Routine Histopathological Analysis of the Synovium in Patients with Primary Total Knee Arthroplasty

J Knee Surg DOI: 10.1055/s-0040-1709181Although there are numerous studies about routine histopathological analysis during arthroplasty surgeries, most of them showed that new diagnoses have rarely been obtained as a result. The aim of this study was to evaluate the efficacy of routine pathological analyses of synovia resected during primary total knee arthroplasty in patients with osteoarthritis and its relevance in the treatment process. Of the 47 included patients who were followed up prospectively, 26 patients had clinical and histopathological concordant diagnoses and 21 patients had discrepant diagnoses. Oxford knee score and visual analogue score were performed for all the patients. Kallgren-Lawrence score was used for radiological analyses. The Mann-Whitney U test was used to examine the differences between the abnormally distributed variables. Mean age was 65.9 ± 4.3 years (range, 50–89 years) and mean follow-up time was 19 ± 7.8 months (range, 6–39 months). Grade IV gonarthrosis was found to be statistically lower in the discrepant group (p = 0.046). The mean preoperative Oxford knee score was 16.8 ± 2.3 (range, 2–23) and the mean postoperative Oxford knee score was 44.6 ± 1.8 (range, 27–48; p = 0.016). Postoperative Oxford knee scores and VAS were significantly increased in both the concordant and discrepant groups (p = 0.026 and p = 0.035, p = 0.019 and p = 0.039, respectively). Resection and histopathologic anal...
