Osteonecrosis of the jaw (ONJ) is a multifactorial disease in patients with primary or metastatic bone malignancy or osteoporosis undergoing systemic antiresorptive therapy, where pathophysiology has not yet been fully determined. The staging of ONJ is based on severity of symptoms and extent of clinical and radiographic findings. Treatment strategies range from conservative local wound care to aggressive resective surgery of all necrotic bone. The first ONJ cases were reported in 2003 and 2004, and although significant progress has been made in our understanding of the disease, much more work needs to be done to completely explain its pathophysiology.

Sickle cell disease (SCD) is a mono-genic disorder causing chronic hemolysis, anemia, and vaso-occlusion, leading to musculoskeletal complications such as osteonecrosis, osteoporosis, and bone fractures affecting 50-70% SCD patients. These complications result from a complex interplay of genetic and physiological factors, including abnormal hemoglobin production, chronic inflammation, and oxidative stress. This review discusses the pathophysiology, pre-clinical symptoms, and clinical manifestations of musculoskeletal complications in SCD, as well as current treatment options, including pharmacological interventions, surgical procedures, and bone marrow transplantation.

Background: The location and size of necrotic lesions are important factors for collapse, The preserved angles (PAs) are divided into anterior preserved angle (APA) and lateral preserved angle (LPA), which could accurately measure the location of necrosis lesion. We used them to evaluate the effect of the location and size of necrotic lesions on collapse by finite element analysis, to offer a framework for evaluating the prognosis of osteonecrosis of the femoral head (ONFH) in clinical settings.

Methods: 3 left hip models were constructed based on CT data.

Subchondral insufficiency fracture of the knee.

Department of Orthopedic Surgery, Mayo Clinic, 200 First St. SW, 55905, Rochester, MN, USA.

Subchondral insufficiency fractures of the knee (SIFK) are a relatively common cause of knee pain, particularly in middle-aged and older adults. The SIFK is a type of stress fracture that occurs when excessive and repetitive or supraphysiologic loads are applied to subchondral bone [1]. Historically, this type of fracture was termed spontaneous osteonecrosis of the knee (SONK) until advances in MRI identified underlying fractures as well as meniscal deficiency as likely attributable etiologies.

Platelet-rich plasma (PRP) has gained increasing recognition as a promising therapeutic agent in managing rheumatic diseases. Conventional treatments, including nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, and disease-modifying antirheumatic drugs (DMARDs), primarily act on reducing inflammation but fail to address the underlying mechanisms of connective tissue degradation. PRP, an autologous preparation enriched with growth factors and bioactive molecules, is pivotal in modulating inflammation and fostering tissue regeneration.

Osteonecrosis of femoral head (ONFH) is characterized not only by ischemic bone tissue necrosis but also by cartilage degeneration, which plays an essential role in the pathogenesis of ONFH. The molecular communication between tissues contributes to disease progression, however the communication between cartilage and subchondral bone in the progression of ONFH remains unclear. In this study, we integrated transcriptomic data from ONFH cartilage and subchondral bone, exploring common differentially expressed genes (DEGs), pathway and function enrichment analyses, the protein-protein interaction (PPI) network, and hub genes to comprehensively study molecular integration.
