Ipsilateral Patellar Tendon Reconstruction Using Quadriceps Tendon-Patella Bone Autograft for Simultaneous Rupture of the Patellar Tendon, Anterior Cruciate Ligament, and Medial Collateral Ligament: A Case Report.

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
Simultaneous rupture of the patellar tendon (PT), anterior cruciate ligament (ACL), and medial collateral ligament is a relatively rare type of trauma. We present a two-stage treatment for this type of trauma. A 47-year-old male who fell from a height of 2 m. The ruptured part of the PT was in poor condition and required strong fixation; therefore, we reconstructed the tendon using quadriceps tendon-patellar bone (QTB) autograft as the first stage of the procedure. After nine months, ACL reconstruction using the semitendinosus tendon (ST) was performed as the second stage. Eighteen months after the first operation, the range of motion (ROM) was 0° of knee extension without any extension lag and 135° of flexion. Radiographs revealed that bone graft incorporation was achieved with an Insall-Salvati ratio of 1.11. The Lachman test and pivot-shift test were negative. There were no postoperative complications, including retear, loss of ROM, or infection. The use of QTB autografts for the rupture of the PT has several advantages. First, the enthesis can be reconstructed with healthy tissue, and the PT length can be maintained. Second, autografts can be expected to be incorporated. Third, the ST can be preserved for ACL reconstruction without invading the contralateral leg.
