Higher incidence of postoperative complications in patients with simultaneous patellar tendon and anterior cruciate ligament ruptures following single surgery: a case series and literature review.
Review in BMC musculoskeletal disorders, 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
backgroundPatients with simultaneous ruptures of the patellar tendon (PT) and anterior cruciate ligament (ACL) underwent PT repair and ACL reconstruction in a single or staged surgery. However, due to the limited cases, the design of previous studies was mostly case report with varying conclusions regarding recommended surgical strategy selection, the optimal surgical strategy remains a subject of debate.
methodsWe conducted a retrospective case series and literature review, including 10 cases from local institution and 27 cases from 17 studies. Demographic information, injury causes, surgical strategies, combined injuries, whether to return to (pre-injury level) sports, postoperative complications, Lysholm score and International Knee Documentation Committee (IKDC) score were identified retrospectively or reviewed from previous studies. The Fisher's exact test was used to compare the incidence of postoperative complications between different surgical strategy groups, and linear logistic regression was used to analyze factors influencing postoperative knee function scores.
resultsOf the 37 patients, 15 patients (40.5%) underwent single surgery and 22 patients (59.5%) underwent staged surgery. Postoperative complications occurred in 5 (33.3%) patients after single surgery and in none after staged surgery, with the former being significantly more frequent than the latter (P = 0.007). Linear regression of postoperative knee function scores showed that surgical strategy did not significantly affect postoperative Lysholm and IKDC scores (P = 0.327 and P = 0.348, respectively).
conclusionsThis study demonstrates that staged surgery significantly reduces postoperative complications compared to single surgery in patients with simultaneous PT and ACL ruptures and should be considered the preferred approach, especially when an expedited return to sports is not a priority.
