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). Methods. Facebook, Instagram, and X posts were retrospectively collected from 1 February 2023. Facebook posts were collected from the two most populated interest groups: “periacetabular osteotomy” and “PAO Australia.” Instagram and X posts were queried using the most popular hashtags: #PAOwarrior, #periacetabularosteotomy, #periacetabularosteotomyrecovery, #PAOsurgery, and #PAOrecovery. Posts were assessed for demographic data (sex, race, location), perspective (patient, physician, professional organization, industry), timing (preoperative vs postoperative), and perceived outcome (positive, negative, neutral). Results. A total of 1,054 Facebook posts, 1,003 Instagram posts, and 502 X posts were consecutively assessed from 887 unique authors. The majority (63.3%) of these posts were from patients in the postoperative period, with a median of 84 days postoperatively (interquartile range 20 to 275). The longest follow-up timeframe postoperatively was 20 years. Regarding perceived outcomes, 52.8% expressed satisfaction, 39.7% held neutral opinions, and 7.5% were dissatisfied. Most dissatisfied patients (50.9%) reported pain (chronic or uncontrolled acute) as an attributing factor. Conclusion. Most PAO-perceived surgical outcomes on social media had a positive tone. Findings also indicate that a small percentage of patients reported negative perceived outcomes. However, dissatisfaction with PAO primarily stemmed from postoperative pain. Social media posts from other sources (physicians, hospitals, professional organizations, etc.) trend towards neutrality. Healthcare providers must consider the social media narratives of patients following PAO, as they may reveal additional outcome expectations and help improve patient-centred care, create informed decision-making, and optimize treatment outcomes.

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. This work aimed at answering the following research questions: 1) What is the rate of mechanical complications, nonunion and infection for head/neck femoral fractures, intertrochanteric fractures, and subtrochanteric fractures in the elderly USA population? and 2) Which factors influence adverse outcomes?. Methods. Proximal femoral fractures occurred between 1 January 2009 and 31 December 2019 were identified from the Medicare Physician Service Records Data Base. The Kaplan-Meier method with Fine and Gray sub-distribution adaptation was used to determine rates for nonunion, infection, and mechanical complications. Semiparametric Cox regression model was applied incorporating 23 measures as covariates to identify risk factors. Results. Union failure occured in 0.89% (95% confidence interval (CI) 0.83 to 0.95) after head/neck fracturs, in 0.92% (95% CI 0.84 to 1.01) after intertrochanteric fracture and in 1.99% (95% CI 1.69 to 2.33) after subtrochanteric fractures within 24 months. A fracture-related infection was more likely to occur after subtrochanteric fractures than after head/neck fractures (1.64% vs 1.59%, hazard ratio (HR) 1.01 (95% CI 0.87 to 1.17); p < 0.001) as well as after intertrochanteric fractures (1.64% vs 1.13%, HR 1.31 (95% CI 1.12 to 1.52); p < 0.001). Anticoagulant use, cerebrovascular disease, a concomitant fracture, diabetes mellitus, hypertension, obesity, open fracture, and rheumatoid disease was identified as risk factors. Mechanical complications after 24 months were most common after head/neck fractures with 3.52% (95% CI 3.41 to 3.64; currently at risk: 48,282). Conclusion. The determination of complication rates for each fracture type can be useful for informed patient-clinician communication. Risk factors for complications could be identified for distinct proximal femur fractures in elderly patients, which are accessible for therapeutical treatment in the management.

Introduction. The purpose of the study was to determine access to and, ability to use telemedicine technology in an adult hip and knee reconstruction patient population and we seek to understand these patients' perceived benefits, risks and preferences of telemedicine. Methods. We performed a cross-sectional telephone administered survey on patients scheduled to undergo primary THA and TKA by one of six surgeons at a single academic institution between March 23 and June 2, 2020. Results. 163 patients were contacted and 113 (69.3%) completed the survey. Of the patients that completed surveys, 88% of patients reported using the internet with 94% reporting owning a device capable of videoconferencing. 78% of patients had participated in a video call in the past year and 37% having done a video visit with their physician. When asked for their preferred method for a physician visit, 80% ranked in-person as their first choice, followed by 18% preferring a video visit. Perceived benefits of telemedicine visits included reduced travel to appointments (87% agree or strongly agree) and reduced cost of attending appointments (63% agree or strongly agree). However, patients were concerned that they would not establish the same patient-physician connection (51% agree or strongly agree) and would not receive the same level of care (33% agree or strongly agree) through telemedicine visits versus in person visits. Conclusion. The majority of total hip and knee arthroplasty patients have access to and are capable of using the technology required for telemedicine visits. However, patients still prefer to have in person visit over concern that they will not establish the same patient-physician connection and will not receive the same level of care, despite benefits of reduced time spent traveling to and cost of attending appointments, and making it easier to attend appointments

Aims. The purpose of this study is to evaluate early outcomes with the use of a smartphone-based exercise and educational care management system after total hip arthroplasty (THA) and demonstrate decreased use of in-person physiotherapy (PT). Methods. A multicentre, prospective randomized controlled trial was conducted to evaluate a smartphone-based care platform for primary THA. Patients randomized to the control group (198) received the institution’s standard of care. Those randomized to the treatment group (167) were provided with a smartwatch and smartphone application. PT use, THA complications, readmissions, emergency department/urgent care visits, and physician office visits were evaluated. Outcome scores include the Hip disability and Osteoarthritis Outcome Score (HOOS, JR), health-related quality-of-life EuroQol five-dimension five-level score (EQ-5D-5L), single leg stance (SLS) test, and the Timed Up and Go (TUG) test. Results. The control group was significantly younger by a mean 3.0 years (SD 9.8 for control, 10.4 for treatment group; p = 0.007), but there were no significant differences between groups in BMI, sex, or preoperative diagnosis. Postoperative PT use was significantly lower in the treatment group (34%) than in the control group (55.4%; p = 0.001). There were no statistically significant differences in complications, readmissions, or outpatient visits. The 90-day outcomes showed no significant differences in mean hip flexion between controls (101° (SD 10.8)) and treatment (100° (SD 11.3); p = 0.507) groups. The HOOS, JR scores were not significantly different between control group (73 points (SD 13.8)) and treatment group (73.6 points (SD 13); p = 0.660). Mean 30-day SLS time was 22.9 seconds (SD 19.8) in the control group and 20.7 seconds (SD 19.5) in the treatment group (p = 0.342). Mean TUG time was 11.8 seconds (SD 5.1) for the control group and 11.9 (SD 5) seconds for the treatment group (p = 0.859). Conclusion. The use of the smartphone care management system demonstrated similar early outcomes to those achieved using traditional care models, along with a significant decrease in PT use. Noninferiority was demonstrated with regard to complications, readmissions, and ED and urgent care visits. This technology allows patients to rehabilitate on a more flexible schedule and avoid unnecessary healthcare visits, as well as potentially reducing overall healthcare costs.

Introduction. Recent literature has sought to quantify pre-operative work associated with total joint arthroplasty. These studies have utilized surveys or self-reported time logs to estimate the Pre-op Optimization Work (POW) completed by the surgical team. The purpose of this study was to objectively quantify POW associated with total hip arthroplasty (THA) using electronic medical record (EMR) activity audit logs. Methods. Retrospective analysis of EMR activity for 4 arthroplasty surgeons and their clinical staff was collected for 100 consecutive THA cases (25 per surgeon). Clinical informatics data was generated using EMR activity audit logs for pre-THA activity. Every action and mouse-click within a patient's chart was recorded for each team member. The time between mouse-clicks was calculated and summed for each user. Times exceeding five minutes without activity were assumed to reflect inactivity and excluded. Descriptive statistics were used to estimate the POW associated with THA preparation. Results. The mean number of days for pre-THA time period was70.7 (SD43.9; range: 8–175days). During this period, the mean time spent in each patient's chart was 75.5 minutes (SD50.75) minutes. Surgeon's POW in the medical record accounted for 7.3(SD6.7) of these minutes. Much of the work was conducted by nurses (47.0 minutes, SD43.4), physician extenders (10.8 minutes, SD 13.1), and qualified office staff/technicians (10.4 minutes, SD14.9). The majority of work captured in the EMR activity log was associated with medication review, patient optimization, documentation of necessary medical clearances, ordersets, patient communication, and prior authorization requests. Conclusion. A considerable amount of preoperative work is required between the clinic date a patient decides to pursue THA and the day prior to surgery. These retrospective electronic time stamp measurements should represent the absolute minimum time required for surgical preparation

Background. The purpose of this study is to evaluate the early outcomes with the use of a smartphone-based exercise and educational platform after primary total hip arthroplasty compared to a standard of care control group. Methods. A multicenter prospective randomized control trial was conducted evaluating the use of the mymobility smartphone-based care platform for primary total hip arthroplasty (THA). Patients randomized to the control group (198 patients) received the respective institution's standard of care. Those randomized to mymobility treatment group (167 patients) were provided an Apple Watch and mymobility smartphone application. The application provides pre and postoperative educational content, video directed exercise programs as well as tracks the patient's activity. Patients in the treatment group were not initially prescribed physical therapy, but could be if their surgeon deemed it necessary. Early outcomes assessed included 90-day hip range of motion, HOOS JR scores, 30-day single leg stance (SLS) and time up and go (TUG) test. We also evaluated PT utilization, THA complications associated with readmissions, ER visits not associated with readmissions, urgent care (non standard of care) visits, and physician office visits. Outcome scores include HOOS-Jr, EQ-5D-5L, single stance (SLS), Timed up and go (TUG). Satisfaction scores for the procedure and the mymobility study group were also recorded. Results. The control group was significantly younger by 3.0 years (p=0.007), but no significant difference between groups in BMI, gender or preoperative diagnosis. Postoperative PT utilization was statistically lower in the mymobility group. (P=.001). There were no statistically significant differences in complications, readmissions, or office visits. The 90-day outcomes showed no significant differences in hip flexion between controls (101.3±10.9) and mymobility (99.8 ±12) (p=0.34). HOOS JR scores were not significantly different between control group (84 ±14.5) and mymobility group (81 ±13) (p=0.15). Mean 30-day SLS time was 22.5 ±20 sec in the control group and 19.8 ±19 sec in the mymobility group (p=0.25). Mean TUG time was 14.1 ±27.4 sec for control group and 16.1 ±43.3 sec for my mobility group (p=0.7). Conclusion. The use of the mymobility care platform demonstrated similar early outcomes to traditional care models. This study showed a significant decrease in PTA utilization. Initial findings demonstrated non inferiority of the mymobility platform with regards to complications, readmissions, emergency room and urgent care visits. Strengths of this study include randomized, multicentered study design. Both groups were balanced except for age. Weakness of this study is the lack of preoperative functional testing which may influence postoperative single stance. This technology allows patients to rehabilitate on a more flexible schedule, avoid unnecessary healthcare visits as well as potentially decrease overall healthcare costs

Aims. The aim of this study was to assess the efficacy of non-selective and selective non-steroidal anti-inflammatory drugs (NSAIDs) in preventing heterotopic ossification (HO) after total hip arthroplasty (THA). Methods. A thorough and systematic literature search was conducted and 29 studies were found that met inclusion criteria. Data were extracted and statistical analysis was carried out generating forest plots. Results. Non-selective NSAIDs showed a significant decrease in the odds for forming HO after THA (odds ratio (OR) -1.35, confidence interval (CI) -1.83 to -0.86) when compared with placebo. Selective NSAIDs also showed a significant decrease in the odds for forming HO after THA when compared with placebo (OR -1.58, CI -2.41 to -0.75). When comparing non-selective NSAIDs with selective NSAIDs, there was no significant change in the odds for forming HO after THA (OR 0.22, CI -0.36 to 0.79). Conclusion. Our meta-analyses of all available data suggest that both non-selective and selective NSAIDs are effective HO prophylaxis and can be used routinely after THA for pain control as well as prevention of HO. Indomethacin may serve as the benchmark among non-selective NSAIDs and celecoxib among selective NSAIDs. There was no difference in the incidence of HO between non-selective and selective NSAIDs, allowing physicians to choose either based on the clinical scenario and patient-specific factors.

Introduction. The utility and yield of the current practice of routine screening of asymptomatic patients after primary total hip arthroplasty (THA) and total knee arthroplasty (TKA) is unclear. The purpose of this prospective survey study was to determine the utility of the routine on year follow up visit primary THA and TKA. Methods. We prospectively enrolled all patients undergoing primary THA and TKA. At one-year follow-up, patients were asked to complete a survey that asked about satisfaction with the and if they thought the visit was worthwhile. Surgeons also completed a survey which asked if any intervention was done, if any problems were diagnosed/avoided, and if the visit was worthwhile. Data was analyzed and compared between patients and surgeons, and was also compared to the need for any additional interventions. Results. Between October 2017 and June 2018, 512 patients underwent primary THA or TKA. Of these, passive one-year follow-up was obtained in 195 (38%). The final cohort consisted of 195 patients; 102 THAs and 94 TKAs with mean follow-up of 378 days (range, 276–480 days). Patients reported a mean 4.64 rating when asked if the visit was worthwhile (5-point scale, 1=not worthwhile, 5=very worthwhile). No interventions were performed or ordered at 56.3% of visits. Physicians reported that complications were avoided because of the visit at 23.03% of visits and 66.8% of visits were worthwhile (yes/no). 49.44% of visits where no intervention was ordered were rated as worthwhile, whereas 90.3% of visits with interventions ordered were rated as worthwhile. Conclusions. Patients generally thought that their follow up visit was worthwhile, even when no intervention was ordered or issue was addressed. In the visits without any interventions, over half of physicians thought the visit was not worthwhile. Surgeons may consider restricting their one year postoperative visits to symptomatic patients only. For any tables or figures, please contact the authors directly

Introduction. Meaningful clinical improvement as demonstrated through patient-reported outcome measures (PROMs) are increasingly used to evaluate success of total hip arthroplasty (THA) procedures. This patient perspective can provide a full picture when used with clinical data to best evaluate surgical outcomes. Methods. All primary THA procedures reported to the American Joint Replacement Registry from 2012–2018 with linked pre-operative and 1-year post-operative functional or anatomical PROMs were included. The achievement of minimal clinically-important difference (MCID) was calculated using the distribution method. Logistic regression models with covariate adjustment for patient demographics, American Society of Anesthesiologists (ASA) score, and body mass index (BMI) were constructed to identify associations with PROMs. Results were analyzed based on hospital size (small, medium and large) and teaching type (non-teaching, minor and major) based on the American Hospital Association Survey (2015). Results. There were 3,952 THA with pre-operative and 1-year post-operative PROMs. The five types of PROMs collected include: HOOS (n=731), HOOS Jr. (n=295), PROMIS-10 (n=1,074), SF-36 (n=976), VR-12 (1,262). The average age was 66.3±10.5 years, and the majority were female (54.7%). 53.1% of THA patients achieved MCID. Age and gender were statistically significant, while ASA score and BMI classification were not. As age increased by 1 year, the odds of achieving MCID increased 0.8% (OR 0.992, 95%CI 0.984, 0.999) and a minor versus major teaching hospital was 20.8% less likely to achieve MCID (p<0.04). While small hospital sizes had significantly fewer linked PROMs (6.5% of all linked PROMs), only 44.5% achieved MCID compared to medium (52.3%) and large (54.5%) hospitals (p<0.02). Conclusion. Older patient age, major teaching hospitals, and large hospitals achieved higher levels of MCID after THA. Identifying patients that are less likely to achieve MCID can aid physicians by determining patients at risk for poor outcomes, then guiding patient expectations and providing patient-centered care.

Aims

Using data from the Hip Fracture Evaluation with Alternatives of Total Hip Arthroplasty versus Hemiarthroplasty (HEALTH) trial, we sought to determine if a difference in functional outcomes exists between monopolar and bipolar hemiarthroplasty (HA).

Aims

Hip dysplasia (HD) leads to premature osteoarthritis. Timely detection and correction of HD has been shown to improve pain, functional status, and hip longevity. Several time-consuming radiological measurements are currently used to confirm HD. An artificial intelligence (AI) software named HIPPO automatically locates anatomical landmarks on anteroposterior pelvis radiographs and performs the needed measurements. The primary aim of this study was to assess the reliability of this tool as compared to multi-reader evaluation in clinically proven cases of adult HD. The secondary aims were to assess the time savings achieved and evaluate inter-reader assessment.

Aims

Developmental dysplasia of the hip (DDH) describes a pathological relationship between the femoral head and acetabulum. Periacetabular osteotomy (PAO) may be used to treat this condition. The aim of this study was to evaluate the results of PAO in adolescents and adults with persistent DDH.

Aims

Osteoporosis is common in total hip arthroplasty (THA) patients. It plays a substantial factor in the surgery’s outcome, and previous studies have revealed that pharmacological treatment for osteoporosis influences implant survival rate. The purpose of this study was to examine the prevalence of and treatment rates for osteoporosis prior to THA, and to explore differences in osteoporosis-related biomarkers between patients treated and untreated for osteoporosis.

Aims

Avascular femoral head necrosis in the context of gymnastics is a rare but serious complication, appearing similar to Perthes’ disease but occurring later during adolescence. Based on 3D CT animations, we propose repetitive impact between the main supplying vessels on the posterolateral femoral neck and the posterior acetabular wall in hyperextension and external rotation as a possible cause of direct vascular damage, and subsequent femoral head necrosis in three adolescent female gymnasts we are reporting on.

Aims

Transfusion after primary total hip arthroplasty (THA) has become rare, and identification of causative factors allows preventive measures. The aim of this study was to determine patient-specific factors that increase the risk of needing a blood transfusion.

Introduction. Studies are being done comparing 1-stage vs. 2-stage protocols for PJI. 1-stage protocols take an extended period of time requiring 2 separate preps and sets of instruments in order to ensure optimal sterility. While intraoperative service time is one part of the reimbursement algorithm, reimbursement has lagged behind for single stage treatment. If 1-stage results are acceptable, but not reimbursed appropriately, surgeons may be discouraged from managing PJI in a 1-stage fashion. We ask, “What is the reimbursement and intraoperative service time for 1-stage procedures compared to primary surgery?”. Methods. Relative Value Unit's (RVU's), reimbursement and operative time for 50 PJI procedures were reviewed and compared to 250 primary (1°) THA and 250 primary (1°) TKA by four surgeons. Coding was done per AAOS guidelines. Results. Average work RVU's for 1-stage knees were 19.79 RVU's/hr. vs 23.47 for 1° TKA. Average reimbursement for a 1-stage knee was $2,597.08, with an average intraoperative service time of 259 minutes ($601.60/hr.). Average reimbursement for a 1° TKA was $2,435.00, with an average service time of 100 minutes ($1,461/ hr.). Average work RVU's for a 1-stage hip were 19.57/hr. vs 25.59 for a 1° THA. Average reimbursement for a 1-stage hip was $2,826.17, with an average intraoperative service time of 311 minutes ($545.24/ hr.). The average reimbursement for a 1° total hip was $2,754.71 with an average service time of 104 minutes ($1,589.26/ hr.). Conclusion. While RVUs/hr are similar between primaries and 1-stage procedures, 1-stage procedures for PJI are reimbursed at approximately 1/3 the hourly rate of a primary procedure. This may discourage surgeons from selecting this treatment alternative if studies confirm efficacy. Payers should be encouraged to reimburse physicians commensurate with the intraoperative service time needed to perform a 1-stage procedure as adoption will decrease morbidity and save the healthcare system financially

Aims

This study compares the re-revision rate and mortality following septic and aseptic revision hip arthroplasty (rTHA) in registry data, and compares the outcomes to previously reported data.

Aims

To evaluate how abnormal proximal femoral anatomy affects different femoral version measurements in young patients with hip pain.

Aims

Osteoporosis can determine surgical strategy for total hip arthroplasty (THA), and perioperative fracture risk. The aims of this study were to use hip CT to measure femoral bone mineral density (BMD) using CT X-ray absorptiometry (CTXA), determine if systematic evaluation of preoperative femoral BMD with CTXA would improve identification of osteopenia and osteoporosis compared with available preoperative dual-energy X-ray absorptiometry (DXA) analysis, and determine if improved recognition of low BMD would affect the use of cemented stem fixation.
