Updated Patient Visit Policy Effective March 30th, 2020

Until further notice, all patients at OAL offices and facilities will not be permitted to have accompanying guests.

The only exception will be for patients who are unable to complete the visit on their own, such as a parent or guardian accompanying a minor, in which one guest will be permitted.

Any patient or guest who is sick, has a high risk of exposure or has traveled from a high-risk geographical area will not be permitted to enter any OAL offices or facilities.

Meniscus Tear - Knee Cartilage 


The menisci are cartilage structures in the knee joint that act as buffers between the bones.  The menisci are vulnerable to injury, especially during twisting motions used for sports.  Some tears in certain parts of the meniscus may heal on their own, but in many cases surgery is necessary.  Arthroscopic surgery is the accepted method of treating meniscus tears.  Because the joint is not fully opened, recovery is faster and has fewer complications than with older open surgery methods.

The knee joint is composed of three bones.  The thigh bone (femur) sits on top of the larger leg bone (tibia).  The kneecap (patella) glides in a groove on the end of the thigh bone.  The menisci are two C-shaped cartilage discs that are located on the end of the tibia. 
The outer edges of the menisci have a blood supply, which can allow injuries to heal.  The inner part of the menisci does not have a good blood supply, and tears in this area cannot heal on their own.  The menisci help to support your body weight and act as shock absorbers when you walk or run.  They also allow your knee bones to glide easily during motion.

The menisci can tear during strong twisting motions of the knee, especially when the foot remains firmly planted on the ground and the knee is bent.  Pivoting, cutting, changing directions quickly, or slowing down quickly during sports, such as football, tennis, or soccer, can cause a meniscus tear.  Older adults can experience a meniscus tear as the result of weakened cartilage and knee degeneration.

You may hear a popping noise when the meniscus tears.  Swelling, pain, and tightness may increase over several days.  You may not be able to straighten your knee, and it may buckle, catch, or lock in position.  It may be difficult for you to put weight on your leg or walk.

You should contact your doctor if you suspect you have torn your meniscus.  Your doctor will review your medical history, the circumstances leading to your injury, and conduct a physical exam.  Clinical exams, the McMurray’s test and Apley’s compression test, involve bending your knee while the doctor moves your foot and leg in different positions to assess the menisci.  Your doctor will evaluate excess fluid and swelling around your knee joint.  An X-ray may be used to see the condition of your bones. A magnetic resonance imaging (MRI) scan may be used to create a picture of your menisci and inner knee structures to help your doctor diagnose your injury.

Minor tears on the outer sections of the meniscus may be able to heal on their own if there is a good blood supply.  Ice packs, rest, and medications can help relieve pain and swelling.  Physical therapy can help strengthen the muscles that move the knee joint.  Your doctor may recommend a knee brace for sports or custom shoe inserts to support the arch of the foot.

Surgery may be recommended for larger tears on the outer section of the meniscus or for tears in the inner areas.  Most meniscus repairs are performed as outpatient surgeries.  You can be anesthetized for surgery so you are not alert or receive a nerve block to numb your knee and leg area.  Arthroscopic surgery is  favored because it is less invasive and is associated with less pain, swelling, infection, and bleeding and has a faster recovery time than open surgery.

An arthroscope is a very small surgical instrument.  It consists of a narrow tube that contains a lens and a lighting system that allows a surgeon to see inside of the joint.  Narrow surgical instruments are inserted through small incisions.  With an arthroscope,  only  small incisions, about ¼” to ½” in length, are needed, and the joint does not need to be fully opened. 

After making the small incisions, the surgeon will fill the joint space with a sterile saline (salt-water) solution.  The fluid expands the joint and allows your surgeon to have a better view of your knee.  Next, the arthroscope is inserted.  It may be repositioned to view the joint from various angles.  Your surgeon may make additional small incisions and use other slender surgical instruments to trim torn meniscus pieces.  A surgical shaver is used to smooth the remaining meniscus.

After surgery, you will be instructed to elevate your leg and apply ice to your joint to help reduce pain and swelling.  You may wear a cast or knee brace for a short period of time.  You will need to use crutches, a walker, or a cane to help you stand and walk, at first.  Your surgeon may initially restrict the amount of weight that you can put on your foot but will gradually increase it as you heal.  Physical therapy will help you gain strength and movement in your knee.

The recovery time is different for everyone.  It depends on the extent of your condition and the type of surgery that you had.  Full recovery can take several weeks or months. 

Back to Top

Your doctor may set restrictions on your activities depending on the nature of your injury.  For example, if part of your meniscus is removed, you may be restricted from running activities or lifting large amounts of weight.  Return to intense physical activity should only be done with the clearance of your doctor.  You should always wear your knee brace or protective sports gear as directed by your surgeon.
