Meniscus Tears and Knee Arthritis Progression

Diagnosis and Imaging

MRI can detect meniscal tears, but these are often incidental findings in older patients, with the majority of people over 70 having asymptomatic meniscal tears 1
The likelihood of a meniscal tear being present in either a painful or asymptomatic knee is not significantly different in patients 45 to 55 years of age 1
Bone marrow lesions (BMLs) visible on MRI are associated with increased knee pain, especially in males or patients with family history of osteoarthritis 1
The combination of meniscal tears and BMLs may indicate the origin of knee pain in patients with osteoarthritis 1

Conservative management is recommended as first-line treatment for most meniscus tears, particularly degenerative tears in patients over 35 years old 2
Arthroscopic surgery for degenerative knee disease (including meniscal tears) is not recommended as first-line treatment as it provides no significant benefit over conservative management 3, 4
Mechanical symptoms alone (clicking, catching) should not be considered an automatic indication for surgery in degenerative meniscal tears 3

Young patients with traumatic bucket handle tears represent a different clinical scenario than older patients with degenerative tears 5
Attempting meniscus repair in the setting of advanced osteoarthritis is unlikely to be successful and may delay appropriate definitive treatment 6
