Anatomy of the Knee •Largest and most complex

•Vulnerable to a variety of injuries

•Weight bearing joint • Stabilizes the leg

•Most easily injured in sports

•Made up of: •Bones •Cartilage •Ligaments •Tendons

Causes continued… •Synovitis

•Inflammation of the synovial lining

•Old age•Cartilage weakens and wears thin overtime

•MEANING: torn tissue is more prone to tears!

•Patients older than 65 y.o, the rate of degenerative tears is 60%

•Menisci don’t have a strong arterial blood supply = do not heal well after being injured

•Structural differences in the collagen fibrils contribute to the ability of the menisci to be fully functional after repair

Statistic continued…•Medial menisci vs. Lateral menisci •Medial is “C”-shaped •Lateral is closer to the letter “O”

•Three zones within the meniscus:•Red-red zone •Red-white zone •White-white zone
