No Evidence That Preoperative Marijuana Use Influences the Success of Hip Arthroscopy for Femoracetabular Impingement in Adolescents and Young Adults.
Article in Orthopaedic journal of sports medicine, 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
Background: Although marijuana (MJ) use is likely common among adolescents and young adults undergoing hip arthroscopy (HA) for femoroacetabular impingement (FAI), there is a dearth of literature investigating the effect of MJ use on surgical outcomes. Purpose: To determine the effect of preoperative MJ use on outcomes among young patients undergoing HA for FAI. Study Design: Cohort study; Level of evidence, 2. Methods: Patients ≤25 years undergoing HA for FAI were included. Preoperative MJ use was self-reported during intake; this was used to define 2 subgroups: the +MJ subgroup and the non-MJ subgroup. Baseline and intraoperative variables were compared between the subgroups. Preoperative patient-reported outcome (PRO) scores were recorded, including modified Harris Hip Score (mHHS), International Hip Outcome Tool (iHOT-12), Patient-Reported Outcomes Measurement Information System (PROMIS) Depression, and PROMIS Anxiety scores. PROs were recorded at regular intervals over the first postoperative year and assessed to determine whether each patient achieved the relevant minimal clinically important difference (MCID) and Patient Acceptable Symptom State. PRO values were compared between subgroups at each time point. Pain levels and narcotic use before discharge were recorded. Results: Out of 61 included patients (65.6% male; median age, 18.6 years; range, 14.7-25.4 years), 16 (26.2%) self-reported preoperative MJ use. The +MJ subgroup and non-MJ subgroup both showed statistically significant improvements in mHHS, iHOT-12, and PROMIS Depression scores from baseline to final follow-up. Of patients with final follow-up, 87.7% achieved the MCID for both the mHHS and the iHOT-12. There were no statistically significant differences in demographic or baseline variables, surgical variables, or PRO scores between the +MJ and non-MJ subgroups. Conclusion: This study showed significant improvements in the year after HA for FAI in adolescents and young adults regardless of preoperative MJ use. Future work is needed to explore the potentially negative effect of heavy use or abuse of MJ.
