alone, at two weeks. Deep transverse friction massage with physical therapy intervention showed no statistically significant differences in the three measures of pain relief on a 0 to 10 VAS when compared with physical therapy alone: daily pain (MD -0.40, 95% CI -0.80 to -0.00; absolute improvement 4%), pain while running (scale from 0 to 150) (MD -3.00, 95% CI -11.08 to 5.08), and percentage of maximum pain while running (MD -0.10, 95% CI -3.97 to 3.77). For the pain outcome, absolute improvement showed a 4% reduction in pain. However, the quality of the body of evidence received a grade of "very low."Pain relief of 30% or greater, function, quality of life, patient global assessment of success, adverse events, and withdrawals due to adverse events were not assessed or reported.Authors' conclusions We do not have sufficient evidence to determine the effects of deep transverse friction on pain, improvement in grip strength, and functional status for patients with lateral elbow tendinitis or knee tendinitis, as no evidence of clinically important benefits was found.The confidence intervals of the estimate of effects overlapped the null value for deep transverse friction massage in combination with physical therapy compared with physical therapy alone in the treatment of lateral elbow tendinitis and knee tendinitis. These conclusions are limited by the small sample size of the included randomized controlled trials. Future trials, utilizing specific methods and adequate sample sizes, are needed before conclusions can be drawn regarding the specific effects of deep transverse friction massage on lateral elbow tendinitis.

Triathlon: running injuries.

The running portion of the triathlon represents the final leg of the competition and, by some reports, the most important part in determining a triathlete's overall success. Although most triathletes spend most of their training time on cycling, running injuries are the most common injuries encountered. Common causes of running injuries include overuse, lack of rest, and activities that aggravate biomechanical predisposers of specific injuries. We discuss the running-associated injuries in the hip, knee, lower leg, ankle, and foot of the triathlete, and the causes, presentation, evaluation, and treatment of each.

Iliotibial band syndrome in runners: a systematic review.

BACKGROUND: The popularity of running is still growing and, as participation increases, the incidence of running-related injuries will also rise. Iliotibial band syndrome (ITBS) is the most common injury of the lateral side of the knee in runners, with an incidence estimated to be between 5% and 14%. In order to facilitate the evidence-based management of ITBS in runners, more needs to be learned about the aetiology, diagnosis and treatment of this injury. OBJECTIVE: This article provides a systematic review of the literature on the aetiology, diagnosis and treatment of ITBS in runners. SEARCH STRATEGY: The Cochrane Library, MEDLINE, EMBASE, CINAHL, Web of Science, and reference lists were searched for relevant articles. SELECTION CRITERIA: Systematic reviews, clinical trials or observational studies involving adult runners (>18 years) that focused on the aetiology, diagnosis and/or treatment of ITBS were included and articles not written in English, French, German or Dutch were excluded. DATA COLLECTION AND ANALYSIS: Two reviewers independently screened search results, assessed methodological quality and extracted data. The sum of all positive ratings divided by the maximum score was the percentage quality score (QS). Only studies with a QS higher than 60% were included in the analysis. The following data were extracted: study design; number and characteristics of participants; diagnostic criteria for ITBS; exposure/treatment characteristics; analyses/outcome variables of the study; and setting and theoretical perspective on ITBS. MAIN RESULTS: The studies of the aetiology of ITBS in runners provide limited or conflicting evidence and it is not clear whether hip abductor weakness has a major role in ITBS. The kinetics and kinematics of the hip, knee and/or ankle/foot appear to be considerably different in runners with ITBS to those without. The biomechanical studies involved small samples, and data seem to have been influenced by sex, height and weight of participants. Although most studies monitored the management of ITBS using clinical tests, these tests have not been validated for this patient group. While the articles were inconsistent regarding the treatment of ITBS, hip/knee coordination and running style appear to be key factors in the treatment of ITBS. Runners might also benefit from mobilization, exercises to strengthen the hip, and advice about running shoes and running surface. CONCLUSION: The methodological quality of research into the management of ITBS in runners is poor and the results are highly conflicting. Therefore, the study designs should be improved to prevent selection bias and to increase the generalizability of findings.

Iliotibial band syndrome: evaluation and management.

Iliotibial band syndrome is a common overuse injury typically seen in runners, cyclists, and military recruits. Affected patients report lateral knee pain associated with repetitive motion activities. The diagnosis is usually made based on a characteristic history and physical examination, with imaging studies reserved for cases of recalcitrant disease to rule out other pathologic entities. Several etiologies have been proposed for iliotibial band syndrome, including friction of the iliotibial band against the lateral femoral epicondyle, compression of the fat and connective tissue deep to the iliotibial band, and chronic inflammation of the iliotibial band bursa. The mainstay of treatment is nonsurgical; however, in persistent or chronic cases, surgical management is indicated.
