If you have calf cramps at night, then the &#8220;gastroc&#8221; could be the cause of your knee pain.<\/p>\n<p>This one is pretty easy to understand. The tendons of the two heads of the <strong>gastrocnemius muscle<\/strong> attach separately <em>above<\/em> the knee on the back sides. When a muscle crosses a joint, it acts on it mechanically to increase <strong>joint pressure (which can cause pain)<\/strong>. The &#8220;gastroc&#8221; is no exception, but unlike other joint-crossers that are active in moving the joint, the gastroc only assists in bending the knee. It helps stabilize it, but it&#8217;s action is mainly to point the toe from it&#8217;s lower attachment to the heel.<\/p>\n<p>Since I&#8217;m a Neuromusclular Therapist (Boston area), I have to place the <img loading=\"lazy\" decoding=\"async\" class=\"alignleft size-full wp-image-1232\" title=\"gastroctrpsthm\" src=\"https:\/\/abbottcenter.com\/bostonpaintherapy\/wp-content\/uploads\/2009\/06\/gastroctrpsthm.jpg\" alt=\"gastroctrpsthm\" width=\"181\" height=\"181\" \/><strong>Trigger Points<\/strong> from the gastrocnemius muscle as it&#8217;s most important contribution to knee pain. Of the four identified TrPs, the ones nearest to the knee are most likely to cause knee pain.  1) From a functional standpoint, a tight gastroc muscle with an active TrP can pull on it&#8217;s tendon at the knee to cause localized pain. 2) The attachment Trigger Points&#8221; that form where muscle and tendon fibers come together (musculotendinous junction) to connect to the bone have radiating pain to the back of the knee.<\/p>\n<p>The <strong>soleus muscle, <\/strong>underneath the gastrocnemius, has one Trigger Point<strong> <\/strong>near the knee that can cause some pain behind the knee, but most soleus TrPs refer locally in the calf and downward.<\/p>\n<p><strong>Trigger Points in the calves are activated or perpetuated by several factors<\/strong>, but mostly by <strong>overload<\/strong> like from sports or walking uphill or in high heels, or from <strong>prolonged shortening<\/strong> like from having the toes pointed downward in bed or driving long distances pressing on the gas pedal or sitting on a bar stool with the heels hooked on a rung. They can also be activated by <strong>deconditioning or immobility<\/strong> as when in a walking cast, or perpetuated by <strong>bending forward<\/strong> like at the sink. <strong>Compression<\/strong> like from tight knee socks can impede blood flow and cause ischemia and pain. <strong>Excess cooling<\/strong> like from an air conditioner can aggravate TrPs as can <strong>viral infections<\/strong>.<\/p>\n<p>The last three posts include those muscles most involved with knee pain, the quads, hammies, pops, and gastrocs.
