Knee pain due to work and sports

Knee pain is a common complaint. The pain is mainly felt when bending or turning the knee, but can later also be present at rest. Knee pain is an annoying complaint because we use the knee a lot. This article discusses three knee conditions that are little known, but cause a lot of pain.

What is knee pain?

Knee pain involves pain in the knee, usually the front but sometimes also the side. The pain prevents normal use of the knee. Knee pain is mainly caused by sports, but also by other overloads. Work is also a major cause, such as professions that require you to sit on your knees a lot or bend your knee a lot.

Chondromalacia Patellae

Chondromalacia Patellae (CP) involves inflammation of the underside of the kneecap. This condition mainly occurs in athletes, but also in people who bend the knee a lot for their work. Twisting the knee is also a risk factor. The back of the kneecap is covered with a layer of cartilage (meniscus) along which the end of the femur slides. When something goes wrong here, irritation and pain occurs in the kneecap. This may be the case with acute trauma or a previously sustained injury.
The complaints consist of pain when bending the knee, which worsens when the knee has rested for a longer period of time. The pain is mainly felt on the front and inside of the knee.

Partellafemur Pain Syndrome

This is a common pain complaint seen in athletes. It is pain that comes from the connection between the patella, also known as the kneecap, and the thigh bone. Partellafemoral Pain Syndrome (PFPS) is often caused by sudden overload, for example jumping or running, but also by putting great pressure on the kneecap in some other way. The complaint is mainly seen in athletes such as runners, but other sports that involve a lot of running and jumping are also at increased risk. In addition, this complaint often occurs in people who sit for long periods of time for their profession, with their knees bent.
The symptoms include knee pain that worsens when walking or exercising. Sitting with the knee bent is also painful . In contrast to many other knee complaints, the pain in PPS worsens more when descending stairs than when going up stairs. The knee often shows no swelling or very mild swelling. The doctor may find it difficult to find anything by scanning the knee.
Over time, the cartilage of the kneecap becomes thinner and weaker. This can quickly cause bruises. The kneecap becomes inflamed. The complaints develop slowly and become increasingly worse. It is remarkable that the pain complaints are much less or even disappear with rest. The PFPS can be considered when the pain complaints last more than six weeks.

Anteroir Knee Pain

Anteroir Knee Pain (AKP) is a pain felt at the front of the knee. AKP can arise as a result of overload due to sports and work. Runners have to deal with this more often. AKP can also occur after an accident. In young people it mainly occurs at the beginning of the growth spurt. Sometimes Anteroir Knee Pain does not go away and young people have to live with chronic pain. Military personnel have an 18 percent chance of developing AKP due to knee strain.
The pain complaints worsen when the knee is used, such as walking, climbing stairs and cycling. The complaints largely disappear with rest . When the muscles are warmed up, the pain seems to diminish, but returns to rest. Sitting for long periods of time with bent knees worsens the pain. Noteworthy is the cracking or popping sound that the knee sometimes makes.


The treatment of the above three conditions often consists of rest, alternating with training under the supervision of a physiotherapist. Strengthening the hamstring and thigh muscle is central. In addition, painkillers and/or anti-inflammatories may be prescribed. Taping the kneecap or wearing a brace is sometimes used. However, this has no proven effect. In some cases, surgery is necessary. It is also checked whether the foot position is normal. An abnormal foot position can also cause one of the above knee conditions.
