Abstract
PURPOSE OF REVIEW Meniscus injury often leads to joint degeneration and post-traumatic osteoarthritis (PTOA) development. Therefore, the purpose of this review is to outline the current understanding of biomechanical and biological repercussions following meniscus injury and how these changes impact meniscus repair and PTOA development. Moreover, we identify key gaps in knowledge that must be further investigated to improve meniscus healing and prevent PTOA. RECENT FINDINGS Following meniscus injury, both biomechanical and biological alterations frequently occur in multiple tissues in the joint. Biomechanically, meniscus tears compromise the ability of the meniscus to transfer load in the joint, making the cartilage more vulnerable to increased strain. Biologically, the post-injury environment is often characterized by an increase in pro-inflammatory cytokines, catabolic enzymes, and immune cells. These multi-faceted changes have a significant interplay and result in an environment that opposes tissue repair and contributes to PTOA development. Additionally, degenerative changes associated with OA may cause a feedback cycle, negatively impacting the healing capacity of the meniscus. Strides have been made towards understanding post-injury biological and biomechanical changes in the joint, their interplay, and how they affect healing and PTOA development. However, in order to improve clinical treatments to promote meniscus healing and prevent PTOA development, there is an urgent need to understand the physiologic changes in the joint following injury. In particular, work is needed on the in vivo characterization of the temporal biomechanical and biological changes that occur in patients following meniscus injury and how these changes contribute to PTOA development.

Abstract
BACKGROUND/PURPOSE OF THE STUDY Aim of the study was to investigate whether ellipsoid sign (ES) in the region corresponding to the cartilaginous facet of the medial femoral condyle (MFC) indicates early cartilage lesion. The finding has not been defined in the literature yet. METHODS The study was performed retrospectively with 50 patients who underwent articular cartilage examination and arthroscopy between 2015 and 2018. Patients were divided into two according to the presence or absence of ES. There were 24 patients in case group (Group A) and 26 patients in controls (Group B). Weight-bearing cartilage areas of MFC in the region where ES was found in both groups were classified according to arthroscopic Outerbridge classification (OC) and compared statistically with each other. RESULTS There was no significant difference in terms of age, gender and alignment between Group A and Group B (p > 0.05). All OC grades were higher in Group A (p < 0.001). Positive correlation between ES and MFC chondromalacia grade was detected (r: 0.671, t: 6.266, p < 0.05). CONCLUSION ES, which refers to the difference in bone density in MFC seen in antero-posterior (AP) X-Ray, is a result of changes in subchondral bone due to chronic cartilage loss. ES detected on AP X-Ray may help in early diagnosis of medial femoral articular cartilage chondromalacia, even at grade 0 or 1. We recommend searching for ES, as the earliest symptom of chondromalacia, which occurs even before MRI lesions. Future studies may reveal additional information about ES.

Abstract
In the progression of osteoarthritis, pathological calcification in the affected joint is an important feature. The role of these crystallites in the pathogenesis and progression of osteoarthritis is controversial; it remains unclear whether they act as a disease initiator or are present as a result of joint damage. Recent studies reported that the molecular mechanisms regulating physiological calcification of skeletal tissues are similar to those regulating pathological or ectopic calcification of soft tissues. Pathological calcification takes place when the equilibrium is disrupted. Calcium phosphate crystallites are identified in most affected joints and the presence of these crystallites is closely correlated with the extent of joint destruction. These observations suggest that pathological calcification is most likely to be a disease initiator instead of an outcome of osteoarthritis progression. Inhibiting pathological crystallite deposition within joint tissues therefore represents a potential therapeutic target in the management of osteoarthritis.

Abstract
Clinical efficacy of meniscal plasty and total meniscectomy under arthroscopy in treating middle-aged and elderly patients with meniscus injury were explored. One hundred and fifteen elderly patients with meniscal injuries treated in the First Peoples Hospital of Wujiang District Suzhou from May 2012 to October 2014 were retrospectively analyzed. They were randomly divided into meniscal plasty group (experimental group) and total meniscectomy group (control group). Length of stay, operation time and VAS between the two groups were compared. Knee function was evaluated before the surgery and at the final follow-up using IKDC 2000 and Lysholm score. The differences of postoperative clinical efficacy and complications in both groups were observed. Postoperative IKDC 2000 and Lysholm score in the experimental group were superior to those of control group (P<0.001). There was no significant difference in the relieving effect of knee pain between the two types of procedures (P>0.05). Shorter operation time was found in control than that of experimental group. We did not observe remarkable differences in length of stay and postoperative complication rate between the two groups (P>0.05). Both meniscal plasty and total meniscectomy under arthroscopy can effectively relieve knee pain in a short time. Meniscal plasty could remarkably alleviate the progression of knee osteoarthritis, maintain knee function and improve daily life of affected population. We considered that meniscal plasty should be served as the preferred approach in treating middle-aged and elderly patients with meniscus injury.
