Background: Recovery from anterior cruciate ligament reconstruction (ACLR) requires an intensive course of postoperative rehabilitation. Although guidelines outlining evidence-based rehabilitation recommendations have been published, actual practice patterns of physical therapists are unknown.
Objectives: To analyze the current landscape of clinical practice as it pertains to rehabilitation progression and the use of time and objective criteria in rehabilitation following ACLR.
Methods: In this cross-sectional study, an online survey was distributed to members of the Academy of Orthopaedic Physical Therapy, the American Academy of Sports Physical Therapy, and the Private Practice Section of the American Physical Therapy Association between January and March 2017.
Results: The study analyzed a sample of 1074 responses. Supervised physical therapy was reported to last 5 months or less by 56% of survey respondents. The most frequent time frames for activity progression were 3 to 4 months (58%) for jogging, 4 to 5 months (50%) for modified sports activity, and 9 to 12 months (40%) for unrestricted sports participation. More than 80% of respondents reported using strength and functional measures during rehabilitation. Of those physical therapists who assessed strength, 56% used manual muscle testing as their only means of strength testing. Single-limb hop testing (89%) was the most frequently reported measure used to allow patients to begin modified sports activity following ACLR. Performance criteria for strength and functional tests varied significantly across all phases of rehabilitation. The 45% of respondents who reported using patient-reported outcome measures indicated that just under 10% of those measures involved fear or athletic confidence scales.
Conclusion: Considerable variation in practice exists among American Physical Therapy Association members regarding rehabilitation following ACLR. This variability in practice may contribute to suboptimal outcomes and confusion among practitioners and patients. J Orthop Sports Phys Ther 2018;48(10):801-811.
