    Editorial Commentary: Retrograde Femoral Nail Malpositioning Can Destroy Knee Cartilage.
    Arthroscopy 2017 Sep;33(9):1731-1732
    Retrograde femoral nail malpositioning can obviously destroy knee trochlear cartilage. A solution is osteochondral allograft transplantation surgery. Although case reports are rarely published in Arthroscopy, we make an exception and publish a report of 2 cases of this complication (and how to treat it) because exposure of complications that have not been previously well-reported could allow future surgeons, and their patients, to solve-and, preferably, proactively avoid-similar problems.

    Editorial Commentary: The Ribbon Theory. Another Quantum Leap? The Anterior Cruciate Ligament Is Twisted and in Fact a Flat Structure. Or not?
    Arthroscopy 2017 Sep;33(9):1710-1711
    Is the double bundle structure of the anterior cruciate ligament (ACL) a myth? Derotation untwists the ACL and results in a flat ribbon structure. However, other researchers dispute this theory and revealed 2 distinct bundles separated by a synovial septum. The answer is simple: we do not know and the evidence is conflicting. Read More

    Editorial Commentary: Fixation of Soft-Tissue Anterior Cruciate Ligament Grafts in Osteoporotic Bone.
    Arthroscopy 2017 Sep;33(9):1701-1702
    University of California, Los Angeles.
    Tibial-side fixation of soft-tissue grafts in osteoporotic bone has become an important concern, as anterior cruciate ligament reconstruction indications push toward older patients. Although soft-tissue fixation with an interference screw and cortical button may be statistically stronger than graft fixation with a screw or button alone, this hybrid construct is probably not optimized from a clinical perspective.

    Editorial Commentary: Pitching a New Curve: Identifying the Etiology of Nontraumatic Throwing Injuries.
    Arthroscopy 2017 Sep;33(9):1637-1638
    Loss of shoulder motion, especially to flexion and external rotation, may increase the risk of nontraumatic shoulder and elbow injuries in elite pitchers. However, the etiology of these injuries is likely mulitifactorial, and before we direct our therapists to abandon sleeper stretches in favor of flexion and external rotation exercises, further research is needed to keep pitchers off the disabled list and on the mound.

    Getting Back to Basics: The "Primary" Outcome Measure Determines a Study's Conclusion.
    Arthroscopy 2017 Sep;33(9):1609-1610
    In this month's issue, Hollman, Wolterbeek, Zijl, van Egeraat, and Wessel from Nieuwegein, The Netherlands, investigate an essential and most basic concern: how does an abduction brace compare to a simple sling after arthroscopic rotator cuff repair? A criticism of the study, well noted in Editorial Commentary by Kevin Plancher, is that Hollman et al. selected postoperative pain (rather than long-term clinical outcome) as their "primary" outcome measure. The primary outcome measure determines the conclusion of a study. Read More
