Below is an example of a clinical study that is pure "propaganda". It was put together by well-meaning KOLs and well-meaning professionals in a device company. (Note: not to pick on ZB or Rosa, because there are thousands of examples like this in orthopedics.)
Where are the controls? Why isn't there a significant sample size? Where is the scientific method?
Our beloved orthopedics industry can do better than this.
Study confirms high accuracy of a new robotically assisted technique for total knee arthroplasty (ZB landing page)
Robotic Total Knee Arthroplasty (TKA) has gained popularity over the last few years for improving the accuracy of implant positioning and reducing issues with limb alignment when compared with a conventional jig-based TKA. Pain, instability and limitation of the range of motion are the most commonly reported symptoms among unsatisfied patients. The major causes of unsuccessful TKA are inadequate alignment and errors in balancing.
The aim of the study was to evaluate the accuracy of the robotically assisted method to see if outcomes for patients could be improved. 75 patients underwent total knee arthroplasty using a new, robotic system (ROSA® Knee S...
