Robotic Hip Replacement

Who Needs Robotic Hip Replacement?

Robotic hip replacement is recommended for patients with severe hip arthritis, avascular necrosis, or hip fracture unresponsive to conservative treatment. Ideal candidates are adults with significant joint damage, good overall health, and realistic expectations. The orthopedic surgeon evaluates imaging, symptom severity, and patient fitness to determine eligibility for the robotic procedure.

Diagnosis

Diagnosis before robotic hip replacement involves:

• X-ray of the hip to assess joint space narrowing and bone damage
• MRI to evaluate soft tissue structures and detect early avascular necrosis
• CT scan for 3D pre-operative planning specific to robotic surgery
• Blood tests to check overall health and rule out infection
• Bone density scan to evaluate osteoporosis risk
• Functional assessment to measure range of motion and walking ability

The surgical plan is customized for each patient using digital imaging data before the operation.

Surgical Procedure

Robotic hip replacement is performed under spinal or general anesthesia. The surgeon uses CT-based 3D planning to guide the robotic arm in real time. The damaged joint surfaces are removed and the implant components are placed with robotic precision. The procedure takes 1.5 to 2.5 hours and results in minimal soft tissue damage compared to conventional techniques.

Robotic Hip Replacement Steps

The robotic hip replacement procedure involves:

• CT scan-based 3D pre-operative planning to design the implant placement map
• Administration of anesthesia and patient positioning on the operating table
• Making a minimally invasive incision to access the hip joint
• Registering bone landmarks so the robotic system can track movements
• Using the robotic arm to guide bone preparation and reaming with precision
• Placing the acetabular cup and femoral stem implants as planned
• Verifying implant alignment and leg length using the robotic feedback system
• Closing the incision in layers and applying dressings

After the Surgery

Recovery after robotic hip replacement begins on the day of surgery with guided walking. Hospital stay is typically 2 to 3 days. Physiotherapy starts immediately and continues for 6 to 12 weeks. Patients should avoid crossing legs, bending the hip beyond 90 degrees, and sleeping on the operated side during early recovery. Most resume daily activities within 6 to 12 weeks after surgery.

Complications of Robotic Hip Replacement

Potential complications of robotic hip replacement include:

• Dislocation of the hip implant in the early recovery period
• Deep vein thrombosis or pulmonary embolism
• Periprosthetic joint infection requiring antibiotic treatment
• Leg length discrepancy though rare with robotic guidance
• Nerve or blood vessel injury near the surgical site
• Implant loosening over many years requiring revision surgery
• Adverse reaction to anesthesia or blood loss
