Potential selection bias in observational studies comparing cervical disc arthroplasty to anterior cervical discectomy and fusion.
This retrospective cohort study looked at potential selection bias for spinal patients undergoing cervical disc arthroplasty (CDA) or anterior cervical discectomy and fusion (ACDF). A total of ACDF or CDA 290,419 procedures were identified in adults from 2004-2014 using ICD-9-CM diagnosis and procedure codes. The vast majority (98.2%) underwent ACDF. CDA patients were younger and healthier with a higher socioeconomic status than ACDF patients. CDA was also $574 more expensive in the fully specified model. There was no statistically significant difference in terms of complications between the two procedures.

Development of a reference chart to monitor postoperative swelling following total knee arthroplasty.
The purpose of this study was to develop a reference chart to monitor postoperative swelling following total knee arthroplasty. Until recently, there was no reliable way to accurately measure swelling in clinical settings, but bioelectrical impedance assessment has shown promise. The authors worked with 56 participants who were followed for the first 7 weeks following total knee arthroplasty. Frequent lower extremity bioelectrical impedance assessment data was collected from the first 40 patients rolled in the study with the remaining 16 patients preliminarily tested. The first 3 days following surgery showed an approximately 10% per day increase with peak swelling occurring 6-8 days after surgery, with a range of 25% for the 10th percentile and 47% for the 90th percentile. It is hoped this monitoring will improve clinical decision making at the individual level.

Trajectory analysis for postoperative pain using electronic health records: a nonparametric method with robust linear regression and K-medians cluster analysis.
Postoperative pain scores are widely monitored and collected in the electronic health record, yet current methods fail to fully leverage the data with fast implementation. This article describes a trajectory analysis for postoperative pain using electronic health records. A robust linear regression was fitted to describe the association between the log-scaled pain score and time from discharge after total knee replacement.

"Surprise" out-of-network billing in orthopedic surgery: charges from surprising sources.
This study examined “surprise” out-of-network billing in orthopedic surgery. Data was analyzed from the Clinformatics DataMart on commercial insured patients undergoing 4 different elective orthopedic procedures from 2012 to 2017: arthroscopic meniscal repair, lumbar discectomy, total knee replacement and total hip replacement. They defined surprise bills as out-of-network bills for procedures done at in-network hospitals. The rate of potential surprise bills was 24.8% for total knee replacement, 24.5% lumbar discectomy, 23.5% for total hip replacement, and 12.5% for meniscal repair. The largest number of surprise bills came from anesthesiologists (39% of all episodes), and durable medical equipment (15%). Per episode, the largest bills came from nonphysician surgical assistants, neurologists, and physician assistants.

Potential role of cost and quality of life in treatment decisions for arthritis-related knee pain in African American and Latina women.
This study examined whether using a decision-making tool would aid Latina and African-American women over age 45 years with arthritic knee pain in making more informed treatment decisions. The researchers conducted 4 focus groups of Latina and African-American women and 2 focus groups with primary care providers who treated them for knee pain. They found that minority women and primary care providers all endorsed the use of a decision-making tool that provided information on the impact of treatment on quality of life, medical care costs, and work productivity.

What outcomes matter to patients after joint or spine surgery?
In this study, semi-structured interviews were conducted with 65 patients undergoing hip or knee replacement, spinal discectomy/laminectomy, or a spinal fusion to examine what patient-reported outcome measures (PROMs) patients identified as most important. The investigators found that patients identified specific preferred outcomes from these surgical procedures that were important and meaningful to them and that framed whether they saw their surgery as a success. They also identified personal factors that they assumed their surgeons knew about, which affected their care and recovery.

Patient-reported outcomes following total hip arthroplasty: a multicenter comparison based on surgical approaches.
This study looked at patient-reported outcomes (PROs) from patients who underwent total hip arthroplasty (THA) in the United States. The cohort examined were participants in the Comparative Effectiveness of Pulmonary Embolism Prevention after Hip and Knee Replacement study. The researchers compared PROs between posterior, transgluteal, and anterior surgical approaches to THA. Patients were surveyed on function, global health and pain at 1, 3, and 6 months postoperatively at 26 sites from the clinical trial. Outcomes from 3018 eligible participants were examined from December 2016 through August 2019. While there was lower improvement in hip disability and Osteoarthritis Outcomes Score at first with the transgluteal cohort, by 3 and 6 months there was no clinically significant differences between the three groups.

The effects of bundled payment programs for hip and knee arthroplasty on patient-reported outcomes.
This study compared outcomes for patients undergoing hip and knee arthroplasty at hospitals participating in Medicare’s bundled payment programs with hospitals that do not. They performed a prospective observational study using the Comparative Effectiveness of Pulmonary Embolism Prevention after Hip and Knee replacement trial. Differences through 6 months were observed. Outcomes were described using the brief Knee Injury and Osteoarthritis Outcomes Score or the brief Hip Disability and Osteoarthritis Outcomes Score, the Patient-Reported Outcomes Measurement Information System Physical Health Score, and the Numeric Pain Rating Scale. While there slightly lower improvement at nonbundled hospitals at first, overall the effects were small.

Person-centered care and physical therapy: a "people-like-me" approach.
In this article the authors propose developing "people-like-me" reference charts, generated with historical outcomes data, to provide real-time information on an individual's status relative to similar people, using as an example people rehabilitating after total knee arthroplasty. The authors propose this framework as a practical mechanism to advance person-centered decisions in physical therapy according to the ideals of evidence-based practice.

Integrating adjuvant analgesics into perioperative pain practice: results from an academic medical center.
This study evaluated adjuvant analgesic gabapentin use after total knee arthroplasty (TKA) surgery and its effects on opioid use, pain, and readmissions. This retrospective observational study included 4,046 TKA recipients from 2009 to 2017 using electronic health records from an academic tertiary care medical institute. Overall, there was an 8.72% annual increase in gabapentin use which was associated with a significant decrease in opioid consumption in modeled estimates. Patients receiving gabapentin had similar discharge and follow-up pain scores, and 30-day unplanned readmission rates compared with patients receiving no adjuvant analgesics.

Patient outcomes following total joint replacement surgery: a comparison of hospitals and ambulatory surgery centers.
This study used a large claims database of non-Medicare patients to examine inpatient and outpatient total knee replacement and total hip replacement surgery performed on a near-elderly population during 2014-2016. Findings support the argument that outpatient total joint replacement is appropriate for select patients treated in both hospital outpatient departments and ambulatory surgery centers, although in the commercially insured population, the latter services may come at a cost. Until further study of outpatient total joint replacement in the Medicare population becomes available, how this will extrapolate to the Medicare population is unknown.

The impact of decision aids on adults considering hip or knee surgery.
Investigators analyzed data for 2012-2015 about patients within the ten High Value Healthcare Collaborative member systems who were exposed to condition-specific decision aids in the context of consultations for hip and knee osteoarthritis, with the intention that the aids be used to support shared decision making. They found that, compared to matched patients not exposed to the decision aids, those exposed had two-and-a-half times the odds of undergoing hip replacement surgery and nearly twice the odds of undergoing knee replacement surgery within six months of the consultation. Their findings suggest that health care systems adopting decision aids developed for use in shared decisionmaking, and used in conjunction with hip and knee osteoarthritis consultations, should not expect reduced surgical utilization.

Using cluster analysis to identify patient factors linked to differential functional gains after total knee arthroplasty.
This study used cluster analysis to identify patient factors linked to different outcomes following total knee arthroplasty (TKA). The study analyzed Short Form 36 Physical Component Score (PCS) trajectories of 656 patients at 3 time points over a 1-year period. The MultiExperiment View (MeV) built-in bootstrapping method was used to assess statistical significance of the clusters. They found two distinct clusters: Cluster 1 included 550 patients (84%) who demonstrated persistent improvement at 6 and 12 months. The remainder of patients consisted of Cluster 2 who demonstrated decline in PCS at 6 months but improved by 12 months. Cluster 1 was found to have higher baseline mental health scores, lower baseline PCS, and a significantly higher proportion of non-Hispanic Whites compared to Cluster 2.

Racial disparities in total knee replacement failure as related to poverty.
The authors sought to determine whether racial disparities in total knee replacement (TKR) failure are explained by poverty. Linking New York state patients to residential census tracts by geocoded addresses, they found that there was a trend toward higher TKR revision risk in blacks, but poverty did not modify the relationship between race and TKR revision or failure.

Association of early postoperative pain trajectories with longer-term pain outcome after primary total knee arthroplasty.
Studies to date have not comprehensively examined pain experience after total knee arthroplasty (TKA). Discrete patterns of pain in this period might be associated with pain outcomes at 6 to 12 months after TKA. The purpose of this study was to examine patterns of individual post-TKA pain trajectories and to assess their independent associations with longer-term pain outcome after TKA.

Do skills acquired from training with a wire navigation simulator transfer to a mock operating room environment?
This study compared performance of residents getting traditional and simulation orthopedic surgery training at three medical centers: University of Iowa, University of Minnesota, and the Mayo Clinic. All residents first received traditional training in how to treat an intertrochanteric fracture. Then the groups were divided up with two groups getting additional simulated-based training and another group getting proficiency training for specific components of wire navigation. The two simulation-based training groups performed better in lower tip-apex distance than the traditional training group. Residents in the proficiency training group used more images than the other groups.

Patterns and costs of 90-day readmission for surgical and medical complications following total hip and knee arthroplasty.
Unplanned readmissions following elective total hip (THA) and knee (TKA) arthroplasty as a result of surgical complications likely have different quality improvement targets and cost implications than those for nonsurgical readmissions. In this study, the investigators compared payments, timing, and location of unplanned readmissions with Center for Medicare and Medicaid Services (CMS)-defined surgical complications to readmissions without such complications.

An extensible orthopaedic wire navigation simulation platform.
The demand for simulation-based skills training in orthopaedics is steadily growing. Wire navigation, or the ability to use 2D images to place an implant through a specified path in bone, is an area of training that has been difficult to simulate given its reliance on radiation based fluoroscopy. The investigators group previously presented on the development of a wire navigation simulator for a hip fracture module. In this paper, they present a new methodology for extending the simulator to other surgical applications of wire navigation.

A qualitative study of the postoperative pain management educational needs of total joint replacement patients.
This study examined the challenges of pain management education for post-surgery of total joint replacement patients. The majority of patients have pain in the postoperative period and managing pain can be challenging. Nine orthopedic surgeons’ offices in 8 states recruited patients and 27 patients completed the interview. They were interviewed with open-ended questions on their experiences with pain after surgery, pain management, experiences with pain medicine, experience using non-medicine-related pain reduction methods, and suggestions for better pain management education. Challenges included lack of pain control and lack of information about prescribed opioid and nonopioid methods of managing pain.

Variation in the delivery of inpatient orthopaedic care to Medicaid beneficiaries within a single metropolitan region.
This study examined rates of Medicaid-funded surgical procedures for orthopedic patients. The authors hypothesized that orthopedists and hospitals are often unwilling to perform surgery on underinsured patients. The payer mix was examined for select inpatient orthopedic surgical procedures within a single region, including elective cases (total knee or hip arthroplasty; spinal decompression or fusion) and trauma cases (hip hemiarthroplasty; femoral or tibial or fibular fracture repair) among 22 hospitals from 2011 to 2016 for patients aged 18 to 64 years. For all cases (n = 19,204) the mean percentage of Medicaid-funded surgical procedures was 7.6%. Elective surgery cases were 5.5% and trauma cases 14.7% which supports their beliefs about delivery rates of orthopedic care on the basis of socioeconomic markers.

Association of preoperative opioid use with mortality and short-term safety outcomes after total knee replacement.
The purpose of this study was to determine the association of preoperative opioid use among patients 65 years and older with mortality and other complications at 30 days post-total knee replacement (TKR). Findings show that continuous opioid users had a higher risk of revision operations, vertebral fractures, and opioid overdose at 30 days post-TKR but not of in-hospital or 30-day mortality, compared with opioid-naive patients. Highlights include the need for better understanding of patient characteristics associated with chronic opioid use to optimize preoperative assessment of overall risk after TKR.

Impact of Medicare readmissions penalties on targeted surgical conditions.
The authors used Medicare claims to evaluate the effects of the 2013 expansion of the Hospital Readmissions Reduction Program on risk-adjusted readmission rates, episode payments, lengths-of-stay, and observation status use for hip and knee replacement surgery. They found that medical readmission penalties led to readmission reductions for surgical patients, that targeted surgical penalties did not have an additional effect, and that readmission reductions are approaching a point below which further reductions may be unlikely.

Improvement in mental health following total hip arthroplasty: the role of pain and function.
This prospective study examined whether mental health improved in patients who had total hip arthroplasty (THA) due to improvement in pain and function 1 year post-surgery. Patients enrolled in a THA registry from 2010 to 2014 were included and the mental component score (MCS) was examined before and 1 year post-surgery. There was a significant improvement in mental health due to less pain and improved function.

A 12-item short form of the Hip disability and Osteoarthritis Outcome Score (HOOS-12): tests of reliability, validity and responsiveness.
The goal of this study was to measure validity, reliability and responsiveness of the 12-item version of the 40-item Hip disability and Osteoarthritis Outcome Score (HOOS) surveys that measure joint-specific pain, function and quality of life (QOL) for patients. The shorter forms were given to 1,281 hip OA patients from the FORCE-TJR cohort who had previously completed the HOOS surveys before and after total joint replacement surgery. The HOOS-12 survey was compared to the full-length HOOS, HOOS-PS, and HOOS, JR surveys. Internal consistency reliability was above 0.70 for all HOOS-12 scales and above 0.90 for the Summary score. Validity and responsiveness were also found to be comparable to full-length HOOS scales.
