Anterior cruciate ligament (ACL) reconstruction (ACLR) is the established treatment for ACL injuries, with graft selection significantly influencing recovery. 1 This study compared knee flexor and extensor strength recovery in 50 ACLR patients who received either a synthetic JewelACL neoligament or a semitendinosus (ST) autograft. Isokinetic testing using the BIODEX SYSTEM 4 PRO was performed at various velocities, with peak torque and Limb Symmetry Index (LSI) assessed post-rehabilitation. Preliminary findings indicate that the JewelACL group demonstrated superior muscle strength recovery across multiple parameters. These results suggest that the JewelACL neoligament may promote enhanced muscle strength recovery after ACLR. Further research is warranted to validate these findings and evaluate long-term outcomes.

摘要

Anterior cruciate ligament (ACL) reconstruction (ACLR) is the established treatment for ACL injuries, with graft selection significantly influencing recovery. 1 This study compared knee flexor and extensor strength recovery in 50 ACLR patients who received either a synthetic JewelACL neoligament or a semitendinosus (ST) autograft. Isokinetic testing using the BIODEX SYSTEM 4 PRO was performed at various velocities, with peak torque and Limb Symmetry Index (LSI) assessed post-rehabilitation. Preliminary findings indicate that the JewelACL group demonstrated superior muscle strength recovery across multiple parameters. These results suggest that the JewelACL neoligament may promote enhanced muscle strength recovery after ACLR. Further research is warranted to validate these findings and evaluate long-term outcomes.
