Karasavvidis T, Pagan CA, Sharma AK, Jerabek SA, Mayman DJ, Vigdorchik JM. Decreased Instability in High-Risk (Hip-Spine 2B) Patients After Modifications of Surgical Planning and Technique. J Arthroplasty 2024:S0883-5403(24)00366-8. [PMID: 38642849 DOI: 10.1016/j.arth.2024.04.043] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/04/2023] [Revised: 04/08/2024] [Accepted: 04/12/2024] [Indexed: 04/22/2024] Open
Abstract
BACKGROUND Patients undergoing primary total hip arthroplasty (THA) who have spinal deformity and a stiff spine are the highest-risk group for instability. Despite the increasing use of dual-mobility cups and large femoral heads, dislocation remains a major complication after THA. Preoperative planning becomes a critical aspect of ensuring precise component positioning within a safe zone. The purpose of this study was to investigate dislocation rates over a 9-year period. METHODS A retrospective review of 4,731 THAs performed by 3 orthopaedic surgeons between January 2014 and March 2023 was performed. Spinopelvic measurements were conducted to determine the hip-spine classification group for each patient. Only patients classified as 2B (pelvic incidence-lumbar lordosis > 10° and Δsacral slope < 10°) were eligible. Both absolute and relative dislocation frequencies were then analyzed using time-series analysis techniques and Fisher's exact tests. RESULTS A total of 281 hip-spine 2B patients undergoing primary THA were eligible for analysis (57% women; mean age, range: 66 years, 23 to 87; mean body mass index, range: 28, 16 to 45). The overall dislocation rate was 4.3%. Use of femoral head sizes ≥ 40 mm increased from 4% in 2014 to 2019 to 37% in 2020 to 2023 (P < .001), while the use of dual-mobility cups decreased from 100% in 2014 to 2019 to 37% in 2020 to 2023 (P < .001). Acetabular component planning was changed from the supine plane to the standing plane in February 2020. Those changes in surgical practice were notably correlated with a significant decrease in dislocation rates from 6.8% in 2014 to 2019 to 1.5% in 2020 to 2023 (P = .03). CONCLUSIONS Our study demonstrates that the introduction of advanced preoperative THA planning to the standing plane, coupled with precise intraoperative technology for implant placement, can significantly reduce the risk of instability in high-risk THA patients. Notably, we observed a significant decrease in dislocation rates, which aligned with the shift in surgical practice. LEVEL OF EVIDENCE IV.

Effectiveness of tele-rehabilitation after total hip replacement: a systematic review and meta-analysis of randomized controlled trials. Disabil Rehabil 2023:1-6. [PMID: 37990882 DOI: 10.1080/09638288.2023.2280070] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Accepted: 11/01/2023] [Indexed: 11/23/2023]
Abstract
PURPOSE To identify articles that evaluated the efficacy of tele-rehabilitation after total hip replacement and to provide a reference for clinical decision-making and continuous improvement of rehabilitation exercise intervention strategies for clinical medical staff. METHODS Embase, PubMed, Web of Science, Medline, China National Knowledge Network and Google Scholar databases were searched for randomized controlled trials of tele-rehabilitation after total hip replacement from inception to March 4, 2023. The two researchers used the PEDro scale to assess the methodological quality of the included studies. Two researchers used the PEDro scale to assess the methodological quality of the included studies. RESULTS Ten studies with 632 participants were analysed.Compared to face-to-face rehabilitation, Internet-based telerehabilitation showed better outcomes in Get-up and go test (SMD -0.54, 95% CI -0.79 to -0.29). telerehabilitation showed no significant difference in outcomes of other functional tests and functional questionnaires. CONCLUSION In this systematic review and meta-analysis, internet-based tele-rehabilitation and face-to-face rehabilitation had the same effect on patients after total hip replacement, and compliance was higher in the tele-rehabilitation group, but attention should be devoted to standardizing this form of rehabilitation to avoid adverse events. In addition, the number and quality of included studies in this study are limited, and the outcome indicators and intervention means have not been unified. More high-quality studies are needed to verify these conclusions to better evaluate the effectiveness and advantages of telerehabilitation.Implications for rehabilitationWith the development of science and technology, remote rehabilitation technology will be applied to various fields of rehabilitation, providing personalized and extensive rehabilitation services.The application of tele-rehabilitation technology to postoperative rehabilitation after total hip arthroplasty is feasible and can reduce the workload of healthcare professionals to a certain extent.This review evaluated the randomized controlled trials of telerehabilitation after total hip arthroplasty, and the results showed that the clinical efficacy of telerehabilitation after total hip arthroplasty was not inferior to that of traditional rehabilitation.

Long-term health-related quality of life of total hip arthroplasty patients and cost-effectiveness analysis in the Japanese universal health insurance system. Jpn J Nurs Sci 2023; 20:e12537. [PMID: 37088471 DOI: 10.1111/jjns.12537] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 03/21/2023] [Accepted: 03/29/2023] [Indexed: 04/25/2023]
Abstract
AIM Total hip arthroplasty can effectively improve patients' motility with end-stage osteoarthritis. This study aimed to: (1) compare gradual changes in utility values with total hip arthroplasty and estimated values without; (2) evaluate total hip arthroplasty cost-effectiveness; and (3) evaluate cost-effectiveness by age, diagnosis, and comorbidity. METHODS Patients who underwent total hip arthroplasty between January 2008 and December 2009 were included. Patients completed the EuroQol preoperatively and at 1, 3, 5 and 7 years postoperatively. To derive the quality-adjusted life years gained, a utility score was obtained from the EuroQol item scores and combined with 7 years, and estimates were obtained by discounting the postoperative 1-year utility value at an annual rate of 2%-4%. Mixed-effects regression models were used to compare the estimated and the measured utility values. RESULTS Mean total cost was 1,921,849 yen, and quality-adjusted life years gain score was 1.746 with per cost as 1,100,715 yen. Compared with actual measurements, the estimated values from 1 to 7 years post-surgery differed significantly, and interaction was observed. Regarding age, the older the patient, the higher the cost per quality-adjusted life years. Patients with lower preoperative physical function had higher quality-adjusted life years gains, while the cost per quality-adjusted life years was lower. CONCLUSIONS Total hip arthroplasty was cost-effective. Compared with actual measurements, the estimated utility values from 1 to 7 years post-surgery significantly differed. Even among older patients and those with impaired preoperative physical functions, its cost was lower than patients' willingness to pay in Japan.

J Arthroplasty 2023:S0883-5403(23)00119-5. [PMID: 36791889 DOI: 10.1016/j.arth.2023.02.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Revised: 01/31/2023] [Accepted: 02/04/2023] [Indexed: 02/17/2023] Open
Abstract
BACKGROUND Postoperative dislocation is considered the main drawback of posterior approach total hip arthroplasty (THA). Thinner highly cross-linked polyethylene and dual-mobility bearings allow maximizing femoral head diameter per a given cup size. This study evaluated dislocation rates as large femoral head bearings were introduced into a practice over an 11-year period. METHODS A total of 1,511 consecutive primary THAs were retrospectively reviewed. Demographics, implant sizes, femoral head-acetabular cup ratio, and dislocation status were collected from the electronic medical record. Data were evaluated using time series analysis techniques as larger femoral heads, thinner polyethylene liners, and dual-mobility bearings were introduced. The cohort was 57% women with mean age and body mass index of 62 years (range, 13 to 93) and 31 kg/m2 (range, 13 to 54), respectively. RESULTS The overall dislocation rate was 0.98%. Use of femoral head sizes ≥ 40 millimeters increased from 4% in the years 2010 to 2016 to 51% in the years 2017 to 2021, correlating with a 50% reduction in dislocation rate from 1.4% to 0.7% (P = .279). Also, no dislocations occurred in patients who had dual-mobility bearings or ≥ 40-millimeter femoral heads (P = .007). Twelve of 14 dislocations occurred in cases with head-cup ratio < 0.7 (P = .013). Thirteen of 14 dislocations were in women (P = .005). CONCLUSION Maximizing the femoral head diameter per given cup size correlated with a decrease in dislocation rate in modern posterior approach THA. Furthermore, these results suggest that dual-mobility articulations should be reserved for high-risk patients or patients in whom a 40-millimeter femoral head is not possible. LEVEL OF EVIDENCE IV-consecutive case series; no control group.

Abstract
BACKGROUND Wear between the femoral head and acetabular liners continues to limit the longevity of total hip arthroplasty implants despite advances in implant materials. The purpose of this meta-analysis was to compare linear wear rates of cobalt-chromium (CoCr) and fourth-generation ceramic femoral heads on highly cross-linked polyethylene (XLPE) liners. METHODS A systematic review following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was conducted to identify all studies between 2003 and 2020 that examined in vivo wear rates of either fourth-generation ceramics or CoCr femoral heads on XLPE liners. Studies were analyzed in a weighted means analysis of wear rates and a random effects meta-analysis. RESULTS A total of 36 studies met inclusion criteria (1,657 CoCr and 659 ceramic patients). The pooled, weighted mean wear rate was 0.063 mm/year (standard deviation [SD]: 0.061, confidence interval [CI]: 0.049-0.077) for CoCr and 0.047 mm/year (SD: 0.057, CI: 0.033-0.062; P < .01) for ceramic (P < .01). A meta-analysis of 4 studies directly comparing ceramic and CoCr found that CoCr heads demonstrated 0.029 mm/year more wear than ceramic heads (95% CI: 0.026-0.059, P = .306). Mean wear for 32-mm heads was significantly higher for ceramic (P < .01), while mean wear for 36-mm heads was significantly higher for CoCr (P < .01). CONCLUSION Fourth-generation ceramic femoral heads were found to have significantly lower wear rates than CoCr heads. Unlike previous studies, this meta-analysis included only in vivo studies and those with the same generation of highly XLPE liners.

Abstract
INTRODUCTION Dislocation is amongst the most common complications following total hip arthroplasty (THA). Dual-mobility bearings have been suggested as one way to reduce the risk of dislocation, particularly among patients at increased risk. The purpose of this study was to determine the outcomes of a monoblock dual-mobility shell for patients at high risk for dislocation following primary THA. METHODS A total of 155 primary THAs with a monoblock, cementless dual-mobility acetabular component were performed in patients at high risk for dislocation. Two patients died prior to their two-year follow-up. The remaining 153 THAs were followed for a mean of 5.1 years (range: 2.1 to 9.3). RESULTS There were no dislocations; however, four patients underwent revision surgery: one for an early periprosthetic acetabular fracture, one for an early periprosthetic femoral fracture, one for a late periprosthetic femoral fracture, and one for leg-length discrepancy. Intraoperative complications included one periprosthetic acetabular fracture treated with protected weight-bearing and one intraoperative proximal femoral fracture treated with cerclage wiring. Harris Hip Scores improved from a mean of 42.4 points preoperatively to a mean of 82.4 points postoperatively (p < 0.001). No cups were radiographically loose. At a mean follow-up of 5.1 years, survivorship of the acetabular component was 99.3% (95% CI, 98.1-100%) and survivorship without any reoperation was 97.4% (95% CI, 95.9-100%). DISCUSSION Although there were no dislocations in this high-risk population, periprosthetic fractures of the femur and acetabulum were common with the implants utilised.

Tripolar Constrained and Dual Mobility Liners Are Both Successful When Cemented Into Tantalum Acetabular Revision Shells in Complex Revision Total Hip Arthroplasty. Arthroplast Today 2022; 14:53-58. [PMID: 35242957 PMCID: PMC8881686 DOI: 10.1016/j.artd.2021.12.011] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/12/2021] [Revised: 12/19/2021] [Accepted: 12/30/2021] [Indexed: 12/04/2022] Open
Abstract
Background Instability is a common complication after revision total hip arthroplasty. Tripolar constrained (TC) and dual mobility (DM) liners cemented into tantalum acetabular revision (TM) shells are established alternatives that reduce instability risk. This study compares outcomes of TC and DM liners cemented into TM shells in complex revision hip replacements. Methods Fifty cases using a TM shell and a TC or DM cemented liner with at least 12 months of follow-up were identified. There were 25 TC and 25 DM liners. Clinical, radiographic, and patient-reported outcomes were collected. Reasons for re-revision and failures were analyzed. Results The average age was 73 years in the TC group and 75 years in the DM group. The median follow-up duration was 50 months (23 - 96) and 13 months (12 – 21) for the TC and DM groups, respectively. The mean Harris Hip Score improved from 37 to 61 for the TC group and from 51 to 73 in the DM group at the last review. Two TC cases required revision for wear and liner failure. One DM insert was changed at reoperation for periprosthetic femur fracture. There were no failures of cement fixation in either group and no revisions for cup loosening. Conclusions In complex revision hip replacement with a history of instability or judged to have a high risk of instability postoperatively, TC and DM liners cemented into tantalum revision shells are both successful, giving acceptable results. The improved arc of movement with DM liners, minimizing impingement, makes them preferable except when there is a global abductor deficiency or severe joint laxity.

Abstract
BACKGROUND The benefit of total hip arthroplasty (THA) for treatment of osteoarthritis (OA) and femoral neck fractures (FNFs) in the geriatric population is well established. We compare perioperative complications and cost of THA for treatment of OA to hemiarthroplasty (HA) and THA for treatment of FNF. METHODS Data from the Centers for Medicare & Medicaid Services were used to identify all patients 65 years and older undergoing primary hip arthroplasty between 2013 and 2017. Patients were divided into 3 cohorts: THA for OA (n = 326,313), HA for FNF (n = 223,811), and THA for FNF (n = 25,995). Generalized regressions were used to compare group mortality, 90-day readmission, thromboembolic events, and 90-day episode costs, controlling for age, gender, race, and comorbidities. RESULTS Compared to patients treated for OA, FNF patients were older and had significantly more comorbidities (all P < .001). Even among the youngest age group (65-69 years) without comorbidities, FNF was associated with a greater risk of mortality at 90 days (THA-FNF odds ratio [OR] 9.3, HA-FNF OR 27.0, P < .001), 1 year (THA-FNF OR 7.8, HA-FNF OR 19.0, P < .001) and 5 years (THA-FNF hazard ratio 4.5, HA-FNF hazard ratio 10.0, P < .001). The average 90-day direct cost was $12,479 and $14,036 greater among THA and HA for FNF respectively compared to THA for OA (all P < .001). CONCLUSION Among Centers for Medicare & Medicaid Services hip arthroplasty patients, those with an FNF had significantly higher rates of mortality, thromboembolic events, readmission, and greater direct cost. Reimbursement models for arthroplasty should account for the distinctly different perioperative complication and resource utilization for FNF patients.

Abstract
BACKGROUND Total hip arthroplasty (THA) is a common and effective surgical method for advanced hip arthritis. Rehabilitation exercises are important to improve joint function after THA and are usually conducted in a home-based program. Poor patient adherence limits improvements in pain and function, affecting quality of life. The increasing use of THA in the aging Chinese population underscores the need to develop strategies that maximize functional outcomes. The purpose of this pilot study is to develop and assess the feasibility of a self-efficacy-enhancing intervention (SEEI) to improve exercise adherence in patients undergoing THA. METHODS This single-blinded, parallel, randomized control trial will recruit 150 patients after THA and randomly assign them to an intervention or control group using computer-generated block randomization. The control group will receive usual care using evidence-based guidelines. The intervention group will receive the 6-month SEEI comprising personalized exercise guidance and self-efficacy education delivered using one face-to-face education session and four telephone consultations, supplemented by written materials. Participants are encouraged to build confidence in their own abilities, set rehabilitation goals, and self-monitor their physical exercise. RESULTS Assessments will be conducted at baseline and 1, 3, and 6 months postsurgery. The outcome indicators are exercise adherence, physical function, anxiety and depression, self-efficacy of rehabilitation, joint function, and quality of life. CONCLUSIONS This study will test a theory-based intervention program to improve self-efficacy in rehabilitation, which may significantly impact out-of-hospital rehabilitation. The results will provide evidence to inform the postoperative recovery of patients undergoing THA or similar procedures.

Abstract
BACKGROUND Dual-mobility (DM) bearings reduce instability in revision total hip arthroplasty (THA); however, DM bearings are costly and reports of corrosion have recently emerged. Furthermore, no study has compared DM to standard bearings with large diameter femoral heads ≥40-mm. This study's purpose was to compare postoperative dislocation rates of standard and DM bearings with large femoral heads after revision THA. METHODS A retrospective review of 301 consecutive revision THAs was performed. The mean follow-up was 37.1 months. To isolate the effect of the double articulation, standard and DM bearings with femoral heads ≥40-mm were compared. Outcomes were postoperative dislocation and reoperation within 90 days. RESULTS The cohort consisted of 182 standard bearings and 75 DM bearings. There were no differences in revision indication comparing standard and DM bearings (P = .258). Overall dislocation rate was 8.6% (22 of 257). The dislocation rate was 5.7% for standard bearings with ≥40-mm femoral heads compared with 6.9% in DM bearings with ≥40-mm femoral heads (P = 1.000). In multivariate analysis, lower body mass index (odds ratio 1.72), female sex (odds ratio 2.01), and decreased outer femoral head diameter-to-cup component size ratio (odds ratio 1.64) were predictors of postoperative dislocation regardless of bearing type. CONCLUSION This study showed no difference in dislocation rates between standard and DM bearings when comparing similar femoral head diameters of ≥40-mm used in revision THAs. Considering the cost and potential deleterious issues associated with additional interfaces, DM bearings should be used judiciously considering similar results may be achieved with single-articulation bearings using large femoral heads.

Abstract
Iliopsoas impingement is an underdiagnosed cause of groin pain after total hip arthroplasty (THA), being responsible for 4.4% of cases. Non-surgical treatment may be effective in ∼50% of cases. Endoscopic surgery has gained popularity as an option for non-responsive patients because of its non-invasive characteristics, faster recovery and encouraging results. This study compares two different sites of endoscopic psoas tenotomy performed following THA: at the edge of the acetabulum (AR) versus at the lesser trochanter (LT). This is a retrospective review of prospectively collected data from a single-surgeon case series. Thirty-five iliopsoas tenotomy cases which had >24-month follow-up were identified. There were 21 tenotomies at the lesser trochanter. Demographic data, preop and postop pain, mHHS and NAHS scores, strength and patient satisfaction data were collected and analysed. Average age at the time of surgery was 62. Mean follow-up for the LT group was 49.11 months and 42.42 months for the AR group. Pain decreased significantly for both groups (P < 0.001). Both mHHS and NAHS showed superiority in the LT group, but this difference did not reach significance (P = 0.06). LT patients showed better strength with 71.42% of them having normal strength at latest follow-up, compared with 41.6% in the AR group. There were no complications in either group. Endoscopic tenotomy is a safe and reliable surgical option, giving significant pain relief and good functional outcomes. Tenotomy at the level of the lesser trochanter might be preferable since it shows better outcomes. Larger studies are necessary to achieve statistically significant results.

Abstract
Background Total hip arthroplasty (THA) has been used for over five decades for treating hip osteoarthritis. THA is a surgical procedure associated with prolonged hospital length of stay (LOS). The aim of this study was to analyze whether a protocol developed for fast-track THA could decrease the time taken to reach functional recovery after surgery and the hospital LOS. Blood transfusion and critical care requirements and the complication rate were evaluated as secondary endpoints. Methods Ninety-eight patients underwent THA at the University Hospital of the Federal University of Maranhão (São Luís, Brazil). The control group included 51 patients who underwent THA through the conventional method. The fast-track surgery (FTS) group included 47 patients who underwent THA through the FTS approach. The inclusion criteria were that the subjects needed to present hip osteoarthritis and at least one clinical indication for THA, and that their risk classification was in ASA category I or II. The following factors were evaluated: age, sex, diagnosis, laterality, type of arthroplasty, blood transfusion, critical care requirement, complications, LOS, and need for re-hospitalization for any reason. For spinal anesthesia, an opioid-free protocol was used. Comparison of categorical variables between the groups was performed using the chi-square test, Shapiro-Wilk test, Student t test, and Poisson regression approach. Results The FTS and control groups were similar in age and sex distribution (p > 0.05). The majority of the patients in the control group required both blood transfusion and use of the critical care unit, thus differing from the patients who underwent FTS (p < 0.001). The mean hospital LOS in the FTS group was 2.3 ± 0.8 days, compared with 6.4 ± 1.5 days in the control group (p < 0.001). Conclusion Use of FTS was associated with decreased LOS, compared with conventional THA. Trial registration https://www.researchsquare.com/article/rs-369025/v1.

Abstract
Background: This study aims to present an overview and critical appraisal of all previous studies comparing costs and outcomes of the different modes of fixation in total hip arthroplasty (THA). A secondary aim is to provide conclusions regarding the most cost-effective mode of implant fixation per gender and age-specific population in THA, based on high quality studies.Methods: A systematic search was conducted to identify cost-effectiveness analyses (CEAs) comparing different modes of implant fixation in THA. Analysis of results was done with solely CEAs that had a high methodological quality.Results: A total of 12 relevant studies were identified and presented, of which 5 were considered to have the methodological rigor for inclusion in the analysis of results. These studies found that either cemented or hybrid fixation was the most cost-effective implant fixation mode for most age- and gender-specific subgroups.Conclusion: Currently available well performed CEAs generally support the use of cemented and hybrid fixation for all age-groups relevant for THA and both genders. However, these findings were mainly based on a single database and depended on assumptions made in the studies' methodology. Issues discussed in this paper have to be considered and future work is needed.

Abstract
Background This study was done to observe the incidence of Osteo-line on the femur neck and to explore the clinical application of Osteo-line in osteotomy. Methods Eighty-nine adult femur specimens were selected to observe the incidence of Osteo-line on the femur neck. From August 2015 to January 2019, a total of 278 patients who completed unilateral hip arthroplasty at the Third Hospital of Hebei Medical University were retrospectively included. Patients who accepted osteotomy via Osteo-line on the femur neck were defined as the experimental group (n = 139), and patients who accepted osteotomy via traditional method (The femoral distance 1.5 cm above the trochanter was retained for osteotomy by visual inspection.) were defined as the control group (n = 139). According to the postoperative pelvic X-ray, Photoshop was used to evaluate the leg length discrepancy (LLD) by the CFR-T-LT method. Results Among the 89 specimens, the incidence of anterior Osteo-line was 75.28%, and the incidence of posterior Osteo-line was 100%. According to the clinical application results, the incidence of anterior Osteo-line on the femur neck was 80%, and the incidence of posterior Osteo-line was 100%. The Osteo-line was clearer than those on the femoral specimens. Twenty-six cases had LLD greater than 1 cm (9.29%), including 2 cases in the experimental group and 24 cases in the control group. The average postoperative LLD in the experimental group (0.19 ± 0.38 mm) was significantly shorter than in the control group (0.54 ± 0.51 mm)(P = 0.005). Conclusion The incidence of Osteo-line on the femur neck was high, and patients who accepted osteotomy via Osteo-line on the femur neck can achieve shorter postoperative LLD than the control group.

Abstract
BACKGROUND Total hip arthroplasty (THA) is the benchmark surgical treatment of advanced and symptomatic hip osteoarthritis. Preliminary evidence suggests that the robotic arm-assisted (RAA) technology yields more accurate and reproducible acetabular cup placement, which may improve survival rate and clinical results, but economic considerations are less well-defined. The purpose of this study was to compare the cost effectiveness of the RAA THA with manual THA (mTHA) modalities, considering direct medical costs and utilities from a payer's perspective. METHODS A Markov model was constructed to analyze two potential interventions for hip osteoarthritis and degenerative joint disorder: RAA THA and mTHA. Potential outcomes of THA were categorized into the transition states: infection, dislocation, no major complications, or revision. Cumulative costs and utilities were assessed using a cycle length of 1 year over a time horizon of 5 years. RESULTS RAA THA cohort was cost effective relative to mTHA cohort for cumulative Medicare and cumulative private payer insurance costs over the 5-year period. RAA THA cost saving had an average differential of $945 for Medicare and $1,810 for private insurance relative to mTHA while generating slightly more utility (0.04 quality-adjusted life year). The preferred treatment was sensitive to the utilities generated by successful RAA THA and mTHA. Microsimulations indicated that RAA THA was cost effective in 99.4% of cases. CONCLUSIONS In the Medicare and private payer scenarios, RAA THA is more cost effective than conventional mTHA when considering direct medical costs from a payer's perspective.

Abstract
BACKGROUND Healthcare services are facing economic constraints globally with an increasingly elderly population, and greater burdens of osteoarthritis. Because of the chronic nature of osteoarthritis and the costs associated with surgery, arthroplasty is seen as potentially cost saving. There have been no systematic reviews conducted on cost effectiveness analysis (CEA) studies of total hip arthroplasty (THA) in the management of osteoarthritis. The aim of this systematic review was to evaluate CEAs conducted on THA for osteoarthritis to determine if THA is a cost-effective intervention. MATERIALS AND METHODS A systematic review was conducted using five databases to identify all clinical CEAs of THA for osteoarthritis conducted after 1 January 1997. Twenty-eight studies were identified that met the inclusion criteria. The Quality of Health Economic Analysis (QHES) checklist was employed to assess the quality of the studies. RESULTS The average QHES score was 86 indicating high quality studies. All studies reviewed concluded that THA was a cost-effective intervention. In younger patients, cementless THA and ceramic on polyethylene implants were found to be most cost effective. Hybrid THA and metal on polyethylene implants had the greatest cost utility in older patients. In patients with acetabular defects, cemented cup with impaction bone grafting was most cost effective, while dual mobility THA was most cost effective in patients with high risk of dislocation. CONCLUSION We have shown that THA is a cost-effective treatment for hip osteoarthritis. These findings should be implemented into clinical practice to improve cost utility in health services across the world.

Abstract
BACKGROUND There is no good evidence to support the use of patient-reported outcome measures (PROMs) in setting preoperative thresholds for referral for hip and knee replacement surgery. Despite this, the practice is widespread in the NHS. OBJECTIVES/RESEARCH QUESTIONS Can clinical outcome tools be used to set thresholds for hip or knee replacement? What is the relationship between the choice of threshold and the cost-effectiveness of surgery? METHODS A systematic review identified PROMs used to assess patients undergoing hip/knee replacement. Their measurement properties were compared and supplemented by analysis of existing data sets. For each candidate score, we calculated the absolute threshold (a preoperative level above which there is no potential for improvement) and relative thresholds (preoperative levels above which individuals are less likely to improve than others). Owing to their measurement properties and the availability of data from their current widespread use in the NHS, the Oxford Knee Score (OKS) and Oxford Hip Score (OHS) were selected as the most appropriate scores to use in developing the Arthroplasty Candidacy Help Engine (ACHE) tool. The change in score and the probability of an improvement were then calculated and modelled using preoperative and postoperative OKS/OHSs and PROM scores, thereby creating the ACHE tool. Markov models were used to assess the cost-effectiveness of total hip/knee arthroplasty in the NHS for different preoperative values of OKS/OHSs over a 10-year period. The threshold values were used to model how the ACHE tool may change the number of referrals in a single UK musculoskeletal hub. A user group was established that included patients, members of the public and health-care representatives, to provide stakeholder feedback throughout the research process. RESULTS From a shortlist of four scores, the OHS and OKS were selected for the ACHE tool based on their measurement properties, calculated preoperative thresholds and cost-effectiveness data. The absolute threshold was 40 for the OHS and 41 for the OKS using the preferred improvement criterion. A range of relative thresholds were calculated based on the relationship between a patient's preoperative score and their probability of improving after surgery. For example, a preoperative OHS of 35 or an OKS of 30 translates to a 75% probability of achieving a good outcome from surgical intervention. The economic evaluation demonstrated that hip and knee arthroplasty cost of < £20,000 per quality-adjusted life-year for patients with any preoperative score below the absolute thresholds (40 for the OHS and 41 for the OKS). Arthroplasty was most cost-effective for patients with lower preoperative scores. LIMITATIONS The ACHE tool supports but does not replace the shared decision-making process required before an individual decides whether or not to undergo surgery. CONCLUSION The OHS and OKS can be used in the ACHE tool to assess an individual patient's suitability for hip/knee replacement surgery. The system enables evidence-based and informed threshold setting in accordance with local resources and policies. At a population level, both hip and knee arthroplasty are highly cost-effective right up to the absolute threshold for intervention. Our stakeholder user group felt that the ACHE tool was a useful evidence-based clinical tool to aid referrals and that it should be trialled in NHS clinical practice to establish its feasibility. FUTURE WORK Future work could include (1) a real-world study of the ACHE tool to determine its acceptability to patients and general practitioners and (2) a study of the role of the ACHE tool in supporting referral decisions.

Abstract
Pelvic motion acting as a hinge between the spine and hips is essential to maintain proper balance during bipedalism. Pelvic rotation is recruited as a compensation mechanism when spinal malalignment occurs.This pelvic rotation can affect functional acetabular orientation, and consequently functional cup positioning if a total hip arthroplasty (THA) is needed. Pelvic retroversion, frequently associated with degenerative spinal changes, implies an increase of acetabular version.Patients with flexible lumbar spines (spine users) protect the hip joint. Patients with stiff, degenerated or fused lumbar spines (hip users) demand higher hip mobility, placing the THA at risk.Pelvises in retroversion place the THA at risk for anterior dislocation when standing. In contrast, pelvises in anteversion or with low pelvic incidence (PI) can place THA at risk for posterior dislocation when sitting.Try to set the cup in an anatomic position. However, bear in mind that low PI pelvises may need more acetabular ante-inclination, and high PI pelvises more acetabular retroversion.If surgery is needed, start first by addressing the hip, except in patients with compensation (high pelvic retroversion), who may need spine surgery first to place the pelvis, and consequently the acetabulum, in a proper position.

Abstract
Background It remains uncertain if the new SuperPATH approach benefits patients in artificial hip joint replacement. We conducted a systematic review and meta-analysis of randomized controlled trials to compare the short-term outcome of SuperPATH approach and conventional approaches in hip joint replacement. Methods A systematic literature search up to April 2020 was performed to identify randomized controlled trials comparing SuperPATH with conventional approaches in hip joint replacement. We measured surgical, functional, and radiological outcomes. Mean differences or odds ratios with 95% confidence intervals were calculated and pooled using random effects models and the Hartung-Knapp-Sidik-Jonkman method. Results A total of 12 RCTs involving 726 patients met the inclusion criteria, one trial with a level I evidence, 11 trials with level II evidence. The overall meta-analysis showed that SuperPATH approach reduced incision length (MD = − 4.84, 95% CI − 7.04 to − 2.64, p < 0.01), pain VAS 7 day postoperatively (MD = − 1.39, 95% CI − 2.57 to − 0.21, p = 0.03), and HHS 7 day postoperatively (MD = 10.24, 95% CI 0.27 to 20.21, p = 0.05). The two approaches did not differ in acetabular cup positioning angles, intra- and postoperative blood loss, hospitalization period, and postoperative complications. Hip replacement via SuperPATH approach had a longer operation time than hip replacement via conventional approaches. Conclusions SuperPATH approach showed better results in decreasing incision length and early pain intensity as well as improvement of short-term functional outcome.

Abstract
In this article the authors describe a modified surgical technique developed to enhance the classical irrigation and debridement procedure to improve the possibilities of retaining a total hip arthroplasty (THA) undergoing acute periprosthetic joint infection (PJI). This technique, debridement antibiotic pearls and retention of the implant (DAPRI), aims to remove the intra-articular biofilm allowing a higher and prolonged local antibiotic concentration by using calcium sulphate antibiotic-added beads. The combination of 3 different surgical techniques (tumour-like synovectomy, Argon Beam application and chlorhexidine gluconate brushing) might enhance the disruption and removal of the bacterial biofilm which is the main responsible of antibiotics and antibodies resistance. The timing of the diagnosis (6 weeks from the original surgery or 1 week from clinical symptoms appearance in the case of an hematogenous infection) and the preoperative isolation of the germ are fundamental in order to obtain a satisfactory outcome. A 12-week course of postoperative antibiotic therapy (6 weeks I.V. and 6 weeks oral) complete the postoperative protocol used by the authors.The DAPRI technique might represent a safe and more conservative treatment for acute and early hematogenous PJI.

Abstract
BACKGROUND The changing evaluation of provider metrics and payments in total hip arthroplasty (THA) necessitates current information for leaders in advocacy and policy. This study aims to use a contemporary nationwide cohort to compare and quantify the differences between the preoperative profile and clinical outcomes of THA performed for elective indications and for femoral neck fractures. METHODS Patient records from 2007 to 2017 were queried from an administrative claims database of privately insured patients comparing THA performed for femoral neck fractures vs elective indications. Ninety-day readmission rates as well as in-hospital and 90-day postdischarge rates of local and systemic complications were collected and compared with multivariate logistic regression. RESULTS Of 83,319 primary THAs, 6895 (8.3%) were fracture cases and 76,424 (91.7%) were elective. A greater proportion of fracture patients were older, female, not obese, and had a higher burden of comorbidities (all P < .001). Fracture patients had significantly higher average lengths of stay and complication rates for all perioperative and postoperative joint and systemic complications measured (all P < .001) as well as 90-day cost (32,228 vs 22,917 USD, P < .001). CONCLUSION Fracture patients are inherently more difficult cases to manage as surgeons. The results of these data may have significance in improving care coordination and provide evidence for further risk adjustment in payment models. Leaders in advocacy and policy should consider patient-level risk adjustments within alternative payment models to account for the increased association of complications, length of stay, readmission rate, and comorbidities in fracture patients receiving THA compared to elective patients.

Abstract
Background. There is growing evidence that quality of life (QoL) has a strong association with mortality. However, incorporation of QoL is uncommon in standard survival modeling. Methods. Using data extracted from a registry of patients undergoing total knee replacement (TKR), the impact of incorporating QoL in survival modeling was explored using 4 parametric survival models. QoL was incorporated and tested in 2 forms, which are baseline and change in QoL due to intervention. Life expectancy and quality-adjusted life years (QALYs) were calculated and comparisons made to a reference model (no QoL) to translate the findings in the context of modeled economic evaluations. Results. A total of 2858 TKR cases (2309 patients) who had TKR between 2006 and 2015 were included in this analysis. Increases in baseline and change in QoL were associated with a reduction in mortality. Compared to the reference model, differences of up to 0.32 life years and 0.53 QALYs were observed, and these translated into a 9.5% change in incremental effectiveness. These differences were much larger as the strength of the association between QoL and mortality increased. Conclusions. This work has demonstrated that the inclusion of QoL measures (at baseline and change from baseline) when extrapolating survival does matter. It can influence health outcomes such as life expectancy and QALYs, which are relevant in cost-effectiveness analysis. This is important because neglecting the correlation between QoL and mortality can lead to imprecise extrapolations and thus risk misleading results affecting subsequent decisions made by policy makers.

Femoral Stress Changes after Total Hip Arthroplasty with the Ribbed Prosthesis: A Finite Element Analysis. BIOMED RESEARCH INTERNATIONAL 2020; 2020:6783936.

Abstract
Background A total hip reconstruction is related to the stress distribution throughout the prosthesis, cement, and femur. Researches on reducing the stress in all components to minimize the risk of failure are of great significance. The objective of our study was to determine the biomechanical variation in overall femoral stress and periprosthetic femoral stress distribution after implantation with the Ribbed anatomic prosthesis. Methods Three-dimensional finite element models of intact femur and Ribbed prosthesis were developed according to the morphology, while the hip joint loading and the strength of related muscles were applied in the models. The overall stress changes of the intact femur before and after the implantation were analyzed, and the periprosthetic stress distribution especially in the proximal region of the femur was quantified. Results As a result, the overall stress pattern of the femur did not change after the implantation compared with the intact femur. The region of peak stress value was located in the middle and lower segments of the full length femur, but the stress value level decreased. The final prosthesis resulted in a significant decrease in the equivalent stress level of the periprosthetic bone tissue, and the most severe area appeared at the endmost posterior quadrant. The stress shielding ratio of the Ribbed prosthesis was 71.6%. The stress value level gradually increased towards the distal part of the prosthesis and recovered to physiological level at the end of the prosthesis. Conclusions The Ribbed prosthesis can cause significant stress shielding effect in the proximal femur. These results may help optimize prosthetic design to reduce stress shielding effect and improve clinical outcomes.

Abstract
Objective To investigate the clinical efficacy and advantages of the SuperPATH minimally invasive approach to total hip arthroplasty in the treatment of femoral neck fractures in the elderly. Methods From January 2016 to September 2018, 110 cases of elderly patients with femoral neck fractures were included in the present study. According to the method of operation, the patients were divided into two groups for comparison. There were 55 cases of the SuperPATH minimally invasive approach to total hip arthroplasty and 55 cases with the conventional posterolateral approach to total hip arthroplasty. The operation time, the length of incision, the amount of operative blood loss, the hospitalization time, and the hospitalization cost were compared between the two groups. The position of total hip prosthesis was observed during the follow‐up period. All patients were evaluated for the degree of hip joint pain and the function of the hip joint using the visual analog score (VAS) and the Harris score at 1 week, 1 month, 3 months, 6 months, and 12 months after the operation. Results All patients were followed up for at least 12 months. The operation time was 108.58 ± 15.87 min in the SuperPATH group and 102.51 ± 19.61 min in the conventional group. The length of incision was 6.65 ± 1.53 cm in the SuperPATH group and 17.08 ± 1.40 cm in the conventional group. The amount of operative blood loss was 147.51 ± 28.84 mL in the SuperPATH group and 170.22 ± 25.34 mL in the conventional group. The hospitalization time was 10.05 ± 2.52 days in the SuperPATH group and 13.36 ± 3.39 days in the conventional group. The hospitalization cost was 6871.78 ± 141.63 dollars in the SuperPATH group and 7791.09 ± 184.88 dollars in the conventional group. Compared with the conventional group, the SuperPATH group had shorter incision length, less blood loss, shorter hospitalization time, and lower hospitalization cost. There was significant difference between the two groups (P < 0.05). In the two groups, there were no complications such as infection, lower extremity venous thrombosis, prosthesis loosening, periprosthetic fracture, and dislocation during the follow‐up period. The VAS score was 4.45 ± 0.94 in the SuperPATH group and 4.89 ± 0.79 in the conventional group at 1 week after the operation. There was significant difference between the two groups (P < 0.05). The Harris score was 75.36 ± 3.36 and 80.25 ± 3.09 in the SuperPATH group and 68.80 ± 3.25 and 77.35 ± 3.77 in the conventional group at 1 week and 1 month after the operation, respectively. There was significant difference between the two groups (P < 0.05). In the analysis of the operation time, the VAS score at 1 month, 3 months, 6 months, and 12 months after the operation, and the Harris score at 3 months, 6 months, and 12 months after surgery, there was no significant difference between the two groups (P > 0.05). Conclusion The SuperPATH minimally invasive approach to total hip arthroplasty is an ideal method for the treatment of femoral neck fractures in the elderly. This method has the advantages of the relatively simple operation, short incision, less blood loss, and less trauma. The patients had short hospitalization times, low hospitalization costs, and good recovery of hip joint function.

Abstract
BACKGROUND Existing evidence regarding the value of preoperative education and/or exercise (prehabilitation) for patients undergoing total joint replacement is conflicting. The purpose of this study was to conduct an updated, comprehensive systematic review with meta-analyses to determine the longitudinal effects and efficacy of prehabilitation on postoperative outcomes in patients undergoing total hip arthroplasty (THA) or total knee arthroplasty (TKA). METHODS We searched 11 electronic databases (MEDLINE, AMED, CINAHL, Embase, Scopus, ProQuest, PEDro, SportDiscus, PsycINFO, and Cochrane) from their inception to May 2016 for randomized controlled trials that compared changes in pain, function, strength, anxiety, and hospital length of stay following THA or TKA. Two reviewers independently determined study eligibility, rated study quality, and extracted data. There were no restrictions on study dates, patient characteristics, or the follow-up time point at which postoperative outcomes were measured. We excluded trials comparing 2 interventions. Methodological quality assessments were performed using the Cochrane risk-of-bias tool. We calculated pooled estimates, with 95% confidence intervals (CIs), of standardized mean differences (SMDs). RESULTS Thirty-five studies with 2,956 patients were included. After a preoperative program, patients undergoing THA, but not TKA, had significantly less postoperative pain than controls (SMD = 0.15, 95% CI = 0.03 to 0.27, p = 0.017). Postoperative function was also significantly improved compared with controls, with similar improvement after THA (SMD = 0.32, 95% CI = 0.15 to 0.50, p < 0.001) and TKA (SMD = 0.32, 95% CI = 0.06 to 0.57, p = 0.015). Significantly greater quadriceps strength was observed after TKA (SMD = 0.42, 95% CI = 0.16 to 0.68, p = 0.002). No significant differences in hamstring strength were observed between groups after TKA (p = 0.132). Small-to-moderate but nonsignificant improvements in anxiety (SMD = 0.17, 95% CI = -0.05 to 0.39; p = 0.128) were observed after THA, and length of stay was significantly shorter after TKA (SMD = 0.54, 95% CI = 0.24 to 0.84, p < 0.001) and THA (p = 0.027). CONCLUSIONS Overall effect sizes for prehabilitation were small to moderate. In patients undergoing TKA, significant improvements were observed in function, quadriceps strength, and length of stay. In patients undergoing THA, significant improvements were observed in pain, function, and length of stay. Included studies were inconsistent with regard to the types of outcome measures reported, and the quality of the interventions varied. A more standardized approach to reporting of clinical trial interventions and patient compliance is needed to thoroughly evaluate the effects of prehabilitation on postoperative outcomes.

Abstract
BACKGROUND One of the least studied areas in orthopaedics is total joint arthroplasty (TJA) in pediatric patients. Recent studies have confirmed that these procedures are being performed on pediatric patients, making it critical to understand the rates of surgical complications in this patient population. We sought to examine the frequency in which surgical complications occur in pediatric patients, aged 20 and younger, undergoing TJA compared with adults. METHODS Data from the 2003 to 2012 Kids' Inpatient Database (ages 20 and younger) and 2002 to 2013 National Inpatient Sample (ages 21 and over) were analyzed. Pediatric patients were matched to 3 adult controls (1 per age group: 21 to 50, 51 to 65, and over 65 y) using patient characteristics including sex, race, orthopaedic diagnosis, and preoperative loss of function. Comparisons were then made between the rates and relative risks (RRs) of surgical complications between pediatric and adult patients. Finally, we examined patient factors associated with surgical complications, utilizing modified Poisson regression models with robust SEs. RESULTS Three adult controls (ie, 1 control from each age group) were identified for 1385 pediatric patients, for a total sample of 5540 TJA patients. Approximately 10% of pediatric patients experienced either major or minor surgical complications. The overall rate of major complications in pediatric patients was 5.05%, compared with 4.79% in adult controls [RR: 1.06 (0.81 to 1.38), P=0.69]. The overall rate of minor complications in pediatric patients was 5.78%, compared with 5.68% in adult controls [RR: 1.02 (0.80 to 1.30), P=0.78]. When adjusted for patient demographics, the RR of major complications was 49% higher in pediatric patients compared with ages 21 to 50 [RR: 1.49 (1.03 to 2.16), P=0.03] with no statistically significant differences noted for other age groups. For minor complications, the adjusted RR in pediatric patients, compared with any other age group, did not approach statistical significance. CONCLUSIONS Pediatric patients undergoing TJA experience major and minor surgical complications at rates comparable with their adult counterparts. Our findings offer important insight on the rates of surgical complications in pediatric TJA patients, which is valuable for preoperative education and consultation with patients and families.

Abstract
Consecutive milestones in hip arthroplasty design and surgical technique have contributed to the successful and cost-effective intervention this procedure has become today in maintaining mobility and quality of life in patients with osteoarthritis, fracture, or other hip conditions. With the increasing prevalence of hip joint replacements, the need for improved diagnostic imaging tools to guide revision surgery has risen in parallel. Over the last few years, promising data have emerged on the potential role of bone SPECT/CT imaging in the assessment of patients with recurrent pain after arthroplasty. This review summarizes the trends in hip arthroplasty surgery (partial vs total arthroplasty; cemented vs cementless arthroplasty; resurfacing arthroplasty) and prosthesis design (bearing materials; stem designs) over the last decade. In particular, the impact on the biomechanics and interpretation of bone SPECT/CT findings is discussed, with emphasis on integrative reporting in the following frequently encountered conditions: lysis/aseptic loosening, septic loosening, heterotopic ossification, periprosthetic fracture, tendinopathies, and adverse local tissue reactions. Based on the available literature data, bone SPECT/CT is increasingly being used as second-line imaging modality when conventional investigations are nondiagnostic. Further outcome research is warranted to examine whether this technique could be used earlier in patient management.

Abstract
BACKGROUND Dislocation is one of the most common complications after revision THA. Dual-mobility constructs and large femoral heads (ie, 40 mm) are two contemporary, nonconstrained bearing options used in revision THA to minimize the risk of dislocation; however, it is not currently established if there is a clear benefit to using dual-mobility constructs over large femoral heads in the revision setting. QUESTIONS/PURPOSES We sought to determine if dual-mobility constructs would provide a reduction in dislocation, rerevision for dislocation, and reoperation or other complications as compared with large femoral heads in revision THA. METHODS From 2011 to 2014, a series of 355 THAs underwent revision for any reason and received either a dual-mobility construct (146 THAs) or a 40-mm large femoral head (209 THAs). Indications for either construct were based on surgeon judgment; however, there is a preference to use dual-mobility constructs in patients believed to be at higher risk of dislocation. In the dual-mobility group, 20 of 146 (14%) were excluded because of loss of followup before 2 years or because they had a dual-mobility shell cemented into a preexisting acetabular component. In the large head group, 33 of 209 (16%) were lost to followup before 2 years. Followup in the dual-mobility group was 3.3 ± 0.8 years and followup in the large head group was 3.9 ± 0.9 years. Primary endpoints included dislocation, rerevisions for dislocation, and reoperations, which were determined through our institution's total joint registry and verified by individual patient chart review. Age and body mass index were not different with the numbers available between the groups, but there was a slight predominance of females in the dual-mobility group (52% [66 of 126] female) versus the 40-mm large head group (41% [72 of 176] female) (p = 0.05). Notably, 33% (41 of 126) of patients receiving the dual-mobility constructs had the index revision THA done for a diagnosis of recurrent dislocation versus 9% (17 of 176) in the 40-mm large head group. Mean effective head size in the dual-mobility group was 47 mm (range, 38-58 mm). RESULTS The subsequent frequency of dislocation in the dual-mobility construct group was less (3% [four of 126] dual-mobility versus 10% [17 of 176] in the 40-mm large head group; hazard ratio, 3.2 [1.1-9.4]; p = 0.03). Rerevision for dislocation in the dual-mobility construct group was less frequent (1% [one of 126] dual-mobility versus 6% [10 of 176] in the 40-mm large head group; hazard ratio, 7.1 [0.9-55.6]; p = 0.03). Reoperation for any cause in the dual-mobility construct group was less frequent (6% [eight of 126] dual-mobility versus 15% [27 of 176] in the 40-mm large head group; hazard ratio, 2.5 [1.1-5.5]; p = 0.02); there were no differences between the groups in terms of the overall percentage of complications in each group. CONCLUSIONS When compared with patients treated with a 40-mm large femoral head, patients undergoing revision THA who received a dual-mobility construct had a lower risk of subsequent dislocation, rerevision for dislocation, and reoperation for any reason in the first several years postoperatively. Those findings were present despite selection bias in this study to use the dual-mobility construct in patients at the highest risk for subsequent dislocation. Given the lower risk of subsequent dislocation, rerevision, and reoperation with the dual-mobility construct, some surgeons may wish to consider whether the role of dual-mobility should be judiciously expanded in contemporary revision THA.

Abstract
Cost-effectiveness evaluations concerning devices for total knee arthroplasty (TKA) have little impact on real-life management of these devices. This study explored how pharmacoeconomic models can inform the procurement of TKA devices to improve their value for money. Our study included three phases: i) literature search for data of outcome, cost, and device type in TKA; ii) development of a Markov model predicting costs, QALYs, and net monetary benefit (NMB); iii) simulation of tenders aimed at value-based device procurement. Phases 1 and 2 were managed by selecting a single study as the source of data for our analysis. In Phase 3, each TKA device was associated with its values of NMB, and the tender scores were estimated. Finally, the ranking of each device in the simulated tender was determined. We identified a study published in 2016 as our source of data. Five devices were evaluated. For these devices, QALYs were 7.3952, 7.2939, 7.4952, 7.1919, 7.2930; NMB: £142,005, £140,653, £144,184, £138,040, £140,261; tender scores: 64.53, 42.53, 100, 0, 36.15, respectively. We showed that incorporating the principles of cost-effectiveness into the tendering process is feasible for TKA devices. This can maximize the value for money for these devices.

Abstract
Metals and metal alloys are the most used materials in orthopedic implants. The focus is on total hip arthroplasty (THA) that, though well tolerated, may be associated with local and remote adverse effects in the medium-long term. This review aims to summarize data on the biological consequences of the metal implant degradation that have been attributed predominantly to metal-on-metal (MoM) THA. Local responses to metals consist of a broad clinical spectrum ranging from small asymptomatic tissue lesions to severe destruction of bone and soft tissues, which are designated as metallosis, adverse reactions to metal debris (ARMD), aseptic lymphocytic vasculitis associated lesion (ALVAL), and pseudotumors. In addition, the dissemination of metal particles and ions throughout the body has been associated with systemic adverse effects, including organ toxicity, cancerogenesis, teratogenicity, and immunotoxicity. As proved by the multitude of studies in this field, metal degradation may increase safety issues associated with THA, especially with MoM hip systems. Data collection regarding local, systemic and long-term effects plays an essential role to better define any safety risks and to generate scientifically based recommendations.

The Impact of Discharge Disposition on Episode-of-Care Reimbursement After Primary Total Hip Arthroplasty. J Arthroplasty 2017; 32:2969-2973. [PMID: 28601245 PMCID: PMC6383651 DOI: 10.1016/j.arth.2017.04.062] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/02/2017] [Revised: 04/24/2017] [Accepted: 04/26/2017] [Indexed: 02/08/2023] Open
Abstract
BACKGROUND Total joint arthroplasty (TJA) accounts for more Medicare expenditure than any other inpatient procedure. The Comprehensive Care for Joint Replacement model was introduced to decrease cost and improve quality in TJA. The largest portion of episode-of-care costs occurs after discharge. This study sought to quantify the cost variation of primary total hip arthroplasty (THA) according to discharge disposition. METHODS The Medicare and Humana claims databases were used to extract charges and reimbursements to compare day-of-surgery and 91-day postoperative costs simulating episode-of-care reimbursements. Of the patients who underwent primary THA, 257,120 were identified (204,912 from Medicare and 52,208 from Humana). Patients were stratified by discharge disposition: home with home health, skilled nursing facility, or inpatient rehabilitation facility. RESULTS There is a significant difference in the episode-of-care costs according to discharge disposition, with discharge to an inpatient rehabilitation facility the most costly and discharge to home the least costly. CONCLUSION Postdischarge costs represent a sizeable portion of the overall expense in THA, and optimizing patients to allow safe discharge to home may help reduce the cost of THA.

Orthop Rev (Pavia) 2017; 9:7161. [PMID: 29071040 PMCID: PMC5641833 DOI: 10.4081/or.2017.7161] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/27/2017] [Accepted: 05/24/2017] [Indexed: 12/27/2022] Open
Abstract
Without clinical guideline on the optimal timing for primary total hip replacement (THR), patients often receive the operation with delay. Delaying THR may negatively affect long-term health-related quality of life, but its economic effects are unclear. We evaluated the costs and health benefits of timely primary THR for functionally independent adult patients with end-stage osteoarthritis (OA) compared to non-surgical therapy followed by THR after progression to functional dependence (delayed THR), and non-surgical therapy alone (Medical Therapy), from a German Social Health Insurance (SHI) perspective. Data from hip arthroplasty registers and a systematic review of the published literature were used to populate a tunnel-state modified Markov lifetime model of OA treatment in Germany. A 5% annual discount rate was applied to costs (2013 prices) and health outcomes (Quality Adjusted Life Years, QALY). The expected future average cost of timely THR, delayed THR and medical therapy in women at age 55 were €27,474, €27,083 and €28,263, and QALYs were 20.7, 16.7, and 10.3, respectively. QALY differences were entirely due to health-related quality of life differences. The discounted cost per QALY gained by timely over delayed (median delay of 11 years) THR was €1270 and €1338 in women treated at age 55 and age 65, respectively, and slightly higher than this for men. Timely THR is cost-effective, generating large quality of life benefits for patients at low additional cost to the SHI. With declining healthcare budgets, research is needed to identify the characteristics of those able to benefit the most from timely THR.

Abstract
BACKGROUND Recent health care policy changes require hospitals and physicians to demonstrate improved quality. In 2012, a prospective database was formed with the Blue Cross and Blue Shield of Michigan to improve quality of care. The purpose of this study was to analyze patient preoperative medication as predictors of outcomes after total joint arthroplasty. METHODS Data were collected on patient's preoperative medications from 2012 to 2015 using a total joint arthroplasty database. Medications were categorized as antiplatelet, antimicrobial, anticoagulant, narcotic, steroid, insulin, or oral diabetes medication. Outcomes included hospital length of stay (LOS), discharge disposition/destination, and 90-day readmission. Univariate and multivariate regression analyses were performed. RESULTS A total of 3959 patients were studied. Eighty percent (3163 patients) were discharged home. The remainder (795) went to an extended-care facility (ECF). Patients discharged to an ECF were taking more medications (1.13 vs 0.80 in total knee arthroplasty; 1.18 vs 0.83 in total hip arthroplasty; P <.001). Patients who were readmitted took more medications (1.0 vs 0.85; P <.01). There were more discharges to an ECF in narcotic, steroid, and diabetes medication users. Patients taking anticoagulants, narcotics, insulin, and antiplatelets had greater readmission rates. There was a significant correlation between the number of medications and an increased LOS. CONCLUSION Patients taking more medications were more frequently discharged to an ECF and had increased LOS and readmission rates. Narcotics and diabetic medications had the greatest influence. Category and quantity of preoperative medications can be used as predictors of outcomes after arthroplasty surgery.

Abstract
Avascular necrosis (AVN) may confer an increased risk of complications and readmission following total hip arthroplasty (THA). However, current risk-adjustment models do not account for AVN. A total of 1706 patients who underwent THA for AVN from 2011 to 2013 were selected from the American College of Surgeon's National Surgical Quality Improvement Program database and matched 1:1 to controls using a predetermined propensity score algorithm. Rates of 30-day medical and surgical complications, readmissions, and reoperations were compared between cohorts. Propensity-score logistic regression was used to determine independent associations between AVN and outcomes of interest. Patients with AVN had a higher rate of medical complications than those without AVN (20.3% vs 15.3%, respectively; P<.001). Bleeding transfusion was the most common medical complication, occurring at a significantly higher rate in patients with AVN than those without AVN (19.6% vs 13.9%, respectively; P<.001). Patients with AVN were also twice as likely to experience a readmission after THA (odds ratio, 2.093; 95% confidence interval, 1.385-3.164). Avascular necrosis of the femoral head is an independent risk factor for transfusion up to 72 hours postoperatively and readmission up to 30 days following total hip replacement.

Abstract
Background Multimodal protocols of perioperative care may enhance postoperative recovery. However, limited information is available on preoperative immune and carbohydrate (CHO)-enriched drinks in patients undergoing hip arthroplasty. We aimed to investigate the effect of a multimodal protocol (ACERTO protocol) plus preoperative immune nutrition on the length of stay (LOS) and the postoperative acute phase response of patients undergoing total hip arthroplasty. Methods Thirty-two patients (mean age, 58 years; range, 26–85 years; 16 males) were randomized to receive either the ACERTO protocol (n = 15, ACERTO Group), which consisted of 6 h preoperative fasting for solids, an oral drink (200 mL of 12.5 % maltodextrin) up to 2 h before induction of anesthesia, restricted intravenous fluids (only 1000 mL of crystalloid fluid after surgery) and preoperative immune nutrition (600 mL/day of Impact - Nestlé, Brazil) for five days prior to surgery, or traditional care (n = 17; control group), which consisted of 6–8 h preoperative fasting, intravenous hydration until the 1st postoperative day and no preoperative immune supplementation. The main endpoint was LOS. C-reactive protein (CRP) was the secondary endpoint and was assessed during induction of anesthesia and on postoperative day 2. Results Neither deaths nor postoperative complications occurred. The median LOS was 3 (2–5) days in the ACERTO group and 6 (3–8) days in controls (P <0.01). Postoperative CRP was higher in the control group (P <0.01). Conclusion The ACERTO multimodal protocol of perioperative care plus preoperative immune nutrition may decrease LOS and postoperative CRP levels in total hip arthroplasty.

Abstract
Two complications after total hip arthroplasty (THA) are hip instability and limb length discrepancy; instability is a common indication for revision THA. The goal of a successful THA is to maximize impingement-free range of motion, recreate appropriate offset, and equalize limb length discrepancies to produce a pain-free and dynamically stable THA. In this article, the patient risk factors for dislocation and limb length discrepancy, key elements of the preoperative template, the anatomic landmarks for accurate component placement, the leg positions for soft tissue stability testing, and the management of postoperative instability are reviewed.

Abstract
The techniques utilized for the management of articular cartilage and labrum injuries during hip preservation surgery have changed dramatically recently. Conservative treatment may involve image-guided injection of cortisone or viscosupplementation in conjunction with oral NSAIDs and physical therapy. Damage to the labrum runs a broad spectrum, and the treatments are individualized, but span from debridement to repair and reconstruction. The overarching goal of labral treatment is to restore the native functions of the labrum to allow for more normal biomechanical function. Similarly, cartilage injuries can be managed a number of different ways, including with debridement, microfracture or drilling, cartilage transplants, and higher level restorative techniques. These cartilage restoration techniques have evolved rapidly as well, and may include the use of scaffolds, allograft cartilage cells, and other stem-cell-related procedures.
