Combined unicompartmental knee arthroplasty and ACL reconstruction for medial knee osteoarthritis complicated by ACL insufficiency: superior early functional recovery with LARS artificial ligament and comparable mid-term results versus autologous tendon.

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
Background: To evaluate the outcomes of fixed-bearing medial unicompartmental knee arthro plasty (UKA) combined with anterior cruciate ligament (ACL) reconstruction using either a LARS artificial ligament or autologous tendon graft, compared with isolated UKA in ACL-intact knees. Methods: Patients who underwent UKA combined with ACL reconstruction from January 2019 to December 2021 were retrospectively reviewed. They were divided into the LARS group (L-UKA, Results: The mean follow-up was 61.07 ± 3.90 months. Baseline characteristics were comparable among the three groups. At final follow-up, ROM, KSS and OKS improved significantly in all groups compared with preoperative values ( Conclusion: UKA combined with ACL reconstruction using either LARS artificial ligament or autologous tendon graft effectively corrected ATT and achieved mid-term outcomes comparable to isolated UKA. LARS avoided donor-site morbidity and provided better early functional recovery, although its long-term safety requires further validation.
