[A cadaveric experimental study on domestic robot-assisted total knee arthroplasty].
Article in Zhongguo xiu fu chong jian wai ke za zhi = Zhongguo xiufu chongjian waike zazhi = Chinese journal of reparative and reconstructive surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveTo simulate and validate the performance, accuracy, and safety of the Yuanhua robotic-assisted total knee arthroplasty system (YUANHUA-TKA) through cadaver-based experiment, thus optimizing the robotic system for the future human clinical application.
methodsSix unilateral adult cadaver specimens of the lower limbs were scanned by three-dimensional CT before the experiment, and then the three-dimensional models of femur and tibia were obtained by using the preoperative software of YUANHUA-TKA system, so as to plan the type of prosthesis implant, the osteotomy volume and osteotomy angles [hip-knee-ankle angle (HKA), coronal frontal femoral component (FFC) and frontal tibial component (FTC)], the ideal value of HKA was set to 180°, and of FFC and FTC were set to 90°, respectively. The operator could further confirm the osteotomy plan according to the intraoperative situation before osteotomy, and then install the prosthesis after completing the osteotomy in each plane with the assistance of YUANHUA-TKA system. At last, the X-ray films of hip joint, knee joint, and ankle joint were taken and stitched into the full length X-ray film of the lower limb, and HKA, coronal FFC and FTC were measured.
resultsDuring the experiment, YUANHUA-TKA system ran stably. All sections of femur and tibia were smooth and no ligament injury was found. After operation, the HKA was 177.1°-179.7°, FFC was 87.9°-91.4°, and FTC was 87.3°-91.4°, which were within ±3° from the ideal values of preoperative planning.
conclusionThe YUANHUA-TKA system can assist the surgeon to carry out precise osteotomy according to the preoperative planned value, which has a good auxiliary effect for total knee arthroplasty. It is expected to assist joint surgeons to improve the surgical accuracy in clinical application.
