Knee Crepitus and Osteoarthritis Features in Young Adults Following Traumatic Knee Injury.
Article in Arthritis care & research, 2026. 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
objectiveThis study explored the association between knee crepitus and the presence, and worsening, of structural osteoarthritis features and self-reported outcomes in young adults following traumatic knee injury.
methodsOne year following anterior cruciate ligament reconstruction (ACLR), 112 participants (41 female participants; median age 28 years old) self-reported the presence and/or absence of knee crepitus using an item from the Knee Injury and Osteoarthritis Outcome Score (KOOS). Patellofemoral and tibiofemoral osteoarthritis features (ie, cartilage lesions, osteophytes, and bone marrow lesions) were assessed from magnetic resonance imaging scans at one and five years after ACLR. Self-reported outcomes were assessed with two KOOS subscales (pain and quality of life [QoL]) and the International Knee Documentation Committee subjective evaluation form (ie, self-reported function). Poisson regression evaluated the relationship between self-reported crepitus and the presence/worsening of structural osteoarthritis features. General linear models explored the relationship between crepitus and self-reported outcomes.
resultsSelf-reported crepitus was associated with full-thickness patellofemoral cartilage lesions one year after ACLR (prevalence ratio 2.70, 95% confidence interval [CI] 1.41-6.39) but not the risk of worsening structural osteoarthritis features between one and five years after ACLR. Those with crepitus reported worse pain (β = -6.42, 95% CI -10.47 to -2.36), QoL (β = -10.39, 95% CI -18.58 to -2.20), and function (β = -5.49, 95% CI -10.92 to -0.06) one year after ACLR but greater improvement in pain and function between one and five years.
conclusionSelf-reported knee crepitus was associated with the presence of full-thickness patellofemoral cartilage defects one year after ACLR but was not associated with a greater risk of worsening structural osteoarthritis features up to five years after ACLR. One year after ACLR, those with crepitus reported worse pain, knee-related QoL, and function.
