Summary

This prospective clinical study aimed to evaluate the effectiveness of an imageless navigation system in total hip arthroplasty (THA) via the direct anterior approach (DAA) on a traction table for reducing functional limb length discrepancy (LLD) compared with conventional techniques. Seventy-two patients with advanced hip osteoarthritis, avascular necrosis, or developmental dysplasia of the hip undergoing THA between March 1, 2021 and September 30, 2021 were included. Functional LLD was assessed using a preoperative block test. Participants were assigned to the navigation or conventional group based on patient preference. Outcomes included operative parameters, intraoperative fluoroscopy time, limb length measurements, and Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) scores.

Conditions

  • Osteoarthritis, Hip
  • Femur Head Necrosis
  • Developmental Dysplasia of the Hip

Interventions

DEVICE

Navigation system

Patients underwent total hip arthroplasty via the direct anterior approach using a computer navigation system to assist in intraoperative limb length measurement.

PROCEDURE

Conventional total hip arthroplasty

Patients underwent total hip arthroplasty via the direct anterior approach conventionally.
