The meniscus is a C-shaped piece of cartilage that acts as a shock absorber and stabilizer inside the knee. Each knee has two menisci—one on the inside (medial) and one on the outside (lateral). These structures help distribute weight, protect the joint surface, and contribute to smooth, controlled movement. When a meniscus tears, patients may experience pain, swelling, clicking, catching, or a feeling that the knee is giving way. The severity of symptoms often depends on the type of tear, where it is located, and whether the knee is also affected by other conditions such as ligament injury or arthritis.
Meniscus tears occur in many ways: twisting injuries during sports, awkward landings, deep squats, heavy lifting, or sometimes simple everyday activities in older individuals with age-related degeneration. Diagnosis typically involves a physical examination and MRI to determine the tear’s size, pattern, and healing potential. Treatment is individualized, with the goal of preserving as much healthy meniscus as possible.
Yes. Many meniscus tears—particularly degenerative tears in older adults—can be managed successfully with nonsurgical treatment. The meniscus has limited blood supply, and degenerative tears often behave more like “fraying” than a clean separation. These tears may cause aching, swelling, or stiffness, but they frequently improve with time and rehabilitation.
Physical therapy is the most important component of nonsurgical care. Strengthening the quadriceps, hamstrings, hip abductors, and core helps restore joint stability and reduce stress on the meniscus. Therapy also improves motion, decreases swelling, and allows patients to return to daily activities.
Over-the-counter anti-inflammatories, ice, temporary activity modification, and the use of a brace during higher-demand activities can further reduce symptoms. Some patients also benefit from corticosteroid or viscosupplementation injections to control inflammation or improve joint lubrication. Nonsurgical management is often effective within 4–8 weeks for many degenerative or stable tears.
However, tears that cause persistent mechanical symptoms—such as catching, locking, or repeated giving way—may require surgical evaluation, particularly in younger or active individuals.
When surgery is needed, meniscus tears are typically treated using knee arthroscopy, a minimally invasive technique performed through small incisions with a camera and specialized instruments. Arthroscopy allows the surgeon to evaluate the tear directly and determine the best treatment approach: repair or partial meniscectomy.
Because the meniscus is vital for long-term joint health, the guiding principle is “repair when possible, remove as little as necessary.”
Meniscus repair involves stitching the torn meniscus back together so the tissue can heal. Not all tears are repairable; success depends on several factors:
- Location: Tears in the outer “red-red” or “red-white” zones (areas with blood supply) have higher healing potential.
- Pattern: Vertical longitudinal tears, bucket-handle tears, and peripheral tears are more repairable.
- Patient factors: Younger, active patients tend to heal better; stable knees with intact ligaments also support successful repair.
Modern techniques—inside-out, outside-in, and all-inside devices—have improved the success rate significantly. Repair allows patients to maintain normal knee biomechanics and decreases the risk of arthritis later in life. Recovery includes a period of protected weight-bearing and limited bending to allow the repair to heal properly.
Meniscus repair is especially important in athletes and active individuals who want to preserve knee function for decades.
When the tear is too degenerative, fragmented, or located in the inner “white-white” zone with little blood supply, repair may not be possible. In these cases, a partial meniscectomy removes only the damaged, unstable pieces of meniscus while preserving as much healthy tissue as possible.
This procedure often provides rapid relief of mechanical symptoms like catching and locking, and patients frequently return to activity within a few weeks. However, removing even small portions of the meniscus increases contact stress on the cartilage, which can accelerate wear over time. For this reason, the decision to perform a meniscectomy is made carefully and only when repair is not feasible.
Tears of the meniscus root—where the meniscus anchors into the tibia—behave more like a total meniscectomy because they eliminate the meniscus’ ability to distribute load. These tears often occur in middle-aged individuals and can lead to rapid cartilage breakdown if untreated.
Root repair uses sutures passed through bone tunnels to reattach the root to its insertion site. Patients typically follow a strict rehabilitation program with limited weight-bearing to allow proper healing. When treated early, root repair can significantly improve pain and may slow or prevent progression toward osteoarthritis.
In younger, active patients who previously underwent a large meniscectomy and now have persistent pain or early arthritis, meniscus allograft transplantation may be considered. This procedure replaces the missing meniscus with a size-matched donor graft to restore shock absorption and improve joint mechanics.
Meniscus transplantation is not recommended for patients with advanced arthritis but can be highly effective when combined with correction of alignment or ligament instability.
Meniscus tears are one of the most common knee injuries, but with the right treatment plan, most patients can regain comfort, stability, and full function. Options range from physical therapy and nonsurgical management to arthroscopic meniscus repair, partial meniscectomy, root repair, and even transplantation in select cases. Because every tear behaves differently, the best treatment depends on your age, activity level, tear pattern, and overall knee health.
If you are experiencing knee pain, swelling, catching, or instability, please contact Dr. José Vega’s office in Cleveland to schedule a consultation. Together, we can evaluate your MRI, discuss your goals, and design a customized treatment plan to help you return to the activities you enjoy.
