Arthroscopy : the journal of arthroscopic & related surgery : official publication of the Arthroscopy Association of North America and the International Arthroscopy Association
-
To determine the publication rate of abstracts presented at the annual meetings of the Arthroscopy Association of North America (AANA) from 2011 through 2014 and to compare the level of evidence (LoE) between published and unpublished studies. ⋯ The publication rate and level of evidence of podium presentations at AANA demonstrate the scientific impact the annual meeting has for peers pursuing orthopaedic research.
-
To compare the minimum 2-year outcomes and return to sports in competitive athletes after arthroscopic iliopsoas fractional lengthening (IFL) and treatment for femoroacetabular impingement (FAI) to competitive athletes treated for FAI who did not undergo IFL. ⋯ Level III, case-control study.

Editorial Commentary: Medial Patellofemoral Ligament Reconstruction for Knee Patellar Instability: When Are Soft Tissue Procedures Not Enough?
Medial patellofemoral ligament reconstruction is commonly performed to treat patellofemoral instability by recreating the static soft tissue restraint to lateral patellar translation. Concurrent tibial tuberosity osteotomy can be indicated in the setting of bony malalignment, such as a lateralized tuberosity or patella alta; however, the exact indications for this have been difficult to define due to the multifactorial nature of this problem. Understanding the role of tuberosity lateralization and patella alta on the function of medial patellofemoral ligament grafts can help to identify the interplay of some factors that contribute to patellar stability and improve our understanding of when and how concurrent tibial tuberosity osteotomy may be indicated.

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.
