Subchondral bone conditions influence pain in patients with osteochondral lesion of the talus.

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
purposeOsteochondral lesion of the talus (OLT) is characterized by articular cartilage and subchondral bone damage, leading to ankle pain and functional limitations. Some patients experience persistent pain and reduced functionality despite various treatments. Understanding the location and characteristics of pain in OLT may lead to good clinical outcomes. This study aimed to analyze pain characteristics and their relationship with intra-articular pathology in patients with OLT using the Self-Administered Foot Evaluation Questionnaire (SAFE-Q). MATERIALS AND
methodsA retrospective review was conducted on 32 ankles of 29 patients who underwent surgical treatment for stage 3 OLT of Anderson classification. The SAFE-Q scores, patient-reported outcome measures, and Ankle Activity Scores (AAS) were evaluated. The area of the bone marrow lesion on the magnetic resonance imaging, and the Hounsfield unit (HU) values on the computed tomography were measured. In addition, the cartilage condition of the osteochondral fragment and synovitis were scored under arthroscopy. The relationships between pain and these parameters were analyzed.
resultsSignificant positive correlations were observed between pain and pain-related SAFE-Q scores and HU values in the bed of the OLT. No significant correlations were found between the pain scores and lesion size, synovitis, or cartilage condition. The median pain and pain-related subscale score (69.4 points) was used to classify patients into mild and severe pain groups. Severe pain was associated with lower HU values, whereas mild pain was associated with higher HU values.
conclusionsHU values in the bed of OLT are associated with pain severity. Understanding pain mechanisms in OLT can enhance treatment strategies and improve clinical outcomes. LEVEL OF EVIDENCE: 4.
