Large tears through the outer, vascular meniscal rim can heal when stabilized. This is performed through an arthroscopic suturing technique.
This is an arthroscopic procedure. It takes 1 to 2 hours. The meniscus is reduced to its normal position. The outer border of the graft is sewn into position with multiple vertical sutures. A counter incision on the outside of the knee may be necessary to tie down the sutures.
Outpatient procedure. Either immobilization or crutch-walking is recommended for up to 6 weeks. Normal activities of daily living are achieved at 3 months. Return to sports at 6 months post-op.
Healing rates are roughly 80%. Age, tear patterns and severity of the tear all affect the healing rate. A meniscal tear that is macerated are less likely to heal.
