Background: Given the superiority of meniscal repair over partial meniscectomy according to biomechanical data, the clinical outcomes of meniscal repair are likely to be better than those of partial meniscectomy for a medial meniscus root tear (MMRT). Purpose/Hypothesis: This review was designed to compare the clinical and radiological results between meniscal repair and partial meniscectomy for MMRTs. It was hypothesized that meniscal repair would result in better clinical and radiological results compared with partial meniscectomy...

Osteoarthritis (OA) is the most prevalent degenerative joint disease in animals and humans. It is characterized by pain, articular cartilage damage and joint stiffness. It has been suggested that the status of the subchondral bone compartment plays an important role in the initiation and progression of OA. Bisphosphonates have been proposed as a potential disease-modifying treatment for OA, however their effectiveness is not yet clear. Twenty-four male adult New Zealand rabbits were used to evaluate the effects of risedronate on the subchondral bone quality and cartilage degradation in a long-term model of experimentally induced OA...

Introduction: We previously demonstrated that magnesium ions (Mg2+ ) was a novel therapeutic alternative for osteoarthritis (OA) through promoting the hypoxia inducible factor-1α (HIF-1α)-mediated cartilage matrix synthesis. However, oxidative stress can inhibit the expression of HIF-1α, amplify the inflammation that potentially impairs the therapeutic efficacy of Mg2+ in OA. Vitamin (VC), a potent antioxidant, may enhance the efficacy of Mg2+ in OA treatment. This study aims to investigate the efficacy of combination of Mg2+ and VC on alleviating joint destruction and pain in OA...

Osteoarthritis (OA) is a leading cause of pain and disability, and knee is the most commonly afflicted joint. Meniscal tear due to injury or degeneration is an established factor for OA pathogenesis. Previous studies have demonstrated that meniscectomy does not reduce the OA incidence. We hypothesized that enhancing meniscal regeneration may prevent OA formation and progression. We first investigated the developmental pattern of mouse meniscus. Knee joint samples were collected at embryonic stages as well as after birth for histological and immunohistochemical studies...

Histone methyltransferase EZH2 is upregulated during osteoarthritis (OA), which is the most widespread rheumatic disease worldwide, and a leading cause of disability. This study aimed to assess the impact of EZH2 inhibition on cartilage degradation, inflammation and functional disability. In vitro, gain and loss of EZH2 function were performed in human articular OA chondrocytes stimulated with IL-1β. In vivo, the effects of EZH2 inhibition were investigated on medial meniscectomy (MMX) OA mouse model. The tissue alterations were assayed by histology and the functional disabilities of the mice by actimetry and running wheel...

If our consciousness is not prepared, it is difficult to identify a ramp lesion on preoperative magnetic resonance imaging due to its low sensitivity. In clinical practice, the prevalence of ramp lesion in the anterior cruciate ligament (ACL)-injured knee can be up to 30%, with an increased frequency in chronic ACL injuries and in revision ACL. To identify the ramp lesion, routine arthroscopic exploration of the posteromedial portion of knee using a trans-notch view during ACL reconstruction therefore seems essential...

The meniscus is largely responsible for the health and longevity of the knee. It has diverse functions, being fundamental in load absorption and distribution and even in joint stability. To preserve meniscal functions and prevent the occurrence of osteoarthritis after meniscectomy, several meniscal repair techniques have been developed. To perform meniscal repair in anterior horn, the outside-in technique is the most used. There are few devices for performing them, with most of the surgical techniques described using needles...

Meniscal injuries are extremely common in the general and athletic populations. The management strategy has switched from meniscectomy to meniscal-preserving techniques. It is nowadays extensively accepted that surgeons have to do their best to repair the meniscus and try to preserve as much tissue as possible. However, in many cases the tissue quality is poor and the tear pattern is complex. In such scenarios, meniscal repair has a lower success rate. In the present surgical technique, an arthroscopic all-inside circumferential-surrounding meniscal repair technique is presented...

Spontaneous knee haemarthrosis is a rare condition, most prevalent in the elderly with osteoarthritis. Recent reports have proposed that the source of bleeding is the peripheral arteries supplying the posterior horn of the lateral meniscus. In this case, a 62-year-old active man presented with acute postero-lateral left knee pain and swelling with limited weight bearing or movement of the knee. No recent history of trauma but history of lateral compartment dominant osteoarthritis and arthroscopic partial lateral meniscectomy of left knee...

Loading on the joints during running may have a deleterious effect on post-partial meniscectomy knee cartilage, leading to osteoarthritis. Utilizing T2-mapping measurements before and after running may enable the observation of changes in the articular cartilage of the postmeniscectomy knees compared with healthy knees. After medial partial meniscectomy, 12 volunteers underwent magnetic resonance imaging (MRI) of the both knees, before and immediately after 30 minutes of running. Quantitative assessment of articular cartilage was performed using a T2-mapping technique...
