Discoid Meniscus


Discoid meniscus is a rare knee condition that can have a significant impact on daily life and mobility. It is caused by an abnormality in the knee anatomy, where the meniscus is shaped like a disc instead of the typical crescent shape. This abnormality can lead to knee pain, meniscus tears, and knee injuries, and it may require orthopedic care, knee surgery, and knee rehabilitation to manage properly.

Discoid Meniscus and its Impact on Knee Health

The knee is one of the largest and most complex joints in the body, and it is composed of several components, including bones, ligaments, tendons, and cartilage. The menisci are two cartilage pieces that cushion and stabilise the knee joint. A discoid meniscus is an abnormally shaped meniscus that is thicker and more substantial than a standard crescent-shaped meniscus.

A discoid meniscus can impact knee health in various ways. It can cause knee pain, especially when moving or bearing weight on the affected knee. It can also lead to ongoing instability, increasing the risk of falls, knee injuries, and additional meniscus tears. Moreover, if left untreated, a discoid meniscus can lead to degenerative knee disorders, such as osteoarthritis.

Although discoid meniscus is a rare condition, it is essential to understand its impact on knee health to facilitate a proper diagnosis and treatment plan.

Recognising the Symptoms of Discoid Meniscus

Discoid meniscus can cause a variety of symptoms that can affect an individual’s ability to perform daily activities. Recognising these symptoms to receive an accurate diagnosis and appropriate treatment is important. The following are some common symptoms associated with discoid meniscus:

  • Knee pain
  • Swelling around the knee joint
  • Stiffness in the knee joint
  • Instability or a feeling that the knee might give way
  • Locking of the knee joint
  • Catching or clicking sounds when bending or straightening the knee
  • Difficulty fully extending or flexing the knee

If you experience any of these symptoms, it is important to seek medical attention promptly. A doctor or orthopaedic specialist can perform a thorough examination and order imaging tests to make an accurate diagnosis.

Diagnosis of Discoid Meniscus in Australia

Diagnosis of discoid meniscus typically begins with a comprehensive physical examination by an orthopedic specialist. The doctor will ask about the patient’s medical history and symptoms, perform a visual inspection of the knee, and assess the joint’s range of motion and stability.

If discoid meniscus is suspected, the doctor may order imaging tests to confirm the diagnosis. Magnetic resonance imaging (MRI) is the most commonly used imaging test to diagnose discoid meniscus. This test provides detailed images of the knee joint and can detect abnormalities in the shape and position of the meniscus.


If the results of the physical examination and imaging tests are inconclusive, the doctor may recommend arthroscopy. This minimally invasive procedure involves inserting a small camera called an arthroscope into the knee joint through a small incision. The camera allows the doctor to visualise the meniscus and other structures in the knee joint and diagnose any abnormalities.

Arthroscopy is also used as a diagnostic tool to confirm discoid meniscus and identify any other knee injuries that may be present. If a discoid meniscus is confirmed, the doctor may perform arthroscopic surgery to remove or repair the abnormal meniscus.

Treatment Options for Discoid Meniscus

Treatment options can vary depending on the severity and type of discoid meniscus. Conservative approaches may be suitable in some cases, while others may require surgical intervention. It is important to consult with an orthopedic specialist to determine the most appropriate treatment plan.

Conservative Treatment

  • Rest: Resting the affected knee and avoiding activities that exacerbate symptoms can help to reduce pain and inflammation.
  • Physical Therapy: A physical therapist can design a custom exercise program to improve strength, flexibility and range of motion, which can help to alleviate symptoms and prevent further injury.
  • Pain Management: Over-the-counter pain medication, such as ibuprofen or acetaminophen, may help to relieve pain and reduce inflammation.

Surgical Treatment

In some cases, surgery may be required to treat discoid meniscus. The type of surgery performed will depend on the severity and location of the meniscus tear and the patient’s age and activity level.

Arthroscopic Meniscectomy

During an arthroscopic meniscectomy, a small camera is inserted into the knee joint through a small incision. The surgeon then uses small instruments to remove the damaged portion of the meniscus. This procedure is typically performed on younger patients with smaller, isolated tears.

Meniscus Repair

During a meniscus repair, the torn meniscus is stitched back together using sutures. This procedure is typically performed on younger patients with a larger, more complex tear located in the meniscus’s outer edge, where blood flow is higher and healing is more likely to occur.


Following surgery for discoid meniscus, rehabilitation is essential to ensure a successful recovery and prevent further injury. Rehabilitation typically involves a combination of rest, physical therapy, and a gradual return to activity and exercise under the guidance of a medical professional.

Following surgery for discoid meniscus, it is crucial to engage in proper rehabilitation to facilitate recovery and restore knee function. The rehabilitation goals include reducing pain and swelling, improving strength and flexibility, and returning to regular activities.

Timeline for Recovery

Recovery time can vary depending on the extent of the surgery and the individual’s overall health. Generally, patients can expect to use crutches for a few days post-surgery to avoid putting weight on the affected knee. Physical therapy typically begins within a week or two of the surgery and continues for several months. It may take up to six months to achieve full recovery.

Types of Exercises

  • Range of motion exercises: These exercises aim to restore full range of motion in the knee joint. Examples include ankle pumps, heel slides, and quad sets.
  • Strengthening exercises: These exercises help to build strength in the muscles surrounding the knee joint. Examples include leg presses, step-ups, and wall sits.
  • Balance and proprioceptive exercises: These exercises help to improve balance and stability in the knee joint. Examples include single-leg balance exercises, wobble board exercises, and agility drills.
  • Aerobic exercises: These exercises can help to improve cardiovascular health and overall fitness. Low-impact exercises such as swimming and cycling are recommended in the early stages of recovery.

Tips for a Successful Rehabilitation Process

  • Follow your physical therapist’s instructions: Your physical therapist will create a customised rehabilitation plan based on your needs and goals. It’s important to follow this plan closely for optimal results.
  • Be patient: Recovery from discoid meniscus surgery can take time. Be patient with the process and don’t rush your rehabilitation.
  • Stay committed: Commit to your rehabilitation program and attend all physical therapy sessions as scheduled. This will help to ensure that you make progress and achieve your recovery goals.
  • Communicate with your healthcare team: If you experience any pain or discomfort during your rehabilitation, don’t hesitate to communicate this with your healthcare team. They can adjust your program to fit your needs better.
  • Take care of your overall health: Eating a healthy diet, getting enough rest, and avoiding smoking and alcohol can all help to support your body’s healing process.
