    Editorial Commentary: The Partial Thickness Rotator Cuff Tear: Is Acromioplasty Without Repair Ever Indicated?
    Arthroscopy 2018 Jan;34(1):82-83
    Hospital for Special Surgery and Weill Cornell Medicine.
    I believe that arthroscopic repair is the treatment of choice for patients with partial thickness rotator cuff tears when nonoperative methods have been exhausted. Excluding overhead athletes and patients in whom long head biceps tendon pathology is the primary concern, I do not believe that a significant role exists for debridement with or without acromioplasty in the majority of patients with partial thickness tears. Regarding the repair technique, I prefer in situ repair for bursal-sided tears because the superior capsule is intact and completion of the tear with repair for articular-sided tears. Read More

    Editorial Commentary: MRI Findings Are Only One Part of the Equation in National Football League Athletes: Shoulder Instability in Contact Athletes.
    Arthroscopy 2018 Jan;34(1):73-74
    University of Pittsburgh Medical Center.
    Shoulder instability is a common problem in contact sports such as the National Football League. Although many elite level football athletes will have shoulder magnetic resonance imaging (MRI) findings consistent with labral tearing on MRI, these imaging findings are not always correlated with symptomatic instability or functional limitations. It is crucial in all patients, not just National Football League athletes, to treat the patient, and not the MRI. Read More

    Editorial Commentary: "Knot" Less Strength at Half the Cost-Is It Time to Abandon Medial Row Anchors in Shoulder Double-Row Rotator Cuff Repair?
    Arthroscopy 2018 Jan;34(1):64-65
    Transosseous equivalent rotator cuff repair is an expensive construct that has demonstrated biomechanical superiority when compared with other rotator cuff repair techniques. A novel transosseous knotless repair that substitutes medial row anchors for a transosseous tunnel rivals the biomechanical advantages of transosseous equivalent rotator cuff repair at half the cost and with reduced dependence on bone quality. Surgeons should carefully consider if "knotless transosseous is more. Read More

    Editorial Commentary: Don't Pig Out When Selecting a Shoulder, Rotator Cuff Augmentation Graft! Xenografts Are Not the Way to Go.
    Arthroscopy 2018 Jan;34(1):38-40
    Porcine xenograft dermal onlay augmentation of rotator cuff repair does not provide improved cuff integrity or provide better clinical outcomes. The retear rate was actually higher in repairs augmented with a porcine xenograft than the control group. Adverse events occurred in 60% of the xenograft patients compared with 40% of the controls. Read More

    Editorial Commentary: Animal Trials Using Stem Cells to Enhance Anterior Cruciate Ligament Treatment Are Interesting. But, Why Not More About Us Humans?
    Arthroscopy 2018 Jan;34(1):343-344
    Although hampered by heterogeneous studies with low methodologic quality and high risk for bias, the current literature demonstrates the potential for enhanced healing of anterior cruciate ligament injuries during the early phase using adult stem cells in animal trials. There are only 2 published controlled clinical trials on the subject matter, and they have small sample sizes, undefined cell numbers, and unstandardized selection criteria and surgical techniques. There is a clear need for studies with higher levels of evidence that would include long-term, larger animal studies ultimately leading to improved clinical trials. Read More

    Editorial Commentary: Adult Stem Cell Potential to Enhance Healing of the Anterior Cruciate Ligament.
    Arthroscopy 2018 Jan;34(1):341-342
    University of Pittsburgh Medical Center.
    Even with the most accurate individualized, anatomic approach to anterior cruciate ligament (ACL) reconstruction, the potential for graft failure still exists, with reported retear rates as low as 5%, and even higher in female athletes or patients reconstructed with allograft. ACL graft healing is dependent on several factors, including anatomic placement, appropriate graft choice, proper technique, recovery time, and the biological environment of nature. If the double-bundle concept is followed and individualized for each patient's anatomic morphology, the ACL will biologically reform. Read More

    Editorial Commentary: Not Repairing the Hip Capsule After Arthroscopy-What Were We Thinking?
    Arthroscopy 2018 Jan;34(1):319-320
    Stanford University/VA Palo Alto.
    There has been an exponential increase in attention paid to the hip capsule as it relates to arthroscopic procedures. Violation of the hip capsule during arthroscopy has clear biomechanical consequences for the joint, and evidence that the capsule should be repaired following most arthroscopic hip procedures, and also in revision settings, is becoming insurmountable.

    Editorial Commentary: Revision Knee Anterior Cruciate Ligament Reconstruction: Failure Rates Appear to Have Declined yet Different Research Methods Could Show Different Results.
    Arthroscopy 2018 Jan;34(1):301-302
    In the past decade there has been a rapid expansion in the available evidence for outcomes after revision knee anterior cruciate ligament reconstructions including data from 2 large registries and a growing body of research. The advent of 2 large registries and a growing body of evidence have provided a refined view of failure after revision reconstruction. A careful review of this evidence indicates that failure rates are not as high as previously reported in the literature. Read More

    Editorial Commentary: Internet Resources for Platelet-Rich Plasma: An Electronic Repository of "Alternative Facts"?
    Arthroscopy 2018 Jan;34(1):279-280
    Hospital for Special Surgery and Weill Cornell Medicine.
    Information about platelet-rich plasma available on the Internet is of poor quality, low accuracy, and difficult to read. But we can do better. Before consultation or as part of the informed consent process, surgeons can direct patients to prescreened, commercial-free information published in a peer-reviewed manner by authoritative third-party specialty societies.

    Editorial Commentary: The Amsterdam Achilles Tendinopathy Endoscopic Treatment: Should We Start Booking Our Patients for Surgery?
    Arthroscopy 2018 Jan;34(1):270-271
    Mid-portion Achilles tendinopathy remains an elusive clinical and pathologic condition, with only a limited treatment algorithm to guide us. Although the risk factors and natural history have been documented, the exact etiology and source of pain generation remains unclear in the literature. Several Level I studies have shown reasonable success with a myriad of nonoperative treatments over the long term. Read More

    Editorial Commentary: Filling the Void in Translational Research for Lateral Extra-articular Tenodesis for Anterior Cruciate Ligament Reconstruction: Are We Saturated With Biomechanical Studies?
    Arthroscopy 2018 Jan;34(1):261-263
    Columbia, Missouri.
    Anterior cruciate ligament (ACL) graft failure rates remain unacceptably high in certain populations, and researchers are examining the effect that the anterolateral ligament (ALL) has on knee stability following ACL reconstruction. Currently, most available research examining the ALL has focused on cadaveric biomechanical kinematic studies, including the effect of surgical techniques for ALL reconstruction/lateral extra-articular tenodesis (LET). However, it is critical for ongoing and future research to focus on clinical outcome measures relating to individuals who have had ALL reconstruction or LET along with their ACL reconstructions.

    Editorial Commentary: Prognosticators for Outcomes After Anterior Cruciate Ligament Reconstruction…Time to Beat a Different Dead Horse?
    Arthroscopy 2018 Jan;34(1):231-232
    Bishop, California.
    The outcomes of anterior cruciate ligament reconstruction, be it single or double bundle, continue to be analyzed with exhaustion. There is strong evidence regarding the measurable effects of femoral tunnel position as well as the contributions that age, time to surgery, and concomitant pathology have on outcomes of this procedure. We are surgeons with big egos. Read More

    Editorial Commentary: We Need to Customize Surgical Treatment When Treating Patients With Recurrent Anterior Shoulder Instability.
    Arthroscopy 2018 Jan;34(1):21-23
    University Medical Center of Princeton, New Jersey.
    Surgical repair of shoulder instability is challenging, and multiple procedures have been proposed. In an attempt to reduce risk of recurrence following surgical reconstruction, some surgeons have added steps to prior arthroscopic procedures, and other surgeons have selected a bone reinforcement procedure. These additional augmented repair techniques have reduced the risk of postoperative recurrence, but introduced additional risk of complications related to hardware, fixation, and possible need for additional surgery.

    Editorial Commentary: Are Knee Patellofemoral Surgeons Overestimating Their Anteromedialization Measurements?
    Arthroscopy 2018 Jan;34(1):198-199
    Indianapolis, Indiana.
    Anteromedialization as originally described by Fulkerson has become an important tool in the armamentarium of patellofemoral surgeons. The goal is to combine the unloading of tibial tubercle anteriorization and the realignment of tubercle medialization. The classic teaching, that the steepest slope of 60° allows approximately 9 mm of medialization with 15 mm of unloading anteriorization, is now challenged, and we may not be achieving the amount of anteriorization as preoperatively planned.

    Editorial Commentary: Three-Dimensional Printing and Stem Cells May Be a Game Changer for Recovery After Anterior Cruciate Ligament Reconstruction.
    Arthroscopy 2018 Jan;34(1):180-181
    Glen Allen, Virginia.
    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. Read More

    Arthroscopy 2018 Jan;34(1):152-154
    Cambridge and London, England.
    The ligamentum teres (LT) is perceived to contribute to hip stability and proprioception. LT incompetence can lead to pain and instability, which may play a role in chondral damage. Hip arthroscopy plays a role in diagnosing and treating LT tears. Read More

    Editorial Commentary: Proximal Hamstring Syndrome: Another Pain in the Buttock.
    Arthroscopy 2018 Jan;34(1):122-125
    Marina del Rey, California.
    Proximal hamstring injuries cause buttock pain and may result in significant weakness and sciatic neuralgia. Avulsion ruptures involving 2 or more tendons with >2-cm retraction may benefit from early open surgical repair. More chronic equivalents may benefit from Achilles allograft reconstruction.

    Editorial Commentary: It's the Fracture, Not the Fragment, That Causes the Pain: Posteromedial Elbow Impingement in Baseball Players.
    Arthroscopy 2018 Jan;34(1):111-113
    Rochester, Minnesota.
    Posterior impingement pain in baseball players is typically due to a fractured olecranon osteophyte. Computed tomographic (CT) scanning is the imaging of choice when evaluating posterior or posteromedial elbow pain in athletes who have subjected the elbow to excessive stresses such as occur in overhead throwing and weightlifting. Sometimes the fracture fragment can be so small that it might not be detected on plain radiographs, magnetic resonance imaging, or even at the time of arthroscopy. Read More

    Editorial Commentary: Superior Capsule Reconstruction With Dermal Allograft: Effective Marketing or the Real Deal?
    Arthroscopy 2018 Jan;34(1):102-104
    The young patient with a massive, irreparable rotator cuff tear is a challenging problem. Not only is this patient population demanding, but of the few surgical options that exist to manage this problem, each have their own unique limitations; as such, the orthopaedic community continues to search for a treatment that maximizes outcome and durability, while minimizing risk and preserving the native shoulder. Over the past few years, there has been considerable interest in a new surgical technique: the superior capsule reconstruction (SCR). Read More

    Editorial Commentary: Superior Capsule Reconstruction: Graft Healing for Success.
    Arthroscopy 2018 Jan;34(1):100-101
    Osaka Medical College.
    In my experience, after superior capsule reconstruction for irreparable rotator cuff tears, if the graft heals, we can expect a successful outcome, such as an American Shoulder and Elbow Surgeons score of more than 90 points and a visual analog scale score of less than 1.0. To decrease the graft tear rate after surgery, I have found that a thicker, stiffer graft than can be achieved with a dermal allograft alone is required to restore superior stability in the glenohumeral joint.
