Return-to-work following shoulder arthroplasty in adults with osteoarthritis.

BACKGROUND: Anatomic total shoulder arthroplasty (aTSA) and hemiarthroplasty (HA) have demonstrated significant improvement in shoulder function and pain relief. Work-related outcomes have become increasingly important, while the current literature lacks evidence related to return-to-work (RTW) and which factors might have an influence on it. AIMS: This study aimed to assess RTW in patients who have received aTSA or HA at a minimum of 1-year follow-up after surgery, and secondary to evaluate possible prognostic factors associated with RTW. METHODS: We performed a retrospective query in employed patients diagnosed with primary osteoarthritis of the shoulder, who received either an aTSA or HA between February 2006 and February 2021. Preoperative and post-operative work and sports participation were assessed. RESULTS: Forty-four patients participated in this study (98% compliance), of which 40 patients (91%) were able to RTW at a median time of two (interquartile range: 2-4) months post-operatively. Patients with a medium-/high-demand occupation demonstrated RTW at a significantly lower rate (79%) than those with light-demand occupations (100%; P = 0.03). There was a statistically significant association between return to full employment and patients' expectation to fully return, absence of preoperative work adjustments and preoperative sick leave (odds ratio: 16.9 [3.1-93.5]; 18.3 [2.1-160.4]; 0.1 [0.0-0.6]). CONCLUSIONS: aTSA and HA facilitate excellent RTW rates. Patients with a medium-/high-demand occupation return at a significantly lower rate. The ability to RTW seems to be multifactorial and the results found might not be attributed to shoulder arthroplasty alone.

Does Consulting an Occupational Medicine Specialist Decrease Time to Return to Work Among Total Knee Arthroplasty Patients? A 12-Month Prospective Multicenter Cohort Study.

PURPOSE: The aim of this study is to investigate whether total knee arthroplasty (TKA) patients who consulted an occupational medicine specialist (OMS) within 3 months after surgery, return to work (RTW) earlier than patients who did not consult an OMS. METHODS: A multi-center prospective cohort study was performed among working TKA patients, aged 18 to 65 years and intending to RTW. Time to RTW was analyzed using Kaplan Meier and Mann Whitney U (MWU), and multiple linear regression analysis was used to adjust for effect modification and confounding. RESULTS: One hundred and eighty-two (182) patients were included with a median age of 59 years [IQR 54-62], including 95 women (52%). Patients who consulted an OMS were less often self-employed but did not differ on other patient and work-related characteristics. TKA patients who consulted an OMS returned to work later than those who did not (median 78 versus 62 days, MWU p < 0.01). The effect of consulting an OMS on time to RTW was modified by patients' expectations in linear regression analysis (p = 0.05). A median decrease in time of 24 days was found in TKA patients with preoperative high expectations not consulting an OMS (p = 0.03), not in patients with low expectations. CONCLUSIONS: Consulting an OMS within 3 months after surgery did not result in a decrease in time to RTW in TKA patients. TKA patients with high expectations did RTW earlier without consulting an OMS. Intervention studies on how OMSs can positively influence a timely RTW, incorporating patients' preoperative expectations, are needed.

Opening- and closing-wedge high tibial osteotomy are comparable and early full weight bearing is safe with angular stable plate fixation: a meta-analysis.

PURPOSE: The purpose of this study was to establish the gold standard for surgical technique, fixation, and rehabilitation for HTO in patients with unicompartmental knee osteoarthritis. METHODS: Medline, Embase, and SPORTDiscus databases were searched up to April 2022. Included were (1) randomized controlled trials (RCTs) comparing opening-wedge HTO (owHTO) and closing-wedge HTO (cwHTO), (2) biomechanical studies and prospective patient studies comparing biomechanical and clinical results for plate fixators, and (3) RCTs comparing an early versus delayed full-weight-bearing (FWB) protocol. RESULTS: The pooled results for the surgical technique showed no significant differences between owHTO and cwHTO for most PROMs on pain, activity, and risk for conversion to TKA. The cwHTO group showed a slightly better improvement in KOOS/WOMAC pain scores (4.51; 95% CI 1.18-7.85), and a significantly lower change in posterior tibial slope (p = 0.03). The pooled results for the fixation method showed the highest force at maximum failure for the Activmotion (Newclip Technics, France), Aescula (B. Braun Korea, Korea), 2nd generation Puddu (Arthrex Inc., USA), and TomoFix plate (Depuy Synthes, Switzerland). The pooled results for the rehabilitation protocol showed no significant differences between the early full-weight-bearing (FWB) group and the delayed FWB group for functional scores, complication rates, and delayed unions. CONCLUSION: Both owHTO and cwHTO reduced pain and improved knee function. Locking plate fixation should be used for owHTO. An early FWB protocol has proven to be safe in patients with small corrections, no hinge fractures, and non-smokers. LEVEL OF EVIDENCE: Level II.

A high physical activity level after total knee arthroplasty does not increase the risk of revision surgery during the first twelve years: A systematic review with meta-analysis and GRADE.

BACKGROUND: High physical activity (HPA) levels after total knee arthroplasty (TKA) might be related to increased wear and subsequent aseptic loosening, negatively affecting TKA survival. This systematic review studied the association between activity levels and risk of revision surgery at medium (3-10 years) and long term (>10 years) follow up in patients with TKA. METHODS: Databases (PubMed, Embase) were searched up to 12 October 2021. Studies comparing low physical activity (LPA) and HPA levels in TKA patients and related risk of revision surgery were eligible for inclusion. After data extraction and evaluation of methodological quality, a meta-analysis was performed. Quality of evidence was assessed using the GRADE framework. PROSPERO registration: CRD42020194284. RESULTS: Five cohort studies and one case-control study met the inclusion criteria, involving 4811 TKA procedures in 4263 patients (mean follow up 4-12 years). Five studies were of moderate methodological quality and one of low quality. Meta-analysis demonstrated no association between HPA level and an increased risk of all-cause revision surgery (risk ratio (RR) 0.62, 95 % confidence interval (CI) 0.24-1.63, level of certainty: very low) or revision surgery due to aseptic loosening (RR 1.33, 95 % CI 0.34-5.24, level of certainty: moderate). Only one study reported on survivorship, with an improved survivorship for the HPA group (odds ratio of 2.4, 95 % CI 1.2-4.7, level of certainty: low). CONCLUSION: During the first 12 postoperative years after TKA, there seems to be no increased risk for revision surgery for patients with a HPA level compared with patients with an LPA level.

Recovery Courses of Patients Who Return to Work by 3, 6 or 12 Months After Total Knee Arthroplasty.

Purpose This study compared the preoperative levels and postoperative recovery courses of physical and mental impairments, activity limitations and participation restrictions of working-age patients who return to work (RTW) by 3, 6 or 12 months after total knee arthroplasty (TKA). Methods A prospective survey study including TKA patients (aged < 65) (n = 146) who returned to work (RdTW) in the first postoperative year. Three groups were compared: those who returned by 3 (n = 35), 6 (n = 40) or 12 (n = 29) months. Surveys were completed preoperatively and at 6 weeks and 3, 6 and 12 months postoperatively. Outcomes represented domains of the International Classification of Functioning, i.e. physical impairments (pain, stiffness, vitality), mental impairments (mental health and depressive symptoms), activity limitations (physical functioning) and participation restrictions (social and work functioning). Results Preoperative knee-specific pain and physical functioning levels were better among patients who RdTW by 3 months, compared to those who returned by 12 months. Patients who RdTW by 3 months experienced significantly better recovery from physical impairments than those who returned by 6 months (on general pain) or 12 months (on general and knee-specific pain and on stiffness). Patients returning by 3 months experienced significantly better recovery from activity limitations (on knee-specific physical functioning). Conclusions To optimize return to work outcome after TKA surgery, the focus should lie on physical impairments (general and knee-specific pain, stiffness) and activity limitations (knee-specific physical functioning) during recovery.

Accelerometer Measured Sedentary and Physical Activity Behaviors of Working Patients after Total Knee Arthroplasty, and their Compensation Between Occupational and Leisure Time.

Purpose Objective measurements of sedentary and physical activity (PA) behavior are scarce among working-age patients who undergo total knee arthroplasty (TKA). Aim was to assess sedentary and PA behaviors using accelerometers and to identify compensation effects between occupational and leisure time of sedentary and PA behavior. Methods One year post-TKA, 51 patients wore an ActiGraph(GT3x) accelerometer for 7 days. Sedentary time, prolonged sedentary bouts (≥ 30 min) and PA (light-intensity and moderate-to-vigorous PA) were examined. Compliance with the guideline of > 150 min moderate-to-vigorous PA per week was calculated. Compensation effects were analyzed using multilevel models, splitting effects into routine and within-day compensation, stratifying by physical and non-physical jobs. The routine compensation effects are the ones of interest, representing habitual compensation during a week. Results Participants spent 60% of time in sedentary bouts and 17% in prolonged sedentary bouts, with 37% of PA spent in light-intensity and 3% in moderate-to-vigorous activity. About 70% of patients met the PA guideline. Routine compensation effects were found for workers in physical jobs, who compensated for their occupational light-intensity PA with less light-intensity PA during leisure time. Workers in non-physical jobs did not compensate for their occupational prolonged sedentary bouts, as these continued during leisure time. Conclusion This study showed that working TKA patients are highly sedentary 1 year after surgery, but most met the PA guideline. Especially those with non-physical jobs do not compensate for their occupational prolonged sedentary bouts. This stresses the need to stimulate PA among TKA patients not complying with the guidelines and those with non-physical jobs.

Work-relatedness of inguinal hernia: a systematic review including meta-analysis and GRADE.

PURPOSE: Clinicians need to know whether inguinal hernia (IH) can be attributed to work to answer questions regarding prevention and medical causation. This review describes whether work-related risk factors are associated with IH. METHODS: A systematic review was performed in Medline via PubMed until February 3rd, 2020. Inclusion criteria were that IH was diagnosed by a clinician, and workers exposed to work-related risk factors were compared to workers less exposed or not at all. A quality assessment and a meta-analysis using Cochrane's RevMan 5.3 were performed, including GRADE for quality of evidence. RESULTS: The search resulted in 540 references. Fourteen studies fulfilled the inclusion criteria, of which three were included in a meta-analysis, all three being of high quality, including 621 workers diagnosed with IH. The meta-analysis revealed significant associations with physically demanding work (OR 2.30, 95% CI 1.56-3.40). Two prospective studies, including 382 and 22,926 cases revealed associations that this was true for male workers with a lateral IH that reported standing or walking for more than six hours per workday (OR 1.45, 95% CI 1.12-1.88) or lifting cumulative loads of more than 4000 kg per workday (OR 1.32, 95% CI 1.27-1.38). The level of certainty for the latter two work-related risk factors was moderate and high according to GRADE. CONCLUSION: Lateral IH among males is associated with work-related risk factors depending on the level of exposure to the time standing/walking per workday, or the amount of load lifted per workday.

Better return to work and sports after knee arthroplasty rehabilitation?

BACKGROUND: Younger knee arthroplasty patients expect to perform better in work and sports after surgery, and often at demanding levels. Although the provision of rehabilitation is almost universal, no systematic literature review reporting the effect of these exercise-based therapies on return to work and sports is available. AIMS: To investigate the effect of exercise-based therapies on return to work and sports after knee arthroplasty. METHODS: A systematic search strategy was developed by a clinical librarian (J.G.D.), and the search was performed in Ovid Medline and EMBASE up to March 2017. In line with the PRISMA statement (Preferred Reporting Items for Systematic Reviews and Meta-Analyses), three authors (P.P.F.M.K., M.M.H. and M.H.W.F.-D.) independently screened titles and abstracts, and assessed full texts for eligibility. The inclusion criteria were patients with primary knee arthroplasty, and studies that compared at least two exercise-based rehabilitation programmes and reported outcomes including return to work or sports. No restrictions were applied for language, study design or year of publication. RESULTS: After removal of duplicates, the search resulted in 3788 studies, of which 22 were selected for full text reading. After full text reading, none of these studies reported on return to work or sports. CONCLUSIONS: No studies were found evaluating the effect of rehabilitation programmes for knee arthroplasty on return to work or sports. Given the importance of work and sports, especially for younger knee arthroplasty patients, these results underpin the importance of including return to work or sports in core outcome sets and future trials to eventually contribute to more satisfied knee arthroplasty patients.

Severe musculoskeletal time-loss injuries and symptoms of common mental disorders in professional soccer: a longitudinal analysis of 12-month follow-up data.

PURPOSE: Psychological factors have shown to be predictors of injury in professional football. However, it seems that this is a two-way relationship, as severe musculoskeletal time-loss injuries have shown to be associated with the onset of symptoms of common mental disorders (CMD). There is no longitudinal study performed exploring this interaction between symptoms of CMD and injuries. The purpose of this study was to explore the interaction between severe musculoskeletal time-loss injuries and symptoms of CMD in professional football players over a 12-month period. METHODS: Players were recruited by their national players' unions in five European countries. Symptoms of CMD included in the study were related to distress, anxiety/depression, sleep disturbance and adverse alcohol use. RESULTS: A total of 384 professional football players were enrolled in the study, of whom 262 (68%) completed the 12-month follow-up period. The mean age of the participants at baseline was 27 ± 5 years, and they had played professional football for 8 ± 5 years on average. Symptoms of CMD at baseline were not associated with the onset of severe musculoskeletal time-loss injuries during the follow-up period with relative risks (and 95% CI) ranging from 0.6 (0.3-1.0) to 1.0 (0.5-2.2). In contrast, severe musculoskeletal time-loss injuries reported at baseline were associated with the onset of symptoms of CMD during the follow-up period with relative risks ranging from 1.8 (0.8-3.7) to 6.9 (4.0-11.9). CONCLUSION: No relationship was found between symptoms of CMD and the onset of severe musculoskeletal time-loss injuries. However, professional football players who suffered from severe musculoskeletal time-loss injuries are likely to develop subsequent symptoms of CMD. This study emphasizes the need for an interdisciplinary medical approach, which not only focuses on the physical but also on the mental health of professional football players. An early identification of players at risk of symptoms of CMD, such as those suffering from severe musculoskeletal injuries, creates the opportunity for an interdisciplinary clinical medical team to treat the players timely and adequately. LEVEL OF EVIDENCE: Prospective cohort study, Level II.

Incidence of low back pain related occupational diseases in the Netherlands.

BACKGROUND: Until recently, no evidence-based criteria were available to determine the work-relatedness of low back pain (LBP) in an individual worker. Incidence figures for LBP that can be qualified as occupational disease (OD) are scarce. We studied the trend in the number of OD notifications due to LBP in the Netherlands and estimated incidence rates of LBP-related OD notifications. METHODS: We developed an instrument for the assessment of work-relatedness of non-specific LBP (NLBP) in 2004, accompanied by an OD registration guideline. We analysed the trend in LBP-related OD notifications in the register of the Netherlands Centre for Occupational Diseases (NCOD) from 2004 to 2011. We estimated incidence rates for LBP-related OD notifications with data from a prospective cohort study, performed by NCOD in 2009-2011. RESULTS: After implementation of the instrument and guideline, we noticed a huge increase in numbers of LBP-related OD-notifications, from 0.7% of all notified ODs in 2004, via 8.6% in 2005 and 13.6% in 2008, to 9.1% in 2011. We estimated the incidence rate of ODs due to LBP at 24.1 per 100,000 worker years (19.2 for NLBP), with a large difference between men and women (31.3 and 3.2, respectively). CONCLUSIONS: The instrument for the assessment of work-relatedness of NLBP played an important role in the recognition of LBP-related ODs. It provides a basis for a more uniform and objective evaluation of the role of work-related risk factors in the occurrence of NLBP. This knowledge can be used to initiate or direct preventive actions towards subgroups with higher incidence rates.

Beneficial and limiting factors affecting return to work after total knee and hip arthroplasty: a systematic review.

INTRODUCTION: A large number of patients undergoing total knee (TKA) and hip (THA) arthroplasties are of working age at the time these procedures are performed. The objective of this study was to systematically review literature on the beneficial and limiting factors affecting return to work in patients undergoing TKA or THA. METHOD: Pubmed and Embase were systematically searched to find studies that described factors that influence return to work (RTW) after surgery. The following inclusion criteria had to be met: (1) inclusion of patients with primary or revision TKA or THA; (2) description of return to work after surgery or employment status; and (3) description of a beneficial or restricting factor affecting return to work. RESULTS: Only three studies were found that fulfilled the three inclusion criteria. Three factors were discussed: (1) the mini-posterior approach compared to the two-incision approach; (2) patient movement restrictions after surgery compared to no restrictions; and (3) patient discharge based on guidelines compared to discharge without guidelines. CONCLUSIONS: This systematic review revealed that knowledge is sparse regarding beneficial or limiting factors affecting return to work after TKA or THA. Despite that, the results suggests that the two-incision approach is beneficial, patient movement restrictions are limiting, and patient discharge guidelines have no effect on the time patients take to RTW.

The effectiveness of an educational programme on occupational disease reporting.

BACKGROUND: Occupational diseases are under reported. Targeted education of occupational physicians (OPs) may improve their rate of reporting occupational diseases. AIM: To study the effectiveness of an active multifaceted workshop aimed at improving OPs' reporting of occupational diseases. METHODS: We undertook a comparative study with 112 OPs in the intervention group and 571 OPs as comparisons. The intervention was a 1-day workshop. Measurements of occupational disease reporting activity in both groups in 6-month periods before and after the intervention were collected via the national registration system. Measurements of OPs' knowledge, self-efficacy and satisfaction were made in the intervention group. Differences between the groups and predictive factors for reporting were subsequently analysed statistically. RESULTS: The percentage of reporting OPs after the intervention was significantly higher in the intervention group compared to the comparison group at 19 versus 11% (P < 0.01). No differences were found in the average number of reported occupational diseases per reporting physician after the intervention: 3.7 (SD 5.37) versus 3.4 (SD 4.56) (not significant). The self-efficacy score was a predictive factor for reporting occupational diseases (P < 0.05). Measurements of knowledge and self-efficacy increased significantly (both parameters P < 0.001) and remained after half a year. Satisfaction was high (7.85 of 10). CONCLUSIONS: An active, multifaceted workshop on occupational diseases is effective in increasing the number of physicians reporting occupational diseases. Self-efficacy measures are a predictive factor for such reporting.

Manual material handling advice and assistive devices for preventing and treating back pain in workers.

BACKGROUND: Training and assistive devices are considered major interventions to prevent back pain among workers exposed to manual material handling (MMH). OBJECTIVES: To determine the effectiveness of MMH advice and training and the provision of assistive devices in preventing and treating back pain. SEARCH STRATEGY: We searched MEDLINE to November 2005, EMBASE to August 2005, and CENTRAL, the Back Group's Trials Register, CINAHL, Nioshtic, CISdoc, Science Citation Index, and PsychLIT to September 2005. SELECTION CRITERIA: We included randomized controlled trials (RCT) and cohort studies with a concurrent control group, aimed at changing human behaviour in MMH and measuring back pain, back pain-related disability or sickness absence. DATA COLLECTION AND ANALYSIS: Two authors independently extracted the data and assessed the methodological quality using the criteria recommended by the Back Review Group for RCTs and MINORS for the cohort studies. One author of an original study supplied additional data for the review. The results and conclusions are based on the primary analysis of RCTs. We conducted a secondary analysis with cohort studies. We compared and contrasted the conclusions from the primary and secondary analyses. MAIN RESULTS: We included six RCTs (17,720 employees) and five cohort studies (772 employees). All studies focused on prevention of back pain. Two RCTs and all cohort studies met the majority of the quality criteria and were labeled high quality. We summarized the strength of the evidence with a qualitative analysis since the lack of data precluded a statistical analysis. There is moderate evidence that MMH advice and training are no more effective at preventing back pain or back pain-related disability than no intervention (four studies) or minor advice (one study). There is limited evidence that MMH advice and training are no more effective than physical exercise or back belt use in preventing back pain (three studies), and that MMH advice plus assistive devices are not more effective than MMH advice alone (one study) or no intervention (one study) in preventing back pain or related disability. The results of the cohort studies were similar to the randomised studies. AUTHORS' CONCLUSIONS: There is limited to moderate evidence that MMH advice and training with or without assistive devices do not prevent back pain, back pain-related disability or reduce sick leave when compared to no intervention or alternative interventions. There is no evidence available for the effectiveness of MMH advice and training or MMH assistive devices for treating back pain.

Prognostic factors for work ability in sicklisted employees with chronic diseases.

OBJECTIVE: Identifying prognostic factors for work ability in sicklisted employees with myocardial infarction (MI), chronic low back pain (cLBP) and major depressive disorder (MDD) in order to establish an objective basis for work ability evaluation. DESIGN: Systematic literature search in PubMed database (1 January 1990 to 1 July 2006) with the Yale prognostic research filter. Inclusion criteria were as follows: (1) work-disabled employees; (2) MI, cLBP or MDD patients; (3) longitudinal designs; and (4) return to work or compensation status as outcome measure. RESULTS: four studies on mi met the inclusion criteria and described the following prognostic factors for work ability in the acute phase of the disease and disablement: lower age; male gender; no financial basis on which to retire; lower physical job demands; fewer somatic complaints; no anxiety attacks; no diabetes; no heart failure; no atrial fibrillation; no Q waves; and a short time interval between MI and presentation at the occupational medicine clinic. Two studies on cLBP met the inclusion criteria and described the following prognostic factors for work ability after 3 months' work disablement: lower age; male gender; no treatment before sick listing; surgery in the first year of sick listing; being a breadwinner; less pain; better general health; higher job satisfaction; lower physical and/or psychological demands at work; and a higher decision latitude at work. No relevant MDD studies were found. CONCLUSION: In the earlier phases of work disablement in MI and cLBP patients, only a few studies describe disease-specific, environmental and personal prognostic factors for return to work. No studies describe prognostic factors for MDD. More evidence is needed on the topic of prognostic factors for return to work in employees with chronic diseases.
