Knee kinetic pattern during gait and anterior knee pain before and after rehabilitation in patients with patellofemoral pain syndrome

Patellofemoral pain is likely due to compressive force acting on the patella
related in turn to knee extension moment. The latter variable was assumed to be
(i) reduced during short-distance free walking in case of patellofemoral pain
syndrome and (ii) increased after therapeutic pain reduction. Peak knee extension
moment at beginning of stance phase was recorded by three-dimensional gait
analysis in 22 controls and in 23 patients with patellofemoral pain syndrome
before and after rehabilitation of knee extensors and flexors to reduce the pain.
Pain would occur mainly in stressful activities such as stair negotiation or
squatting and was quantified by the anterior knee pain scale. Peak knee extension
moment was significantly reduced in all the patients before treatment (n=23)
compared to controls, although no one had pain during free walking. In the 17
patients who experienced significant post-rehabilitation pain reduction in their
stressful activities, the peak knee extension moment was significantly reduced
before treatment compared to controls and significantly increased after
treatment, reaching values similar to control values. The peak knee extension
moment during free walking appears to be a good kinetic variable related to a
compensatory mechanism limiting or avoiding anterior knee pain and may be of
interest in assessing knee dynamics alteration in patients with PFPS.
