Does imageless procedure provide functional results comparable to those of image-based navigation?\n2. Are there differences in postoperative complications patients may experience after RA-TKA with imageless and image-based navigation? Researchers will compare imageless navigation with image-based navigation used in total knee arthroplasty to assess whether imageless navigation is comparable for the treatment of knee osteoarthritis.\n\nParticipants will:\n\n1. Answer survey questions about knee pain and function before RA-TKA.\n2. Undergo RA-TKA with imageless navigation or image-based navigation.\n3. Visit the Clinic after 6 months and 12 months after surgery for checkups and to answer the same survey questions about postoperative knee pain and function.",[81,82,83,84],"Osteoarthritis (OA) of the Knee","Knee Pain Arthritis","Total Knee Arthroplasty (TKA)","Robotic Assisted Arthroplasty",[86,87,88,89,90],"Knee Osteoarthritis","Robotic-Assisted Total Knee Arthroplasty","Patient Reported Outcome Measures","Imageless Navigation","Image-based Navigation","2026-08-11",{"date":93,"type":94},"2026-08-13","ACTUAL",{"date":96,"type":94},"2026-08-06",{"date":98,"type":75},"2029-01",{"name":5,"class":6},1]
