Background: Clinical stretching is frequently recommended for iliotibial band syndrome management. Current literature lacks conclusive findings regarding isolated human iliotibial band tissue elongation and stiffness behaviors. Applying clinical-grade stretching force results to iliotibial band tissue behavior is thus challenging.
Purpose: This study's objectives were to determine isolated iliotibial band tissue tensile behaviors during tension-to-failure testing and to relate the results to previously reported iliotibial band stretch findings.
Study Design: Descriptive in vitro laboratory study.
Methods: Ten isolated un-embalmed iliotibial band specimens were exposed to tension-to-failure testing using a 10kN material testing system. Peak load, load at yield point, and ultimate failure load were measured in Newtons. Corresponding absolute (mm) and relative (%) tissue deformation was recorded. Load-deformation curves were established to calculate iliotibial band stiffness (N/mm).
Results: A mean peak load of 872.8 ± 285.9N and resulting 9.0 ± 3.9% tissue deformation from initial length was recorded. An 805.5 ± 249.7N mean load at yield point and resulting 7.0 ± 1.9% tissue deformation was observed. A 727.6 ± 258.4N mean load was recorded directly prior to ultimate tissue failure. Mean tissue deformation at ultimate failure was 11.3 ± 4.2%. Mean iliotibial band system stiffness was 27.2 ± 4.5N/mm.
Conclusion: The iliotibial band can withstand substantial tensile forces. Clinical stretching forces likely fall within the load-deformation curve elastic region and may not result in permanent iliotibial band tissue deformation. Sustained elongation resulting from stretching the ITB may require substantial patient compliance. Future studies should investigate potential underlying factors related to positive symptom relief from iliotibial band stretching that include immunological responses, fluid accumulation, altered proprioception, and pain perception.

Repair of Acute Grade-3 Combined Posterolateral Corner Avulsion Injuries Using a Transosseous Krackow Suture Pull-Through Technique.

Background: For complete disruption of the posterolateral corner (PLC) structures, operative treatment is most commonly advocated, as nonoperative treatment has higher rates of persistent lateral laxity and posttraumatic arthritis. Some studies have shown that acute direct repair results in revision rates upwards of 37% to 40% compared with 6% to 9% for initial reconstruction. In a recent study assessing the outcomes of acute repair of PLC avulsion injuries with 2 to 7 years of follow-up, patients with adequate tissue were shown to have a much lower failure rate than previously documented.

Musculoskeletal injuries during the "Initial Training Phase" (ITP) are a major medical problem faced by law enforcement agencies worldwide. Aiming to develop an injury prevention strategy, we examined the incidence, type, associated factors, and severity of injuries and secondarily tracked their evolution over time by batches in a police academy. A retrospective cohort study was conducted using prospectively collected injury data on 979 newly recruited male police cadets enrolled in eight batches between 2015 and 2023.

Sports Medicine Center, Department of Orthopaedics, Massachusetts General Hospital, Mass General Brigham, Boston, Massachusetts.
Background: Whereas uncomplicated labral tears with preserved fibers can be effectively treated with use of labral repair techniques, complex tears and hypoplastic labra require labral reconstruction. Standard reconstruction techniques feature grafted tissue that is added to existing, deficient tissue or that is utilized to replace a hypoplastic labrum entirely. However, such approaches utilizing allografts or remote autografts are limited because they often necessitate extensive debridement of the existing labrum to prepare a site for graft implantation, an approach that can damage and devascularize the chondrolabral junction.

Context: Runners often experience acute/chronic pain due to pre-existing structural somatic dysfunction and/or acquired various overuse injuries of the lower extremity, specifically affecting the ligaments, tendons, muscles, and bones. Common structural and function dysfunctions include but are not limited to patellofemoral pain syndrome (PFPS), Achilles tendonitis, iliotibial band syndrome (ITBS), ligamentous and muscle tears, muscle sprains/strains, stress fractures, pes planus, plantar fasciitis, and shin splints.
Objectives: The purpose of this study is to assess the correlation between acute and chronic pain, overuse injuries, and observational and palpatory findings upon evaluation to establish common trends of somatic dysfunctions and determine possible etiology of the pain/injury.
Effect of Iliotibial Band Myofascial Release Combined with Valgus Correction Exercise on Pain, Range of Motion, Balance, and Quality of Life in Patients with Grade II Knee Osteoarthritis: A Randomized Clinical Trial.

The objective of this study was to find out the effect of the myofascial release technique combined with valgus correction exercise on the pain, range of motion, balance, and quality of life in participants with grade II knee osteoarthritis. Forty participants with grade II knee osteoarthritis were randomly assigned into two treatment groups in the present clinical trial; group A was the myofascial release group, and group B was the myofascial release with valgus correction exercises group. Measurement included pain, balance, range of motion, and quality of life, as measured through the visual analog scale (VAS), Berg balance scale (BBS), goniometer, and knee injury and osteoarthritis outcome score (KOOS), respectively.
