Hip Biomechanics
A 58-year-old woman with osteoarthritis undergoes total hip arthroplasty. Preoperative templating shows she has a native femoral offset of 42mm. The surgeon is discussing with the registrar the importance of restoring offset and its effects on hip biomechanics, abductor function, and implant stability. The patient has concerns about leg length and wants to understand how the surgery will affect her gait. Regarding femoral offset in hip arthroplasty:
