Patellofemoral pain syndrome (PFSS)
Patellofemoral pain syndrome (PFPS) is one of the most common causes of pain in the front of the knee, especially in young and physically active individuals. The condition is sometimes also referred to as "anterior knee pain" or "runner's knee". Patellofemoral pain syndrome occurs when the kneecap does not glide optimally against the thigh bone, leading to overuse of the soft tissues in and around the knee joint. The pain can develop gradually, often without any clear injury having occurred, and many experience discomfort when, for example, running, climbing stairs, or sitting for long periods. Often, the problems affect daily life and limit activity levels, but the right measures and treatment can make a big difference.
How is Patellofemoral Pain Syndrome noticed?
PFPS manifests with a range of different symptoms that can vary in intensity. Below are the most common signs of patellofemoral pain syndrome:
- Pain on the front or around the kneecap, especially during movement
- Ache that worsens with stair climbing, squats, or after prolonged sitting
- Stiffness or difficulty fully straightening the knee
- Clicking, cracking, or a sensation of the kneecap "jumping" during movement
- Often increased pain during exercise or after exertion
When and where should I seek care?
If you experience persistent pain in the knee area that does not subside with rest, self-care, or simple measures, it is advisable to seek help from a physiotherapist or at a health center. In cases of acute pain, severe swelling, or if the knee feels unstable, you should seek immediate care to rule out more serious injuries. In most cases, however, PFPS is harmless, but long-term problems may require guidance from healthcare professionals to create a personalized rehabilitation plan.
Treatment
The treatment of patellofemoral pain syndrome primarily involves offloading and adapted exercise. It is important to identify and address the factors that contributed to the onset of the problems. In many cases, it involves overuse, improper loading of the knee joint, or lack of strength in the thigh, hip, or core. By focusing on specific exercise routines, you can improve muscle function and support around the knee.
A physiotherapist can demonstrate effective exercises that strengthen, in particular, the front of the thigh (quadriceps) and the hip's stabilizing muscles. Strength training, preferably in combination with balance and mobility exercises, is the foundation of rehabilitation. It is also good to gradually return to weight-bearing activities so that the knee joint gets used to increased exertion without being overloaded. Avoid pushing through the pain – pain is the body's way of signaling that something is not right.
For some, supportive knee braces or orthoses can temporarily reduce symptoms, especially during exercise or long walks. If foot posture affects knee loading, insoles or adapted shoes can help improve gait. Taping is sometimes used to guide the kneecap correctly during movement, but this is usually a complement and should always be combined with exercise.
In cases of pronounced pain, painkillers can be used temporarily. In rare cases, if the problems do not improve after long-term exercise and self-care, surgery may be considered. However, this is uncommon – most people fully recover with the right exercise and adjusted activity levels.
What can I do myself?
There is a lot you can do yourself to reduce the risk of recurring problems and to speed up recovery. Start by analyzing how and when the pain arises. If, for example, you notice that a certain type of exercise or shoes triggers the discomfort, it may be wise to make a change. Try to stay active regularly but with varied load, and avoid monotonous or too one-sided movements for long periods.
Building strength in your legs and hips reduces the risk of overuse and improves overall body stability. Also make sure you have the right equipment for your activity – for example, shoes with good support or possibly adapted insoles if you have a foot misalignment. Mobility training and stretching of the thigh and hip muscles are good for maintaining proper balance around the joint.
By being attentive to your body's signals and taking time for recovery, you can reduce the risk of PFPS recurring. It is also wise to seek professional help if you are unsure how to proceed.

How long does it take to recover from Patellofemoral Pain Syndrome?
With the right training and adapted load, most people improve within a few weeks to a few months, but it can take longer if the problems have been long-standing.
Can I continue to train despite the pain?
Yes, but adapt your training to what your knee can handle. Avoid activities that increase pain and focus on strength training and mobility exercises until the discomfort has decreased.
Do I need a knee brace?
Many find that a lighter, elastic knee brace provides security and relief, especially during exercise or prolonged stress. Consult a physiotherapist to choose the right model.
Can patellofemoral pain syndrome lead to permanent problems?
In most cases, the problems disappear completely if you receive the correct treatment and adapt your training. Long-term or recurring pain should always be investigated.
