The meniscus is a meniscus-shaped fibrocartilage with a triangular cross-section located between the tibial condyle and the plateau, which significantly improves femoro-tibial joint consistency and plays an important role in knee joint dynamics.The meniscus is a meniscus-shaped fibrocartilage with a

Hip fractures are estimated to affect 500,000 adults in the United States each year. They have a tremendous impact on quality of life, currently accounting for 3-7% of in-hospital mortality and a one-year mortality rate of 19.4-58%. Approximately half of all hip fractures are intertrochanteric (IT)

Periprosthetic fractures of the proximal femur are a serious problem in hip arthroplasty. The reported incidence is 3.5% 20 years after initial implantation and increases with the incidence of joint replacements. Intraoperative fractures are often associated with uncemented stems. More commonly, fra

Proximal humerus fractures are one of the most common fractures in trauma orthopedics, and most proximal humerus fractures are low-energy osteoporotic fractures in the elderly.Although the majority of proximal humerus fractures can be treated conservatively, 10-15% of fractures still require surgica

Posterior shoulder instability is usually caused by traumatic posterior dislocation or repetitive minimally invasive injury during exercise or other activities, with an annual incidence rate of 4.64 cases per 100000 people per year. Several surgical techniques for the treatment of posterior shoulder
