Comparative outcomes of robot-assisted versus conventional TKA in rheumatoid arthritis patients.

ABSTRACT:

Objective

To evaluate the surgical outcomes of RA-TKA compared to C-TKA in patients with rheumatoid arthritis.

Methods

A retrospective study was conducted at the PLA General Hospital, enrolling 239 rheumatoid arthritis patients who underwent either robot-assisted TKA or conventional TKA, with 102 and 187 patients in the RA-TKA and C-TKA groups, respectively. All patients were followed up 2 years. Follow-up indicators included KSS and WOMAC scores, single-leg standing time(SLST), and knee joint range of motion. The patients were evaluated at 2 weeks, 3 months, 6 months, 1year and 2 years postoperatively. All data were prospectively collected.

Results

At 2 weeks postoperatively, the RA-TKA group showed superior KSS symptom scores (9.23 ± 3.38 vs. 10.79 ±  2.67 p =  0.00
