A Sudden Severe Pain Or Popping Sound Accompanied By Swelling And A Feeling Of Looseness Of The Joint And Instability

This may be due to damage to one of the knee ligaments, and is commonly seen as a result of sports injuries concerned with a sudden impact, twisting or over stretching. If the ligament is torn or twisted it is a sprain . If you suspect a damaged ligament you should comply with the RICE procedure, but not immobilise the joint as there is a risk of stiffness and possible muscle atrophy. The injury should be clinically assessed, and may need surgery.

What Does A Knee Injury Feel Like
Depending on the underlying cause, a knee injury can cause sharp, shooting pain, a dull ache or a burning pain. You may notice swelling and your knee may feel tender to touch. You may also have difficulty bending, straightening or bearing weight on your knee and may find that your knee gets stuck . A knee injury can also make you feel as if your knee is about to give way when you try to walk on it.
You Have Significant Weakness Trying To Straighten Your Knee
Severe weakness when trying to straighten the knee, even a few days after the injury, could mean that you suffered a severe tendon injury. Common causes of weakness include patella dislocations, patella tendon tears, and quadriceps tendon tears. Patella tendon and quadriceps tendon tears are not common in youth or collegiate sports, but we will see a few of these every year.
In older weekend warriors who are wondering why their knee is weak after a serious injury, patella tendon and quadriceps tendon injuries are far more common. If you are over 35 and felt a loud pop in your knee while pushing off during tennis, or basketball then you need to consider that you have seriously injured your patella or quadriceps tendon.
After an injury to one of these large, critically important tendons, you will find that the knee will feel unstable. You will think that the knee is unable to support your weight without giving way. You should be promptly evaluated by a Sports Medicine physician to determine the type of injury you had. Both quadriceps and patella tendon injuries require surgery to repair these large essential tendons.

Causes Of Pain In The Back Of The Knee
The back of the knee is composed of various muscles, bones, ligaments, nerves and arteries. See this image to get a visual representation of the knee and all of its parts. The knee also contains fluid that lubricates and protects the joint. Many different processes can result in damage or injury to these components and cause pain in the back of the knee.
Pain Behind The Knee When Walking Or Running
The cause of pain at the back of the leg behind the knee could be hamstring tendonitis. This is caused by the tendons of the hamstring becoming inflamed, often due to overuse of the hamstring muscles, but the pain will subside after rest and first aid centred on the RICE method .
If you notice a sudden sharp pain in the back of the thigh when undergoing vigorous exercise this may be due to a pull, partial tear or tear of the hamstring, and is due to overloading the muscle. This type of injury is most often treated by a doctor. A similar pain in the calf may be due to gastrocnemius tendonitis.
A tenderness behind the knee, felt when rotating the leg inwards in the act of walking could denote an injury to the popliteus muscle. A cold pack applied for 10 minutes every hour for the first day after injury can alleviate the symptoms.
All the muscles at the back of the leg can be subject to cramp. This is a common condition and occurs when a muscle goes into spasm. The symptoms are a tightening of the muscle accompanied by pain. Amongst other causes, it could be due to dehydration, muscle fatigue or a restriction of the blood supply to the affected muscles. Cramp is not serious and can be relieved by relaxing, massaging and stretching the affected muscle.

Burning Pain In Knee When Kneeling

Many people immediately believe they have knee arthritis when they feel pain as they kneel. However, sharp burning pain in knee areas when kneeling does not mean you have to acquiesce to a lifetime of painful arthritis.
Sharp, burning pain in your knee might just mean you have sore muscles.
Picture the anatomy of your knee. The thigh muscles and lower-leg muscles are both attached to your patella or knee cap with tendons.
When you strain your muscles, they fill up with lactic acid, giving them that painful tight sensation after you exercise. Tight muscles d not flex. So as you attempt to flex your knee and muscles do not respond with proper stretching, you may feel a burning sensation in your knees.

Referred Pain To The Knee
There are several conditions in which a person can develop knee pain, despite any pathology being present in the knee whatsoever. The lower back and hip joint are both known to refer pain as far as the knee and even beyond when problems arise. Conditions of the spine where the discs or joints become compromised, potentially leading to a pinched nerve, can result in pain down the leg. If the L3-4 and L4-5 spinal levels are affected, you may experience pain that refers to the knee. If you develop an onset of pain that seems to travel to the knee and is accompanied by a new onset or change in your back pain, it may be suitable for you to be seen by a health professional who can help determine whether your pain is knee related or coming from your lower back.
There are several muscles around the hip joint that are known to refer pain down to the knee. When a muscle becomes tight and irritated, pain can often be felt beyond the borders of that muscle, and in the case of some of the muscles on the front or side of the hip, we will often feel the pain spread down as far as the knee. Many cases of knee pain are blamed on the iliotibial band , however, often, the problem is higher up in the hip. There should always be an assessment of the hip whenever there is knee pain.
Your Knee Feels Unstable Or You Felt A Pop
Most ACL tears and patella dislocations occur from a twisting, non-contact injury. A typical story is that you were turning or twisting hard, and you felt a pop. As I mentioned earlier, most patella dislocations will reduce or go back into their usual place on their own. But if your patella remains dislocated the knee will look strange.
If you felt or heard a loud pop as you twisted or turned to avoid another player, then you may have torn your ACL. Other causes of popping include a patella or kneecap dislocation. If you felt or heard a loud pop in your knee, then there is a strong chance that you have a severe knee injury. Most ACL injuries and patella dislocations are non-contact injuries. A running back turning to head upfield. A striker moving laterally to avoid the defense. These are familiar stories when we see high school and college athletes who have torn their ACL.
This post dives further into the immediate management of suspected ACL injuries.

Knee Pain And Problems
Knee pain is a common complaint among adults and most often associated with general wear and tear from daily activities like walking, bending, standing and lifting. Athletes who run or play sports that involve jumping or quick pivoting are also more likely to experience knee pain and problems. But whether an individuals knee pain is caused by aging or injury, it can be a nuisance and even debilitating in some circumstances.
Types Of Knee Pain When Bending
Pain in the Knee, with Locking in the Joint
Inside the knee joint, there are two C shaped pieces of cartilage called menisci, which keep the surfaces of the upper leg bone and lower leg bones from grinding against each other. Injuries to this cartilage usually result from a trauma, like landing a jump or twisting your knee. You may also notice problems with range of motion, walking, or even a locking sensation in the joint. Resting the knee and managing inflammation will help heal minor tears, while physical therapy can help strengthen and stabilize it.
Pain Behind the Kneecap
Patella-Femoral Syndrome is a term that describes joint pain between the kneecap and upper leg bone. Under the kneecap is a smooth cartilage lining that creates a gliding surface between the bones, and if it softens or wears away it can result in pain and inflammation. According to Neuromuscular Specialist and co-founder of the Performance Institute in New York City, major contributing factors to this knee pain are poor alignment when landing, as well as imbalanced quadricep muscles, which can pull the kneecap side to side. Strengthening the quads and stretches to lengthen hamstrings and calfs will help reduce the risk of injury.

What Causes Knee Pain When Bending

The knee is one of the largest and more complex joints of the human body. There are four bones that account for this articulation. We have the femur , patella , and both the tibia and fibula . Movement at the knee joint primarily occurs in a forward to backwards manner , and this can be appreciated when we run, kick a soccer ball, or go up and down the stairs. There are smaller accessory movements that also occur at the knee as well, but how much is usually controlled by many strong ligaments surrounding the knee joint.
The knee is one of the most important weight-bearing joints, and it is fundamentally involved in most of the activities we carry out during our day. Our weight-bearing joints are built to withstand large physical forces that are transferred between our body and the ground during activities such as jumping or running, and the knee is no exception here. The bodys demands on the knee make it susceptible to a variety of painful conditions ranging from direct trauma, repetitive strain injuries, to arthritis from long-term wear and tear. Pain or injury to this joint can therefore be highly disruptive to our quality of life. Understanding where your pain is coming from or why you may have pain in your knee is important, and this article will aim to guide and educate you as to what may be going on with your knee, the causes of knee pain, and whether you should be seeking treatment.
