Hi, thanks for writing to HCM.
One of the most common and feared complication of a talus fracture
is AVASCULAR NECROSIS
(AVN) that is loss of blood supply leading to the death of bone causing pain and stiffness
I suspect AVN in your case.
Propably there might have been collapse of the talus secondary to AVN leading to limp in you.
I suggest you to go for an MRI
scan which diagnoses your condition with accuracy.
Consult an orthopedic surgeon for a detailed evaluation and follow his advice.
Hope this information is helpful. Good day
