Gastrocnemius recession, also known as the Strayer procedure, is a surgical intervention aimed at alleviating tightness in the gastrocnemius muscle, which can lead to equinus contracture and associated discomfort in the ankle and foot. Equinus contracture is a condition where the ankle cannot be flexed beyond a neutral position, defined as a 90-degree angle between the leg and foot. This limitation in movement often results in compensatory mechanisms, particularly increased motion in the transverse tarsal joint of the midfoot, which can lead to various painful conditions such as plantar fasciitis, acquired flatfoot deformity, and metatarsalgia. The procedure involves making a longitudinal incision on the posteromedial aspect of the mid-calf to access the gastrocnemius muscle. Through careful dissection of the surrounding soft tissues, the muscle is exposed, allowing for the necessary surgical modifications to relieve tension. The procedure may also involve a Z-shaped incision in the Achilles tendon, which facilitates lengthening by enabling the tendon fibers to separate as the ankle is flexed. Post-surgery, the ankle is typically immobilized using a cast, splint, or a CAM-type walking boot to ensure proper healing and maintain the ankle in the desired position.
