Results of Lateral Meniscectomy

The menisci perform crucial tasks for the normal functioning and homeostasis of the knee. Meniscus removal, which is still necessary in many instances, reduces the contact areas and increases the peak stresses in the femorotibial joint which in turn may cause cartilage wear, pain and loss of knee function. The greater the tissue mass excised, the more important the degenerative changes. This process, so-called postmeniscectomy syndrome, is worse in the lateral compartment, due to its particular features. Arthroscopic partial lateral meniscectomies gives excellent short-term outcomes. However, their results deteriorate overtime and are associated with a high incidence of arthritic changes and low functional outcomes. A cautious meniscal removal policy is warranted to avoid these deleterious effects.
