Meniscal Root Tear: Symptoms and Treatment in Doha

Quick answer

A meniscal root tear is a tear where the meniscus anchors to the shin bone, so the cushion can no longer hold load and the knee behaves almost as if the meniscus were missing. Many root tears are worth repairing early, before arthritis sets in, says Doha knee surgeon Dr. Pablo Gelber at Aman Hospital in Qatar.

What is a meniscal root tear?

Each meniscus is a C-shaped cushion whose two ends, called the roots, are firmly attached to the top of the shin bone. These attachments let the meniscus act like a hoop: when you stand, it stretches slightly and spreads your weight across the joint.

When a root tears, the hoop is broken. The meniscus slides out of the joint, which on MRI is called extrusion, and the cartilage of the thigh and shin bones takes much more pressure. Laboratory studies show that the loss of function is similar to removing the whole meniscus, which is why root tears are treated differently from many other meniscal tears.

Symptoms, in patients' own words

"I felt a pop at the back of my knee when I squatted or got up from the floor"
Sharp pain on the inner side of the knee, often worse on the stairs
"It hurts to put weight on it, especially at night or after walking"
Swelling that comes and goes
Difficulty kneeling, sitting cross-legged or bending fully for prayer

Some people notice only a gradual ache, and the pop is forgotten until the MRI is reviewed.

Causes and who gets it

There are two common patterns. The medial root at the back of the inner meniscus often tears in middle age with an ordinary movement such as a deep squat, rising from sujood or sitting on the floor, because the meniscus becomes less elastic with time. Body weight and a bow-legged alignment add to the load.

The lateral root, on the outer side, more often tears in younger athletes together with an ACL tear, during football, padel or basketball. These are frequently found and repaired at the time of ACL reconstruction.

Diagnosis

The history of a pop with deep bending is an important clue. On examination there is often tenderness along the inner joint line and pain with a full squat. An MRI scan is the key test: it shows the tear at the root, the degree of meniscal extrusion, the cartilage and any bone bruising or early stress fracture under the cartilage.

In patients over around 40, standing X-rays show how much arthritis is already present and the alignment of the leg. This matters, because repair makes most sense in a knee that still has good cartilage.

Treatment options

For a younger or middle-aged knee with healthy cartilage and acceptable alignment, Dr. Gelber usually recommends arthroscopic meniscal root repair. The torn root is stitched and pulled back to its original attachment on the shin bone, restoring the hoop function of the meniscus.

Non-surgical treatment is more suitable when there is already established osteoarthritis, when the person has significant health risks, or when symptoms are mild. It includes activity modification, weight management, physiotherapy to strengthen the thigh and hip muscles, and pain relief. In a bow-legged knee, an osteotomy to realign the leg may be discussed alongside or instead of repair.

Simply trimming away a torn root is generally avoided, because it does not restore function and may speed up wear.

Recovery

After root repair the knee needs protecting while the root heals to the bone. A common plan is crutches with little or no weight on the leg for around four to six weeks, and bending limited to around 90 degrees during that time. Deep squatting, kneeling and sitting on the floor are usually avoided for around four to six months.

Most people return to office work within a couple of weeks and to light sport at around four to six months. For prayer, a chair is usually advised for some months. Your physiotherapist and surgeon will adjust the plan to the repair and your knee.

When to see a knee specialist in Doha

You felt a pop with squatting or kneeling and the knee has hurt since
Pain on weight bearing is getting worse rather than better after a few weeks
An MRI report mentions a root tear or meniscal extrusion
Night pain or sudden worsening, which can signal a stress fracture under the cartilage

Timing matters with root tears, because the cartilage can deteriorate within months. Dr. Gelber assesses these injuries at Aman Hospital in Doha.

Frequently asked questions

Will a meniscal root tear heal on its own?

A complete root tear usually does not heal back to the bone by itself, because the meniscus pulls away from its attachment. Symptoms may settle, but the loss of cushioning often remains, so it is worth an assessment before deciding to wait.

Is a root tear the same as a normal meniscus tear?

No. Many meniscal tears leave most of the meniscus working, whereas a root tear disconnects the meniscus from the bone, so it stops sharing load. That is why root tears are repaired more often.

Can I still pray normally with a root tear?

Deep bending for sujood and sitting on the floor often hurts and may increase strain on the injured root. Many patients use a chair temporarily until the knee has been treated and has recovered.

Am I too old for root repair?

Age alone does not decide it. The condition of the cartilage, the alignment of the leg, your weight and your general health matter more. X-rays and MRI help show whether repair is likely to help your knee.
