Knee symptoms vary greatly depending on what is going on in and around the knee joint. There may be burning knee pain, sharp pain, instability, stiffness or difficulty with certain activities. Each of these indicates different knee problems, and by thinking about what we feel, we can work out what is wrong and what to do to treat it.
These knee symptoms may indicate a fairly minor problem such as cartilage irritation or a minor ligament sprain, or they may be a sign of a more serious problem such as advanced arthritis or a ligament tear. It may even be that the problem isn’t in the knee itself but that the pain is referred from somewhere else, such as the lower back.
Different injuries will produce different symptoms. Here we will look at the most common symptoms associated with knee pain and how to use those symptoms to work out what is wrong. From there, you can find the best way to treat your knee pain and stop it from coming back.
We will start with a brief overview of the different knee symptoms and then go on to look at each one in more depth. Find the one that best describes your pain.

Think about your knee symptoms. Are there particular activities when you really notice the pain or things you just don't like to do anymore because it hurts too much? Does your knee make strange noises? Does it look slightly different to the other knee? Let's look at the most common knee symptoms and what they mean.
Forces up to 550% body weight go through the joint when running. Running knee pain is usually due to either training errors, poor biomechanics or muscle imbalance.
In the Running Knee Pain diagnosis section, we look at why people get pain when they run, and how to prevent and treat this common problem.

Knee locking occurs when something gets stuck in the joint, stopping you moving the knee. In most cases, it stops you being able to straighten the knee. You often have to wiggle the knee around before it will then move.

Virtually any knee problem may be accompanied by swelling, but different types of swelling lead to different knee pain diagnosis e.g. whether it comes on suddenly or builds up gradually.
section we look at the most common causes of swelling, what they mean, commonly associated knee symptoms and how to treat them.
Muscle cramp is a common problem, particularly during or after exercise, or at night time. It can been extremely painful and whilst the cramping may only last for a few minutes, the calf may remain painful for a few hours or even days.

Burning knee pain usually indicates that there is swelling inside the knee joint. This may be from a medical condition or an injury. In some cases it may be a sign of a problem elsewhere such as nerve compression or an underlying medical condition.
In the burning knee pain section we look at all the possible causes, associated knee symptoms, how to identify which you have and if it's serious.
A sudden, sharp pain in the knee usually indicates one of two things. Either something is getting squashed e.g. bone or soft tissue, or there is a problem in one of the nerves. The pain may be localised to the knee or spread down the leg.
In the sharp knee pain section we look at the possible causes, how they present and what activities are typically affected.
Knee stiffness may develop as a result of an injury or a medical condition. It may develop suddenly or gradually and often fluctuates. Stiffness when you first wake up that settles once you’re moving about is a classic feature of
which is most common in the over 50’s.
In the stiff knee section, we look at the most common causes of knee stiffness, how to make an accurate knee pain diagnosis, and the most effective treatment options.
A great deal of force goes through the knee when we do any activities with a bent knee e.g.squatting down places a force seven times body weight through the knee. There may be a problem inside the knee joint or in one of the surrounding soft tissues.
You can find out about the most common causes and how to treat them in the Knee Pain When Bending section.
Some knee symptoms tend to get worse with prolonged inactivity e.g. office workers sitting
for long periods. The pain may start while you are sitting or when you
first get up. The most common causes are:
Runners Knee: causes pain and stiffness at the front of the knee
Arthritis: changes in the bone caused by wear and tear or inflammation
Osgood Schlatters: common in adolescents, particularly after a growth spurt.
Kneeling puts pressure through the front of the knee and primarily aggravates three conditions:
Housemaids Knee: a common problem for people who spend long periods kneeling e.g.
Osgood Schlatters: common in adolescents, particularly after a growth spurt.

Another option is to think about where the majority of your knee symptoms are. There may be pain at the front of the knee, swelling behind the knee, discomfort on the side of the knee or below the joint or it may be the kneecap that is causing problems.
Visit the knee pain diagnosis section to find out how to use the location of your pain to work out what your knee symptoms mean.
A bony lump just below the kneecap is a classic sign of Osgood Schlatters. This condition is common in teenagers and young adults particularly after a growth spurt. Tension on the tendon just below the kneecap damages the bone, which often results in a hard lump on the front of the shin.
Find out more about the common causes, knee symptoms, diagnosis and treatment options in the Osgood Schlatter section.
This is when the knee buckles underneath you without you being able to control it. You may feel unsteady or even stumble or fall to the ground. It usually indicates a
1) Ligament injury: usually caused by sudden twisting, a force through the knee or the knee bending backwards the wrong way
