When bending or squatting, it causes knee pain.
Over time, wear and tear on your Knee can lead to pain when you bend your Knee. This is due to damage to bones, ligaments and muscles, and tendons around your Knee joint.
About 3kg of pressure is applied on your knees for every 500g of your body weight when you carry weight (e.g., when you bend, run, squat or walk).
How does a knee injury feel?
A knee injury can result in sharp, shooting pain, dull ache, or burning pain, depending on the cause. Your Knee might feel tender, and swelling may occur. Your Knee may become stuck or swollen if you have trouble bending, straightening, or bearing weight on your Knee. You may feel like your knees are about to give way if you walk on them after sustaining a knee injury.
What causes pain in the knees?
These are the most common causes of knee pain :
- Meniscus tears — Tears to the C-shaped pieces of cartilage in your Knee that are known as menisci
- Runner’s Knee — dull pain at your front Knee (patella), also known as patellofemoral pain Syndrome.
- Ligaments strains
- Tendonitis — Inflammation of your tendons
If an old knee injury isn’t properly treated, it can cause knee pain that flares up periodically or chronic (long-term) knee pain.
The most common causes of knee pain
Another common cause of knee pain is:
- A dislocated kneecap
- Iliotibial Band Syndrome — a burning sensation outside your Knee that can spread into your hips or thighs. It is often seen in runners.
- Bursitis in the Knee — Inflammation of the fluid-filled bursae (bursae), which causes swelling, warmth, and pain in your Knee joint.
- Osgood-Schlatter Disease — A condition that causes pain and swelling where your patellar tendon meets your top shinbone
- An osteoarthritis is a form of arthritis that results from wear and tear on your joints. This causes stiffness, pain, swelling, and stiffness that’s worse in the morning.
- Patellar tendonitis – Inflammation of your patellar tendon (which connects your kneecap to your shinbone); this causes burning pain below your kneecap
Knee pain can also be caused by patellar tendonitis, knee bursitis and iliotibial band syndrome. There are other causes of knee pain while bending:
- Baker’s cyst — swelling in the back of your knee due to an accumulation of fluid (synovial liquid) lubricates the knee joint. This can lead to tightening and swelling.
- Hamstring tendonitis is an inflammation of your hamstrings that causes pain behind the Knee or thigh.
- A knee injury that causes damage to the ligaments or knee joint — can usually cause severe pain and swelling, which makes it difficult for your knees to move.
- Quadriceps tendonitis – Inflammation of quadricep tendons, which causes pain above or near your Knee.
Knee pain when bent
The most common causes of knee pain when you bend behind your Knee are Baker’s cyst, Hamstring Tenonitis, or a knee injury.
Sharp pain in the Knee when you bend
Sharp knee pain caused by bending is most likely due to a torn ligament, meniscus tear, fracture of your knee joint bone, osteoarthritis, or patellar tendonitis.
Kneecap pain when bent.
Your knee pain when you bend your knees is above your Knee. This could be due to knee bursitis or osteoarthritis.
Diagnosis for inner knee pain
Your doctor will ask about your symptoms, when they began, and your medical history. Your doctor will also conduct a physical exam of your Knee to assess your range of motion and check for instability or swelling.
They may recommend an X-ray or MRI scan to examine your knees and bones more closely. They may recommend blood testing to check for conditions like Rheumatoid Arthritis or infections.
