Management of Suspected Meniscus Tear in Adults

Initial Diagnostic Approach

The American College of Radiology recommends starting with plain radiographs (standing AP, lateral, and Merchant views) to rule out occult fractures, assess for early degenerative changes, and evaluate joint space in patients with suspected meniscus tears 2
MRI without contrast is recommended if pain persists after initial conservative treatment or if radiographs show joint effusion, as MRI has 96% sensitivity and 97% specificity for meniscal tears 3, 4
MRI is particularly valuable in patients aged 45-55 years, where meniscal tears are often incidental findings and may not be the pain source 2

The American College of Sports Medicine recommends structured physical therapy and exercise therapy for at least 3-6 months as the initial approach for managing suspected meniscus tears in adults without trauma or OA 1
Patient education about the degenerative nature of the condition and activity modification to reduce mechanical stress are essential components of conservative management 1
If inadequate response after 3 months, consider intra-articular corticosteroid injection 1

The BMJ recommends against arthroscopic partial meniscectomy for degenerative meniscal tears, even in the presence of mechanical symptoms such as catching or locking 1, 5
High-quality evidence demonstrates no clinically meaningful benefit over conservative treatment for degenerative tears 1
Multiple randomized controlled trials show no significant differences in functional improvement between arthroscopic partial meniscectomy and physical therapy in middle-aged patients with degenerative tears 5

Do not rush to surgery based on MRI findings alone, as degenerative meniscal tears are common age-related findings that do not benefit from arthroscopic intervention 1
Do not interpret clicking, catching, or "locking" sensations as surgical indications, as these mechanical symptoms respond equally well to conservative treatment 1
