Objective: To document outcomes of patients undergoing a two stage total hip revision with the PROSTALAC system.

Design: Retrospective chart review, concurrent prospective cohort.

Setting: Three tertiary health care centers

Subjects: Patients undergoing two stage exchange arthroplasty in whom the PROSTALAC hip system was utilized.

Outcome Measures:

Functional outcome scores

Identification of organisms

Retention of prosthesis (up to two years)

Results:

Demographics:

v 25 patients: 9 completed 2^nd stage

v 15 - PROSTALAC in situ.

Identification of Organism:

v 17 positive identifications at 1^st stage

v 2 positive identifications at 2^nd stage

Functional Outcome Scores:

v HHS: One excellent score, 3 fair and 2 poor.

v WOMAC: 63% have minimal pain and 50% have good function.

Discussion:

v Two patients did not clear their infection at 2^nd stage but have responded well to IV antibiotics.

v Retention of prosthesis is 100%.

v To our knowledge there are no published functional scores on patients in the interval period.

v Patients do not do as well as compared to primary THR, as expected, but have minimal pain and reasonable function.
