Robotic‐Arm Assisted versus Manual Total Hip Arthroplasty: Systematic Review and Meta‐analysis of Radiographic Accuracy

xlomafota13 shared this article with you from Inoreader Robotic‐Arm Assisted versus Manual Total Hip Arthroplasty: Systematic Review and Meta‐analysis of Radiographic Accuracy Via The International Journal of Medical Robotics and Computer Assisted Surgery Abstract Background We systematically reviewed the radiological outcomes of studies comparing robotic-assisted (RA-THA) and manual total hip arthroplasty (mTHA) . Methods The PubMed, Embase, and Cochrane databases were queried from 1994-2021 for articles comparing radiographic outcomes between RA-THA and mTHA cohorts. A meta-analysis was conducted whenever sufficient data was present for common outcomes. Results Our analysis included 20 articles reporting on 4,140 patients (RA-THA: n=1,228; mTHA: n= 2,912). No differences were demonstrated for acetabular inclination or anteversion. However, RA-THA demonstrated higher rates of cup orientation within the Lewinnek and Callanan safe zones, improved femoral stem alignment, and lower global offset difference (GOD) and limb length discrepancy (all p-values <0.05). Superior femoral canal fill and combined offset were seen among RA-THA patients. Conclusion Our review found that the use of RA-THA yields superior radiographic outcomes compared to mTHA counterparts.
