Patellar Tendon Rupture Following Total Knee Arthroplasty: A Case Report.
Article in Cureus, 2025. 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
Patellar tendon rupture following total knee arthroplasty (TKA) is a rare but serious complication that has the ability to result in significant functional impairment due to extensor mechanism disruption. In the early postoperative period, diagnosis may be challenging, especially if initial radiographs are unremarkable and some function is preserved. We present the case of a 60-year-old female who presented to the emergency department with right-sided knee pain following a mechanical fall approximately one month after undergoing right TKA. Initial evaluation showed intact prosthetic components, the ability to bear weight with assistance, and preserved passive range of motion, leading to discharge. Persistent pain prompted further outpatient evaluation. Magnetic resonance imaging subsequently demonstrated a complete rupture of the patellar tendon. The patient underwent surgical reconstruction with an Achilles tendon allograft and tolerated the procedure without any complications. This case highlights the potential for delayed diagnosis of patellar tendon rupture in a patient who recently underwent TKA. It also supports Achilles tendon allograft reconstruction as a viable and reliable option when primary repair is not feasible.
