Medial Knee Arthrosis: A Pathology with a Progressive Evolution.

Rev Bras Ortop (Sao Paulo) 2021 Apr 22;56(2):133-137. Epub 2020 Jul 22.

Departamento de Ortopedia e Traumatologia, Faculdade de Medicina, Universidade de São Paulo, São Paulo, SP, Brasil.

Medial arthrosis of the knee is an evolutionary pathology that occurs due to progressive muscle imbalance. The muscles of the knee region have a large imbalance caused by the difference of power and lever arm. With the progression of life, this imbalance manifests itself more importantly, especially due to the loss of muscle strength due to aging. Read More

Treadmill Exercise after Controlled Abnormal Joint Movement Inhibits Cartilage Degeneration and Synovitis.

Life (Basel) 2021 Apr 1;11(4). Epub 2021 Apr 1.

Department of Physical Therapy, Health and Social Services, Saitama Prefectural University, Koshigaya, Saitama 343-8540, Japan.

Cartilage degeneration is the main pathological component of knee osteoarthritis (OA), but no effective treatment for its control exists. Although exercise can inhibit OA, the abnormal joint movement with knee OA must be managed to perform exercise. Our aims were to determine how controlling abnormal joint movement and treadmill exercise can suppress cartilage degeneration, to analyze the tissues surrounding articular cartilage, and to clarify the effect of treatment.

Editorial Commentary: The Ratio of Tibial Slope and Meniscal Bone Angle is a Strong Predictor for Anterior Cruciate Ligament Injury: A Steep Hill and a Shallow Speed Bump are a Hazardous Combination.

Arthroscopy 2021 May;37(5):1610-1611

Auckland, New Zealand.

The lateral tibial posterior slope (LTPS) and the lateral meniscal bone angle (MBA) are important geometrical features of the knee joint and have therefore been of interest in the setting of anterior cruciate ligament injury (ACL) and ACL reconstruction. An emerging body of evidence suggests that LTPS is an independent risk factor for primary and recurrent ACL injury. Furthermore, biomechanical and clinical evidence is emphasizing the crucial contribution of the lateral meniscus to rotatory knee stability. Read More

Treatment of post-meniscectomy knee symptoms with medial meniscus replacement results in greater pain reduction and functional improvement than non-surgical care.

Knee Surg Sports Traumatol Arthrosc 2021 Apr 21. Epub 2021 Apr 21.

Northwell Health Physician Partners, Orthopaedic Institute at Lenox Hill, New York, NY, USA.

3D-bioprinting ready-to-implant anisotropic menisci recapitulate healthy meniscus phenotype and prevent secondary joint degeneration.

Theranostics 2021 5;11(11):5160-5173. Epub 2021 Mar 5.

Clinical and Translational Research Center for 3D Printing Technology, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine, Shanghai, 200011, China.

Disruption of anisotropic phenotypes of the meniscus would contribute to OA progression. Exploring phenotype changes of the anisotropic meniscus in joint degeneration would help understand the biologic interaction between the meniscus and OA, and further facilitate the therapeutic strategies of meniscus injury-related joint degeneration. Meanwhile, engineering biomimetic meniscal tissue mimicking the anisotropy of the healthy meniscus remains a challenge. Read More

Department of Joint Surgery and Sports Medicine, Tokyo Medical and Dental University Graduate School of Medical and Dental Sciences, Bunkyo-ku, Tokyo, Japan

The meniscus is important for load distribution, shock absorption and stability of the knee joint. Meniscus injury or meniscectomy results in decreased function of the meniscus and increased risk of knee osteoarthritis. To preserve the meniscal functions, meniscal repair should be considered as the first option for meniscus injury. Read More
