A meniscus tear happens when the C-shaped cartilage that cushions the knee splits or detaches under load, and in adults it usually comes down to one of two routes. Younger patients tend to tear it through sudden twisting during sport or daily activity, while older patients are more likely to develop tears as the cartilage gradually thins with age. Common symptoms include joint-line pain, swelling that appears within a day, occasional clicking, and a knee that sometimes locks when bent. Diagnosis is confirmed through clinical examination supported by MRI.
According to Dr. Venkata Swamy Boorgula, Best Orthopedic Hospital in Kompally, “A lot of adult meniscus tears aren’t really sudden injuries, they’re the result of a knee that’s been quietly losing cartilage for years, and then one awkward movement finishes the job.”
Has your knee been clicking, swelling, or locking when you bend it?
What actually causes a meniscus tear in adults?
Most knees can be managed without surgery for years. A specific set of signs usually means that window has closed.
Twisting movements
Classic mechanism in younger adults, especially in sports like cricket, badminton, and football, where the foot stays planted while the body rotates and the rotational force ends up going straight through the knee.
Repeated squatting or kneeling
Compresses the meniscus between the thigh bone and shin bone, and when this happens day after day in jobs that involve floor work or heavy lifting, the cartilage gradually weakens until it tears without any obvious trigger.
Age-related degeneration
Most underestimated cause we see in patients above 40, because the meniscus loses water content and elasticity over time, so something as ordinary as stepping out of a car can be enough to split tissue that was already worn thin.
High-impact trauma
Road traffic accidents and falls tends to produce complex tears that involve more than just the meniscus, and these usually need detailed imaging to map the ligament damage that almost always comes with them.
Adults with knee symptoms that don’t settle within two to three weeks should get assessed by a knee specialist before the tear progresses.
How does a meniscus tear show up in daily life?
Symptoms vary depending on where the tear sits, how big it is, and whether the torn fragment is catching inside the joint, which is why some patients feel it immediately while others only notice problems weeks later.
Swelling within the first 24 hours
Twisting incident is one of the most telling signs that something inside the joint has torn, especially when there’s no bruise on the outside and the swelling builds up steadily through the evening.
A clicking or catching sensation
When bending or straightening the knee usually means a small flap of meniscus is moving through the joint space where it shouldn’t be, and patients often describe it as the knee feeling like it has “something in it”.
The knee getting stuck mid-movement
Refusing to fully straighten is what we call a locked knee, and it happens when the torn piece has wedged itself between the bones, which is a finding that needs reasonably urgent assessment.
A persistent ache along the inner or outer edge
Knee that gets worse on stairs or when getting up after sitting for a while points strongly toward meniscus involvement rather than a muscle or ligament problem.
When swelling and locking carry on for more than a couple of weeks, the conversation often shifts toward the broader joint changes we covered in our piece on knee replacement.
Why Choose Roma Hospital?
Dr. Venkata Swamy Boorgula is MBBS, MRCS (UK), FRCS Trauma and Orthopaedic Surgery (London), with over 25 years of consultant experience in arthroscopic knee surgery and joint replacement across the United Kingdom and Hyderabad, and serves as founder and Director of Orthopaedics at Roma Hospital.
Meniscus surgery gives better long-term results when the tear is repaired wherever possible rather than simply trimmed away, because preserving cartilage today is what protects the knee from arthritis a decade later, and every patient is examined and imaged with that long view in mind.

FAQ's
Can a meniscus tear heal without surgery?
Small tears in the outer meniscus often heal with rest, bracing, and physiotherapy.
How long does meniscus surgery take?
Arthroscopic meniscus surgery typically takes around 45 to 60 minutes under spinal anaesthesia.
When can I walk after meniscus repair?
Most patients walk with crutches the same day and progress to full weight-bearing within four weeks.
Are meniscus tears more common in older adults?
Yes, degenerative tears become significantly more common after the age of 40.
