Department of Orthopaedic Surgery, Musculoskeletal Research Center.

Purpose Of Review: The interaction between joint injuries and posttraumatic osteoarthritis (PTOA) is generally thought to be mechanical in nature, however, surgical intervention has little effect on the development of PTOA. Little is known about the biological underpinning of how meniscus and anterior cruciate ligament (ACL) tears lead to cartilage degeneration. This review summarizes the latest findings regarding biological factors that influence how the knee responds to meniscus and ligament injuries, how meniscus and/or ACL tears turn the joint in the direction of PTOA and whether patient risk for PTOA after meniscus/ACL injury can be predicted.

Human Cartilage-Derived Progenitors Resist Terminal Differentiation and Require CXCR4 Activation to Successfully Bridge Meniscus Tissue Tears.

Stem Cells 2019 Jan 2;37(1):102-114. Epub 2018 Nov 2.

Department of Orthopaedics, Brown University/Rhode Island Hospital, Providence, Rhode Island, USA.

Meniscus injuries are among the most common orthopedic injuries. Tears in the inner one-third of the meniscus heal poorly and present a significant clinical challenge. In this study, we hypothesized that progenitor cells from healthy human articular cartilage (chondroprogenitor cells [C-PCs]) may be more suitable than bone-marrow mesenchymal stem cells (BM-MSCs) to mediate bridging and reintegration of fibrocartilage tissue tears in meniscus.

Partial Meniscus Replacement with a Collagen-Hyaluronan Infused 3D Printed Polymeric Scaffold.

Tissue Eng Part A 2018 Oct 23. Epub 2018 Oct 23.

Rutgers Biomedical and Health Sciences - Robert Wood Johnson Medical School , Orthopaedic Surgery, New Brunswick, New Jersey, United States.

Meniscal lesions represent one of the most common orthopaedic injuries, and the standard of care, partial meniscectomy, often leads to long term joint deterioration. The current meniscal replacement devices fail to recreate the native meniscus biomechanics which may explain the uncertainty of their clinical efficacy. A biomechanically-functional, collagen-hyaluronan infused, 3D-printed polymeric scaffold was implanted into 18 sheep for up to 24 weeks to assess the scaffold's fixation, cellular response, tissue generation, integration to the host tissue, and effect on the surrounding articular cartilage.

A Single Bundle Anterior Cruciate Ligament Reconstruction (ACL-R) Using Hamstring Tendon Autograft and Tibialis Anterior Tendon Allograft: A Comparative Study.

Curr Med Sci 2018 Oct 20;38(5):818-826. Epub 2018 Oct 20.

Department of Orthopaedics, Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, Wuhan, 430022, China.

The main purpose of this study was to compare the clinical outcomes of patients undergoing a single bundle anterior cruciate ligament reconstruction (ACL-R) of using quadrupled hamstring (4HT) autografts and two-strand tibialis anterior (2TA) allografts, and to find out the rate of graft failure and possible causes. We hypothesized that there would be no difference in the clinical outcome, and graft failure would be associated with the use of small sized allograft in young active males with high demand of sports activities. We retrospectively evaluated 222 patients (male, n=167, female, n=55) undergoing ACL-R between January 2010 and July 2014. Read More

Radiol Clin North Am 2018 Nov 17;56(6):953-964. Epub 2018 Sep 17.

Department of Radiology, Medical University of South Carolina, 96 Jonathan Lucas Street, MSC 323, Charleston, SC 29425, USA. Electronic address:

In the postmeniscectomy or meniscal repair setting, there is overlap between expected postoperative change and findings of a re-torn meniscus, particularly increased T1-weighted or proton density signal contacting the articular surface. Protocol selection and accurate diagnosis requires knowledge of meniscal tear treatment, the expected postoperative appearance, and criteria for re-tear. Criteria for meniscal re-tear on MR imaging are high T2-weighted signal reaching the articular surface, abnormal meniscal morphology not explained by the surgery, or a displaced fragment. Read More

Department of Orthopaedic Surgery, Graduate School of Medicine, Kobe University, 7-5-1 Kusunoki-cho, Chuo-ku, Kobe, Hyogo, 650-0017, Japan.

Purpose: Concomitant meniscus injuries in the anterior cruciate ligament (ACL) have been suggested to exacerbate rotational laxity. However, the effect is supposed to be so small, if any, that some quantitative pivot-shift measurement is needed. The purpose of this prospective study was to determine the effect of meniscus tear on rotational laxity in ACL-deficient knees by an quantitative measurement. Read More
