Robotic Total Hip Replacement
Total hip replacement is one of the most successful procedures in all of medicine, reliably eliminating the pain of end-stage hip arthritis and restoring an active lifestyle. Dr. Cooper enhances these already excellent outcomes with robotic-assisted technology, bringing a new level of precision to implant positioning that manual techniques alone cannot consistently achieve.
Why Implant Position Matters
The longevity and performance of a hip replacement depend heavily on where and how the implant components are placed. Even small deviations in cup orientation or leg length can affect range of motion, increase the risk of dislocation, accelerate bearing surface wear, and compromise the patient's gait. Traditional surgical techniques rely on manual instruments and intraoperative judgment, which are subject to variability. Robotic assistance eliminates much of this variability.
How Robotic Hip Replacement Works
Using the Mako Robotic-Arm Assisted system, Dr. Cooper creates a precise, three-dimensional pre-operative plan from the patient's CT scan data. This plan defines the exact size, orientation, and position of each implant component based on the patient's individual anatomy. In the operating room, the robotic arm provides real-time tactile feedback and boundary enforcement — physically guiding the surgeon's movements to stay within the planned parameters. If the instrument deviates from the plan, the robot resists movement, ensuring accurate acetabular cup placement and leg length optimization.
Benefits for Patients
Robotic-assisted hip replacement delivers more consistent implant positioning compared to conventional techniques, which translates to lower dislocation rates, improved joint feel and range of motion, preserved leg length, and potentially longer implant survival. Patients also benefit from the same minimally invasive incisions and accelerated recovery protocols — including same-day discharge or next-day discharge — used in conventional hip replacement.
Recovery
Most patients are walking the day of surgery and are discharged home within one to two days. Physical therapy begins immediately, progressing from walking aids to independent ambulation within four to six weeks. The majority of patients return to low-impact activities within six to eight weeks and resume more strenuous activities at three to four months. The precision afforded by robotic assistance gives patients and surgeons added confidence in the durability of the result.
