What is the initial treatment for a medial meniscal tear?

Initial Treatment of Medial Meniscal Tear

Conservative management should be the initial treatment for medial meniscal tears, including structured exercise therapy, pain management, and activity modification for at least 6-8 weeks before considering any surgical intervention. 1

Conservative Management Approach

First-Line Interventions

• Structured exercise therapy:

  • Range of motion exercises
  • Weight-bearing exercises
  • Low-impact aerobic activities
  • Progressive strengthening of knee and hip muscles 1, 2

• Pain management:

  • Oral or topical NSAIDs as first-line pharmacological treatment 1
  • Rest and activity modification to reduce symptoms 3
  • Ice application to reduce swelling and pain 3

Second-Line Interventions

• Corticosteroid injections: Can provide short-term pain relief (up to 3 months) but should be used cautiously as they may inhibit healing and reduce tissue tensile strength 1

Treatment Algorithm Based on Tear Characteristics

1. Degenerative tears (common in patients >35 years):

   • Conservative management is strongly recommended 4, 1
   • Arthroscopic surgery is not recommended as it provides no clinically meaningful improvement over conservative management 4
   • Physical therapy focusing on functional retraining should be emphasized 3

2. Traumatic tears in younger patients:

   • Initial conservative management for 4-6 weeks 2
   • For severe traumatic tears (e.g., bucket-handle tears with displaced meniscal tissue), surgical intervention may be required if conservative management fails 2, 5

Monitoring and Progression

• Regular assessment of pain levels and functional improvement 1
• Patient education about the condition and self-management strategies 1
• Progress physical therapy as tolerated 1
• Consider imaging only if symptoms significantly worsen or change in character 1

Important Considerations and Common Pitfalls

Avoid Unnecessary Surgery

• Arthroscopic surgery should only be considered in very specific circumstances:
  • After failing conservative management for at least 6-8 weeks
  • When symptoms significantly impact quality of life
  • In the presence of true mechanical symptoms like locked knee 1
  • BMJ guidelines strongly recommend against arthroscopic knee surgery for degenerative knee disease 4

Avoid Overreliance on Imaging

• Radiographic imaging is not recommended for all patients with possible knee osteoarthritis 1
• MRI findings should be interpreted cautiously as asymptomatic meniscal tears are common, especially in patients over 35 1
• Many meniscal tears occur in the context of early degenerative knee disease 1

Special Considerations for Repair vs. Meniscectomy

• If surgery becomes necessary after failed conservative management, meniscal repair is superior to partial meniscectomy with better functional outcomes and less severe degenerative changes over time 6
• Meniscal repair shows 80% success at 2 years and is more suitable in younger patients with reducible tears that are peripheral and horizontal or longitudinal in nature 5

Conservative management remains the cornerstone of initial treatment for medial meniscal tears, with strong evidence supporting its effectiveness and the avoidance of unnecessary surgical interventions that do not provide additional benefit.
