    Abstract:
    Health care reform will quite possibly change the delivery of physical therapy by demanding physical therapists to be more accountable for providing appropriate, yet cost-effective treatment. The purpose of this study was to retrospectively compare the results after anterior cruciate ligament (ACL) reconstruction between two groups of patients with different numbers and frequencies of physical therapy visits postoperatively. Two random samples of 100 patients from a total of 1,345 patients identified as undergoing ACL reconstruction from 1990 through 1993 were included. Group A patients attended physical therapy regularly and participated in a home exercise program, while patients in Group B attended limited physical therapy visits and also performed a prescribed home exercise program. Both groups followed the same postoperative rehabilitation program for early range of motion, early weight bearing, and muscle control. The outcome variables measured 1, 6, and 12 months postoperatively included the number of structured visits to physical therapy, range of motion, isokinetic strength testing, and subjective rating. Group A averaged 20 visits in the first 6 months while Group B averaged seven visits. The results revealed no significant difference for flexion, isokinetic strength, or subjective rating. There was a significant difference for hyperextension (Group A, 2 degrees; Group B, 6 degrees). The results of this investigation indicated that by following a structured physical therapy program postoperatively, it is possible for patients to achieve a successful outcome with a limited number of routine physical therapy visits.
