Insoles for Runner's Knee
Runner's Knee covers a number of conditions which are known collectively as Patellofemoral Pain Syndrome (or PFPS).
The impact stress of running can cause inflammation in the soft tissues and bone around the kneecap. In some cases, the cartilage of the underside of the kneecap can break down causing inflammation of the synovium and pain in the underlying bone. PFPS can also be caused by abnormal tracking of the kneecap, most commonly by over-pronation of the foot during the repetitive high impact effect of running on hard surfaces.
Symptoms are a dull pain that is "behind and around" the top of the kneecap (Patella), most notably when bending the knee and walking/running downhill. Pain persists well into rest periods and can sharpen dramatically when the joint is moved after rest. Most commonly experienced by runners due to the repetitive impact nature of this activity.
Pronation control is essential to the management of ground force reaction among runners who exercise heavilly or regularly and who may naturally over pronate.
