Quick Answer: A meniscus tear is a common knee injury affecting the rubbery cartilage discs that cushion the joint. Treatment depends on the size, location, and pattern of the tear, along with the patient's age and activity level. Many tears heal with physical therapy, while others require arthroscopic surgery.
With soccer fever gripping the Inland Empire as the 2026 FIFA World Cup plays out across the United States, knee injuries are on everyone's mind. The meniscus tear is one of the most common orthopedic injuries in both elite athletes and everyday patients. The AAOS estimates that approximately 850,000 meniscus surgeries are performed annually in the United States, making it one of the most frequently performed orthopedic procedures. However, surgery is not always the first or only answer.
Understanding the Meniscus
Each knee has two menisci, the medial (inner) and lateral (outer). These are C-shaped discs of fibrocartilage that sit between the femur and the tibia, acting as shock absorbers, stabilizers, and joint space distributors. Without healthy menisci, the forces of everyday movement are transmitted directly to the articular cartilage, accelerating wear and increasing the risk of osteoarthritis.
The meniscus has a limited blood supply. Only the outer one-third, called the red zone, has blood vessels and can heal. The inner two-thirds, called the white zone, receives its nutrition from joint fluid and has very poor healing capacity. This distinction matters enormously for treatment decisions.
How Meniscus Tears Happen
Acute (Traumatic) Tears
Traumatic meniscus tears typically occur during sports activities involving twisting movements, deep squatting, or sudden stops. Soccer, basketball, tennis, and skiing are common causes. The classic mechanism is a combination of weight-bearing and rotation, such as pivoting with the foot planted. ACL tears and meniscus tears frequently occur together for this reason.
Degenerative Tears
In adults over 40, meniscus tears often develop gradually without a single traumatic event. Degenerative tears occur as the meniscus tissue weakens and becomes more susceptible to tearing from everyday activities like stepping off a curb or rising from a squat. These tears are closely associated with knee osteoarthritis and are very common on MRI in middle-aged and older adults.
Recognizing the Symptoms
The symptoms of a meniscus tear vary depending on the severity and location, but commonly include:
- Pain along the inner or outer knee joint line
- Swelling that develops gradually over 24 to 48 hours after injury (unlike ACL tears, which swell rapidly)
- A popping sensation at the time of injury
- Stiffness and difficulty fully bending or straightening the knee
- A feeling that the knee is locking, catching, or giving way
Locking of the knee, where the joint physically cannot be fully extended, is a particularly important symptom. It suggests a displaced bucket-handle tear, which is a specific pattern requiring prompt surgical attention.
Diagnosis: What to Expect
A thorough physical examination, including the McMurray test and Thessaly test, can identify meniscus pathology with reasonable accuracy. MRI is the gold standard for confirming the diagnosis, identifying the tear pattern, and detecting other injuries such as ACL or MCL damage.

Treatment: Matching the Approach to the Tear
Non-Surgical Management
Many meniscus tears, particularly small peripheral tears in the red zone or degenerative tears in older adults, can be managed without surgery. A structured program including:
- Physical therapy to strengthen the quadriceps, hamstrings, and hip muscles
- Activity modification to avoid high-impact loading of the knee
- Anti-inflammatory medications to control pain and swelling
- Corticosteroid injections for pain management when inflammation is significant
A 2018 study in the New England Journal of Medicine found that physical therapy was as effective as surgery for many middle-aged patients with degenerative meniscus tears and no knee locking. This has shifted clinical practice toward a more conservative first approach for appropriate candidates.
Surgical Treatment
Surgery is indicated when symptoms persist despite adequate non-surgical management, when the knee locks, or when the tear pattern is one that can be repaired. Arthroscopic meniscectomy (trimming the torn portion) and meniscal repair (suturing the tear) are the two main approaches.
Meniscal repair is preferred when the tear is in the well-vascularized outer third and the patient is younger and active. It preserves more meniscal tissue and reduces the long-term risk of arthritis. Recovery from repair takes three to four months. Meniscectomy has a faster return to activity but removes tissue permanently, which is why surgeons aim to preserve as much meniscus as possible.
Recovery and Getting Back to Sport
Recovery timeline depends on the procedure. Following a partial meniscectomy, most patients return to light activity within four to six weeks. After a meniscal repair, return to full sport typically requires four to five months of rehabilitation. Regardless of which treatment path you take, a structured physical therapy program is essential to restore full strength and stability to the knee.
For soccer players across Southern California motivated by watching the World Cup, this summer is also a good time to assess your own knee health and address any persistent symptoms before the fall season begins.
