Patellar Tendon Reconstruction With Achilles Allograft: A Technical Note.
Article in Video journal of sports medicine. 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
Background: Patellar tendon ruptures are relatively common injuries, often caused by high tensile forces on a weakened tendon. In younger patients, they typically result from eccentric loading on the extensor mechanism, whereas in older patients, trauma is the more common cause. These injuries can be functionally limiting and challenging to treat when chronic due to tendon atrophy, scarring, and proximal retraction. Indications: Reconstruction is indicated for patients with chronic, symptomatic patellar tendon ruptures confirmed by clinical and radiographic evaluation. Technique Description: A longitudinal midline incision was made, and dissection proceeded through the subcutaneous tissue to identify the ruptured tendon. Fibrotic tissue was debrided, and the tendon length was adjusted to restore patellar height. Three 3.5-mm drill holes were created at the inferior pole of the patella for 5.5-mm bio-composite anchors. Sutures were placed in a Krackow interlocking fashion, with limbs tied in full extension. An Achilles tendon allograft with a bone block was prepared. A 10 × 20 mm tunnel was drilled distal to the tibial tubercle, and the graft was secured with a metal interference screw. The graft was looped proximally and secured to the native tendon with suture tape in a double-layer Krakow configuration. Additional anchors were placed at the tibial tubercle to secure the distal graft. Results: This technique demonstrated excellent functional outcomes, with radiographic evidence of a healed, well-fixed graft and restored patellar height. The patient achieved 120° of knee flexion, full extension, and independent ambulation at the 6-month follow-up. Discussion/Conclusion: Achilles allograft augmentation offers a reliable solution for chronic patellar tendon ruptures, especially in cases with tendon atrophy or retraction, eliminating donor site morbidity and enabling strong fixation and early rehabilitation.
