Baker's cysts arise between the tendons of the medial head of the gastrocnemius and the semimembranosus muscles. They are posterior to the medial femoral condyle . The synovial sac of the knee joint can, under certain circumstances, produce a posterior bulge, into the popliteal space , the space behind the knee.
Ganglion cysts are not limited to the hands and feet. They may occur near the knee, commonly near the cruciate ligaments, but they may occur at the origins of the gastrocnemius tendon, and anteriorly on Hoffa's infrapatellar fat pad. [14] At the shoulder, they typically occur at the acromioclavicular joint or along the biceps tendon. [15]
Shoulder problems, including pain, are common [20] and can relate to any of the structures within the shoulder. [21] The primary cause of shoulder pain is a rotator cuff tear. [20] The supraspinatus is most commonly involved in a rotator cuff tear, [22] but other parts of the rotator cuff may also be involved.
Recent research has indicated that while the test is an accurate detector of achilles rupture, it is unable to distinguish between partial tear (tear of the gastrocnemius or soleal portion only) and a complete tear of both portions.

A common injury that is normally attributed to the plantaris muscle is a condition called tennis leg. Although pain in the calf can be attributed to a rupture of the plantaris muscle, recent ultrasound research has shown that tennis leg more commonly arises from tears in the musculotendinous junction of the medial gastrocnemius. In one clinical ...
The gastrocnemius muscle is prone to spasms, which are painful, involuntary contractions of the muscle that may last several minutes. [5] A severe ankle dorsiflexion force may result in a Medial Gastrocnemius Strain (MGS) injury of the muscle, commonly referred to as a "torn" or "strained" calf muscle, which is acutely painful and disabling. [6]
The tributaries of the popliteal vein include: Veins that correspond to branches given off by the popliteal artery (see popliteal artery).; the small saphenous vein, which perforates the deep fascia and passes between the two heads of the gastrocnemius muscle to end in the popliteal vein.
A SLAP lesion (superior labrum, anterior to posterior) is a tear where the glenoid labrum meets the tendon of the long head of the biceps muscle. Symptoms include increased pain with overhead activity, popping or grinding, loss of strength, and trouble localizing a specific point of pain. [ 3 ]
