Evaluating drill speed effects on tunnel diameter in ACL reconstruction: Insights from an experimental animal study.

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
Purpose: To determine how drilling speeds affect tunnel enlargement during cruciate ligament reconstruction. Methods: Twelve adult female New Zealand rabbits, each weighing between 3 and 3.5 kg, were randomly assigned to two groups based on drilling speeds (400 RPM and 1500 RPM). Following sedation, the knee and tibia regions were shaved, and the knee joint was accessed using a medial parapatellar approach. The anterior cruciate ligament (ACL) was incised using a scalpel. Tibial and femoral tunnels were drilled with a 2 mm blunt-tip drill at the assigned group speeds. Room temperature saline was used for irrigation throughout the drilling procedure. An extensor tendon graft was harvested from the anterior cruris and sutured using the Krakow technique with 4-0 Vicryl. The graft was passed through the tunnel and secured to a pre-placed screw near the tunnels. Post-surgery, the operated extremity was not immobilised, and the rabbits were observed while moving freely within the cage. Twelve weeks post-operatively, the animals were humanely euthanized, and micro-computed tomography (CT) was employed to assess the diameters of the femoral and tibial tunnels at the proximal, middle and distal regions. Results: No statistically significant differences were found between radiological femoral and tibial tunnel diameter measurements of the 400 and 1500 RPM drilling groups 12 weeks after arthroscopically assisted ACL reconstruction in New Zealand rabbits. However, within the 400 RPM group, there was a measurable increase in the tunnel diameter in the proximal tibia and distal femur regions. Conclusion: The findings of our study suggest that concerns about higher drilling speeds in ACL surgery may be overstated, as higher speeds did not lead to significant radiological tunnel enlargement. Level of Evidence: N/A.
