The mechanisms are thought to be similar to the post-surgery presentation (7). Rehabilitation of soleus muscle injuries in distance runners, Uncommon injuries: sural nerve neuropathy, Dr. Alexandra Fandetti-Robin, Back & Body Chiropractic, Hamstring or not? Hypoxia acts to stimulate further fibroblast proliferation and extracellular matrix and also induces the metaplastic conversion to fibrocartilage, which can undergo enchondral ossification and result in heterotopic bone formation.1, Arthrofibrosis following ACL reconstruction can present as a focal or diffuse process limiting the mobility of the knee.
