Overall, the use of rTKA did not provide any benefits in functional, quality of life, and satisfaction scores after six months compared to mTKA in patients undergoing TKA for knee osteoarthritis. However, the rTKA group showed significantly better pain scores after 2 and 6 months. The results of this trial were limited by a short follow-up.
Study Summary
100 patients undergoing total knee arthroplasty (TKA) for end-stage osteoarthritis were randomized to receive either robotic TKA (rTKA; n=50) or manual TKA (mTKA; n=50). The primary outcomes of interest were the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores with a focus on pain, function, stiffness subscales, and total scores. The secondary outcomes of interest included the Oxford Knee Score (OKS), Forgotten Joint Score (FJS), EuroQol 5D (EQ-5D), EQ-5D Visual Analog Scores (VAS) pain scores, and the incidence of any complications. WOMAC pain was significantly better in the rTKA group at 2 and 6 months, whereas, all other outcomes were similar between the two groups. The incidence of complications also were comparable between the two groups. Four patients, however, reported unexplained ongoing knee pain after 6 months in the mTKA group.
