Orchestrated biomechanical, structural, and biochemical stimuli for engineering anisotropic meniscus.

Sci Transl Med 2019 Apr;11(487)

Knee Surgery Department of the Institute of Sports Medicine, Beijing Key Laboratory of Sports Injuries, Peking University Third Hospital, Beijing 100191, P.R. China.

Reconstruction of the anisotropic structure and proper function of the knee meniscus remains an important challenge to overcome, because the complexity of the zonal tissue organization in the meniscus has important roles in load bearing and shock absorption. Current tissue engineering solutions for meniscus reconstruction have failed to achieve and maintain the proper function in vivo because they have generated homogeneous tissues, leading to long-term joint degeneration. To address this challenge, we applied biomechanical and biochemical stimuli to mesenchymal stem cells seeded into a biomimetic scaffold to induce spatial regulation of fibrochondrocyte differentiation, resulting in physiological anisotropy in the engineered meniscus.

A Versatile Protocol for Studying Anterior Cruciate Ligament Reconstruction in a Rabbit Model.

Tissue Eng Part C Methods 2019 Apr;25(4):191-196

1 Department of Orthopedic Surgery, Mayo Clinic, Rochester, Minnesota.

Anterior cruciate ligament (ACL) injuries are frequent, as >200,000 injuries occur in the United States alone each year. Owing to the risks for associated meniscus and cartilage damage, ACL injuries are a significant source of both orthopedic care and research. Given the extended recovery course after ACL injury, which often lasts 1-2 years, and is associated with limited participation in sports and activities of daily living for patients, there is a critical need for the evolution of new and improved methods for ACL repair.

Authors:
Aaron K Black

Arthroscopy 2019 Mar;35(3):938-939

Silverthorne, Colorado.

As the understanding of the intrinsic reliance of the anterior cruciate ligament on the medial collateral ligament (MCL) has grown, we have delved further into trying to understand what specific function needs to be restored in their combined injury. At the same time, we have expanded our knowledge of the relation between the MCL and the medial meniscus. It is a great step forward for our knowledge to begin to infer medial stability from the status of the medial meniscus in these complex cases. Read More

Biomechanical characterization of a novel collagen-hyaluronan infused 3D-printed polymeric device for partial meniscus replacement.

J Biomed Mater Res B Appl Biomater 2019 Feb 18. Epub 2019 Feb 18.

Department of Orthopaedic Surgery, Rutgers Biomedical and Health Sciences - Robert Wood Johnson Medical School, New Brunswick, New Jersey, USA.

The menisci transmit load by increasing the contact area and decreasing peak contact stresses on the articular surfaces. Meniscal lesions are among the most common orthopedic injuries, and resulting meniscectomies are associated with adverse polycaprolactone contact mechanics changes and, ultimately, an increased likelihood of osteoarthritis. Meniscus scaffolds were fabricated by 3D-printing a network of circumferential and radial filaments of resorbable polymer (poly(desaminotyrosyl-tyrosine dodecyl ester dodecanoate)) and infused with collagen-hyaluronan.

Accelerated Knee Osteoarthritis is Characterized by Destabilizing Meniscal Tears and Pre-Radiographic Structural Disease Burden.

Arthritis Rheumatol 2018 Dec 28. Epub 2018 Dec 28.

Division of Rheumatology, Tufts Medical Center, 800 Washington StreetTufts Med Ctr #406, 02111, Boston, Massachusetts, United States.

Objective: To determine if accelerated knee osteoarthritis (KOA) is preceded and characterized by destabilizing meniscal tears or other pathologic changes.

Methods: We selected 3 sex-matched groups from the first 48 months of the Osteoarthritis Initiative who had a knee without KOA at baseline (Kellgren-Lawrence [KL]<2): Accelerated KOA (AKOA) developed KL grade≥3, typical KOA increased radiographic scoring, and no KOA had the same KL grade over time. An index visit was the visit when the radiographic criteria for AKOA and typical KOA were met (no KOA was matched to AKOA). Read More

Isolated revision meniscal repair - failure rates, clinical outcome, and patient satisfaction.

BMC Musculoskelet Disord 2018 Dec 21;19(1):446. Epub 2018 Dec 21.

Department of Orthopedic Surgery and Traumatology, Freiburg University Hospital, Albert Ludwigs University Freiburg, Hugstetter Straße 55, 79106, Freiburg, Germany.

Background: Failure of isolated primary meniscal repair must be expected in approximately 10-25% of cases. Patients requiring revision surgery may benefit from revision meniscal repair, however, the results of this procedure remain underreported. The purpose of this study was therefore to evaluate the outcome and failure rates of isolated revision meniscal repair in patients with re-tears or failed healing after previous meniscal repair in stable knee joints.

Healthc Technol Lett 2018 Dec 14;5(6):247-249. Epub 2018 Nov 14.

Department of Physical Education, Central South University of Forestry and Technology, Changsha, Hunan 410004, People's Republic of China.

The knee joint is one of the most important joints in the human body. The meniscus is a half-moon cartilage which locates between the medial and lateral condyle of the thighbone and the medial and lateral condyle of the shin in the knee joint, and it has multiple functions such as bearing load, cushioning and stabilising joints. It is easy to be injured because of its complex structure and functions. Read More

High short-term return to sports rate despite an ongoing healing process after acute meniscus repair in young athletes.

Knee Surg Sports Traumatol Arthrosc 2019 Jan 11;27(1):215-222. Epub 2018 Dec 11.

Department of Orthopaedic Sports Medicine, Klinikum Rechts der Isar, Technical University Munich, Ismaningerstr. 22, 81675, Munich, Germany.

Purpose: Acute meniscus repair in young athletes is always a challenge due to the long rehabilitation process and time to return to sport (RTS). The purpose was to investigate signal alterations in short-term follow-up after acute meniscus repair on specific magnetic resonance imaging (MRI) scan sequences. It was hypothesized that (1) MRI signal changes over the first postoperative healing phase and represent a continuous healing process and (2) meniscus healing properties correlates with clinical outcomes and RTS.

The TeMPO trial (treatment of meniscal tears in osteoarthritis): rationale and design features for a four arm randomized controlled clinical trial.

BMC Musculoskelet Disord 2018 Dec 1;19(1):429. Epub 2018 Dec 1.

Orthopaedic and Arthritis Center for Outcomes Research (OrACORe) and Policy and Innovation eValuation in Orthopedic Treatments (PIVOT), Department of Orthopaedic Surgery, Brigham and Women's Hospital, 60 Fenwood Road, BTM 5016, Boston, MA, 02115, USA.

Background: Meniscal tears often accompany knee osteoarthritis, a disabling condition affecting 14 million individuals in the United States. While several randomized controlled trials have compared physical therapy to surgery for individuals with knee pain, meniscal tear, and osteoarthritic changes (determined via radiographs or magnetic resonance imaging), no trial has evaluated the efficacy of physical therapy alone in these subjects.

Methods: The Treatment of Meniscal Tear in Osteoarthritis (TeMPO) Trial is a four-arm multi-center randomized controlled clinical trial designed to establish the comparative efficacy of two in-clinic physical therapy interventions (one focused on strengthening and one containing placebo) and two protocolized home exercise programs.

Discoid meniscus in children and adolescents: Correlation between morphology and meniscal tears.

Rev Esp Cir Ortop Traumatol 2019 Jan - Feb;63(1):24-28. Epub 2018 Nov 24.

Departamento de Ortopedia y Traumatología Infantil, Sanatorio Allende, Córdoba, Argentina.

Background: Some authors have suggested that the diminished vascular blood supply, peripheral stability and thickness of the discoid meniscus (DM) would make it more prone to tears. The aims of this study are two-fold: 1) To analyse morphological characteristics by magnetic resonance (MRI), and 2) To correlate the size of the meniscus with the presence of meniscal tears.

Methods: The MRI of patients ≤18 years-old over a period of 5 years were reviewed, and patients with DM were identified. Read More
