Many patients experience a decline in knee function and 4-12% suffer a new ACL rupture within 5 years. According to data from the Danish ACL register, three methods of reconstruction are most prevalent, but with large variation between hospitals. This indicates lack of consensus on optimal surgical procedure.\n\nDesign:\n\nAssessor-blinded randomized controlled study. 150 patients aged 18-40 with ruptured ACL are allocated to reconstruction with tendon(s) harvested from either the semitendinosus and gracilis, or the patella tendon, or the quadriceps tendon. Patient follow-up will be conducted preoperatively and 1, 6, 12, 24 months postoperatively.\n\nPrimary technologies and outcomes:\n\n* Patient-reported knee-joint function, quality of life and donor-site morbidity is obtained with standardized questionnaires. Primary outcome is subjective knee function with the International Knee Documentation Committee evaluation form (IKDC)\n* Instrumented analysis of knee-joint coordination and neuromuscular control including 3-D motion capture and electromyography (EMG) during single leg jumps, landings and change-of-direction. Measurement of maximal explosive muscle power in knee extension and flexion. Primary outcome is relative difference between injured and healthy leg in rate of force development (RFD-LSI).\n* Standard clinical knee examination of range of motion and instrumented examination of knee-joint stability.\n* Magnetic Resonance Imaging (MRI) of the thigh muscles for examination of muscle morphology.\n\nThe trial is designed for publication in three primary publications\n\n1. \\- Patient reported effect of graft choice in ACL reconstruction\n2. \\- Biomechanical effect of graft choice in ACL reconstruction\n3. \\- Clinical effect of graft choice in ACL reconstruction\n\nAdditional secondary publications are in the pipeline. Reference to primary protocol and results will always be emphasized in secondary publication to ensure methodological transparency.",[107],"ACL - Anterior Cruciate Ligament Rupture",[109,110,111,112,113,114,36,115],"ACL reconstruction","Graft choice","Quadriceps graft","Semitendinosus\u002Fgracilis graft","Muscle morphology","Neuromuscular control","Patient reported function","2025-08-24",{"date":118,"type":119},"2025-08-28","ACTUAL",{"date":121,"type":119},"2022-05-09",{"date":123,"type":101},"2028-05-31",{"name":5,"class":6},1]
