Prognostic opportunities for infectious inflammatory complications in primary endoprosthesis of large joints

The aim: to study prognostic and diagnostic opportunities for infectious inflammatory complications of primary endoprosthesis of hip and knee joints on the basis of cellular immunity indices. Material and Methods. 174 patients with large joint osteoarthrosis aged 61 ±13 yrs which had undergone total joint replacement were enrolled into the study. The experimental group consisted of 22 patients with infectious inflammatory complications emerging from 6 up to 12 months postsurgically. The comparison group included 152 patients with favorable postsurgical period. We carried out WBC differentiation by subpopulations (lymphocytes, monocytes, granulocytes) and their immunophenotyping. 40 conventionally healthy individuals comprised the control group. The outcomes were estimated using the worked-out score system. Results. In patients with favorable postsurgical period total value of indices equaled not more than 4-6 points. In all the other cases the risk of infectious inflammatory complications is significantly higher and reaches its maximal values in patients with 10-12 points. Conclusion. The assessment of laboratory indices reflecting immune response of the body allows estimating the risk of infectious inflammatory postsurgical complications and diagnosing them in III grade large joint osteoarthorisis patients after total replacement.
