Outcomes After Total Knee Arthroplasty in Patients With a History of Patella Fracture: A Propensity Score-Matched Analysis.

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
backgroundPosttraumatic osteoarthritis is a common indication for total knee arthroplasty (TKA). The purpose of this study was to evaluate the association between a history of patella fracture and postoperative complication rates after TKA.
methodsPatients diagnosed with a patella fracture before undergoing TKA were identified from a large national database and matched to a control cohort using propensity scoring. Rates of medical complications occurring within 90 days of TKA and surgery-related complications occurring within 1 year of TKA were compared using odds ratios. Healthcare utilization outcomes including 90-day emergency department (ED) presentation, hospital readmission, and total cost were also compared.
resultsCompared with a propensity-matched control cohort, TKA patients with a history of patella fracture had a lower incidence of pulmonary embolism (OR 0.74, P = 0.0442) and higher incidences of periprosthetic joint infection (OR 1.68, P < 0.0001), revision surgery (OR 1.84, P < 0.0001), dislocation (OR 1.61, P = 0.026), lysis of adhesions (OR 2.21, P = 0.0082), and wound disruption (OR 1.52, P < 0.0001). A history of patella fracture was also associated with an increased rate of ED presentation (OR 1.08, P = 0.0454) and increased total cost ($14,359 vs. $12,786, P = 0.0003).
conclusionA history of patella fracture is associated with early surgery-related complications after TKA including periprosthetic joint infection, revision surgery, dislocation, lysis of adhesions, and wound disruption. Healthcare utilization is increased among these patients with higher rates of ED presentation and increased total cost. These findings allow for more accurate risk stratification and counseling of patients. LEVEL OF EVIDENCE: III, Retrospective review.
