Background: The anterior cruciate ligament (ACL) is the most commonly injured ligament in the body. Knee proprioception deficit often occurs after ACL injury. Current treatment choices for ACL tear incorporate both surgical reconstruction and conservative management. However, there was insufficient evidence to determine whether surgical or conservative management was superior for the treatment of ACL partial tear with regard to knee proprioception restoration. Objective: determine whether is there any difference between reconstructive surgery and conservative treatments with regard to knee proprioception in subjects with partial ACL tear.Study Design: comparative study. Subjects: 45 subjects (male only)of police academy students were participated in the study, 30 patients with partial ACL tear (experimental group) were selected post different treatment protocols, with ages ranging from 20 to30 years without any other associated knee injuries. In addition to 15 subjects (control group) served as normal control matched for age and sex. Methods: Subjects were divided into three groups; group (A) Include 15 patients with partial ACL post-rehabilitation after surgical reconstruction through an arthroscopic procedure, group (B) Include 15 patients with partial ACL tear post-conservative management , and group (C); control group. Knee proprioception was evaluated through Biodex Isokinetic Dynamometer by an active mode at two knee angles; 30{u00B0}, 60{u00B0}, the experimental groups underwent Proprioceptive evaluation post the end of 20weeks of rehabilitation. Results: There were no significant differences between the experimental groups with regard to knee proprioception. Conclusion: within the limitation of this study, both reconstructive surgery and conservative management of ACL partial tear were effective and nearly equivalent with regard to knee proprioception restoration in police academy students
