Clinical and radiological outcome of acute quadriceps tendon repair at 2 - year follow-up.
Article in Archives of orthopaedic and trauma surgery, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
purposeThough previous studies on surgical quadriceps tendon repair reported good to satisfactory results its impact on knee extensor strength and patellofemoral joint is unknown. The purpose of the study was to assess the clinical and functional outcome by quantifying subjective knee related outcome, isokinetic extensor strength complemented by magnetic resonance imaging (MRI).
methodsFor this retrospective clinical trial twenty-one patients with a mean age of 59.1 (±14.9) years were carried out for follow-up evaluation. For clinical outcome numeric rating scale for pain (NRS), Kujala anterior knee pain score, Knee osteoarthritis outcome score (KOOS) with its subscores, Tegener Activity Score (TAS), Isokinetic extensor strength testing (ISO) and the Limb symmetry index (LSI) were utilized. Muscle volume (V
resultsMean follow-up was 56.2 (± 17.5) months. Clinical outcomes in mean were as follows: NRS 1.7 (±2.0), Kujala score 75.8 (± 15.8) points; KOOS 62.9 (±30.6) % (Subscores: (KOOS
conclusionDistal quadriceps tendon repair leads to satisfactory subjective outcome in patients with low to moderate activity levels. Tendon integrity was reliably restored. However, extensor strength deficits remain in more than 40% of patients. Atrophy signs of advanced fatty infiltration were recorded in 15% and patellofemoral cartilage defects in 20% of all patients, indicating that previous assessment tools do not display functional outcome adequately.
