Am J Phys Med Rehabil 2011;90:681-687. This study examined the accuracy and reproducibility of a body-fixed sensor-based assessment for quantifying frontal plane angular movements of the (upper) thorax and pelvis of patients with hip osteoarthritis at different walking speeds. To evaluate accuracy, the angular movements of sensors attached to the thorax and pelvis of three patients were compared with results based on an optical motion analysis system. Accuracy was high, with small and consistent mean differences (<1.0 degree) and corresponding standard deviations (<1.3 degrees) between optical motion analysis system and body-fixed sensor data. To evaluate reproducibility, angular trunk movements were assessed twice in 15 patients. Reproducibility was high (intraclass correlation coefficients ranged from 0.86 to 0.97), and the values of the mean differences between the test and retest were small, with the 95% confidence interval containing zero. This body-fixed sensor-based assessment is an accurate and reproducible method for quantifying frontal plane compensatory trunk movements during gait of patients with hip osteoarthritis at different walking speeds
Cross-cultural adaptation of the Dutch Short Musculoskeletal Function Assessment questionnaire (SMFA-NL): Internal consistency, validity, repeatability and responsiveness
No full textThe 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
Reliability and validity of the Dutch version of the foot and ankle outcome score (FAOS)
No full textBackground: The Foot and Ankle Outcome Score (FAOS) is a patient-reported questionnaire measuring symptoms and functional limitations of the foot and ankle. Aim is to translate and culturally adapt the Dutch version of the FAOS and to investigate internal consistency, validity, repeatability and responsiveness. Methods: According to the Cross Cultural Adaptation of Self-Report Measures guideline, the FAOS was translated into Dutch. Eighty-nine patients who had undergone an ankle arthroscopy, ankle arthrodesis, ankle ligament reconstruction or hallux valgus correction completed the FAOS, FFI, WOMAC and SF-36 questionnaires and were included in the validity study. Sixty-five of them completed the FAOS a second time to determine repeatability. Responsiveness was analysed in an additional 15 patients who were being treated for foot or ankle problems. Results: Internal consistency of the FAOS is high (Cronbach's alphas varying between 0.90 and 0.96). Repeatability can be considered good, with ICC's ranging from 0.90 to 0.96. Construct validity can be classified as good with moderate-to-high correlations between the FAOS subscales and subscales of the FFI (0.55 to 0.90), WOMAC (0.57 to 0.92) and SF-36 subscales physical functioning, pain, social functioning and role-physical (0.33 to 0.81). Low standard response means were found for responsiveness (0.0 to 0.4). Conclusions: The results of this study show that the Dutch version of the FAOS is a reliable and valid questionnaire to assess symptoms and functional limitations of the foot and ankle
Patient satisfaction at and after discharge. Effect of a time lag
Full text linkObjective: Patient satisfaction is an important outcome measure for evaluating the quality of medical care. It is remarkable that consistently high satisfaction ratings have been reported over the last 30 years. There are indications that the time point of administration of a patient satisfaction questionnaire has an influence on satisfaction ratings. This study aimed at investigating whether the assessment of patient satisfaction at different time points resulted in different outcomes. Methods: Patient satisfaction was measured twice. The sample consisted of 152 orthopedic patients who filled in the questionnaire at hospital discharge and one to 12 months after discharge. Results: At follow-up, satisfaction ratings decreased significantly. Satisfaction with postoperative information decreased the most after discharge. Conclusion: The results of this study indicate that the time point of administration of a patient satisfaction questionnaire does influence satisfaction ratings. Practice implications: Patient satisfaction outcomes collected during hospitalization and after discharge may not be interpreted similarly. 9 (c) 2005 Elsevier Ireland Ltd. All rights reserved
Minimally invasive total hip and knee arthroplasty-implications for the elderly patient
No full textTotal hip arthroplasty and total knee arthroplasty have proven to be effective surgical procedures for the treatment of hip and knee osteoarthritis. In recent decades, there have been considerable efforts to improve the component designs, modes of fixation, and surgical techniques. Minimally invasive techniques are examples of these developments. Minimally invasive total joint arthroplasty aims at decreasing the surgical incision and minimizing damage to the underlying soft tissue to accelerate postoperative recovery and an earlier return to normal function. The objective here is to report on these recent developments in minimally invasive total joint arthroplasty and their implication for the elderly patient
Poorer survival after a primary implant during revision total knee arthroplasty
Full text linkRevision total knee arthroplasty (rTKA) is a complex procedure. Depending on the degree of ligament and bone damage, either primary or revision implants are used. The purpose of this study was to compare survival rates of primary implants with revision implants when used during rTKA. A retrospective comparative study was conducted between 1998 and 2009 during which 69 rTKAs were performed on 65 patients. Most common indications for revision were infection (30 %), aseptic loosening (25 %) and wear/osteolysis (25 %). During rTKA, a primary implant was used in nine knees and a revision implant in 60. Survival of primary implants was 100 % at one year, 73 % [95 % confidence interval (CI) 41-100] at two years and 44 % (95 % CI 7-81) at five years. Survival of revision implants was 95 % (95 % CI 89-100) at one year, 92 % (95 % CI 84-99) at two years and 92 % (95 % CI 84-99) at five years. Primary implants had a significantly worse survival rate than revision implants when implanted during rTKA [P = 0.039 (hazard ratio = 4.56, 95 % CI 1.08-19.27)]. Based on these results, it has to be considered whether primary implants are even an option during rTKA

No full textEffectiveness of computer-navigated minimally invasive total hip surgery compared to conventional total hip arthroplasty: design of a randomized controlled trial
No full textMinimally Invasive Total Hip Surgery ( MIS) and computer-navigated surgery were introduced several years ago. However, the literature lacks well-designed studies that provide evidence of superiority of computer-navigated MIS over a conventional THA technique. Hence, the purpose of this study is to compare ( cost) effectiveness of computer-navigated MIS with a conventional technique for THA. It is our hypothesis that computer-navigated MIS will lead to a quicker recovery during the early postoperative period ( 3 months), and to an outcome at least as good 6 months postoperatively. We also hypothesize that computer-navigated MIS leads to fewer perioperative complications and better prosthesis positioning. Furthermore, cost advantages of computer-navigated MIS over conventional THA technique are expected. Methods/design: A cluster randomized controlled trial will be executed. Patients between the ages of 18 and 75 admitted for primary cementless unilateral THA will be included. Patients will be stratified using the Charnley classification. They will be randomly allocated to have computer-navigated MIS or conventional THA technique. Measurements take place preoperatively, perioperatively, and 6 weeks and 3 and 6 months postoperatively. Degree of limping ( gait analysis), self-reported functional status and health-related quality of life ( questionnaires) will be assessed preoperatively as well as postoperatively. Perioperative complications will be registered. Radiographic evaluation of prosthesis positioning will take place 6 weeks postoperatively. An evaluation of costs within and outside the healthcare sector will focus on differences in costs between computer-navigated MIS and conventional THA technique. Discussion: Based on studies performed so far, few objective data quantifying the risks and benefits of computer-navigated MIS are available. Therefore, this study has been designed to compare ( cost) effectiveness of computer-navigated MIS with a conventional technique for THA. The results of this trial will be presented as soon as they become available
