Comparison of Robotic-Assisted Versus Conventional Total Knee Arthroplasty: A Systematic Review and Meta-Analysis

Robotic-assisted total knee arthroplasty (RTKA) is an emerging alternative to conventional total knee arthroplasty (CTKA) with uncertain effectiveness. This systematic and meta-analysis aims to compare clinical and radiological outcomes between RTKA and CTKA.

52 studies were included (randomised controlled trials and observational cohorts). Outcomes compared were alignment (Hip-Knee-Ankle angle, femoral/tibial component angles), Patient Reported Outcome Measures (PROMs), operative time, length of stay (LOS), blood loss, and complications. Data were pooled using random-effect models, with heterogeneity assessed via I2 statistics using R.
