Study Overview
Brief Summary
The role of referred pain from the retro trochanteric region, in patients with knee pain. Defining and quantifying this sub group of knee patients in the investigators list of refered knee patients. Evaluating the effect of treatment. A randomized trial.
Detailed Description
Knee pain is a great problem in the society. Besides obvious and known causes, for which there are increasing understanding and ways to treat, there is still a rather large group of patients in which the symptoms are not easily understood and harder to treat.
This group is often characterized by having symptoms ranging from months to years, having seen several physicians, gone through several x-rays/mri´s, and various treatment with no help.
The investigators find ever more suspicion towards specific mechanisms in the hip region as a source of knee pain. It is well known in pediatric medicine that children with serious disease in the hip often debut with knee pain. This relationship is not so well established in adults.
Pain in the lower extremity can arise from inflammation or strain of the retro trochanteric muscles, and/or more indirectly if these processes impact the sciatic nerve. The later explanation is commonly known as the piriformis syndrome.
Professor Oddmund Johansen has studied this type of pain extensively. In the later years he has found interest in patients with knee pain.
