Key Takeaways: 35% relative reduction in early revision rates
The survivorship reported within the AOANJRR of Persona® Knee implants combined with early data from the ROSA Knee System is promising. The CPR for Persona Knee CR and PS bearings is 1.9 (95% CI, 1.6 – 2.2) at five years, compared to a CPR of 3.4 (95% CI, 3.4-3.5) for the same follow-up time with all other total knees. The revisions/100 observation years was 0.39 (95% CI, 0.14 – 0.86) for robotic assisted TKA using the Persona knee compared to 0.60 (95% CI, 0.52– 0.68) without robotic assistance for the same implants. This demonstrates a relative reduction in revisions of 35% when robotic assistance was used.
Key Takeaways: ROSA knee is easy to integrate with minimal learning curves
The Robotic Surgical Assistant (ROSA, Zimmer Biomet, Warsaw, IN) allows for the surgeon to maintain full autonomy and control of operative decision-making while providing precise, objective, and real-time data for intraoperative adjustments, thus allowing the surgeon to both individualize and reproduce the Total Knee Replacement.
Key Takeaways: ROSA Knee facilitates complex cases
The ROSA® Total Knee System allowed precise intraoperative adjustments, as demonstrated by these cases, and is a promising step towards more personalized total knee arthroplasty made possible by utilizing real-time objective measures.
Key Takeaways: X-Atlas™ imaging technology could effectively predict implant sizing.
The X-Atlas™ imaging technology proved to be accurate to reconstruct a 3D bone model and results have shown that it might provide benefits to surgeons seeking improved planning and precision without the problems of obtaining 3D imaging.
Key Takeaways: ROSA Knee uses same highly-accurate robotic arm as ROSA Brain.
Intrinsic characteristics of the six degrees of freedom (DOF) anthropomorphic industrial robotic arm combined with specific features designed by Zimmer Biomet explain why it has chosen this kind of technology for use in surgical procedures. The robotic platforms designed by Zimmer Biomet offer a state-of-the-art robotic experience for patients, physicians and hospitals.
Key Takeaways: ROSA Knee is more accurate than conventional instrumentation
The results of this cadaveric study demonstrate that surgeons using this novel TKA robotic system can achieve bone resections with a higher level of accuracy and less alignment outliers compared to a conventional procedure.
Key Takeaways: ROSA Knee is highly accurate
The results of this cadaveric study demonstrated that surgeons using this new surgical robot in total knee arthroplasty can perform highly accurate bone cuts to achieve the planned angles and resection thickness as measured using conventional navigation.
Key Takeaways: 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 Takeaways: 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 Takeaways: 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 Takeaways: 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 Takeaways: Older adults adopt technology.
Older adults are demonstrating a continued and significant adoption of technology. Moreover, baby boomers are increasingly eager to have their health care needs managed through a combination of technology and traditional health care.
Key Takeaways: First-ever example of identifying treatment trends with combination of ROSA and mymobility data in a commercial database
The purpose of the study was to demonstrate the feasibility of passively collecting objective, anonymized data from a commercially available smartphone-based care management platform (sbCMP) and robotic assisted total knee arthroplasty (raTKA). The use of passively collected objective measures in a commercial database across the episode of care was feasible and demonstrated associations between intraoperative and post-operative metrics.
This is the first integrated data collection and reporting platform to demonstrate these measures in a commercial population.
