Plain English Summary

Background and study aims
Patellofemoral pain syndrome (PFPS) is a common disorder which describes pain in the front of the knee and around the kneecap. PFPS is sometimes called ‘runner’s knee’ or ‘jumper’s knee’ because it’s common in people who play sports. PFPS is most common in females and young adults. People with PFPS experience pain around the knee during both rest and physical activity. Triggers of pain include bending the knee, using stairs or taking part in sports or exercise. There is little agreement on the causes of PFPS, but it is thought to be caused by a misalignment within the knee and putting too much weight on the knee joint and surrounding area. Another explanation for the cause of PFPS is that the pain is caused by an irritated nerve located in either the lower back or possibly the thigh. The aim of this study is to gain a better understanding of PFPS and its causes. Patients diagnosed with PFPS in one knee will be tested for signs of altered nerve sensitivity in the affected knee compared to their unaffected knee. The results of this study might help shed light on the causes of PFPS.

Who can participate?
Adults having physiotherapy for PFPS.

What does the study involve?
Participants have a thorough screening examination to assess their condition and complete questionnaires. A physiotherapist carries out two movement tests on both knees and assesses pain levels using an established scoring system. The session takes around 90 minutes and is carried out in the physiotherapy clinic.

What are the possible benefits and risks of participating?
A benefit of taking part in this study is that all participants will have a thorough assessment of their knee problems. There are no specific risks to participants.

Where is the study run from?
Hans & Olaf Physiotherapy Centre (Hans & Olaf Fysioterapi) (Norway)

When is the study starting and how long is it expected to run for?
January 2010 to October 2010

Who is funding the study?
Norwegian Fund for Postgraduate Training in Physiotherapy (Norway)
