Editorial Commentary: Three-Dimensional Printing and Stem Cells May Be a Game Changer for Recovery After Anterior Cruciate Ligament Reconstruction.
Placing stem cells at the tendon-bone interface of a soft tissue anterior cruciate ligament (ACL) reconstruction in an animal model accelerates graft incorporation at 12 weeks. A 3D-printed scaffold used to deliver the stem cells completely degraded at 12 weeks. Future clinical application of similar technology may improve outcomes after ACL reconstruction.

To investigate knee kinematics in response to physical examinations to determine the effect of anterolateral capsular injury and lateral extra-articular tenodesis (LET) in anterior cruciate ligament (ACL)-deficient and -reconstructed knees. ⋯ ACL reconstruction in combination with a LET was able to reduce anterior tibial translation and internal tibial rotation in response to different physical examinations. However, combined ACL reconstruction and LET led to overconstraint of internal tibial rotation when the anterolateral capsule was intact. CLINICAL RELEVANCE: On the basis of our results, LET with ACL reconstruction restores stability in a combined ACL-injured and anterolateral capsule-injured knee. However, LET with ACL reconstruction overconstrains the knee in an isolated ACL injury.

To compare failure rates and clinical outcomes of osteochondral allograft transplantation (OCA) in anterior cruciate ligament (ACL)-intact versus ACL-reconstructed knees at midterm follow-up. ⋯ Level III, retrospective comparative study.
