Due to limitations of existing pharmacological therapies for the management of chronic pain in osteoarthritis (OA), surgical interventions remain a major component of current standard of care, with total joint replacements (TJRs) considered for people who have not responded adequately to conservative treatment. This study aimed to quantify the economic burden of moderate-to-severe chronic pain in patients with OA in England prior to TJR. A retrospective, longitudinal cohort design was employed using Clinical Practice Research Datalink GOLD primary care data linked to Hospital Episode Statistics secondary care data in England. Patients (age ≥18 years) with an existing OA diagnosis of any anatomical site (Read/ICD-10) were indexed (Dec-2009 to Nov-2017) on a moderate-to-severe pain event (which included TJR) occurring within an episode of chronic pain. 5-year TJR rates from indexing were assessed via Kaplan-Meier estimates. All-cause healthcare resource utilisation and direct medical costs were evaluated in the 1–12 and 13–24 months prior to the first TJR experienced after index. Statistical significance was assessed via paired t-tests. The study cohort comprised 5,931 eligible patients (57.9% aged ≥65 years, 59.2% female). 2,176 (36.7%) underwent TJR (knee: 54.4%; hip: 42.8%; other: 2.8%). The 5-year TJR rate was 45.4% (knee: 24.3%; hip: 17.5%; other: 6.8%). Patients experienced more general practitioner consultations in 1–12 months pre-TJR compared with 13–24 months pre-TJR (means: 12.13 vs. 9.61; p<0.0001), more outpatient visits (6.68 vs. 3.77; p<0.0001), more hospitalisations (0.74 vs. 0.62; p=0.0032), and more emergency department visits (0.29 vs. 0.25, p=0.0190). Total time (days) spent as an inpatient was higher in 1–12 months pre-TJR (1.86 vs. 1.07; p<0.0001). Mean total per-patient cost pre-TJR increased from £1,771 (13–24 months) to £2,621 (1–12 months) (p<0.0001). Resource-use and costs incurred were substantially greater in the 12 months immediately prior to TJR, compared with 13–24 months prior. Reasons for increased healthcare and economic burden in the pre-TJR period deserve further exploration as potential targets for efforts to improve patient experience and efficiency of care

Aims

The aim of this study was to determine whether total hip arthroplasty (THA) for chronic hip pain due to unilateral primary osteoarthritis (OA) has a beneficial effect on cognitive performance.

Objectives

The purpose of this study was to assess N-acetyl aspartate changes in the thalamus in patients with osteoarthritis of the hip using proton magnetic resonance spectroscopy.

Literature data show varying rates of aseptic loosening of standard hemispherical cups after primary total hip arthroplasty (THA) in patients with Crowe IV developmental dysplasia of the hip (DDH). In order to improve the results regarding the frequency of aseptic loosening of the acetabular component, we decided to use custom-made acetabular implants (CMAI) in this category of patients. The aim of our study was to report outcomes after primary THA using CMAI in patients with Crowe IV DDH. We retrospectively analyzed the results of primary THA using the CMAI in 58 hips. The mean follow-up period was 5.2 years (range 4.2 – 6.3). Patients demonstrated improved functional outcomes according to the Oxford Hip Score: preoperatively 16.9 and postoperatively 38.5 (P < 0.05). Revisions were performed in 2 cases due to dislocations, in 1 case due to nonunion of the greater trochanter and in 1 case due to chronic pain syndrome caused by contact of the CMAI flange with the iliopsoas muscle. In a patient with chronic pain syndrome, during the revision, the pubic flange of the CMAI, which was in contact with the iliopsoas muscle, was removed. There were no radiological signs of loosening of the CMAI. The use of CMAI shows good results in patients with DDH. Extended capability for supplementary screw fixation is an excellent feature of such implants, allowing them to obtain reliable primary fixation. Further observation is required to assess CMAI in the long-term follow-up

There is some evidence to suggest that outcomes of THA in patients with minimal radiographic osteoarthritis may not be associated with predictable outcomes. The aim of this study was to:. Assess the outcome of patients with hip pain who underwent THA with no or minimal radiographic signs of osteoarthritis,. Identify patient comorbidities and multiplanar imaging findings which are predictive of outcome,. Compare the outcome in these patients to the expected outcome of THA in hip OA. A retrospective review of 107 hips (102 patients, 90F:12M, median age 40.6, IQR 35.1–45.8 years, range 18–73) were included for analysis. Plain radiographs were evaluated using the Tonnis grading scale of hip OA. Outcome measures were all-cause revision; iHOT12; EQ-5D; Oxford Hip Score; UCLA Activity Scale; and whether THA had resulted in the patient's hip pain and function being Better/Same/Worse. The median Oxford Hip Score was 33.3 (IQR 13.9, range 13–48), and 36/107 (33.6%) hips achieved an OHS≥42. There was no association between primary hip diagnosis and post-operative PROMs. A total of 91 of the 102 patients (89.2%, 93 hips) reported that their hip pain and function was Better than prior to THA and would have the surgery again, 7 patients (6.8%, 10 hips) felt the Same, and 4 patients (3.9%, 4 hips) felt Worse and would not have the surgery again. Younger patients undergoing total hip arthroplasty with no or minimal radiographic osteoarthritis had lower postoperative Oxford Hip Scores than the general population; though most felt symptomatically better and knowing what they know now, would have surgery again. Those with chronic pain syndrome or hypermobility were likely to benefit less. Those with subchondral cysts or joint space narrowing on CT imaging were more likely to achieve higher functional scores and satisfaction

Patients undergoing total hip or knee arthroplasty (THA/TKA) are commonly associated with high pain scores and narcotic use. Duloxetine is effective in relieving chronic pain. The aim of this study was to evaluate the safety and efficacy of duloxetine for pain management following THA/TKA. Five major databases (PubMed, Embase, Scopus, Cochrane, and Web of Science) were searched for randomised controlled trials (RCTs) that compared duloxetine to placebo in patients that underwent THA/TKA. The primary outcome was pain reduction with rest and movement at short-term and long-term time intervals. Secondary outcomes were the use of analgesics, length of stay, and safety profile. The risk of bias was assessed using the Cochrane tool. Data were pooled using RevMan 5.4. The results were reported as mean difference (MD) or standardised MD (SMD) and 95% confidence intervals (CI). Eight RCTs with 767 patients were included. 50.2% (n=385/767) of patients received duloxetine. After one day, duloxetine was superior to the control regarding pain reduction with rest (SMD= −0.22 [−0.41, −0.03], p=0.02) after sensitivity analysis and pain reduction at movement (SMD= −0.39 [−0.55, −0.24], p<0.001). Similarly, after 12 weeks, duloxetine significantly reduced pain with rest (SMD= −0.3 [−0.52, −0.09], p=0.006) and pain with movement (SMD= −0.52 [−0.87, −0.17], p=0.003). In addition, after sensitivity analysis, duloxetine was associated with less analgesic use after one day (MD= −4.65 [−7.3, −2.01], p<0.001) and two days (MD= −5.65 [−10.62, −0.67], p=0.03). Patients who received duloxetine also required fewer analgesics after three days. However, there was no significant difference between the duloxetine and control groups in analgesic use after one week, length of stay, and adverse events. Duloxetine was superior to the placebo regarding short-term and long-term pain reduction with rest and movement following THA/TKA. Duloxetine reduced postoperative analgesic use. There was no significant difference between duloxetine and placebo regarding adverse events and length of stay

Introduction. The long-term survival of modern ceramic-ceramic bearings in young active patients with osteonecrosis undergoing total hip arthroplasty (THA) is unknown. A previously published study of this series at 5-year follow-up demonstrated an extremely high activity level. The purpose of this study is to examine whether this very high activity level is associated with ceramic-on-ceramic THA failure at long-term follow-up. Methods. This is a retrospective review of a single-surgeon at an academic medical center between years 2003–2010. Inclusion criteria were consecutive series of ceramic-on-ceramic articulations in patients younger than 50 with a diagnosis of osteonecrosis. Median follow-up was 12.4 years (range 10–17). Data was collected via mail, telephone, and e-mail surveys. Exclusion criteria included deceased prior to follow-up. Preoperative and postoperative Western Ontario and McMaster University Arthritis Index (WOMAC) and University of California at Los Angeles Activity scores (UCLA) were collected. Student t-tests were used as appropriate. Results. There were 108 hips in this series. Median age at THA was 37 (range 14–50). Average preoperative BMI was 27 (range 19–40). The vast majority of patients were highly active at latest follow-up (76% with UCLA scores between 7 and 10). WOMAC scores (1–100 scale) increased from preoperative mean of 41.1 to postoperative 83.8 (p<0.00.1, 98% power, effect size 1). UCLA scores (1–10 scale) improved from a preoperative mean of 3.3 to postoperative 7.2 (p<0.001, 97% power, effect size 1). At 12 years median follow-up, 4 patients had undergone revision surgery. There were no ceramic component failures. One patient underwent early revision for femoral component loosening, one was revised for chronic pain at another institution, one patient was revised for instability at 5 years post-op, and one patient was revised for periprosthetic fracture at 10 years. Conclusion. At long-term follow-up, ceramic bearings accommodate high activity level with excellent component longevity in young patients undergoing THA

Introduction. Due to the opioid epidemic, our service developed a cultural change highlighted by decreasing discharge opioids after lower extremity arthroplasty. However, concern of potentially increasing refill requests exists. As such, the goal of this study was to analyze whether decreased discharge opioids led to increased postoperative opioid refills. Methods. We retrospectively reviewed 19,428 patients undergoing a primary hip or knee arthroplasty at a single institution from 2016–2019. Patients that underwent secondary procedures within that timeframe were excluded. Two-thousand two-hundred and forty-one patients (12%) were on narcotics preoperatively or had chronic pain syndrome. Two reductions in routine discharge narcotics were performed over this timeframe. First, 8,898 patients routinely received 750 morphine milligram equivalents (MMEs). After the first reduction, 4,842 patients routinely received 520 MMEs. After a second reduction, 5,688 patients routinely received 320 MMEs. We analyzed refill rates, refill MMEs, and whether discharge MMEs were associated with refill MMEs in a multivariate model. Results. Opioid refill rates were 28%, 32%, and 33% in each timeframe (p=0.001). Significantly fewer patients received narcotic refills after 6 weeks in the 320 MME group (8%) compared to the 750 MME group (6%, p=0.02). Total refill MMEs reduced significantly from a mean of 282 in the first to 227 in the last timeframe (p<0.001). After controlling for age, sex, BMI, history of anxiety/depression, and procedure type, opioid discharge of <400 MMEs was not a risk factor for increased refill MMEs in opioid-naïve patients (p=0.23). Conclusion. While decrease in MMEs prescribed at discharge after arthroplasty led to a slight increase in the number of opioid refills (5%), there was a reduction in total refill MMEs. Furthermore, less patients received refills beyond 6 weeks postoperatively. This institutional cultural change led to a reduction in opioid prescriptions after primary arthroplasty equivalent to 500,000 oxycodone 5 mg tablets

Aims

Pain is the most frequent complaint associated with osteonecrosis of the femoral head (ONFH), but the factors contributing to such pain are poorly understood. This study explored diverse demographic, clinical, radiological, psychological, and neurophysiological factors for their potential contribution to pain in patients with ONFH.

Aims

The aim of this study was to compare open reduction and internal fixation (ORIF) with revision surgery for the surgical management of Unified Classification System (UCS) type B periprosthetic femoral fractures around cemented polished taper-slip femoral components following primary total hip arthroplasty (THA).

Aims

Better prediction of outcome after total hip arthroplasty (THA) is warranted. Systemic inflammation and central neuroinflammation are possibly involved in progression of osteoarthritis and pain. We explored whether inflammatory biomarkers in blood and cerebrospinal fluid (CSF) were associated with clinical outcome, and baseline pain or disability, 12 months after THA.

Introduction. Depression is a common co-morbidity in Total Hip Arthroplasty (THA). Chronic pain and depression influence one another. Postoperative outcomes and satisfaction rates are affected by depression. Objectives. The aim of the study was to determine the impact of pre-operative depression on patient functional outcomes and satisfaction rates after THA. A secondary objective was to assess potential change in the incidence of depression at mid-term post-operative follow-up. Study Design & Methods. We retrospectively reviewed 200 patients undergoing THA from 2015–2016 at a single academic institution.150 (75%) of patients were followed up at a minimum of 24 months. Patients pre-operative depression symptoms were assessed according to the Zung Self-reported depression score and the PHQ-9 scores. Functional scores, satisfaction rates, expectation rates and 30- and 90-day readmission rates were correlated with pre-operative and 2-year follow-up depression scores. Results. There were 103 females and 47 males with an average age of 60.1 years (22–89 years old). The Patient Health Questionnaire (PHQ-9) correlated with the Zung Self-reported depression scores. Overall, 73 patients (48.7%) were classified as being depressed pre-operatively. There were 48 (32.2%) with mild depression and 19 (12.8%) with marked depression. Females, HIV-infected and morbidly obese patients were more likely to be depressed. The mean pre-operative Harris Hip Score (HHS) was 35.95 (24–66) and Oxford Hip Score (OHS) 17.11 (0–48). The 30-day readmission rate was 2% and all patients were pre-operatively severely depressed. At a minimum of 2 years there was an improvement in Zung Self-Rating Depression Scale and PHQ-9 scores. Only 29 (18.8%) patients were depressed. There were 55 patients who progressed from depressed to non-depressed (p=0.00), while 11 patients (7.4%) became depressed after THA (p=0.00). The least improvement in both OHS and HHS was in the severely depressed group (p<0.05). The overall satisfaction rate was 89.7%. Depressed patient satisfaction rate was 86.9% with only 70.27% of the severely depressed group satisfied post-operatively. Age (>70) and BMI >40 correlated with dissatisfaction (p<0.05). Conclusions. There is a high prevalence of depression in THA. Incorporation of psychological management strategies may improve satisfaction rates and functional outcomes post-THA

Aims

Social media is a popular resource for patients seeking medical information and sharing experiences. periacetabular osteotomy (PAO) is the gold-standard treatment for symptomatic acetabular dysplasia with good long-term outcomes. However, little is known regarding the perceived outcomes of PAO on social media. The aims of this study were to describe the perceived outcomes following PAO using three social media platforms: Facebook, Instagram, and X (formerly known as Twitter).

Aims

Hip arthroscopy (HA) has become the treatment of choice for femoroacetabular impingement (FAI). However, less favourable outcomes following arthroscopic surgery are expected in patients with severe chondral lesions. The aim of this study was to assess the outcomes of HA in patients with FAI and associated chondral lesions, classified according to the Outerbridge system.

Total hip replacement (THR) is a very common procedure undertaken in up to 285 000 Americans each year. Patient satisfaction with THR is very high, with improvements in general health, quality of life, and function while at the same time very cost effective. Although the majority of patients have a high degree of satisfaction with their THR, 27% experience some discomfort, and up to 6% experience severe chronic pain. Although it can be difficult to diagnose the cause of the pain in these patients, this clinical issue should be approached systematically and thoroughly. A detailed history and clinical examination can often provide the correct diagnosis and guide the appropriate selection of investigations, which will then serve to confirm the clinical diagnosis made. .

Aims

The aim of this study was to understand the experience of mature patients who undergo a periacetabular osteotomy (PAO), a major hip-preserving surgical procedure that treats symptomatic hip dysplasia by realigning the acetabulum. Our aim was to improve our understanding of how the operation affected the lives of patients and their families, with a long-term goal of improving their experience.

Aims

The aim of this study was to estimate time to arthroplasty among patients with hip and knee osteoarthritis (OA), and to identify factors at enrolment to first-line intervention that are prognostic for progression to surgery.

Aims

The Patient-Reported Outcomes Measurement Information System (PROMIS) has demonstrated faster administration, lower burden of data capture and reduced floor and ceiling effects compared to traditional Patient Reported Outcomes Measurements (PROMs). We investigated the suitability of PROMIS Mobility score in assessing physical function in the sequelae of childhood hip disease.

Aims

Due to the opioid epidemic in the USA, our service progressively decreased the number of opioid tablets prescribed at discharge after primary hip (THA) and knee (TKA) arthroplasty. The goal of this study was to analyze the effect on total morphine milligram equivalents (MMEs) prescribed and post-discharge opioid repeat prescriptions.

Aims

We present the development of a day-case total hip arthroplasty (THA) pathway in a UK National Health Service institution in conjunction with an extensive evidence-based summary of the interventions used to achieve successful day-case THA to which the protocol is founded upon.
