Suggest Treatment For Tibial Fracture From Distance Walking

I m looking for unconventional ideas relating to a possible connection between post-surgery (hip replacement 2010) and recent left tibial fracture with 5 month convalescence , to leg fatigue from distance walking .. adding notions of neuropathy/claudication to the mix. Have had considerable rehabilitative PT. In excellent health and physical condition (daily workouts, long walks, etc.), regularly run BP numbers like 115/70 or lower, rarely higher, have eccentric blood panel consistently over years with high LDL, while eating habits would be considered stringent by most standards.
