Center for Materials Synthetic Biology, CAS Key Laboratory of Quantitative Engineering Biology, Shenzhen Institute of Synthetic Biology, Shenzhen Institutes of Advanced Technology, Chinese Academy of Sciences, Shenzhen, 518055, China.

Meniscal injuries have poor intrinsic healing capability and are associated with the development of osteoarthritis. Decellularized meniscus extracellular matrix (mECM) has been suggested to be efficacious for the repair of meniscus defect. However, main efforts to date have been focused on the concentration, crosslinking density and anatomical region dependence of the mECM hydrogels on regulation of proliferation and differentiation of adult mesenchymal stem cells (MSCs) 2D or 3D culture.

Deep MCL injury cases with arthroscopic findings of hypermobile medial meniscus: A report of six cases of arthroscopic meniscal suture repair.

Asia Pac J Sports Med Arthrosc Rehabil Technol 2020 Oct 9;22:1-4. Epub 2020 Jun 9.

Department of Sports Orthopedic Surgery, Kanto Rosai Hospital, 1-1 Kizuki Sumiyoshi-cho, Nakahara-ku, Kawasaki city, Kanagawa-pref, Japan.

MRI did not detect any abnormality in the medial meniscus besides high-intensity changes at the meniscofemoral portion of the deep medial collateral ligament. Although pure valgus stress test proved no medial joint widening at 0° and 30°, when an examiner applied knee valgus and tibial external rotation force, the patient experienced pain in the anteromedial knee joint that coincided with their refractory symptoms in individual specific activity. Arthroscopy investigation confirmed that the anterior to middle segment of the medial meniscus had excessively slid into the central direction by a probe-drawing manoeuvre; synchronous meniscal movement in the valgus and external rotation test was also observed.

Posterolateral approach for all-inside arthroscopic lateral meniscus repair in athletes: technique and outcomes.

Arch Orthop Trauma Surg 2020 Jun 7. Epub 2020 Jun 7.

Ramsay Générale de Santé, Hôpital privé Jean Mermoz, Centre Orthopédique Santy, FIFA Medical Centre of Excellence, 24 Avenue Paul Santy, 69008, Lyon, France.

Introduction: The past 2 decades have been marked by substantial progress in our knowledge of meniscus anatomy, function, and biomechanics, and also by the shifting of the surgical treatment of meniscal lesions from traditional meniscectomy towards arthroscopic repair to get away from the early osteoarthritis associated with meniscectomy. Posterior horn injuries of the lateral meniscus (LM) have been less studied due to their lower incidence and also due to the historical technical complexity of performing a repair in the posterolateral compartment.

Materials And Methods: A retrospective analysis of prospectively collected data was performed of all athletic patients who had a peripheral longitudinal tear of the lateral meniscal posterior horn and who underwent at least one repair procedure with a posterolateral approach between 2014 and 2018.

Editorial Commentary: Platelet-Rich Plasma and Knee Meniscal Repair-The Use of Biologics Has Not Progressed Substantially Since 1983.

Authors:
Jason Dragoo

Arthroscopy 2020 06;36(6):1775-1776

Stanford University.

When it comes to meniscal repair, optimizing the local biological environment at the repair site by performing trephination to create bleeding from the extracapsular capillary network, by rasping to abrade the local synovial tissue, or by creating bleeding from the intercondylar notch is recommended. The addition of platelet-rich plasma probably also helps, especially absent the bleeding when meniscal repair is performed concomitantly with anterior cruciate ligament reconstruction. However, pending future research, there is not enough data to recommend platelet-rich plasma augmentation for meniscal repair in all cases. Read More

Biomechanically, structurally and functionally meticulously tailored polycaprolactone/silk fibroin scaffold for meniscus regeneration.

Theranostics 2020 6;10(11):5090-5106. Epub 2020 Apr 6.

Institute of Sports Medicine, Beijing Key Laboratory of Sports Injuries, Peking University Third Hospital, 49 North Garden Road, Haidian District, Beijing 100191, People's Republic of China.

Meniscus deficiency, the most common and refractory disease in human knee joints, often progresses to osteoarthritis (OA) due to abnormal biomechanical distribution and articular cartilage abrasion. However, due to its anisotropic spatial architecture, complex biomechanical microenvironment, and limited vascularity, meniscus repair remains a challenge for clinicians and researchers worldwide. In this study, we developed a 3D printing-based biomimetic and composite tissue-engineered meniscus scaffold consisting of polycaprolactone (PCL)/silk fibroin (SF) with extraordinary biomechanical properties and biocompatibility.

Editorial Commentary: Meniscal Repair-Why Bother?

Authors:
Erik Hohmann

Arthroscopy 2020 04;36(4):1154-1155

Whether to repair or resect meniscal tears remains a matter of controversy. In theory, partial meniscectomy increases contact pressure, which may result in progressive and early cartilage degeneration and early osteoarthritis. Meniscal preservation is the preferred treatment option, but only a small percentage of meniscal tears are suitable for repair. Read More

Editorial Commentary: Comparing Medial and Lateral Meniscal Root Tears Is Like Comparing Apples and Oranges.

Arthroscopy 2020 04;36(4):1142-1144

Edina, Minnesota.

The importance of treating meniscal root tears has been increasingly recognized, and surgeons have to make conscious decisions routinely regarding repair for select patients. The clinical and patient demographic differences between medial and lateral meniscal root tears are important and ultimately leave us wondering whether outcome differences are due to unique anatomic factors or the patient population sustaining these injuries.

Arthroscopy 2020 04;36(4):1083-1085

Cambridge University Hospitals.

When considering repair of the meniscal cartilages of the knee, the indications for repair must be carefully considered. The morphology of the tear, the zone of injury, and likely vascularity have an impact on patient selection. Patient factors, chronicity of tear, medial or lateral tear, and tear complexity all have a bearing on whether to repair or resect and how best to achieve stable repair. Read More
