Knee Pain

Picture

Generalised Knee Pain or Patellofemoral pain syndrome (PFPS) is a very common knee condition that presents to us in clinic as chiropractors.
The term PFPS is used for a variety of tissues in lesion, as there is often uncertainty in precisely what may be causing the knee pain and dysfunction. It is characterized by a poorly localised knee pain or discomfort seemingly originating from underneath the Patella (Knee cap), which is typically aggravated by running, walking up or down stairs or sitting for prolonged periods with the knees bent.

There is a growing body of evidence that suggests that the strength and coordination of the muscles of the hip are largely implicated as a cause of PFPS. A recent systematic review looked at 10 case-controlled studies where muscle activity was measured via EMG in PFPS sufferers. Moderate to-strong evidence indicates gluteus medius (GMed) activity is delayed and of shorter duration during stair negotiation in PFPS sufferers. In addition, limited evidence indicates GMed activity is delayed and of shorter duration during running, and gluteus maximus (GMax) activity is increased during stair descent.

Management of this condition initially involves reducing inflammation via rest, ice and bracing/taping. It also involves mobilization/adjustment of any joint dysfunction found in the foot, knee, hip or low back. This research also indicates that an integral part of the treatment for PFPS is the strength conditioning of the muscles of the hip, in particular Gluteus Medius.
