Key Factors Influencing Surgical Outcomes in Quadriceps Tendon Rupture: A 16-Year Case Series From a High-Volume Tertiary Trauma Centre.

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 Quadriceps tendon rupture (QTR) causes significant functional impairment, with recent studies showing an increasing incidence of these injuries. A delay in diagnosis significantly impacts outcomes, necessitating prompt diagnosis and treatment. This case series, spanning 16 years at a tertiary centre, examines factors influencing surgical outcomes, focusing on evaluating the correlation between diagnostic methods, time to surgery (TTS), surgical techniques and post-operative outcomes. Methods We conducted an observational retrospective cohort study with data collected from a trauma registry and physiotherapy records. Study variables were identified through a literature search and expert consultation. Data were gathered based on pre-, intra- and post-operative factors that could impact patient outcomes. Pearson correlation and analysis of variance (ANOVA) were used for statistical analysis; statistical significance was defined as p < 0.05. Results Forty-six patients (predominantly men, aged 50-70 years) were included, with falls on a flexed knee the most likely aetiology. Choice of imaging significantly influenced TTS (p = 0.0148). A combination of X-ray and ultrasound scan (USS) proved most sensitive for diagnosis, although X-ray-only diagnosis resulted in shorter surgery wait times. TTS averaged 11 days, with over 52% waiting >72 hours. More than 90% of tears were osteotendinous, with transosseous tunnels (TT) (63%) being the predominant approach. No significant difference was seen in post-operative range of motion (ROM) or recovery time between surgical techniques. Conclusion This series evaluates the impact of imaging modalities, surgical methods and TTS on functional outcomes post-QTR repair. Our results reinforce the male predominance and age-related risk of QTR. Comparable outcomes were observed across different surgical techniques, and surprisingly, early and delayed surgeries showed no differing effect on post-operative outcomes. We highlight the delay to surgery when USS is involved in the diagnostic workup. Future research should investigate whether optimising clinical assessment and X-ray interpretation can negate the need for USS in diagnosis, thereby reducing wait times.
