Patellofemoral Pain Syndrome
What is Patellofemoral Pain Syndrome?
Your patellofemoral joint is between your kneecap (patella) and your thigh bone (femur). It makes up a part of your knee joint, being contained within the same water tight sack (joint capsule) and can be seen in the picture above. As you can see it is actually quite separate from your main tibiofemoral joint (between your shin and thigh bones). It has a differing task to the rest of your knee joint, thus tends to give different types of symptoms and therefore should be dealt with from a treatment and diagnostic sense as a subtly separate entity.
The term Patellofemoral Pain Syndrome, shortened to PFPS, relates to any pain felt arising from this and related structures. This is an interchangeable term with the also commonly used anterior knee pain (frontal knee pain)
Not everyone likes this term; it sounds like something born out of a committee. In truth it was. It came out of the realization by the academic community that not all pain coming from the knee-cap can be explained by a problem with anatomy (bones, tendons, misalignment).
- Some pain is present in the absence of altered anatomy
- Some people with altered anatomy have no pain.
- Some people with altered anatomy have pain arising from something unrelated to their anatomical variation.
Sounds complicated doesn’t it? In truth, to an experienced specialist, diagnosis is simply a quality assessment and some rational thought away. However explaining the nuances of all the potential reasons for PFPS in this forum may just send you to sleep, or give you a headache to go with your knee pain!
As specialists we recognize a number of different clinical entities that are encompassed within the umbrella term of PFPS. These include:
- OA knee
- Patella tendinopathy
- Lateral facet overload
- Patella osteochondral defect
- Symptomatic plica
- Hoffas fat pad irritation
- Chondromalacia patellae
However some folk have similar presentations of knee pain in the absence of any of these.
PFPS tends to affect women more than men, is more prevalent in adolescence but then tends to raise again as people get into their 50’s and over.
What are the symptoms of Patellofemoral Pain Syndrome?
PFPS commonly presents with pain arising from the front of the knee. It is usually located around the kneecap itself.
This pain is usually worse when more load is placed up on the knee cap. Ascending stairs seems to particularly aggravate PFPS due to the added pressure of lifting your body on a bent knee. However people will commonly struggle also with:
- Prolonged sitting
- Getting out of chairs
Some people may find that, if their pain is intense enough, the knee can feel that it will give way. People can report the knee buckles with pain, particularly when going up or down stairs.
What can I do for myself?
If you have had a sudden flare up of pain it is a good idea to treat the knee kindly, let it settle. Following the advice here on the management of an acute injury is a great place to start.
As things start to settle it is important to start to re-load your kneecap. Avoiding the use of your kneecap by walking up and down the stairs sideways, a common work around people use tends only to prolong matters.
It is often useful to start the process of rehabilitating your kneecap slowly. Starting with some simple exercises such as these. It is okay to feel some pain when doing these, but it should go off as soon as you stop exercising. They should not leave your knee aggravated.
As things start to get easier you could start to try this exercise.
Only lunge as far as you can so your knee pain is not left worse after you have done.
Once you start this journey to recovery how far you continue depends on what you wish to get back to doing. If you have a specific sport or hobby that you wish to return to then gaining the help of a rehabilitation specialist would be advised. This is something we would be able to help you with.
