Treatment of meniscal tears: An evidence based approach

Table 1 Factors influencing the risk of developing arthritis following meniscectomy

Compartment involved	Greater risk with lateral meniscectomy
Volume of resection	Greater risk with larger resection volume
Orientation of tear	Greater risk with radial tear – destroys hoops tress function
Associated conditions	Greater risk with pre-existing chondral damage
	Greater risk with ACL insufficiency
Knee alignment	Varus malalignment → greater medial compartment load
	Valgus malalignment → great lateral compartment load
Body habitus	Greater risk for larger BMI
Patient age	Greater risk over 40-year-old
Activity level	Greater risk with lower preoperative activity level

BMI: Body mass index.
