Unicompartmental knee arthroplasty (UKA) is a feasible alternative to total knee arthroplasty (TKA) for selected patients with severe single-compartment knee osteoarthritis. Robotic-assisted UKA (rUKA) has recently emerged as a complementary tool to ameliorate previous difficulties with manual UKA (mUKA). However, the influence of rUKA compared to mUKA on patient outcomes are still largely unknown. ⋯ In conclusion, unicompartmental knee arthroplasty implants demonstrated comparable survivorship rates whether performed manually or with robotic assistance. However, compared to the manually performed procedure, robotic-assisted unicompartmental knee arthroplasty were found to offer benefits including shorter lengths of hospital stays, decreased postoperative pain scores, and improved functional outcomes.
