Results of arthroscopic microfracture treatment for traumatic and non-traumatic osteochondral lesions of the talus: a retrospective cohort study.
Article in BMC musculoskeletal disorders, 2025. 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
backgroundThis study is designed to assess the extent to which the outcomes of arthroscopic microfracture surgery for talus osteochondral lesions (OLTs)-whether of traumatic or atraumatic origin-are influenced by these underlying etiologic factors. Toward this end, it aims to optimise patient selection and treatment plans, thereby enabling the prediction of surgical prognosis.
methodsThis retrospective study included 70 ankles from 70 patients with OLTs, who were treated with microfracture procedures using anterior ankle arthroscopy by orthopaedic surgeons at two different medical centres. Of these cases, 38 were of a traumatic origin (Group 1) and 32 were of a non-traumatic origin (Group 2). The inclusion criteria were adult patients with unilateral, detached and/or displaced lesions located in the medial central region of the talus. Preoperative and final follow-up American Orthopaedic Foot and Ankle Society (AOFAS) and Visual Analogue Scale (VAS) pain scores were compared within and between groups. The rate of return to baseline activity levels was also compared between the various groups. The potential influence of body mass index (BMI) on both etiology and surgical outcome was examined.
resultsThe median follow-up period, as the interquartile range, for all patients was 39 months, ranging from 26 to 54.25 months. Both groups of patients showed significant improvement in their AOFAS and VAS scores postoperatively compared with their preoperative assessment (p < 0.001). Nevertheless, no statistically significant difference was found in the median AOFAS and VAS scores between Group 1 and Group 2 (p > 0.05). After the operation, 66 patients, representing 94.3%, successfully resumed their previous lifestyle, with no difference observed between the two groups (p = 0.392). In addition, the mean BMI in Group 2 was significantly higher than in Group 1 (p = 0.0035).
conclusionArthroscopic microfracture treatment provides similar clinical outcomes in the case of non-traumatic and traumatic OLTs. A high BMI, however, has been recognized as a significant risk factor for the development of non-traumatic OLTs.
