NCT00423982

Brief Summary

The number of patients requiring joint replacement is increasing due to its success in restoring function and pain relief, and the growing population of the elderly. One of the most serious complications of arthroplasty is joint prosthesis infection. Due to the absence of prospective, randomized, controlled studies, there is no consensus concerning diagnosis and treatment of prosthetic joint infections. The main objective of this trial is to evaluate the clinical efficacy of rifampin combination therapy versus monotherapy using cloxacillin or vancomycin in early staphylococcal infections after total hip and knee arthroplasty.

    2 years

Study Arms (2)

Rifampicin-combination therapy

ACTIVE COMPARATOR

Cloxacillin or vancomycin in combination with Rifampicin. Treatment of early staphylococcal prosthetic joint infections in addition to debridement and retention of the prosthesis.

Drug: Rifampin-combination therapy

Monotherapy

ACTIVE COMPARATOR

Cloxacillin or vancomycin in the treatment of early staphylococcal prosthetic joint infections in addition to debridement and retention of the prosthesis.

Drug: Monotherapy

Interventions

Rifampin 300 mg x 3 po and cloxacillin 2 g x 4 iv for two weeks. Then rifampin 300 mg x 3 po and cloxacillin 1 g x 4 po for 4 weeks. In case of methicillin resistance, rifampin 300 mg x 3 po and vancomycin 1 g x 2 iv for 6 weeks.
