Chronic knee pain can arise from a variety of problems, many of which will respond to appropriate exercise. The goal of these exercises is to strengthen the muscles on the medial aspect of the thigh and knee (the sides of the knees that touch if you squeeze them together) :

 

 

 

 

Rationale: These exercises strengthen the inside quadriceps by using them to straighten the knees and to keep them straight against gravity. Persistent weakness of the inside quadriceps muscle commonly occurs after knee injuries, and can also result from unconscious postural habits and/or genetics. Medial quadriceps weakness and medial knee hyper-mobility often trigger reflexes that tighten up the lateral (outside) quadriceps in an attempt to stabilize the knee, which over time results in a self-exacerbating imbalance between painfully stiff and over-used outside thigh muscles, and weak, under-performing medial knee muscles. Both acute injuries and chronic tendonitis and arthritis can arise from knee muscle imbalances. 

 

 

 

Exercise effects: Repeating these exercises frequently, even without weights or resistance, helps to €œturn on€ the medial quadriceps so that it becomes more used during walking and other activities, and breaks the cycle of under-use that leads to atrophy, pain and further weakness. Re-balancing the inside and outside thigh and knee muscles can help reduce pain, restore function and reduce risks of further knee problems.
