Pathophysiology of Meniscal Tears | Community Health

Meniscal tears are a common knee injury, affecting over 500,000 people in the US annually, with a significant impact on quality of life and healthcare costs. The pathophysiology of meniscal tears involves a complex interplay of biomechanical, biochemical, and molecular factors, including abnormal joint loading, inflammatory responses, and degenerative changes. Research by Dr. Freddie Fu, a renowned orthopedic surgeon, has shown that meniscal tears can lead to osteoarthritis, with a 10-year incidence rate of 21.1% in patients with untreated tears. The controversy surrounding meniscal repair versus replacement is ongoing, with some studies suggesting that repair may be more effective in preventing osteoarthritis. According to a study published in the Journal of Orthopaedic Research, the economic burden of meniscal tears is substantial, with estimated annual costs exceeding $4 billion. As the population ages, the incidence of meniscal tears is expected to rise, making it essential to develop effective prevention and treatment strategies, such as those proposed by the American Academy of Orthopaedic Surgeons, which include early intervention, physical therapy, and minimally invasive surgical techniques.
