Torn Meniscus: What It Is, How It Happens, and How We Treat It
Understand what a meniscus tear is, the symptoms to watch for, how it’s diagnosed, and available treatment options. Learn when it’s best to see a specialist and what recovery typically involves so you can make informed decisions about your knee health.
A torn meniscus is a common knee injury that affects the cartilage pads that cushion your thigh bone and shin bone. You may get one from twisting your knee during sports or from gradual wear as you get older. Symptoms and treatments vary, and we walk through what you can expect at each step.
Quick Facts You Should Know
Your menisci are C shaped cartilage pads that help absorb shock and stabilize the knee.
Tears can occur suddenly with a twist or develop slowly from degeneration.
Common symptoms include pain, swelling, catching or locking, and difficulty fully straightening the knee.
Treatment ranges from rest and physical therapy to arthroscopic surgery depending on the tear and your goals.
Young people often have traumatic tears from sports.
Older adults may have degenerative tears that happen with everyday activities.
Some tears can heal with nonoperative care; others need repair or trimming.
We focus on restoring function so you can return to the activities you enjoy.
The menisci are rubbery wedges of cartilage that sit between your femur and tibia. They help spread load across the knee joint, absorb shock, and add stability when you twist or change direction.
When a meniscus tears, the knee loses some of that cushioning. That can cause pain with activity, swelling, and catching sensations. Over time, untreated problems can change how the joint wears, which may increase the risk of arthritis for some people.
What a Meniscus Tear May Feel Like
Pain along the joint line, often on the inside or outside of the knee.
Swelling that can appear right away or develop over 24 to 48 hours.
A catching, locking, or a sense that the knee gives way.
Tenderness when pressing along the joint line.
Limited ability to fully straighten the knee.
Pain that increases with twisting or squatting motions.
Common Ways Meniscus Tears Occur
Tears usually come from one of two patterns. Younger people often tear their meniscus during a forceful twist, pivot, or tackle. Older adults may develop a tear from gradual wear as the cartilage weakens with age.
Traumatic injury during sports or a fall.
Twisting the knee while the foot is planted.
Degenerative changes that make the meniscus fragile over time.
Repetitive squatting or kneeling that stresses the cartilage.
How We Diagnose a Meniscus Tear
We start with a focused history and knee exam. Certain exam maneuvers help us identify likely meniscal problems, and we check for swelling, range of motion, and mechanical symptoms.
If we need to confirm the diagnosis or plan treatment, imaging such as MRI is often helpful because it shows soft tissue details. X rays can rule out arthritis or bone issues.
Treatment Options: What to Expect
Treatment depends on your symptoms, the tear type and location, your age, and your activity goals. We focus on relieving pain, restoring function, and protecting long term joint health.
Nonoperative Care
Rest, ice, compression, and elevation to control pain and swelling.
Anti inflammatory medication if appropriate and recommended by your provider.
Physical therapy to strengthen muscles around the knee and improve movement patterns.
Activity modification to avoid motions that make symptoms worse while you recover.
Procedures and Surgery
If symptoms persist or there is a mechanical block in the knee, we may recommend arthroscopic surgery. Two common approaches are meniscal repair and partial meniscectomy.
Meniscal repair aims to sew the torn pieces back together when healing potential is good. It preserves meniscus tissue and helps protect the joint long term.
Partial meniscectomy trims the damaged portion when repair is not possible. This often reduces symptoms quickly but removes some cushioning.
Typical Recovery Timelines
Recovery varies based on the treatment chosen and the tear itself. Below are common timelines to help set expectations.
Treatment
Usual Recovery
Notes
Conservative care
Several weeks to a few months
Many people improve with therapy and activity changes.
Partial meniscectomy
4 to 8 weeks for many daily activities
Return to sports may be faster but depends on rehab and surgeon guidance.
Meniscal repair
3 to 6 months
Requires protected rehab to allow healing of the repaired tissue.
When You Should See a Specialist
If your knee locks or you can not fully straighten it.
If swelling or pain does not improve with a few weeks of rest and therapy.
If you have persistent instability or can not return to your normal activities.
