"I feel I have been taken seriously" Women's experience of greater trochanteric pain syndrome treatment-A nested qualitative study.

BACKGROUND: Women experiencing greater trochanteric pain syndrome (GTPS) report high levels of pain and reduced quality of life. Exploring how they manage GTPS in a daily life context can provide important knowledge about individual coping strategies. Education, extracorporeal shockwave therapy (ESWT) and exercise have good group level evidence for efficacy in clinical trials and are increasingly used in routine care for patients with GTPS. Exploring women's experiences of such treatment may help understand the mechanisms underpinning these positive results and inform treatment strategies. We therefore aimed to explore how women with GTPS experience and manage their daily life, and their experience of the combined treatment of education, ESWT and exercises. METHODS: This qualitative study was nested within a cohort study based in a hospital outpatient clinic and a physiotherapy clinic in Denmark assessing the combined treatment of education, ESWT and exercises. Data was collected from eleven women using in-person, individual, semi-structured interviews which were audio recorded. Transcripts were coded and analysed using an inductive thematic analysis approach. FINDINGS: Five themes were identified: (1) Daily life was controlled and structured by pain; (2) The condition was acknowledged and taken seriously by treating professionals; (3) The participants´ experiences of the intervention-information is key; (4) Improved capability and autonomy in pain management and (5) The women´s perspectives on improving and expanding the intervention. Learning how to manage pain was experienced as the most important element of the program to the women to be able to minimize pain and manage daily life. CONCLUSION: Exploration of how women with greater trochanteric pain syndrome experienced and managed daily hip pain, and how they experienced and adapted to treatment are important novel findings that will inform clinical practice. This new knowledge may be used to inform an individualized patient education, treatment and evaluation strategy for women with the painful and debilitating condition of GTPS.

Callus formation and bone remodeling in a tibial nonunion after minimal invasive percutaneous screw fixation followed by extracorporeal shockwave therapy 17-months after initial trauma - A case report.

INTRODUCTION: The treatment of tibial nonunion is challenging and treatment may be conservative or surgical. Conservative strategies include functional braces and weight bearing, or focused extracorporeal shockwave therapy (fESWT). CASE DESCRIPTION: A 45-year-old male patient sustained spiral tibial shaft fractures and was treated surgically within 24 hours after the initial accident with intramedullary nails. The tibial fracture was later classified as nonunion after 11 months. Radiologic evaluation 17 months after the initial trauma demonstrated clinical nonunion, and subsequently the patient was offered a conservative approach with fESWT to facilitate an increase in callus formation. The handpiece was fitted with a stand-off II (long), penetration depth of 15 mm. Three cycles were administered in month 17, 19 and 20 after baseline. Each cycle consisted of three treatments sessions spaced with 6-8 days apart, and consisted of 3000 to 4000 impulses each given at 0.25-0.84 mJ/mm2. The number of impulses and the power at the focus point varied according to the pain response. OUTCOMES: The patient achieved union 23 months after fracture. A clinical important improvement was observed with both Lower Extremity Functional Scale (LEFS) (18-point difference) and Patient Specific Functional Scale (PSFS) (average: 4.7 points,) The "worst pain last 24 hours" was reduced by 5 points. These values express minimal clinically important difference (MCID) values in these functional patient-reported outcome measures. CONCLUSION: This treatment strategy may be viable in a broader setting, including private practice physiotherapy thereby treating the patient in close proximity to the patient's everyday life.

The translated Danish version of the Western Ontario Meniscal Evaluation Tool (WOMET) is reliable and responsive.

PURPOSE: The purpose of this study was to translate and cross-culturally adapt the Western Ontario Meniscal Evaluation Tool (WOMET) for use in Denmark and evaluate its test-retest reliability and comparative responsiveness. METHODS: Sixty patients (mean age 50 years (range 19-71 years), females 57%) with meniscal injury scheduled for arthroscopic meniscal surgery at a small Danish hospital in the period from September 2017 to February 2018 were included in this study. The WOMET was translated into Danish using forward and backward translation. The WOMET was completed at baseline (pre-surgery), at 3 and 6 months postoperatively. Additionally, reliability was assessed at 3 months and 3 months plus 1 week, for patients with a stable symptom state (global response question) between test and retest. Comparative responsiveness was assessed between the WOMET and the Knee Injury and Osteoarthritis Outcome Score (KOOS4-aggregate score of 4 of the 5 KOOS subscales). RESULTS: The Danish version of WOMET showed excellent test-retest reliability, intraclass correlation coefficient of 0.88 (95% CI 0.84-0.92) for the total score. The standard error of measurement was 125 points and the minimal detectable change was 347 points (i.e. 8% and 22% of the total score, respectively). The WOMET was responsive with an effect size (ES) of 1.12 at 6 months after surgery, which was comparable to the KOOS4 (ES 1.10). CONCLUSION: The Danish version of the WOMET is a reliable and responsive measure of health-related quality of life in patients with meniscal pathology. LEVEL OF EVIDENCE: Level II.

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. The second aim was to establish test-retest reliability and face validity of the VISA-G into a Danish context (DK). No major disagreements were observed between the original and translated versions of the questionnaire. A total of 58 heterogenous asymptomatic, and 49 symptomatic respondents (response rate: 92% and 78% respectively) completed the VISA-G.DK twice, 1 week apart. The VISA-G.DK had excellent internal consistency (Cronbach's alpha: asymptomatic = 0.86; symptomatic = 0.98). The test-retest reliability was excellent for the total score: ICC: 0.961 (95% CI [0.933-0.978]). Standard Error Measurement was calculated to be 0.6. Bland-Altman plots showed no significant or relevant differences from test to retest in the total score with mean differences below 1 (0.61). The minimal detectable change was 3.17 for both groups. The VISA-G.DK was found to be valid, reliable and acceptable for use in the Danish population.

Surgical fenestration and rehabilitation of a sports traumatic non-union ischial tuberosity fracture - Case report.

INTRODUCTION: Ischial tuberosity fractures and complications may be an under recognized diagnosis in adolescent athletes. Operative interventions differ and may include anchor re-fixations, resections and osteostimulating drilling and partial hamstring releases. This case report illustrates a novel and less invasive management of a non-union following a proximal ischial tuberosity avulsion. This approach has to our knowledge not previously been described. PRESENTATION OF CASE: The patient, a 14 years old female athlete, was complaining of sharp pain in the right side of the groin region, after an acute injury during a handball game. The pain was concentrated at the insertion of the adductor muscle group to the superior pubic ramus and the pubic symphysis. She was referred to our orthopaedic sports clinic after 6 months of unsuccessful conservative treatment. An MRI scan showed an ischial tuberosity non-union with a displacement less than 10 mm. Nine months after injury a surgical procedure was performed with the patient under general anaesthesia. An ultrasound guided fenestration of the non-union of the ischial tuberosity with a 1.6 mm Kirshner wire was performed. The enthesis was fenestrated 10 times, using a 1.2 mm syringe. Finally, a 5 ml local anaesthetic was injected in the area. 17 months after the trauma and 8 months postoperatively the patient had a full return to normal day activities including pain free squats and lunges. Radiologically the non-union was healed. CONCLUSION: This novel and less invasive surgical procedure may therefore be seen as a possible treatment option to non-union of the ischial tuberosity with minimal displacement.

Foot exercises and foot orthoses are more effective than knee focused exercises in individuals with patellofemoral pain.

OBJECTIVES: To examine the effect of knee targeted exercises compared to knee targeted exercises combined with foot targeted exercises and foot orthoses in patients with patellofemoral pain. DESIGN: Forty adult individuals (28 women, 12 men) diagnosed with patellofemoral pain and screened for excessive calcaneal eversion were randomized to knee targeted exercises or knee targeted exercises combined with foot targeted exercise and orthoses. METHODS: The knee targeted exercises were prescribed during three supervised consultations. Individuals were instructed to perform the exercises 3 times per week during a 12-week period. The foot targeted exercises were prescribed for 2 times per week for 12 weeks with one session per week being supervised by a physiotherapist. The primary outcome was the subscale "pain" in the Knee Injury and Osteoarthritis Outcome Score (KOOS) at 4 months. RESULTS: Individuals randomized to knee targeted exercises combined with foot targeted exercises and foot orthoses had 8.9 points (95%CI: 0.4; 17.4) - NNT=3 (2-16) larger improvement in KOOS pain at the primary endpoint. CONCLUSIONS: The addition of foot targeted exercises and foot orthoses for 12 weeks was more effective than knee targeted exercises alone in individuals with patellofemoral pain. The effect was apparent after 4 months, but not significantly different after 12 months.

Potential interaction of experimental knee pain and laterally wedged insoles for knee off-loading during walking.

BACKGROUND: Laterally wedged insoles are one of the gait modifications potentially slowing down progression of medial knee osteoarthritis. Clinical studies have, however, found large individual differences in the biomechanical effect and an insufficient pain reduction. To clarify if and how pain mediates mechanical changes during gait the current study investigated how acute experimental knee pain changes the mechanical effect of laterally wedged insoles in healthy subjects during walking. METHODS: 3D gait analysis was carried out for twelve healthy individuals. The study followed a cross-over design and data were collected with both a neutral and a 10-degree laterally wedged insole with experimental pain induced by hypertonic and isotonic saline injections into the infrapatellar fat pad. Peak knee adduction moment was the primary outcome. A repeated ANOVA (analysis of variance) was used to evaluate the relationship between the factors wedge, condition and test number. FINDINGS: Wedges significantly reduced peak knee adduction moment but experimental knee pain did only marginally affect its magnitude in either condition. While frontal plane mechanics were relatively unaffected by pain, the sagittal plane knee extension moment increased with laterally wedging (P=0.008), whereas late knee flexion moment was reduced by experimental knee pain (P=0.04). INTERPRETATION: The effect of laterally wedged insoles in attenuating knee adduction moment during walking is independent of experimental knee pain. The present study provides evidence that subjects with experimental knee pain reduce knee loading by reducing extension moment, whereas lateral wedges have the opposite effect and increase the extension moment.

Exercise therapy and custom-made insoles are effective in patients with excessive pronation and chronic foot pain--a randomized controlled trial.

BACKGROUND: Excessive foot pronation is a causal mechanisms described in relation to injuries of the lower extremities. Evidence to support an effective treatment is insufficient. OBJECTIVE: To investigate the effect of exercise and custom-made insoles to patients with excessive pronation and chronic pain conditions in the foot at short and long term follow-up. METHODS: Single blinded Randomized Controlled Trial with 80 subjects randomized: (1) Standard Intervention, (2) Insole, (3) Exercise, and (4) Insole+Exercise. Exercise - 12 week supervised program. Insoles - individually molded and posted. Pain was measured during walking, resting and running. Static and dynamic foot postures were measured as calcaneal angle, navicular drift, drop and height. RESULTS: The average duration of foot pain was 7.3 years. There was a significant pain reduction during walking within all groups at 4 and 12 months follow-up. No differences were seen between groups in any of the pain parameters. Weak correlations between changes in pain and foot postures were observed at baseline and one-year follow-up. CONCLUSION: A significant pain reduction was seen in all groups, none of the treatment modalities seem to be superior with the number of patients included. Compliance in the standard intervention group was a concern at 12 months.
