Arthroscopic biological internal bracing with remnant repair for subacute ACL femoral avulsionsArthroscopic anterior cruciate ligament (ACL) reconstruction predictably restores sagittal plane knee stability, however its inability to replicate a complex fan-shaped ligament of multiple fascicles, along with deficient restoration of normal rotational knee kinematics, results in failure to reverse a high risk for premature post-traumatic osteoarthritis. Although arthroscopic repair for acute ACL femoral avulsions is proposed to counter these deficiencies, the risk of early failure following non-healing, along with lack of convincing evidence of efficacy has impeded its universal acceptance.
Anatomical hamstring tendons ACL reconstruction with the “linking rings” techniqueHamstring tendons (HTs) are one of the most commonly used autografts for anterior cruciate ligament (ACL) reconstruction (ACLR). However, the tendon-to-bone healing of the HTs grafts within the bone tunnels has always been a concern. Periosteum contains pluripotent stem cells with osteogenic and chondrogenic potential which can allow a direct, stronger and faster healing of the HTs graft within the bone tunnels. In this technical note, we present a modification of anatomical ACLR with the semitendinosus tendon (ST) graft and periosteum augmentation using the “linking rings” technique.
