Use of temporary implants (spacers) in revision knee arthroplasty

Igor Zazirniy


There is currently no consensus concerning the best option of a spacer for two-stage arthroplasty with an infected knee prosthesis. This retrospective study examined case histories of 16 patients who underwent two-stage revision surgery with use of re-sterilized prosthesis elements as spacers. The results of operations, which were performed within the same period (2004–2010) with use of cement spacers (8 patients), were retrospectively analysed. During the postoperative observation period, which averaged 21 months, 24 cases (100 %) developed control over infection, good or excellent clinical results being observed in 18 cases. Two patients did not undergo reimplantation. The patients, treated with re-sterilized elements, had a greater range of movements during the period between the two operations. Reimplantations with use of prosthetic spacers lasted less time, blood losses were lower. We believe that re-sterilized prosthesis elements are a reliable and efficient alternative to cement spacer for treating infected prosthetic knee joint.
