Abstract

We aimed to clarify differences in femoral morphology associated with post-hip fracture knee pain (PHFKP). Medical records and radiographic examinations were retrospectively reviewed to determine the relationship between PHFKP development and femoral morphology. Leg length discrepancy (LLD) and neck-shaft angle discrepancy (NSAD) were measured from hip radiographs. 202 were enrolled, of whom 64 (31.7%) developed PHFKP. The PHFKP group showed more varus NSA. Intertrochanteric femoral fractures (γ-nail or CHS) displayed a more varus NSA. Femoral morphology (varus NSA) may be involved in the development of PHFKP.
