Summary

Leg length discrepancies following total hip arthroplasty have been associated with nerve palsies, gait abnormalities, and lower back pain. Leg length discrepancies are related to poorer functional outcomes and patient dissatisfaction. Failure to restore femoral offset following total hip arthroplasty has been linked to decreased range of motion and abductor muscle strength, impingement, limping, higher dislocation rates, increased polyethylene wear, and loosening of implants. Computer navigation has shown to improve the accuracy of leg length and hip offset during total hip arthroplasty. The investigators research objective is to prove the accuracy of the Intellijoint HIP™ system for determining leg length and hip offset. The investigators hypothesis was that Intellijoint HIP™, an imageless intraoperative intelligent instrument, could improve the accuracy of leg length and hip offset during primary total hip arthroplasty. The investigators plan to study this hypothesis in humans by comparing the leg length and hip offset discrepancies produced with Intellijoint HIP™ to the standard at the investigators institution, which is a pin and outrigger system.

Conditions

  • Hip Osteoarthritis
  • Leg Length Discrepancy
  • Dislocation

Interventions

DEVICE

Intellijoint HIP

Intellijoint HIP is an intra-operative, imageless intelligent instrument used to provide real-time information to surgeons about leg length and hip offset changes during total hip replacement surgery.

DEVICE

Outrigger

The outrigger is a pin and caliper device that is used to assess leg length and offset during total hip arthroplasty. It is the current standard of care at Mount Sinai Hospital.
