Is Robotic Arm Assisted Total Hip Arthroplasty More Bone Preserving than Conventional Hip Replacements and Hip Resurfacing?

Background: Total hip arthroplasty (THA) is a common procedure that increasingly being performed in younger patients. Deep acetabular reaming will result more bone loss and the need for large components to be implanted. It can also lead impingement, loosening, an altered center of rotation, intraoperative periprosthetic fracture. The purpose this study determine whether single ream, robotic arm-assisted (RAA) THA preserve greater volume stock compared conventional replacement resurfacing. Methods: We prospectively recruited 69 patients who had undergone primary using Stryker Trident Acetabular System® combination with RAA System (MAKO)® their mean weight (g) resurfacing, as measured by Brennan et al. Comparison during resurfacing versus uncemented (J Orthop Surg. 2009; 17(1): 42-46). Results: MAKO system was 9.08 g, which 29% less than 12.75 g. None cups required screw fixation. During 35-month follow-up period, there were no complications related cup placement or positioning. Conclusions: use results statistically significant preservation This approach reflects increased precision offered reaming. Surgeons may consider utilizing THA, particularly patients, better could potentially impact future revision procedures.
