Discoid Meniscus
If you suffer from chronic knee pain related to meniscus damage, don’t hesitate to Schedule an appointment with one of our orthopedic specialists.
What is the Discoid Meniscus?
A discoid meniscus describes a congenital variation in which the meniscus develops with a thicker, wider, and more disc-shaped appearance instead of the typical crescent shape. This difference most often affects the lateral meniscus on the outer side of the knee and changes the way the meniscus distributes force and supports joint movement. The unusual shape and increased thickness can reduce stability, create abnormal motion, and place greater stress on the cartilage during daily activities and sports. Many people experience no symptoms, while others develop knee pain, swelling, clicking, popping, or episodes of catching and locking.
What is a Meniscus Tear?
The altered structure and mechanics of a discoid meniscus increase the likelihood of meniscus tears over time. Repetitive bending, twisting, pivoting, or a sudden injury can cause the abnormal meniscal tissue to split or tear more easily than a normally shaped meniscus. A tear may produce pain, swelling, stiffness, limited range of motion, and mechanical symptoms such as catching or locking. Persistent symptoms or larger tears often require medical evaluation, while treatment depends on the location, size, and severity of the injury and may include physical therapy or surgical repair to preserve as much healthy meniscal tissue as possible.
What Causes Meniscus Tears?
Sudden sports injuries commonly cause meniscus tears. Players can squat and twist the knee too far, causing the tear. Direct impact, such as a football tackle sometimes provides enough force to injure the knee. Older patients tend to suffer more from degenerative meniscal tears. Cartilage tends to weaken and wear down over time, making it more prone to tearing. Even twisting awkwardly when rising from a chair can cause enough stress to tear the tissue, if the menisci has weakened enough with age.
Symptoms of a Meniscus Tear
Patients may feel a “popping” sensation when they tear the meniscus. Most patients will maintain the ability to walk on their injured knee, even athletes can still sometimes continue playing with a torn meniscus. Over the course of several days, the knee will gradually stiffen and swell. A Baker’s Cyst may form after the knee suffers any internal injuries.
The most common symptoms of a meniscal tear include pain, stiffness, and swelling in the knee. Patients often experience a catching or locking sensation, making it difficult to move the knee smoothly. Additionally, the knee might “give way” or feel unstable, causing sudden buckling during activities. This instability can be particularly problematic during movements that require knee strength and coordination, such as walking, running, or climbing stairs. In some cases, individuals with a meniscal tear may find it challenging to fully extend or bend their knee, limiting their range of motion. This restriction can impact daily activities, such as sitting, standing, or getting up from a chair. The combination of pain, swelling, and limited mobility often prompts individuals to seek medical attention.
Meniscus Tear Procedure
During a meniscus tear procedure, the surgeon begins by making small incisions around the knee to insert an arthroscope, a small camera that provides a clear view of the damaged meniscus. Using specialized surgical instruments, the surgeon assesses the extent of the tear and decides whether to repair or remove the damaged tissue. If the tear is repairable, the surgeon uses sutures or anchors to stitch the torn pieces together, promoting natural healing. In cases where the tear is irreparable, the surgeon removes the damaged portion of the meniscus to alleviate pain and prevent further damage to the knee joint. After addressing the meniscus tear, the surgeon carefully removes the instruments and closes the incisions with sutures or sterile strips. The knee is then bandaged and often placed in a brace to stabilize it during the initial recovery period.
Meniscus Tear Recovery
Meniscus tear recovery involves a combination of rest, rehabilitation, and medical care to ensure effective healing. Initially, patients need to rest and avoid putting weight on the affected knee to reduce pain and swelling. Ice and elevation help manage these symptoms during the early stages of recovery.
Physical therapy plays a crucial role in the recovery process. Therapists guide patients through exercises to restore knee strength, flexibility, and range of motion. Adhering to the prescribed therapy regimen is essential for regaining normal knee function.
For those who underwent surgical repair, recovery also includes follow-up appointments with the surgeon to monitor healing progress and address any concerns. The use of crutches or a knee brace may be recommended to support the knee and prevent further injury.
Gradually, patients can return to regular activities, but it is important to avoid high-impact movements until fully healed. With consistent care and rehabilitation, most individuals can expect significant improvement in knee stability and function, leading to a successful recovery.
