Systematic Review of Elbow Instability in Association With Refractory Lateral Epicondylitis: Myth or Fact?

期刊: AMERICAN JOURNAL OF SPORTS MEDICINE, 2021; 49 (9)

Background: Elbow instability, particularly posterolateral rotatory instability (PLRI), has been reported in patients with refractory lateral epicondy......

Effect of Exercise Intensity on the Healing of the Bone-Tendon Interface: A Mouse Rotator Cuff Injury Model Study

期刊: AMERICAN JOURNAL OF SPORTS MEDICINE, 2021; 49 (8)

Background: Injuries at the bone-tendon interface (BTI) are common findings in clinical practice. Rehabilitation procedures after BTI surgery are impo......

Intra-articular Injection of Kartogenin-Enhanced Bone Marrow-Derived Mesenchymal Stem Cells in the Treatment of Knee Osteoarthritis in a Rat Model

期刊: AMERICAN JOURNAL OF SPORTS MEDICINE, 2021; 49 (10)

Background: In this study, we investigated the in vitro and in vivo chondrogenic capacity of kartogenin (KGN)-enhanced bone marrow-derived mesenchymal......

The Effect of Antiosteoporosis Therapy With Risedronate on Rotator Cuff Healing in an Osteoporotic Rat Model

期刊: AMERICAN JOURNAL OF SPORTS MEDICINE, 2021; 49 (8)

Background: Osteoporosis increases the revision rate of rotator cuff repair (RCR). Weak fixation might not be the only cause of high RCR failure rates......

Cell-Free Book-Shaped Decellularized Tendon Matrix Graft Capable of Controlled Release of BMP-12 to Improve Tendon Healing in a Rat Model

期刊: AMERICAN JOURNAL OF SPORTS MEDICINE, 2021; 49 (5)

Background: Achilles tendon (AT) defects often occur in traumatic and chronic injuries. Currently, no graft can satisfactorily regenerate parallel ten......

Scaffold With Natural Calcified Cartilage Zone for Osteochondral Defect Repair in Minipigs

期刊: AMERICAN JOURNAL OF SPORTS MEDICINE, 2021; 49 (7)

Background: Long-term outcomes of current clinical interventions for osteochondral defect are less than satisfactory. One possible reason is an ignora......

Increased Posterior Tibial Slope Is Associated With Greater Risk of Graft Roof Impingement After Anatomic Anterior Cruciate Ligament Reconstruction

期刊: AMERICAN JOURNAL OF SPORTS MEDICINE, 2021; 49 (9)

Background: Increased posterior tibial slope (PTS) has been reported to be associated with irreducible anterior tibial subluxation in extension after ......

Adipose Stem Cell-Derived Exosomes Ameliorate Chronic Rotator Cuff Tendinopathy by Regulating Macrophage Polarization: From a Mouse Model to a Study in Human Tissue

期刊: AMERICAN JOURNAL OF SPORTS MEDICINE, 2021; 49 (9)

Background: Chronic rotator cuff (RC) tendinopathy is one of the most prevalent causes of shoulder pain. Growing evidence suggests that macrophages pl......

Posterior Tibial Loading Results in Significant Increase of Peak Contact Pressure in the Patellofemoral Joint During Anterior Cruciate Ligament Reconstruction: A Cadaveric Study

期刊: AMERICAN JOURNAL OF SPORTS MEDICINE, 2021; 49 (5)

Background: Inappropriate posterior tibial loading and initial graft tension during anterior cruciate ligament (ACL) reconstruction may cause altered ......

Hierarchically Demineralized Cortical Bone Combined With Stem Cell-Derived Extracellular Matrix for Regeneration of the Tendon-Bone Interface

期刊: AMERICAN JOURNAL OF SPORTS MEDICINE, 2021; 49 (5)

Background: Poor healing of the tendon-bone interface after rotator cuff repair is one of the main causes of surgical failure. Previous studies demons......

Evaluation of Cam Deformity on 3-Dimensional Computed Tomography With the Best-Fit Sphere Technique and the Alpha Angle Marking Method

期刊: AMERICAN JOURNAL OF SPORTS MEDICINE, 2021; 49 (4)

Background: Three-dimensional computed tomography (3D-CT) is commonly used for the evaluation of cam deformity; however, it does not display the cam b......

The Enhancement Effect of Acetylcholine and Pyridostigmine on Bone-Tendon Interface Healing in a Murine Rotator Cuff Model

期刊: AMERICAN JOURNAL OF SPORTS MEDICINE, 2021; 49 (4)

Background: How to improve rotator cuff healing remains a challenge. Little is known about the effect of the parasympathetic transmitter acetylcholine......

Adipose Stem Cell-Derived Exosomes Recover Impaired Matrix Metabolism of Torn Human Rotator Cuff Tendons by Maintaining Tissue Homeostasis

期刊: AMERICAN JOURNAL OF SPORTS MEDICINE, 2021; 49 (4)

Background: Adipose stem cell-derived exosomes (ASC-Exos) are reported to effectively prevent muscle atrophy and degeneration of torn rat rotator cuff......

Functional, Magnetic Resonance Imaging, and Second-Look Arthroscopic Outcomes After Pullout Repair for Avulsion Tears of the Posterior Lateral Meniscus Root

期刊: AMERICAN JOURNAL OF SPORTS MEDICINE, 2021; 49 (2)
