Permissive Weight-Bearing after Fixation of Displaced Acetabular Fractures: A Case Series Study

The purpose of this study was to explore the relationship between patients' self-reported and performance-based function after total hip arthroplasty (THA). Twenty-three patients (age, 61.4 ± 8.3 yrs) undergoing primary THA for hip osteoarthritis participated. Self-reported function and recovery was measured using the Hip Disability and Osteoarthritis Outcome Score activities of daily living and pain subscales. Performance-based functional measures included the timed up and go test, the stair climbing test, and the 6-minute walk test. Outcome measures were assessed preoperatively and postoperatively at 1 and 6 mos. One month after THA, performance-based function declined compared with baseline as follows: timed up and go test, -22.1% ± 25.4%; stair climbing test, -58.5% ± 63.6%; and 6-minute walk test, -22.6% ± 31.7%. In contrast, self-reported function on the Hip Disability and Osteoarthritis Outcome Score Activities of Daily Living significantly improved 1 mo after THA compared with baseline: 40.8% ± 33.3%. One to 6 mos after THA, there were significant improvements in timed up and go test, stair climbing test, and 6-minute walk test, which paralleled improvements on the Hip Disability and Osteoarthritis Outcome Score subscales, although changes were not significantly correlated. The disparity between changes in Hip Disability and Osteoarthritis Outcome Scores and functional performance postoperatively suggests that patients may overestimate their functional capacity early after THA, likely in response to pain improvements over the same time period. Therefore, outcomes assessment after THA should include both self-report and performance-based functional measures.

BackgroundThe Hip disability and Osteoarthritis Outcome Score (HOOS) is a frequently used patient-reported outcome measure (PROM) for assessment of hip disorders and treatment effects following hip surgery. The objective of the study was to translate and adapt the Hip disability and Osteoarthritis Outcome Score (HOOS) into Polish and to investigate the psychometric properties of the HOOS in patients with osteoarthritis undergoing total hip replacement (THR).Materials and methodsThe Polish version of the HOOS was developed according to current guidelines. Patients completed the HOOS, Short Form 36 Health Survey (SF-36), the visual analogue scale (VAS) for pain and the global perceived effect (GPE) scale. Psychometric properties including interpretability (floor/ceiling effects), internal consistency (Cronbach’s alpha), test-retest reliability (intra-class correlation coefficient, ICC), convergent construct validity (a priori hypothesized Spearman’s correlations between the HOOS subscales, the generic SF-36 measure and the VAS for pain) and responsiveness (effect size, association between the HOOS and GPE scores) were analyzed.ResultsThe study included 157 patients (mean age 66.8 years, 54% women). Floor effects were found prior to THR for the HOOS subscales Sports and Recreation and Quality of Life. The Cronbach’s alpha was over 0.7 for all subscales indicating satisfactory internal consistency. The test–retest reliability was good for the HOOS subscale Pain (0.82) and excellent for all other subscales with ICCs ranging from 0.91 to 0.96. The minimal detectable change ranged from 12.0 to 26.2 on an individual level and from 1.4 to 3.0 on a group level. Seven out of eight a priori hypotheses were confirmed indicating good construct validity. Responsiveness was high since the expected pattern of effect sizes in all subscales was found.ConclusionsThe Polish version of the HOOS demonstrated good reliability, validity and responsiveness for use in patient groups having THR.

Telerehabilitation is non-inferior to usual care following total hip replacement — a randomized controlled non-inferiority trial

Chilean Cross-Cultural Adaptation and Validation of the Hip Disability and Osteoarthritis Outcome Score.

Background: Total hip arthroplasty (THA) is one of the greatest successful orthopedic procedures achieved today. For patients with hip pain due to a diversity conditions, total hip arthroplasty can relieve pain, restore function, and improve quality of life. Patient education is carefully related to the early recovery process and promotes outcomes after hip replacement by supporting people to become empowered during the period of regaining. The study aimed to evaluate the effect of bundled care on self-efficacy and functional outcomes among patients undergoing total hip arthroplasty. Study design: A quasi-experimental design was used to attain this aim. Setting: This study was conducted at orthopedic surgery departments and Joint outpatient clinic at El-Demerdash Surgical Hospital, affiliated with Ain Shams University Hospitals, Cairo. Sample: A purposive sample included 78 patients. Tools of data collection: Data were collected using four tools:1- Patient’s Interview Questionnaire, 2- Hip disability and osteoarthritis outcome score scale, 3-Self- efficacy for rehabilitation outcome scale and 4-Hip Strengthening exercises performance checklist. Results: This study shows a statistically significant difference between study and control groups regarding Hip disability and osteoarthritis outcome score, self-efficacy level, and Hip Strengthening exercises performance as indicators of functional outcomes post bundled care application at p (<0.05). There was a statistically significant positive correlation between patients' total knowledge, total hip Strengthening exercises performance and patients' total Hoos in the study group post bundled care application at (P<0.001). The Conclusion: bundled care was effective care in enhancing the functional ability among patients with total hip arthroplasty. Recommendation: Apply bundled care as a care protocols for patients undergoing total hip arthroplasty and replicate the study on a larger sample selected from different geographical areas in Egypt to obtain more generalized findings in relation to current study

Can Patients Who Have Low-Grade Hip Osteoarthritis Expect the Same Outcome After Total Hip Arthroplasty Compared to Those Who Have End-Stage Osteoarthritis? – A Matched Case-Control Study

BackgroundThe aim of the study was to evaluate if physical functions usually associated with a younger population were of importance for an older population, and to construct an outcome measure for hip osteoarthritis with improved responsiveness compared to the Western Ontario McMaster osteoarthritis score (WOMAC LK 3.0).MethodsA 40 item questionnaire (hip disability and osteoarthritis outcome score, HOOS) was constructed to assess patient-relevant outcomes in five separate subscales (pain, symptoms, activity of daily living, sport and recreation function and hip related quality of life). The HOOS contains all WOMAC LK 3.0 questions in unchanged form. The HOOS was distributed to 90 patients with primary hip osteoarthritis (mean age 71.5, range 49–85, 41 females) assigned for total hip replacement for osteoarthritis preoperatively and at six months follow-up.ResultsThe HOOS met set criteria of validity and responsiveness. It was more responsive than WOMAC regarding the subscales pain (SRM 2.11 vs. 1.83) and other symptoms (SRM 1.83 vs. 1.28). The responsiveness (SRM) for the two added subscales sport and recreation and quality of life were 1.29 and 1.65, respectively. Patients ≤ 66 years of age (range 49–66) reported higher responsiveness in all five subscales than patients >66 years of age (range 67–85) (Pain SRM 2.60 vs. 1.97, other symptoms SRM 3.0 vs. 1.60, activity of daily living SRM 2.51 vs. 1.52, sport and recreation function SRM 1.53 vs. 1.21 and hip related quality of life SRM 1.95 vs. 1.57).ConclusionThe HOOS 2.0 appears to be useful for the evaluation of patient-relevant outcome after THR and is more responsive than the WOMAC LK 3.0. The added subscales sport and recreation function and hip related quality of life were highly responsive for this group of patients, with the responsiveness being highest for those younger than 66.
