According to news originating from Chengdu, People' s Republic of China, by NewsRx correspondents, research stated, "We investigated the advantages of robotic arm-assisted total knee arthroplasty (raTKA) over con ventional manual TKA (cmTKA) by comprehensively comparing patients who received raTKA and cmTKA in terms of postoperative pain, function, imaging assessment, an d trauma to the body. This study investigated the efficacy and safety of raTKA i n patients using the YUANHUA-TKA system." Financial support for this research came from National Natural Science Foundatio n of China. Our news journalists obtained a quote from the research from the West China Hosp ital of Sichuan University, "In a prospective, randomized single-blind trial, 60 patients undergoing primary unilateral TKA from October 2020 to December 2020 w ere randomly assigned to either raTKA or cmTKA. Clinical evaluation, including t he time of osteotomy and prosthesis model testing, the total operation time, the visual analogue scale at rest, VAS in motion, opioid consumption, white blood c ell count, neutrophil ratio, erythrocyte sedimentation rate, C-reactive protein (CRP), passive and active range of motion (pROM, aROM), Western Ontario and McMa ster Universities Arthritis Index (WOMAC [stiffness, pain, an d function]) score, gait analysis, keen society score (KSS), adverse events, and blood loss were collected by the project nurse, as well as t he imaging evaluation, including the lateral tibia component angle (LTC), fronta l femoral component angle, frontal tibia component angle (FTC), lateral femoral component angl, and hip-knee-ankle angle (HKA). The student t-test (or the Wilco xon signed-rank test) and the ch - test (or the Fisher exact test) were used to d etermine differences in categorical variables. No significant difference was fou nd between the two groups in pain throughout the whole follow-up period. On the third day postoperatively, the erythrocyte sedimentation rate in the cmTKA group was significantly higher (p = 0.02), as well as the CRP (p = 0.04). No signific ant difference was found in the WOMAC stiffnes score or pROM. However, the aROM and the flexion range when walking (FRW) were significantly better in the raTKA group throughout the trial (p <0.05). The KSS at the 1-mon th follow-up and the WOMAC function score at the 1-year follow-up were both sign ificantly better in the raTKA group (p <0.05). The HKA and the LTC in the raTKA group closer to the ideal angle, and the difference betwee n the groups was significant (p <0.05). The total operatio n time of the raTKA group was significantly longer (p = 0.001). The intraoperati ve blood loss had no significant difference in the two groups."
