Abstract
Five hundred fifty-three patients undergoing hip and knee reconstructive procedures in one institution that used a patient management system were compared with a retrospective group of 340 patients undergoing similar procedures in the same institution. All procedures were performed by one surgeon and the same patient management team. Measures of length of stay, discharge disposition, and hospital charges were recorded for all patients in each subgroup of total hip arthroplasty, revision total hip arthroplasty, total knee arthroplasty, revision total knee arthroplasty, unicompartmental knee arthroplasty, and bilateral procedures. The length of stay and hospital charges were reduced significantly in all groups, whereas the percentage of patients discharged to home was unchanged. There was no significant difference in complication rates between the two groups.
