R and om-effects meta-analyses showed that post-operative functional outcomes were comparable between active robotic and conventional total hip and knee arthroplasty at the short- , medium- and long-term follow-up .
Conclusions This systematic and meta-analyses indicates that functional outcomes for patients undergoing active robotic total hip and knee arthroplasty were comparable to conventional surgery .
Whether semi-active or active robotic hip or knee arthroplasty is effective in improving post-operative pain , quality of life and satisfaction with surgery is unclear .
Purpose The purpose of the study is to determine the effectiveness of semi-active and active robotic hip and knee arthroplasty on post-operative patient-reported outcomes of function , pain , quality of life and satisfaction with surgery .
Primary and Revision Total Hip Replacement Using the Robodoc® System
The ROBODOC ® system was design ed to address potential human errors in performing cementless total hip replacement . The system consists of a preoperative planning computer workstation ( called ORTHODOC ) and a five-axis robotic arm with a high speed milling device as an end effector . The combined experience of the United States Food and Drug Administration multicenter trial and the German postmarket use of the system are reported . The United States study is controlled and r and omized with 136 hip replacements performed at three centers ( 65 ROBODOC ® and 62 control ) . Followup was 1 year on 127 hip replacements and 2 years on 93 hip replacements . No differences were found in the Harris hip scores or the Short Form Health Survey outcomes question naire . Length of stay also was not different , but the surgical time and blood loss were greater in the ROBODOC ® group . This was attributed to a learning curve at each center . Radiographs were evaluated by an independent bone radiologist and showed statistically better fit and positioning of the femoral component in the ROBODOC ® group . Complications were not different , except for three cases of intraoperative femoral fracture in the control group and none in the ROBODOC ® group . The German study reports on 858 patients , 42 with bilateral hip replacements and this includes 30 revision cases for a total of 900 hip replacements .  The Harris hip score rose from 43.7 to 91.5 . In these cases the surgical time declined quickly from 240 minutes for the first case to 90 minutes . No intraoperative femoral fractures occurred in 900 cases . Other complications were comparable with total hip replacements performed using conventional techniques . The ROBODOC ® system is thought to be safe and effective in producing radiographically superior implant fit and positioning while eliminating femoral fractures
