Background and Objectives: A lesion of the anterior cruciate ligament (ACL) is a major trauma of the knee. Functional tests are often used to assess knee function after knee ligament injuries. The purpose of this study was to compare some functional tests and disability level between patients with ACL deficiency (ACLD), ACL Reconstruction (ACLR), and healthy people (HP).
Subjects and Methods: Thirty six men with diagnosed ACLD, ACLR, HP (n=12 in each group) participated in this study. After completing Knee Injury and Osteoarthritis Outcome Score (KOOS) questionnaire, participants performed five functional tests, including single leg hop, cross hop, vertical jump, shuttle run, co-contraction with intact and injured leg.
Results: Findings showed significant differences in distance of single leg hop and cross hop tests between either ACLD or ACLR patients and healthy people (P<0/05,P<0/05, respectivly). While comparing two legs, the distance of single leg hop, cross hop and vertical jump tests in both ACLD and ACLR patients were significantly different (P<0/05). In addition three dimensions of KOOS questionnaire including pain, activity of daily living and sport and recreational activities showed significant differences between ACLD and ACLR patients (P<0/05).
Conclusion: These functional tests are appropriate for assessment of function and disability levels in patients with ACLD and ACLR.
