History of anterior cruciate ligament reconstruction does not increase the risk of postoperative complications following total knee arthroplasty: a systematic review and meta-analysis.
Synthesis in International orthopaedics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundTotal knee arthroplasty (TKA) is the gold-standard treatment for end-stage osteoarthritis (OA), offering substantial pain relief and functional improvement. With the rising incidence of sports-related injuries and advancements in anterior cruciate ligament reconstruction (ACLR) techniques, an increasing number of patients undergoing TKA have a history of ACLR. However, the impact of prior ACLR on postoperative complications and functional recovery after TKA remains controversial.
methodsThis study performed a systematic search across four databases, including case-control and cohort studies reporting on the outcomes of TKA following ACLR. Primary endpoints included infection, reoperation, prosthesis revision, thrombosis, and postoperative stiffness following manual release under general anaesthesia, with results compared to those of a control group of patients receiving TKA for primary OA. Secondary endpoints were operative time and postoperative range of motion in both flexion and extension. This study was registered in PROSPERO under the registration number CRD420250635375.
resultsA total of nine studies were included in this study, involving 4381 participants, with 1112 undergoing TKA with ACLR history and 3269 undergoing TKA for primary OA. This study showed that the operative time of TKA after ACLR was significantly extended (P < 0.01), but there was no significant difference in postoperative infection, reoperation, prosthesis re-revision, thrombus, postoperative stiffness following manual release under general anaesthesia, and range of motion in both flexion and extension.
conclusionsAlthough the operation time of TKA after ACLR was extended, the complication rate and postoperative functional recovery of TKA were not significantly different from those of primary OA patients. This study provided an evidence-based basis for preoperative assessment and patient management.
