There are many things to consider
when deciding how to treat your
torn meniscus, including the extent and location of
the tear, your pain level, your age and activity level, your doctor's
preference, and when the injury occurred. Your treatment choices are:
- Nonsurgical treatment
with rest, ice, compression, elevation, and physical therapy. This may include
wearing a temporary knee brace.
- Surgical repairSurgical repair to sew the tear
- Partial meniscectomyPartial meniscectomy, which is surgery to remove the torn
- Total meniscectomy, which is
surgery to remove the entire
meniscus. This is generally avoided, because this
option increases the risk for
osteoarthritis in the knee.
Whenever possible, meniscus surgery is done using
arthroscopy, rather than through a large cut in the
The location (zone) of the tear is one of the most
important things that helps determine treatment.
- Tears at the outer edge of the meniscus (red
zone) tend to heal well because there is good blood supply. Minor tears may
heal on their own with a brace and a period of rest. If they do not heal or if
repair is deemed necessary, the tear can be sewn together. This repair is usually successful in the red zone.
- The inner two-thirds (white zone) of the
meniscus does not have a good blood supply, so it does not heal well
either on its own or after repair. If torn pieces float into the joint space,
which may result in a "locked" knee or cause other symptoms, the torn portion
is removed (partial meniscectomy) and the edges of the remaining meniscus are
shaved to make the meniscus smooth.
- When the tear extends from the
red zone into the white zone, there may be enough blood supply for healing. The
tear may be repaired or removed. This is something the orthopedic surgeon
decides during the surgery.
Also, the pattern of the tear may determine whether a tear
can be repaired. Longitudinal tears are often repairable. Radial tears may be
repairable depending on where they are located. Horizontal and flap (oblique)
tears are generally not repairable.
