Discoid Meniscus – Frisco, TX
The orthopedic surgeons at OrthoTexas, Frisco provide treatment for a wide range of knee conditions. They specialize in using advanced techniques to diagnose and treat Discoid Meniscus to improve the stability of the knee joint.

Discoid Meniscus

Each human knee has two crescent shaped cartilage structures called menisci which lie between the bones and provide support as well as cushioning to them.  The lateral meniscus is found on the outer side of the knee while the medial meniscus is located in the middle of the joint. These absorb the external shocks that may affect the femur and shin bone. The meniscofemoral ligaments join the tibia to these menisci and control the supply of blood to these cartilaginous tissues. Discoid Meniscus occurs when the shape of any of these cartilages is altered into a disc or oval shaped structureThe distorted shape of the meniscus makes it prone to injury and dysfunction.

Discoid Meniscus can be categorized as follows:

  • Incomplete – The patient has a wider and thicker meniscus compared to the normal shape
  • Complete- The tibia gets completely covered by the meniscus
  • Hypermobile Wrisberg- The meniscofemoral ligament is absent and the meniscus tends to slip into the joint although its shape may or may not have been altered

Causes Of Discoid Meniscus

  • Congenital disorders that may lead to malformations in the meniscus
  • Sports injuries
  • Twisting of the knee

Symptoms Of Discoid Meniscus

  • Knee Pain
  • Difficulty in knee movement (bending and straightening)
  • Reduced range of motion
  • A locking or popping sensation
  • Swelling and tenderness
  • Stiffness
  • The patient may feel that the joint is not stable and imbalanced
  • A popping sound may be heard when the knee is bent or straightened

Diagnosis Of Discoid Meniscus

  • Evaluation of the medical history and symptoms reported by the patient
  • The doctor may conduct a physical examination by bending and straightening the knee. In some cases, the deformed meniscus may be visible under the skin when the knee is bent
  • X-ray imaging may help to reveal enlargement of space between the tibia and shin bone if the meniscus has thickened
  • MRI imaging can help to assess any abnormality in soft tissue structures and tear in the meniscus

Treatment For Discoid Meniscus

  • Arthroscopy- A small instrument with a camera attached to it is inserted into the knee joint to view and restructure the distorted meniscus. The surgery may be performed under general or local anesthesia and the patient is usually discharged within a few hours
  • Saucerization- Surgical cutting and re-shaping of the meniscus may be recommended in case of Hypermobile Wrisberg type of deformity. In case the meniscus has a tear, the surgeon may remove the torn pieces and stitch back the cartilage retain its normal position
