Pseudopatella Identified in Bilateral Gonarthrosis: A Case Report of Preoperative Recognition and Surgical Considerations in Total Knee Arthroplasty.
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
Pseudopatella is a rare ossification within the quadriceps tendon, often associated with chronic mechanical stress or degenerative knee conditions, such as gonarthrosis. We report the case of a 59-year-old patient with bilateral gonarthrosis who underwent cruciate-retaining total knee arthroplasty (TKA). Intraoperatively, a pseudopatella was identified within the quadriceps tendon. To optimize the function of the extensor mechanism and prevent future complications, the ossified mass was carefully excised. The procedure proceeded with standard implant placement, ensuring proper alignment, stability, and soft tissue balance. Postoperative recovery was uneventful, and at follow-up, the patient achieved 100 degrees of flexion and full extension. This case underscores the importance of recognizing pseudopatella as a potential intraoperative finding during TKA, particularly in patients with advanced degenerative joint disease. Appropriate management can enhance joint biomechanics, reduce the risk of complications, and contribute to favorable functional outcomes.
