Why does the inside of my knee hurt when I get up from the floor?

Why full bending loads the inner meniscus

When the knee is fully bent, as in cross-legged sitting, kneeling back on the heels or a deep squat, the thigh bone rolls back onto the rear horn of the meniscus. The inner meniscus is less mobile than the outer one, so it takes more of that pressure.

Rising adds a twist and a heavy push through the bent knee. If the rear of the meniscus is frayed or torn, or the cartilage there has thinned, that is exactly when it hurts. Sitting cross-legged also opens the inner knee and stretches the MCL, which can be sore after an old sprain.

What it may be

• Posterior horn tear of the medial meniscus: deep inner pain on full bending and rising, sometimes catching, very common after 40
• Inner-knee osteoarthritis: aching and stiffness when getting up, with grinding and less bend than before
• Meniscal root tear: sudden pain, often a pop, in an older adult while squatting or rising, followed by pain on walking
• MCL strain: soreness on the inner side when sitting cross-legged or with the leg turned out

Making floor sitting and rising easier

In the majlis, at family gatherings or during prayer, sit with the painful leg stretched out or slightly bent rather than tucked under you, or use a floor cushion or a low stool. When getting up, roll onto the good knee, put one foot flat, and push up with your hands on a firm surface or the wall.

Avoid deep squats for chores for a few weeks. Strengthening the thigh and hip muscles and gentle range-of-motion work help most people. Many find that once the knee calms down, floor sitting returns gradually, sometimes with a cushion.

When to see a specialist in Doha

Book an assessment if rising from the floor has been painful for more than four to six weeks, if the knee catches, locks or swells, or if you felt a pop while squatting. A sudden pop and inner pain in an older adult deserves prompt review, because meniscal root tears can lead to faster joint wear if missed.

At Aman Hospital, Dr. Gelber examines the knee in deep bend, checks for meniscus signs and reviews standing X-rays. An MRI is used when a tear would change the plan.
