Purpose It was aimed to reveal the relationship between CRP level after knee arthroplasty and gender difference and arthroplasty type. Methods Preoperative and postoperative (1st and 7th day, 1st and 3rd months) CRP values of the patients who underwent TKA or UKA were examined. The data were compared by categorizing them into primary male-female, secondary TKA-UKA groups. Results 967 patients were included in the study (151 male, 685 female in the TKA group and 25 male, 106 female in the UKA group) In the TKA group, the mean age was 67.38 in males and 65.54 in females. In the UKA group, the mean age was 58.72 in males and 57,63 in females. CRP values were found to be statistically significantly lower in females compared to males in the preoperative period, postoperative 1st and 3rd months in patients who underwent TKA (p < .05). In the UKA group, it was found to be significantly lower in females in the preoperative period and at the postoperative 3rd month, p < .05). When the CRP values and their effect on the course of arthroplasty were evaluated according to the type of arthroplasty, there was no significant difference between the CRP values of the preoperative patients (p = .686). In addition, in the comparison made on the postoperative 1st day, 1st week, 1st month, and 3rd month, CRP values of the patient who underwent UKA were found to be significantly lower (p < .05). When analyzed separately by arthroplasty type, postoperative CRP values decreased to normal limits in 96.3% of patients who underwent TKA and 98.5% of patients who underwent UKA in the third month. Conclusions Our study showed that the uncomplicated course of CRP after TKA and UKA is gender-specific, and higher CRP values are observed in males than in females. The UKA group exhibited significantly lower postoperative CRP levels than the TKA group.
