Background: Percutaneous-assisted arthroplasty was introduced to minimize complications traditionally associated with minimally invasive techniques, such as component malposition and periprosthetic fracture. Proponents of percutaneous-assisted techniques have more than 15 years of clinical utilization with good outcomes. This study reports our early experience, and outcomes, with an anterior percutaneous-assisted total hip arthroplasty (AnteriorPath). Methods: A retrospective evaluation of a single-surgeon experience with the first 46 patients undergoing AnteriorPath using a cannula for acetabular cup instrumentation was compared with a similar-sized cohort undergoing traditional direct anterior (DA) total hip arthroplasty. Patients needed at least 2 postoperative visits for inclusion. Baseline preoperative characteristics, operative time, component positioning, and 6-week all-cause complications were evaluated. P values <.05 were considered statistically significant. Results: Longer operative times were experienced with the AnteriorPath vs DA THA (93.6 minutes ± 38.6 vs 79.6 minutes ± 23.2, respectively, P = .0503). There were no significant differences in component abduction (40.14° DA vs 41.95° AnteriorPath, P = .1058). A statistically significant difference was found in component anteversion (32.8° DA vs 27.25° AnteriorPath, P = .0039). There were higher rates of short-term complications in patients undergoing DA THA (9.09% DA vs 2.5% AnteriorPath). Conclusions: Early experience with an AnteriorPath demonstrates similar short-term outcomes compared with traditional DA THA. The use of a percutaneous technique has also allowed for a smaller incision, in-line acetabular cup reaming and impaction under direct visualization, and limited trauma to surrounding soft tissues. Further long-term studies with a larger sample size are needed to evaluate the potential benefits and complications of this novel technique
