Intraoperative management of pre-operative flexion contractures using robotic-assisted total knee arthroplasty.
Article in Journal of experimental orthopaedics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Purpose: To determine how the severity of preoperative flexion contracture influences intraoperative resection strategy, final balance, postoperative range of motion and Knee Injury and Osteoarthritis Outcome Score for Joint Replacement (KOOS-JR) outcomes in robotic-assisted total knee arthroplasty (RA-TKA). Methods: This retrospective cohort study included primary imageless RA-TKAs performed using the RObotic Surgical Assistant (ROSA) Knee System. Knees with preoperative flexion contracture were categorized as >0° to 5°, >5° to 10° and >10°. Preoperative standing full-length radiographs were used to measure hip-knee-ankle angle. Intraoperative resection, gap and balance data were collected. Preoperative and 6-week postoperative range-of-motion data were obtained from medical records, and KOOS-JR scores were collected preoperatively and at 1 year. Results: In total, 263 knees with preoperative flexion contracture were included, with final intraoperative outcomes available for 227 knees. Distal medial femoral resection increased with contracture severity (9.0 ± 1.3, 9.3 ± 1.2 and 9.8 ± 0.8 mm in the >0°-5°, >5°-10° and >10° groups; Conclusions: Preoperative flexion contracture was associated with minor differences in intraoperative resection strategy, particularly distal medial femoral resection. Final intraoperative balance and early outcomes were similar across flexion contracture groups. Level of Evidence: Level III, retrospective cohort study.
