Abstract

Objectives Periprosthetic infection (PI) after total hip and knee replacement (THR, TKR) is an actual and not fully solve problem of joint surgery in RP. We intend to compare a) the frequency of PI after THR versusTKR and b) results of the treatment for this complication

Methods 1201 THR, n-1069 PTC, F/M – 3,6:1, age -49,6 (16-83), rheumatoid arthritis (RA) -323 PTC, juvenile rheumatoid arthritis (JRA) -124, ankylosing spondylitis (AS) -80, systemic lupus erithematosis (SLE) -79, psoriatic arthritis (PsA) -18, systemic scleroderma (SSD) -11, osteoarthritis (OA) -353, others (O) -81. 234 TKR, n-197 PTC, F/M – 4,9:1, age - 47,7 (19-75), RA -139 PTC, OA -38, JRA -14, one with JRA, SLE and AS PI registered in 7 THR with RA (2,18%), 1 with JRA (0,8%) and 1 with OA (0,28%), in 6 TKR with RA (2,5%). The treatment of PI included revision surgery, influx-drain system with daily constant antibiotics irrigation during two weeks.

Results THR implants: one had preserved, 8-removed and 7 PTC of them are needing in repeated revision surgery. Implants of TKR: 2 had preserved, 3 – removed with subsequent arthrodeses. One THR patient died from diabetes complications, one TKR –died from infarction

Conclusions Risk periprosthetic infection in TKR-patients a 1,5 times higher than THR-patients. RA-patients with THR had a 10 times higher risk periprosthetic infection than OA patients and it can assume, that rheumatoid arthritis may be one from some risk factors for this complication.
