Causes of Knee Pain…

There are a huge number of causes of knee pain. Sometimes pain comes on after an injury, other times pain in the knee gradually builds up over time with no obvious cause.

To get rid of the pain permanently, it is vital to correctly identify the “cause” (what made it go wrong in the first place), not just the “symptom” (what we feel) otherwise it’s likely the problem will come back.

Let me give you an example. Say your knee is swollen and painful, you could treat that with PRICE, medication and some gentle exercises. The swelling and pain might settle temporarily (i.e. the symptoms go away), but what caused it in the first place is still there in the background. Treatment will certainly help, but as soon as you go back to doing your normal activities, your knee will most likely start hurting again and may swell. However, if you treat the weakness and tightness, you treat the “causes” of knee pain, and hey presto, problem solved.

Top 10 Common Causes of Knee Pain

Accurate diagnosis can be difficult so below I’ve listed off the major causes of knee pain with a brief outline of the most distinctive symptoms – click on the links to find out more about each problem. For a different approach to diagnosis, see the diagnosing knee pain section for a more in depth guide.

NB I’ve split injuries, caused by one off events such as a fall or sports activity, into a separate section – see the knee injuries section for more information including treatment and recovery information.

1) Runners Knee

Runners knee is one of the most common causes of knee pai

This is one of the most common causes of knee pain around the front of the knee. Don’t be fooled by the name. It is just as likely to affect those with sedentary lifestyles as it is active people. There are a number of causes including kneecap movement problems, flat feet and muscle imbalance. The most common symptoms are pain over the kneecap, swelling and pain on stairs. It usually settles within a few months.

2) Chondromalacia Patella

This is one of the most common causes of knee pain in sporty adolescents and young adults, especially females. It is caused by damage to the cartilage that lines the back of the knee cap. It results in pain at the front of the knee, especially when going down stairs, or after sitting for long periods, and can cause the knee to make funny noises when it moves.

Osgood schlatters Disease is on of the most common causes of knee pain in teenager

3) Osgood Schlatters

This is the most common cause of knee pain in teenagers, especially males. It usually develops after a growth spurt due to the bones growing faster than the muscles, causing friction. This can lead to a bony lump forming just below the patella. It can take anywhere from a few weeks to 2 years to settle.

4) Arthritis

This is the most common cause of knee pain in people over the age of 50. It is caused by wear and tear to the cartilage that lines the joint, leading to bone on bone contact. It can cause pain, swelling, weakness, limited movement and difficulty with everyday activities such as walking and going up and down stairs. There are 3 stages of arthritis. Treatment varies according to the severity of the disease, ranging from exercises to surgery.

5) Bursitis of the Knee

This is caused by inflammation of a bursa – small fluid filled sacs that lie between bones and muscles/tendons to prevent irritation. There are approximately 15 bursa around the knee. Excessive friction from activities such as jumping, running or muscle tightness can lead to swelling of one or more bursa which leads to pain. The location of the pain will depend on which bursa is affected. The symptoms tend to be general pain and swelling around the knee.

6) Bakers Cyst aka Popliteal Bursitis

A Bakers Cyst is one of the most common causes of knee pain behind the knee.

This is the most common cause of posterior knee pain, and is due to inflammation of the popliteal bursa which sits behind the knee joint. It is usually caused by fluid associated with arthritis or a cartilage tear leaking into the bursa and causing it to swell, but it can occur after any damage to the knee. The symptoms tend to be pain and swelling behind the knee, like a soft orange which can limit knee movement.

7) Housemaids Knee aka Prepatellar Bursitis

Again, don’t be fooled by the name. Nowadays, it is usually tradesmen such as roofers and carpet layers who spend long periods kneeling who suffer from this. Excessive kneeling, or less commonly, a knock to the front of the knee causes swelling in the prepatellar bursa. The most common symptoms are pain at the front of the knee, swelling (again like a soft orange) and difficulty walking, bending the knee and kneeling.

8) Jumpers Knee aka Patellar Tendonitis

Patellar Tendonitis is one of the common causes of knee pain below the kneecap

This common cause of knee pain usually affects sports players who do lots of jumping and/or kicking. These activities place lots of strain on the patellar tendon (found just below the kneecap) and can lead to small tears in the tendon. This weakens the tendon and makes it prone to further damage. The most common symptoms include pain just below the kneecap, especially after prolonged periods of rest and/or activity as well as knee stiffness first thing in the morning.

9) Iliotibial Band Syndrome aka ITBS

This is the most common cause of knee pain on the outer (lateral) side of the joint, and is often seen in runners. The iliotibial band runs down the outer side of the thigh attaching at the knee. Excessive friction on the band, caused by things such as muscle imbalance, excessive running, or running on a slope result in inflammation and pain.

Osteochondritis Dissecans is one of the more rare causes of knee pain

10) Osteochondritis Dissecans

This is one of the less common causes of knee pain. A reduced blood supply to parts of the bone cause loose fragments of cartilage and bone to break off. Whilst it can occur in any joint, it is the knee that is the most commonly affected. As well as pain, it can cause locking and clunking sensations in the knee, limited movement and swelling.
