The Dutch language anterior cruciate ligament return to sport after injury scale (ACL-RSI) - validity and reliability

The ACL-Return to Sport after Injury scale (ACL-RSI) measures athletes' emotions, confidence in performance, and risk appraisal in relation to return to sport after ACL reconstruction. Aim of this study was to study the validity and reliability of the Dutch version of the ACL-RSI (ACL-RSI (NL)). Total 150 patients, who were 3-16 months postoperative, completed the ACL-RSI(NL) and 5 other questionnaires regarding psychological readiness to return to sports, knee-specific physical functioning, kinesiophobia, and health-specific locus of control. Construct validity of the ACL-RSI(NL) was determined with factor analysis and by exploring 10 hypotheses regarding correlations between ACL-RSI(NL) and the other questionnaires. For test-retest reliability, 107 patients (5-16 months postoperative) completed the ACL-RSI(NL) again 2 weeks after the first administration. Cronbach's alpha, Intraclass Correlation Coefficient (ICC), SEM, and SDC, were calculated. Bland-Altman analysis was conducted to assess bias between test and retest. Nine hypotheses (90%) were confirmed, indicating good construct validity. The ACL-RSI(NL) showed good internal consistency (Cronbach's alpha 0.94) and test-retest reliability (ICC 0.93). SEM was 5.5 and SDC was 15. A significant bias of 3.2 points between test and retest was found. Therefore, the ACL-RSI(NL) can be used to investigate psychological factors relevant to returning to sport after ACL reconstruction

Psychological factors during rehabilitation of patients with Achilles or patellar tendinopathy:a cross-sectional study

OBJECTIVE: to examine psychological factors during rehabilitation of patients with Achilles or patellar tendinopathy as well as the association between psychological factors and tendinopathy severity, sport participation, and satisfaction with activity level and tendon function. DESIGN: cross-sectional study. SETTING: online survey platform. PARTICIPANTS: 119 patients (mean age: 44 years (SD 14)) diagnosed with Achilles or patellar tendinopathy. MAIN OUTCOME MEASURES: A range of patient-reported psychological and outcome measures were recorded. Multivariate regression analyses were performed to establish the association between each psychological factor and outcome measures, adjusted for relevant confounders. RESULTS: Psychological readiness and confidence to return to sports (I-PRRS) and pain catastrophizing (PCS) were significantly associated with tendinopathy severity (modified VISA), sport participation(OSTRC-O), and satisfaction. Kinesiophobia (TSK) and the importance to patients of returning to pre-injury activity level were significantly associated with sports participation and satisfaction. CONCLUSION: The current study provides evidence of impairments in psychological factors during rehabilitation of patients with Achilles and patellar tendinopathy. Most investigated psychological factors were associated with tendinopathy severity, function, participation, and satisfaction. Physical therapists should recognize patients with lack of psychological readiness to return to sports and also patients with kinesiophobia or catastrophizing thoughts when experiencing pain

Psychological Factors Change during the Rehabilitation of an Achilles Tendon Rupture:A Multicenter Prospective Cohort Study

OBJECTIVE: The authors sought to gain insight into the changes in psychological factors during rehabilitation after Achilles tendon rupture (ATR) and to explore the association between psychological factors during rehabilitation and functional outcome 12 months after ATR. METHODS: Fifty patients clinically diagnosed with ATR were invited to visit the hospital 3, 6, and 12 months after injury for data collection. They completed questionnaires assessing psychological factors: psychological readiness to return to sport (Injury Psychological Readiness to Return to Sport Questionnaire); kinesiophobia (Tampa Scale for Kinesiophobia); expectations, motivation, and outcome measures related to symptoms and physical activity (Achilles Tendon Total Rupture Score); and sports participation and performance (Oslo Sports Trauma Research Centre Overuse Injury Questionnaire). To determine whether psychological factors changed over time, generalized estimating equation analyses were performed. Multivariate regression analyses were used to study the association between psychological factors at 3, 6, and 12 months and outcome measures at 12 months after ATR. RESULTS: Psychological readiness to return to sport improved, and kinesiophobia decreased significantly during rehabilitation. Psychological readiness at 6 and 12 months showed significant associations with sports participation and performance. Kinesiophobia at 6 months was significantly associated with symptoms and physical activity. Motivation remained high during rehabilitation and was highly associated with symptoms and physical activity, sports participation, and performance. CONCLUSION: Psychological factors change during rehabilitation after ATR. Patients with lower motivation levels during rehabilitation, low psychological readiness to return to sports, and/or high levels of kinesiophobia at 6 months after ATR need to be identified. IMPACT: According to these results, psychological factors can affect the rehabilitation of patients with ATR. Physical therapists can play an important role in recognizing patients with low motivation levels and low psychological readiness for return to sport and patients with high levels of kinesiophobia at 6 months post-ATR. Physical therapist interventions to enhance motivation and psychological readiness to return to sport and to reduce kinesiophobia need to be developed and studied in the post-ATR population. LAY SUMMARY: With Achilles tendon rupture, level of motivation, psychological readiness for return to sport, and fear of movement can affect rehabilitation outcome. A physical therapist can help recognize these factors

Early recovery after endoscopic totally extraperitoneal (TEP) hernia repair in athletes with inguinal disruption:A prospective cohort study

Background Groin pain is a common problem in athletes which results in loss of playing time. Moreover, it can be for the cause of athletic career termination. A common cause of groin pain in athletes is inguinal disruption; pain in the groin area near the pubic tubercle were no obvious other pathology exists to explain the symptoms. Aim of this study was to evaluate the effect of endoscopic totally extraperitoneal (TEP) hernia repair in athletes with inguinal disruption. Methods Thirty-one athletes with chronic groin pain due to inguinal disruption, who had undergone conservative therapy without any effect, were included in this prospective cohort study. Prior to surgery patients were assessed by clinical examination, ultrasound of the inguinal region, x-ray and a radionuclide bone scan with single photon-emission computed tomography and CT (SPECT-CT). TEP hernia repair was performed and a lightweight polypropylene mesh was placed pre-peritoneally. Additionally the athletes' perception about their groin disability was assessed preoperatively and 6 weeks postoperatively by means of the Hip and Groin Outcome Score (HAGOS). The HAGOS consists of six subscales: Pain, Symptoms, Physical function in daily living, Physical function in Sport and Recreation, Participation in Physical Activities, and hip and/or groin-related Quality of Life. Results No complications occurred during and after surgery. After six weeks patients improved in all the separate subscales of the Hip and Groin Outcome Score (HAGOS). Within 6 weeks of surgery, 26 patients (84%) returned to sports activities with no or less groin pain. Conclusions This study showed that endoscopic totally extraperitoneal (TEP) hernia repair is an effective surgical treatment of inguinal disruption in athletes with chronic groin pain

Assessment of Prosthesis Alignment after Revision Total Knee Arthroplasty Using EOS 2D and 3D Imaging:A Reliability Study

INTRODUCTION: A new low-dose X-ray device, called EOS, has been introduced for determining lower-limb alignment in 2D and 3D. Reliability has not yet been assessed when using EOS on lower limbs containing a knee prosthesis. Therefore purpose of this study was to determine intraobserver and interobserver reliability of EOS 2D and 3D knee prosthesis alignment measurements after revision total knee arthroplasty (rTKA). METHODS: Forty anteroposterior and lateral images of 37 rTKA patients were included. Two observers independently performed measurements on these images twice. Varus/valgus angles were measured in 2D (VV2D) and 3D (VV3D). Intraclass correlation coefficients and the Bland and Altman method were used to determine reliability. T-tests were used to test potential differences. RESULTS: Intraobserver and interobserver reliability were excellent for VV2D and VV3D. No significant difference or bias between the first and second measurements or the two observers was found. A significant mean and absolute difference of respectively 1.00° and 1.61° existed between 2D and 3D measurements. CONCLUSIONS: EOS provides reliable varus/valgus measurements in 2D and 3D for the alignment of the knee joint with a knee prosthesis. However, significant differences exist between varus/valgus measurements in 2D and 3D

Cross-cultural adaptation of the Dutch Short Musculoskeletal Function Assessment questionnaire (SMFA-NL):Internal consistency, validity, repeatability and responsiveness

The purpose of this study was to translate and culturally adapt the Dutch version of the Short Musculoskeletal Function Assessment questionnaire (SMFA-NL) and to investigate the internal consistency, validity, repeatability and responsiveness of the translated version. The original SMFA was first translated and culturally adapted from English into Dutch according to a standardised procedure and subsequently tested for clinimetric quality. The study population consisted of 162 patients treated for various musculoskeletal injuries or disorders at the departments of Orthopedics and Traumatology. All respondents filled in the SMFA-NL and the SF-36 and a region-specific questionnaire. To determine repeatability, 87 respondents filled in the SMFA-NL for a second time after a time interval of three to four weeks. To determine responsiveness, 29 respondents who were treated for their injury within three months before the first assessment filled in the SMFA-NL for a second time after two to three months. The following analyses were performed to evaluate clinimetric quality of the SMFA-NL: factor analysis and Cronbach's alpha (internal consistency), floor and ceiling effects, Spearman's Rho (construct validity), intraclass correlation coefficients and the Bland & Altman method (repeatability), and standardised response means (SRM) (responsiveness). Factor analysis demonstrated four subscales of the SMFA-NL. Both the newly identified subscales of the SMFA-NL and the conventional subscales of the SMFA showed good internal consistency. No floor and some ceiling effects were found. Construct validity was good, as high correlations were found between the subscales of the SMFA-NL and the respective subscales of the SF-36 and the region-specific questionnaires. Repeatability of the SMFA-NL subscales was high, with no systematic bias between first and second assessment. Responsiveness of the SMFA-NL was moderate, as small to moderate SRMs were found. We successfully translated and culturally adapted a Dutch version of the Short Musculoskeletal Function Assessment questionnaire (SFMA-NL). This study shows that the SMFA-NL is a valid, reliable and moderately responsive method for the assessment of functional status of patients who have a broad range of musculoskeletal disorders. Furthermore, it will allow for comparison between different patient groups as well as for cross-cultural comparisons. (C) 2011 Elsevier Ltd. All rights reserved

A comprehensive multidisciplinary care pathway for hip fractures better outcome than usual care?

Introduction: Hip fracture surgery is among the most performed surgical procedures in elderly patients. Mortality rates are high, however, and patients often fail to live independently following a hip fracture. To improve outcome, multidisciplinary care pathways have been initiated, but longer-term results are lacking. Aim of this study was to compare functional outcome and living situation six months after hip fracture treatment with and without a care pathway. Patients and methods: A multicentre prospective controlled trial was conducted with three hospitals: in one hospital patients were treated with a care pathway, in the other hospitals patients received usual care. All patients aged >= 60 years witha hipfracture were asked to participate. Besides basic characteristics, health-related quality of life (EQ-5D) and performance scores of activities of daily living (Katz Index and Lawton IADL) were assessed. Differences in scores were analysed using linear regression. Propensity score adjustment was used to correct for differences between the care pathway and the usual care group. Missing data were imputed. Results: No differences in rate of return to prefracture ADL level were found between patients in the care pathway group and the usual care group. The percentage of participants in the same situation as before the fracture was the same in both treatment groups (81%). There were no significant differences in quality of life, activities of daily living or mortality (15% vs 10%, p = 0.17), but hospital stay in the care pathway group was significantly shorter (median 7 vs 10 days). Discussion: Treatment of elderly patients with a hip fracture is commonly organised in care pathways. Although short-term advantages are reported, positive effects on longer-term functional results could not be proven in our study. This study confirmed a shorter hospital stay in the care pathway group, which potentially may lead to a reduction in costs. Conclusions: Functional outcome and living situation six months after a hip fracture is the same for patients treated with or without a care pathway. (C) 2021 The Author(s).

Do CAS measurements correlate with EOS 3D alignment measurements in primary TKA?

PURPOSE: Objective of this study was to compare intraoperative computer-assisted surgery (CAS) alignment measurements during total knee arthroplasty (TKA) with pre- and postoperative coronal alignment measurements using EOS 3D reconstructions. METHODS: In a prospective study, 56 TKAs using imageless CAS were performed and coronal alignment measurements were recorded twice: before bone cuts were made and after implantation of the prosthesis. Pre- and postoperative coronal alignment measurements were performed using EOS 3D reconstructions. Thanks to the EOS radiostereography system, measurement errors due to malpositioning and deformity during acquisition are eliminated. CAS measurements were compared with EOS 3D reconstructions. Varus/valgus angle (VV), mechanical lateral distal femoral angle (mLDFA) and mechanical medial proximal tibial angle (mMPTA) were measured. RESULTS: Significantly different VV angles were measured pre- and postoperatively with CAS compared to EOS. For preoperative measurements, mLDFA did not differ significantly, but a significantly larger mMPTA in valgus was measured with CAS. CONCLUSION: Results of this study indicate that differences in alignment measurements between CAS measurements and pre- and postoperative EOS 3D are due mainly to the difference between weight-bearing and non-weight-bearing position and potential errors in validity and reliability of the CAS system. EOS 3D measurements overestimate VV angle in lower limbs with substantial mechanical axis deviation. For lower limbs with minor mechanical axis deviation as well as for mMPTA measurements, CAS measures more valgus than EOS. Eventually the results of this study are of clinical relevance, since it raises concerns regarding the validity and reliability of CAS systems in TKA. LEVEL OF EVIDENCE: IIb

MRI Assessment of Muscle Damage After the Posterolateral Versus Direct Anterior Approach for THA (Polada Trial). A Randomized Controlled Trial

BACKGROUND: There is controversy in literature whether the direct anterior approach (DAA) results in less muscle damage compared with the posterolateral approach (PLA) for total hip arthroplasty. The aim of this randomized controlled trial was to assess muscle damage between these two approaches. METHODS: Forty-six patients were included. Muscle atrophy, determined with the Goutallier classification, and muscle surface of twelve muscles were analyzed on magnetic resonance imaging images made preoperatively and one year postoperatively. Differences in component placement after DAA or PLA were assessed on radiographs. Harris hip scores and Hip disability and Osteoarthritis and Outcome Score were used as functional outcomes. RESULTS: External rotator musculature was damaged in both approaches. After PLA, the obturator muscles showed significantly more atrophy and a decrease in muscle surface. After DAA, the tensor fascia latae showed an increased muscle atrophy and the psoas muscle showed a decreased muscle surface. An increase in muscle surface was seen for the rectus femoris, sartorius, and quadratus femoris after both approaches. The muscle surface of the gluteus medius and iliacus was also increased after PLA. No difference in muscle atrophy was found between the approaches for these muscles. The inclination angle of the cup in PLA was significantly higher. No differences were found in functional outcomes. CONCLUSION: Different muscle groups were affected in the two approaches. After PLA, the external rotators were more affected, whereas the tensor fascia latae and psoas muscles were more affected after DAA

Structural Validity of the Short Musculoskeletal Function Assessment in Patients With Injuries

Background. The Short Musculoskeletal Function Assessment (SMFA) is a widely used patient-reported outcome measure, originally having 2 elements of outcome: the function index and the bother index. In multiple studies, it has been argued that the SMFA should be scored using 3, 4, or 6 subscales instead. Therefore, there is inconsistency with the number of underlying dimensions of the SMFA. Objective. The aim of this study was to evaluate the structural validity of the various proposed subscale configurations of the SMFA in a broad range of Dutch patients with injuries. Design. This study used a prospective cohort design. Methods. Participants with injuries were asked to complete the Dutch SMFA (SMFA-NL) at 5 to 8 weeks postinjury. The structural validity of the 6 different factor structures that have been proposed in other studies was evaluated using confirmatory factor analyses. Internal consistency was analyzed using Cronbach alpha. Results. A total of 491 patients participated (response rate = 74%). A 4-factor structure showed an acceptable fit (root-mean-square error of approximation [RMSEA] = 0.070, comparative fit index = 0.973, Tucker-Lewis index = 0.971). Other models, including the original 2-index structure, showed insufficient structural validity in Dutch patients with injuries. The 4-factor structure showed sufficient discriminant validity and good internal consistency (Cronbach alpha = 0.83). Limitations. It is unclear whether conclusions are generalizable across different countries, people who are elderly, and people without injuries. Conclusion. In a broad range of patients with injuries, the SMFA-NL may be best scored and interpreted using a 4-factor structure. Other factor structures showed insufficient structural validity
