Patellar tendon repair restores extensor mechanism function with a low complication rate: A systematic review.
Review in Journal of orthopaedics, 2025. 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
Introduction: The patellar tendon plays a crucial role in knee extension and lower extremity mobility. Although PT ruptures are rare, they result in severe loss of function when untreated. The purpose of this study was to evaluate clinical and functional outcomes and complications following primary, acute patellar tendon (PT) repair. Methods: In accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, PubMed, Embase, and Cochrane Library databases were searched in August 2024 for studies published after 2004. Studies were included if they met these criteria: evaluated patients who underwent acute PT repair with any technique including for mid-substance tear or avulsion, were prospective or retrospective studies, and reported functional outcomes or complications. Studies not written in English were excluded. Results: The initial screen identified 1737 studies, 9 of which were included in this systematic review. There were three retrospective cohort studies, three retrospective case series, one retrospective case control study, and two prospective case series. Each study had low risk of bias. A total of 970 patients (93.8 % males) were included. Mean age across studies ranged from 32.1 to 44.6 years. Five included studies reported on mean extension at follow-up, ranging from 0 to 6.4 degrees of extension. Five included studies reported on mean flexion at follow-up, ranging from 128.5 to 143.3 degrees of flexion. The range of re-rupture and re-operation were 0-21.4 % with an overall re-rupture rate of 3.9 % and an overall re-operation rate of 5.7 %. Only one study reported a significant difference in re-rupture rates with transosseous repair versus suture anchor repair (7.5 % versus 0 % respectively). Other complications identified were venous thromboembolism (VTE) (0-5.0 %), stiffness (0-35.0 %), hardware discomfort (0-5.0 %), and infection (0-5.0 %). Conclusions: Patellar tendon repair with both transosseous and suture anchor technique restores range of motion in patients post-operatively with a low complication rate. Decisions regarding operative technique should be tailored to individual patient characteristics and surgeon preferences. Level of evidence: Level IV, systematic review of level III-IV studies.
