Comparison of Patient-Reported Outcome Measures Between Robotic-Assisted and Manual Total Hip Arthroplasty: A Systematic Review with a Minimum 2-Year Follow-Up.

Since robotic THA is a relatively new procedure, there is a paucity of high-quality research evaluating long-term PROMs, and as such this study aimed to compare the long term outcomes in robotic and manual THA. To systematically review the literature comparing mid- to long-term patient-reported outcome measures (PROMs) between robotic-assisted and manual THA. This study focused specifically on full-body text of studies comparing robotic and manual THA and comparing PROMs with a minimum of 2 years follow-up. Inclusion criteria were studies comparing robotic THA and manual THA and showing at least 1 PROMs with a minimum follow-up period of 2 years. Five studies reported higher scores in 2-year follow-up for patient undergone robotic surgery. In addition, most studies did not show significant difference in dislocation nor revision rate between robotic and manual THA. Six studies assessed limb-length discrepancy using radiographic measurements and found no evidence of superior outcomes in either group. Based on the current evidence, this review identified evidence suggesting a trend toward better PROMs in patients operated on robotically. However, there was not enough evidence to conclude a correlation between lower risks for post-operative complications, revisions, and dislocations and robotic surgery.
