Gastrocnemius Recession: Safety in the Details

Gastrocnemius recession treats isolated gastrocnemius contracture (IGC), improving ankle dorsiflexion. However, recent anatomical research highlights risk in traditional methods due to the variable anatomy of the gastrocnemius-soleus tendon.

In a cadaver study, researchers compared 10 matched pairs that underwent either a medial gastrocnemius recession (MGR) or the Baumann intramuscular recession. The study focused on measuring post-op dorsiflexion gains and involved dissection to assess nerve risk and tendon anatomy.

Key findings

Both procedures significantly improved dorsiflexion, with no difference between the two groups, and no sural nerve injuries were observed. However, 35% of specimens showed gastrocnemius-soleus muscular fusion, potentially increasing the risk of over-lengthening the Achilles tendon in standard surgical approaches.

Bottom line

While MGR and Baumann methods are equally effective, the anatomical variability, particularly in the conjoint tendon, requires surgical caution. Tailoring the procedure to the individual’s anatomy can help minimize complications.
