Consider when progressive sensory abnormalities and knee extension weakness occur after trauma, surgery, or hematoma, imaging or electrophysiology suggests entrapment/conduction block, and conservative treatment has limited effect. The decision is usually made based on the course of the disease, the extent of the defect, muscle strength and skin sensation, electromyography/nerve conduction study results, overall health, and anesthesia risks, and is comprehensively assessed by a specialist team.
