This systematic review compared robotic-assisted total knee arthroplasty (RA-TKA) with conventional manual TKA in human studies with at least 12 months of follow-up. Twenty-three studies met the criteria, most providing level II or III evidence. RA-TKA was associated with improved component alignment and knee balance, reduced blood loss, and soft-tissue preservation, alongside lower postoperative pain and opioid use. Complication rates were broadly similar, although findings varied, and available studies generally reported comparable medium- and long-term implant survival. The review concludes that long-term advantages, particularly for complications and implant durability, remain uncertain.
Key findings
- Twenty-three studies were included; most were rated as level II or III evidence.
- RA-TKA was associated with improved component alignment and knee balance, reduced blood loss, and soft-tissue preservation.
- The review linked these findings with lower postoperative pain and reduced opioid consumption.
- Complication rates were similar overall, and most studies reported comparable medium- and long-term implant survival, but results and survivorship data were limited.
Why it matters
The review suggests that robotic assistance may improve several perioperative and technical outcomes, but these advantages have not established better long-term durability or fewer complications. Distinguishing short-term improvements from sustained patient benefit is important when interpreting comparative evidence for knee arthroplasty and highlights the need for longer follow-up.
What to keep in mind
Most included studies were level II or III evidence; complication findings varied, and implant-survivorship data were limited.
