Key Takeaway: The ROSA® Knee System produces more accurate and reproducible bone resection angles and levels compared to conventional instrumentation.
Key Takeaway: Robotic-assisted total knee arthroplasty with the ROSA® Knee System may reduce the need for unnecessary soft tissue releases to achieve coronal alignment to the mechanical axis in total knee arthroplasty.
Key Takeaway: The [ROSA Knee System] is accurate in terms of the coronal alignment and bone resections. [This study] …shows that the accuracy previously reported only in cadavers can also be achieved in patients.
Key Takeaway: The ROSA® Knee System can be adopted rather quickly regarding the initial learning curve. This was measured as the initial cut point for reducing surgical time back to the mean surgical time. Improvements in accuracy compared to manual TKA were seen in the mastered robotic-assisted TKA cases.
Key Takeaway: The ROSA® Knee System improved reproducibility of post-operative alignment in valgus deformities and improved tibial component positioning compared to conventional TKA, suggesting that the ROSA Knee System may be more effective in challenging cases requiring precise alignment and component positioning.
Key Takeaway: The ROSA Hip® System is associated with a brief initial learning curve of 12 cases, with the most significant improvements in surgical efficiency realized during acetabular cup placement.
Key Takeaway: The ROSA Hip® System shows no clinically significant increase in radiation exposure to the patient compared to manual approaches. In addition, when compared to the literature, the radiation exposure is less than that of CT-based robotic approaches.
Key Takeaway: The ROSA Hip® System demonstrated more accurate acetabular cup positioning and resulted in fewer outliers compared to manual THA.

Key Takeaway: The ROSA Hip® System allows for accurate cup placement independent of obesity status, minimizing the risk of over-abducted “open” cups when using a minimally invasive direct anterior approach for THA.
Key Takeaway: The ROSA Hip® System standardizes the THA procedure by reducing differences in placement of left or right acetabular cups, which may lead to more homogenous outcomes across different surgical scenarios.
Key Takeaway: Robotic-assisted total hip arthroplasty with the ROSA Hip® System leads to lower treatment costs and improved utility through at least 5-years post-operative.
Key Takeaway: ONE Planner® Hip has a similar high level of accuracy as the predicate software supporting its use for preoperative planning with fluoroscopy-based robotic-assisted THA.
Key Takeaway: Signature ONE planner and patient-specific guides were significantly more accurate (P=.01) for the combined vectors of version and inclination compared to conventional instruments.
Key Takeaway: This study provides a unique and valuable visual aid to assist with patient counseling and setting perioperative expectations.
Patients can be counseled that the greatest proportional improvement in PROMs is within one month after THA, while function surpasses pre-operative baselines by three-months, and gait quality may not improve until after one-year. This can help set realistic expectations and target interventions toward patients deviating from the norm.
Key Takeaway: This study demonstrates that the use of a smartphone-based care platform after primary knee arthroplasty resulted in significantly less visits to physiotherapy and the ED when compared to the control group.
Implementation of this smartphone/smart watch care platform showed similar outcomes to traditional care models at 1 year postoperative. Traditional physiotherapy and ED visits were seen at much lower rates in this cohort, demonstrating a lower usage of health care resources. This application could assist in alleviating the need for health care dollars by reducing postoperative costs, enhancing communication across the health care team, and permitting such resources to be more properly distributed.
Key Takeaway: Patients found remote monitoring with mymobility easy to use, increased motivation, and recommend it to other patients undergoing lower extremity arthroplasty.
Remote monitoring technologies for THA, TKA, and UKA provide patients motivation to conduct their rehabilitation programs, and patients would recommend it to other patients undergoing similar procedures. The THA patients felt that these technologies could eventually even completely replace in-person rehabilitation programs, but all patients recommend a combination of technology and in-person rehabilitation postoperatively. This study showed an overwhelmingly positive experience of patients utilizing remote monitoring rehabilitation technologies.
Key Takeaway: Equivalent outcomes and significantly fewer PT visits with mymobility for TKA/PKA
The purpose of this study was to determine the non-inferiority of a smartphone-based exercise educational care management system after primary knee arthroplasty compared with a traditional in-person physiotherapy rehabilitation model. The data found that mymobility is clinically non-inferior to the standard of care for all outcomes. mymobility users demonstrated a significant reduction of physical therapy utilization post-operatively. Further, mymobility users trended lower on ED visits than control group, though not statistically significant. This platform could aid in decreasing post-operative costs, while improving patient engagement and communication with the healthcare team.
Key Takeaway: Equivalent outcomes and significantly fewer PT visits with mymobility for THA
The purpose of this study was to determine the non-inferiority of a smartphone-based exercise educational care management system after primary total hip arthroplasty compared with a traditional in-person physiotherapy rehabilitation model. The data found that mymobility is clinically non-inferior to the standard of care for all outcomes. mymobility users demonstrated a significant reduction of physical therapy utilization post-operatively. Further, mymobility users trended lower on ED visits than the control group and hospital readmissions, though not statistically significant. This platform could aid in decreasing post-operative costs, while improving patient engagement and communication with the healthcare team.
Key Takeaway: mymobility enables remote gait quality measurements
The purpose of this study was to assess the recovery of gait quality following primary total hip and knee arthroplasty using a smart-phone based care management platform. The recovery curves reflect previous curves captured by traditional gait analysis methods as well as functional and patient reported outcome scores. Capturing real-world gait quality metrics through the phone may provide further insights into objective recovery data not captured by traditional in-clinic assessments.
Key Takeaway: Objective and reliable data with mymobility
The purpose of this study was to characterize the recovery of physical activity following knee arthroplasty by means of step counts and flight counts (flights of stairs) measured using a smart-phone based care platform. This data demonstrated a recovery curve similar to previously reported curves for patient reported outcome measures in the arthroplasty arena. Patients and surgeons may use this information to help set goals for recovery following total and partial knee arthroplasty using objective activity measures.
Key Takeaway: mymobility can be integrated with ROSA Knee to passively collect data throughout the episode-of-care. Associations between intra-operative decisions regarding laxity and post-operative outcomes were identified.
There were higher step counts at six-weeks post-operatively in knees with >2mm increased laxity in both the lateral compartment in extension and medial compartment in flexion (p<0.05). Knees balanced in flexion within <0.5mm had higher KOOS JR scores at six-weeks post-operative (p=0.034) compared to knees balanced within 0.5 – 1.5mm. Knees with laxity balanced between 0.5 and 1.5 mm and those with more than 1.5 mm of laxity between medial and lateral compartments in extension had significantly greater step counts at six-weeks. The study has a relatively small sample size (n=131).
The focus of this paper was on the feasibility of data collection throughout the episode of care. These associations are intriguing, and the clinical relevance needs further investigation.
Key Takeaway: The current study demonstrates that the HipXpert system with the HipXpert 3D Display and Anchoring Application can be used to successfully achieve accurate implant orientation in the acetabulum.
The study tested the clinical accuracy of the HipXpert system with the HipXpert 3D Display and Anchoring Application in a cadaveric study. It demonstrates that the HipXpert system with the HipXpert 3D Display and Anchoring Application resulted in implant orientation accuracy of less than 5 degrees error for both anteversion and inclination for all 47 screw implantations using both the anterior and lateral tools.
Key Takeaway: Microsoft HoloLens 2 was used for unplanned remote assistance for telesurgical support.
This case study demonstrates the ability to use the HoloLens 2 with Microsoft Dynamics 365 Remote Assist Software to provide immediate telesurgical support by an industry representative, the PM, to the operating surgeon approximately 100 km apart. The data is transferred via an encrypted and secured cloud-based program and provided the PM a real-time surgeon viewpoint of the operating theatre, including direct line of site to the operative knee, the operating instruments, and even the surgeon’s hands.
Key Takeaway: 6-week post-operative recovery trends were associated with 12-week post-operative recovery trends for gait and range of motion metrics.
Key Takeaway: Objective functional improvement is likely not captured in the patient’s perceived recovery. Thus, a holistic approach to monitoring recovery should include passively collected gait metrics such as what is offered by Persona IQ The Smart Knee.
Key Takeaway: Data from Persona IQ The Smart Knee shows high data collection compliance, providing baseline free-living gait metrics after total knee arthroplasty, which may be useful in comparisons of individual patients, cohort comparisons, and in determining minimally clinically important differences in future studies.
Key Takeaway: Kinematic data is intended as an adjunct to other physiologic measurement tools. Analysis of gait data may allow for better understanding of differences in recovery and the ability to set goals within different patient groups.
Key Takeaway: Objectively measured functional recovery can act as an excellent supplement to the Patient Report Outcome Measures (PROMs) typically collected for monitoring patient outcomes following Total Knee Arthroplasty.
