Objective To evaluate the effectiveness of non-operative treatment for the acute intra-sy-novial sheath anterior cruciate ligament(ACL) rupture. Methods Twenty-eight patients diagnosed asthe acute intra-synovial sheath ACL rupture at outpatient clinic between May 2014 and July 2016 were included. All patients were immobilized with knee braces for 6 weeks,followed by range of mo-tion(ROM) training and partial to full weight-bearing of knees. All patients returned 3 months laterfor MRI scanning and those with the side-to-side difference of the anterior-posterior laxity less than 5 mm continued with non-operative treatment,followed up for MRI examination and clinical assessments6 and 12 months later. Results Four patients dropped out because they didn't meet the stability crite-ria at 3 months after the treatment,3 of whom received surgical reconstruction and 1 with musclestrengthening training. Another patient received surgical reconstruction at 5 months due to re-injury.The remaining 23 patients achieved satisfactory results at 12 months after the treatment,with the aver-age side-to-side difference of the anterior-posterior laxity of 2.1 mm(0-4 mm),MRI good-to-excellentrate of 85.2%(8 of Grade 1 and 15 of Grade 2),subjective IKDC(International Knee DocumentationCommittee) score of 92.71(89.7-98.9),Lysholm score of 91.6(86-95),and modified Larson score96.4(92-99). Conclusions Patients with the acute intra-synovial sheath anterior cruciate ligament(ACL) rupture showed satisfactory functional scores and objective stability and healing on MRI afterthe non-operative treatment.
