Abstract
The robotic arm-assisted system (MAKO) has pioneered a transformative approach to hip joint restoration, excelling in reinstating innate hip joint anatomy and biomechanics. This case represents the initial application of the system in revision surgery following a cut-out complication. A 69-year-old female, previously independent and mobile, presented with left hip pain. X-rays revealed a cut-out complication of the proximal nail, necessitating revision to total hip arthroplasty due to the patient's prior activity level and implant prominence. Utilizing the robotic system, preoperative planning accurately identified limb length discrepancy and guided implant sizing. The system facilitated precise acetabular reaming and optimal component placement. The patient regained functional independence. This report also underscores the system's potential for accurate acetabulum component placement and restoration of hip joint anatomy and biomechanics in revision cases. Future advancements in this technology may expand its role in complex reconstructions and revisions, further enhancing patient outcomes in hip arthroplasty.
