Secondary patellar resurfacing after total knee arthroplasty: Functional but not clinical score improvements in a retrospective multicenter 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: The role of secondary patellar resurfacing (SPR) in managing persistent anterior knee pain following total knee arthroplasty (TKA) without prior patellar resurfacing remains controversial. While primary patellar resurfacing is routine in some regions, others adopt a selective approach, leading to variability in patient outcomes and management strategies. Methods: This retrospective multicenter study analysed patients who underwent SPR after primary TKA between 2012 and 2022. Inclusion criteria encompassed patients with refractory anterior knee pain after an unresurfaced primary TKA, with at least 6 months of follow-up. Pre- and postoperative knee society scores (KSS), range of motion, radiographic parameters and patient satisfaction were assessed. Thirty-four patients (mean age: 69.8 ± 9.3 years, 68% women) met the inclusion criteria. Preoperatively, 94% of patients reported dissatisfaction. Results: Following SPR ( Conclusion: SPR may provide meaningful clinical improvements in select patients with persistent anterior knee pain following TKA. A thorough diagnostic workup, including imaging and clinical assessment, is crucial for identifying suitable candidates. Future studies should focus on refining patient selection criteria and standardising indications for SPR. Level of Evidence: Level IV.
