This study examined the relationship between adherence to postoperative physical therapy and outcome after surgical reconstruction of the anterior cruciate ligament (ACL) of the knee in a sample of 72 men and 36 women. Indices of adherence were obtained during the first 6 weeks of postsurgical rehabilitation. Outcome measures were administered before surgery and approximately 6 months after surgery. Results of a canonical correlation analysis indicated a statistically significant association between the adherence variables and the outcome variables (r = 0.56, p < 0.05). Greater attendance at rehabilitation sessions and more favourable practitioner ratings of adherence during rehabilitation sessions were associated with fewer self-reported knee symptoms and greater knee laxity. The findings highlight the complex nature of the adherence – outcome relationship.
