• Medial meniscus is more often injured.

• Acute ACL injury : think of lateral meniscus

• Symptoms :

  • Pain , especially in a hyper flexed knee

  • Articular effusion

  • instability

  • Flessum ( if bucket handle)

• Imaging

  • Xray should be normal. Evaluate tibial slope and varus/valgus deformity

  • MRI: gold Standard

  • Arthroscan (Especially for partial tears)

Treatment

• rest, NSAIDS, rehabilitation : for degenerative lesions

• Meniscal suture: best results with vertical longitudinal tears in the red zone (or red-white)

• Partial menisectomy (for meniscal tears that can not be sutured)

• Meniscal subtitute / allograft : rarely done (lack of long term results)
