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.
A bucket-handle tear of the knee is a specific type of meniscal injury characterized by a longitudinal tear of the medial or lateral meniscus, where a displaced inner fragment resembles the appearance of a "bucket handle". [1]
Gastrocnemius muscle weakness (in standing position) Upper motor neuron lesion (for example, hemiplegia as the result of a cerebrovascular accident) Lower motor neuron lesion (for example, in post-polio syndrome) Deficit in joint proprioception; Lower limb length discrepancy; Congenital genu recurvatum; Cerebral palsy; Muscular dystrophy
Posterolateral: biceps femorus and peroneal nerve retracted laterally; lateral gastrocnemius and soleus retracted medially; Posterior: done with the patient laying on stomach (prone); retract semimembranosus (one of hamstring muscles) until gastrocnemius becomes visible and continue until postero-medial capsule is visualized
Coblation surgery has recently been proposed as an alternative surgical approach for the treatment of recalcitrant plantar fasciitis. [30] Gastrocnemius recession is a surgical procedure that involves lengthening the gastrocnemius muscle to reduce tension in the Achilles tendon and plantar fascia. This technique improves the ankle's range of ...

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.

Acting via the Achilles tendon, the gastrocnemius and soleus muscles cause plantar flexion of the foot at the ankle. This action brings the sole of the foot closer to the back of the leg. The gastrocnemius also flexes the leg at the knee. Both muscles are innervated by the tibial nerve. [14]
