C-reactive protein levels after 4 types of arthroplasty.

Shen H, Zhang N, Zhang X, Ji W - Acta Orthop (2009)

Bottom Line: The peak CPR levels after hip resurfacing were lower than those after conventional primary THA.The peak CRP levels after computer navigation-assisted TKA were lower than those after conventional primary TKA.The extent of bone and bone marrow injury rather than the region of surgery or the amount of soft tissue damage appears to determine the extent of the postoperative CRP response.

ABSTRACT

Background and purpose: Postoperative C-reactive protein (CRP) levels in serum appear to reflect surgical trauma. We examined CRP levels after 4 types of arthroplasty.

Material and methods: We investigated 102 patients who had total knee arthroplasty (TKA), computer navigation-assisted total knee arthroplasty (NAV-TKA), hip resurfacing arthroplasty (metal on metal, MMSA) and total hip arthroplasty (THA), respectively. CRP levels were estimated before surgery and postoperatively at 2 and 7 days.

Results: Postoperatively, the peak CRP levels were highest on the second day after surgery in each of the groups. The peak CPR levels after hip resurfacing were lower than those after conventional primary THA. The peak CRP levels after computer navigation-assisted TKA were lower than those after conventional primary TKA.

Interpretation: The extent of bone and bone marrow injury rather than the region of surgery or the amount of soft tissue damage appears to determine the extent of the postoperative CRP response.

Figure 0003: CRP response after 4 different types of arthroplasty.

Mentions: Before operation, CRP levels were similar in the 4 groups. After surgery, the CRP levels increased in all patients. For each type of operation, the CRP profile after surgery had a characteristic pattern although the maximum amplitude varied between patients. For each group, the peak level of CRP was reached on the second day after surgery, after which it decreased (Figure 3).
