Impact of tunnel enlargement on patient-reported outcomes following isolated posterior cruciate ligament reconstruction.
Article in Journal of orthopaedic surgery and research, 2025. 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
backgroundTunnel enlargement (TE) might jeopardize knee function and ligament stability after revision surgery of anterior cruciate ligament reconstruction. To date, only few studies concern TE following posterior cruciate ligament reconstruction (PCLR). This study aims to determine TE after isolated PCLR and its relationship with patient-reported outcomes.
methodsPatients who received primary isolated PCLR were screened. Femoral and tibial tunnel size was measured using an anteroposterior and lateral view of radiographs at least 6 months after surgery. TE is considered significant if the width of the bone tunnel increases by 25% over the drilled size. Patient-reported outcomes were determined using the subjective International Knee Documentation Committee (IKDC) score and the Lysholm score. The association between patient baseline characteristics, patient-reported scores, and the severity of TE was investigated.
resultsFifty-four patients were enrolled. TE was observed in 15 femoral tunnels and in 14 tibial tunnels. The average TE rate is 17.9% for femur and 7.9% for tibia. No correlation between the level of TE and patient-reported outcomes is noted. However, when patients are classified into TE and non-TE group on the basis of 25% of enlargement, those who exhibit femoral TE have a lower postoperative Lysholm score (81.1 ± 13.0 vs. 90.5 ± 12.3, P = 0.031) and those with tibial TE have a lower postoperative IKDC score (76.0 ± 17.4 vs. 87.1 ± 12.1, P = 0.031).
conclusionsThe overall incidence of femoral and tibial TE after isolated PCLR is low. However, femoral and tibial TE are correlated with worse patient-reported outcomes in terms of the lower postoperative Lysholm and IKDC scores.
