Minimal clinically important change of knee flexion in people with knee osteoarthritis after non-surgical interventions using a meta-analytical approach.

Background: Minimal clinically important change (MCIC) represents the minimum patient-perceived improvement in an outcome after treatment, in an individual or within a group over time. This study aimed to determine MCIC of knee flexion in people with knee OA after non-surgical interventions using a meta-analytical approach.

Methods: Four databases (MEDLINE, Cochrane, Web of Science and CINAHL) were searched for studies of randomised clinical trials of non-surgical interventions with intervention duration of ≤ 3 months that reported change in (Δ) (mean change between baseline and immediately after the intervention) knee flexion with Δ pain or Δ function measured using tools that have established MCIC values.

ICON 2020-International Scientific Tendinopathy Symposium Consensus: the development of a core outcome set for gluteal tendinopathy.

Gluteal tendinopathy (GT) is common and can be debilitating and challenging to manage. A lack of condition specific and appropriate outcome measures compromise evidence synthesis for treatment and limits clinical guideline development. Our objective was to develop a core outcome measurement set for GT (COS-GT).

The reliability and validity of the Norwegian version of the Victorian Institute of Sports Assessment for gluteal tendinopathy questionnaire (VISA-G-Norwegian) for patients with greater trochanteric pain syndrome.

Background: Greater Trochanteric Pain Syndrome (GTPS) is a common chronic musculoskeletal condition that may affect physical function, quality of life and sleep. The Victorian Institute of Sport Assessment-Gluteal questionnaire (VISA-G) has been developed as a Patient-Reported Outcome Measurement (PROM) to address pain, everyday activities, physical activities, and difficulty with weight bearing activities. The aim of the study was to test the reliability, validity and floor and ceiling effects of the Norwegian version of the VISA-G (VISA-G-Norwegian) in a population with GTPS in a specialist health care setting.

Recommendations in the rehabilitation of patients undergoing hip abductor tendon repair: a systematic literature search and evidence based rehabilitation protocol.

Introduction: Advanced hip imaging and surgical findings have demonstrated that a common cause of greater trochanteric pain syndrome (GTPS) is hip abductor tendon (HAT) tears. Traditionally, these patients have been managed non-operatively, often with temporary pain relief. More recently, there has been an increase in published work presenting the results of surgical intervention.

Translation, validation and test-retest reliability of the VISA-G patient-reported outcome tool into Danish (VISA-G.DK).

The Victorian Institute of Sport Assessment (VISA) questionnaire model is based on item response theory using a graded response (responses reflect increasing difficulty). The purpose of the VISA-G is to monitor patient outcomes and evaluate treatment strategies for people with greater trochanteric pain syndrome (GTPS). The primary aim of the current study was to translate and culturally adapt the VISA-G into a Danish context (DK) through forward and back translation and cognitive interviews.

Responsiveness of the Victorian Institute for Sport Assessment for Gluteal Tendinopathy (VISA-G), modified Harris hip and Oxford hip scores in patients undergoing hip abductor tendon repair.

Background: A lack of consensus exists on which patient-reported outcome measures (PROMs) best evaluate change following hip abductor tendon (HAT) repair.

Objectives: To compare the responsiveness of the Victorian Institute for Sport Assessment for Gluteal Tendinopathy (VISA-G), Oxford Hip (OHS) and modified Harris Hip (mHHS) scores in patients undergoing HAT repair.

Study Design: Prospective case series.

Identification and differentiation of gluteus medius tendon pathology using ultrasound and magnetic resonance imaging.

Background: It has been suggested that imaging findings play a role in directing treatment for Greater Trochanteric Pain Syndrome. Structural diagnoses associated with Greater Trochanter Pain Syndrome include gluteal tendinosis, and partial- or full-thickness gluteal tendon tears. However, few studies have compared imaging to confirmed tendon pathology observed during surgery.

A survey of physiotherapy practice (2018) in the United Kingdom for patients with greater trochanteric pain syndrome.

Purpose: Greater Trochanteric Pain syndrome (GTPS) is a debilitating condition causing lateral hip pain. It affects up to 23.5% of women and 8% of men between 50 and 75 years old.

Effects of Altering Trunk Position during Landings on Patellar Tendon Force and Pain.

Purpose: This study aimed to verify the immediate effects of altering sagittal plane trunk position during jump landings on lower limb biomechanics, patellar tendon force, and pain of athletes with and without patellar tendinopathy.

Methods: Twenty-one elite male athletes were categorized into three groups: athletes with patellar tendinopathy (TG; n = 7), asymptomatic athletes with patellar tendon abnormalities (n = 7), and asymptomatic athletes without tendon abnormalities (CG; n = 7). A biomechanical evaluation was conducted while the athletes performed drop landings from a bench in a self-selected trunk position (SS).

Design: Cross sectional study with blinded measurers.

Participants: 38 participants with GT, 20 with end stage hip OA and 21 asymptomatic healthy control (AS) participants. All participants were women.

Gluteal Tendinopathy: Integrating Pathomechanics and Clinical Features in Its Management.

Synopsis Gluteal tendinopathy is now believed to be the primary local source of lateral hip pain, or greater trochanteric pain syndrome, previously referred to as trochanteric bursitis. This condition is prevalent, particularly among postmenopausal women, and has a considerable negative influence on quality of life. Improved prognosis and outcomes in the future for those with gluteal tendinopathy will be underpinned by advances in diagnostic testing, a clearer understanding of risk factors and comorbidities, and evidence-based management programs.

Rotator cuff tear degeneration and cell apoptosis in smokers versus nonsmokers.

Purpose: The purpose of this study was to assess the effect of smoking on supraspinatus tendon degeneration, including cellular alterations, proliferation, and apoptosis of tendon cells.

Methods: Supraspinatus tendon samples of 10 smokers and 15 nonsmokers with full-thickness tears were compared, focusing on the severity of tendon histopathology including apoptosis (programmed cell death), cellularity, and proliferation. Immunohistochemistry was used to assess the density of apoptotic cells and proliferation.

Increased substance P expression in the trochanteric bursa of patients with greater trochanteric pain syndrome.

Greater trochanteric pain syndrome (GTPS) is a pathology that can involve the trochanteric bursa or the tendons which attach to the greater trochanter. To clarify the potential importance of bursa versus tendon pathology and of substance P (SP) in contributing to pain in this condition tendon and bursa tissue biopsies were obtained from 34 patients with GTPS and 29 control subjects. Specimens were evaluated via light microscopy for histopathological and morphological differences, as well as using immunohistochemistry for macrophages (CD68), inflammatory cells (CD45) and SP.

Greater trochanteric pain syndrome negatively affects work, physical activity and quality of life: a case control study.

Musculoskeletal injury causes pain and when chronic can affect mental health, employment and quality of life. This study examined work participation, function and quality of life in people with greater trochanteric pain syndrome (GTPS, n=42), severe hip osteoarthritis (OA, n=20) and an asymptomatic group (ASC, n=23). No differences were found between the symptomatic groups on key measures, both were more affected than the ASC group, they had lower quality of life score (p<0.

Uphill running does not exacerbate collagenase-induced pathological changes in the Achilles tendon of rats selectively bred for high-capacity running.

The Achilles tendon is a frequent site for degeneration, and advanced understanding of this pathology requires an animal model that replicates the human condition. The aim of this study was to explore whether intratendinous collagenase injection combined with treadmill running created a pathology in the rat Achilles tendon consistent with human Achilles tendinosis. Collagenase was injected into one Achilles tendon of 88 high-capacity running (HCR) rats, which were randomized into treadmill running and cage control groups.

The Bonar score revisited: region of evaluation significantly influences the standardized assessment of tendon degeneration.

Objectives: Tendinopathy is a common, costly condition affecting both sporting and sedentary populations. Research into tendinopathy frequently involves the evaluation of tendinosis, a pathology characterized by a lack of inflammatory cells, collagen disruption, neovascularisation, altered cell numbers and morphology and increased glycosaminoglycans. Evaluation of these characteristics can be undertaken using the Bonar histopathology score, but the characteristics are heterogeneous throughout tendon specimens with no standardized method of determining the area to be evaluated.

Sports and exercise-related tendinopathies: a review of selected topical issues by participants of the second International Scientific Tendinopathy Symposium (ISTS) Vancouver 2012.

In September 2010, the first International Scientific Tendinopathy Symposium (ISTS) was held in Umeå, Sweden, to establish a forum for original scientific and clinical insights in this growing field of clinical research and practice. The second ISTS was organised by the same group and held in Vancouver, Canada, in September 2012. This symposium was preceded by a round-table meeting in which the participants engaged in focused discussions, resulting in the following overview of tendinopathy clinical and research issues.

Uphill treadmill running does not induce histopathological changes in the rat Achilles tendon.

Background: The purpose of this study was to investigate whether uphill treadmill running in rats created histopathological changes within the Achilles tendon consistent with Achilles tendinosis in humans.

Methods: Twenty-six mature rats selectively bred for high-capacity running were divided into run and cage control groups. Run group rats ran on a treadmill at a 15° incline for a maximum duration of 1 hr/d, 5 d/wk for 9 weeks at increasing speeds, while rats in the cage control group maintained normal cage activity.
