Aim: To evaluate 90-day episode-of-care (EOC) resource consumption in robotic-assisted total hip arthroplasty (RATHA) versus manual total hip arthroplasty (mTHA). Methods: THA procedures were identified in Medicare 100% data. After propensity score matching 1:5, 938 RATHA and 4,670 mTHA cases were included. 90-day EOC cost, index costs, length of stay and post-index rehabilitation utilization were assessed. Results: RATHA patients were significantly less likely to have post-index inpatient rehabilitation or skilled nursing facility admissions and used fewer home health agency visits, compared with mTHA patients. Total 90-day EOC costs for RATHA patients were found to be US$785 less than those of mTHA patients (p = 0.0095). Conclusion: RATHA was associated with an overall lower 90-day EOC cost when compared with mTHA. The savings associated with RATHA were driven by reduced utilization and cost of post-index rehabilitation services.

Abstract The incidence of hip fractures in patients with Alzheimer’s disease and related dementias (ADRD) is 2.7 times higher than it is in those without ADRD. However, there are no standardized post-acute transition models for patients with ADRD after hip fracture. Additionally, there is a lack of knowledge on how post-acute transitions vary by race/ethnicity. Using 100% Medicare data (2016-2017) for 120,179 older adults with ADRD, we conduct multinomial logistic regression, to examine the association between race and post-acute discharge locations (proportion discharged to skilled nursing facility [SNF], inpatient rehabilitation facility [IRF], and Home with Home Health Care [HHC]), after accounting for patient characteristics. Compared to non-Hispanic Whites, Hispanics have a significantly lower odds ratio for discharge to HHC 0.62 (95%CI=0.53-0.73), IRF 0.44 (CI=0.39-0.51), and SNF 0.26 (CI=0.23-0.30). Improving care in patients with ADRD and reducing racial and ethnic disparities in quality of care and health outcomes will be discussed.

Cup Positioning

AbstractAcetabular component malpositioning is a frequent cause of complications in total hip arthroplasty including instability, increased wear, osteolysis, impingement, and revision surgery. Recently, robotics and navigation have been introduced to improve cup positioning in total hip arthroplasty. The purpose of this study was to compare the accuracy of postoperative acetabular component positioning using MAKO robotic-assisted versus manual acetabular component placement. A consecutive series of 100 total hip replacements were performed in 100 patients. The first 50 were performed using manual techniques, while the second 50 were performed using MAKO-guided acetabular component placement. Postoperative anteroposterior pelvis radiographs were used to determine the postoperative anteversion and inclination of the cup relative to the goal of 15 and 45°, respectively. In the manual group, the average anteversion and inclination was 14.3 and 44.2°, respectively, with 28% within 5° and 82% within 10° of the goal alignment, respectively. In the robotic group, the average anteversion and inclination was 15.1 and 45.6°, respectively, with 54 and 88% within 5 and 10° of the goal alignment, respectively. This equated to a statistically significant improvement in the number of acetabular components placed within 5° of the target alignment with the use of robotic guidance (p = 0.0142). From the authors' study, they were able to demonstrate a significant improvement in acetabular component alignment with the use of robotic techniques. Additional studies are needed to demonstrate improvement in clinical outcomes as a result of improved accuracy and precision of acetabular component placement.

Aims The aim of this study was to evaluate the accuracy of implant placement when using robotic assistance during total hip arthroplasty (THA). Patients and Methods A total of 20 patients underwent a planned THA using preoperative CT scans and robotic-assisted software. There were nine men and 11 women (n = 20 hips) with a mean age of 60.8 years (sd 6.0). Pelvic and femoral bone models were constructed by segmenting both preoperative and postoperative CT scan images. The preoperative anatomical landmarks using the robotic-assisted system were matched to the postoperative 3D reconstructions of the pelvis. Acetabular and femoral component positions as measured intraoperatively and postoperatively were evaluated and compared. Results The system reported accurate values for reconstruction of the hip when compared to those measured postoperatively using CT. The mean deviation from the executed overall hip length and offset were 1.6 mm (sd 2.9) and 0.5 mm (sd 3.0), respectively. Mean combined anteversion was similar and correlated between intraoperative measurements and postoperative CT measurements (32.5°, sd 5.9° versus 32.2°, sd 6.4°; respectively; R2 = 0.65; p < 0.001). There was a significant correlation between mean intraoperative (40.4°, sd 2.1°) acetabular component inclination and mean measured postoperative inclination (40.12°, sd 3.0°, R2 = 0.62; p < 0.001). There was a significant correlation between mean intraoperative version (23.2°, sd 2.3°), and postoperatively measured version (23.0°, sd 2.4°; R2 = 0.76; p < 0.001). Preoperative and postoperative femoral component anteversion were significantly correlated with one another (R2 = 0.64; p < 0.001). Three patients had CT scan measurements that differed substantially from the intraoperative robotic measurements when evaluating stem anteversion. Conclusion This is the first study to evaluate the success of hip reconstruction overall using robotic-assisted THA. The overall hip reconstruction obtained in the operating theatre using robotic assistance accurately correlated with the postoperative component position assessed independently using CT based 3D modelling. Clinical correlation during surgery should continue to be practiced and compared with observed intraoperative robotic values. Cite this article: Bone Joint J 2018;100-B:1303–9.

Abstract Background An inpatient hospital stay of up to 10 days after total hip arthroplasty (THA) is still common in Germany, mostly followed by inpatient rehabilitation. Internationally already widespread concepts for enhanced recovery are increasingly gaining popularity in Germany. Objectives The presentation of content and results of a newly implemented enhanced recovery concept in THA. Materials and Methods In this single-center, prospective observational study of a consecutive patient collective of a single surgeon, between January 2016 and July 2016, 103 short-stem THA patients were enrolled and treated using a newly introduced enhanced recovery concept. After 6 weeks and 6 months clinical examination was performed regarding function, pain, satisfaction and possible complications. Results The goal of discharge on day 4 after operation was reached in 61.2% of the patients with a mean postoperative inpatient stay of 4.9 days. After 6 weeks and 6 months respectively, excellent clinical results were achieved with high patient satisfaction. The complication rate was found to be low. Mean hemoglobin concentration decreased by 2.1 g/dl. A fissure of the femur below the implant healed conservatively applying no weight bearing for a total of 6 weeks. A pulmonary embolism that occurred during rehabilitation was also successfully treated. After 6 months one case showed a bursitis trochanterica. Conclusions Inpatient length of stay can be reduced by enhanced recovery concepts without increasing the risks to patients. Thus, in Germany these concepts will be applied increasingly.
