    Editorial Commentary: When a Tie Is Still a Win: Systematic Reviews Showing No Difference Between Treatments May Not Be Generalizable to Individual Patients.
    Arthroscopy 2017 Nov;33(11):2093-2094
    When a systematic review finds no difference between treatment options for a particular disorder, this could mean more than you think. Individual patients requiring shoulder Bankart repair are unique with respect to their demands and expectations and pathology. Surgeons should combine published principles with understanding of their own skills and their specific patient to optimize a treatment outcome. Read More

    Editorial Commentary: Obese and Overweight: Should They Be Concerned About the Long-Term Consequences of a Partial Meniscectomy?
    Arthroscopy 2017 Nov;33(11):2064-2065
    Is obesity associated with inferior outcomes after partial meniscectomies? Recent research using data from the Chondral Lesions and Meniscus Procedures trial could not demonstrate any differences in obese and overweight patients compared with individuals with a normal body mass index. However, the inclusion of multiple confounders, and a short follow-up of only 1 year limit the validity of their study and the results must be viewed with great caution. Read More

    Editorial Commentary: Can the Outcomes of Microfracture Be Improved to Better Repair Small Cartilage Defects?
    Arthroscopy 2017 Nov;33(11):2052-2053
    The use of a cannulated hollow awl in the microfracture technique can prevent destruction of subchondral bone and potentially enhance the cartilage repair process. Further long-term clinical study would be required to confirm the efficacy of this procedure modification. Read More

    Editorial Commentary: Measuring Coronal (Mal)Alignment for Patients With Patellar Instability: Tibial Tubercle-to-Trochlear Groove Versus Tibial Tubercle-to-Posterior Cruciate Ligament Distance.
    Arthroscopy 2017 Nov;33(11):2035-2037
    The Johns Hopkins University.
    Excessive lateralization of the tibial tuberosity is one of the anatomic factors that contribute to lateral patellar instability, which we usually correct surgically with tibial tuberosity osteotomy. Traditionally, coronal alignment was determined clinically by measuring the Q angle, which has proven to be unreliable. Radiographic measurements of coronal alignment made using computed tomography and magnetic resonance imaging are more reliable and have become the standard for determining the need for corrective tibial tuberosity osteotomy.

    Editorial Commentary: Arthroscopic Simulation Training Need Not Be Expensive to Be Effective.
    Arthroscopy 2017 Nov;33(11):2024-2025
    In a randomized controlled trial of arthroscopic training tools, the low-cost/low-fidelity Cigar Box Arthroscopy Trainer demonstrated equivalent efficacy to the validated, and more expensive, Anatomic Knee Arthroscopy Trainer (AKAT) in the training of novice arthroscopists using a validated scoring system, the Basic Arthroscopic Knee Skill Scoring System. As simulation training and formal surgical skills training is now mandatory, residency and fellowship programs are required to incorporate training modules and equipment to maximize learning while minimizing potential for patient harm. Low-cost, low-fidelity simulation tools such as this may provide a solution to do so while minimizing costs and maximizing educational returns on investment. Read More

    Editorial Commentary: Beware the Radial Nerve: More Elbow Arthroscopy Portals, More Options.
    Arthroscopy 2017 Nov;33(11):1986-1987
    Mississippi Sports Medicine and Orthopaedic Center.
    Elbow arthroscopy is a challenging procedure due, in part, to the technical demands of portal placement as a consequence of the close proximity of the neurovascular structures. The radial nerve and its branches are especially at risk during lateral elbow arthroscopic portal placement. Two newly described (proximal) anterolateral elbow arthroscopy portals may be safer than the distal anterolateral portal location with regard to proximity to the radial nerve. Read More

    Editorial Commentary: You May Not Have Seen It, but It Has Seen You: Diagnosis of Long Head Biceps Tendon and Subscapularis Pathology in Association With Shoulder Rotator Cuff Pathology Can Be Challenging.
    Arthroscopy 2017 Nov;33(11):1977-1980
    Taos, NM.
    The shoulder can humble you. It is often challenging in determining the extent of pathology even when there is an adequate magnetic resonance imaging performed preoperatively and even during the so-called diagnostic portion of the arthroscopy. Abnormalities of the long head of the biceps tendon and the rotator cuff especially the subscapularis can be difficult to diagnose definitively. Read More

    Editorial Commentary: My Shoulder Feels Great, But Why Is My Thigh Numb? Lateral Femoral Cutaneous Nerve Injury After Shoulder Arthroscopy in the Beach Chair Position.
    Arthroscopy 2017 Nov;33(11):1963-1964
    Lateral femoral cutaneous nerve injury after shoulder arthroscopy in the beach chair position is an uncommon, but irritating complication for patients. Taking an extra minute to ensure a safe beach chair position will likely minimize the occurrence and prevent a disheartening conversation at the first postoperative visit. Read More

    Editorial Commentary: Partial (Shoulder Rotator) Cuff Repair: May the Force (Couple) Be With You.
    Arthroscopy 2017 Nov;33(11):1956-1957
    The Sports Clinic, Orthopedic Medical Associates, Inc.
    Partial repair of a shoulder rotator cuff tear, in the face of an otherwise massive or "irreparable" tear, is an effective treatment for reducing patient pain and improving function. Partial repair restores balance to the force couple composed of the infraspinatus and teres minor posteriorly and the subscapularis anteriorly. A balanced force couple maintains centralization of the humeral head on the glenoid during shoulder range of motion and, in nonarthritic patients with massive or irreparable tears, is better than no repair at all.

    Editorial Commentary: Is the Information Gathered From Patient-Reported Outcome Worth the Time and Effort? Electronic Patient-Reported Outcome Data Collection Systems Result in Poor Response Rate.
    Arthroscopy 2017 Nov;33(11):1947-1948
    There is an increasing demand for quality metrics and patient-reported outcomes from government agencies and insurance carriers. However, electronic patient-reported outcomes fail to achieve a significant response rate because they are too long and complicated. It is suggested that outcome scores for quality metrics need to be simplified to increase the response rate. Read More

    Editorial Commentary: The Long Head of the Biceps Brachii Tendon-The Shoulder Surgeon's Conundrum.
    Arthroscopy 2017 Nov;33(11):1937-1939
    The Rothman Institute, Thomas Jefferson University.
    The long head of the biceps tendon can be a significant pain generator in the setting of rotator cuff tearing. Surgeons who encounter long head of biceps tendon pathology at the time of rotator cuff repair can be confident in a high likelihood of statistically significant clinical improvement with concomitant long head of biceps surgery. Patients can be reliably counseled preoperatively that if they have both clinically apparent long head of biceps tendon pathology and rotator cuff tearing, and if they undergo long head of biceps tendon surgery with rotator cuff repair, they can expect comparable or better outcomes than isolated rotator cuff repair.

    Arthroscopic Training in the 21st Century: A Changing Paradigm.
    Arthroscopy 2017 Nov;33(11):1913-1915
    Although proficiency training will never completely replace the apprenticeship model, improvement in arthroscopic surgical-simulator technology permits students to spend less time observing and more time doing. The best models and simulators allow measurement and documentation of skill-based progression. Once basic skills have been satisfactorily demonstrated, trainees transitioning to actual operative arthroscopy should be expected to contribute to safer and more efficient patient care while continuing to learn and improve.

    Methods: We collected data on adult patients who underwent surgical repair for symptomatic full-thickness rotator cuff tears confirmed by imaging between 2012 and 2015. The required follow-up was 3 years. Read More

    Arthroscopic Debridement for Primary Degenerative Osteoarthritis of the Elbow Leads to Significant Improvement in Range of Motion and Clinical Outcomes: A Systematic Review.
    Arthroscopy 2017 Oct 31. Epub 2017 Oct 31.
    Houston Methodist Orthopedic and Sports Medicine, Houston, Texas, U.S.A.. Electronic address:
    Purpose: The purpose of this investigation was to determine whether arthroscopic debridement of primary elbow osteoarthritis results in statistically significant and clinically relevant improvement in (1) elbow range of motion and (2) clinical outcomes with (3) low complication and reoperation rates.

    Methods: A systematic review was registered with PROSPERO and performed using PRISMA guidelines. Databases were searched for studies that investigated the outcomes of arthroscopic debridement for the treatment of primary osteoarthritis of the elbow in adult human patients. Read More

    Computed Tomography Scans in Patients With Young Adult Hip Pain Carry a Lifetime Risk of Malignancy.
    Arthroscopy 2017 Oct 31. Epub 2017 Oct 31.
    Department of Orthopaedic Surgery, University of Utah, Salt Lake City, Utah, U.S.A.. Electronic address:
    Purpose: To calculate the lifetime risk of malignancy in young adult patients with hip pain using 5 different imaging and radiation dose protocols with or without pre- and postoperative computed tomography (CT).

    Methods: Radiographic and CT patient radiation doses were retrospectively reviewed. Imaging protocols for hip pain composed of radiographs with or without pre- and postoperative CT scans were modeled and radiation doses were estimated using the PCXMC computer code. Read More

    Arthroscopic Correction of the Critical Shoulder Angle Through Lateral Acromioplasty: A Safe Adjunct to Rotator Cuff Repair.
    Arthroscopy 2017 Oct 31. Epub 2017 Oct 31.
    Department of Orthopedics, Balgrist University Hospital, University of Zurich, Zurich, Switzerland; Department of Orthopedics and Traumatology, Paracelsus Medical University, Salzburg, Austria.
    Purpose: To investigate whether arthroscopic lateral acromioplasty reliably decreases the critical shoulder angle (CSA) and whether it is associated with damage to the deltoid or other complications.

    Methods: Patients undergoing arthroscopic rotator cuff repair (RCR) with lateral but without anterior acromioplasty for degenerative, full-thickness rotator cuff tears and a CSA of 34° or greater were retrospectively reviewed. Patients with traumatic or irreparable rotator cuff tears, osteoarthritis, or previous surgery were excluded. Read More

    Central Acetabular Impingement Is Associated With Femoral Head and Ligamentum Teres Damage: A Cross-sectional Matched-Pair Analysis of Patients Undergoing Hip Arthroscopy for Acetabular Labral Tears.
    Arthroscopy 2017 Oct 31. Epub 2017 Oct 31.
    American Hip Institute, Westmont, Illinois, U.S.A.; Hinsdale Orthopaedics, Westmont, Illinois, U.S.A.. Electronic address:
    Purpose: The primary purpose of this study was to report the prevalence of femoral head articular damage in patients with a central acetabular osteophyte (CAO) that was identified during hip arthroscopy and compare it with that in a matched control group without a CAO. A secondary purpose was to identify rates of coexisting intra-articular pathology in both patient groups.

    Methods: Intraoperative data were collected prospectively on all hip arthroscopy patients at our institution between 2008 and 2015. Read More

    Effect of Transosseous Tunnels on Patella Fracture Risk After Medial Patellofemoral Ligament Reconstruction: A Cadaveric Study.
    Arthroscopy 2017 Oct 31. Epub 2017 Oct 31.
    Department of Orthopaedics and Rehabilitation, Milton S. Hershey Medical Center, Penn State Health, Hershey, Pennsylvania, U.S.A.. Electronic address:
    Purpose: To determine whether (1) tunnels that breach the anterior cortex of the patella result in increased fracture risk and (2) transosseous tunnels drilled across the patella significantly reduce the tensile force needed to fracture the patella.

    Methods: Twenty-six fresh-frozen cadaveric human patellas were randomized to 1 of 3 groups: a control group with unmodified patellas, a group with 2 transverse tunnels (TT) that did not breach the anterior cortex, and a group with 2 TT that breached the anterior cortex of the patella (PA). Patellas were connected in series to a load cell via freeze clamp attachments to the quadriceps and patellar tendons. Read More
